Gas recovery device

The gas recovery device adopts a two-stage single action compressor with foreign compression technology, which can directly compress SF6 gas into liquid and store it in SF6 storage tanks. The refrigeration compressor unit of Copeland, a wholly-owned American company, can also be used to reduce the working pressure of the system through the freezing liquefaction method, achieving fast and oil-free recovery of SF6 gas.

Product Name: Gas Recovery Device

Main functions

1. Vacuumize and measure the vacuum degree of the gas recovery device body, electrical equipment, storage tanks, etc.

2. Recycling SF6 gas from electrical equipment.

3. Dry and purify the recovered and recharged SF6 gas.

4. Recharge the electrical switch with SF6 gas.

5. Compressed liquid storage of SF6 gas.

Components and characteristics

1. Adopting the system principle of the German company OIL, the design is *, with complete functions, reasonable structure, and simple and clear operation.

2. The recycling system adopts a two-stage single action compressor with foreign compression technology, which can directly compress SF6 gas into liquid and store it in SF6 storage tanks. The refrigeration compressor unit of Copeland, a wholly-owned American company, can also be used to reduce the working pressure of the system through the freezing liquefaction method, achieving fast and oil-free recovery of SF6 gas.

3. The vacuum pumping system adopts domestic or imported two-stage rotary vane vacuum pumps with fast vacuum rate, and is equipped with a device to prevent oil return in the system.

4. The recycling and pressurization system adopts a vacuum recycling machine, which recovers residual pressure quickly.

5. The purification system adopts the principle filter of the American company Parnell, and the filter is equipped with built-in vacuum electric heating and high-efficiency adsorbent, making the purification effect more significant (without frequent replacement of adsorbent).

6. Automatic confirmation and adjustment of three-phase power supply for the electrical system of the device.

7. The device control system adopts SF6 dedicated valves.

8. The storage system can be equipped with storage tanks of various specifications and capacities according to user needs.

9. The device adopts air-cooled mobile type, and if it is a water-cooled unit, it can be used without an external water source
