REGULATOR ASSEMBLY AND CENTRIFUGAL COMPRESSOR

摘要

A regulator structure comprises a vaned diffuser (42), a motor (20), a driving gear (31), a driven gear (32) and a regulation mechanism; the motor (20) is reversible; the regulation mechanism comprises a regulator (41), a supporting member (43) and a regulator sliding member (47); the driven gear (32) is sleeved onto the regulator (41) which is sleeved on the supporting member (43); a long through hole is formed in the driven gear (32), the long through hole extends along the axis of the driven gear (31); the regulator sliding member (47) is fixed to the regulator(41) through the long through hole; the vaned diffuser (42) is fixed to the supporting part; the motor (20) drives the driving gear (31) to rotate, the driving gear (31) drives the driven gear(32) to rotate; the driven gear (32) rotates to push the regulator sliding member (47) to move, the regulator sliding member (47) drives the regulator(41) to rotate relative to the vaned diffuser (42), thus the regulator (41) moves along the axial direction of the regulator, and therefore, regulation in a large range is achieved. And a centrifugal compressor with the regulator is provided.
