[0040] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0041] Figure 1 and Figure 2 FIG. 2 shows a schematic diagram of the structure of the high pressure filter station test system according to an embodiment of the present application. Figure 1 and Figure 2 As shown, an embodiment of the present application provides a high-pressure filter station testing system, comprising:

[0042] The liquid supply module comprises a liquid tank 11 and a liquid supply pump 12, wherein the inlet of the liquid supply pump 12 is connected to the liquid tank 11;

[0043] The test bench includes a reversing valve 21, the outlet of the liquid supply pump 12 is connected to the liquid inlet 211 of the reversing valve 21, the reversing valve 21 has multiple functional ports, the multiple functional ports include multiple test functional ports and a pressure relief functional port 212, the multiple test functional ports are respectively connected to the liquid inlet (P port) of the high-pressure filter station 20 to be tested through corresponding pipelines to form different test hydraulic circuits, the pressure relief functional port 212 is connected to the liquid tank 11 to form a pressure relief circuit 201, and the liquid return port 214 of the reversing valve 21 and the liquid return port of the high-pressure filter station 20 to be tested are respectively connected to the liquid tank 11;

[0044] The control module 3 is connected to the reversing valve 21 and is used for switching the plurality of test hydraulic circuits and the pressure relief circuit.

[0045] Among them, the liquid supply module is used to provide hydraulic power for the entire test system. The test oil in the liquid tank 11 can be pumped to the liquid inlet 211 of the reversing valve 21 by the liquid supply pump 12, and the liquid pipeline between the liquid inlet 211 of the reversing valve 21 and the liquid supply pump 12 can be the liquid inlet pipeline of the test bench. The liquid supply pump 12 is preferably a plunger pump. Different test function ports of the reversing valve are connected to the liquid inlet of the high-pressure filter station 20 to be tested through corresponding liquid pipelines, and different test loops can be formed to test the performance of the high-pressure filter station 20 product under various test conditions. The liquid pipeline between the test function port of the reversing valve 21 and the liquid inlet of the high-pressure filter station 20 can be the liquid outlet pipeline of the test bench. At the same time, in this embodiment, a pressure relief function port 212 is set on the reversing valve 21, and the pressure relief function port 212 is connected to the liquid tank 11 to form a pressure relief loop 201, which can be used to quickly relieve pressure after the test to ensure the safety of the test.

[0046] When the high-pressure filter station 20 under test is tested using different test function ports, the liquid return port of the high-pressure filter station 20 under test is normally closed, and manual operation is required to open the liquid return port to relieve the pressure of the high-pressure filter station 20 under test through the first liquid return pipeline 301 between the liquid return port of the high-pressure filter station 20 under test and the liquid tank 11; similarly, the liquid return port 214 of the reversing valve 21 is connected to the liquid tank 11, and the liquid return port 214 of the reversing valve 21 is normally closed. After the entire test system is tested, the liquid return port 214 can be opened for pressure relief as needed to protect the safety of the system.

[0047] The reversing valve 21 is preferably an electro-hydraulic controlled reversing valve, which can realize the opening and disconnection of different functional ports of the electro-hydraulic controlled reversing valve by controlling the on and off states of the electromagnet of the electromagnetic pilot valve, automatically switch different test hydraulic circuits for testing, and automatically release pressure after the test results are qualified.

[0048] like Figure 2As shown, the control module 3 includes an industrial computer (such as an industrial host) and corresponding measurement and control software, etc., to realize the automatic control of the test. In this embodiment, the control module 3 includes a PLC programmable control system, an operation panel, a human-machine interface, etc. The operation panel is provided with corresponding control buttons, and the user can perform test control by operating the control buttons. The user can also input test parameters through the human-machine interface, and the human-machine interface can also display the corresponding working status. In this embodiment, the control module 3 can control the test system on-site, for example, the operation interface and the human-machine interaction interface are set on the PLC host cabinet arranged on-site, and remote control can also be performed, for example, the PLC host arranged on-site is remotely controlled by a remote industrial computer.

