Vane pump working principle and performance characteristics

Vane pump also known as skateboard pump and vane pump. Its main features are compact structure, small size, uniform flow, smooth operation, pulsation and noise, the efficiency is higher than the average gear pump. It is mainly used in machine tools, hydraulic machines, lifting transport machinery, construction machinery and plastic injection machine in the fast, medium-force hydraulic system and lubrication system. Especially in the machine tool is widely used. However, the structure of the vane pump process complex, high precision manufacturing, and parts easily worn. From the perspective of the development trend abroad, part of the vane pump will be gradually replaced by the gear pump during the development of high pressure. Vane pump has a single role vane pump and double-acting vane pump two categories. Double-acting vane pump in the machine about 95% of applications, double-acting vane pump flow, uniformity is better.
