Attention to the operation of Teflon heater
Teflon electric heater is a new type of strong corrosion resistant electric heating element, which is used for heating various corrosive liquids. It has excellent aging resistance 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. If scale or carbon deposits on the outer metal tube shell after use, the electric heating tubular heater should be timely ** to avoid affecting the heat dissipation performance and service life of the electric heating element.
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 uniform arrangement of the electric heating tubular element. The advantage of doing so is to ensure that the electric heatingelements have sufficient and uniform heat dissipation space, and to ensure the air mobility as much as possible, and improve the heating efficiency of the tubular heater.
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 tubular during operation to avoid leakage accidents caused by it.
1) The Teflon electric heater is made of high-grade stainless steel (sus316 or sus304) electric heating tube core and made of Teflon tube (PTFE). It has strong corrosion resistance and is suitable for heating various corrosive liquids.
2) The heater uses a low surface power design (1.5w / c㎡) to ensure the service life of the product.
3) The installation position of the electric heater should pay attention to prevent the solids in the solution from depositing on the surface of the electric heater, or the liquid is too thick and the liquid level is too low, which will burn out the iron fluoride (PTFE) due to poor surface heat dissipation.
4) The size of the electric heater cannot be changed casually and the surface area is changed, otherwise the surface power of the electric heater will be too large and the service life of the electric heater will be affected.
5) All electric heaters can be equipped with over-temperature protection or PT-100 temperature sensor to ensure product life and safety.
6) The joint adopts fully enclosed anti-acid and alkali, non-heating section and overheating safety protection system are completely made according to customer needs.
