Integrated air compressor

Abstract

The invention provides an integrated air compressor which comprises a machine body, a first-stage cylinder, a second-stage cylinder, a third-stage cylinder, a fourth-stage cylinder, a first-stage gas cooler, a second-stage gas cooler and a combined cooler. The first-stage cylinder, the second-stage cylinder, the third-stage cylinder and the fourth-stage cylinder are fixedly connected with the machine body and distributed in an X shape. The first-stage gas cooler, the second-stage gas cooler and the combined cooler are fixedly connected with the machine body, the first-stage gas cooler is arranged between the first-stage cylinder and the fourth-stage cylinder and in a neutral position, the second-stage gas cooler is arranged between the second-stage cylinder and the third-stage cylinder and in a neutral position, and the combined cooler is arranged between the third-stage cylinder and the fourth-stage cylinder and in a neutral position. The high-pressure gas leakage danger caused when pipelines (including gas paths and cooling water paths) between stages on the air compressor vibrate excessively and are pulled broken can be effectively avoided, and the integrated air compressor has the outstanding advantages of being high in integrity, high in space utilization rate, little in vibration, low in work noise and the like.

Description

technical field [0001] The invention relates to an air compressor, in particular to an integrated air compressor. Background technique [0002] Traditional air compressors, especially high-pressure air compressors, have a complex overall structure design, take up a lot of space, and consume a lot of lubricating oil. In addition, the design method of fastening the host, cooler, and pipelines to the foundation is often used, so , there are many disadvantages when the volume of the compressor unit is small. For example, due to the easy over-positioning during installation, the requirements for matching the compressor unit with the foundation and casing are high. When the cylinder piston of the compressor compresses the gas, the generated The vibration is relatively large, and the vibration will be transmitted to the compressor body, cooler, and pipeline respectively, so that it is easy to crack at the place where the stress is concentrated, which is especially dangerous for hig...

[0002] Traditional air compressors, especially high-pressure air compressors, have a complex overall structure design, take up a lot of space, and consume a lot of lubricating oil. In addition, the design method of fastening the host, cooler, and pipelines to the foundation is often used, so , there are many disadvantages when the volume of the compressor unit is small. For example, due to the easy over-positioning during installation, the requirements for matching the compressor unit with the foundation and casing are high. When the cylinder piston of the compressor compresses the gas, the generated The vibration is relatively large, and the vibration will be transmitted to the compressor body, cooler, and pipeline respectively, so that it is easy to crack at the place where the stress is concentrated, which is especially dangerous for high-pressure pipelines, and the noise of the compressor is relatively large when it is working. In addition, when the compressor unit fails, it is very cumbersome to judge the fault point, and it is difficult to accurately judge which stage of the cylinder and its pipeline are faulty.
