[0040] The end of the second conduit 43 is arranged in an arc shape, a second connecting hole 45 is arranged in the middle position of the arc-shaped side wall, and a first intelligent valve is arranged in the second connecting hole 45 .

[0046] A connection hole 3 46 is provided at the top of the second conduit 43, and a hose is detachably connected between the connection hole 3 46 and the connection hole 1 34, and a three-way valve is provided at the connection between the hose and the connection hole 1 34, through which the oil flows between the second conduit 43, the hose and the test box 31.

[0047] A vane pump 11 is arranged on the test bearing plate 21, and a test hole 12 and a test hole 2 13 are arranged at the bottom of the vane pump 11. The test hole 12 is sealed and connected to the oil inlet hole 22, and the test hole 2 13 is sealed and connected to the oil outlet hole 23. A test hole 3 14 and a test hole 4 15 are respectively arranged on both sides of the vane pump 11, and both the test hole 3 14 and the test hole 4 15 are matched with the connection hole 2 45.

[0048] In the first embodiment, the vane pump 11 is taken out and placed in sequence according to the setting order of the test bearing plate 21. One vane pump 11 is placed on one test bearing plate 21. When placing the vane pump 11, it is necessary to align the test hole 12 at the bottom of the vane pump 11 with the oil inlet hole 22 on the test bearing plate 21, and align the test hole 2 13 at the bottom of the vane pump 11 with the oil outlet hole 23 on the test bearing plate 21. Before aligning the test holes, a pre-designed sealing ring is placed on the test hole. The function of the sealing ring is to prevent oil leakage when testing the vane pump 11. Since the shape of the test hole 12 and the oil inlet hole 22 fits, and the shape of the test hole 2 13 and the oil outlet hole 23 fits, the installation between the vane pump 11 and the test bearing plate 21 fits, and the first step of installing the vane pump 11 is completed;

[0049] After completing the first step of installing the vane pump 11, the test hole three 14 is aligned with one of the connection holes two 45, and the test hole four 15 is aligned with another of the connection holes two 45. The sleeve 44 drives the conduit two 43 to move toward the vane pump 11 until the arc-shaped area of ​​the conduit two 43 contacts the test hole three 14 and the test hole four 15. Then the connection hole two 45 is docked with the test hole three 14 and the test hole four 15 respectively. A matching sealing ring is also provided at the connection hole two 45, so that the connection between the connection hole two 45 and the test hole three 14 and the test hole four 15 is stronger. At the same time, since the conduit two 43 is a metal pipe, the vane pump 11 can also be clamped through its arc-shaped area, completing the second step of installing the vane pump 11.

[0050] The vane pump 11 is installed in two steps to complete the installation of the test oil circuit of the vane pump 11 and the fixing of the vane pump 11. A vane pump 11 is installed on each test carrier plate 21. The advantage of this test bench 1 is that multiple vane pumps 11 can be tested at the same time, and the overall test of the vane pump 11 can be realized, replacing the sampling detection method.

[0051] The output end of the second motor 24 needs to be connected to the rotor in the vane pump 11 when the vane pump 11 is installed.

[0052] In the second embodiment, when the vane pump 11 is tested, the intelligent valve 1 is closed, the intelligent valve 2 26 and the intelligent valve 3 27 are opened, and the pump 2 is opened. The oil in the storage box 1 5 is pumped into the conduit 4 52 through the pump 2, and enters the oil inlet hole 22 through the conduit 4 52, and then enters the vane pump 11 through the test hole 12 connected to the oil inlet hole 22. As the rotor in the vane pump 11 rotates, the oil is discharged through the test hole 2 13, and is discharged into the conduit 6 62 through the oil outlet hole 23, and finally enters the storage box 2 6 through the conduit 6 62. Since the oil pumped by the pump 2 has high pressure, the oil can directly enter the vane pump 11. A liquid level detector is set in each of the storage box 1 5 and the storage box 2 6. When the liquid level detector in the storage box 2 6 detects that oil has entered, it indicates that the rotor oil guide function of the vane pump 11 is good, and the first step of testing the vane pump 11 is completed.

[0053] Open the smart valve 1, close the smart valve 26 and the smart valve 3 27, open the three-way valve near the storage box 2 6, so that the hose can operate to connect the test box 31 with the conduit 2 43, turn on the pump 1, and pump the oil in the storage box 1 5 into the conduit 3 51 through the pump 1, and then enter the connecting hole 2 45 through the conduit 3 51 and the conduit 2 43, and then enter the vane pump 11 through the connecting hole 2 45 and the test hole 3 14, and the oil is discharged to the test hole 4 15 through the rotor movement of the vane pump 11 itself , the oil is discharged into the hose through the test hole 415, and finally the oil enters the test box 31 until the test box 31 is full of oil. The oil storage value can be checked on the display screen 33. In this process, the output time H of the oil from the storage box 15 to the test box 31 is recorded, including the set oil volume V that can be contained in the test box 31. If the output time exceeds H during the process of filling the test box 31, it means that the oil discharge amount of the vane pump 11 is lower than the qualified value, and the vane pump 11 is judged to be unqualified. If the test box is filled, the output time exceeds H. During the test of 31, if the output duration is lower than H, it means that the oil discharge of the vane pump 11 is higher than the qualified value, and the vane pump 11 is judged to be unqualified. There is a numerical deviation in the H value. If the output duration is H during the process of filling the test box 31, it means that the oil discharge of the vane pump 11 is qualified, and the vane pump 11 is judged to be qualified. The H value recorded in the actual process only needs to be within the numerical deviation range. The worker adjusts the oil discharge of the unqualified vane pump 11 according to the H recorded in the test box 31 to ensure that the oil discharge of each vane pump 11 is accurate. During the test, the problems of each unqualified vane pump 11 are recorded. The worker only needs to make adjustments according to the recorded data. After the test of the vane pump 11 is completed, the three-way valve is adjusted so that the conduit 2 43 is also connected to the storage box 2 6. The oil in the test box 31 flows down through the hose and then enters the storage box 2 6 through the conduit 2 43. The liquid level detector in the storage box 2 6 detects that oil has entered, which means that the rotor oil guide function of the vane pump 11 is good, and the second step of testing the vane pump 11 is completed.

[0054] The first step of testing the vane pump 11 is to detect whether the test holes 12 and 13 on the vane pump 11 are flowing oil normally, and also to detect whether the rotor in the vane pump 11 is operating normally. If this test step fails, there is no need to perform the second step of testing. The second step of testing the vane pump 11 is to detect whether the test holes 3 14 and 15 on the vane pump 11 are flowing oil normally, and also to detect whether the oil discharge volume of the vane pump 11 is accurate. Due to the different ways of using the test holes, a passage detection test is performed on the two connected test holes on one device, and the oil discharge volume of the vane pump 11 is tested at the same time, so as to achieve the purpose of batch testing of the vane pump 11.

[0055] The sensors used in the test process are all advanced sensors, which ensure the accuracy and reliability of the test data. The data processing system of the test bench 1 has powerful data processing and analysis functions, which can monitor the performance of the vane pump 11 in real time and provide corresponding reports and suggestions. The test device of the present invention has the advantages of low cost, easy operation and high test accuracy, and has important practical application value.
