Precautions for Using Heating Preheating Rods - Yangzhou Darui
Darui Electric recommends for youMany netizens have reported online thatflange electric heating tubesoften experience electric leakage or shortened service life when used alone. We remind customers that such problems may be due to choosing unqualified products on one hand, and on the other hand, the following points should be paid more attention to during use:
1. When flange electric heating tubes are used to heat easily melting metals or solid substances such as nitrate, paraffin, asphalt, etc., the substance to be heated should be melted first. At this time, the external voltage of the flange electric heating tube can be reduced, and after melting is completed, restore to the rated voltage. In addition, when heating substances like nitrate that are prone to explosion accidents, safety measures should be fully considered.
2. The storage location of flange electric heating tubes must be kept dry and have appropriate insulation resistance. If it is found that the insulation resistance of the storage environment is too low during use, it can be restored by applying low voltage power before use. Flange electric heating tubes should be properly fixed before use, and the wiring part should be placed outside the insulation layer, avoiding contact with corrosive, explosive media and water.
3. When flange electric heating tubes are used for air heating, attention should be paid to the uniform arrangement of the tubes. This ensures sufficient and uniform heat dissipation space, and as much as possible ensures air fluidity, improving the heating efficiency of the flange electric heating tubes.
4. The internal gap of flange electric heating tubes is filled with magnesium oxide sand. The magnesium oxide sand at the outlet end of the tube is easily contaminated by impurities and moisture, so attention should be paid to the state of the outlet end during operation to avoid electric leakage accidents caused by this.
