ABSTRACT:
An air/oil separator used with a closed loop oil seal system for a liquid ring vacuum pump, which incorporates a multi-chambered design for facilitating multiple stages of oil particulate separation is disclosed. The separator includes a cylindrical multi-chambered accumulator and a cylindrical filter housing, which supports a conventional filter element. The accumulator has an outer housing and an inner housing, which defines an outer reservoir chamber and an inner reservoir chamber. The accumulator also includes an inner oil conduit extending through the inner reservoir chamber, which deposits the oil discharge into the inner reservoir chamber. A perforated inner baffle is mounted within the inner housing to partially divide the inner reservoir chamber. A second outer baffle is mounted inside the outer reservoir chamber between the outer and inner housings to partially divide the outer reservoir chamber. The inner housing has a vent formed near the inlet (proximal) end of the separator, which allows oil mist to pass from the inner to the outer reservoir chamber.
