This device is for those SF6 apparatus and GIS composite apparatus. It can vacuum those apparatus, then fill SF6 gas. It can recover SF6 gas from those apparatus, and clean, compress and store into storage tank. It is comprised of recovering system, filling system, vacuuming system, purifying system and storing system. It may carry out below functions: Vacuum and measure vacuity of itself and apparatus Recovering SF6 gas from apparatus Drying and purifying recovered SF6 gas Filling SF6 gas to apparatus Storing SF6 gas Main features Adopts designing principle from Germany DILO company, advanced design, compact structure, complete function, convenient operation Using dual-grade single action compressor which can compress SF6 gas directly into liquid, so to stored in the tank inside the device Vacuum system adopts dual-grade rotary-vane pump, high vacuuming speed Recovering system adopts single-grade rotary-vane pump (diaphragm pump), low recovery residual pressure, quick speed Filter inside purifying system has built-in vacuum electric heater and high efficient sorbent, better purifying result Adopts patent special SF6 valve, more reliable than ball valves used in overseas similar devices Storing capacity can be as customer's requirement Movable, air cooling, no need water source
