Description

Technical Field

[0001] This application relates to the technical field of electronically controlled friction experiments. Specifically, it relates to an integrated device for modular solution preparation and electronically controlled friction regulation. Background Art

[0002] Tribology, as an interdisciplinary subject studying the friction, wear, and lubrication behaviors at the contact interfaces of objects, is widely applied in many key technical fields such as mechanical engineering, automobile manufacturing, microelectronics, biomedicine, aerospace, intelligent robots, and energy equipment. The friction performance between friction pairs directly affects the energy conversion efficiency, system stability, and component life. Especially under dynamic loads, variable speeds, micro-scales, or extreme environments, high-precision and programmable control of friction behaviors has become the core means to improve system performance.

[0003] To achieve the active regulation of the friction process, a variety of new friction control technologies have been proposed in recent years. Among them, the active lubrication regulation method based on electric fields has gradually become a research hotspot. This type of technology induces the ordered adsorption or desorption of functional components such as ionic liquids and surfactants in lubricants at the friction interface by applying an external voltage or electric field, thereby changing the lubrication state and interfacial friction characteristics. This method features a fast response speed, a wide adjustable range, strong reversibility, and friendly intelligent control, providing a theoretical basis and technical path for future intelligent friction regulation systems.

[0004] Although significant progress has been made in the experimental research of electronically controlled lubrication technology, when it comes to promoting towards practical engineering applications and industrialization, it still faces many technical bottlenecks and implementation obstacles, mainly manifested as follows:

[0005] (1) Poor adaptability of the lubrication system. Existing electronically controlled lubrication technologies are mostly limited to using specific types of lubricants, such as single ionic liquids or certain types of surfactants, and it is difficult to adapt to diverse industrial lubrication requirements. In actual engineering, lubricating fluids need to meet multiple conditions such as the type of base oil (such as water-based, oil-based), polarity, chemical stability, safety, and environmental friendliness. Currently, there is still a lack of a general system platform that supports the ratio and dynamic switching of multi-component lubricating fluids.

[0006] (2) Scattered device modules and low integration. Existing electronically controlled friction experimental equipment mostly has a non-standardized and non-integrated structure. Usually, the solution preparation, electronic control adjustment, and friction testing are dispersed in multiple independent devices. This "combined" system is inefficient in operation, has a high system response delay, large error accumulation, and does not have the ability to operate stably for a long time, severely restricting its deployment and application in engineering practice.

[0007] (3) Lack of verification of stability and reliability. Most studies only conduct short-term tests on electro-controlled lubrication behavior in ideal experimental environments, and have not yet solved problems such as the failure of electric field regulation and the destruction of lubricant structures that the lubrication system may face in long-term, high-load, complex temperature and pressure environments. There is a lack of systematic stability verification and failure tolerance mechanisms for industrial working conditions.

[0008] (4) Lack of standardized control strategies and response models. Different friction pair materials show highly non-linear personalized responses under the action of an electric field. Currently, no systematic "material-lubricating fluid-electric field" regulation parameter model or database has been established. This problem leads to the fact that most electro-controlled friction systems rely on empirical settings and manual debugging, lacking automated and intelligent control capabilities, which severely restricts their large-scale deployment and general applications.

[0009] (5) Difficult to meet the requirements of industrial scale and automatic control. The actual industrial environment poses strict requirements on the lubrication control system, such as high automation level, fast response speed, stable and reliable, and standardized interfaces (such as being compatible with PLC or DCS systems). Most existing research devices lack the ability to seamlessly connect with industrial control systems and cannot meet the requirements of functions such as "plug and play", "intelligent feedback", and "fault self-diagnosis" for the lubrication control module in an automatic production line, making it difficult to achieve standardized and mass production deployment.

[0010] Generally speaking, at present, in terms of the precise preparation of lubricating fluids, active electric field regulation, system module integration, and engineering adaptability, there are still obvious shortcomings in electro-controlled friction technology, and no complete solution that can be directly applied to industrial production has been formed.

[0023] Beneficial effects:

[0024] (1) The present invention supplies a base liquid through a base liquid supply module, prepares and stores at least two single-component lubricants using a single-component lubricant preparation module, then prepares and stores a compound lubricant using a compound lubricant preparation module according to the at least two single-component lubricants provided by the single-component lubricant preparation module, supplies the compound lubricant prepared by the compound lubricant preparation module to an external friction experiment device using a compound lubricant disposal module, and is used to extract residual liquid and perform cleaning after the friction experiment; uses a real-time monitoring module to collect experimental data (including energy consumption information of the external friction experiment device) during the friction experiment of the external friction experiment device, designs a friction experiment external voltage module, and generates a stable electric field during the friction experiment of the external friction experiment device to regulate the interfacial behavior of the compound lubricant molecules; while the main control module receives the experimental data collected by the real-time monitoring module, adjusts the electric field strength of the friction experiment external voltage module according to the experimental data, and is used to control the ratio and flow rate during the whole process of compound lubricant preparation (including the single-component lubricant preparation process and the compound lubricant preparation process). Through highly integrated and highly modular design, the present invention integrates multiple functional modules such as lubricant preparation, voltage control, friction testing, data acquisition and feedback control, overcomes the defects of scattered structure and cumbersome operation in the electro-controlled friction experiment of traditional equipment, realizes "integrated operation and closed-loop control", and significantly improves the system stability and experimental / engineering efficiency.

