Description

[0001] The invention relates to electrical engineering, specifically to a pulsed electrohydraulic system for producing individual carbon elements and various carbon molecular structures during the degradation of various types of hydrocarbon liquids. The claimed invention is used to produce a lubricating composition based on carbon nanoparticles.

[0002] There are various methods for producing lubricants based on carbon nanoparticles, as well as various industrial applications of the electrohydraulic effect. This invention aims to develop a technical solution for utilizing the electrohydraulic effect to create a lubricating composition with carbon nanoparticles using an effective device. The device's operation results in an electrohydraulic discharge in an oil medium, resulting in the formation of carbon nanoparticles and carbon structures. This lubricating composition is designed to reduce the coefficient of friction and increase the thermal and kinematic wear resistance of friction pair working surfaces. Since its discovery, the electrohydraulic effect has been and remains a constant source of inspiration for numerous progressive technological processes, which are now widely used worldwide in various industries.It is also effective to create a lubricant composition based on industrial and / or hydrocracked base oil, and / or saturated and / or unsaturated hydrocarbons, and / or alicyclic and / or aromatic hydrocarbons. The operation of a pulsed electrohydraulic unit is based on the electrohydraulic effect (Yutkin effect). This effect consists of the fact that a pulsed electrical discharge in the liquid around the zone of its formation generates extremely high hydraulic pressures capable of performing useful mechanical work. However, devices for achieving this electrohydraulic effect can vary. One of the key elements of such a unit is a spark gap for generating a pulsed discharge. Maintaining the required gap size between the electrodes is an important aspect of operation.

[0003] The patent GB 1113750 from 15.05.1968 for the invention "Electrohydraulic installation" describes a spark gap for a pulse installation of the electrohydraulic type, comprising: a housing; a fixed electrode (cathode), removable located on the housing and connected to a current-conducting element; a movable electrode (anode), located on a drive rod installed in the housing with the possibility of axial movement, wherein the movable electrode is located in an insulating tube and is isolated from the housing using insulators; an actuator in the form of a reducer, connected to the rod, with the possibility of moving the rod with the anode. In this analogue, the authors emphasize that the movement of the anode relative to the cathode is carried out solely for the purpose of maintaining a predetermined constant gap value during operation of the spark gap.

[0004] The closest analogue (prototype) in terms of the set of existing features is the invention according to the Russian Federation patent No. 2483101 dated 01 / 29 / 2010 entitled "Method for producing a lubricating composition" (IPC C10M 177 / 00; C10M 159 / 12; C10G 15 / 08; B82Y 30 / 00). The specified pulse electrohydraulic unit includes two electrodes made of a non-magnetic conductive material of finite resistance with a gap between them, located in hydrocarbon oil, connected to a source (generator) of high-voltage pulses in such a way that the discharge current lies in the range from a half-period to several periods, and the electrodes have the shape of a truncated sphere.

[0005] The disadvantages of this invention include the lack of disclosure of the physical parameters of the system, which prevents the system's operation from being reproduced and the production of a lubricating composition containing nanocarbon components. The parameters of the electrodes, which are an important component of the electrohydraulic system, are unknown. The gap between the electrodes, which is a crucial parameter for pulse generation, is also unknown. The high-voltage parameter is also unknown. Since a spark gap for generating a pulsed discharge is an essential component of the pulsed electrohydraulic system, the proposed embodiment describes a system with a spark gap.

[0006] The disadvantages of existing arrester inventions include instability of discharge parameters, low efficiency; the need to stop the electrohydraulic system to establish the gap between the electrodes; the occurrence of parasitic currents and increased electrode wear; stress on the actuator due to impact forces during operation; and insufficient positioning accuracy of the movable electrode in the operating and recharging positions. These disadvantages define the technical problem that the claimed invention aims to solve.

[0007] The goal of the developer of the new pulsed electrohydraulic unit was to create an improved design while eliminating the shortcomings of known analogs. The technical result of the invention is to increase the efficiency and cost-effectiveness of the process of breaking down hydrocarbon molecules to form carbon nanoparticles, as well as to improve the stability and controllability of the arc discharge in the liquid and the working gap. This technical result is achieved through a combination of essential features.

