Motor driven twin screw rotor compressor - is liquid cooled and lubricated by injection into compression chamber

摘要

The motor driven compressor has a screw type compressor cooled and lubricated by a liq. injected in the compression chamber. In the frame, at about mid height, are openings for the screw rotors. Openings above are for an air filter and a liq. collector, both tubular. In a hollow space at the bottom of the frame is a tank for cooling liq. The compressor outlet comes out in this space and the dimensions are carefully chosen to reduce the liq. flow speed. The hhollow space is divided into at least two parts, joined by an opening.
