Pentinge banyu sirkulasi ing tungku peleburan logam

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.

Ana masalah liyane babagan panggunaan pendinginan banyu tertutup sing kudu digatekake. Sistem pendingin banyu kudu dilengkapi katup knalpot. Nanging, ing panggunaan nyata, umume sistem pendingin banyu tanpa katup knalpot dipasang. Nalika tungku ora suwe digunakake, gas gampang dilebokake menyang pemisah banyu. Nalika tungku peleburan logam diwiwiti maneh, bagean saka gas bakal tetep ana ing pamisah banyu lan kothak banyu sing adhem komponen kasebut lan ora bisa dibuwang, nyebabake kegagalan komponen iki. Pendinginan banyu sing sirkulasi nyebabake suhu dadi dhuwur banget kanggo ngobong komponen kasebut. Mula, sistem pendingin banyu tanpa katup pembuangan ora digunakake suwene, banjur bisa diaktifake maneh. Klem banyu ing pucuk pamisah banyu paling dhuwur kudu dilonggarkan kanggo ngilangi gas sing isih ana.