[0025] (2) Achieve high-precision dynamic regulation of friction performance: Through electrochemical active control means (the real-time monitoring module, the friction experiment external voltage module, and the main control module cooperate with each other), the present invention can adjust the interfacial adsorption behavior of active molecules in the lubricant in real time, so as to continuously, reversibly, and programmably regulate the friction coefficient between friction pairs (components in the external friction experiment device, and the external friction experiment device is communicatively connected to the main control unit of this equipment), meeting the refined control requirements for friction performance under dynamic loads, variable-speed motions, and complex working conditions.

[0026] (3) Support intelligent ratio and preparation of multi-component lubricants. This equipment can achieve high-precision and programmable preparation of various lubricating components such as anionic / cationic surfactants, ionic liquids, base oils (water-based or oil-based), etc., has the ability of rapid switching and flexible adjustment, effectively expands the freedom of lubricant system design, and meets different friction pair and lubrication requirements.

[0027] (4) Can achieve industrial-level automation and remote control. This equipment designs standardized interfaces and an intelligent control system, can be seamlessly docked with automation platforms such as PLC and DCS, supports programmed control, remote management, data recording, and parameter self-learning, and is suitable for automation scenarios such as intelligent manufacturing and Industry 4.0.

[0028] (5) Adapt to a variety of friction pair material combinations. The device of the present invention is compatible with the friction systems between conductor materials (such as copper, steel, aluminum, etc.) and non-conductor materials (such as polymers, ceramics, composite materials, etc.), significantly improving the material versatility of the device and the breadth of application scenarios, and being suitable for complex and diverse engineering practice requirements. In the research of electro-controlled friction, traditional solutions require at least one end between the friction pairs to be a conductor material, such as conductor / ceramic or conductor / conductor. However, this device can apply an external electric field indirectly to achieve the application of an external electric field between non-conductor materials, such as ceramic / ceramic. But it can also directly apply an electric field to conductor materials. When reflected on the external device, applying an electric field to a conductor material: the working electrode / auxiliary electrode is directly connected to the acting component, and the contact position where the acting components move relative to each other needs to be filled with a lubricating fluid; applying an electric field to a non-conductor material such as a ceramic bearing: the working electrode / auxiliary electrode needs to be partially immersed in the lubricating fluid, and the two electrodes need to be installed separately according to the acting surface to achieve solution conduction.

[0029] (6) Improve the reliability of the lubrication system and energy-saving efficiency. This device is a device that provides the external conditions for electro-controlled friction, and its function can adjust the friction coefficient of external devices (such as friction test devices, industrial robot arms, etc.) in real time. Of course, the external industrial device can also be replaced with a friction test device in a university. For the case where the external device is a friction test device, this device can provide an efficient experimental environment. For the case where the external device is more industrialized (such as an industrial robot arm), through real-time regulation during the operation of the external device, accurately controlling the lubrication state and friction behavior can effectively reduce wear and energy loss, improve the operation efficiency and stability of the mechanical system, extend the service life of the external device, and have a significant effect of energy conservation, consumption reduction and maintenance cost reduction.

[0030] (7) Promote the industrialization of electro-controlled friction technology. The present invention provides a systematic solution to the key difficulties (such as limited preparation of lubricating fluid, incompatible control systems, poor stability, etc.) in the actual application of existing electro-controlled friction technologies, and provides a feasible technical platform for its large-scale application in the industrial field.

[0050] Please refer to Figure 7 where the bracket 120 is disposed within the housing 110 and is a multi-layer structure (regarded as a four-layer structure in this embodiment, including a top layer 121, a second layer 122, a third layer 123, and a bottom layer 124). A side bracket 125 is further provided on one side of the bracket 120. When the bracket 120 is disposed within the housing 110, the side bracket 125 is located outside the housing 110 and is used to place some structures (in this embodiment, the side bracket 125 is used to place the workstation 191 of the main control module 190, i.e., a PC).

