LNG dispensers are fuel fling and metering control equipment for LNG vehicles. The SL-JY1/2 series of new LNG dispensers developed and designed by the company are characterized by simple process, easy operation, antitheft liquid control and fast refiling.
The new LNG dispenser adopts the company's self-developed and designed JCS intelligent electronic control system, which is equipped with as mall real-time operating system and fle system, as well as the use of TCP/lP communication mode. lt has the following advantages:
Friendly human-machine interaction and easy-to-use operation.
Super large storage space, while supporting offline storage of 10,000 transaction records and 20,000 black and white lists.
Mllisecond-evel storage and multi Hevel backup of file data, so that every transaction is traceable. Ethernet communication rates of up to 100M bps or more, guaranteeing real-time uploading of every transaction.
Fast response time, making every operation safer and more reliable.
The use of CPU cards that meet the financial security level
plus gas to guarantee the safety of every user's money.
The main components of an LNG filling machine include a low-temperature stop valve, a low-temperature mass flowmeter, a low-temperature emergency shut-off valve, a liquid phase breakaway coupling, an LNG filling nozzle, a low-temperature check valve, a pressure gauge, a low-temperature pressure-reducing regulating valve, a safety relief valve, an explosion-proof pressure transducer, a gas phase breakaway coupling, an explosion-proof controller, stainless steel low-temperature piping, insulation devices, explosion-proof cables, and a filling cabinet. These components, through the integration of equipment and valve switching, realize the workflows such as LNG filling and metering, vehicle-mounted cylinder gas return metering, emergency shut-off, and safety relief.
