Description

technical field

[0001] The invention relates to a related device for filling compressed natural gas into a container or discharging it from the container in the international classification F17C, in particular to a compact natural gas compressor. Background technique

[0002] At present, the application of compressed natural gas is becoming more and more widespread, and the technology of natural gas compression is also developing rapidly, but the commonly used ones are large-scale compressors, which are basically evolved from the traditional piston air compressor technology. For example, large-scale compressors: the gas transmission capacity is in 100 metres 3 / min, low-rotation compressor is below 200 rpm or high-rotation compressor is 450-1000 rpm, exhaust pressure is 10-100 gauge pressure medium pressure compressor, and its cylinder position can be divided into: cylinder The cylinders of horizontal compressors and vertical compressors with the center line in the horizont...
