Problems solved by technology

[0012] However, the above-mentioned structure has the following disadvantages: if the rotating impeller is stationary, or the stationary impeller is rotating, the nut will be detached from the thread due to inertia during repeated actions.
[0014] However, on the compressor with the above-mentioned structure, when the impeller 30 is stopped by rotation, or is rotated by static, if this action is repeated, the screw 36 on the impeller will move from the screw on the rotating shaft due to inertial factors. drop off on hole 44

Abstract

An installation structure for the impeller of turbine compressor features that the hub of vane wheel has multiple fins formed on its external circumference, a join hole with a projected part on its bottom and the first join part on its inner surface, and the motor shaft has a join axle on its end face for inserting it in said hole, which has a slot on its end face for matching with said projected part and the second join part on its external circumference for matching with the first join part. Its advantages are reliable joint and easy assembling.

Description

technical field [0001] The invention relates to the field of turbo compressors. Background technique [0002] Generally speaking, a compressor is a machine that compresses fluid, and consists of a housing with a certain internal space, a motor installed inside the housing to generate driving force, and a large structure such as a compression component that compresses gas. Compressors that compress fluid are divided into various types according to their compression method. [0003] One of the embodiments of the prior art compressor, the action of the turbo compressor is performed through the following steps. After obtaining the driving force generated by the motor, the impeller rotates, and at the same time, the gas is sucked into the compression chamber where the impeller is installed for gas compression, and the high-temperature and high-pressure gas is discharged. [0004] figure 1 Indicates the compression part for compressing gas in the turbo compressor. As shown in t...
