COMPRESSOR CASING, AND METHOD FOR MANUFACTURING THE SAME AND CENTRIFUGAL COMPRESSOR COMPRISING THE SAME

摘要

The present invention relates to a compressor casing, a manufacturing method thereof, and a compressor having the same. According to an embodiment of the present invention, the compressor casing comprises: a fluid suction part partitioning a flow path into which a fluid sucked; a ring protruding part formed to be integrated with the fluid suction part continuously, protruding from the fluid suction part to the outside, and formed to continuously encircle the outer circumference of the fluid suction part; multiple coupling holes formed to reach the inner space of the fluid suction part by penetrating the ring protruding part; and multiple inlet guide vanes coupled to be inserted into the coupling holes, and able to be rotated.
