Working Principle of Opened Type Vane Compressor

Opened Type Vane Compressors are a kind of positive displacement rotary compressor that operate using a set of vanes mounted in a rotor, which rotates inside a cylindrical chamber.

Operating Steps:

  1. Air Intake:
    As the rotor spins, centrifugal force pushes the vanes outward against the chamber wall, creating air-tight compartments between each pair of vanes.

  2. Air Compression:
    As the rotor turns, the volume of each air compartment decreases as it moves through the chamber, compressing the air inside.

  3. Air Discharge:
    The compressed air is then pushed out through the discharge port at the end of the compression cycle, delivering steady, pulse-free airflow.

The open design typically refers to an open-frame construction (without soundproofing enclosure), which allows easy access to internal components for visual inspection, cooling, and maintenance.


Suitable Application Scenarios

The Opened Type Vane Compressor is ideal for stationary industrial environments where reliability, ease of maintenance, and cost-effectiveness are more important than low noise levels.