[0051] Please refer to Figures 2-5 In this embodiment, the base liquid supply module 130 is disposed on the bracket 120 and is used to supply the base liquid. The base liquid can be deionized water for preparing water-based lubricating fluid or base oil for preparing oil-based lubricating fluid. Generally, only one type of base liquid is used in the same device: compound lubricating fluids are compounded from single-component lubricating fluids that all belong to water-based lubricating fluids, or single-component lubricating fluids that all belong to oil-based lubricating fluids.

[0052] The single-component lubricant formulation module 140 is also disposed on the bracket 120 and is connected to the base liquid supply module 130 for formulating and storing at least two types of single-component lubricants.

[0053] Exemplarily, the single-component lubricant formulation module 140 may include at least two sets of single-component lubricant formulation units (two sets of single-component lubricant formulation units are provided in the device of this embodiment, and more sets can be provided in other embodiments to formulate more types of single-component lubricants for realizing the compounding of more complex component compound lubricating fluids). Each set of single-component lubricant formulation units includes a lubricant raw material storage tank 141, a support with a mass monitoring sensor 142, a single-component lubricant formulation tank 143, a solution information detection device 153, and a stirring mechanism 144.

A through hole is opened in the center of the position for the pipeline to pass through), and the mass monitoring sensor communicates with the main control module 190.

[0055] Each lubricant raw material storage tank 141 is disposed on the corresponding support with a mass monitoring sensor 142, and each lubricant raw material storage tank 141 is provided with an automatic control valve that communicates with the main control module 190. Each lubricant raw material storage tank 141 stores lubricant raw materials (surfactants, such as SDS, CTAB, etc.). Of course, the types of lubricant raw materials stored in each lubricant raw material storage tank 141 are different.

[0056] Each single-component lubricant preparation tank 143 is arranged on the second layer 122 of the bracket 120, below the corresponding lubricant base agent storage tank 141, and is communicated with the corresponding lubricant base agent storage tank 141 through a pipeline (the pipeline passes through the through hole opened on the cross frame). In addition, each single-component lubricant preparation tank 143 is also communicated with the base liquid supply module 130 respectively, and the base liquid supply module 130 communicates with the main control module 190. The volume of each single-component lubricant preparation tank 143 is 1-10L.

[0057] Each solution information detection device 153 (which needs to perform temperature detection and concentration detection, can be a temperature and concentration monitor, or can be a separate temperature sensor and concentration sensor) is arranged on the bin wall of the corresponding single-component lubricant preparation tank 143 (if it is a separate temperature sensor and concentration sensor, the temperature sensor and the concentration sensor can be arranged together or separately), and the solution information detection device 153 communicates with the main control module 190, and is used for detecting the concentration information and temperature information during the preparation process of the single-component lubricant in the single-component lubricant preparation tank 143.

[0058] Each stirring mechanism 144 is arranged in the corresponding single-component lubricant preparation tank 143, and is controlled by the main control module 190, and is used for stirring to promote the mutual dissolution of the solution in the single-component lubricant preparation tank 143.

[0059] As Figure 8 shown, each single-component lubricant preparation tank 143 is supported by a stirring motor 1441 with a base, the stirring motor 1441 is fixedly arranged on the second layer 122 of the bracket 120 through the base, the rotating shaft of the stirring motor 1441 is in pin connection with the stirring shaft 1444 in the single-component lubricant preparation tank 143, the stirring shaft 1444 is fixed at the center of the single-component lubricant preparation tank 143 through the bearing 1443 and the bearing seat 1442, the blade 1445 is vertically installed on the stirring shaft 1444, and the rotation of the stirring shaft 1444 is driven by the operation of the stirring motor 1441 to promote the mutual dissolution of the solution in the single-component lubricant preparation tank 143. It should be noted that Figure 8 the cross section in does not show the solution information detection device 153. The rotation speed range of the stirring motor 1441 is 500-1000 rpm.

[0060] In this embodiment, the compound lubricant preparation module 150 is arranged on the bracket 120 and is communicated with the single-component lubricant preparation module 140, and is used for preparing and storing the compound lubricant according to at least two single-component lubricants provided by the single-component lubricant preparation module 140.

Each set of compound lubricating fluid preparation units includes a single-component lubricating fluid supply system 151, a compound lubricating fluid preparation tank 152, a solution information detection device 153, and a high-speed stirring device 154.

[0062] The compound lubricating fluid preparation tank 152 is arranged on the second layer 122 of the bracket 120 and is communicated with each single-component lubricating fluid preparation tank 143 through the single-component lubricating fluid supply system 151. Among them, the single-component lubricating fluid supply system 151 communicates with the main control module 190. To facilitate the fixation of the compound lubricating fluid preparation tank 152, the second layer 122 of the bracket 120 is provided with a limiting structure for the compound lubricating fluid preparation tank 152 (as Figure 7 shown, it is the part fixedly standing on the second layer 122 of the bracket 120. The vacant part of the limiting structure matches the outer shape and size of the compound lubricating fluid preparation tank 152, so as to realize the fixed limit of the compound lubricating fluid preparation tank 152). In this embodiment, the cross-section of the compound lubricating fluid preparation tank 152 is approximately square. Therefore, the vacant part of the limiting structure is also square (as Figure 7 shown). The volume of the compound lubricating fluid preparation tank 152 is 500 - 2000 mL.

