Compressor lubrication system

摘要

The stratification of the oil-foam mixture in the shell of a compressor is avoided by enhancing the recirculation vortex in the shell. The enhancement of the recirculation or secondary vortex is achieved by providing a baffle plate at the bottom of the shell which effectively mixes the oil and foam by providing a region near the bottom of the shell in which the fluid is not rotating in a horizontal plane. The non-rotating oil is drawn towards the center of the shell by the centrifugal pressure gradient, thus displacing the foam from the center region of the shell.
