Analysis of 6 main failure causes of micro pump

First: when starting the motor does not rotate when the micro pump.

Reason:
1 auxiliary switch DC regulated power supply fault;
2 battery or battery without power is not enough;
3 line contact;
4 motor and carbon brush contact; Second: after the start of the pump motor work but not the water.

Reason:
1 there are debris or particulate impurities in the pump;
2 suction process is higher than the pump rated suction process; Third: traffic shortage. Reason: 1 the actual head of the pump more than the allowable lift; 2 voltage is too low, the motor speed is slow;
3 suction process is too high;
4 air entry into the pipe; Fourth: the flow gradually become small.

Reason:
1 water inlet impurities blocked;
2 filter use time is too long, there is a particle impurity; Fifth: the work of the micro pump water abnormal interrupt.

Reason:
1 motor does not start, the exclusion of circuit fault;
2 pipe plug, remove plug;
3 pipeline rupture, repair welding or replacement;
4 strainer plug, plug removal;
5 water outlet pipe exposed surface; Sixth: the pump is running at the time of violent vibration or noise abnormal increase.

Reason:
1 access voltage higher than the set voltage;
2 mounting angle is not fixed;
3 motor or pump shaft bending.
