Reasons and solutions to less pressure of sand dredge pump

China Do Pump is a manufacturer of sand pump, dredge pump. electric submersible sand pump and hydraulic submersible dredge pump with relative dredging equipment, such as on board dredge pump, ladder dredge pump, booster sand pump. Sand pump is widely used in mines, geological drilling, coal mines, railways, highways, water conservancy and hydropower, bridges, high-rise buildings, foundation reinforcement and other projects. In order to avoid unnecessary losses to everyone, China Do Pump summarized Reasons and solutions to less pressure of sand dredge pump.

The sand pump or pipeline equipment is not strong, and the pump is not in the cavitation state. The impeller or static unbalance is out of tolerance, the elastic pad damages the bearing damage, and the supply of slurry is short, causing the pump to twitch.
The mismatched characteristics of the pump and pump constitute the pump cavitation, the suction pump circuit or the impeller is blocked, and some of the gas causes the pump to oscillate and noise. The demand is based on the on-site internship situation and detailed disposal. The disposal method is reinforced and fixed, and the cavitation characteristics of the tube pump are adjusted so that the NPSH of the pipeline is greater than the NPSH of the pump, the two-axis concentricity is scheduled, and the impeller or the raw weight is statically balanced to make it qualified.
Replace the new elastic pad with a new shaft mud pump, add the slurry volume or close the small pump outlet valve, and dispatch the pump characteristics to match the pipe characteristics and clean the blockage. In the gas chamber, an exhaust valve is added to clean the gas, and the slurry pump head is lower than the pipeline internship head, and the flow rate of the pump is small, and the NPSH of the pipeline is smaller than the NPSH of the mud pump.
The pump inlet valve is not opened or the valve is damaged to constitute the pump cavitation, the intake pipe system intake, the suction pipe or the impeller block the slurry concentration is too large.
Disposal method: pumping the pump head, creating the pumping equipment of the pumping pump, so that the NPSH of the pipeline is greater than the pump NPSH or the pump for changing the cavitation function with satisfactory pipeline equipment. Open the inlet valve or replace the new valve, clean the inlet edge by sweeping the blockage, lowering the slurry concentration or changing the pump to a larger standard.
