ATOS/Italian Atos

The 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.

The ATOS vane pump consists of components such as rotor 1, stator 2, vanes 3, distribution plate, and end covers. The inner surface of the stator has cylindrical holes. There is an eccentricity between the rotor and the stator. The vanes can slide flexibly in the rotor slots. Under the centrifugal force of the rotor rotation and the pressure of the oil flowing into the vane roots, the vane tips are pressed tightly against the inner surface of the stator, thus forming sealed working chambers between two adjacent vanes, the distribution plate, the stator, and the rotor. When the rotor rotates counterclockwise, the vanes on the right side of the diagram extend outwards, the volume of the sealed working chambers gradually increases, creating a vacuum, and thus drawing oil in through the suction port 6 and the window on the distribution plate 5. On the left side of the diagram... As the blades retract, the volume of the sealed cavity gradually decreases. The oil in the sealed cavity is forced out through another window on the distribution plate and pressure port 1, and output to the system. This type of pump performs one suction and one discharge cycle per rotor revolution, hence it is called a single-acting pump. The rotor is subjected to radial hydraulic imbalance force, therefore it is also called an unbalanced pump, and its bearing load is relatively large. Changing the eccentricity between the stator and rotor can change the pump's displacement; therefore, these pumps are all variable displacement pumps.

Key Management Points for ATOS Vane Pumps:

In addition to preventing dry running, overload, air intake, and excessive vacuum, ATOS vane pumps should also pay attention to the following:

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

2. 3. **Assembly of the vane pump:** 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. **Clearance:** Too large a clearance in the vane slot 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:** 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 cause serious leakage. In addition to preventing dry running and overload, preventing air intake, and preventing excessive vacuum, the following should also be noted: Vane pump

Vane pump

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 significant leakage.
