Now solvent supplier heptafluoropropane gas fire extinguishing equipment is widely used in: electronic computer room, library, archives, valuables warehouse, power station (transformer room), telecommunication center, data center, clean workshop and other key parts as fire protection equipment. But do you know the chemical filling steps of heptafluoropropane gas fire extinguishing equipment? The steps for filling the heptafluoropropane gas fire extinguishing equipment are as follows:
1. Cylinder cleaning
Before filling, the filling personnel should fix the steel cylinder and place it on the turning machine for high-temperature steam cleaning and drying. The bottle group is clean, free of foreign matter and impurities, the appearance of the bottle group has no obvious damage, and there is no quality problem that affects the filling of the medicine. , to ensure the filling inlet is smooth and free of blockages.
Second, the bottle valve assembly
1. Connect the siphon tube to the container valve. The threaded connection should be free of slippage, and the siphon tube connection should be firm and free of looseness.
2. According to production requirements, replace the corresponding container valve bottle clamping mechanism and cylinder clamping structure.
3. Air tightness test
Connect the air inlet of the assembled bottle group to the air source and fix it for inspection.
Fourth, the bottle group vacuum replacement
1. Connect the air inlet of the bottle group that has completed the air tightness test with the vacuum test device, and start the vacuum pump;
2. Fill the evacuated bottle group with an appropriate amount of pure nitrogen.
Five, fire extinguishing agent filling
1. After the bottle group is qualified, move the fire extinguishing agent bottle group to the area to be filled one by one;
2. According to the weight of the medicine to be filled, set the alarm value on the electronic platform scale, and put the empty bottle to be filled after setting;
3. After heptafluoropropane is filled to the required weight (alarm), close the filling valve;
4. Observe the temperature gauge of the filling site and the filling curve, and set the filling pressure according to the pressure corresponding to the ambient temperature value;
6. Bottle sealing test
1. Immerse the bottle group in water and keep it for 5 minutes to observe the leakage of the bottle group;
2. During the test, the bottle group should be free of bubble leakage. After the sealing is qualified, the bottle group should be lifted out, put on the protective cap, and stored in the designated area.
7. Inspection after reinstallation
After the filling is completed, the bottle group will be inspected one by one by a special person, and the designated area can be placed only after the inspection is correct.
8. Filling record
After the filling is completed, the "limin chemical drug filling record form" should record: filling date, bottle number, room temperature, drug production unit, filling pressure, actual filling amount, filling start and end time, filling person, Inspectors, cylinder manufacturers, cylinder specifications, whether there is any abnormality, etc.
9. After the filling is completed, it must be inspected by a special person one by one, and only after passing the test can it be transported to the storage area of the pressurized bottle group.
