Installation procedure of vertical submersible sewage pump

Installation procedure of vertical submersible sewage pump
The pump is installed in the sludge control room, responsible for the sludge pool for digestion.
First, start:
1, starting pump and pump operation, the preheat pool of mud must be more than 2.00M.
2, manual rotation pump spindle, feel should be easy, continuous, uniform rotation, no obvious sense of stuck vibration.
3, open the valve into the mud, and open the pipe into the vent valve and the pump release valve, the internal gas discharge to the vent port of liquid after a continuous uniform off the two release valve.
4, start the motor, observe the current changes and pump starting conditions, to reach the required speed slowly open the mud valve, and adjust to the process requirements.
If the pump in the process of abnormal vibration or current does not meet the requirements of the situation, it is necessary to stop the pump in time to identify the cause, give exclusion and then start again.
Submersible sewage pump start time must be separated by more than 15 minutes.
Second, run:
1, submersible sewage pump operation in the operation of workers should always pay attention to check the operation of the situation, if not normal vibration, noise, air pump should be stopped in time to check. Unstable operation will seriously damage the mechanical seal.
2, to avoid the pump idling, so as not to damage the rubber bearings, and should be avoided for a long time in the closed outlet valve operation.
Second, parking:
1, closed pump outlet pipe valve and pump inlet pipe valve.
Closed power, stop the pump operation
