The difference between ATOS vane pumps and those from other pumps lies in the stator surface, which is composed of eight parts: two long-radius circular arcs, two short-radius circular arcs, and four transition curves. The stator and rotor are concentric. When the rotor rotates clockwise as shown in the diagram, the volume of the sealed working chamber gradually increases at the upper left and lower right corners (the suction zone) and gradually decreases at the lower left and upper right corners (the pressure zone). A sealing zone separates the suction and pressure zones. With this type of pump, each sealed working chamber completes two suction and two pressure actions per rotor revolution, hence the name double-acting vane pump. The two suction zones and two pressure zones are radially symmetrical, and the hydraulic pressure acting on the rotor is radially balanced, hence it is also called a balanced vane pump.

The instantaneous flow rate of a double-acting vane pump is pulsating, and the pulsation rate is small when the number of vanes is a multiple of 4. Therefore, the number of vanes in a double-acting vane pump is generally 12 or 16.

Key points for the management of ATOS vane pumps:

In addition to preventing dry running, overload, air intake, and excessive vacuum, the following should also be noted:

Vane pumps

1. Changing the pump's rotation direction changes its suction and discharge directions. Vane pumps have a specified rotation direction and cannot be reversed. This is because the rotor vane slots are inclined, the vanes have chamfered edges, the vane bottoms communicate with the discharge chamber, and the throttling grooves and suction/discharge ports on the distribution plate are designed according to the predetermined rotation direction. Reversible vane pumps must be specially designed.

2. Vane pump assembly: The distribution plate and stator should be correctly positioned using locating pins. The vanes, rotor, and distribution plate must not be installed backwards. The suction area on the inner surface of the stator is most prone to wear; if necessary, it can be flipped over to make the original suction area the discharge area for continued use.

3. 4. During disassembly and assembly, ensure the working surfaces are clean. The oil should be well filtered during operation.

5. Excessive clearance between the blades and the impeller groove will increase leakage; insufficient clearance will prevent the blades from freely extending and retracting, leading to malfunction.

6. The axial clearance of the vane pump has a significant impact on ηv.

1) Small pumps: 0.015～0.03mm

2) Medium pumps: 0.02～0.045mm

7. Oil temperature and viscosity: Generally, the temperature should not exceed 55℃, and the viscosity should be between 17～37mm²/s. Too high a viscosity will make oil suction difficult; too low a viscosity will result in severe leakage.
