Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lubricating oil treatment, in particular to an intelligent oil treatment method, system, device and storage medium. BACKGROUND

[0002] In industrial equipment such as large gearboxes, bearings, hydraulic systems, etc., lubricating oil plays a crucial role in lubrication, cooling, cleaning, rust prevention, etc. The quality of lubricating oil is directly related to the operating efficiency, service life and safety of the equipment. However, during long-term use, lubricating oil will deteriorate due to oxidation and contamination, the main problems include: viscosity increase or emulsification caused by low temperature or water intrusion, increased impurities caused by metal debris or external contaminants, and water mixed in due to condensation or leakage.

[0003] In the prior art, separate devices are usually used to handle these problems, such as using an online heater to reduce viscosity, using a filter to remove particulate matter, and using a centrifuge or vacuum dewatering device to separate water. However, these devices often work independently, have low integration, and require manual switching and operation based on oil condition, which results in low oil treatment efficiency, high energy consumption, and reliance on human experience, making it impossible to achieve precise, efficient, and fully automatic oil maintenance, so there is room for improvement SUMMARY

[0004] In order to improve the efficiency of oil treatment and achieve precise, efficient and fully automatic oil maintenance, the present application provides an intelligent oil treatment method, system, device and storage medium.

[0005] In a first aspect, the present application provides an intelligent oil treatment method, which adopts the following technical solution:

[0006] Receiving an oil line switching instruction, switching the oil line to the oil line contained in the oil line switching instruction, and determining the current oil treatment mode, wherein different oil treatment modes correspond to different oil lines, and each oil line is provided with a corresponding treatment unit for treating lubricating oil;

[0007] According to the current oil treatment mode, a preset control strategy corresponding to the current oil treatment mode is called;

[0008] Executing the control strategy and dynamically adjusting the working parameters of the treatment unit in the current oil treatment mode based on the control strategy and the real-time monitoring of the oil line treatment state;

[0009] Wherein, the oil treatment mode at least includes:

[0010] Single heating mode, the treatment unit provided in the oil line includes a heating unit for heating lubricating oil;

[0011] The heating and impurity removal mode corresponds to the processing unit arranged in the oil circuit, and the processing unit comprises a heating unit and an impurity removal unit for filtering and removing impurities from the lubricating oil.

[0012] The heating, impurity removal and water removal mode corresponds to the processing unit arranged in the oil circuit, and the processing unit comprises a heating unit, an impurity removal unit, and a water removal unit for removing water from the lubricating oil.

[0013] By adopting the technical scheme, the corresponding processing unit is arranged for each oil circuit to form a corresponding oil processing mode, and a set of special control strategies is matched for each oil processing mode, that is, not only the switching control of the lubricating oil flow path is realized, but also different oil processing modes are executed by switching the physical oil circuit, and in the processing process, the working parameters of the processing unit are controlled according to the real-time monitored oil processing state, the efficient, intelligent and fine processing control of the lubricating oil is realized, the dependence on the experience of the operator is greatly reduced, and the stability and reliability of the processing result are ensured.

[0014] Optionally, the control strategy is executed, and the working parameters of the processing unit in the current oil processing mode are dynamically adjusted based on the control strategy and the oil circuit processing state obtained in real time, and the working parameters of the processing unit in the current oil processing mode are dynamically adjusted based on the control strategy and the oil circuit processing state obtained in real time.

[0015] When the current oil processing mode is the single heating mode, real-time oil circuit temperature data is obtained, and the start-stop number of the preset heating unit is controlled.

[0016] When the current oil processing mode is the heating and impurity removal mode, the start-stop number of the preset heating unit is controlled according to the real-time oil circuit temperature data; and whether the filter element of the impurity removal unit needs to be replaced is determined and output according to the oil circuit pressure difference data at the inlet and outlet of the impurity removal unit, so that the worker can know.

[0017] When the current oil processing mode is the heating, impurity removal and water removal mode, the start-stop number of the preset heating unit is controlled according to the real-time oil circuit temperature data; whether the filter element of the impurity removal unit needs to be replaced is determined and output according to the oil circuit pressure difference data at the inlet and outlet of the impurity removal unit, so that the worker can know; and the opening and closing of the drain valve for draining the water in the water removal unit is controlled according to the water content data in the water removal unit.