[0008] The essence of the invention is that the pulse electrohydraulic installation contains a transformer (1) connected to a first voltage multiplier consisting of series-parallel connected capacitors (3) and series-connected diodes (2) and a voltage control device (22) with a current-limiting resistance (23) in the reverse circuit of arresters, which are connected through a switch (27) to a second voltage multiplier consisting of series-parallel connected capacitors (28), series-connected resistors (26) and diodes (4), to which at least two arresters (5) are connected, immersed in a reactor (29), wherein the arrester (5) includes a housing (6), a fixed electrode (13) fixed to the housing (6), a movable electrode (12) fixed to a drive rod (10),wherein the drive rod (10) is installed with the possibility of moving the movable electrode (13) relative to the fixed electrode (12) between the working position and the position of recharging the capacitors (3), and also the adjustment unit (15) is connected to the drive rod (10). Wherein the spark gap (5) is made with a pneumatic drive (16) connected to the drive rod (10) and to the adjustment unit (15) with a drive of the adjustment unit (20), made with the possibility of automatically adjusting the working gap between the electrodes (12) and (13) and with the possibility of rotation by a certain angle, providing translational movement of the drive rod (10). At the same time, the drive rod (10) is placed in the insulating tube (17) and is insulated from the housing (6) by means of insulators (11). And the pneumatic drive (16) is connected to the drive rod (10) through the insulator (11). In addition, a single-phase transformer (1) with a capacity of 10 kVA, a HV winding voltage of 6 kV, and a LV winding voltage of 230 V is used.the power supply frequency is 50 Hz. And the operating method of the pulse electrohydraulic unit according to paragraph 1 includes introducing oil or oil and distilled water into the reactor (30), thoroughly mixing until a homogeneous state is obtained, and carrying out the electrohydraulic process.

