During the trial run of the water pump after maintenance, all components of the pump and motor should be inspected again, and the pump should be rotated to check its flexibility of movement. ( Wrong )
Wrong: When testing a pump after maintenance, the key parameters to check include vibration, bearing temperature, the presence of any abnormal noises, pump flow rate, inlet and outlet pressures, and motor current; these parameters are used to assess the performance and condition of the pump. Cranking the pump is a necessary step before starting it, mainly to determine whether the pump can be started.
During the trial run of the water pump after maintenance, all components of the pump and motor should be inspected again, and the pump should be rotated to check its flexibility of movement. (Yes)
Answer: When testing the pump after maintenance, its various components as well as those of the motor should be inspected again, and the pump should be rotated manually to check its ease of rotation. (√)