[0018] By adopting the technical scheme, the specific control strategy corresponding to each oil processing mode is described in detail, that is, the working parameters of the processing unit are dynamically adjusted by using monitoring data (such as oil circuit temperature data, pressure difference data and water content data), and the processing precision of the processing unit to the oil circuit is indirectly ensured.

[0019] Optionally, a first branch for realizing cross-oil circuit communication is arranged between different oil circuits, and a first branch valve for controlling whether the first branch communicates is installed on the first branch.

[0020] The method further comprises:

[0021] When a fault unit exists in the current oil circuit corresponding to the current oil processing mode, the current oil circuit is divided into an available section and an isolated section according to the position of the fault unit in the current oil circuit, and the communication between the available section and the isolated section is cut off; wherein the available section refers to a section in the circuit before the lubricating oil flows to the fault unit and does not contain the fault unit, and the isolated section refers to a section from the fault unit to the oil circuit outlet in the current circuit;

[0022] The oil circuit containing the isolated section is screened out from other oil circuits except the current oil circuit as an available oil circuit, and a section in the available oil circuit which is the same as the processing unit contained in the isolated section is taken as a target section;

[0023] A first branch valve of a first branch between the available section corresponding to the current oil processing mode and the available oil circuit is controlled to communicate the target section and the available section in the current oil circuit to form an obstacle-avoiding oil circuit, and the lubricating oil is transmitted by using the obstacle-avoiding oil circuit.

[0024] By adopting the above technical solution, since there are common processing units between different oil processing modes, if the common processing unit fails, the section (i.e. the target section) in which the processing unit with the same function as the failed processing unit is located in other oil circuits is used to replace the failed processing unit, to help complete the function of the failed processing unit, break the waste of resources caused by “one oil processing mode fixedly occupying one complete oil circuit”, change the processing units of the whole system into a resource pool that can be flexibly called, and realize on-demand allocation and maximum utilization of hardware resources; at the same time, the system flexibility and application range are greatly improved, although the initial valve and pipeline investment is slightly high, but overall, the cost-effectiveness is higher, because the time loss caused by downtime maintenance of the fault unit is reduced.

[0025] Optionally, each oil circuit is further provided with a second branch and a second communication valve; the second branch has a parallel relationship with a designated processing unit in the oil circuit, and the parallel relationship refers to that the inlet and outlet of the second branch are the same as the inlet and outlet of the corresponding processing unit; the second communication valve is located at the inlet and outlet of the second branch with the associated relationship, so that at the same time, the lubricating oil can only flow through one of the second branch or the processing unit;

[0026] The method further comprises:

[0027] When the current oil processing mode meets the multi-path parallel processing condition, according to the processing unit contained in the current oil circuit corresponding to the current oil processing mode, a parallel path segment is generated by using the processing unit shared by the current oil circuit and other oil circuits, and the oil circuit containing the available path segment is selected from all oil circuits as a parallel oil circuit;

[0028] The communication of the second branch in each of the parallel oil circuits is controlled, so that the oil processing mode of the oil circuit through which each of the parallel oil circuits flows is exactly the same as the oil processing mode of the current oil circuit, and the current oil circuit and the parallel oil circuit are used to synchronously transmit lubricating oil.

[0029] By adopting the above technical scheme, the present scheme utilizes the processing unit shared by different oil processing modes and the second branch to enable the lubricating oil to "bypass" the processing unit associated with the second branch without enabling the processing operation of the corresponding processing unit, and the second branch is used to realize the assimilation processing of multiple oil circuits, so that the same oil processing mode can be executed in parallel by using multiple oil circuits, thereby finally realizing the flexible expansion of the oil processing capacity and extremely improving the efficiency. The "dynamic reconstruction" of the previous scheme is combined with the "parallel replication" of the present scheme, and the entire system is no longer composed of several fixed-function oil circuits, but evolves into a unified and flexible scheduling computing resource pool.

[0030] Optionally, the method further comprises:

[0031] The cumulative working time length of each impurity removal unit, the cumulative processing oil volume in the cumulative working time length, and the change rate of the pressure difference value of the pipeline between the inlet and outlet of the impurity removal unit are recorded in real time;

[0032] The maintenance time of the impurity removal unit is output in real time according to the change rate of the pressure difference value of the pipeline, so that the worker can know;

[0033] When the time difference between the current time and the maintenance time is less than the preset warning time difference, the corresponding impurity removal unit is determined as a fault unit.

