Natural gas filling stations is how to classify? Depending on the size or the general area near the station if there is natural gas pipeline gas station, gas station consulting, can be divided into conventional stations, the master and sub-stations. 1: General Station conventional station was built in the natural gas pipeline through the place has a direct pipeline to take gas from natural gas, natural gas after desulfurization, dehydration and other processes, into the compressor to compress, and then enter the cylinder group or through the sale of gas storage unit filling the vehicle. Usually routine plus standard side air between 600-1000 per hour. 2: The master station master station is built in a temporary place of natural gas pipeline through direct pipeline to take gas from the gas line, after desulfurization, dehydration and other processes gas station, gas station tanks into the compressor compresses the gas station, then enter gas cylinders stored or group of vehicles through the sale of gas to the master machine plus gas, plus the amount of the hourly standard side between 2500-4000. 3: Sub-station sub-station was built in long distance gas pipeline has not been the place, running through the sub-station vehicles (tankers) compressed natural gas discharge column, linkers slaves shipped 25Mpa mother station, and the presence of gas transfer Bottle groups deal in gas filling machine for natural gas vehicles. Sub-station equipment, depending on the driving pressure, there are three common processes. Aerated sub-station compressor ① ② hydraulic sub-station level to push aerated ③ hydraulic piston filling sub-stations. Among them, the compressor for filling sub-stations of the earliest forms of sub-station, the compressor aerated principle some flaws, there are gradually being pushed aerated hydraulic flat sub-station instead of trend. Hydraulic flat push Aerated sub-station was in 2003 introduced a new type of foreign pressurized gas source mode, smooth pressurized gas stations designed to take gas rate, but this time into a larger seed station, need to match the special trailers. Hydraulic piston filling sub-station is a mechanical compressor driven hydraulically driven to a special sub-station compressor. 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 monitors the hydraulic system pressure is low to the high pressure pump to work, PLC automatic control system will open a cylinder valve inlet and outlet valves, high-pressure injection of the liquid medium a cylinder, ensure that the sub-station inside the trailer CNG cylinder gas pressure is 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 vehicles to CNG fuel car with gas.
