In general, the flow velocity is 2 ~ 3m / s.

Therefore, when designing and selecting the high quality dredge pump model, the flow rate in actual work should match the diameter of the pipeline. If the flow velocity is too high, it will lead to increasing pipeline loss, reducing flow rate, reducing drainage efficiency, and easy blockage of pipes and pumps. In serious cases, it will also cause pipe blockage and high quality dredge pump blockage. If the flow velocity is too low, sedimentation and settling of sand will occur, and the concentration of sediment in the dredge pump chamber will increase sharply, causing the impeller to wear quickly. Unlike the clean water pump, it is not good for high quality dredge pump if the slurry flow velocity in pipeline is too low or too high. When the water contains sand and mud, the slurry flow velocity in the pipeline must be guaranteed. Therefore, the inlet flow should be measured from the two aspects of pipeline and flow velocity. First, considering the inlet flow and pipe diameter: inlet flow = pipe cross-sectional area * flow velocity.

Selecting a suitable high quality dredge pump should consider various factors. How to choose the inlet flow and pipe diameter of high quality dredge pump