[0063] As Figure 9 and Figure 10 shown, the solution information detection device 153 is arranged on the bin wall of the compound lubricating fluid preparation tank 152 and communicates with the main control module 190, and is used to detect the concentration information and temperature information during the preparation process of the compound lubricating fluid in the compound lubricating fluid preparation tank 152. The solution information detection device 153 here is the same as the solution information detection device 153 arranged in the single-component lubricating fluid preparation tank 143, and will not be elaborated here.

[0064] The high-speed stirring device 154 is arranged in the compound lubricating fluid preparation tank 152 and is controlled by the main control module 190, and is used to stir and promote the mutual dissolution of the solutions in the compound lubricating fluid preparation tank 152. The high-speed stirring device 154 is different from the stirring mechanism 144 of the single-component lubricating fluid preparation tank 143. Two stirring structures (high-speed stirring motor 1441, stirring shaft 1444, blades 1445, etc.) are used in a compound lubricating fluid preparation tank 152, and the two stirring structures are arranged separately to improve the compounding efficiency. The rotation speed range of the high-speed stirring motor 1441 is 1000 - 2000 rpm.

[0065] In addition, the compound lubricant preparation tank 152 has a warehouse cover 1521, and a liquid inlet for the single-component lubricant is provided on the warehouse cover 1521. The number of liquid inlets corresponds to the number of single-component lubricant preparation tanks 143. In this embodiment, there are two single-component lubricant preparation tanks 143. Therefore, the number of liquid inlets provided on the warehouse cover 1521 of the compound lubricant preparation tank 152 is also designed to be two, but it should not be regarded as a limitation to this application.

[0066] In order to improve the experimental efficiency in the friction experiment scenario, the number of compound lubricant preparation units is also designed to be two sets, which are arranged together with the single-component lubricant preparation units on the second layer 122 of the bracket 120. In this way, during the process of using one compound lubricant preparation unit to prepare a compound lubricant with a certain concentration for the friction experiment, another compound lubricant preparation unit can be used to prepare a compound lubricant with another concentration, saving the intermediate preparation waiting time and improving the experimental efficiency.

[0067] In the case where the single-component lubricant preparation module 140 includes two sets of single-component lubricant preparation units and the compound lubricant preparation module 150 includes two sets of compound lubricant preparation units, the single-component lubricant supply system 151 includes two sets of single-component lubricant supply units. Each set of single-component lubricant supply units includes a pump, a single-component lubricant supply pipeline, a single-inlet double-outlet electric control valve, and a flow monitor.

[0068] For each set of single-component lubricant supply units:

[0069] One end of the inlet pipeline of the single-component lubricant supply pipeline is communicated with the liquid outlet of the corresponding single-component lubricant preparation tank 143, the other end of the inlet pipeline of the single-component lubricant supply pipeline is communicated with the inlet of the pump, the outlet of the pump is communicated with the inlet of the single-inlet double-outlet electric control valve, and the single-inlet double-outlet electric control valve and the pump are controlled by the main control unit. The flow monitor is arranged at the inlet of the single-inlet double-outlet electric control valve and communicates with the main control module 190; the two outlet pipelines of the single-component lubricant supply pipeline respectively communicate one outlet of the single-inlet double-outlet electric control valve with a compound lubricant preparation tank 152 of a set of compound lubricant preparation units.

[0070] Then, each single-component lubricant supply unit can supply the single-component lubricant in a single-component lubricant preparation tank 143 to two compound lubricant preparation tanks 152. The single-inlet double-outlet electric control valve is controlled by the main control unit and can control which compound lubricant preparation tank 152 the single-component lubricant is supplied to, realizing the supply of the single-component lubricant. The flow monitor monitors the flow rate, and combined with the single-inlet double-outlet electric control valve, precise supply of the single-component lubricant can be achieved.

[0071] Please refer to Figures 2-5, the base liquid supply module 130 includes a base liquid storage tank 131 (a base liquid replenishment port 1311 is provided at the top of the base liquid storage tank 131, which can facilitate the addition of base liquid) and a base liquid supply system 132. The base liquid supply system 132 includes the corresponding number of base liquid supply units according to the number of sets of the single-component lubricant preparation units. The base liquid storage tank 131 is arranged on the bottom layer 124 of the bracket 120 and is used to store the base liquid (the base liquid is base oil or deionized water).