[0042] The main processes occur in reactor 29, a device where the process of separating carbon compounds in an oil medium occurs. A key component of the setup is spark gap 5, a device for producing a high-voltage discharge in an oil medium. The setup itself is a combination of devices and equipment that participate in the production of oil-carbon-containing materials. The basic operating principle of the electrohydraulic setup is the stepwise increase of the input voltage to the required value, which is required to generate a high-voltage arc in spark gap 5 of reactor 29. The input voltage is initially linearly increased on input step-up transformer 1. The resulting voltage is then fed from the first voltage multiplier through diodes 4 to switching device 27 for subsequent step-up and discharge. Switching device 27 performs switching functions for charging and discharging the second voltage multiplier.It consists of at least one pair of contacts, which serve for charging and discharging. With the help of the switching device 27, the last capacitor group 28 (series-installed capacitors) is initially charged. The voltage increase is performed and controlled by time. While the switching device 27 is in the charging position, the last capacitor group 28 gains charge. The voltage control device 22 is used to control the voltage at the output of the second multiplier. In the developed pulse electrohydraulic unit, an oil transformer OMP-10 / 10-UKHL1 or its analogues, for example, the dry type OL-10 / 10 (6) UKHL1, is taken as transformer 1. Characteristics of transformer 1: power - 10 kVA, voltage of the HV winding - 6 kV, LV winding - 230 V, power supply network frequency - 50 Hz, single-phase. An asymmetrical voltage doubler circuit is selected for the voltage multiplier. The voltage multiplier circuit consists of two multipliers.The first voltage multiplier consists of capacitors 3 and diodes 2. The second voltage multiplier consists of a group of capacitors 28, resistors 26 for eliminating voltage imbalance on the capacitors and for discharging the capacitors, and diodes 4. By means of switches 27, diodes 4 are alternately engaged in the second voltage multiplier. The first multiplier consists of capacitors 3 connected in series-parallel and diodes 2 connected in series. Transformer 1, the first multiplier, consisting of elements 2 and 3, and diode 4 are part of the circuit common to two channels 24 and 25. The nominal voltage of capacitors 3 used in the circuit is 10 kV, the capacitance is 1 μF. The voltage on the first voltage multiplier will be 8.5 kV. To operate at this voltage, two capacitors 3 are connected in series. With this connection, they can withstand voltages of up to 20 kV. In this case, the capacitance of capacitors 3 when connected in series became 0.5 μF.To increase the capacitance to 1 μF, two chains of capacitors 3, indicated above, are connected in parallel. The constant reverse voltage of diodes 2, 4 is 10 kV. Series connection of two diodes 2, 4 allows their use at voltages up to 20 kV. The voltage on the second multiplier will be 17 kV. Channel 24 is represented by a series-parallel connection of capacitors 28 with resistors 26, diodes 4 and switch 27 connected in parallel to them. Channel 25 is represented by a series-parallel connection of capacitors 28 with resistors 26, diodes 4 and switch 27 connected in parallel to them. Diodes 4 in channels 24, 25 are used alternately when switches 27 of each channel are operating. In channels 24 and 25, the voltage on voltage multiplier 28 will be 17 kV. Capacitors 28 are rated for 5 kV. Their capacitance is 40 μF. Connecting four capacitors 28 in series allows them to be connected to voltages up to 20 kV.The capacitance of the circuit of four series-connected capacitors 28 decreases by a factor of four. To increase the capacitance of channels 24 and 25, the two previously mentioned circuits of four capacitors 28 are connected in parallel. The capacitance of capacitors 28 of each of channels 24 and 25 is equal to 20 μF. Switches 27 alternately connect channels 24 and 25 to the first voltage multiplier. Capacitors 28 of channel 24 and capacitors 28 of channel 25 are alternately charged to a voltage value of double the peak value. They are discharged in the same order on their spark gaps 5. In the return circuit of spark gaps 5, there is a current-limiting resistor 23. The resistance limits the discharge current of capacitors 28. A pneumatic or electromechanical drive is used to switch switches 27 and spark gaps 5. Control signals to the drives are received from the microcontroller. Depending on the intended operating mode of the device, changes must be made to the circuit diagram.For the hard operating mode of 10-40 kV, transformers 1 for 10 / 0.23 kV and 6 / 0.23 kV with a multiplier with a coefficient of 1 or higher can be used as a high-voltage source. For the medium operating mode with a voltage of 5-10 kV, transformer 1 for 6 / 0.23 kV with a multiplier with a coefficient of 1 or higher is used as a voltage source. Or, custom-made transformers 1 for voltages from 2 kV to 3 kV and included in a circuit with a voltage multiplier with a coefficient of 2 or higher can be used. For the soft operating mode from 2 to 4 kV, custom-made transformers with a voltage multiplier with a coefficient of 1 can be used as a high-voltage source. The characteristics of capacitors 3 and 28, their number, and the connection diagrams in the circuits of the first and second multipliers are selected depending on the operating mode of the device. Voltage is supplied from the second voltage multiplier to arrester 5.At this voltage, a breakdown of the oil located between electrodes 12 and 13 of the spark gap 5 occurs. Carbon nanoparticles and fullerenes are formed in the oil in the arc plasma of spark gap 5. The basic operating principles of spark gap 5: during charging, spark gap 5 inside reactor 29 is in the upper position. After the charging time has elapsed, switch 27 switches and disconnects the charging circuit from the last capacitor group 29 in turn. At the moment of switching, a pulse is sent to the actuator of spark gap 5, which allows the mechanism of spark gap 5 to begin approaching the discharge point in the oil medium. When switch 27 has completely disconnected the charging circuit of the last capacitor group 29, the second contact pair of switch 27 closes the discharge circuit. The discharge circuit is connected to spark gap 5. When the second contact pair of switch 27 closes, the mechanism of spark gap 5 is already near the discharge point.At the moment of closing the second contact pair of switch 27, an arc is formed and the last