The userfiles/file/LNG+L-CNGjiaqizhan. pdfLNG+L-CNG station has the function of simultaneously filling LNG vehicle cylinders with LNG and filling CNG vehicle cylinders with CNG in the same station. LNG filling: LNG liquid is pumped from the storage tank to the LNG refueling machine using an LNG low-temperature submersible pump, and then metered and filled into the LNG vehicle steel cylinder. CNG refueling: LNG liquid is pressurized to 20-25MPa using an LNG low-temperature high-pressure plunger pump, and the high-pressure liquid is vaporized into CNG after passing through a high-pressure air temperature vaporizer. It is then metered by a sequence control panel, gas storage cylinder, and refueling machine before being filled into the CNG vehicle steel cylinder
