Abstract

The invention relates to the technical field of gas charging, particularly to charging equipment for heptafluoropropane firefighting gas and technology thereof. Compared with the prior art, according to the invention, a diaphragm compressor with the power of 5.5kW is adopted, and electric energy is used as the driving force so as to reduce energy consumption; and the structure of the charging equipment is changed so that the charging equipment for heptafluoropropane firefighting gas can simultaneously charge a plurality of firefighting gas cylinders and can be massively produced.

Description

technical field [0001] The invention relates to the technical field of gas filling, in particular to a filling equipment and process for heptafluoropropane fire-fighting gas. Background technique [0002] see figure 1 The structure of the most common heptafluoropropane fire-fighting gas filling equipment is as follows: the output end of the air compressor 1 and the gas-driven liquid pump of the recovery circulation system 5 are sequentially connected to the refrigerator 2, the filter group 3 and the pressure-stabilized gas storage tank 4. The output end of the raw material barrel 6 is connected to the raw material input end of the recycling system 5, and the output end of the recycling system 5 is connected to the fire-fighting gas cylinder 7. The bottom of the fire-fighting gas cylinder 7 is provided with an electronic scale 9, and the fire-fighting gas cylinder 7 The top is connected with the pressurized nitrogen cylinder 8. [0003] In the existing heptafluoropropane fi...
