Abstract

The invention discloses an oil-free vortex air compressor. The oil-free vortex air compressor is characterized in that the air compressor comprises a dynamic scroll arranged in a shell and driven by a motor and a static scroll fixed on the shell, the dynamic scroll and the static scroll are respectively provided with mutually engaged scroll teeth which divide the interiors of the dynamic scroll and the static scroll into a plurality of compression chambers with a volume changing with movement of the scroll teeth, the static scroll is provided with one or more than one air vents and an air inlet, and the air vents are communicated with the compression chambers. The oil-free vortex air compressor has the advantages of a simple structure, convenience in installation and usage and a good popularization value.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil-free scroll compressor. Background technique [0002] As the fourth-generation product in the compressor field, with the continuous improvement of processing and testing technology, the promotion of scroll compressors has gradually been recognized by the market. Traditional scroll compressors are mainly used in refrigeration systems such as household air conditioners, car air conditioners, and freezers. The compression medium is refrigerant, and refrigerated oil is attached for lubrication and cooling. The problem of refrigerants is not a new topic. As early as 20 years ago, when scientists confirmed that the use of freon and other substances would destroy the ozone layer in the stratosphere, refrigerants have been plagued by refrigeration and air-conditioning industries. The ozone layer protection treaty was passed in Montreal, Canada in 1987, and the CFC phase-out p...
