working principle

■ The compressor supplies air to the compressor through the unloading column, and then pressurizes the compressor to a set pressure (18~25MPa) to refill the high and medium pressure gas cylinders. In the process, the gas is sold by the gas distributor. High and medium pressure gas sales are carried out, while low pressure gas sales are completed by direct charging of the trailer. When the trailer pressure is high, the trailer is used to directly charge the medium pressure bottle group.

Product advantages

■ The average exhaust volume is large; the total running time is short; the low-pressure intake section has a large exhaust volume; the low-pressure intake section has a short time; the energy-efficiency ratio in the full unloading stage is high; the adaptive condition change; energy saving.
