SF6 Gas Vacuum Pumping and Filling Device Direct Sales PriceProduct Features:
● Adopts the design principle of freezing and liquefaction, which reduces the working pressure of the system and greatly improves the recovery efficiency.
● The refrigeration compressor can be optionally equipped with an original French imported fully hermetic refrigeration compressor. It can also be upgraded for free to a semi-hermetic refrigeration compressor produced by a wholly American-owned enterprise, Emerson-Copeland (performance far exceeds any original imported fully hermetic compressor of the same cooling capacity).
● The SF6 compressor is a semi-hermetic compressor produced by a wholly American-owned enterprise (Emerson-Copeland brand), applied to halogen gases such as SF6, with fluorine resistance characteristics, ensuring no leakage.
● The vacuum pump can be optionally equipped with a Japanese Ulvac two-stage rotary vane vacuum pump or a German original Busch, German wholly-owned Leybold, etc.
● Dual container system, SF6 can be liquefied and can be filled into cylinders, with a filling amount not less than 50kg. The single container recovery device has a cylinder filling amount not less than 30kg.
● The dual container system has a unique SF6 vaporization method, using high-temperature high-pressure SF6 gas to force low-temperature low-pressure SF6 liquid into the cylinder, with short time and large filling amount.
● A column type liquid level gauge can be used, with intuitive and accurate SF6 liquid level indication. The liquid level has backlight indication, clear and unambiguous.
● 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 inflation.
● Excellent imported (American) oil mist filtration system ensures oil content meets standards. Compressor lubricating oil ensures no need to add within one year, and the oil level is guaranteed not to drop.
● The molecular sieve drying system has reliable performance. The molecular sieve does not need to be disassembled, dismantled, or replaced during regeneration, and is easy to use. Only a self-regeneration operation of the molecular sieve dryer is required, and the drying performance can be restored to its original state.
● All ball valves adopt the American swagelok working principle, and the sealing elements have 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).
● Customized phase sequence protection device, with a withstand voltage of up to 500V, greatly improving reliability.
● Three-phase five-wire power supply, safer and more reliable.
● The flow chart can be drawn on the panel, making operation convenient and intuitive. All ball valves are used, and the open and closed states are clear.
● Adopts air cooling and mobile type, can be used without water source.
● The vacuum gauge is a digital display Pirani vacuum gauge.
● High-quality casters, easy to move, do not damage the ground.
Product Overview:
It has a vacuum pumping system, compression system, purification system, storage system, and condensation system. It is used in manufacturing plants of SF6 gas insulated electrical equipment, and in departments of operation, research, etc., to evacuate various electrical equipment, fill SF6 gas into electrical equipment, and recover SF6 gas from electrical equipment in use or under test, while purifying and compressing it for storage in storage tanks. The recovery device is suitable for SF6 electrical appliances of various voltage levels and GIS combined electrical appliances, etc.
Referring to the power industry standard DL/T 662-1999 "Technical Conditions for Sulfur Hexafluoride Gas Recovery Device" and the former Ministry of Machinery and Electronics JB/DQ2588-90 "SF6 Filling and Recovery Device" standard, and referencing the advantages of the world-renowned brand German DILO products, this SF6 gas recovery and filling device is developed, which is more suitable for China's SF6 high-voltage switchgear industry.
