The KDQH-33 SF6 gas recovery and filling device has comprehensive functions such as recovery, filling and discharging, purification, vacuuming, storage, and bottle filling. The series connection or switching of various functions is mainly achieved by operating the control box and ball valve concentrated on one side of the panel.

The system is equipped with reliable safety protection devices, and the high-pressure controller is installed at the exhaust port of the SF6 compressor. Once the exhaust pressure exceeds the limit value, it will automatically stop the operation of the compressor and restart it after the pressure drops; Once the safety valve is installed on the storage container and exceeds the pressure, it will automatically open to discharge gas and close automatically when the pressure drops.

Overall structure, the device adopts a hand push mobile type, which can adapt to normal indoor and outdoor environmental conditions for use. This device system is quite complex, consisting of a vacuum pump, SF6 compressor, refrigeration system, storage container, pipeline, various valves, instruments, and other accessories.

The electrical control box, operating valves, and monitoring instruments are all centralized on one side panel with process instructions, making them easy to use and clear.

*Transporting liquid SF6 between storage tanks and external gas cylinders

1. Recovery initial pressure ≤ 0.8MPa; Recovery final pressure ≤ 50KPa; Recovery time: For a 1 m3 SF6 gas volume with an initial pressure of 0.8 MPa, recover to a final pressure of 50 KPa, with a recovery time of less than 2.5 hours.
2. Inflate 1 m3 SF6 gas with an initial pressure of 133Pa to a volume of 0.8MPa, and the inflation time should be less than 0.8 hours.
3. Vacuum pumping: The maximum vacuum degree of the device is less than or equal to 10 Pa; The time required to evacuate a 1 m3 SF6 gas volume with an initial pressure of 0.1 MPa to 133 Pa is less than 1.0 hour.
