15 points in the use of submersible pumps Note

1 WQ submersible sewage pump, JYWQ, JPWQ automatic mixing and submerged sewage pump, AS with automatic cutting submersible sewage pump, QJ deep well submersible pump depth is generally 0.5 ~ 3m, in the water, the vertical lifting, not horizontal Lying, but can not be trapped in the mud.
2 In operation, such as a significant reduction in water, the motor suddenly stopped or abnormal sound to be pumping to check, you must first cut off the power.
3 If the ground is bad, found that the switch, unit or circuit leakage phenomenon, should quickly cut off the power, check the deal.
4 can not be extracted with large amounts of sediment water, especially the use of mechanical seal submersible pump.
5 "open" and "stop" should not be too frequent. Shutdown interval 3-5 minutes after the start.
7 run-time, is strictly prohibited in the wells out of the pool to wash things, wet hands, barefoot not open, off the electrical switch to prevent leakage of the pump.
8 Power supply should be selected according to regulations. If the power supply and water pump far apart, the cable cross-sectional area should be increased, the connector should be as small as possible to ensure that the normal use of the voltage between 342-418V. In order to ensure safety, in the vicinity of the power supply or water pump buried in a dormant more than 1 m iron bar as a ground.
9 can not be dehydrated. If the test machine on the land, the running time shall not exceed 5min. In the pumping process, if the water level declining, be careful not to let the submersible pump running out of the water surface.
10 after the boot, if the pump impeller reverse lead to less water or no water, should be immediately shut down, switch the three-phase core cable in any two-phase wiring can make it out of the water.
11 submersible pump into the water or raised the surface, you must pull the ear rope on the climb, absolutely can not pull the cable.
12 Do not immerse in water for long periods of time, and hang them in a dry and ventilated room.
13 integral sealed box is a key seal components of submersible pump, its good or bad a direct impact on the normal operation of the motor. Submersible pump running 50 h later, it should be put on the ground for inspection.
14 After 1 year of use, the submersible pump should be a comprehensive inspection of the rust and paint rust. 1-2 years later, a large inspection, open all parts for maintenance, scrub, descaling rust, and then re-assembled.
15 after shutdown, the tube must wait for the return of water after the completion of the start. If the water still can not be started after the start, should identify the cause
