overview of vane pumps

The vane pump uses the rotating motion of the working impeller to transport the liquid.

Vane pumps can be divided into centrifugal pumps, axial flow pumps, mixed flow pumps and vortex pumps according to their working principles.

The centrifugal pump works by using the centrifugal force generated by the liquid when the impeller rotates;

The axial flow pump works by using the thrust generated by the blades on the liquid when the impeller rotates;

The mixed-flow pump works by using the centrifugal force generated by the liquid when the impeller rotates and the thrust generated by the blades on the liquid;

The vortex pump works by using the vortex motion of the liquid when the impeller rotates.

In petroleum engineering, centrifugal pumps are mainly used in oil field water injection, oil well production, oil product transportation, and as filling pumps for drilling pumps, etc.; axial flow pumps are generally used as circulating water pumps in thermal power stations, oil field water supply pumps, etc.
