Oil-free constant-temperature compressor

Abstract

The invention provides an oil-free constant-temperature compressor. The oil-free constant-temperature compressor comprises a body, a turbine, a piston, a first exhaust valve, a second exhaust valve, a first temperature sensor, a second temperature sensor, a first suction pump and a control module, wherein a compressing chamber, an exhausting chamber, a cooling chamber, a cooling water storage chamber and a gas storage chamber are arranged inside the body. An elastic cushion is arranged inside the oil-free constant-temperature compressor to ensure tight adhesion of the piston to the exhausting chamber so as to prevent leakage of compressed gas; the elastic cushion also can protect the piston, so that abrasion and oiling lubrication during the motion of the piston are avoided, and further oil strains are prevented from entering the compressed gas and completely oil-free gas compression can be achieved. In the oil-free constant-temperature compressor, the compressed gas is cooled in the cooling chamber through cold exchange of a cooling coil, and is then pumped into the gas storage chamber and stored, so that high-temperature storage risks of the gas can be avoided; through arrangement of the cooling water storage chamber, circulating replacement of cooling water can be achieved, so that the cooling effect of the cooling coil is ensured and the cyclic utilization of cooling water is achieved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil-free constant temperature compressor. Background technique [0002] As an important form of energy production, compressors are widely used in all aspects of life, especially in the fields of machinery, metallurgy, electronic power, medicine, packaging, chemical industry, etc., and become the mainstream product of compressed gas. [0003] At present, most of the compressors widely used are oil compressors, that is, the internal parts of the compressor need to be lubricated with oil. In this way, during use, lubricating oil will enter the gas storage tank together with the compressed air, so that the produced compressed gas contains grease, which reduces the purity of the compressed gas. [0004] In addition, during the gas compression process, heat will be generated, which will cause the temperature of the compressed gas to rise. High-temperature gas has a high risk an...

In this way, during the use process, the lubricating oil will enter the air storage tank together with the compressed air, so that the produced compressed gas contains grease, reducing the purity of the compressed gas

[0004] In addition, during the gas compression process, heat will be generated, which will cause the temperature of the compressed gas to rise. High-temperature gas has a high risk and is not conducive to storage and transportation.
