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.
