Explosion-proof immersion heater is an internationally popular high-quality long-life electric heating device, which is energy-efficient and is used for heating, holding and heating liquid and gaseous medium. Generally used in dangerous places where there is a possibility of explosion. Due to the presence of various inflammable and explosive oils, gases, dusts, etc. in the surrounding environment, once exposed to the electric spark, it will cause an explosion. Therefore, in this case, it is necessary to use explosion-proof heater heating. Device. The explosion-proof rating of the heater varies from case to case, depending on the situation.
The electric heating tubular should be positioned and fixed, and the effective heating zone must be completely immersed in liquid or metal solids. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life. The magnesium oxide powder at the outlet end of the electric heating pipe is protected from the infiltration of pollutants and moisture in the place of use to prevent the occurrence of electric leakage accidents. Safety measures should be taken when heating nitrates to prevent explosions. Moreover, the electric heating pipe should use the products produced by the regular manufacturers that meet the national standards, and beware of dangers.
