Problems solved by technology

[0010] In view of the high-speed compressor assembly requirements mentioned in the background technology, and the problem that the blades may be damaged due to vibration after the shaft is started, the present invention provides a self-correcting assembly precision compressor. The self-correcting ring smaller than the impeller forms a seal to the power core, and the self-correcting ring is cut by the impeller self-correcting ring to complete the automatic correction of assembly accuracy during operation

Embodiment 1

[0037] Such as figure 1 As shown, a self-correcting compressor with assembly accuracy includes a housing and an impeller shaft 1 arranged in the middle of the housing. The front end of the impeller shaft 1 is provided with an impeller 2, and an assembly assembly is provided on the outside of the impeller 2. The assembly assembly includes a 2 The self-correcting ring 3 at the front end is provided with a volute 10 on the outer edge of the self-correcting ring 3; The power core of the compressor includes the impeller shaft 1 set in the casing, the impeller shaft 1 drives the impeller 2 to rotate at high speed, and the front end of the casing is closed by the volute 10, and the self-correcting ring is used to fill the gap between the impeller 2 and the volute 10 To prevent the compressed medium from leaking out of the cavity, a self-correcting ring with a better sealing effect is used as the shaft end seal. In this application, the self-correcting ring is made of polymer material...

Abstract

The invention discloses a self-correcting assembly precision compressor, which comprises a casing and an impeller rotating shaft arranged in the middle of the casing, an impeller is arranged at the front end of the impeller rotating shaft, and an assembly assembly is arranged outside the impeller, and the assembly assembly includes The self-correcting ring is arranged at the front end of the impeller, and the outer edge of the self-correcting ring is provided with a volute; wherein, the hardness of the self-correcting ring is smaller than that of the impeller. The self-straightening ring is made of polymer material, which has self-lubricating properties. When the impeller is pre-started, the self-straightening ring will be scraped, so that the self-straightening ring is scraped and corrected according to the "rotation profile" of the impeller, so that the self-straightening The ring is automatically corrected according to the working state of the impeller, eliminating the error generated during the assembly of the compressor and ensuring the overall operation stability of the compressor.

Description

technical field [0001] The invention relates to the technical field of compressor production and manufacturing, in particular to a self-correcting assembly precision compressor. Background technique [0002] The rotor is the core component of the centrifugal compressor, which not only affects the aerodynamic performance of the compressor, but also is an important factor affecting the rotor dynamics of the compressor. The first-stage impeller of the single-shaft cantilever centrifugal air compressor is in the form of a cantilever. The impeller is connected to the main shaft and is driven by the prime mover to perform work. [0003] The existing connection between the impeller and the main shaft is a flange connection, and the impeller is tightened with the pinion shaft by bolts, so that the flange contact surface of the impeller and the pinion shaft generates friction during operation, and this force is used to avoid running The relative displacement that may occur between t...
