Compressor system adopting non-contact type coupling

Abstract

The invention relates to a compressor system adopting a non-contact type coupling. The compressor system comprises a drive motor, a non-contact type coupling driving end, a driving end protective cover, a compressor, a non-contact type coupling driven end and a driven end sealing cover; the non-contact type coupling driving end and the non-contact type coupling driven end are made of permanent magnetic materials; a motor shaft is arranged in the drive motor; the end of the motor shaft is fixedly connected with the non-contact type coupling driving end; a compressor spindle is arranged in the compressor and is connected with the compressor through a bearing; and one end of the compressor spindle is fixedly connected with the non-contact type coupling driven end. The compressor system adoptsa non-contact type driving manner, effectively avoids leakage of media especially a flammable and explosive medium or a toxic or corrosive medium, can improve the safety performance of the compressorsystem, does not need lubricating oil for lubrication, avoids oil utilization and prevents the oil leaking problem.

Description

technical field [0001] The invention relates to a compressor system using a non-contact coupling, belonging to the technical field of compressors. Background technique [0002] Compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is widely used in various fields such as fluid transportation, chemical industry, industrial gas supply, and automobile industry. [0003] Some special fields require the supplied gas to be clean and oil-free. Considering the characteristics of the conveying medium, flammable, explosive, toxic, or corrosive, there are also high requirements for the supply system to prevent leakage. In the existing technology, the direct-connected drive mode is generally adopted, which only relies on the shaft seal seal, which cannot be completely sealed and leak-free; the compressor is lubricated with lubricating oil, and the lubricating oil will enter the medium with the pressure change, which cannot achieve a real seal. no...
