When it comes to the use of natural gas, the distance from the natural gas filling station is generally less than 500 kilometers, and the economic scope is within 300 kilometers. The number of gas supply households is 2000-50000, and the gas consumption is 200-5000NM3/h. If the gas consumption is too small or too large, the unit gas cost will increase. Compared with the large investment in natural gas pipeline transportation, the investment in CNG mode is small. Compared with long-distance natural gas pipelines, CNG has a shorter construction period and quicker return of funds. CNG's transmission and distribution pipeline network is the same as the urban pipeline network for pipeline natural gas. After the arrival of long-distance natural gas, the facilities can be used directly.
When the gas bus is opened, the shut-off valve in front of the pressure reducer should be opened slowly to prevent the pressure reducer from malfunctioning due to high pressure shock. The pressure is indicated by the pressure gauge, then turn the regulator adjusting screw clockwise, and the low pressure gauge indicates the required output pressure, open the low pressure valve, and supply air to the working point. When the air supply is stopped, just loosen the regulator adjusting screw, and the low pressure gauge is 0, then close the stop valve, so that the pressure reducer will not be pressurized for a long time. Both the high pressure chamber and the low pressure chamber of the pressure reducer are equipped with safety valves. When the pressure exceeds the allowable value, the exhaust will be automatically opened, and the pressure will be closed automatically when the pressure drops to the allowable value. Do not pull the safety valve at ordinary times.
LNG gasification skid is a natural gas supply system for small and medium-sized enterprise users and large and medium-sized public construction users. It consists of LNG gasifier, LNG unloading booster, BOG heater, EAG heater, and water bath electric heater. , valves, pressure regulators, flow meters, shut-off valves, safety relief valves, odorizers and other key components to provide users with reliable and stable gas supply.
Cryogenic liquid cylinder digital display automatic switching gas manifold (Structural features: liquid cylinder digital display automatic switching gas manifold, specially designed for the use of cryogenic liquid cylinders, the main supply cylinder and backup cylinder are low temperature cylinders, the The series of gas busbars do not require operator debugging, the connection is automatically switched, and it can still work normally even when the electrical system is powered off).
