Sealed, self-contained, liquid-cooled, gas compressor

摘要

A completely sealed, self-contained, liquid-cooled gas compressor is disclosed. It is made up of vertically superimposed and motive power connected electric motor, gas compressor and oil pump coaxially positioned within a vertical sealed cylindrical housing providing an oil sump at its lower end. Heat exchanger tubes are mounted within the oil sump and in an externally mounted heat exchanger for cooling the oil in the sump and cooling compressed gas derived from a series of compressor stages. Cooled oil is caused to continuously flow over the electric motor and compressor to provide cooling and lubrication and sealing of compressor pistons. A special type of axial swash or wobble plate compressor is used to obtain coaxial alignment and direct connection of motor driven shafts.
