COMPRESSOR END HEAD HEATING ARRANGEMENT

摘要

A compressor end head (200) for providing a thermal barrier near a mechanical seal includes an inner end head (210) and an outer end head (220). The outer end head (220) includes an opening (221) in the center for enclosing the inner end head (210), an outlet (224) and grooves (225) alongside surfaces radially adjacent the opening (221). The inner end head (210) has an opening (211) in the center, an inlet (213), grooves (212) in the opening (211) for enclosing an end portion of a compressor shaft and a flow path along an outer surface.
