Why is the self priming pump unable to fill water?

2024-06-29

Why is the self priming pump unable to fill water? 1. Reasons for the inability of the self suction pump to fill water
If a self priming pump experiences insufficient water supply during use, it is likely due to the following reasons:
1. Damaged shaft seal: The shaft seal is an important sealing component in a self-priming pump. If the shaft seal is damaged, it can cause air to enter the pump, thereby affecting the self-priming effect.
2. Impeller wear: The impeller is a key component in the hydraulic components of a self priming pump. If the impeller is worn, the efficiency will decrease, thereby affecting the water supply capacity.
3. Pump body seepage: Pump body seepage can cause air to enter the pump, affecting the self suction effect and also affecting the tightness of the pump body.
4. Insufficient inlet valve: Insufficient inlet valve of the self suction pump can cause the gas to not be effectively discharged, affecting the self suction effect.
2、 A solution to the problem of insufficient water supply for self priming pumps
1. Replace the shaft seal: If the shaft seal is damaged, it needs to be replaced in a timely manner to ensure the sealing effect.
2. Replace the impeller: If the impeller is worn, a new impeller needs to be replaced to improve the self suction efficiency.
3. Repair the pump body: If the pump body is leaking water, it needs to be repaired to ensure sealing.
4. Increase import valves: If there are insufficient import valves, the number of import valves can be increased to better discharge gas.
In short, the reason for the insufficient water supply of a self priming sewage pump is quite complex, and sometimes it is not simply a problem with the pump body. Users should investigate the specific situation, identify the problem, and promptly handle it.
