What are the main uses of electric heating tubes?

Electric heating tubes have a wide range of applications, mainly including the following:

1. Used for drying wood, paper, printing and dyeing, paint residue, etc.

2. Melting heating of saltpeter and other salt substances.

3. Melt low melting point alloys, such as lead melting furnaces, tin melting furnaces, etc.

4. Building heating.

5. Heat flowing air and stationary air.

6. Infrared radiation heating device.

7. Low temperature electric furnaces, such as industrial electric furnaces with air circulation, electric furnace boxes, etc.

8. Heating devices in oil, water, and other chemical liquids, as well as electroplating bath fluids.

9. Seawater electric distillation device.

10. Heating device for alkali and acid.

In the food industry, it is used to bake various breads, biscuits, and pastries, and is used as an electric heating device in a water tunnel.

12. In plastic product processing and extrusion equipment and rubber product molding and vulcanization equipment.

13. In medical and health disinfection equipment, such as sterilizers, disinfectors, etc.

14. Heating equipment for vacuum impregnation of motors, drying equipment for enameled wires, etc.

15. Various household electric appliances in daily life, such as electric stoves, ovens, rice cookers, fryers, water heaters, electric irons, and other products.

The voltage specifications of the electric heating tube must be confirmed before purchase. The confirmation of this step is equivalent to the fixed resistance value on the equipment. The higher the voltage, the greater the power. If selected incorrectly, it is particularly easy to cause the voltage to exceed the load of the electric heating tube, leading to the problem of the power generation resistor wire being blown, or even the electric heating tube being broken. Conventional voltage specifications: 24V, 36V, 48V, 110V, 220V, 380V, usually we refer to the rated voltage.

Rated voltage of electric heating tube:

The rated voltage of the electric heating tube refers to the voltage specified and marked on the outer shell of the electric heating tube during redesign, which is connected to the electric heating tube. Or to put it another way, the rated voltage is the voltage given when the customer requests us to process and produce. Generally, there are 24V, 48V, 110V, 220V, 380V, and so on.

Working voltage of electric heating tube:

(1) Multiple series power supplies, for a group of electric heating tubes or tubes connected in series to the power supply, the working voltage of the electric heating tubes refers to the voltage specified in the design when connected to this group of electric heating tubes.

(2) For a single connected power supply, for a single connected electric heating tube, the working voltage of the electric heating tube refers to the voltage specified in the design to be connected to the component, that is, the rated voltage.

Note: This involves the issue of whether multiple electric heating tubes are connected in series or in parallel. So when judging the voltage, if multiple electric heating tubes need to be connected, it is necessary to consider whether they are connected in series or in parallel to determine the voltage of a single electric heating tube.

The impact of voltage on power:

When the power of the electric heating tube is determined, if the voltage is less than the designed voltage, it will lead to a decrease in power and a decrease in heating efficiency; If the voltage is greater than the design voltage, it will lead to an increase in power, a high load, and the possibility of internal heating wire melting or even breakdown of the heating tube.