[0049] The high-pressure filter station test system provided in the embodiment of the present application connects the liquid supply module with the liquid inlet pipeline of the test bench. The test bench includes a reversing valve 21 with multiple functional ports. The test functional ports among the multiple functional ports are connected to the liquid inlet of the tested high-pressure filter station 20 through corresponding liquid pipelines to form different test circuits. The product performance of the high-pressure filter station 20 can be tested under different test conditions without configuring different test hydraulic circuits one by one, which can improve the test efficiency of the high-pressure filter station 20; at the same time, the pressure relief functional port 212 among the multiple functional ports is connected to the liquid tank 11 to form a pressure relief circuit 201, which can improve the test safety; in this embodiment, the on and off of different hydraulic circuits can be controlled by controlling the reversing valve 21, and the control is precise and convenient, which can improve the accuracy of the test results and further improve the test efficiency; the test system has the advantages of high integration, comprehensive performance, high test efficiency, high test accuracy, and high safety.

[0050] Understandably, Figure 1 In order to distinguish the liquid supply and liquid return of the liquid tank 11, the liquid tank 11 is drawn as two parts. Figure 1 The two liquid tanks 11 in are the same liquid tank.

[0051] In some embodiments, Figure 1 As shown, the test function port includes a first test function port 2131, a second test function port 2132 and a third test function port 2133. The first test function port 2131 cooperates with the high-pressure filter station 20 under test to form a sealed loop 202, the second test function port 2132 cooperates with the high-pressure filter station 20 under test to form a low-pressure loop 203, and the third test function port 2133 cooperates with the high-pressure filter station under test to form a high-pressure loop 204.

[0052] In this embodiment, the sealing, low pressure and high pressure performances of the high pressure filter station 20 can be tested respectively through the first test function port 2131 , the second test function port 2132 and the third test function port 2133 .

[0053] It should be noted that the pressure relief circuit 201 can be used for pressure relief protection after testing with each test hydraulic circuit, and can also be used for pressure relief protection after testing with multiple test hydraulic circuits. For example, when performing sealing and low-pressure performance tests, the pressures required for the two are close, and after the sealing and low-pressure performance tests are completed, the pressure can be switched to the pressure relief function port 212 for pressure relief; if a high-pressure performance test is performed, after the test is completed, it is promptly switched to the pressure relief function port 212 for pressure relief protection, and then switched to other test function ports for testing. The return liquid port 214 of the reversing valve 21 is mainly used for pressure relief protection after all test items are completed. Through the cooperation of the pressure relief function port 212 and the return liquid port 214, the system can be protected in a timely and reliable manner to ensure the safety of the test. Further, if Figure 1 As shown, each of the test hydraulic circuits is provided with a group of one-way valves and overflow valves, each of the one-way valves is arranged on the pipeline between the corresponding test function port and the liquid inlet of the tested high-pressure filter station 20, the inlet of each overflow valve is connected to the corresponding test function port, and the outlet of each overflow valve is connected to the liquid tank 11.

[0054] The one-way valve is used to control the test hydraulic circuit between each test function port and the liquid inlet of the high-pressure filter station 20 to avoid liquid backflow. The overflow valve opens or closes according to the pressure of the corresponding test hydraulic circuit to ensure the reliable operation of the test hydraulic circuit. During normal testing, the one-way valve is opened, and the liquid flowing out of the test function port flows to the liquid inlet of the tested high-pressure filter station 20 through the test hydraulic circuit. When the pressure in the test hydraulic circuit reaches the opening pressure of the overflow valve, that is, when the test system is overloaded, the overflow valve opens. When the test hydraulic circuit is overloaded, the excess liquid returns to the liquid tank 11 through the overflow valve to unload the pressure of the overloaded part, so that the test hydraulic circuit works at a suitable pressure, avoids excessive pressure in the test hydraulic circuit, protects the test system, and extends the service life of the test system.

[0055] In this embodiment, the sealing circuit 202 is provided with a first one-way valve 221 and a first overflow valve 231 , the low-pressure circuit 203 is provided with a second one-way valve 222 and a second overflow valve 232 , and the high-pressure circuit 204 is provided with a third one-way valve 223 and a third overflow valve 233 .

[0056] In some embodiments, the test bench further includes a first spherical reversing valve 24 and a liquid return circuit breaker valve 25 disposed between the outlet of the overflow valve and the liquid tank 11 , and the first spherical reversing valve 24 is disposed upstream of the liquid return circuit breaker valve 25 .

