<p>PROBLEM TO BE SOLVED: To provide a centrifugal compressor whose disassembling works can be performed easily by preventing deposits between the inner surface of a casing and the outer surface of internal assembly from sticking fast. SOLUTION: The casing 1 of a compressor is equipped at one end with an opening 8, in the vertical direction with a fluid inlet passage 5 and outlet passage 6, and internally with an internal assemly 2 which is inserted from the opening 8 and installed removably. A gap 4 is reserved between the inner surface of the casing 1 and the outer surface of the internal assembly 2, and with this gap 4, a plurality of passages 7 furnished in the casing 1 are put in communication, wherein the passages are in axial arrangement of the gap. The passages 7 are in communication to piping connection parts 9 and 10 leading to outside the compressor, and oil or solvent is introduced externally into the gap 4 via passages 7 to flow away the sticking deposit from the gap 4, and because they flow out via other passages 7, the disassembling works are facilitated.</p> |