capacitor group 29 is discharged. After the discharge (controlled by time), a pulse is again sent to the actuator of spark gap 5, which causes its mechanism to move away (rise upward) from the discharge point in reactor 29. During the upward movement of the mechanism of spark gap 5 (from the discharge point), switch 27 disconnects the second contact pair and re-connects the first one to re-charge the last capacitor group 29. Spark gap 5 includes a housing 6, a drive rod 10, a movable electrode 12, a fixed electrode 13, an adjustment unit 15 and a pneumatic drive 16. Housing 6 is open and fixed and is the basis for fastening the structural elements. Housing 6 may include at least two horizontal posts 7 connected to each other by at least two vertical posts 8, as well as an upper plate 9.In the lower part of the housing 6, a fixed electrode 12 is fixed on a removable plate 18. The fixed electrode 13 is connected to the power supply through a conductive copper rod 14, fixed to the side of the housing 6. A positive or negative charge is applied to the conductive copper rod 14, depending on the forward or reverse connection of the electrical circuit. The drive rod 10 is placed in the middle part of the housing 8 in the insulating tube 17, and its ends are insulated from the housing 6 and the pneumatic drive 16 by means of insulators 11. At the lower end of the drive rod 10, a movable electrode 12 is fixed, to which voltage is supplied through a flexible conductive bus 19; to the upper end, through an insulator 11, a pneumatic drive 16 is attached, which carries out a controlled reciprocating movement of the drive rod 10 between the working (lower) position of the electrode 12 and the position of recharging the capacitors (upper).In the upper part of the drive rod 10, a thread is formed and an adjustment unit 15 is installed, which is in constant engagement with the drive 20. The drive 20 is responsible for the movement of the adjustment unit 15, which, when rotating, interacts with the thread of the rod 8 and rests against the insulator 11, located on the horizontal post 7 of the housing 6. The adjustment unit 15 moves the rod 10 in the axial direction, performing automatic adjustment of the gap between the electrodes 12 and 13 in any position. The adjustment unit 15 is configured to automatically adjust the working gap between the electrodes 12 and 13 with the ability to rotate it by a certain angle, which ensures the translational movement of the drive rod in the axial direction. The adjustment unit 15, the drive of the adjustment unit 20 are configured to be connected to a programmable logic controller or other automation device.In this specific example, a Siemens programmable logic controller is used. Its operation is configured by the operator based on duty cycles, recharge cycles, and the breakdown parameters of the arrester. The programmable controller transmits a motion signal to actuator 20 of adjustment unit 15, which, when received, rotates the arrester to a predetermined angle. Electrodes 12 and 13 can be made of various metals or alloys to produce various metal-carbon compounds and hydrocarbon destruction. The movable arrester is used as part of a pulsed hydraulic system in vessels that act as a reactor filled with hydrocarbon liquid, where destruction and synthesis occur via an electric discharge.The operating cycle of the apparatus includes the movement of the movable electrode 12 between two positions: the capacitor recharging position, in which the movable electrode 12 is moved away from the fixed electrode 13 and no discharge occurs in the liquid, and the operating position, in which an electrical breakdown occurs between the electrodes 12 and 13 and a shock wave is formed in the liquid. In the initial recharging position, when the movable electrode 12 is located at a distance of 15-20 mm from the fixed electrode 13 in the upper position, the capacitors of the apparatus are charged. To move to the operating (lower) position, the pneumatic drive 16 moves the rod 10 downwards until the stop of the adjustment unit 15 in the operating position, ensuring an operating gap between the electrodes 12 and 13 of approximately 2 mm. In the operating position, a high-voltage pulse is supplied through the discharge circuit to the electrodes 12 and 13, between them an electrical breakdown of the liquid and its evaporation occurs, creating a sharp expansion of the gaseous discharge products.After discharge generation is complete, pneumatic drive 16 moves to the upper position (recharge position), and movable electrode 12 is retracted. The cycles are then repeated. During use, the electrodes inevitably wear out, as does the mechanical displacement of the spark gap's moving elements as a result of impact loading, requiring adjustment of the gap between electrodes 12 and 13. This adjustment is accomplished using adjusting unit 15, providing translational movement of rod 10. The accuracy of the gap between electrodes 12 and 13 is ensured by the rotation angle of adjusting unit 15 and drive 20, and is set programmatically based on the performance characteristics of electrodes 12 and 13, depending on the number of operating and recharge cycles. Spark gap 5 is immersed in an oil-filled container (reactor) in its operating position.Additionally, the tank (reactor) may contain a mixing system in the form of a paddle stirrer or a magnetic stirrer with adjustable speed, rotating at 500-1000 rpm. The mixing system maintains the homogeneity of the mixture during processing. The filtration system removes sediment and large particles from the finished mixture. Transformer 1 can be connected to the control panel for automated control of the following parameters: voltage, frequency, processing time. The following additional sensors can be installed in the pulse electrohydraulic unit: 1. Optical sensors (laser diffraction or spectrophotometry). They measure the intensity of light scattering or optical density to assess particle size and concentration. Location: mounted on the tank wall or in the circulation loop. Advantages: high accuracy, continuous monitoring capability. 2. Conductometric sensors.Measure the electrical conductivity of the mixture to assess the ion content (e.g., from water or metal additives). Location: at the bottom of the tank, where additives may accumulate. 3. Infrared (IR) sensors. Analyze the spectral characteristics of the hydrocarbon mixture to determine the composition and content of nanoparticles. Application: Monitor the degree of degradation of hydrocarbon molecules. 4. Acid number sensors. Determine the acidity of the mixture to monitor possible oil and water degradation.

