Ngo-Agasti ka-2018, i-CONVISTA ithuthukise ngempumelelo Amavalufu Wesango Leslayidi Esihambisanayo ukuze uthole amasistimu amapayipi omfutho ophezulu kanye naphakathi angu-600 kuya ku-1,000MW supercritical (ultra-supercritical) unit steam turbine.
I-1.Isebenzisa isakhiwo sokuzivala ingcindezi, esinoxhumano olushiselwe emikhawulweni yomibili.
I-2.Isebenzisa i-valve ye-bypass kagesi endaweni yokungena kanye ne-outlet yokulinganisa ingcindezi ehlukile ekungeneni nasekuphumeni.
3. Indlela yayo yokuvala isebenzisa ukwakheka kwe-flashboard ehambisanayo. Ukuvalwa kwevaluvu kuvela kumfutho ophakathi nendawo esikhundleni sokusuka emandleni abambekayo emishini ukuze kuvinjwe ivalvu ekucindezelekeni okuyingozi phakathi nokuvula nokuvala kwayo.
4. Nge-cobalt-based rigid alloy build-up welding, ubuso obuvaliwe bufaka ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nokuhuzuka, impilo ende yesevisi nezinye izici.
5. Ukwelashwa kwe-anti-corrosion kanye ne-nitrogenization, i-valve stem surface ifaka ukumelana nokugqwala okuhle, ukumelana nokuhuzuka kanye nokuvalwa kwebhokisi lokugxusha okuthembekile.
6. Ingakwazi ukuhambisana namadivayisi ahlukahlukene kagesi asekhaya nangaphandle ukuze ihlangabezane nezidingo zokulawula i-DCS futhi ibone ukusebenza okukude nendawo.
7. Izovulwa ngokugcwele noma ivalwe ngesikhathi sokusebenza. Akumele isetshenziswe njenge-valve yokulawula.
