The operation and scientific research departments of sulfur hexafluoride recovery and purification unit vacuumize various electrical equipment, fill electrical equipment with SF6 gas, recover SF6 gas from the electrical appliances used or tested, and conduct purification treatment, compression and storage to the storage tank.

Sulfur hexafluoride recovery and purification can not only measure the vacuum of the unit and electrical equipment, but also recover the gas in electrical equipment. At the same time, SF6 gas recovered and recharged shall be dried and purified, and SF6 electrical appliances shall be inflated. SF6 gas in electrical appliances can also be compressed for liquid storage. The features of the device are as follows:

(1) The sulfur hexafluoride recovery and purification unit has advanced design, complete functions, reasonable structure and simple and clear operation.

(2) The compression system adopts SF6 special closed compressor without leakage.

(3) The vacuum pumping system of sulfur hexafluoride recovery and purification unit adopts rotary vane vacuum pump, and the system is equipped with automatic oil return prevention device.

(4) The purification system adopts the principle filter of CKD Company of Japan, and the filter adopts electric heating and contains * * * adsorbent, so the purification effect is more significant (no need to change the adsorbent frequently).

(5) Automatic confirmation of three-phase power supply of electrical system of the device and automatic protection of phase failure.

(6) Special valve for sulfur hexafluoride gas used in the control system of the device.
