How to reduce the risk of using cast copper heaters
Improper operation of the heater can pose certain safety hazards. Below, the electric heating sink will briefly share with you how to reduce the risk of using cast copper heaters.
Firstly, regarding the allowable working conditions for the cast copper heater, including a relative dryness greater than 95%. No explosive corrosive gas; The voltage should not exceed 1.1 times the rated value, and it should also be reliably grounded; The insulation resistance is ≥ 1MQ, providing a good foundation for the safe use of the heater. Secondly, the casting copper heater should be well positioned for flow, and the effective heating area must be partially immersed in liquid or metal, and it is strictly prohibited to burn empty; Once scale or carbon deposits are found in the pipe body, they should be promptly removed and reused to avoid affecting heat dissipation and extending service life.
When heating fusible metals or solid nitrates, alkali leaching, paraffin, etc., the operating voltage should be lowered first, and only after the medium melts can it be lowered to the rated voltage. When heating the atmosphere, the components should be evenly listed and crossed to provide excellent heat dissipation conditions for the components, so that the flowing atmosphere can be fully heated. The wiring part of the cast copper heater should be placed in an insulation layer to avoid contact with corrosive and explosive media moisture; The lead wire should be able to withstand the temperature and heating load of the wiring section in a durable manner; When tightening the wiring screws, excessive force should be avoided.
