2. Working temperature and pressure parameters of the filling machine thermostatic device
A. The thermal constant temperature control range is 38°-45° and the pressure is 9-10Mpa
Heater power 6KW voltage 380V
B. The cold constant temperature control range is -5°--5° pressure ≤7Mpa
Voltage 220V
3. Working principle and equipment arrangement
When the fire extinguishing agent source heats up to a certain temperature in the hot thermostatic device, the pressure increases due to the heat, and is sent into the cold thermostatic device through the pipeline.
After encountering cold, the pressure decreases, and under the action of high pressure driving and low pressure, it is poured into the container to be filled through the control cabinet.
