How to prevent safety hazards of explosion-proof electric heaters?
The safety hazards you do not want to see during the use of explosion-proof heaters include:. Let's take a look at the relevant steps for safety issues with explosion-proof heaters. Explosion proof heater, as the name suggests, is a device for heating materials. Due to its explosion-proof design, it is widely used in industrial production. How to prevent the safety of explosion-proof heaters.
1. It is strictly prohibited to place energized explosion-proof electric heating pipes on or near flammable materials.
2. The heating tube must be inserted correctly. It is strictly prohibited to directly insert the end of the wire into the socket. Otherwise, hot air may short-circuit and cause a fire.
3. The safe cutting of electric heating tube wires must meet the capacity requirements of the electric heating tube.
4. The device must be turned off when the user leaves
5. The resistance wire cannot be used after being repaired more than 3 times. Doing so will overload the pipeline and cause a fire.
Why is the electric heating tube very hot?
The electric heating tube is heated because there is a resistance wire in the electric heating tube. Once the resistance wire is energized, heat will be generated through the well insulated magnesium oxide powder and transferred to the electrically heated metal surface. Magnesium oxide powder has good insulation and thermal conductivity. In this case, the electric heating surface will rapidly rise, playing a heating role.
People often say that electric heating tubes can be heated because they have electric heating wires, which are generally divided into iron chromium aluminum wires and nickel chromium alloy wires. There are some differences in the prices and materials of these two types of electric heating wires.
Price: Iron, chromium, and aluminum are affordable and close to the price of the common people. The price level of nickel chromium alloy wire may be more expensive than that of iron chromium aluminum.
Material: 1. The temperature of iron, chromium, and aluminum used in the atmosphere is very high. The temperature of iron chromium aluminum electric heating wire 0cr27al7mo2z can reach 1400 ℃, while the temperature of nickel chromium wire cr20ni80z is only 1200 ℃.
2. Fe Cr Al alloy wire has a longer service life than Ni Cr alloy wire when used at the same temperature in the atmosphere.
3. Nickel chromium wire has good antioxidant properties, while iron chromium aluminum has weak antioxidant properties.
