After installation, the height of the machine is 220cm, and the top is made of aluminum infrared reflection cover. Combustion. The furnace head fire net adopts imported high-density high-quality stainless steel alloy material, which is corrosion-resistant and fire-resistant, which can ensure the service life and effect of the product to the maximum extent. The combustion furnace head adopts the most advanced gas combustion technology in Europe, and the air ratio of the gas reaches the optimal value to ensure that each gas can be fully burned to produce the maximum heat and the minimum exhaust emiss.
Umbrella heaters usually have dump protection, flameout protection and anoxic protection.
一、 Flameout protection:
No matter the heater for any reason after flameout, the heat should be needle (that is, thermocouple) will stop to produce current (the current in the protection device has thermal inductance without external power supply), no current state solenoid valve automatically open and close the gas supply pipeline, so that the heater automatically cut off. To reignite, reset the control switch of the heater and restart the operation.
When the heater is working normally, if the collision produces vibration or dumping, the built-in dumping protection switch will immediately react to cut off the power supply circuit of the solenoid valve, and the solenoid valve will open and close the gas supply pipeline, so that the heater will automatically expire and flutter. To reignite, reset the control switch of the heater and restart the operation.
三、 hypoxia protection:
Oxygen in the air did not fall to affect the normal breathing of the human body before the flame from the thermal should needle, thermal should needle (that is, thermocouple) will stop producing current, no current state solenoid valve automatically open closed gas supply pipeline, so that the heater automatically expire. Reignite the heater control switch first
Reset and reoperate.
The three kinds of protection are finally realized by the solenoid valve, such as any kind of protection failure, the heater will not be able to open the normal work, so there is no heater can also be used, the failure of the protection device. If the heater is lit and released, it will automatically go out. This fault is generally caused by the failure of the protection device. The solution is to replace the heat-sensing needle or solenoid valve.
