Sand Dredge Pump Pipeline System Working Point
China dredger sand pump manufacturer
As what we have discussed the total working part to sand dredge pump according to the pipeline length and geodetic head, the H-Q (working head vs pump capacity) curve can show the cross point to pump capacity and working head in the curve, and it is a balance to pump at a steady rotating speed to pump impeller.
The transported medium velocity in this H-Q curve is provided by a certain amount of energy, either by diesel engine or motor engine, the change between pump capacity and the working head, in another way of saying, the curve shows pump are working with larger working capacity at lower head output, and less working capacity vs higher total head.
From the curve to pump capacity and working head, we need to assume some character are stay unchanged, such as pipe diameter, length, elevation, fittings and energy, an increasing pump rotating speed can larger both capacity and head performance.
