(1) When the humidity sensor or the temperature sensor issues alarm, or the vibration or noise is abnormal when the pump is operated; or when the output water volume decreases and the electric energy consumption increases significantly, the diving sewage pump should be performed immediately.
(2) When some poorly sealed submersible pumps are immersed in water for a long time, even if they are not used, the insulation value will gradually decrease, and it cannot be put into time. Internal insulation disappearance. Therefore, the submersible pump is sometimes not available in the spare effect in the water absorption pond. If the condition is permitted, you can use it outside the pool to set aside. When a submersible pump in the operation fails, immediately stop the machine and then put the backup pump. go.
(3) The submersible pump cannot be opened 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 will return. At this time, it will cause the load when the electric pump starts is too heavy, and the unnecessary impact load is affected. Poor components and damage to the entire electric pump.
(4) After stopping, it cannot be restarted before the motor stops running.
(5) Cut off the power when checking the electric pump.
(6) Do not wash items, swim or put livestock into the water when working in a submersible pump, so as to avoid electric shock accidents occur when the electric pump leaks.
