What should be paid attention to in the use of bearing induction in tubular heaters?
Knowledge of safe use of electric tubular heaters in cold weather
1. Do not place the heater directly around the power socket, and do not touch the heating elements inside the heater with your hands to prevent danger;
2. The temperature of the air duct of the industrial heater and the air sent can be very high, so be careful to prevent burns;
3. The address of the industrial fan heater is far away from flammable and explosive hazardous materials and gases to prevent danger;
4. It is not allowed to use the fan heater in any watery or humid place. If water gets on the working fan heater, it may cause a short circuit or leakage of the machine;
5. In case of emergency, you can directly press the emergency brake to shut down, and you can reset and resume work after safety is guaranteed;
6. The address of industrial fan heater is well ventilated, and should not be used in a sealed box;
7. Before using the heater, you must check whether the voltage and current meet the requirements of the machine. You must use a grounded socket and the wire must meet the request.
So what should be paid attention to in the use of bearing induction in electric heaters?
The production data that affects its loss are mainly the core data and the winding data: the core data is also the silicon steel sheet. The silicon in the steel sheet can reduce its own conductive function, add resistivity and then reduce the loss of eddy current so it is heated The quality of the device has a great relationship with the quality of the silicon steel sheet. The quality of silicon steel sheet is usually indicated by magnetic flux density. Winding materials are usually made of copper wire, and its loss is indicated by copper loss. For proper bearing heaters with small transformers, copper loss is greater than iron loss, so the process request for copper wire materials and winding materials is very high. The best choice is high-strength polyester enameled wire, which has a relatively small resistance value, good electrical conductivity, and an insulating lacquer layer with sufficient heat resistance. Therefore, the function of the heater wound with high-strength polyester enameled wire is superior.
Some electric tubular heaters must be customized according to user requirements
1. Working temperature
2. Detailed structural dimensions
3. Heating power
Instructions for use:
1) The operating voltage must not exceed 10% of the rated value;
2) The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded;
3) The cast aluminum heater should be placed in a dry place. If the insulation resistance is less than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours to return to normal
