发明名称 Shaft isolation seal
摘要 A seal assembly is for a compressor including a casing having first and second chambers and a shaft extending through the casing between the two chambers. The seal assembly includes a main body disposed about the shaft and between the two chambers and having a central axis, an inner surface spaced radially outwardly from the shaft to form a seal chamber. Annular sealing members are connected with the main body and extend radially from the body inner surface toward the shaft, the sealing members preventing flow between the first and second chambers through the seal chamber. A separator is coupled with the shaft adjacent to the main body and has separation passages fluidly connecting one of the two chambers with the seal chamber, each passage extending radially with respect to the shaft axis so as to direct liquids and solids contacting the passage inner surface away from the seal chamber.
