发布时间:2020/10/09 News 浏览次数:79

1. Music fountain pump does not spray water, sprays less water, and sprays intermittently. The reasons for this failure may be these: the water suction port of the water pump is exposed, the water suction filter is blocked, the motor is reversed, and the impeller is seriously worn. Corresponding solutions: increase the water level or lower the pump, keep the suction port above 50mm from the water surface; remove the debris adsorbed on the filter; adjust the phase sequence of the motor; check whether the sealing rubber gasket of the docking flange is damaged, and check whether there are foreign objects in the pipeline. Replace and repair the pipeline; replace the severely worn impeller.

2. The problem of inaction of the swing mechanism

The reasons for this kind of problem may be: the underwater swing motor is damaged, the linkage mechanism is broken or falling off. The corresponding solutions are: check whether the motor is burnt out, remove it and replace it; replace the link, repair and adjust it.

3. Frequent tripping of the protection switch:

The possible reasons for this kind of occurrence are: motor overload, three-phase voltage imbalance, motor winding burnout, motor bearing damage and jam, cable leakage. The corresponding solutions are: the current is too large, check the repair of the motor; adjust the power supply voltage; replace the winding if the motor winding is burned out; replace the bearing if the bearing is damaged and stuck; check and repair the cable leakage circuit.
