Working principle of rotary pump

The working principle of a rotary pump is mainly to change the working volume through the rotation of the rotor and the relative motion between the pump body, thereby increasing the energy of the liquid. Specifically: 12

A rotary pump consists of a stationary pump casing and a rotating rotor, without suction and discharge valves. When the rotor rotates, the side in contact with the liquid directly exerts static pressure energy on the liquid through compression, thereby discharging the liquid. twenty-three

As the rotor rotates, space is left on the other side of the pump body, forming a low-pressure area that allows the liquid to be continuously sucked into the pump.

The working mode of the rotary pump makes it suitable for conveying liquids with high viscosity, lubricity, but without solid particles. In addition, the pressure head of the rotary pump is relatively high, the flow rate is usually small, and the discharge is uniform, which makes it perform well in specific applications. two

Overall, the rotary pump effectively changes the working volume and increases the energy of the liquid through its unique rotation and compression mechanism, thereby achieving the suction and discharge of the liquid.
