Single-cylinder high-pressure air compressor

Abstract

The invention provides a single-cylinder high-pressure air compressor. The air compressor comprises a compressor shell and a compressor body, wherein the compressor shell is of a rectangle body and isformed by the surrounding of a base, a side plate and a top plate; the compressor body is mounted in the compressor shell; the compressor body comprises a power system, a compression system, a cooling system, an oil-water filtering system and a control system; the power system is used for pushing the compression system to generate high-pressure gas; the cooling system is used for cooling the power system, the compression system and the compressor shell; the oil-water filtering system is used for carrying out oil-water separation on high-pressure air; and the control system is used for controlling the starting and stopping of the power system and the cooling system. According to the single-cylinder high-pressure air compressor, a traditional three-stage compression or four-stage compression principle is changed into an integrated two-stage compression principle so as to assist a strong cooling system, so that the high-temperature problem caused due to two-stage compression and integration is solved; and the whole air compressor has the advantages of lightness, low cost and portability.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a single-cylinder high-pressure air compressor. Background technique [0002] In the fields of shooting competition, pressure test, can making, military industry, fire protection and other fields, high-pressure air above 20 MPa will be used. At present, the compressors that provide pressure in the industry have the following shortcomings: [0003] 1. The principle of 3-stage and 4-stage compression is generally adopted, and air cooling is adopted. This kind of compressor has a complex structure and a large calorific value. The external temperature of the compression cylinder reaches 120 degrees, and the internal temperature reaches 200 degrees Celsius. Therefore, the compression cylinder assembly must meet the requirements of high temperature resistance, high pressure resistance, wear resistance and fatigue resistance, and the technical requirements are very high. At present...
