Product details

A rotary vane compressor is a type of positive - displacement compressor that utilizes a unique mechanism to compress gas.

At the heart of a rotary vane compressor is a cylindrical housing. Inside this housing, a rotor is mounted eccentrically. The rotor has several slots along its length, and in these slots, vanes are inserted. These vanes are usually made of a material with good wear resistance and sealing properties, such as carbon - fiber - reinforced plastics or high - quality metals. The number of vanes can vary, but common designs have between 4 and 8 vanes.

The compressor also has an inlet port and a discharge port. The inlet port allows the gas to enter the compression chamber, and the discharge port is where the compressed gas exits. There is also a shaft that drives the rotor, usually connected to an electric motor or other power sources.

Rotary vane air compressors Working Principle

As the rotor rotates within the cylindrical housing (driven by the power source), the vanes are pushed outwards due to centrifugal force. The vanes maintain contact with the inner wall of the housing, creating a series of compartments or chambers.

When the rotor starts to rotate, the volume of these chambers varies continuously. As the chambers move past the inlet port, gas is drawn into the chambers. As the rotor continues to turn, the volume of these chambers decreases because of the eccentric position of the rotor within the housing. This reduction in volume compresses the gas trapped inside the chambers.

Finally, when the compressed chambers reach the discharge port, the high - pressure gas is pushed out of the compressor. The continuous rotation of the rotor and the cyclic formation, filling, compression, and emptying of these chambers result in a steady flow of compressed gas.

Rotary vane compressors Advantages

Compact Design: Rotary vane compressors are known for their relatively compact size. Their simple structure allows them to be easily integrated into various systems where space is a constraint. For example, in mobile applications such as on - board air - conditioning systems in vehicles or portable air compressors, their small footprint is a significant advantage.

Smooth Operation: The design of the rotary vane compressor enables it to operate with relatively low vibration and noise levels. The continuous and smooth rotation of the rotor and the even compression process contribute to this quiet operation. This makes them suitable for applications where noise is a concern, such as in indoor environments like hospitals, offices, or residential buildings.

High - Efficiency Compression: Rotary vane compressors can achieve high - efficiency compression over a wide range of operating conditions. The ability to adjust the vane position and the precise control of the compression process allow for effective energy utilization. They can also handle a variety of gases, including air, refrigerants, and various industrial gases.