[0072] Each set of base liquid supply units is respectively connected to the base liquid storage tank 131 and the corresponding single-component lubricant preparation tank 143, and communicates with the main control unit, and is used to accurately supply the base liquid to the corresponding single-component lubricant preparation tank 143.

[0073] Exemplarily, each set of base liquid supply units includes a pump, a connecting pipe 1321, a base liquid supply pipe 1322, an electronic flow controller, and a six-nozzle annular pipe 1323.

[0074] The inlet of the pump is connected to the base liquid storage tank 131 through the connecting pipe 1321, the outlet of the pump is connected to the base liquid supply pipe 1322, and the base liquid supply pipe 1322 is further connected to the six-nozzle annular pipe 1323; the electronic flow controller is arranged at the connection between the base liquid supply pipe 1322 and the six-nozzle annular pipe 1323 and communicates with the main control unit, and is used to accurately control the supply amount of the base liquid. Six-nozzle annular pipe interfaces connected to the six-nozzle annular pipe 1323 are provided around the top side of the single-component lubricant preparation tank 143, and the six-nozzle annular pipe 1323 is connected to the six-nozzle annular pipe interfaces for evenly supplying the base liquid into the single-component lubricant preparation tank 143.

[0075] The liquid inlet of the six-nozzle annular pipe 1323 is one, and the liquid outlets are six, which are arranged at equal intervals along the ring. The aperture of the liquid outlet close to the liquid inlet is smaller than the aperture of the liquid outlet far from the liquid inlet (the aperture size decreases in a gradient with its distance from the liquid inlet) to keep the liquid outlet as uniform as possible. Of course, a laminar flow induction structure (such as a perforated plate or a honeycomb rectifier, which needs to be designed to corresponding dimensions and arranged in the six-nozzle annular pipe 1323) can also be designed in the six-nozzle annular pipe 1323 to make the hydraulic pressure in the six-nozzle annular pipe 1323 tend to be balanced, and the aperture of each liquid outlet can be the same, and the liquid outlet can also be kept uniform. For the friction experiment scenario in the laboratory, the requirement for such uniform liquid outlet is not high, but for the industrial scenario, such a requirement is very likely to exist, and the six-nozzle annular pipe 1323 can be prepared according to the above design method to make it uniformly discharge liquid to meet the requirements of the industrial scenario.

[0076] Please refer to Figures 1-5 , the compound lubricant disposal module 160 may include a compound lubricant supply unit 161, a liquid supply nozzle 162, a flushing unit 163, a flushing nozzle 164, a sewage suction unit 165, a sewage suction nozzle 166, and a waste liquid tank 167.

[0077] The liquid supply nozzle 162 is connected to the compound lubricant preparation tank 152 through the compound lubricant supply unit 161. The compound lubricant supply unit 161 is controlled by the main control unit and is used to supply the compound lubricant to an external friction experiment device through the liquid supply nozzle 162.

[0078] Exemplarily, when the compound lubricant preparation module 150 includes two sets of compound lubricant preparation units, the compound lubricant supply unit 161 includes a liquid supply connection pipeline, a double-in single-out electric control valve, two compound lubricant supply pipelines, two pumps, and two flow monitors. The inlet of each pump is respectively connected to a compound lubricant preparation tank 152 through a compound lubricant supply pipeline, the outlet of each pump is respectively connected to an inlet of the double-in single-out electric control valve, the outlet of the double-in single-out electric control valve is connected to the liquid supply nozzle 162 through the liquid supply connection pipeline, each pump is controlled by the main control unit, and the double-in single-out electric control valve is controlled by the main control unit; each flow monitor is respectively arranged at the connection between its corresponding pump and the double-in single-out electric control valve, and each flow monitor communicates with the main control unit. Then, first, the two compound lubricant supply units 161 can respectively extract the compound lubricant from the corresponding compound lubricant preparation tanks 152 and flow out from the liquid supply nozzle 162 (of course, each time the compound lubricant is supplied, the main control unit needs to control which compound lubricant preparation tank 152 to extract the compound lubricant from for supply, rather than supplying simultaneously). Then, the compound lubricant can be provided to an external friction experiment device through the liquid supply nozzle 162 for friction experiments.

[0079] The flushing nozzle 164 is connected to the base liquid storage tank 131 through the flushing unit 163. The flushing unit 163 is controlled by the main control unit and is used to perform flushing with the base liquid through the flushing nozzle 164.

[0080] Exemplarily, the flushing unit 163 can include a base liquid connection pipeline, a control valve, a pump, and a base liquid supply pipeline. The inlet of the pump is connected to the base liquid storage tank 131 through the base liquid supply pipeline. The control valve is arranged at the outlet of the base liquid storage tank 131 opened and connected to the base liquid supply pipeline. The outlet of the pump is connected to the flushing nozzle 164 through the base liquid connection pipeline, and then flushing can be performed with the base liquid through the flushing nozzle 164.

