Centrifugal pump is one of the simplest parts of equipment. The purpose is for energy to be converted into speed or kinetic energy and pressure to be pumped into the fluid, which is then fed into an electric motor or engine. The energy changes of the pump, impeller and volute are divided into two main parts. The rotary drive energy of the impeller is converted into a part of the kinetic energy. The volute is the rest of the kinetic energy converted into pressure.
The fluid obtains energy in the process of moving through the impeller, and then leaves the outer edge of the impeller at high speed and enters the cochlear pump housing.
Inside the volute, due to the gradual expansion of the flow path, it slows down, and converts part of the kinetic energy into static pressure energy, reaching a higher pressure, and finally flows into the pipeline.
After the liquid received pressure, from the impeller center to the outside flow, the formation of a vacuum in the central position of the impeller, pump suction pipe and the center of the impeller communicated at one end, the other end immersed in the delivery of liquid, through the impeller continuous rotation, will not stop suction and discharge of liquid, mainly rely on the centrifugal force generated by high-speed rotation of the impeller to transport liquid, That's why it's called a centrifugal pump.
