The cause of the hot water pump motor, the cause of the hot pump motor

Motor is an indispensable part of in the water pump, if the motor is burnt out, the pump will stop working, we delay the construction period. There are times when we can inspect the workings of the motor, such as touch with hand motor, if it is found that the motor burning should be handled in time, then the motor heating is what reason, we simply list the points today.

electrical heating, hot reason:

1, the motor itself, to the quality of the cooling effect is not good, may be the cause of a hot water pump motor, the motor is quality is bad, this situation should be timely to let factory change.

2, because of the water pump type selection is not correct, high-lift pump low pressure operation, this can result in large water pump outlet flow and make the motor overload, because too much load to increase the power consumption of the machine.

3, insulation level determines the allowed temperature limit of the motor. In IEC60034 - 1 the heat resistance of insulating material, insulation grade calculation method of the partition and overheating.

4, because the delivery have a larger proportion of liquid is high viscosity liquid, choose the pump does not adapt to transport liquid medium, if the proportion is bigger than the water should be increasing the motor power, viscosity is bigger should choose screw pump is more appropriate.

5, the motor of the abnormal vibration or noise is likely to cause fever. This kind of circumstance belongs to cause the vibration of the motor itself, the majority is due to the rotor dynamic balance is not good, as well as the bearing, shaft bending, end cover, frame, the rotor axis of different, fasteners loose or motor installation of foundation caused by uneven, installation does not reach the designated position, or mechanical side passed, will produce noise, vibration will generate additional load.

6, the air gap between stator and rotor is small, easy to cause, collision between the rotor. In the medium and small motors, air gap is commonly 0. 2毫米~ 1。 5mm。 Air gap is big, the required field current is large, which affects the motor power factor; The air gap is too small, the rotor is possible friction or collision.

general due to bearing severe wear out-of-tolerance and end cover inner hole deformation, make the base, the end cover, rotor three different axis caused sweep chamber, it is easy to make motor heating even burned.

fever, hot pump motor solution:

1, the improper selection of lead to the water pump and motor don't match. Should be timely replacement of motor, so as not to burn out.

2, water pump overload, over current running cause fever. Found the water pump superfluid, timely solve.

3, water pump shaft bending or two different axis. Check the replacement pump shaft or adjust the two shaft concentricity.

4, inside the motor bearings, bearing friction heat or rotor parts.

motor heating or burning all of us should value, more should be handled in a timely manner, in order to avoid accidents, consequence is unimaginable.
