Problems solved by technology

[0004] However, the air circuit setting of the existing electric air compressor is unreasonable, the circulation route of the oil-air mixture is relatively short, the contact area between the oil-air mixture and the cooling device is small, and the contact time is short, and the oil-air mixture cannot fully utilize the heat dissipation device of the shell to dissipate heat, resulting in a cooling device. Therefore, the lubricating oil in the oil-air mixture cannot fully contact the cooling device to transfer heat, and cannot fully play the role of the lubricating oil as a cooling medium, resulting in an excessively high internal temperature of the air compressor, which ultimately affects the normal use of the air compressor

Abstract

The invention discloses an air compressor cooling device. The air compressor cooling device comprises an oil gas cooling housing. One end of the oil gas cooling housing is connected to a motor and the other end of the oil gas cooling housing is connected an end cover. A spacer bush is arranged in the oil gas cooling housing. Two ends of the spacer bush are respectively connected to the oil gas cooling housing and an end cover seal. An oil gas cooling chamber is arranged between the spacer bush and the oil gas cooling housing. A compressor is arranged in the oil gas cooling housing. A pressure keeping cavity is arranged between the compressor and the spacer bush. The oil gas cooling housing is provided with an exhaust pipe communicating the compressor and the oil gas cooling chamber. The bottom of the spacer bush is provided with multiple oil gas vents. The bottom of the oil gas cooling housing is provided with lubricating oil. The air compressor cooling device has a simple structure, good lubrication effects, a long oil gas mixture circulation route in the air compressor, a large oil gas mixture-cooling device contact area, long contact time and full heat radiation and solves the problems of the prior art.

Description

Technical field: [0001] The invention relates to the technical field of air compressor oil-gas cooling, in particular to an air compressor cooling device and a cooling method thereof. Background technique: [0002] At present, in the fields of automobile manufacturing, processing centers and construction industries, many jobs are realized by pressure gas, which mainly comes from air compressors. With the extensive development and popularization of electrified equipment, electric air compressors more and more popular. Existing electric air compressors mainly include lubricated and non-lubricated. Among them, the non-lubricated electric air compressor has direct contact with parts and components without the protection of lubricating oil, resulting in fast wear of the compression mechanism and low life. At the same time, due to the lack of lubricating oil The sealing effect of oil-free lubricated electric air compression devices is generally low. [0003] Under the action of ...
