SF6Gas 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-RPSF6SeriesSF6 Gas Recovery and Inflation Device. Key main components are 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 high-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 liquid 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, automatic temperature control ensures sufficient vaporization of SF6 for external inflation.
6. The oil mist filtration system based on American Hankison principles ensures oil content meets standards. Compressor lubricating oil does not need to be added 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 easy to use. Only self-regeneration of the molecular sieve dryer is needed, and the drying performance can be restored to its original state.
8. All ball valves adopt the American Swagelok working principle, with sealing elements having automatic compensation performance. They are practically applied in vacuum and pressure conditions, ensuring no leakage under both vacuum and pressure, making them special 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 intuitive and convenient operation. All ball valves are used, 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 completely eliminate valve leakage problems.
15. Check valves and one-way valves completely prevent oil return in case of power failure.
