The device is manufactured according to the DL/T662-1999 "SF6 Gas Charging and Recovery Device" standard. It consists of a vacuum pump, pointer vacuum gauge, regulating valve, gas pipeline, and necessary valves and instrument control components for maintaining SF6 circuit breakers. It has the following main functions:
Vacuuming and vacuum measurement for SF6 electrical appliances. 2. Inflating SF6 electrical appliances.
SF6 vacuuming and inflating device, SF6 vacuuming device, SF6 gas vacuuming device
Product Features

Power supply equipped with phase sequence automatic phase change system
High-precision thermocouple vacuum gauge, simple and practical
Advanced design, complete functions, reasonable structure, simple and clear operation
The control system of the device adopts the latest technology SF6 special valves
The equipment adopts a mobile structure, convenient for on-site use, easy to move, and does not damage the ground
The whole machine is small in size, light in weight, and low in noise
Technical Parameters
1. The ultimate vacuum of the device is less than 10Pa
2. The annual leakage rate of the device is less than 1%
3. The pressure of the inflation system is less than 0.8Mpa
4. Series models: Type 4 vacuum pump speed 4 liters/second (14.4m3/h)
8 type vacuum pump speed 8 liters/second (28.8m3/h)
15 type vacuum pump speed 15 liters/second (54m3/h)
30 type vacuum pump speed 30 liters/second (108m3/h)
70 type vacuum pump speed 70 liters/second (252m3/h) can choose Roots pump unit
150 type vacuum pump speed 150 liters/second (540m3/h) can choose Roots pump unit
Optional Configurations
1. Vacuum pump: using ZXZ series or German BUSCH, LEYBOLD
2. Vacuum gauge: using digital display vacuum gauge ZDR-I type or GD881 type
3. Valves use stainless steel bellows stop valve or imported ball valve, which can be connected to the gas cylinder and also connected to the inflation hose through a pressure reducing valve. Two types of connectors are available for selection.
4. Use DDC-JQ vacuum electromagnetic flap valve to connect with the vacuum pump. It can prevent the oil return phenomenon that may occur during the vacuuming process.