[0034] By adopting the above technical scheme, the remaining processing oil volume is predicted based on the relationship between the pressure difference and the cumulative oil volume, and the maintenance time is predicted based on the relationship between the cumulative oil volume and the cumulative working time length, so as to help the worker to know the maintenance time of the processing unit in advance and help to plan the obstacle avoidance path in advance.

[0035] Optionally, the method further comprises:

[0036] The initial temperature of the lubricating oil flowing into the oil circuit and the preset ideal temperature are obtained in real time, the pumping speed of the lubricating oil is determined in real time, and the lubricating oil is input into the current oil circuit according to the real-time determined pumping speed.

[0037] By using the above technical scheme, the pumping speed is calculated in advance according to the initial temperature of the lubricating oil, the heating time is prolonged by reducing the pumping speed, so that the temperature of the lubricating oil can be raised to the ideal temperature, and the rapidity of the feedforward and the accuracy of the feedback are combined, so that the temperature fluctuation can be significantly reduced, and the oil temperature can be stabilized in a very narrow range.

[0038] Optionally, the method further comprises:

[0039] The running state of each oil circuit and the flow path of the current lubricating oil are displayed, and the running state at least includes the on-off state of each processing unit in the oil circuit.

[0040] By using the above technical scheme, the flow path of the current lubricating oil in all oil circuits and the working state of each processing unit in each oil circuit are displayed intuitively.

[0041] In a second aspect, the application provides an intelligent oil processing system, comprising,

[0042] A switching instruction receiving module is configured to receive an oil circuit switching instruction, switch the oil circuit to an oil circuit included in the oil circuit switching instruction, and determine a current oil processing mode, wherein different oil processing modes correspond to different oil circuits, and each oil circuit is provided with a corresponding processing unit for processing lubricating oil;

[0061] The following will be described in combination with the drawingsFigures 1-6 The application is described in further detail.

[0062] Embodiments of the application disclose an intelligent oil treatment method, and a corresponding execution subject is an intelligent oil treatment system (hereinafter referred to as a treatment system). The specific flow steps of the intelligent oil treatment method of the treatment system are described below in combination with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 .

[0063] S101, receiving an oil path switching instruction, switching the oil path to an oil path contained in the oil path switching instruction, and determining a current oil treatment mode, wherein different oil treatment modes correspond to different oil paths, and each oil path is provided with a corresponding treatment unit for treating lubricating oil.

[0064] S102, according to the current oil treatment mode, calling a preset control strategy corresponding to the current oil treatment mode.

[0065] S103, executing the control strategy, and dynamically adjusting the working parameters of the treatment unit in the current oil treatment mode based on the control strategy and the oil path treatment state obtained by real-time monitoring;

[0066] wherein the oil treatment mode at least includes:

[0067] a single heating mode, the treatment unit provided in the oil path includes a heating unit for heating the lubricating oil;

[0068] a heating and impurity removal mode, the treatment unit provided in the oil path includes a heating unit and an impurity removal unit for filtering and removing impurities from the lubricating oil;

[0069] a heating, impurity removal and water removal mode, the treatment unit provided in the oil path includes a heating unit, an impurity removal unit, and a water removal unit for removing water from the lubricating oil.

[0070] and S103 specifically includes the following steps:

[0071] when the current oil treatment mode is the single heating mode, obtaining real-time oil path temperature data, and controlling the start-stop number of a plurality of preset heating units;

[0072] when the current oil treatment mode is the heating and impurity removal mode, according to the real-time oil path temperature data, controlling the start-stop number of a plurality of preset heating units; according to the oil path pressure difference data of the inlet and outlet of the impurity removal unit, determining and outputting the determination result of whether to replace the filter element of the impurity removal unit, for the worker to know;

[0073] When the current oil treatment mode is the heating, impurity removal and water removal mode, the number of heating units to be started or stopped is controlled according to real-time oil line temperature data; whether the filter element of the impurity removal unit needs to be replaced is determined and output according to the pressure difference data of the oil line at the inlet and outlet of the impurity removal unit, so as to be known by the staff; and the opening and closing of the drain valve for draining the water in the water removal unit is controlled according to the water content data in the water removal unit.

