The technician uses a crane to lift the water inlet pipe to the water inlet of the water pump, starts the inlet jack hydraulic pressure 6 to compress the pipe, and installs the outlet water pipe device pipe system 21. Select the appropriate outlet pipe from the rotating disc, take it out and slide it down from the slide platform 26.

Input the basic data of the tested water pump 8 and the test parameters into the PLC control system. The PLC control system automatically determines whether the system is normal and whether the parameters meet the startup conditions. The electronic flow meter 16 obtains the minimum flow of the tested water pump 8. The flow rate points, maximum flow rate points and test points are measured, and the flow rate points are divided equally according to these parameters.
