Composition of CBM compressor process system:

Gas-liquid separation tank, dust removal filter, pressure regulating metering device, buffer tank, coal bed gas compressor, dewatering device, CNG filling column, safety maintenance device for gas filling process equipment, electrical device, CNG pipeline and components, etc.

Structural characteristics:

The special gas compressor has a reciprocating piston structure. The whole machine is mainly divided into two parts: moving parts and fixed parts. It consists of a cooling system, a circuit system, a control system, pipelines and auxiliary machines. The moving parts are composed of crankshaft, connecting rod, crosshead, piston, gas valve and so on. The fixed parts are composed of a fuselage, a middle body, a cylinder head, a cylinder, and a cylinder block.