[0074] In implementation, the oil line switching instruction can be manually triggered by the staff, such as selecting the oil treatment mode to be switched on the preset touch display screen, so as to trigger the oil line switching instruction. After receiving the oil line switching instruction, the processing system determines the corresponding oil line, the current oil treatment mode and the control strategy according to the preset corresponding relationship table (i.e. for storing different oil lines, the oil treatment mode corresponding to each oil line, and the control strategy corresponding to each oil treatment mode).

[0075] Among them, since the switching of the oil line is generally realized by adjusting the opening and closing of the valve (such as a three-way valve) preset in the oil line, the different oil lines can be distinguished and described by the opening and closing state of the corresponding valve. For example, if the first valve is opened and the second valve is closed when switching to a certain oil line, the description of "the first valve is open, and the second valve is closed" can be used to describe this oil line. Then the processing system adjusts the opening and closing of the corresponding valve according to the valve state described by the corresponding oil line, and realizes the switching of the oil line.

[0076] When the current oil treatment mode is the single heating mode, the heater H1 (i.e. heating unit) is configured in the corresponding oil line A for heating the lubricating oil flowing through the oil line. In addition, two heating units H1-1 and H1-2 are preset in the oil line, and each heating unit H1 is respectively configured with a temperature sensor for monitoring the temperature of each heating unit H1. The temperature data of the two corresponding heating units H1 are CT1-1 and CT1-2 respectively. The oil line A is also provided with a temperature sensor for monitoring the temperature of the pipeline of the oil line (i.e. oil line temperature data), and the corresponding temperature data is marked as CT2. Correspondingly, the flow direction of the lubricating oil in the oil line A can be represented as: oil pump P1→heating unit H1-1→heating unit H1-2→outlet. The corresponding control strategy can refer to Figure 2, if CT2≤T1, then two heating units are opened and the oil pump is started, if T1

[0077] When the current oil processing mode is the heating and impurity removal mode, the oil circuit B corresponding thereto contains the heating units H2-1 and H2-2 and the temperature sensors which are configured in the same way as in the single heating mode, and further contains the impurity removal units F1 (such as mechanical filters). The heating units and the impurity removal units F1 are sequentially arranged along the flow direction of the lubricating oil, so that the lubricating oil is first heated and then filtered and impurity-removed by the impurity removal units F1. In addition, the oil circuit B further contains pressure sensors arranged on the inlet and outlet pipelines of each impurity removal unit F1, for detecting the pressure data CP1 at the corresponding pipelines. The processing system can use the pressure data detected by the pressure sensors on the inlet and outlet pipelines of each impurity removal unit F1 to obtain the oil circuit pressure difference data ΔP1 and ΔP2 of the corresponding impurity removal unit. Correspondingly, the flow direction of the lubricating oil in the oil circuit B can be represented as: oil pump P1→heating unit H2-1→heating unit H2-2→impurity removal unit F1→outlet. The control logic corresponding to the heating and impurity removal mode contains the control logic corresponding to the single heating mode, and further contains the logic content shown in FIG. 6: Figure 3 When the pressure data CP1 is greater than P1, a high-pressure alarm signal is output, and when the pressure data CP1 is less than P2, a low-pressure alarm signal is output, for the worker to know. When the oil circuit pressure difference data ΔP1 and / or ΔP2 is greater than a preset first difference value, it is considered that the filter element of the corresponding impurity removal unit is blocked, and at this time, a blockage alarm signal of the corresponding impurity removal unit is output, for the worker to know, so as to replace the filter element of the impurity removal unit. Wherein P1 is greater than P2.