[0057] The first spherical reversing valve 24 is mainly used when repairing or replacing the hydraulic pipeline. During repair, the first spherical reversing valve 24 is closed, and the liquid circuit can be closed to prevent liquid from spilling.

[0058] The liquid return cut-off valve 25 is similar to a one-way valve, so that the liquid can only enter the liquid tank 11 from the liquid return port 214 of the reversing valve 21 or the liquid return port of the tested high-pressure filter station 20, thereby preventing the liquid from flowing back in the liquid tank 11.

[0059] In some embodiments, a pressure stabilizer 26 is provided on the test hydraulic circuit to stabilize the pressure of the test hydraulic circuit and adjust the pressure fluctuation of the test system. In this embodiment, the pressure stabilizer 26 is provided downstream of the one-way valve and the overflow valve on the test hydraulic circuit, that is, it can be provided on the common pipeline of multiple test hydraulic circuits, so that one pressure stabilizer 26 is conveniently used for pressure stabilization, which can reduce the number of test components.

[0060] In some embodiments, Figure 1 As shown, the pressure relief circuit 201 is provided with a hydraulically controlled one-way valve 27 , and the hydraulically controlled one-way valve 27 is arranged upstream of the connection between the pressure relief circuit 201 and the first liquid return pipeline 301 .

[0061] In this embodiment, when the test function port is used for testing, the liquid return port of the tested high-pressure filter station 20 is closed, and the hydraulically controlled one-way valve 27 is closed, so that a closed loop can be formed to maintain the pressure of the entire system. When the reversing valve 21 is switched from the test function port to the pressure relief function port 212, the liquid flowing out of the pressure relief function port 212 of the reversing valve 21 can push open the hydraulically controlled one-way valve 27, so that the liquid in the closed loop during the test flows back to the liquid tank 11 through the hydraulically controlled one-way valve 27, completing the pressure relief.

[0062] In some embodiments, the liquid supply module also includes a coarse filter 13 and a fine filter 14. The coarse filter 13 is arranged between the inlet of the liquid supply pump 12 and the liquid tank 11, and the fine filter 14 is arranged on the outlet pipeline of the liquid supply pump 12. The liquid in the liquid tank 11 can be filtered before and after passing through the liquid supply pump 12 to prevent impurities from entering the hydraulic circuit.

[0063] A fourth one-way valve 15 is also provided on the outlet pipeline of the liquid supply pump 12 . The fourth one-way valve 15 is located downstream of the fine filter 14 and is used for one-way control of the liquid flowing to the liquid inlet 211 of the reversing valve 21 .

[0064] The outlet pipeline of the liquid supply pump 12 is also connected to the liquid tank 11 through the second liquid return pipeline 16, and a fourth overflow valve 17 is provided on the second liquid return pipeline 16. Similar to the function of the above-mentioned overflow valve, the fourth overflow valve 17 is used to overflow the excess liquid into the liquid tank 11 when the pressure on the outlet pipeline of the liquid supply pump 12 is too high, so as to play a safety protection role and ensure the safe and stable operation of the test system.

[0065] In some embodiments, the liquid supply module further includes an accumulator 18 , which is connected to a pipeline between a liquid inlet 211 of the reversing valve 21 and an outlet of the liquid supply pump 12 to absorb pressure pulsations and shocks of the test system.

[0066] In some embodiments, Figure 1 As shown, a high-pressure filter 28 is also provided on the liquid inlet pipeline of the test bench, which can perform high-pressure filtration on the liquid entering the reversing valve 21.

[0067] In this embodiment, the accumulator 18 is disposed on the outlet pipeline of the liquid supply pump 12 and downstream of the fourth one-way valve 15. The high-pressure filter 28 is disposed on the pipeline between the liquid inlet 211 of the reversing valve 21 and the outlet of the liquid supply pump 12 and downstream of the accumulator 18.

[0068] Furthermore, to facilitate subsequent maintenance, a second spherical reversing valve 291 is provided on the liquid inlet pipeline of the test bench, and a third spherical reversing valve 292 is provided on the liquid outlet pipeline of the test bench. The second spherical reversing valve 291 is located on the pipeline between the liquid inlet 211 of the reversing valve 21 and the outlet of the high-pressure filter 28.

[0069] In some embodiments, pressure detectors are respectively provided on the liquid inlet and outlet pipelines of the test bench, and the pressure detectors are connected to the control module 3. The control module 3 judges the performance of the tested high-pressure filter station 20 according to the pressure detected by the pressure detectors.

