What are the reasons for the decrease in flow and head of the sand pump during use

What are the reasons for the decrease in flow and head of the sand pump during use?

During the use of the sand pump, the flow rate and head will decrease. What are the factors that cause this phenomenon? The editor of Xi'an HL will explain it.

1. Large particles block the suction pipe and the impeller flow path.

2. The pump speed drops.

3. The impeller is worn.

4. The gap between the impeller and the end face of the pump casing is too large, and the leakage will increase.

5. The opening of the inlet valve is too small.

The decrease in the flow and head of the sand pump will affect the efficiency and service life of the sand pump. How to eliminate these problems so that the sand pump can work normally? Please refer the solutions as following:

1. Remove the blockage.

2. Make the pump run at the rated speed.

3. Replace the impeller.

4. Adjust the gap between the impeller and the end face of the pump casing.

5. Open the large inlet valve.
