Abstract

The invention discloses a gas compressor with an energy source. The gas compressor comprises a heat regenerator (1), a heater (2), a cooler (3), a controller (5), a gas distributing piston (9), a gas outlet passage (10) and a gas inlet passage (12), wherein the heater (2) is positioned in the center of a whole Stirling engine; the cooler (3) is covered on the shell of the Stirling engine; the heat regenerator (1) is arranged at one end of the heater (2), and the gas distributing piston (9) is communicated with the other end of the heater (2); the gas outlet passage (10) and the gas inlet passage (12) are communicated with the lower space of the gas distributing piston (9); the controller (5) is connected with a linear reciprocating driving mechanism (4) which drives the gas distributing piston (9); and the gas outlet passage (10) and the gas inlet passage (12) are correspondingly provided with an gas outlet control device (11) and a gas inlet control device (13) and are connected with the controller (5) respectively. The gas compressor has the characteristics of simple structure, low cost, high cleanness of compressed gases and the like.

Description

technical field [0001] The invention relates to a gas compressor, in particular to a gas compressor with its own energy source. Background technique [0002] There are many types of air compressors. The common ones can be divided into volumetric compressors and speed compressors according to their working principles. The working principle of positive displacement compressors is to compress the volume of gas to increase the density of gas molecules per unit volume to improve compression. The pressure of the air; the working principle of the speed compressor is to increase the movement speed of the gas molecules, so that the kinetic energy of the gas molecules is converted into the pressure energy of the gas, thereby increasing the pressure of the compressed air. [0003] The reciprocating compressor is a type of positive displacement compressor, and its compression element is a piston that reciprocates in the cylinder. The advantages of reciprocating compressors are as follo...

Problems solved by technology

However, the reciprocating compressor also has the following disadvantages: first, the structure is more complicated, and there are many wearing parts; oil pollution

However, the centrifugal compressor still has the following disadvantages: First, the centrifugal compressor is not suitable for occasions where the gas volume is too small and the pressure ratio is too high; More convenient, but less economical; third, the efficiency of centrifugal compressors is generally lower than that of piston compressors; fourth, due to the high speed of centrifugal compressors, mechanical vibration may occur. In terms of operating characteristics, centrifugal The compressor may experience surge
