SF6 Gas Liquid Full-Function Recovery Device
I. Device Introduction
Our company, based on the electric power industry standard DL/T 662-1999 "Technical Conditions for SF6 Gas Recovery Devices" and the former Ministry of Machinery and Electronics Industry standard JB/DQ2588-90 "SF6 Gas Filling and Recovery Devices", has independently developed the YDL-RPSF6 series SF6 gas recovery and filling device. Key main components are imported products. This device possesses the essential functions of general SF6 gas recovery and filling devices, such as vacuuming, filling, recovery, and storage.
II. Device Features
1. Adopts the design principle of freezing 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 has 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 liquid level gauge, providing intuitive and accurate SF6 liquid level indication. The liquid level has backlight indication, clear and unambiguous.
5. The liquid storage container is built with a high-power SF6 vaporization electric heater. During use, automatic temperature control is performed to fully vaporize SF6 for external filling.
6. The oil mist filtration system based on the American Hankison principle 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 decrease.
7. The molecular sieve drying system has reliable performance. Molecular sieve regeneration does not require disassembly, dismantling, or replacement, and is convenient to use. Only self-regeneration operation 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 to vacuum and pressure conditions, ensuring no leakage under both vacuum and pressure, and are 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 machine is equipped with a leakage protector.
11. The flow chart is drawn on the panel, making operation convenient and intuitive. All ball valves are used, with clear open and close states.
12. Adopts air-cooled, mobile type, can be used without water source.
13. High-quality casters for easy movement without damaging the floor.
14. Equipped with self-compensating valves to eliminate valve leakage issues
15. Check valves and one-way valves completely prevent oil return in case of power failure
