Key points for managing ATOS vane pumps:

Besides preventing dry running, overload, air intake, and excessive vacuum, the following should also be noted: Vane pumps

Vane pumps

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

2. 3. **Vannel Pump Assembly:** The distributor plate and stator must be correctly positioned using locating pins. The vanes, rotor, and distributor 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 convert the original suction area into a discharge area for continued use.

4. **Disassembly and Assembly:** Ensure the working surfaces are clean. The oil should be well filtered during operation.

5. **A clearance too large in the vane slots will increase leakage; too small a clearance will prevent the vanes from freely extending and retracting, leading to malfunction.

6. **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. An ATOS vane pump is a pump in which vanes in the rotor slots contact the pump casing (stator rings), forcing the sucked-in liquid from the inlet side to the outlet side.

The operating principle of an ATOS vane pump is similar to that of a single-acting vane pump, the only difference being that the stator surface consists of eight parts: two long-radius circular arcs, two short-radius circular arcs, and four transition curves. Furthermore, 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. 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, thus 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 typically 12 or 16.