[0070] The pressure detector may include a pressure gauge 41 and a pressure sensor 42 provided on the hydraulic pipeline. The pressure sensor 42 is connected to the pressure gauge 41 and the control module 3 respectively. The pressure sensor 42 may detect the pressure of the pressure gauge 41 and send the detected pressure to the control module 3. The control module judges the performance of the high-pressure filter station 20 under test according to the pressure sent by the pressure sensor 42. At the same time, the control module 3 may also adjust the pressure of the test system according to the pressure fed back by the pressure sensor 42, so as to adjust the test parameters under the test conditions such as high pressure or low pressure, and perform a more accurate test on the high-pressure filter station 20 under test.

[0071] In some embodiments, Figure 2 As shown, the test system also includes a protection module, which includes a protection cover 51 and a protection cover driving mechanism 52. The protection cover 51 is arranged close to the high-pressure filtering station 20 under test, and the protection cover driving mechanism 52 is connected to the control module 3. The control module 3 controls the extension and retraction of the protection cover 51 through the protection cover driving mechanism 52, thereby protecting the high-pressure filtering station 20 under test.

[0072] like Figure 3 and Figure 4As shown, the protection module also includes a water tank 53, which serves as a test carrier of the high-pressure filter station 20 to be tested. A track is laid on the water tank 53, and the protective cover 51 can move forward and backward along the track under the drive of the protective cover driving mechanism 52 to protect the high-pressure filter station 20 to be tested, thereby providing safety protection for the operator of the high-pressure filter station 20 to be tested, and preventing the high-pressure liquid from splashing and causing harm to the operator. The protective cover driving mechanism 52 is, for example, a servo motor.

[0073] The specific working process of the test system is as follows:

[0074] When testing, the equipment is started, and the operator clicks the protective cover opening button on the test bench operation interface. The servo motor receives the signal and the protective cover 51 shrinks. The operator lifts the high-pressure filter station product under test into the protective cover 51 and completes the connection of the liquid inlet and return lines on the test bench. Then, the operator clicks the protective cover closing button on the operation page, and the protective cover 51 extends along the guide rail to protect the high-pressure filter station product under test as a whole.

[0075] The operator clicks the test button on the operation page and follows the pre-programmed test program to control the closing of the electromagnet in the electromagnetic pilot valve of the reversing valve 21 to realize the opening and closing of different functional ports of the reversing valve 21, change the hydraulic circuit to adjust the pressure, and complete the performance test of different test conditions;

[0076] Afterwards, the control module 3 of the test system automatically determines whether the performance of the product is qualified according to the test results; after the determination is completed, the servo motor receives the signal to shrink the protective cover 51, and the automatic test of the tested high-pressure filter station product is completed. After the test of the tested high-pressure filter station product is completed, it can be lifted away as described above, and the next tested high-pressure filter station product can be lifted to the test bench for testing.

[0077] Based on the above-mentioned high-pressure filter station test system, the embodiment of the present application further provides a high-pressure filter station test method, which is applied to the control module 3 in the above-mentioned high-pressure filter station test system, wherein the high-pressure filter station test system includes a control module 3, a liquid supply module and a test bench, the liquid supply module includes a liquid tank 11 and a liquid supply pump 12, and the inlet of the liquid supply pump 12 is connected to the liquid tank 11; the test bench includes a reversing valve 21, the outlet of the liquid supply pump 12 is connected to the liquid inlet 211 of the reversing valve 21, the reversing valve 21 has a plurality of functional ports, the plurality of functional ports include a plurality of test functional ports and a pressure relief functional port 212, the plurality of test functional ports are respectively connected to the liquid inlet of the tested high-pressure filter station 20 through corresponding pipelines to form different test hydraulic circuits, the pressure relief functional port 212 is connected to the liquid tank 11 to form a pressure relief circuit 201, the liquid return port 214 of the reversing valve 21 and the liquid return port of the tested high-pressure filter station 20 are respectively connected to the liquid tank 11, and the control module 3 is connected to the reversing valve 21; the method includes:

[0078] By switching and controlling the reversing valve 21 , multiple test hydraulic circuits and pressure relief circuits of the tested high-pressure filtering station 20 are switched.
