Italy ATOS blade pump supply

The working principle of Italian ATOS vane pumps involves two types: single acting and double acting.

A vane pump consists of components such as rotor, stator, blades, oil distribution plate, and end cap. During operation, the tip of the blade is tightly attached to the inner surface of the stator under the action of centrifugal force and pressure oil. The working volume formed by the two blades and the inner surfaces of the rotor and stator first absorbs oil from small to large, and then discharges oil from large to small. When the blades rotate once, they complete one oil absorption and discharge. This type of pump is called a single acting pump because it absorbs oil and pressurizes oil once during each rotation of the rotor. The rotor is subjected to radial hydraulic unbalance force, so it is also known as an unbalanced pump, and its bearing load is relatively high.

The working principle of a double acting vane pump is similar to that of a single acting vane pump, with the difference being the shape of the stator surface and the relative position between the stator and rotor. The stator surface consists of eight parts: two long radius arcs, two short radius arcs, and four transition curves, and the stator and rotor are concentric. When the rotor rotates, the volume of the sealed working chamber gradually increases at the upper left and lower right corners, which are the oil suction area, and gradually decreases at the lower left and upper right corners, which are the oil pressure area. There is a sealing area between the oil absorption area and the oil pressure area to separate them. This type of pump is called a double acting vane pump because each sealed working chamber completes two oil suction and pressure actions for each rotation of the rotor.

The characteristics and functions of Italian ATOS vane pumps mainly include the following aspects:

Working principle: The working principle of ATOS vane pump is based on the fact that when the rotor rotates, the tips of the blades are tightly attached to the inner surface of the stator under the action of centrifugal force and pressure oil. The working volume formed by the two blades and the inner surfaces of the rotor and stator first absorbs oil from small to large, and then discharges oil from large to small. When the blades rotate once, they complete two oil suction and discharge operations.

Type: There are mainly two types of ATOS vane pumps, namely single acting vane pumps and double acting vane pumps. The characteristic of a single acting vane pump is that the rotor is subjected to radial hydraulic unbalanced forces, so it is also known as an unbalanced pump, and its bearing load is relatively large. Changing the eccentricity between the stator and rotor can change the displacement of the pump, so these pumps are all variable displacement pumps. The characteristic of a double acting vane pump is that for every rotation of the rotor, each sealed working chamber completes two oil suction and pressure actions, hence it is called a 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, so it is also called a balanced vane pump.

Performance characteristics: The ATOS vane pump has a high power to weight ratio, with a pressure of 210-300 bar and 13 displacement options ranging from 16 to 150 milliliters per revolution. In addition, it also features a 12 blade rotor with an eccentric cancellation structure, which can reduce output pulsation and noise.

Application areas: ATOS vane pumps are widely used in fields such as steel, metallurgy, power, injection molding machines, air conditioning production, and automotive manufacturing.

In summary, the Italian ATOS vane pump plays an important role in multiple fields with its design and excellent performance.

The following are the precautions for using the Italian ATOS vane pump:

Pump direction: Vane pumps have a specified direction and are not allowed to reverse. Because the rotor blade slots are inclined, the blades are chamfered, and the bottom of the blades is connected to the oil discharge chamber, the throttle slots and suction and discharge ports on the oil distribution plate are designed according to the predetermined direction. Reversible vane pumps must be specifically designed.

Assembly precautions: During assembly, the oil distribution plate and stator need to be correctly positioned with locating pins, and the blades, rotor, and oil distribution plate must not be installed upside down. The suction area on the inner surface of the stator is the most susceptible to wear. If necessary, it can be flipped and installed to turn the original suction area into a discharge area for continued use.

Precautions for disassembly and assembly: When disassembling and assembling, pay attention to the cleanliness of the working surface, and filter the oil well during operation.

Gap between blade and blade groove: If the gap between the blade and the blade groove is too large, it will increase leakage, while if it is too small, the blade cannot expand and contract freely, which can lead to abnormal operation.

Axial clearance: The axial clearance of a vane pump has a significant impact on volumetric efficiency.

Oil temperature and viscosity: The temperature and viscosity of the oil should generally not exceed 55 ℃, and the viscosity requirement is between 17-37mm2/s. If the viscosity is too high, it will be difficult to absorb oil; If the viscosity is too low, there will be severe leakage.

Prevent dry running and overload: Prevent dry running and overload.

Prevent inhalation of air and excessive inhalation of vacuum: Prevent inhalation of air and excessive inhalation of vacuum.

Check the air gap: Regularly check if the air gap is reasonable.

Cleaning the filter: Regularly clean the filter and replace consumables.

Prevent external impurities from entering: Pay attention to preventing external impurities from entering the reserved ports or other pipelines of the equipment.

The above are the precautions for using the Italian ATOS vane pump, hoping to be helpful to you.
