Graphite blades

 

A stator-rotor unit is a main element of a rotary vane compressor where the rotor axis of rotation and the stator axis straddle. The rotor has grooves where graphite vanes are inserted. The graphite vanes allow free movement along the groove surface side guides. The rotor is rotated inside the stator and the graphite vanes move along the groove driven by the centrifugal force and are retained against the stator internal surface. Air compression occurs in cells formed by the stator, rotor and any pair of adjacent vanes, the volume between the cells decreasing in the direction of the rotor rotation with the vanes returning to the grooves. Air compression occurs in cells formed by the stator, rotor and any pair of adjacent vanes, the volume between the cells decreasing in the direction of the rotor rotation with the vanes returning to the grooves. Then the compressed air is forced into the compressed air preparation system unit. In the process of operation the rotor can be heated up to 180º C.

The graphite vanes operate very well in these conditions since the "graphite lube" provides the equipment functional ability with minimum wear in the "dry friction" mode. When using graphite vanes the compressor operation is considerably noiseless.

The Chelyabinsk Prototype Manufacturer Factory fabricates any types of graphite vanes conforming to TU 1915-011-99264460-2013 "Shaped products made of various graphite grades".

The rotary vane compressors are used in: printing industry, compressed air installations, laboratory and dental equipment, control and measuring tools, machine-tool monitors, packaging technologies, computer-based systems.
