What should I do if the flow rate of the sand pump is insufficient

How to solve the problem of insufficient flow when using a sand pump

If the impeller or the inlet and outlet pipelines are blocked, the impeller or pipelines can be cleaned. If the impeller is severely worn, it should be replaced. If there is air leakage at the packing port, the packing should be compressed tightly.

The power speed of the slurry pump is not matched or the belt slips, resulting in a lower speed. The installation Angle of the axial flow pump blade is too small. Insufficient head, overly long pipeline or right-angle bends in the pipeline; The suction lift is too high; Local blockage or damage to the bottom valve, pipeline and impeller; The outlet pipe is leaking seriously. Troubleshooting method: Restore the rated speed, remove the oil stains on the belt, and adjust the belt tightness properly. Adjust the blade Angle properly, lower the installation position of the water pump, shorten the pipeline or change the curvature of the pipeline. Seal the air leakage point of the water pump and press the packing tightly. Clear the blockage and replace the impeller. Replace the leakage reduction ring and block the leakage point.
