Maintenance device for large and super large gas chains.
RF-391 is suitable for large-scale SF6 gas insulated switchgear. It can process 200-500 kilograms of sulphur hexafluoride gas at a time. RF-391 are often used quickly and conveniently during SF6 equipment maintenance, recovery, filtration, storage and refilling. Complete SF6 equipment maintenance safely and quickly.
SF6 gas recovery, liquefied, and storing. The SF6 gas recovery is reduced to <0.1 mbar. Oil-oil suction pump for recovery of SF6 up to 40 m3 / h. Final vacuum <50Pa. Built-in liquid filling machine, filling 70L cylinders for 5 minutes. Re-inject the stored hexafluoride sulfide gas into the switchgear. Filtrated and dried and recovered hexafluoride. Drop the device itself. With digital vacuum gauge or vacuum sensor, the vacuum is accurately displayed. With negative pressure recovery, improve recovery efficiency. Reserved raw material gas stroke bottle interface. Vacuum pump exit is equipped with environmentally friendly emissions.
