A scroll air compressor

Abstract

The invention discloses a vortex air compressor for improving reliability of compressed air. The vortex air compressor comprises a base, a main shaft, a fixed disc, a movable disc, a movable disc mounting cover, a bearing end cover and a motor. The bearing end cover is used for covering the movable disc and the movable disc mounting cover to prevent external dust or particles from entering the movable disc or the movable disc mounting cover; and the main shaft is connected with the movable disc by penetrating through the main shaft bearing, so that the main shaft is supported by the main shaft bearing during moving, the jitter of the main shaft in moving is effectively limited, the movable disc can eccentrically move stably along a predetermined rail along with rotation of the main shaft, and the reliability of the vortex air compressor is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of air compressors, in particular to a scroll air compressor. Background technique

[0002] The air compressor is the basic product of industrial modernization and the core equipment of the pneumatic system. It is a device that converts mechanical energy into gas pressure energy and is a pressure generating device for compressed air.

[0003] Common air compressors generally include screw air compressors and scroll air compressors. Among them, scroll air compressors have simple structure, small size, light weight, and easy automation because they do not have a reciprocating mechanism. widely used.

[0004] The scroll air compressor is driven by the main shaft to rotate to drive the moving plate to perform eccentric motion, and cooperate with the scroll air compression structure composed of the moving plate and the fixed plate, so that the gas can be gradually compressed to the air outlet hole for output.
