The working principle and main characteristics of centrifugal pump

General centrifugal pump starting pump shell to fill with liquid, when the prime mover and ship drive pump shaft and impeller rotation, the liquid on the one hand with the impeller circular motion, on the one hand under the action of centrifugal force from the impeller center to the periphery, the pump body liquid from the impeller to obtain pressure energy and speed energy. As the fluid flows through the volute to the outlet, part of the velocity energy is converted to static pressure energy. When the liquid is thrown out by the impeller, the central part of the impeller causes a low pressure area, and the suction liquid suction tube surface pressure difference, so the liquid is constantly sucked, and to the circular simple shape, a certain pressure discharge.

Centrifugal pumps compared with other kinds of pumps, with simple structure, can be connected. Directly connected with the motor, not limited by speed, not easy to wear, smooth operation, small noise, uniform water, convenient adjustment, high efficiency, reliable, easy maintenance and other advantages. Among the products of vane pump, centrifugal pump has the largest consumption and the widest range of use. Therefore, centrifugal pumps have been widely used in all walks of life.

The main characteristics of centrifugal pump
1) The flow range of centrifugal pump is very large, generally used in 5~2000m3/h, at present, the largest foreign piece of 54500m/h. In addition, the flow and pressure are smooth, no fluctuation.
2) The centrifugal pump has a higher revolution, which can be directly connected with the motor and steam turbine, 
and the transmission mechanism is simple and tightGet together.
3) Easy to operate and reliable, easy to adjust and maintain, and easy to realize automation and remote operation.
4) Compared with the reciprocating pump of the same index, the centrifugal pump has the advantages of simple and compact structure, small volume, light weight and fewer parts. Easy to manufacture, low cost, and small footprint, so its equipment and repair costs are lower.
