Introduction of commonly used hydraulic vane pump

Common types of hydraulic vane pump:

1. According to whether the flow can be adjusted, it can be divided into: variable pump and quantitative pump.

The output flow that can be adjusted according to the need is called variable pump, and the flow that cannot be adjusted is called fixed pump.

2. According to the commonly used pump structure in hydraulic system, it is divided into three types: gear pump, vane pump and plunger pump.

Gear pump: Smaller volume, simpler structure, less strict requirements on oil cleanliness, and cheaper price; however, the pump shaft suffers from unbalanced force, serious wear, and large leakage.

Vane pump: divided into double-acting vane pump and single-acting vane pump. This pump has uniform flow, smooth operation, low noise, higher operating pressure and volumetric efficiency than gear pumps, and more complex structure than gear pumps.

Plunger pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems; but the structure is complicated, the requirements for materials and processing accuracy are high, the price is expensive, and the cleanliness of oil is required.

Piston pumps are generally used when gear pumps and vane pumps cannot meet the requirements. There are some other types of hydraulic pumps, such as screw pumps, etc., but the application is not as common as the above three.

Taizhou Hongyi Hydraulic Servo Technology Co., Ltd. is the leading manufacturer of high performance vane pumps in China.
