Kufunika kwa madzi oyenda m’ng’anjo yazitsulo

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.

Palinso vuto lina pakugwiritsa ntchito kuzirala kwamadzi kotsekedwa komwe kuyenera kulipidwa. Makina ozizira amadzi azikhala ndi valavu yotulutsa utsi. Komabe, pakugwiritsa ntchito kwenikweni, makina ozizira amadzi ambiri osakhala ndi valavu yamoto amaikidwa. Ng’anjo ikatha ntchito kwa nthawi yayitali, mpweya umakhala wosavuta kulowa mu olekanitsa madzi. Chitsulo chosungunulira chitsulo chikayambiranso, gawo lina la mpweya limatsalira popatulira madzi ndi bokosi lamadzi lozizira lazinthuzo ndipo sizingatulutsidwe, zomwe zimapangitsa kulephera kwa chinthuchi. Kuzirala kwa madzi oyenda kumapangitsa kuti kutentha kuzikhala kwakukulu kwambiri kuti zisawononge zigawozo. Chifukwa chake, makina ozizira madzi opanda valavu wokhetsa madzi sagwiritsidwa ntchito kwa nthawi yayitali, ndipo amayambitsidwanso. Cholumikiza madzi pamalo okwera olekanitsa madzi ayenera kumasulidwa kuti akhetse mpweya wotsalira.
