s a common electric heating element, electric heating tube is mainly used to convert electric energy into thermal energy. It can be applied to various electric heating devices or can be used alone. According to reports, electric heating pipes often leak when they are used alone, or the service life is shortened. Ruigao reminds customers that such problems may be caused by the selection of unqualified products (recommended here for you), and on the other hand, Ruigao reminds you to pay more attention to the following points:
1. When the electric heating tube is used for air heating, pay attention to the uniform arrangement of the electric heating tubes. The advantage of this is to ensure that the electric heating tube has a relatively sufficient and uniform heat dissipation space, and as much as possible to ensure the fluidity of the air and improve the heating of the electric heating tube. effectiveness.
2. When the electric heating tube is used to heat the easily melted metal or solid nitrate, paraffin, asphalt and other materials, the heating material should be melted first. At this time, the external voltage of the electric heating tube can be reduced, and then the rated voltage is restored when the melting is completed. In addition, when the electric heating pipe heats a substance that is prone to explosion accidents such as nitrate, it is necessary to fully consider safety measures.
3. When the electric heating tube is used for heating liquid or metal solids, it must be noted that the electric heating tube must be completely placed in the object to be heated, and the electric heating tube is not allowed to be burnt. If the outer metal casing is covered with scale or carbon after the electric heating tube is used, it should be cleaned in time to avoid affecting the heat dissipation performance and service life of the electric heating tube.
4. The gap inside the electric heating tube is filled with magnesia oxide. The magnesia sand at the outlet end of the electric heating tube is easily contaminated by the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the electric heating tube during operation to avoid the leakage caused by the electric heating tube. accident.
5. The storage position of the electric heating pipe must be kept dry and proper insulation resistance. If it is found that the insulation resistance of the storage environment of the electric heating pipe is too small, it can be restored after low voltage power supply. The electric heating tube should be properly fixed before use. The part of the wiring should be placed outside the insulation layer and avoid contact with corrosive, explosive media and water.