[0043] The pulse electrohydraulic unit operates as follows. A base oil, or a base oil and distilled water, are introduced into a vessel (reactor). It is also effective for creating a lubricating composition based on industrial and / or hydrocracking base oil, and / or saturated and / or unsaturated hydrocarbons, and / or alicyclic and / or aromatic hydrocarbons. The mixture is thoroughly mixed until homogeneous. The electrohydraulic process then takes place. The unit generates high-voltage pulses, ensuring the destruction of hydrocarbon molecules in the base oil and the formation of carbon nanoparticles. At the same time, nanoparticles and stearates (if used) are uniformly distributed throughout the mixture. During the entire process, gaseous products released during the formation of a current arc in the oil medium are pumped out of the reactor. The unit's operating principle, described above, is cyclical.The cycle starts and stops when the oil mixture reaches optimal saturation with carbon compounds. Throughout the process, gaseous products released during the formation of a current arc in the oil medium are pumped out of the reactor. Cycle initiation, charging time, and switching time are controlled automatically by an automated control system based on a modern logic controller. The design of arrester 5 utilizes an adjustment unit 15 with a pneumatic drive 16, which are in constant engagement with each other and with a drive rod 10. The pneumatic drive 16 also serves as an actuator, with the option of installing feedback sensors 21, which are capable of determining the position of the piston of the pneumatic drive 16 cylinder. Position sensor 21 provides control and feedback, increasing operational reliability and safety.Furthermore, its universal compatibility with automation systems makes it convenient and flexible to use when adjusting the pneumatic drive's operation. Sensors 21 can be installed in grooves on the cylinder body or on liners and studs. Pneumatic drive 16 ensures the return of movable electrode 12 from the operating position to the capacitor recharging position, which also optimizes the design of discharge 5, making it more reliable and accurate. The use of a "movable" circuit of electrodes 12 and 13 with a complete break in the electrical circuit allows for the full charging of voltage multiplier 2 for the next discharge cycle, eliminates current leakage, and reduces wear on electrodes 12 and 13, resulting in stable and controllable discharge parameters.Moreover, the use of automatic adjustment of the working gap between electrodes 12 and 13 allows for precise setting and control of the gap size between electrodes 12 and 13 in any position during operation, even when periodic surface wear and element displacement occur, without stopping the process or the electrohydraulic unit itself, thereby reducing downtime. This solution allows for the reciprocating motion to be superimposed on the actuator (pneumatic cylinder), simplifying the arrester design and making it more reliable and precise, as the size and stiffness of the spring are not specified in the closest patent. Furthermore, over time, the spring may also lose its properties, which could affect the precision of the upper electrode 12.Moreover, the pneumatic cylinder's design features enable smoother and more precise reciprocating movements, which also eliminates the need for a damper, the characteristics of which are also undefined. Thus, all features of the invention are aimed at achieving a unified technical result: increasing the stability and controllability of the arc discharge in liquid, enhancing process automation, and reducing human intervention. This results in increased reliability, reduced wear, and a longer service life for the arrester. The efficiency of the electrohydraulic system is also improved, the level of automation and continuity of operation of the electrohydraulic system is increased, and human intervention is reduced. Filtration is then performed, if necessary. After processing, the mixture is filtered through a filter with a pore size of 1-20 μm to remove large particles.Dispersion uniformity is also assessed using laser diffraction or dynamic light scattering. The tribological properties of the resulting lubricant composition are also tested using a friction machine (SMT-1) to determine the coefficient of friction, wear resistance, and scuff resistance.
