This article roughly introduces the FM200 / hfc-227ea gas fire suppression system filling steps:
1.FM-200 Cylinder Cleaning
Before filling, the filling personnel should fix the cylinder first, and put it on the turning machine for high-temperature steam cleaning and drying, so that the cylinder group can be kept clean, and free of irrelevant matter and impurities.
The appearance of the cylinder group should have no obvious damage, and the cylinder group should not have the quality problems that will affect does not affect the filling. Make sure that the filling inlet is smooth and free of blockages.
2.FM-200 Gas Suppression System Cylinder Valve Assembly
Connect the siphon pipe to the container valve. There should be no sliding wire of the threaded connection, and the siphon connection should be firm and tight.
According to the production requirements, replace the corresponding cylinder valve bottle clamp structure and cylinder clamp structure.
3.FM-200 Cylinder Air Tightness Test
Connect and fix the air inlet of the assembled cylinder group to the air source for testing.
4.FM-200 Cylinder Group Vacuum Replacement
Connect the air inlet of the cylinder group that has completed the air tightness test with the vacuum test device, and turn on the vacuum pump
Fill the evacuated cylinder group with an appropriate amount of pure nitrogen
5.FM-200 Fire suppression Agent Filling
After being checked qualified, move the fire suppression agent cylinder group to the according area to be filled one by one
According to the weight of the FM-200 being filled, set up the alarm value on the electronic weighing scale, and weigh the empty cylinder to be filled after setting
After the filling of FM-200 reaches the required weight, that is, after the electronic weighing scale alarms, turn off the filling valve
Check out the thermometer diagram and the filling curve diagram of the filling place, and set the filling pressure according to the pressure corresponding to the environment temperature value
6.FM-200 Cylinder Group Tightness Test
Immerse the cylinder group in the water, keep it for 5 minutes, and check if there is leaking from the bottle group
During the test, the cylinder group should not have bubbles and leaking. After the qualified sealing, the cylinder group should be lifted out, put on the protective cap, and stored in the designated area.
7.Inspection of FM-200 After Refilling
After filling the FM-200, the professional person should inspect the cylinder group one by one. After being confirmed and qualified, the cylinders can be placed in the designated area.
8.FM-200 Filling Record
After done filling, the relevant person should record the information in the corresponding form including the filling date, cylinder number, room temperature, FM-200 production company, filling pressure, actual filling amount, filling starting and ending time, filling person, inspector, gas cylinder manufacturer, gas cylinder specifications, whether there is any abnormality, etc.
The fire extinguishing agent storage cylinder of the manifold type FM200 gas suppression system is usually placed in the special cylinder room and connected through the pipe network. When a fire occurs, the fire extinguishing agent will be conveyed from the cylinder to the protection area, and will be sprayed through the nozzle to extinguish the fire.
The inspection, test and maintenance of the gas fire suppression system is the guarantee to ensure the normal operation of the system when the fire occurs. Specific examples of 8 routine testing tasks.
