Vane pump is a kind of hydraulic pump. Vane pump has two types: single-acting pump and double-acting pump. Single-acting pump is generally variable displacement pump and double-acting pump is generally quantitative pump. It is widely used in machine tools, construction machinery, ships, die casting equipment and metallurgical equipment. Because the vane pump has the advantages of uniform output flow, smooth operation, low noise, etc., it is widely used in the hydraulic system of equipment with high operating conditions.

Vane pumps are divided into medium and low pressure vane pumps and high pressure vane pumps according to their working pressure. The working pressure of medium and low pressure vane pumps is generally 6.3MPa, and that of high pressure vane pumps is generally 25MPa to 32MPa.

The common vane pumps are: VQ series, PV2R series and T6 series. When selecting a vane pump, it is necessary to first determine whether to use a fixed displacement vane pump or a variable displacement vane pump, and then make matching purchase according to displacement, pressure, rotation speed, etc.

The biggest advantage of vane pump is low noise and smooth operation. The working condition and environment have a great relationship with the normal operation of vane pump. For example, the vibration of the working environment, dust, iron filings and other impurities may have certain influence on the normal operation of vane pump.

Vane pump requires high purity of hydraulic oil, so machine tool equipment, die casting equipment, injection molding equipment, ships and metallurgy all use vane pump to provide power source for hydraulic system, and vane pump used by construction machinery has strict dustproof and leakage prevention design measures to ensure normal operation of vane pump.
