The quality of the manufacturing process of the rotor, stator, inner curve, blade and other major components in the vane pump directly affects the performance of the vane pump. The Vickers Vane Pump describes the technical requirements of these main components:

For the rotor, it is necessary to ensure that the blade moves flexibly in the groove without jamming, and the gap between the blade and the distribution plate on both sides is reliable, the parallelism on both sides of the blade groove, the flatness on the entire groove surface, and the vertical of the large end faces on both sides of the groove The degree and surface roughness are required to be higher, and the large cross section on both sides of the rotor and the side distribution plates are relatively slippery. It is necessary to ensure reliable sealing of the gap without scratching the end surface of the distribution plate and the occurrence of the distribution plate. The parallelism, flatness and surface roughness of the large sections on both sides are also required to be high.

For the stator and the inner curve are in close contact with the top of the blade, it is necessary to ensure smooth movement of both, and to ensure reliable sealing. At the same time, it is necessary to ensure that the two sides of the blade are parallel to the end face of the rotor, and the straightness of the curved bus bar in the stator and the sides of the busbar are required. The verticality of the end faces meets high design requirements. The thickness direction of the stator plays a role of ensuring a fixed gap between the distribution plate and the rotor on both sides. If the two sides are not parallel, the blade will be scratched to the end surface of the distribution plate, or the internal leakage is increased, so the parallelism, flatness and surface of the stator end faces are opposite. Roughness raises high technical requirements.

For the blade, it is necessary to flexibly slide in the rotor blade groove, and it must be in close contact with the inner surface of the stator. At the same time, the two small sides should be gap-sealed with the distribution plate, so the parallelism, flatness and top line of the two end faces of the blade The degree and the perpendicularity to the small end faces on both sides must meet the design requirements.

For the distribution plate, it is a part that is close to the end faces of the stator, forms a fixed sealing gap with both end faces of the rotor, and provides a suction and discharge passage for the pump. In addition to having a complicated shape and a lumen passage, it is attached to the stator. The end faces must be reliably sealed to prevent excessive leakage. The core that is attached to the rotor, as the pressure increases, causes the part to flex and deform, and the purpose of reducing the axial gap between the rotor and the rotor is achieved, but in order to prevent the occurrence of the phenomenon of the two, the center of the distribution plate Only the concave is not allowed to be convex, and the center angle corresponding to the gap between the suction and the oil discharge window must be greater than or equal to the central angle between the adjacent two blades, that is, there must be a certain cover, and thus there must be a dead phenomenon.
