Scroll type air compressor

Abstract

The application discloses a scroll type air compressor, comprising a housing assembly, a crankshaft assembly with one end arranged in the housing assembly, and a compression assembly arranged on the side, away from the crankshaft assembly, of the housing assembly. The crankshaft assembly comprises a crankshaft body axially arranged in the fixed housing and a sliding sleeve attached to the crankshaft body; the housing assembly comprises a fixed housing provided with an axial through hole inside, and a plurality of pins arranged on the housing at intervals; and the compression assembly comprisesa fixed disc member arranged on one side of the fixed housing, and a movable disc member arranged between the fixed disc member and the fixed housing. According to the scroll type air compressor, a pin ring and a pin are adopted for limiting; a crankshaft and a sliding sleeve are adopted for transmission; and if impurities exist in a compression cavity in the compression process, the movable discmember can deflect reversely to avoid the impurities, so that the stability and reliability of the compressor are improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of air compression equipment, and in particular to a scroll air compressor. Background technique [0002] An air compressor is a device used to compress gas, a device that can convert the mechanical energy of the prime mover into air pressure energy, and is usually similar in structure to a water pump. The scroll air compressor is the latest air compressor developed in recent years. Compared with the traditional air compressor, it has a series of excellent technical performances such as novel structure, small size, light weight, and low noise; but in In the prior art, in order to meet the advantages of small size and few parts, the scroll air compressor must ensure that the orbiting scroll and the fixed scroll are axially closely fitted during the design process, so that there will be no friction during processing and assembly. Grouping, selecting and assembling the components increases t...

Problems solved by technology

The scroll air compressor is the latest air compressor developed in recent years. Compared with the traditional air compressor, it has a series of excellent technical performances such as novel structure, small size, light weight, and low noise; but in In the prior art, in order to meet the advantages of small size and few parts, the scroll air compressor must ensure that the orbiting scroll and the fixed scroll are axially closely fitted during the design process, so that there will be no friction during processing and assembly. Grouping, selecting and assembling the components increases the production cost; in addition, during the long-term operation of the scroll compressor, carbon deposits and impurities will be generated in the compression chamber formed by the movable scroll and the fixed scroll and in the oil pressure system of the compressor , when the impurities increase, the movable and static scroll teeth will be stuck, resulting in high temperature or lockup of the machine, which is not conducive to daily work
