SF6 Gas Liquid Full-Function Recovery Device
I. Device Introduction
Based on the power industry standard DL/T 662-1999 "Technical Conditions for Sulfur Hexafluoride Gas Recovery Devices" and the former Ministry of Machinery and Electronics JB/DQ2588-90 "Sulfur Hexafluoride Inflation and Recovery Device" standard, our company has independently developed the YDL-RPSF6 series SF6 gas recovery and inflation device, with key main components imported. This device possesses the essential functions of general SF6 gas recovery and inflation devices, such as vacuuming, inflation, recovery, and storage.
II. Device Features
1. Adopts the design principle of cryogenic liquefaction, reducing the system's working pressure and greatly improving recovery efficiency.
2. The SF6 compressor is a Copeland semi-hermetic compressor, applied to halogen gases such as SF6, with fluorine resistance characteristics, ensuring no leakage.
3. The dual-container system features an SF6 vaporization method, using higher-temperature, high-pressure SF6 gas to forcibly fill low-temperature, low-pressure SF6 liquid into cylinders, with short filling time and large filling capacity.
4. Uses a column-type level gauge, providing intuitive and accurate SF6 liquid level indication. The level has backlight indication for clear visibility.
5. The liquid storage container is equipped with a high-power SF6 vaporization electric heater. During use, temperature is automatically controlled to fully vaporize SF6 for external inflation.
6. The oil mist filtration system based on American Hankison principles ensures oil content meets standards. Compressor lubricating oil is guaranteed not to need replenishment within one year, and the oil level is ensured not to drop.
7. The molecular sieve drying system has reliable performance. Molecular sieve regeneration does not require disassembly, removal, or replacement, and is convenient to use. Only self-regeneration of the molecular sieve dryer is needed, and drying performance is restored to its original state.
8. All ball valves adopt American Swagelok working principles, with sealing elements having automatic compensation performance. They are practically applied in vacuum and pressure conditions, ensuring no leakage in both vacuum and pressure, making them dedicated ball valves for both vacuum and pressure use. (American Swagelok original ball valves can also be selected).
9. Customized phase sequence protection device, with voltage resistance up to 500V, greatly improving reliability.
10. Three-phase power supply, neutral wire is not necessary, and the whole unit is equipped with a leakage protector.
11. The flow chart is drawn on the panel for convenient and intuitive operation, all using ball valves with clear open and closed states.
12. Adopts air-cooled, mobile type, can be used without a water source.
13. High-quality casters for easy movement without damaging the floor.
14. Equipped with self-compensating valves to eliminate valve failure and gas leakage issues.
15. Check valves and one-way valves completely prevent oil return in case of power failure.
