Characteristics of hydraulic oil pump

Hydraulic oil pump is more common in production and life, high work efficiency and strong adaptability make it widely used. On the characteristics of hydraulic oil pump, Xiaobian made a simple summary for everyone.

1. double stage pumping station: when low pressure, high and low pressure pump supply oil at the same time, can obtain larger output flow; when high pressure, low pressure pump unload empty valve automatically return oil without load. Reduce power consumption;

2. hydraulic pump is small in size, light weight, easy to use, high working pressure;

3. single stage pumping station: simple structure, can provide greater working pressure;

4. holding pressure function: in the case of no leakage of the outer oil pump, the pump stops pressure for 5 minutes, the rated pressure drops less than 5Mpa.

Classification of hydraulic pumps:

According to the hydraulic system commonly used in pump structure is divided into: gear pump, vane pump and piston pump 3 kinds.

gear pump

Small size, simple structure, low cleanliness of the oil, the price is cheaper, but the pump shaft by unbalanced force, serious wear, leakage larger.

vane pump

It is divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth running, low noise, higher pressure and volume efficiency than gear pump, and the structure is more complex than gear pump.

Characteristic：

1. the stator adopts advanced high order square no impact transition curve, so that the blade has a good movement and stress state, to ensure the good contact between the blade and stator, and make the flow loss, pressure and flow pulsation is the smallest, lower noise, longer life;

2., the design is reasonable, processing precision circular arc blade, reducing the blade of the stator curve of the compressive stress, improve the life of the stator and blade;

3. using plug-in structure, the main internal parts into components, pump heart replacement can be completed in a few minutes.

Plunger pump

High volume efficiency, small leakage, high pressure, mostly used in high-power hydraulic system; but complex structure, material and machining accuracy requirements, high price, high cleanliness of the oil requirements. The piston pump is usually used when the gear pump and vane pump can not meet the requirements. There are other forms of hydraulic pumps, such as screw pumps, etc., but the application is not as good as the 3 general.
