LNG filling stations are divided into four types, generally including skid mounted filling stations, standard filling stations, L-CNG filling stations and mobile skid mounted filling stations. LNG skid mounted filling device is a highly integrated equipment developed separately for LNG filling of vehicles. The equipment is divided into three parts: liquid storage tank and process equipment skid, liquid dispenser and control duty room, which can facilitate flushing and filling. The equipment is composed of unloading part, pressurizing part, liquid storage tank part, submersible pump part, gas selling machine part, safety control part and duty container part. The equipment has the advantages of high integration, convenient installation, quick unloading and installation, fast filling speed, complete safety facilities and high automation.
Process Description: the LNG dosing device is an immersion cryogenic liquid pump, which has the characteristics of long continuous operation time and zero leakage. The liquid LNG is directly pressurized and delivered to the liquid dispenser to directly flush the vehicle mounted cryogenic bottle, providing stable and efficient energy for the vehicle. The integrated skid mounted LNG liquid adding device developed by our company integrates the functions of pressurization, liquid adding, gas return, unloading pressurization, EAG, etc. on one skid to realize a fast and flexible liquid adding mode.
