In the embodiment of the present application, the cylinder 8 is also connected to the test pump 9, so that the test medium in the liquid storage tank 1 flows through the first connecting pipeline 3, the first pressure measuring pipeline 4 and the cylinder 8 in sequence and enters the test pump 9.

[0053] The first connecting pipeline 3 is connected to the inlet of the cylinder 8 through the first pressure measuring pipeline 4, that is, the first pressure measuring pipeline 4 is the pipeline closest to the test pump 9 upstream of the test pump 9.

[0058] Specifically, the flow stabilizer 6 is on the first connecting pipe 3.

[0059] The inlet pipe module further includes a first compensating member 7, which may be a flexible joint, etc., and is not further limited in the present application.

[0060] Specifically, the first compensating member 7 is disposed between the first connecting pipeline 3 and the first pressure measuring pipeline 4, one end of the first compensating member 7 is connected to the first connecting pipeline 3, and the other end is connected to the first pressure measuring pipeline 4. The first compensating member 7 can be provided to relieve the stress on the first connecting pipeline 3 and the first pressure measuring pipeline 4, and can also perform displacement compensation on the first connecting pipeline 3 and the first pressure measuring pipeline 4 to avoid vibration of the first connecting pipeline 3 and the first pressure measuring pipeline 4, thereby improving the working stability of the modular test device.

[0062] The outlet pipeline module includes a second connecting pipeline 12 and a second pressure measuring pipeline 13. The second connecting pipeline 12 and the second pressure measuring pipeline 13 can be stainless steel pipes or carbon steel pipes, etc., and this application does not make further limitations.

[0063] Specifically, in the embodiment of the present application, the test pump 9, the second pressure measuring pipeline 13, the second connecting pipeline 12 and the liquid storage tank 1 are connected in sequence, so that the test medium flowing through the test pump 9 can flow back to the liquid storage tank 1 through the second pressure measuring pipeline 13 and the second connecting pipeline 12.

[0064] The second connecting pipeline 12 is connected to the outlet of the test pump 9 through the second pressure measuring pipeline 13, that is, the second pressure measuring pipeline 13 is the pipeline downstream of the test pump 9 and closest to the test pump 9. Therefore, the second pressure measuring pipeline 13 can be a pressure taking pipeline, and a pressure taking point can be set on the second pressure measuring pipeline 13 to detect the outlet pressure of the test pump, so that the staff can determine the operating status of the test pump 9.

[0065] The outlet pipeline module further includes an outlet valve 14, which may be a ball valve, a solenoid valve or a stop valve, etc., and this application does not make any further limitations.

[0066] Specifically, the outlet valve 14 is disposed on the second communication pipeline 12, and the outlet valve 14 is used to control the on-off state of the second communication pipeline 12.

The second compensating member 15 can relieve the stress on the second connecting pipeline 12 and the second pressure measuring pipeline 13, and can also perform displacement compensation on the second connecting pipeline 12 and the second pressure measuring pipeline 13, thereby preventing the second connecting pipeline 12 and the second pressure measuring pipeline 13 from vibrating, thereby improving the working stability of the modular test device.

[0069] In some possible embodiments provided by the present disclosure, the second connecting pipe 12 includes an adjusting section 121 , the adjusting section 121 is tilted, and the length of the adjusting section 121 is adjustable.

[0070] Among them, for different models of test pumps 9, the height of the position where the outlet of the test pump 9 is located may be different. In order to solve this technical problem, the embodiment of the present application proposes that the second connecting pipeline 12 includes an adjusting section 121, and the adjusting section 121 is tilted. The length of the adjusting section 121 is adjustable so that the downstream pipeline position of the adjusting section 121 of the second connecting pipeline 12 remains unchanged. By adjusting the length of the adjusting section 121, the second connecting pipeline 12 can be connected to test pumps 9 of different models.

[0071] Specifically, the second connecting pipeline 12 further includes a first outlet elbow and a second outlet elbow.

The second end of the regulating section 121 is connected to the second connecting pipeline 12 downstream of the regulating section 121 through the second outlet elbow, and the second outlet elbow can rotate relative to the second connecting pipeline 12 downstream of the regulating section 121. It can be understood that since the first outlet elbow can rotate relative to the second compensating member 15 and the second outlet elbow can rotate relative to the second connecting pipeline 12 downstream of the regulating section 121, the staff can rotate the first outlet elbow and the second outlet elbow and adjust the length of the regulating section 121 to match the second connecting pipeline 12 with the outlet of the test pump 9.

[0074] By arranging the heat exchanger 16 on the second connecting pipe 12 , the temperature of the test medium in the closed circulation loop can be lowered, thereby preventing the water temperature of the closed circulation loop from rising due to long-term operation of the test pump 9 during the durability test, thereby improving the operating stability of the test pump 9 .

[0075] Among them, in the embodiment of the present application, the heat exchanger 16 is a shell and tube heat exchanger 16. The shell and tube heat exchanger 16 can not only cool the closed circulation loop, but also rectify the test medium, play the role of a rectifying grid, and adjust the flow state of the test medium to shorten the length of the second connecting pipeline 12, thereby achieving the purpose of reducing the footprint of the modular test device.
