How to operate can make the electric heating tube use longer. On the one hand, it must be under the premise of ensuring the high quality of the electric heating tube. On the other hand, everyone may ignore it. Some professional knowledge and effective use of small methods can greatly extend the life of the electric heating tube. !
1. The terminal of the electric heating tube should be relatively fastened with two nuts when wiring. Do not use excessive force to avoid the loosening of the screw and damage the electric heating tube.
2. The heating pipe should be stored in a dry warehouse. If it is left for a long time, the surface is damp, and the insulation resistance is measured by using a megohmmeter. If it is less than 1 megohm / 500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying.
3. The heating part of the electric heating tube should be completely immersed in the heating medium to avoid the heat dissipation and the electric heating tube is damaged beyond the allowable heating temperature. In addition, the wiring lead-out part should be exposed outside the heater's insulation layer or heater so that this part should not be overheated and damaged.
4. Input power, the voltage should not exceed 10% of the rated voltage on the various electric heating tubes. If it is lower than the rated voltage, the heat generated by the heating tube will also decrease.