[0081] The waste liquid tank 167 is arranged at the bottom layer 124 of the bracket 120. The sewage suction nozzle 166 is connected to the waste liquid tank 167 through the sewage suction unit 165. The sewage suction unit 165 is controlled by the main control unit and is used to suck the waste liquid into the waste liquid tank 167 through the sewage suction nozzle 166.

[0082] Exemplarily, the sewage suction unit 165 may include a sewage suction connecting pipe, a vacuum pump, and a waste liquid recovery pipe. The sewage suction nozzle 166 is communicated with the inlet of the vacuum pump through the sewage suction connecting pipe, and the outlet of the vacuum pump is communicated with the waste liquid tank 167 (the connection port is arranged at the top of the waste liquid tank 167) through the waste liquid recovery pipe, so as to recover the waste liquid into the waste liquid tank 167 through the sewage suction nozzle 166.

[0083] Exemplarily, a sewage discharge port 1671 is provided at the bottom of each compound lubricant preparation tank 152. A sewage discharge valve is provided at the sewage discharge port 1671, and the sewage discharge valve is controlled by the main control unit. The sewage discharge port 1671 is communicated with the waste liquid tank 167 through a sewage discharge pipe. Since the compound lubricant preparation tank 152 is arranged on the second layer 122 of the bracket 120, and the waste liquid tank 167 is arranged on the bottom layer 124 of the bracket 120, natural sewage discharge can be realized through the height difference. Of course, a sewage discharge port 1671 can also be provided at the bottom of the single-component lubricant preparation tank 143, and the sewage discharge method is similar to that of the compound lubricant preparation tank 152.

[0084] A waste liquid discharge port is opened below the waste liquid tank 167, which is convenient for connecting to the sewage pipe for treatment.

[0085] Please refer to Figures 1-5 , the external voltage module 180 for friction experiments may include a regulated power supply 181, a working electrode 182 (the end is designed as a hook shape for convenient connection and cooperation with various friction pairs), and an auxiliary electrode 183 (the end is designed as a sheet shape for convenient immersion in the lubricant). The regulated power supply 181 is arranged on the third layer 123 of the bracket 120 and is connected to the main control unit; the working electrode 182 is connected to the positive output port of the regulated power supply 181 through a power wire; the auxiliary electrode 183 is connected to the negative output port of the regulated power supply 181 through a power wire. The voltage output range of the external voltage module 180 for friction experiments is -100V to +100V, and the voltage regulation accuracy is ±0.001V, which is used to generate a programmable electric field on the surface of the friction pair.

[0086] The main control module 190 may include a workstation 191 and a display screen 192. The workstation 191 is arranged on the side frame 125 of the bracket 120, and the display screen 192 is embedded on the housing 110 and is connected to the workstation 191. The workstation 191 can communicate with automation platforms such as PLC and DCS, and has functions of remote control, data recording, parameter self-learning and feedback optimization. The modular solution preparation and electric control friction regulation integrated device 100 is applicable to the friction interface of conductive or non-conductive friction pair materials, and realizes continuous adjustment and adaptive control of friction performance under dynamic load, variable speed motion and micro-scale working conditions.

[0087] The above is a detailed introduction to the structural design of the modular solution preparation and electro-controlled friction regulation integrated device 100. Here, the operating principle of the modular solution preparation and electro-controlled friction regulation integrated device 100 will be introduced in combination with its operating process.

[0088] The modular solution preparation and electro-controlled friction regulation integrated device 100 provided in this embodiment, its overall system mainly includes a base liquid supply module 130, a single-component lubricant preparation module 140, a compound lubricant preparation module 150, a compound lubricant disposal module 160, a real-time monitoring module 170, a friction experiment external voltage module 180, a main control module 190, etc. Through unified control by the main control module 190 (PC host), integrated operations such as high-precision preparation of lubricants, real-time monitoring, electro-controlled friction adjustment, and intelligent feedback optimization are realized.

