Avoid using belts, chains, Internal Gear Pumps to directly drive the vane pump when installing the vane pump. It is recommended that the vane pump be driven by a coaxial direct motor, and use flexible connection or spline connection; when connecting with the motor, the vane pump shaft and motor shaft must be within the tolerance range of 0.05mm For the inner coaxial line, a rotary flexible coupling with gap error compensation and angle error compensation should be used. In order to avoid damage to bearings, oil seals, etc., noise, vibration, and even accidents due to the misalignment of the two.

In order to install the spring, the blade of this type of vane pump is thicker, and the top and both sides of the blade are machined to inverted mausoleum or processed into arc-shaped grooves. A cavity is formed on the top of the blade, and the cavity a passes through the hole b and the side groove Or arc-shaped side grooves, which communicate with the root of the blade, ensure the hydraulic balance between the top and root of the blade and the two sides of the blade. When the top of the blade and the arc part on the inner surface of the stator are two large and two small, the transition curve is the same. When in contact, the apexes of the two mausoleums at the top of the blade are in contact.

The reliable seal between the pressure and oil suction area is ensured. When the vane pump blade is in the oil pressure area or the oil suction area, only a mausoleum on the top of the blade is in contact with the inner surface of the stator, so the oil cavity a is in communication with the oil pressure cavity or the oil suction cavity. However, the force balance is maintained. The blades are tightly attached to the inner surface of the vane pump stator by spring force and its own centrifugal force. This structure can increase the blade strength of the vane pump, and also make the contact stress between the stator and the blades small. Suitable for high pressure of Vane Pumps Cartridge Kits.
