Product Introduction
The KGQH-20 SF6 gas recovery unit consists of a vacuum pump, SF6 compressor, refrigeration system, storage vessel, piping, various valves, instruments and other accessories. The electric control box, operating valve and monitoring instrument are all concentrated on one side panel and have process instructions, so it is easy to use.
KGQH-20 SF6 gas recovery device has comprehensive functions such as recovery, charging and discharging, purification, vacuuming, storage, bottle filling, etc. The system is relatively complete. The series or switching of each function is mainly accomplished through the operation of the electric control box and the ball valve on one side of the panel.
The basic working principle of the KGQH-20 SF6 gas recovery device is to adopt freezing liquefaction method. During recovery, the suction and compressibility of the compressor are used to suction SF6 gas at a certain pressure in the SF6 electrical equipment into the compressor and compress it to a higher pressure. At the same time, the low evaporation temperature characteristic of R22 refrigerant is used to cool the SF6 gas at a higher temperature to the condensing temperature for liquefaction and storage. In this way, the SF6 compressor is continuously pumped to run in series until the final recovery pressure is reached.
When charging and discharging, the SF6 electrical equipment (or cylinder) and connecting pipeline are vacuum-vacuum-pumped by the vacuum pump of the device first, and then the SF6 in the storage container of the device is charged into the SF6 electrical equipment directly by using the pressure difference or the suction of the compressor to cause a certain pressure difference until the required working pressure is reached. At the same time, the characteristics of R22 refrigerant as described above are used to fill the liquefied SF6 directly into the cylinder.
The purification function is synchronously completed when the above recovery, charging and discharging functions are completed.

Product Characteristics
1. Three oil separators are arranged in the system, which are respectively installed at the outlet of the vacuum pump and two at the outlet of the compressor to effectively remove the oil carried by SF6 gas.
2, the system loop is provided with a filter dryer to ensure the purity of SF6 entering the storage container and effectively remove water. The filter has a heating regeneration device, which can be heated and regenerated under vacuum, so that the molecular sieve can be used repeatedly.
3, the system is equipped with a reliable safety protection device, high pressure pressure controller installed in the SF6 compressor exhaust port, once the exhaust pressure exceeds the limit value it will automatically stop the compressor work, and then restart the compressor after the pressure drops; The safety valve is installed on the storage container. Once the overpressure safety valve automatically opens to discharge gas, it automatically closes after the pressure drops.
4. Seven monitoring instruments and control instruments are also set up in the system, among which a vacuum gauge is installed in the device recovery inlet, and a DN8 valve is installed in front of the vacuum gauge, which can be opened when it is necessary to observe; Five pressure gauges, respectively installed on the recovery air inlet, SF6 compressor exhaust port, refrigerant compressor suction and exhaust port and storage container; A thermometer is installed on the refrigeration system and the SF6 liquid temperature is sensed by the temperature envelope.
5, the inlet of the vacuum pump in the system is equipped with an electromagnetic vacuum belt charging valve, and the vacuum pump is connected to the same power supply, when the pump stops working, the valve can automatically close the vacuum system, and the atmosphere is filled into the pump chamber through the pump inlet, so as to avoid the pump oil countercurrent pollution of the vacuum system.
6, the refrigeration system in the system by the high and low pressure controller to adjust the inlet and outlet pressure of the refrigeration compressor. Once the refrigerant compressor exceeds the limit range, the compressor automatically cuts off the work. When the low pressure is disconnected, wait for the pressure to rise, or when the high pressure is disconnected, wait for the pressure to fall, and then restart the compressor.
7, the overall structure, the device adopts hand-propelled mobile, can adapt to indoor and outdoor normal environmental conditions.
8. The system of this device is more complex, consisting of vacuum pump, SF6 compressor, freezing system, storage container, pipeline, various valves, instruments and other accessories.
9, the electric control box, operating valves and monitoring instruments are all concentrated on one side panel and have process instructions, so it is easy to use.
