The use of electric heating tubes is relatively simple, but there are more precautions that require us to read the instructions. Electric heating tubes can be seen in the field of heating products, and the amount of use is very large, so safe use and standard use are what we must understand.
We only use the electric heating tube correctly to play its role and extend the service life. When the power is input, the voltage cannot exceed 10% of the rated voltage marked on the various electric heating tubes. If you want the electric heating tube to fully heat up, the condition is to make the component reach the working conditions of the specified working state. To ensure the stability of the rated voltage. The voltage connected to the component specified in the design and marked on the component housing. The rated power refers to the component input power specified in the design and marked on the component housing.
The calculation formula of power density: length (cm) X width (cm) X 0.6~0.65 = power.
The use of electric heating tubes generally follow several principles:
1. Understand the environment in which the electric heating tube is used, whether it is medium conduction or infrared radiation.
2. Select the electric heating tube of the appropriate power, and pay attention to the power load problem under the premise of ensuring the effective use of temperature requirements.
3. Understand the temperature requirements of the electric heating tube, and choose an electric heating tube with a suitable power. In general, the higher the power, the faster heating and heating, and vice versa.
4. Dry heating of water-heated electric heating tubes is strictly prohibited, especially electric heating tubes for immersion use.
5. Special attention should be paid to the heat dissipation effect of the use environment for dry heating electric heating tubes, which are divided into static air and flowing air.
6. Fully understand the voltage of the electric heating tube. Under normal circumstances, the voltage of the electric heating tube is 220V and 380V.
7. Fully understand the wiring of electric heating tubes, usually star connection and delta connection. A single electric heating tube can be connected to 220V or 380V, and multiple electric heating tubes can be connected to 380V voltage.
8. The terminal of the stainless steel heating tube should be kept clean and dry, otherwise it will reduce the insulation performance and be short-circuited. If it is used in a chemically corrosive, flammable, explosive and other liquid or gas environment, the stainless steel electric heating tube should be connected to the wiring part Strictly protect with insulating and sealing devices to prevent accidents.
When using electric heating tubes, you can basically use them correctly as long as you follow the above principles. If you have any problems, please consult Xinhechang electric heating tube manufacturers for assistance.
