The main reasons and exclusion methods of lack of traffic or no water during the operation of submersible pumps:

1. The height of the water pump is too high, so that the impeller is not deep enough, causing the water pump water to decrease. (The allowable deviation of the installation of the water pump installation is not expanded at will)

2. The pump turns opposite. (Pump the motor air -rotating the electric motor first before testing, and check the steering to be consistent with the pump. During the use process, check whether the power supply phase order is changed)

3. The water outlet valve cannot be opened. (Check the valve and often maintain the valve)

4. The outlet pipe road is not smooth or the impeller is blocked. (Clean up the blockage of pipelines and impeller, and often salvage debris in the reservoir)

5. The abrasion -resistant ring of the pump is severely worn or blocked by debris. (Replace the lower wear -resistant ring and clean up the debris)

6. Excessive density of liquids or high viscosity. (Re -equipped with pump class)

7. The impeller falls off or damaged. (Reinstall or replace)

8. When the output of multiple pumps shared by the pipeline, no one -way valve or one -way valve was not sealed. (Install a one -way valve and replace the unidirectional valve seal)
