fixed displacement vane pumps for hydraulic presses

These fixed displacement vane pumps are commonly used in hydraulic systems that require a steady flow supply. Unlike variable displacement vane pumps, fixed displacement vane pumps have a fixed displacement and are suitable for applications that require high flow stability.

fixed displacement vane pump Principle:

The operating principle of fixed displacement vane pumps is based on the combination of sliding vanes in the rotor groove and an eccentric structure. Inside the pump body there is an eccentric rotor on which several freely sliding vanes are mounted. When the rotor rotates, the eccentric structure drives the vanes to form a number of sealed chambers with the inner wall of the pump casing, and these chambers alternately complete the suction and discharge process. Due to the special design of the structure, the volume of liquid discharged by the pump is fixed in each rotation cycle, i.e., the flow rate is constant and does not change with the change of load and speed.

Fixed displacement vane pumps are widely used in all kinds of hydraulic systems, especially those industries that require strict and stable flow and pressure. Specific application areas include:

1. Cutting machinery: in precision cutting machine tools, fixed displacement vane pumps for the hydraulic drive system to provide a constant flow, to ensure stable transmission of cutting force, improve work accuracy and productivity.
