How to prolong the life of electric heating element

According to our work experience, as long as the use of appropriate heating element tube, life can be roughly more than 1 year or even longer, the life of the time with the working environment of the electric tube is closely linked.

Electric tube is specialized electrical energy into electrical energy components, because of its cheap, easy to use, non-polluting, are widely used in a variety of heating applications.Ck0TFP1UkAAm89X.jpg

Electric heating element tube life is very long, the general design life of more than 6000 hours, the equivalent of four heating season, if the usual attention to good maintenance work, but also further extend its service life.

1. Electric tube terminals, the application of two nuts in the wiring is relatively tight, do not force too much to avoid loosening of the lead screw leads to damage the electric tube.

2. Selection of electric heating tube should pay special attention to the heating medium, the shell material should be no effect of electric heating.

3. The use of electric heating pipe, if the surface accumulation of thick pipe scale, grease, should be regularly removed, otherwise it will reduce the heat pipe heat pipe surface heat load caused by damage to the allowable rating.

4. Heating part of the heating tube should be fully immersed in the heating medium, to prevent heat dissipation and not allow more than allow the heating temperature of the electric tube damage. Also, the wiring lead-out part should be exposed outside the insulation layer of the heater or the heater, so that this part should not be overheated and be damaged.

5, the electric tube terminals should be kept clean, dry, and vice versa will reduce the insulation performance was short-circuit breakdown, if the application of chemical corrosion, flammable, explosive and other liquid or gas environment, the electric pipe wiring part of the insulation Seal to strict protection to prevent accidents.

6. Heating tube should be stored in a dry warehouse, if the long-term placement, surface moisture, measured in the use of megger insulation resistance. If less than 1 megohm / 500 volts, it should be placed in a 200-degree heating tube drying oven.

7. Electric heating pipe input power, voltage should not exceed a variety of electric heating pipe marked on the rated voltage of 10%, such as applied to less than the rated voltage, electric heat generated by the tube will decline.

8. Heating part of the heating tube should be fully immersed in the heating medium to avoid heat dissipation and not allow more than allow the heating temperature of the electric tube damage. Also, the wiring lead-out part should be exposed outside the insulation layer of the heater or the heater, so that this part should not be overheated and be damaged.

9 heating some viscose and other substances, such as sodium nitrate, stearic acid, paraffin, etc., should be heated to reduce the power supply voltage to reduce the heat of the electric tube until all the molten into a liquid, and then rose to rated Voltage for heating.

In fact, the length of the heating tube, really depends on the beginning of the electric tube design, electric tube internal material selection and external material selection. Find out the working environment of the electric tube, the correct choice of electric tube of various materials, the real life of the electric tube is essential.
