In recent years, with the growing energy demand, the dependence on clean energy, especially, has been further expanded. CNG gas, as a clean energy source, is an ideal alternative energy source. It has the characteristics of low cost, high efficiency, no pollution and safe and convenient use. The related technologies have matured over several decades.
Natural gas compressor is the key equipment of CNG filling station, mainly L type, V type, ZW type, which are driven by asynchronous motor crankshaft, and then through the connecting rod, crosshead driven piston in the cylinder reciprocating linear motion to do gas compression, Cooling water is usually cooled by circulating water.
