Oor gasvulling vir HFC-227ea-onderdrukkingstelsel

Nowadays many manufacturers lack maintenance of the HFC-227ea brandonderdrukkingstelsel for a long period, die gas druk is ernstig nie genoeg, the HFC-227ea gas leaks and evaporates, and the whole gas fire suppression system is invalid.

so, need to send HFC-227ea gas fire suppression equipment back to the manufacturer’s workshop to do inspection refilling, and testing.

Die volgende is 'n paar stappe en metings oor hoe om te hervul.

1. Gassilinder Cleaning

Before filling the personnel should fasten up the gas cylinder and place it on the rotary machine to do cleaning and drying, the cylinder should be cleaned without impurity, and the appearance of the gas cylinder should be without any damage and without any default, om te verseker van die vulling insette is onbelemmerd.

2. samestelling

• Put the siphon tube connected with the container valve, Gestruktureerde verbindings moet wees nie gly, siphon connection should be firm and not loose.
• According to the requirement of production, vervang die ooreenstemmende silinder clip struktuur.

3. Air Engheid Toets

Put an already assembled air inlet of gas cylinders connected with a gas source, fasten it, and do air tightness testing.

4. Silinder Vacuum Pomp en vervang

• After air tightness testing put the air inlet of the agent gas cylinder connected with the vacuum pumping test device, en begin die vakuumpomp.
• After vacuum pumping refill the cylinder with moderate pure nitrogen.

5. Blus agent Vulsel

• After the test and inspection of the cylinders, beweeg die agent gassilinders aan die gereed-vir-vul area.
• According to the predetermined gas filling weight, die opstel van die gewig klep by die elektroniese skaal, and put the empty gas cylinder on it to weigh.
• Na hervul die agent 'n sekere voorafbepaalde gewig, sluit die vul klep.
• Waarneming van die temperatuur by die vulling plek(werf) en vul kurwe, die opstel van die vulling druk volgens die omgewing temperatuur druk.

6. Lek digtheid toets

• Immersed the gas cylinder in water, stay for 5 minute, and observe the leakage of the cylinder.
• Tydens die toets, the gas cylinder should have no leakage and no bubbles, after the test hang out the cylinder fasten the protective cap, and store it at an appointed place.

7. Inspeksie Na Vulsel

na die invul, the specialist inspects the cylinders one by one, after inspection then puts them in an appointed place.

8. vulling Rekord

After filling it out, you should make a record, a record of the information:

• vul datum.
• Silinder nommer.
• Kamertemperatuur.
• Agent Produksie Vervaardiger.
• vuldruk.
• Werklike Vulsel Hoeveelheid.
• Vulling Valid Data.
• vulling Persoon.
• inspeksie Persoon.
• Gassilinder Produksie Vervaardiger.
• silinder spesifikasie.
• uitsondering inligting.

9. Finale Inspeksie

Uiteindelik, the final inspection again by a professional person one by one, and only after 100% confirmed the cylinder is good quality without default can move it to the pressurized gas cylinder storage area.
