SINGLE SCREW COMPRESSOR AND METHOD OF ASSEMBLING THE SAME

摘要

The present invention provides a single screw compressor wherein a gap between a screw rotor and a casing can be easily adjusted. A single screw compressor (1) comprises a screw rotor (2) and a casing (3), which houses the screw rotor (2). The outer circumferential surface of the screw rotor (2) has a plurality of helical grooves (6). The screw rotor (2) is a tapered rotor whose outer diameter increases from an inlet side toward a discharge side. The casing (3) comprises an outer tube member (21), which has a circular inner hole, and an inner tube member (22). The inner tube member (22) is fixed to the interior of the outer tube member (21). The inner tube member (22) has a tapered inner surface that opposes the tapered outer circumferential surface of the screw rotor (2).
