Abstract

The invention discloses a segmented mandrel body, an end-toothed disc, a locking nut, a combined mandrel and a compressor set, and belongs to the technical field of hundred-thousand air separation compressor sets. The segmented mandrel body comprises a first-section shaft, a second-section shaft, a third-section shaft, a fourth-section shaft, a fifth-section shaft, a sixth-section shaft, a seventh-section shaft, an eighth-section shaft and a tail shaft from right to left in sequence. The end-toothed disc comprises a stepped shaft type body. The locking nut comprises a sleeve. The impeller combined mandrel comprises the mandrel body, the end-toothed disc, the locking nut and an impeller. The compressor set comprises the impeller combined mandrel. The distance between the right end of the locking nut and the left end of the end-toothed disc can be finely adjusted by rotating the locking nut, so that the stability of the impeller between the locking nut and the end-toothed disc is further improved, that is, the axial stability of the impeller is better.

Description

technical field [0001] The invention relates to the technical field of 100,000 air separation compressor units, in particular to a segmented mandrel, an end sprocket, a lock nut, a combined mandrel and a compressor unit. Background technique [0002] The compressor unit is the "heart equipment" that provides power for the entire coal chemical process. The 100,000 air separation compressor unit refers to the compressor unit that produces 100,000 standard cubic meters of oxygen products per hour. [0003] Centrifugal compressor is a kind of vane rotary compressor. In recent years, due to the development of chemical industry, the establishment of various large chemical plants and oil refineries, centrifugal compressor has become the key to compress and transport various gases in chemical production. Machines play an extremely important role. [0004] Centrifugal compressor working principle: The motor drives the compressor shaft and impeller to rotate at high speed through the...
