This device is manufactured in accordance with the DL/T662-1999 "Sulfur Hexafluoride Filling and Recovery Device" standard. It consists of a recovery system, a filling system, a vacuum pumping system, a purification system, and a gas storage system, with the following main functions:
Product Features
1. Vacuum pumping and vacuum measurement of the device itself and electrical equipment;
2. Recovery of gas from electrical equipment;
3. Drying and purification of recovered and refilled SF6 gas;
4. Filling SF6 into electrical equipment;
5. Compressing and storing SF6 gas from electrical equipment. Main functions of the recovery device:
Main Product Features:
1. Adopts the system principle of German DILO company, with advanced design, complete functions, reasonable structure, and simple and clear operation.
2. The compression system introduces foreign compression technology with a two-stage single-acting compressor, which can directly compress SF6 gas into liquid state for storage in the SF6 storage tank (or use auxiliary refrigeration for compression and storage), achieving oil-free and rapid recovery of SF6 gas.
3. The vacuum pumping system uses a two-stage rotary vane vacuum pump with fast vacuum rate, and is equipped with an oil return prevention device in the system.
4. The recovery and pressurization system uses a single-stage rotary vane pump (diaphragm pump) with low residual pressure and fast speed.
5. The purification system adopts the filter principle of American Pannier Company, with built-in vacuum electric heating and high-efficiency adsorbent inside the filter, making the purification effect more significant (no frequent replacement of adsorbent required).
6. The electrical system of the device automatically confirms and adjusts the three-phase power supply.
7. The control system of the device uses the latest patented SF6 special valves, which are more reliable than ball valves of similar foreign products.
8. The storage system can be equipped with storage tanks of various specifications and capacities according to user requirements.
9. The equipment is air-cooled and mobile, and can be used without an external water source.
