Self-priming pump is a pump that can autonomously draw in liquids when there is no natural drainage. They are also known as automatic suction pumps or self-priming centrifugal pumps.
A centrifugal pump is a pump that operates based on centrifugal force. It is mainly composed of basic components such as the pump casing, impeller, shaft, bearings, and sealing device. The impeller rotates to generate centrifugal force, which causes the liquid to be discharged from the center to the periphery, thereby achieving the transportation of the liquid.
Description
A rotor pump is a type of pump that relies on two rotors rotating in opposite directions synchronously during the rotation process to generate suction (vacuum) at the inlet, thereby drawing in and transporting the material.
The screw pump works by the mutual meshing of the screw and the liner, causing volume changes in the suction chamber and the discharge chamber, thereby transporting the liquid. It is a kind of internal-meshing, closed-type screw pump.
A negative pressure pump is a pump that can suck out the air or gas from the atmosphere or the interior of a vacuum pipeline.