[0078] When the current oil treatment mode is the heating, impurity removal and water removal mode, the oil circuit C includes the same treatment units and sensors as the oil circuit B corresponding to the heating and impurity removal mode, and further includes a water removal unit W (such as a water removal filter) for water removal treatment of the lubricating oil, and a pressure sensor arranged on the inlet and outlet pipes of the water removal unit for detecting pressure data CP2 at the corresponding pipes. The processing system can use the pressure data detected by the pressure sensor on the inlet and outlet pipes of the water removal unit to obtain oil circuit pressure difference data △P3 of the water removal unit. A liquid level sensor is further arranged in the water removal unit for detecting water content data CL in the water removal unit. Correspondingly, the flow direction of the lubricating oil in the oil circuit C can be represented as: oil pump P1→heating unit H3-1→heating unit H3-2→impurity removal unit F2→water removal unit W→outlet. The control logic corresponding to the heating, impurity removal and water removal mode includes the control logic of the heating and impurity removal mode, and the logic content shown in Figure 4 When the oil circuit pressure difference data △P3 is greater than a preset second difference value, it is considered that the filter element of the water removal unit is blocked, and a water removal unit blockage alarm signal is outputted for the staff to know. When the water content data CL of the water removal unit is greater than L3, a high liquid level alarm signal is outputted. If L2

[0079] Optionally, referring to the oil circuit network shown in Figure 5 The first branch for realizing cross-circuit communication is arranged between different oil circuits, and a first branch valve for controlling the communication of the first branch is arranged on the first branch. Each oil circuit is further provided with a second branch and a second communication valve. The second branch has a parallel relationship with a designated treatment unit in the oil circuit, and the parallel relationship means that the inlet and outlet of the second branch are the same as those of the corresponding treatment unit. The second communication valve is located at the inlet and outlet of the second branch having the associated relationship, so that at the same time, the lubricating oil can only flow through one of the second branch or the treatment unit.

[0080] The corresponding intelligent oil treatment method further includes the following steps:

[0081] When there is a fault unit in the current oil circuit corresponding to the current oil treatment mode, the current oil circuit is divided into an available section and an isolated section according to the position of the fault unit in the current oil circuit, and the communication between the available section and the isolated section is cut off. The available section refers to a section in the circuit before the lubricating oil flows to the fault unit and does not include the fault unit, and the isolated section refers to a section in the current circuit from the fault unit to the outlet of the oil circuit.

[0082] The oil path containing the isolation section is screened out from other oil paths except the current oil path as an available oil path, and the same section as the processing unit contained in the isolation section in the available oil path is taken as a target section;

[0083] The first branch valve of the first branch between the available section corresponding to the current oil processing mode and the available oil path is controlled to communicate the target section and the available section in the current oil path to form an obstacle-avoiding oil path, and the lubricating oil is transmitted by using the obstacle-avoiding oil path.

[0084] When the current oil processing mode meets the multi-path parallel processing condition, according to the processing unit contained in the current oil path corresponding to the current oil processing mode, the parallel section is generated by using the processing unit shared by the current oil path and other oil paths, and the oil path containing the available section is screened out from all oil paths as a parallel oil path;

[0085] The communication of the second branch in each parallel oil path is controlled so that the oil processing mode of the oil path through which each parallel oil path flows is exactly the same as the oil processing mode of the current oil path, and the lubricating oil is synchronously transmitted by using the current oil path and the parallel oil path.

[0086] In implementation, the above is:

[0087] Oil path A: oil pump P1→heating unit H1-1→heating unit H1-2→outlet.

[0088] Oil path B: oil pump P1→heating unit H2-1→heating unit H2-2→impurity removal unit F1→outlet.

[0089] Oil path C: oil pump P1→heating unit H3-1→heating unit H3-2→impurity removal unit F2→water removal unit W→outlet.

[0090] Referring to Figure 5 , the application proposes that: between the above three oil paths, a first branch is established, and a first branch valve (such as a three-way electromagnetic valve) is installed on the first branch, one end of the first branch is communicated with the inlet / outlet pipeline of any processing unit in one of the oil paths, the other end of the first branch is communicated with the inlet / outlet pipeline of any processing unit in another oil path, and correspondingly, the application refers to the communication position of the oil path and the first branch as a communication node, so as to control the generation of the communication node at different positions of the above three oil paths by controlling the opening and closing of the first branch valve at different positions, thereby realizing the communication across the oil paths by using the communication node.

