At present,there are two main principles of sulfur hexafluoride recovery and storage in the world.What are the two?Today Luoyang Phillier special gas and everyone to share.

　　A freezing liquefied method principle:in the process of sulfur hexafluoride recovery purification,under certain SF6 gas pressure,the use of refrigeration units make SF6 gas temperature is reduced to the pressure of saturated steam temperature,SF6 gas to liquid to liquid,and stored in a liquid form,advantage is that recovery is fast,fast liquefaction.

　　Another sulfur hexafluoride recovery and purification using the principle of high-pressure liquefaction method,that is,in the process of SF6 gas recovery,at the ambient temperature at that time,the use of a compressor to increase the SF6 gas pressure to the saturation steam pressure at that temperature,SF6 gas began to be converted into liquid,and stored in liquid form.Advantage is simple,the disadvantage is that the system work pressure,high recovery efficiency is low,when the temperature of the SF6 gas,SF6 gas after compressor compression temperature can reach 80℃above)more than the critical temperature of 45.55℃,cannot make its liquefaction,the high temperature and high pressure of the SF6 gas stayed after a period of time(when the temperature dropped to below the critical temperature would be converted into liquid.

　　At present,oil or no oil system is used in the recovery system,as to which is better,there is a certain controversy.The oil-free system can theoretically achieve 100%SF6 gas does not contact with oil,known as the whole oil,such as the membrane compressor used in China.This kind of sulfur hexafluoride recovery and purification device has large volume,low recovery efficiency and heavy maintenance workload.

　　Luoyang phil's technical service mainly includes the distillation of special gas,permanent gas recovery and purification,and packaging container inner surface processing,the analysis of the sulfur hexafluoride gas detection dawn one-stop solution,gas supply system,etc.,at the same time,agents at home and abroad well-known brands of du jars,valves,pipe fittings,pressure gauge,pressure reducing valve,carburetor,such as equipment,we in line with mutual benefit and reciprocity,The concept of common development,to provide our customers with quality services.
