How to view the fountain pump motor damage

Fountain pump is special equipment for fountain, on the basis of the head and how much water will play to the corresponding level, and then formed the fountain. If the fountain pump motor damage will directly affect the use of pumps, so, fountain pump motor damage to check how?

Fountain pump motor damage view:

1, check the three-phase power supply is balance, such as balance, the performance of the subsequent process.

2, check the adjusting current overload protector is well pumps rated current demand, and acknowledge.

3, the detection power and recognize, loosen the electric pump leakage, overload switch box installed in the power cord.

4, turn over the net, changing the impeller, see if stuck impeller, such as impeller rotating flexible, performance of the subsequent process.

5, with a range of 500 v megohmmeter measurement of motor stator winding and cable insulation resistance to the ground, electric pump operation pump under water after the insulation resistance shall be not less than 50 m Ω, and acknowledge. Such as beyond the 50 m Ω, check the switch box setting current overload protection device.

6, when the cold insulation resistance is lower than 50 m Ω, should be removed from the underwater pipeline, the pump the water, put in ventilated, dry place, and the moisture of dry pumps.

7, check the electric pump cables, if there is any breakage condition, such as damage to clarify water from cable break into the motor stator winding, leakage tripping, and acknowledge.

8, such as cable shape, there is no damage, check the pumps external cables and water pump with cable connection is bandaging shape, isn't it according to our company to clarify the book needs to dress, fabric is reliable in quality, and acknowledge.

9, loosen the electric pump cable and cable, use range is 500 v measurement electric pump stator winding insulation resistance by megger are not less than 50 m Ω, and acknowledges that such as less than 50 m Ω, use scissors to remove pumps cable lead l ~ 2 m whether there water view, clarify cable wound not fit requirements, if any, from cable to connect into the water.
