CUT SECTION MODEL OF ROTARY VANE COMPRESSOR





Description:

CUT SECTION MODEL OF ROTARY VANE COMPRESSOR: 
 
A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity.
 
The Operation of Vane Compressor:
 
In an air tool, compressed air enters the inlet port which is plumbed to the smallest compartment of the vane-housing inside. The compressed air should be at least at the minimum operating pressure for that air tool to work properly.
The compressed air is moving from an area of high pressure as it enters the air tool, to an area of relative low pressure, that being back to atmospheric pressure outside the air tool. As the air moves inside the tool, it too moves the vanes.
 
As the shaft in the vane-housing rotates due to the air movement, the vanes inserted into that housing slide in or out, depending on where they are in the cycle.
 
Centrifugal force ensures that the vanes are always keeping contact with the inside of the outer cylinder, creating a seal. This forms air-tight compartments within the vane housing.
 
As mentioned, compressed air always flows from an area of high pressure to an area of low pressure, so the high pressure air in the small vane-compartment wants to get to the larger area vane, and ultimately, out of the tool back to a stable, lower, pressure.
 
The shaft inside of the vane-housing extends through air-tight seals up into the air tool, and is attached to tooling on the end or to gearing of some sort. The result is rotary motion of that tooling.
 
It is made out of Original used part, mounted on Duly Powder coated Steel Frame showing details of all components for demonstration purpose.
