In the heater industry, there are many types according to different materials, such as cast copper heaters, cast aluminum electric heaters, ceramic heaters, etc. Among them, cast copper heaters are used more and more widely. However, it should be known that there are certain safety hazards in the use of heaters made of this material, so their application conditions must be strictly regulated.
The first is about the allowable working conditions of the cast copper heater, including the relative dryness of the atmosphere is greater than 95%, no explosive corrosive gas; the voltage does not exceed 1.1 times the rated value, and at the same time, it must be reliably grounded; the insulation resistance is greater than or equal to 1MΩ, Provide a good foundation for the safe use of heaters.
Secondly, the cast copper heater should be well positioned and flowed. The effective heating area must be partially immersed in liquid or metal solids, and empty burning is strictly prohibited; once scale or carbon formation is found in the pipe body, it should be removed and reused in time to avoid affecting Dissipate heat and extend service life.
When it is heating fusible metals or solid nitrates, alkalis, lime, paraffin, etc., the operating voltage should be reduced first, and the rated voltage should be reduced after the medium is melted. When heating the atmosphere, the elements should be crossed and evenly arranged, so that the elements have excellent heat dissipation conditions, so that the flowing atmosphere can be fully heated.
The wiring part of the cast copper heater should be placed in the insulation layer to avoid contact with corrosive, explosive media and moisture; the lead wire should be able to withstand the temperature and heating load of the wiring part; excessive force should be avoided when tightening the wiring screws, etc.
