SLIDING VANE ROTARY COMPRESSORS

A cylindrical rotor turns eccentrically in a cylindrical stator of a larger diameter: the free space left between stator and rotor is half-moon shaped. Some slots are milled in the rotor and stratified plastic blades slide freely into the slots.

The blades, as the rotor turns, are forced out against the cylindrical wall of the stator by centrifugal force, so creating individual cells whose volume reduces from a maximum to a minimum during the rotation. The suction takes place through ports in the stator in the area of increasing volumes; the discharge through ports in the stator in the area of decreasing volumes.

Advantages

The main advantages of using side channel machines are:

•   easy installation;
•   low noise level;
•   no vibration;
•   pulsation free gas flow;
•   minimal maintenance.

Moreover, no internal lubrication is necessary and therefore the gas moving through the machine remains uncontaminated and completely oil-free.

The most common fields of applications

• Landfill biogas recovery to feed torch, burner or gas engine;
• tank, plant or contaminated soil gas recovery to feed torch or burner;
• extraction of biogas from gasometer, natural gas from pipeline or gasometer and burner or gas engine feeding.
