Ukubaluleka kokujikeleza kwamanzi esithandweni sokuncibilikisa insimbi

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.

Kunenye inkinga ekusetshenzisweni kokupholisa amanzi okuvaliwe okufanele kunakwe. Isistimu yokupholisa amanzi kufanele ifakwe i-valve yokukhipha. Kodwa-ke, ekusetshenzisweni kwangempela, iningi lamasistimu okupholisa amanzi ngaphandle kwe-valve yokukhipha lifakiwe. Lapho isithando somlilo singasebenzi isikhathi eside, igesi kulula ukungena kusihlukanisi samanzi. Lapho isithando somlilo sokuncibilikisa insimbi siqala phansi, ingxenye yegesi izosala kusihlukanisi samanzi kanye nebhokisi lamanzi elipholisayo lezinto futhi ngeke ikwazi ukukhishwa, okuholela ekwehlulekeni kwale ngxenye. Ukupholisa kwamanzi ajikelezayo kubangela ukuthi izinga lokushisa libe phezulu kakhulu ukushisa izingxenye. Ngakho-ke, uhlelo lokupholisa amanzi ngaphandle kwe-valve yokukhipha alusetshenziswa isikhathi eside, futhi luyasebenza futhi. Uqinisa lwamanzi endaweni ephezulu kakhulu yokuhlukanisa amanzi kufanele kukhululwe ukukhipha igesi esele.