[0089] For example, taking an anionic surfactant (such as SDS) as material A (stored in the lubricant raw material storage tank A) and a cationic surfactant (such as CTAB) as material B (stored in the lubricant raw material storage tank B) as an example, the specific working process of the device is as follows:

[0090] First, enter the key parameters of the required compound lubricant on the display screen 192 interface of the PC host (i.e., the main control module 190), including the target ratio of material A to material B (such as SDS:CTAB = 7:1), the total concentration (such as 0.5 mM), the target volume (such as 1000 mL), the stirring speed, and the voltage required for the experiment, etc. After receiving the setting instruction, activate the single-component lubricant preparation module 140, open the automatic control valves of the lubricant raw material storage tank A and the lubricant raw material storage tank B, and under the precise measurement of the quality monitoring sensor, sequentially release particles (or stock solution) quantitatively into the single-component lubricant preparation tank C and the single-component lubricant preparation tank D. Subsequently, through the base liquid supply module 130, inject a set volume of base liquid (deionized water or base oil) evenly into the single-component lubricant preparation tank C and the single-component lubricant preparation tank D through the base liquid supply unit (including a pump, a connecting pipe 1321, a base liquid supply pipe 1322, an electronic flow controller, a six-nozzle annular pipe 1323). After the base liquid injection is completed, the stirring motor 1441 starts, driving the stirring shaft 1444 and the blades 1445 to rotate, ensuring the full dissolution of material A in the base liquid in the single-component lubricant preparation tank C (and, the full dissolution of material B in the base liquid in the single-component lubricant preparation tank D), forming a single-component lubricant C with uniform concentration (in the single-component lubricant preparation tank C) and a single-component lubricant D (in the single-component lubricant preparation tank D).

[0091] After the single-component liquid is prepared, the PC host computer (i.e., the main control module 190) controls the single-component lubricating liquid supply system 151 (two sets of single-component lubricating liquid supply units, each single-component lubricating liquid supply unit includes a pump, a single-component lubricating liquid supply pipeline, a single-inlet and double-outlet electronic control valve, and a flow monitor), and respectively transports the single-component lubricating liquid C and the single-component lubricating liquid D to the compound lubricating liquid preparation tank 152E according to a preset ratio (if the number of compound lubricating liquid preparation tanks 152 is 2, after the supply of the single-component lubricating liquid C and the single-component lubricating liquid D to the compound lubricating liquid preparation tank E is completed, the single-component lubricating liquid supply system 151 can also be controlled to transport the single-component lubricating liquid C and the single-component lubricating liquid D to the compound lubricating liquid preparation tank F according to another set ratio). The PC host computer controls the corresponding high-speed stirring motor 1441 to start, and the blades 1445 rotate at a high speed to achieve full compounding of the mixed solution in the compound lubricating liquid preparation tank E (or the compound lubricating liquid preparation tank F). At the same time, the solution information detection device 153 (such as a concentration and temperature monitor) installed on the bin wall monitors the concentration and temperature changes of the compound lubricating liquid in real time, and feeds back the data to the PC host computer in real time. If there is a deviation between the detected value and the target value, the main control module 190 automatically adjusts the flow rates of each component to achieve dynamic concentration correction and ensure the accuracy and stability of the compound lubricating liquid.

[0092] After the compounding of the compound lubricating liquid is completed, the compound lubricating liquid in the compound lubricating liquid preparation tank E (or the compound lubricating liquid preparation tank F) is transported to the friction action equipment end (i.e., the friction experiment device) via the compound lubricating liquid supply unit 161 through the liquid supply nozzle 162, and the electro-controlled friction test is ready to be carried out. At this time, the operator installs the working electrode 182 and the auxiliary electrode 183 to the predetermined positions. The working electrode 182 is in direct contact with the friction interface, while the auxiliary electrode 183 needs to be immersed (or semi-immersed) in the compound lubricating liquid of the friction experiment device. The PC host computer controls the regulated power supply 181 of the friction experiment external voltage module 180 to output a set voltage (such as +10V), and connects to the two electrodes respectively through the power supply wires to establish a stable electric field at the friction interface. The external electric field induces the ordered adsorption of charged molecules in the lubricating liquid, thereby regulating the molecular structure and lubrication performance of the friction interface.

[0093] During the experiment, the real-time detection module continuously monitors key data such as the energy consumption of the friction experiment device, and transmits the results to the PC host computer. The PC host computer dynamically adjusts the electric field strength according to the feedback information to achieve closed-loop control and ensure the accuracy and stability of friction regulation.

[0094] After the experiment is completed, start the sewage suction unit 165 in the lubricant disposal module. Under the action of a vacuum pump, the residual lubricant is pumped into the waste liquid tank 167 through the sewage suction nozzle 166. Subsequently, the base liquid in the base liquid storage tank 131 is pumped out through the flushing nozzle 164 via the flushing unit 163 to clean the friction experiment device (the experimental part, i.e., the friction pair part) and related pipelines, ensuring that the friction experiment device is in a clean state before the next experiment.

