The Italian ATOS vane pump is a pump in which vanes in the rotor slots contact the pump casing (stator ring), forcing the sucked-in liquid from the inlet side to the outlet side.

Working Principle of the Italian ATOS Vane Pump:

When the rotor of the Italian ATOS vane pump rotates, the vanes, under the action of centrifugal force and pressurized oil, have their tips pressed tightly against the inner surface of the stator. Thus, the working volume formed by the two vanes, the rotor, and the inner surface of the stator first increases in volume to draw in oil, and then decreases in volume to discharge oil. Each rotation of the vanes completes two cycles of oil suction and discharge.

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

Key Management Points for Italian ATOS Vane Pumps:

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

1. When the pump's rotation direction changes, its suction and discharge directions also change. Vane pumps have a prescribed 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 are 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 convert the original suction area into the discharge area for continued use.

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

4. Excessive clearance in the vane slots will increase leakage; insufficient clearance will prevent the vanes from freely extending and retracting, leading to malfunction.

5. 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

6. The temperature and viscosity of the oil should generally not exceed 55℃, and the viscosity should be between 17 and 37 mm²/s. Too high a viscosity will make oil absorption difficult; too low a viscosity will result in serious leakage.
