Product Description

Micro Mini Rotary Vane Vacuum Pump

Product Feature:

Rotary vane vacuum pumps are widely used in automatic and turbocharged gasoline engines to improve driving comfort; Used for diesel engine to replace mechanical vacuum pump, save energy; For new energy vehicles, such as hybrid vehicles, electric vehicles, fuel cell vehicles, etc.

Scope of application:

New energy electric vehicle brake assist system;
Automatic and turbocharged gasoline engines;
Diesel engine.

Operating Principle:

Based on its internal structure and mechanical motion. Rotary vane vacuum pump is mainly composed of pump body, rotor and rotary vane. The rotor is mounted eccentrically in the pump chamber, and the clearance between its outer edge and the top surface of the pump chamber is very small, usually 2 to 3 microns. The rotor is equipped with a plurality of slides which slide in the rotor groove and remain in contact with the inner wall of the pump chamber, thus dividing the pump chamber into multiple studios of variable volume.

When the rotor rotates, the sliding plate slides along the inner wall of the pump cavity under the action of centrifugal force, forming a crescent shaped space. These Spaces change volume as the rotor rotates. The volume of space connected with the suction port gradually increases, and the gas is inhaled; The volume of space connected with the exhaust port is gradually reduced, and the inhaled gas is compressed and discharged through the exhaust valve 12. In addition, the exhaust valve is usually immersed in oil, and the oil enters the pump chamber through the exhaust valve and the oil hole, forming an oil film that seals the gap between the suction chamber and the exhaust chamber to prevent gas back flow.

Rotary vane vacuum pump working features include:

Fast pumping: can extract a large amount of gas in a short time.
Small size, light weight: suitable for use in limited space.
Low noise: low noise during operation.
Convenient maintenance: simple structure, easy to maintain.
High limit vacuum: can achieve a high vacuum.

Application scenarios include:

Laboratory use: because of its small size, low noise, easy to operate, suitable for use in the laboratory.
Electric vacuum device manufacturing: used to extract gas in the manufacturing process to ensure the vacuum environment of the device.
Thermos bottle manufacturing: In the process of thermos bottle manufacturing, extract the internal air to improve the insulation effect.
Vacuum welding: Provide a stable vacuum environment in the welding process.
Printing, blister, refrigeration equipment repair: widely used in a variety of industrial applications requiring vacuum environment.
