Product Introduction Gas vacuum and recharging device using high-quality vacuum pump, with fast pumping speed, no oil smoke, no noise, no drip oil leakage and other advantages, due to the use of closed structure design, avoid external collision, so that the internal pipeline and electrical components can be protected, so that the service life of the machine can be increased, the performance is more superior. Gas vacuum and recharging devices are mainly used in power supply companies, power transmission and transformation engineering companies, power plants, ultra-high voltage transmission and substations, SF6 electrical switch manufacturing plants and other departments, as auxiliary equipment used in the installation, adjustment and maintenance of GCBP, GCBT, GIS and other SF6 electrical products. The device is used to vacuum and recharge SF6 gas operation for the above electrical products, and this device can also be used as a vacuum and recharge gas equipment for other departments.
