I. General Survey
filler for CO2 fire extinguisher is a special equipment for filling MT2-MT7 portable extinguishers with CO2 extinguishants automatically. It makes a comprehensive use of electronic, electric, and mechanical techniques and renders the whole filling processes safe, reliable, simple in operation, accurate in filling quantity and highly efficient.
II. Main Technical Parameters
1. Error Table for Filling Time and Quantity of the Filler
Specification Parameters Items | MT2 | MT3 | MT5 | MT7 |
Weight of extinguisher (kg) | 0 2 -0.15 | 0 3 -0.15 | 0 5 -0.2 | 0 7 -0.2 |
Filling time(s) | ≤50 | ≤60 | ≤60 | ≤90 |
2. Working Temperature and Pressure Parameters of the Thermostat of the Filler
A. Thermal uniform temperature is controlled in the range of 38°C–45°C with a pressure of 9-10Mpa, heater power of 6KW and voltage of 380V.
B. Cold uniform temperature is controlled in the range of –5°C—5°Cwith a pressure of ≤7Mpa and power source voltage of 220V.
The filling is based on the unique property of carbon dioxide. When the CO2 extingushant source is heated to some extent in the thermal thermostat, it is fed into the cold thermostat via pipes because of heating and increased pressure. When it is cooled, the pressure is reduced. The CO2 is filled into the container through the console by using the high pressure as the motive force to drive lower pressure.
