Why is the self priming pump unable to fill water?
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.
