Rotary Screw

Cut a way HG24Rotary screw packages are cost effective handling a very broad range of applications including wellhead compression, medium pressure gas boosting, vapor recovery, landfill gas recovery and casing head pressure reduction.

Rotary screw compressors use two meshing helical screws, (rotors), to compress the gas. The oil-flooded rotary screw compressor uses lubricating oil to fill the space between the rotors, both providing a hydraulic seal and transferring mechanical energy between the driving and driven rotor.Gas enters at the suction side and moves through the threads as the screws rotate. The meshing rotors force the gas through the compressor, and the gas exits at the end of the screws.

Lubricant is injected into the compression chamber to seal, cool and lubricate. The oil is separated from the discharge stream, then cooled, filtered and recycled.

Reliability, ease of maintenance and minimal service are top design priorities. Lubricant-coolant systems incorporate large reservoirs, circulating pump, properly sized steel heat exchangers, and synthetic lubricant specifically for the gas composition. Standard safety controls monitor lubricant levels, lubricant pressure, suction and discharge pressures as well as compressor discharge temperature.
