Attention to the operation of Teflon electric heater
Teflon electric heater is a new type of strong corrosion resistant electric heating tubular, which is used for heating various corrosive liquids. It has excellent anti-aging property and good bending performance, and adopts low surface load design. The joint adopts a fully enclosed anti-acid and alkali, non-heating section and overheating safety protection system. The integrity guarantees that the heater is not easy to burn, has a long service life, is fully sealed, does not corrode, does not leak electricity, has ground protection, and is safe and reliable. The applicable temperature is below 110 ° C.
The storage location of the electric heating element must be kept dry and appropriate insulation resistance. If the storage environment of the electric heating element is found to be too small, it can be restored by low voltage energization before use. The electric heating tubular should be properly fixed before use, and the wiring part should be placed outside the insulation layer, and avoid contact with corrosive and explosive media and water.
When used for heating liquids or metal solids, pay attention to the fact that the electric heating element must be completely placed in the object to be heated. It is not allowed to burn the electric heating tubular heater. If scale or carbon deposits on the outer metal tube shell after use, the electric heating element should be timely ** to avoid affecting the heat dissipation performance and service life of the electric heating tubular.
When used to heat easily melted metals or solid nitrate, paraffin, asphalt, etc., the heating substance must be melted first. At this time, the external voltage of the electric heating tube can be reduced, and the melting voltage can be restored to the rated voltage. In addition, safety measures must be fully considered when heating the heating pipe with substances that are liable to explode, such as nitrates.
When used for air heating, pay attention to the even arrangement of electric heating element. The advantage of doing so is to ensure that the electric heating tubular heater have sufficient and uniform heat dissipation space, and to ensure the air mobility as much as possible, and improve the heating efficiency of electric heating tubular element.
The inner gap is filled with magnesia. The magnesia at the outlet end of the electric heating tubular is easily contaminated by the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the electric heating element during operation to avoid leakage accidents caused by it.