[0095] During the whole process of preparing the compound lubricant and the friction experiment process, various sensors (temperature, flow rate, concentration, etc.) monitor the lubricant concentration, temperature, and the energy consumption data of the acting equipment (i.e., the friction experiment device) in real time, and feed the information back to the PC host. As the control center, the PC host comprehensively analyzes various data and then controls the friction experiment external voltage module 180 to dynamically apply an electric field between the working electrode 182 and the auxiliary electrode 183, thereby regulating the adsorption behavior of lubricating molecules at the friction interface and achieving precise regulation of friction performance. The double-electrode electro-controlled friction system composed of the working electrode 182, the auxiliary electrode 183, and the compound lubricant. The two electrodes (the working electrode 182 and the auxiliary electrode 183) are respectively arranged around the moving parts of the acting equipment to provide a stable electric field for regulating the adsorption behavior of lubricant molecules at the friction interface. Through the real-time energy consumption feedback information of the acting equipment, the friction and wear and other information at the moving parts can be understood in real time. The PC host judges and controls the magnitude of the applied voltage value in real time according to the feedback information to achieve precise regulation and dynamic optimization of friction performance. The double-electrode system here: includes the working electrode 182 (WE) and the auxiliary electrode 183 (CE). The working electrode 182 is in direct contact with the friction pair of the friction experiment device (i.e., the moving parts of the acting equipment), and directly regulates the molecular behavior of the lubricating interface through the electric field; the auxiliary electrode 183 is wholly or partially immersed in the compound lubricant at that place. Each module of the entire equipment constitutes an intelligent closed-loop process of "preparation → action → monitoring → feedback → regulation → optimization", with the technical advantages of high integration, high responsiveness, and strong scalability, and is applicable to the dynamic adjustment and optimization of the friction performance of various conductor and non-conductor friction pair materials under complex working conditions.

[0096] The following further illustrates this embodiment with several examples:

[0097] Example 1:

[0098] Experiments on the electric field-regulated friction performance were carried out using aqueous solutions prepared by mixing anionic surfactant (SDS) and cationic surfactant (CTAB) at different concentrations as water-based lubricants. The solution concentrations were 0.5 mM, 1.0 mM, 2.0 mM, and 4.0 mM in sequence, and the mixing ratios of anionic and cationic surfactants were 7:1, 3:1, and 1:0, respectively. It was found that the introduction of CTAB expanded the applicable concentration range of SDS lubricants in the electro-controlled friction system, and the mixed system was overall superior to the single-component system in terms of friction performance regulation. Under low-concentration conditions (c ≤ 1.0 mM, mixing ratio 7:1), significant electro-controlled friction performance was exhibited, achieving wide-range regulation and rapid response of the friction coefficient; while under high-concentration conditions (c ≥ 4.0 mM), the system as a whole showed a higher electric field response rate. The experimental results at total concentrations of 0.5 mM and 4.0 mM are shown as Figure 11 and Figure 12 shown.

[0099] Example 2:

[0100] Experiments on the electric field-regulated friction performance were carried out using solutions prepared by mixing ionic liquids with anti-wear substances ZDDP and MoDTC at different concentrations as oil-based lubricants. The mass fraction of the ionic liquid was 1.0 wt%; the mass fraction of ZDDP was 0.5 wt%; the mass fraction of MoDTC was 0.5 wt%. It was found that the lubrication effect was poor when only the ionic liquid was added to the base oil. However, if a solution prepared by mixing ZDDP or MoDTC with the ionic liquid was added, the lubrication effect was better. At the same time, it was found that the electro-controlled effects were all relatively obvious, as Figure 13 shown.

[0101] In summary, the embodiment of the present application provides an integrated device 100 for modular solution preparation and electro-controlled friction regulation, which supplies base liquid through the base liquid supply module 130, uses the single-component lubricant preparation module 140 to prepare and store at least two single-component lubricants, and then uses the compound lubricant preparation module 150 to prepare and store compound lubricant according to at least two single-component lubricants provided by the single-component lubricant preparation module 140. The compound lubricant disposal module 160 supplies the compound lubricant prepared by the compound lubricant preparation module 150 to an external friction experiment device, and is used to extract residual liquid and clean it after the friction experiment; the real-time monitoring module 170 collects experimental data (including the energy consumption information of the external friction experiment device) during the friction experiment of the external friction experiment device, designs the external voltage module 180 for the friction experiment, and generates a stable electric field during the friction experiment of the external friction experiment device to regulate the interfacial behavior of the compound lubricant molecules; the main control module 190 receives the experimental data collected by the real-time monitoring module 170, adjusts the electric field intensity of the external voltage module 180 for the friction experiment according to the experimental data, and is used to control the ratio and flow rate in the whole process of compound lubricant preparation (including the single-component lubricant preparation process and the compound lubricant preparation process). Through highly integrated and highly modular design, the present invention integrates multiple functional modules such as lubricant preparation, voltage control, friction testing, data acquisition and feedback control, overcomes the defects of scattered structure and cumbersome operation in the electro-controlled friction experiment of traditional equipment, realizes "integrated operation and closed-loop control", and significantly improves the system stability and experimental / engineering efficiency.