[0091] The first branch and the first branch valve are arranged to realize the connection of the cross-oil path, so that when a fault unit (i.e. a processing unit that is out of order, and the fault here covers the case that the impurity removal unit needs to be shut down for filter replacement, i.e. all processing units that need to be shut down for maintenance) exists in the current oil path corresponding to the current oil treatment mode, the other oil paths containing processing units with the same function as the fault unit are used to undertake the lubricating oil in the current oil path, and the processing operation corresponding to the fault unit is performed. For example, if the current oil treatment mode is the heating, impurity removal and water removal mode, the corresponding current oil path is oil path C, and if the fault unit is the impurity removal unit F2, the available sections of the current oil path are "oil pump P1→heating unit H3-1→heating unit H3-2" and "water removal unit W→outlet", and the isolated section is "impurity removal unit F2".

[0092] Then, from the other remaining oil paths except the current oil path, it is determined whether there is an oil path containing processing units with the same function as all the fault units contained in the isolated section, and if so, the corresponding oil path is the available oil path (for example, in the above example, the available oil path of the current oil path C is oil path B); correspondingly, the section in the available oil path where the processing units with the same function as all the fault units contained in the isolated section are located is the target section (for example, in the above example, "impurity removal unit F1" in the available oil path B), and all the first branches between the available oil path and the current oil path that are connected to the target section are found (in combination with the above example, the corresponding first branches are the two first branches shown by arrows X and Y in FIG. 1B), and the first branch valve on the corresponding first branch is opened to realize the connection between the available section of the available oil path and the target section, i.e. the finally obtained obstacle avoidance oil path is: oil pump P1→heating unit H3-1→heating unit H3-2→impurity removal unit F1→water removal unit W→outlet. Figure 5

[0093] In addition, a second branch is arranged on each oil path, and there is a processing unit in parallel with the second branch in the oil path to which the second branch belongs, such as the second branch R1 in parallel with the impurity removal unit F1 as shown in FIG. 1C. Figure 5 The inlet end and the outlet end of the second branch R1 correspond to the inlet end and the outlet end of the impurity removal unit F1 respectively, and the inlet end of the second branch is provided with a second branch valve (such as a three-way valve) for controlling the flow of the lubricating oil into the second branch R1 or the impurity removal unit F1. If the second branch valve is switched to be connected to the second branch R1, the flow path of the lubricating oil in the oil path B is as follows:

[0094] ​the oil treatment mode corresponding to the current oil circuit, all the processing units contained in the current oil circuit are contained in the parallel oil circuit, and the parallel oil circuit refers to an oil circuit that contains all the processing units in the current oil circuit among the other oil circuits except the current oil circuit. If the parallel oil circuit can be selected from all the oil circuits, it is considered that the current oil treatment mode meets the multi-path parallel processing condition. In combination with the example in the foregoing, if the current oil treatment mode is the single heating mode, the corresponding current oil circuit is oil circuit A, and since the remaining oil circuits (i.e., oil circuit B and oil circuit C) all contain all the processing units (i.e., two heating units) corresponding to oil circuit A, it is considered that the single heating mode corresponding to the current oil circuit A meets the multi-path parallel processing condition, and the corresponding parallel oil circuits are oil circuit B and oil circuit C. There is an implicit condition here, that is, all the processing units shared by the parallel oil circuit and the current oil circuit are in a normal operating state (i.e., a non-fault state). The parallel path refers to the path in which the processing units shared by the current oil circuit and the parallel oil circuit are located, that is, in the current oil circuit: "oil pump P1→heating unit H1-1→heating unit H1-2", in the parallel oil circuit B: "oil pump P1→heating unit H2-1→heating unit H2-2", and in the parallel oil circuit C: "oil pump P1→heating unit H3-1→heating unit H3-2". After the parallel oil circuit and the parallel path are found, all the processing units (hereinafter referred to as deactivated units, such as the deactivated unit in the parallel oil circuit B: the impurity removal unit F1, and the deactivated unit in the parallel oil circuit C: the water removal unit W) in the remaining path segments of the parallel oil circuit except the parallel path segment are determined, and the second branch corresponding to the deactivated units is connected to the parallel path segment, that is, the second branch valve on the corresponding second branch is switched, so that the lubricating oil flows only to the second branch when flowing into the remaining path segment, bypassing the deactivated units. The final lubricating oil flow path of the parallel oil circuit B is changed to: "oil pump P1→heating unit H2-1→heating unit H2-2→outlet", and the final lubricating oil flow path of the parallel oil circuit C is changed to: "oil pump P1→heating unit H3-1→heating unit H3-2→outlet".

