• Description : What are the advantages and disadvantages of vane pump?
• Location : Taizhou

Overview

• Main advantages:

  1. The output flow rate is more uniform than that of gear pump, with smooth operation and less noise.

  2. Higher working pressure and higher volumetric efficiency.

  3. Single-acting vane pump is easy to realize flow regulation, while double-acting vane pump has long service life due to radial hydraulic pressure balance on the rotor.

  4. Compact structure, small outline and large flow.

  Main disadvantages:

  1. The self-priming performance is worse than that of gear pump, and the requirements for oil suction conditions are stricter. Its rotating speed must be in the range of 500-1500r/min.

  2. It is sensitive to oil pollution. The blades are easy to be killed by impurities in oil and the working reliability is poor.

  3. The structure is more complex, the manufacturing precision of parts is higher, and the price is higher.

  Vane pump are commonly used in medium pressure hydraulic systems and are mainly used for machine tool control, especially double-acting vane pumps, which are widely used in precision machine tools due to small flow pulsation.
