Electric pumping pump pumping liquid reasons and solutions

December 22, 2023

Electric pump is usually used for pumping all types of oil products such as cooking oil, gasoline, diesel, lubricants, etc., so also known as electric pump.
Electric pumping pump pumping liquid can not draw the following reasons:
I. Electric pump does not run after receiving power supply 1. The power is off (power is not turned on); The solution is to repair the power (turn on the power).
2. Switch bad or not work; solution is to repair or replace the switch.
3. Brush wear or can not be reset; the solution is to replace the brush or adjust the return.
4. armature or (stator) coil burnout; solution to replace the armature coil in the stator.
5. Stator coil short-circuit; solution such as broken in the presence of welding can be used, or need to rewound.
Electric pump after the power of abnormal sound and does not rotate or turn very slowly 1. Switch contacts burn out; solution to repair or replace the switch.
2 mechanical parts stuck; solution to check and trim the part being card.
3. Into the water pipe or drive shaft debris; solution to clean up debris.
4. A small amount of armature short circuit or open circuit; solution to repair or replace the armature.
5. Low power supply voltage; solution to adjust the power supply voltage.
Third, the motor rotation shaft does not turn 1 coupling (gimbal) damage; solution to exchange coupling (gimbal).
2 shaft thread breakage; solution to replace the shaft or short axis.
Four commutator bad damage or sparks 1 armature short circuit or open circuit; solution to repair the armature.
2. Commutator surface is not smooth; solution to remove debris make the commutator surface smooth.
Vibration, excessive noise or liquid leakage 1 liquid emptying; solution to stop the pump.
2. Motor overload (overload operation) solution; check the liquid viscosity, such as viscosity too high for high viscosity pump, check the head.
3. Bearing wear (such as the ring caused by damage); solution to replace the bearing (replace the ring).
4. Skeleton oil seal worn or damaged due to chemical reactions; solution to replace the skeleton oil seal or seal replacement pump.
