Electric pumping liquid pump electric motor does not run after the electric pump
1. The power is broken (the power is not switched on); the solution is to repair the power supply (turn on the power supply).
2. Brush wear or can not be reset; the solution is to replace the brush or adjust the back.
3. Stator or armature coil burned; the stator coil to replace the armature in solution.
4. Switch contact is bad or not, the solution is to repair or replace the switch.
5. Stator coil short circuit; solutions such as broken in place after welding, or need to rewind.
Electric pumping liquid pump electric pump after the occurrence of abnormal sound and do not rotate or turn very slow
1. Water inlet pipe flow channel or the transmission shaft of the debris; solution to clean up the debris.
2. Armature a few short circuit or open circuit; solution to repair or replace the armature.
3. Low power supply voltage; solution to adjust the positive supply voltage.
4. The switch contact points are burned; solutions to repair or replace the switch.
5. The mechanical part is stuck; the solution is checked and repaired by the card part.
Electric pumping liquid pump electric pump motor rotation and rotation of the shaft does not turn
1. Coupling (universal joint) damage; solution to change the coupling (universal joint).
2. The rotating shaft of the screw thread is broken; the solution is to replace the rotating shaft or short axis.
Electric pump pump | electric pumping pump damage produced the commutator
1. Armature short circuit or open circuit; solution to repair the armature.
2. The surface of the commutator is not smooth; the solution to remove debris to the surface of the commutator surface.
Vibration, noise is too large or leakage
1. Motor overload (overload) solution; check the liquid viscosity, such as viscosity is too large for high viscosity oil pump, check head.
2. Liquid emptying; solution to stop the pump.
3. Bearing wear (such as the damage caused by the seal ring); solution to replace the bearing (replace the sealing ring).
4. The skeleton oil seal is damaged by abrasion or chemical reaction, and the solution is to replace the framework oil seal or replace the non sealed oil pump.
