Girîngiya gera avê di firna helandina metal de

In most metal smelting furnaces, the furnace body and the power cabinet have two independent water systems, an internal circulation system, an external circulation system, internal closed-circuit deionized water, and include a water-to-water heat exchanger, rectification Silicon, reactors, filter capacitors, inverter silicon, and resonance capacitors are all connected to this system. Since the internal water system circulates in the DC high voltage, the internal cooling water will generate electric ions under the action of the pipeline DC high voltage. After a period of time, the concentration of electric ions will gradually increase. When the concentration of electric ions exceeds the required value, the high DC voltage will corrode the copper joints through the cooling water with high concentration of ions, resulting in the situation seen in the photo below. If the water connector corrodes and breaks during use of the power supply, the pressurized cooling water will spray out, causing major equipment accidents, and the cooling water with high concentration of electric ions will reduce the insulation of the system, which is more likely to cause damage to the thyristor Therefore, the conductivity of the cooling water should be checked regularly, and it must be less than 10us/cm. If the conductivity is greater than 100us/cm, replace the circulating cooling water in all power cabinets, and it is recommended to replace it every six months.

Di karanîna sarbûna ava girtî de pirsgirêkek din heye ku divê meriv bala xwe bide ser. Pêdivî ye ku pergala sarbûna avê bi valahiyek derxistî were saz kirin. Lêbelê, di karanîna rastîn de, piraniya pergalên sarbûna avê bêyî valahiyek xilasbûnê têne saz kirin. Dema ku firne ji bo demek dirêj ji kar dûr e, gaz bi hêsanî têkeve nav veqetînerê avê. Dema ku sobeya helandina metal ji nû ve were dest pê kirin, dê beşek gazê di veqetînerê avê û qutiya ava sarbûnê ya pêkhateyan de bimîne û neyê derxistin, di encamê de têkçûna vê hêmanê. Sarbûna ava çerx dibe sedem ku germahî pir zêde be ku hêmanan bişewitîne. Ji ber vê yekê, pergala sarbûna avê bêyî valahiyek xilasbûnê demek dirêj nayê bikar anîn, û ew dîsa tê aktîf kirin. Çêlka avê li cihê herî bilind a veqetînerê avê divê were şil kirin da ku gaza mayî biherike.
