How to make well submersible water pumps work normally?

Floods and submersible pump oil mainly use two types of pumps and motors for the two parts. In order to guarantee the normal operation of the electric pump, must use the following method.1.Pump before use, application, check the motor insulation resistance by megger are the lowest not less than 5 ohms. Check method is connected to the pump in line, other end is connected to the electric room, shaking megohmmeter cable terminal megohmmeter, insulation resistance change.2.Check the cable have craze, the phenomenon such as wear and tear, if any, should be replaced in a timely manner, to prevent leakage.3.Flood irrigation motor bolts should be open, clean water after the screw down the bolt, and then will descend to fill water. Found oil, engine oil, replace the seal element and into the water, and then descend.4.The backing pump water pump should fill in 1 to 2 minutes, with water and air to 2 times, check the idle and start is normal. If closed, on the contrary, after the two phase lines are interchangeable.5.Check whether the crack GuanYang, connection is safe.6.Lift pump into the water or time, do not pull the cable, so the cable damage or disconnect joint.7.Supply voltage should be controlled in less than or less than 5% of the rated voltage range, if the voltage is too high or too low will damage motor.8.Into the water pump should be vertical not diagonal.9.Pump shall not be more water or mud sediment transport. Motor should often clean the water chamber, replace the motor chamber of water.10.Submersible water pump lift should be within the scope of rated head 0.8 1 practice. This will improve the efficiency of the pump, energy saving, to avoid electrical overload operation, to extend the service life.11.Pump after use, should be clean, in a dry place, in the oiled metal surface rust and integrity. Drive the net should be put in the water inside of the machine.
