Variable Vane Pumps Pilot Operated PV7

Variable Vane pumps Pilot Operated PV7..

The PV7 is a variable displacement vane pump used quite extensively for low to mid-pressure applications for numerous market segments such as machine tool and packaging industries. The PV7 pump utilizes a journal bearing design and pivoting control pistons to provide a low noise and durable product for the industrial hydraulic market.

They basically comprise of housing, cover, rotor, vanes, stator ring, compression spring , set screw  and control plate .
For limitation of the maximum flow, the pump is equipped with a set screw .
The driven rotor  rotates within the stator ring . The centrifugal force presses the vanes  uided in the rotor  against the internal sliding surfaces of the stator ring .

Our pumps are as following :

1.Axial Piston Pumps
2.External gearl pumps
3.Internal gear pumps
4.Gerotor pumps
5.Vane pumps
6.Radial piston pumps
7.Electrohydraulic pumps

The cells  necessary to transport the hydraulic fluid are formed by the vanes , the rotor , the stator , the control plate and the cover .
The cell volume increases by the rotation of the rotor  and via the suction channel , the cells  are filled with hydraulic fluid. When the largest cell volume is achieved, the cells are separated from the suction side.
If the rotor  is rotated further, connection to the pressure side is established, the cells narrow and displace the hydraulic fluid via the pressure channel (P) into the system.

The stator ring  is held in the eccentric initial position by the spring . The maximum operating pressure required in the system is set at the set screw  using the spring .
The pressure building up by the load resistance acts at the pressure side on the inner sliding surface of the stator ring , against the force of the spring .
If the pressure corresponding to the set spring force has been reached, the stator ring is pushed out of its eccentricity in zero position direction. The flow settles at the set value which is just removed. If the peak pressure set at the spring  is reached, the pump controls the flow to almost zero. The operating pressure is maintained and only the leakage is replaced. In this way, the power loss and heating of the hydraulic fluid are kept to a minimum.
