Electric heating tube is an electric heating element used to convert electrical energy into thermal energy. It can be used alone or as an electric heating element in various electric heating equipment. When using the electric heating tube alone, attention should be paid to its allowable working conditions and some normal operation precautions to ensure the safety and heating effect of the electric heating tube. Today, let me make a supplement again, hoping it will be helpful to everyone.
Precautions for operating electric heating tubes:
1. The storage location of electric heating tubes must be kept dry and have appropriate insulation resistance. If it is found that the insulation resistance of the storage environment of electric heating tubes is too low during use, they can be restored with low voltage power before use. Electric heating tubes should be properly fixed before use, and the wiring should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and water.
2. The gap inside the electric heating tube is filled with magnesium oxide sand. The magnesium oxide sand at the outlet of the electric heating tube is prone to contamination due to the infiltration of impurities and moisture. Therefore, it is necessary to pay attention to the condition of the outlet of the electric heating tube during operation to avoid leakage accidents.
3. When using electric heating tubes for air heating, attention should be paid to the uniform arrangement of the electric heating tubes. The advantage of doing so is to ensure that the electric heating tubes have sufficient and uniform heat dissipation space, and to ensure the fluidity of the air as much as possible, improving the heating efficiency of the electric heating tubes.
4. When using electric heating tubes for heating liquids or metal solids, attention should be paid to placing the electric heating tubes completely inside the heated object, and it is not allowed to have empty burning of the electric heating tubes. If there is scale or carbon on the outer metal shell of the electric heating tube after use, it should be promptly removed to avoid affecting the heat dissipation performance and service life of the electric heating tube.
5. When an electric heating tube is used to heat easily melted metals or solid substances such as nitrates, paraffin, asphalt, etc., the heating substance needs to be melted first. At this time, the external voltage of the electric heating tube can be reduced, and it can be restored to the rated voltage after melting is completed. In addition, when heating substances such as nitrates with electric heating tubes that are prone to explosion accidents, safety measures should be fully considered.
