Hydraulic Vane Pump Working
Hydraulic Vane Pump Working. During the working, as the space enclosed by the casing, rotor, and vanes increases, a vacuum generates at the pump inlet. A vane pump is a positive displacement pump that delivers a constant flow rate under different pressure conditions.
Figures 1 and 2 show how the moving cam ring provides variable volume and constant pressure. The vanes are located on the slotted rotor. On the discharge side of the pump, the vane chambers are decreasing in volume, taking fluid out of the pump.
The Schematic Of The Vane Pump Working Principle Is Shown In Figure.
Gear and vane pumps which are pulling suction oil from a reservoir located below them, will have a slight vacuum behind the shaft seal. When this seal becomes badly worn, air may enter through the worn seal. After this, the atmospheric pressure forces the hydraulic fluid into this generated vacuum.

The action of the vane drives out the same volume of fluid with each rotation. Figures 1 and 2 show how the moving cam ring provides variable volume and constant pressure. It has the advantages of compact structure, small volume, stable operation, low noise and long service life, but it also has the disadvantages of complex structure, poor oil absorption performance and sensitive to oil pollution.
On The Discharge Side Of The Pump, The Vane Chambers Are Decreasing In Volume, Taking Fluid Out Of The Pump.
Flow rate ranges between 20 to 9500 lpm A hydraulic pump is a primary part of a hydraulic system that transforms the mechanical energy from an engine or motor into hydraulic energy. As the rotor turns clockwise, the volume between two
The Vanes Are Located On The Slotted Rotor.
A slotted rotor is eccentrically supported in a cycloidal cam. Air may be entering around the pump shaft seal. Causes of destruction of these hydraulic vane pumps and motors in service.
A Vane Pump Is A Positive Displacement Pump That Delivers A Constant Flow Rate Under Different Pressure Conditions.
Our company insists all along the quality policy of product good quality is base of enterprise survival; In some cases vane pumps present a good alternative to gear pumps for pumping relatively low viscosity oils. Because the pump’s two oil suction and two oil pressure zones are radially symmetrical, and the hydraulic pressure acting on the rotor is radially balanced, it’s also known as a.
