What does the impeller end pressure head mean? Please explain what the pressure head means here Low head flow....
The centrifugal pump head by Bernoulli equation theory, the centrifugal force power derived basic equations, complex formula, is discussed in detail.
Lift means, unit MHello, centrifugal pump, for example, a brief introduction1. centrifugal pump pressure head, also known as the head, refers to the centrifugal pump unit weight (1N) of the liquid can provide effective energy, generally expressed in H, m units. The head of a centrifugal pump is related to the speed and flow of the pump in terms of its structure, size (blade curvature, impeller diameter), etc.. For a certain pump and speed, the head and flow have a certain relationship.
Influence factor:1, the theoretical flow and blade geometry must be, the theoretical pressure head increases with the impeller speed and diameter.2, the shape of the blade is different, divided into the back, radial and forward 3.In fact, because the flow of liquid in the pump is complicated, it is impossible to theoretically calculate the actual pressure head of the pump, usually measured by experiments.Centrifugal pump type[clean water pump] (made in China code IS, D, Sh),IS- is a single-stage single suction cantilever centrifugal pump, the most widely used, made of cast iron, a full range of lift range of 8~98m, flow range of 4.5 to 360 m3/h
