Hydraulic filling sub-stations: CNG sub-stations trailer arrived CNG filling sub-station, through high pressure quick connector inlet hose, high pressure hydraulic hose back control gas tubes, CNG high pressure outlet hose and hydraulic sub-stations pry body connection. After connecting the hydraulic system starts to pry the body or sub-station in the PLC control system to monitor the gas station design of the hydraulic system pressure is low, the high-pressure pump to work, PLC automatic control system will open a cylinder inlet valve and outlet valve, high-pressure injection of a liquid medium cylinders, CNG sub-stations to ensure the trailer within the cylinder gas pressure was maintained at 20-22Mpa, CNG cylinders through the outlet after outlet CNG high pressure hose into the sub-station pry body buffer tank, high pressure pipe delivered to CNG filling Machine-fuel vehicles to CNG filling. General Station: Gas stations cited MV gas pipeline network, metered into the dryer filter after the gas station, gas station storage tanks, after drying, after entering the compressor through a buffer tank pressurized gas stations, by priority / order of the control panel to set the filling gas storage wells, or transported directly to the filling machine for filling CNG fuel vehicles can also take advantage of natural gas wells within the group by filling machine for filling CNG fuel vehicles.
