ATOS vane pumps are pumps where vanes in the rotor slots contact the pump casing (stator rings), pushing the sucked liquid from the inlet side to the outlet side.

ATOS vane pump working principle:

When the vane pump rotor 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, then decreases in volume to discharge oil. Two cycles of suction and discharge are completed in one rotation of the vane.

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:

1. Changing the pump's rotation direction changes its suction and discharge direction. Vane pumps have a specified rotation direction and reverse rotation is not allowed. Because the rotor blade slots are inclined, the blades are chamfered, and the blade bottoms communicate with the oil discharge chamber, the throttling grooves and suction/discharge ports on the distribution plate are designed for a predetermined direction of rotation. 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 a 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 blade slots will increase leakage; insufficient clearance will prevent the blades 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 suction difficult; too low a viscosity will result in severe leakage.

The operating principle of the ATOS vane pump is similar to that of a single-acting vane pump, the only difference being that the stator surface is composed 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. 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 of the pump are radially symmetrical, and the hydraulic pressure acting on the rotor is radially balanced, hence it is also called a balanced vane pump.
