What is the working principle of vane pump?

Vane pump working principle is: through an elliptical pump body, the rotor blade is telescopic, in centrifugal force

Under the action of close close in the body of the pump to form a sealed oil chamber, through the large oil chamber inhalation, and then

It is compressed into a small oil chamber and pressed out.

The working principle of

When the vane pump rotor rotates, the blade is under the action of centrifugal force and pressure oil, and the tip is close to the inner surface of the stator. In this way, the working volume formed by the two blades, the rotor and the inner surface of the stator starts from small to large to absorb oil first and then to discharge oil from large to small. When the blade rotates once, oil absorption and oil discharge are completed.

I. working principle of single-acting vane pump

The pump is composed of rotor 1, stator 2, blade 3, oil distribution plate and end cover, etc. The inner surface of the stator is cylindrical. There is eccentricity between rotor and stator. The blade can slide flexibly in the groove of the rotor. Under the action of centrifugal force when the rotor rotates and pressure oil flowing through the root of the blade, the top of the blade is attached to the inner surface of the stator. Thus, a sealed working chamber is formed between two adjacent blades, the oil distribution plate, the stator and the rotor. When the rotor rotates counterclockwise, the blade on the right side of the figure extends outwards, and the volume of the sealing chamber gradually increases, creating a vacuum. Therefore, oil is sucked through the upper window of oil suction port 6 and oil distribution plate 5. On the left. As the blade shrinks in, the volume of the sealing chamber gradually shrinks, and the oil in the sealing chamber is pressed out through another window of the oil distribution plate and oil pressure port 1 and then output to the system. This pump in the process of rotor rotation, oil suction pressure oil once, so called single action pump. The rotor is subjected to radial hydraulic unbalanced force, so it is also called non-balanced pump, its bearing load is large. The displacement of the pump can be changed by changing the eccentricity between the stator and rotor, so this pump is a variable pump.

Vane pump purchase need to pay attention to what? ZHANGFA hydraulic reminder:

1. If it is bulk purchase vane pump, must choose the normal vane pump manufacturers! (e.g. ZHANGFA hydraulic)

2 to buy vane pump must sign a formal contract with the manufacturers!

3. Before purchasing vane pumps in large quantities, the manufacturer must confirm the production of pre-production samples!

ZHAhydraulic taizhou branch specializes in providing vane pump for bulk purchase. Looking forward to cooperating with you!
