The working principle of centrifugal pump

centrifugal pump

The working principle of  centrifugal pump is that when pump is filled with water, centrifugal force generated by the rotation of the impeller, the impeller channel water thrown to the periphery by centrifugal force flows into the pump housing, thus reducing the pressure on the center of the impeller, the pressure is lower than the inlet the pressure, the water at this pressure difference flows into the pool by the suction impeller. Such pumps can continue to supply the water continuously.
Addition of the impeller, spiral casing role is also very important. The energy obtained from the liquid in the impeller has a large function outflow impeller, helical liquid which is collected in the pump housing, and at the back of the diffusion tube into pressure energy to kinetic energy.
Compared with other types of pumps, centrifugal pump has a simple structure, easy to wear, smooth operation, low noise, easy to adjust the water evenly, high efficiency, and therefore the centrifugal pump has been widely used.
However, when centrifugal pump in the working process there will be different kinds of loss: mechanical loss, hydraulic loss and volume loss.
