Precautions for sewage pumps

(1) When the humidity sensor or temperature sensor emits an alarm, or when there is abnormal vibration or noise during the operation of the pump body; When the output water volume, water pressure drops, and electrical energy consumption significantly increases, the submersible sewage pump should be immediately shut down for maintenance.
(2) When some poorly sealed submersible pumps are immersed in water for a long time, even if not in use, the insulation value will gradually decrease and eventually cannot be put into use. Even in a shorter period of time than the continuous operation of the submersible sewage pump in water, the insulation will disappear. Therefore, sometimes the standby function of a submersible pump in the suction pool cannot be achieved. If conditions permit, it can be dry standby outside the pool. When a running submersible pump malfunctions, it should be immediately stopped and lifted up, and then the standby pump can be lowered again.
(3) The submersible pump should not be started or stopped too frequently, otherwise it will affect the service life of the submersible pump. When the submersible pump stops, the water in the pipeline flows back. If it is restarted immediately, it will cause the load of the electric pump to be too heavy and bear unnecessary impact loads; In addition, frequent starting and stopping of submersible pumps will damage components with poor impact resistance and cause damage to the entire electric pump.
(4) After shutdown, the motor cannot be restarted until it has completely stopped running.
(5) When checking the electric pump, the power must be cut off.
(6) When the submersible pump is working, do not wash items, swim or let livestock enter the water nearby to avoid electric shock accidents caused by electric pump leakage
