Fountain pump is a special equipment for the fountain, according to the number of head can hit the water corresponding to the height, and then form a fountain. If the fountain pump motor damage will directly affect the use of pumps, then the fountain pump motor damage to how to view it?


Fountain pump motor damage View:

1, check the three-phase power supply is not balanced, such as balance, follow-up process.

2, check the overload protection setting current is not in line with the pump rated current demand, and recognition.

3, cut off the power and admit, loosen the pump installed in the leakage, overload switch box power cord.

4, open the net cover, toggle the impeller to see if it is stuck impeller, such as impeller rotation flexibility, the follow-up process.

5, with a range of 500 volts megohm gauge motor stator winding and cable insulation resistance to the ground, pump operation after submerged pump insulation resistance shall not be less than 50MΩ, and admitted. Such as exceeding 50MΩ, check the switch box overload protection device to set the current.

6, cold insulation resistance is less than 50MΩ, the pump should be removed from the underwater pipelines, put the surface, on dry and ventilated place, and wipe dry pump water.

7, check the pump cable, is not damaged, such as damage to the water from the cable breakage into the stator winding, causing the leakage trip, and recognition.

8, such as the cable is not missing, no damage, check pump external cable and pump own cable connection is not bandaged, is not based on my company's instructions in the way of dressing, tape is not reliable, and recognized.

9, loosen the pump cable and external cable, with a range of 500 volts Megohmmeter measurement of the stator winding insulation resistance of not less than 50MΩ, and recognized, such as less than 50MΩ, available scissors peeled cable pump leads l ~ 2m check to see if there is a drop, if the cable does not fit the needs of clarifying the cable from the convergence of water.
