Vane Pump Animation

Vane Pump
Vane pump have vanes placed in radial slots cut in the rotor as shown in animation. The vanes are capable of sliding in and out of their slots independently. The rotor with vanes is placed eccentric to the axis of pump casing and this eccentricity makes the device to pump fluid to the output port. If there is no eccentricity no flow is obtained at the output port. Due to the eccentric placement of the rotor there is a variation in the volume swept by each pair of vanes for every revolution of the rotor.

The rotor is connected to the motor with suitable provisions to avoid oil leak. When the rotor turns, the vanes are pulled out of their slots due to centrifugal force produced in the rotating rotor. Centrifugal force makes the vanes to fit closely with the walls of the pump casing so that no space is left in between them which prevent oil from escaping through unwanted paths.

The volume of the chamber found in between two successive vanes increases considerably at the input port. This expansion of volume creates partial vacuum resulting in suction of oil from reservoir. As the rotor turns, the volume reduces at the output port and oil is forced out at an elevated pressure level. Output flow rate can be controlled by altering the eccentricity of the rotor. Vane pumps can produce very high pressure and large discharge rates.