[0095] In other embodiments, when a fault unit occurs, the first branch and the second branch can also be used in combination to find an obstacle-avoiding oil circuit. For example, when the current oil circuit is oil circuit B, and the corresponding fault unit is the impurity removal unit F1, the corresponding available oil circuit is oil circuit C containing the impurity removal unit F2. The obstacle-avoiding oil circuit can be found by using the first branch and the second branch in combination. Figure 5The first branch shown by arrow X and arrow Y forms an obstacle avoidance oil path: oil pump P1→heating unit H2-1→heating unit H2-2→impurity removal unit F2→outlet; of course, the obstacle avoidance oil path can also be obtained by using the first branch shown by arrow X and the second branch shown by arrow Z (i.e., bypassing the water removal unit W).

[0096] Optionally, the intelligent oil treatment method further comprises the following steps:

[0097] Real-time record the cumulative working time length of each impurity removal unit, the cumulative treatment oil volume in the cumulative working time length, and the pipeline pressure difference change rate of the inlet and outlet of the impurity removal unit;

[0098] According to the pipeline pressure difference change rate, the maintenance time of the impurity removal unit is predicted in real time for the staff to know;

[0099] When the time difference between the current time and the maintenance time is less than the preset warning time difference, the corresponding impurity removal unit is determined as a fault unit.

[0100] In implementation, a flow sensor is installed in advance in the inlet pipeline of each impurity removal unit for monitoring the real-time flow of lubricating oil. The processing system is used to start timing when the impurity removal unit is started and the flow sensor detects flow data, and stop timing when the flow sensor has no data (i.e., only record the time length when the lubricating oil flows through the impurity removal unit), so as to form a single working time length, and then the cumulative working time length is obtained by real-time accumulation according to the single working time length. The cumulative treatment oil volume Q is the accumulation of flow at each time in the cumulative working time length.

[0101] The processing system is used to, based on the cumulative treatment oil volume Q at different times in the cumulative working time length and the oil path pressure difference data ΔP obtained by the foregoing calculation at the corresponding time, real-time fit the change curve of the oil path pressure difference data ΔP changing with the cumulative treatment oil volume Q by using the least square method according to N data points (i.e., each data point includes the cumulative treatment oil volume Q and the oil path pressure difference data ΔP at the corresponding recording time) recorded before the current time, the slope of the curve is the pipeline pressure difference change rate m, and a fitting equation: ΔP=m×Q+c is obtained, where c can be understood as the oil path pressure difference data under the initial clean state of the filter element of the impurity removal unit; then a preset oil path pressure difference threshold ΔPmax is substituted into the foregoing fitting equation, the calculated Q value is taken as Qmax, and the residual treatment oil volume is obtained by subtracting the cumulative treatment oil volume at the current time from Qmax.

[0102] Similarly, the processing system also uses the data points recorded in real time (including the cumulative working time and the cumulative processing oil volume) to periodically use linear regression to fit a curve of the cumulative processing oil volume changing with the cumulative working time according to multiple data points recorded before the current time, and the corresponding fitting equation is Q=qxt+b, where q is the average flow (L / h), t is the cumulative running time (h), Q is the cumulative processing oil volume (L), and b is the intercept (referring to the start time of recording, generally 0), then the remaining processing oil volume calculated at the current time is substituted into the fitting equation as Q to obtain t (i.e. the remaining processing time), and the maintenance time T=t0+t can be calculated according to the remaining processing time t and the current time point t0, when the time difference between the current time and the maintenance time is less than the preset warning time difference, the corresponding impurity removal unit is determined as the fault unit, so as to form the obstacle avoidance oil path in combination with the foregoing scheme.

[0103] Optionally, the intelligent oil processing method further comprises the following steps:

[0105] In implementation, the processing system reads the temperature data of the temperature sensor preset at the inlet of the oil path (as the initial temperature of the lubricating oil, T_in), calculates F_ff as the pumping speed according to the preset ideal temperature (T_target), the preset effective power of the current heating unit (P_heat), and the preset formula F_ff=P_heat / [c*ρ*(T_target-T_in)]. Wherein, c is the specific heat capacity of the transmitted lubricating oil, and p is the density of the transmitted lubricating oil.
