Muva nje, iqoqo lezincwadi ezenziwe ngokwezifisoiziteshi ze-penstockkusuka efektri yethu kudlule ukuhlolwa komkhiqizo okuphelele, kwapakishwa futhi kwathunyelwa endaweni yephrojekthi yemisebenzi yamanzi eSingapore. Lezi zingcezu zokhuni zinobukhulu obungu-250×500mm, zenziwe ngensimbi yekhabhoni ye-Q235B ene-hot-dip galvanized anti-corrosion coating, esetshenziswa kabanzi ekuhlinzekweni kwamanzi kamasipala aphesheya kwezilwandle kanye nokuthuthwa kwamanzi, iziteshi zokunisela zasemapulazini kanye namaphrojekthi okwelapha amanzi angcolile.

Lolu chungechunge lwezikhonkwane zensimbi yekhabhoni ezisetshenziswa ngesandla lunezinzuzo zobuchwepheshe ezivelele. Njengoba ifakwe i-actuator ye-turbine evulekile, i-turbine drive inikeza i-torque enkulu yokuvula nokuvala kalula ngaphandle kokunikezwa kwamandla. Isembozo sokuvikela isiqu esisodwa sihlonyiselwe ukuvimba indle, amanzi emvula kanye nemfucumfucu, sivikele intambo yesikulufu futhi sandise kakhulu impilo yesevisi. Njengoba isebenzisa ukuvalwa okuhlanganisiwe okuthambile okuqinile okunezinhlangothi ezimbili, i-penstock ayitholi ukuvuza nhlobo ezinhlangothini zombili ezingenhla nangezansi ngokumelana okuqinile kwengcindezi, ivumelana ngokuphelele nendawo yokusebenza enomswakama nenemvula yaseSingapore.

Uhlaka kanye nepuleti lesango kuhlanganiswe ngokuphelele nge-hot-dip galvanizing coating efanelekile, okuletha ukumelana okuhle kakhulu kokugqwala nokugqwala, okulungele iziteshi ezinamanzi olwandle, indle kanye nemidiya ene-acid encane noma i-alkaline. Isakhiwo se-modular senza kube lula ukufakwa endaweni, futhi izingxenye zokuvala zingashintshwa ngaphandle kokuzihlukanisa ngokuphelele, okunciphisa kakhulu izindleko zokulungisa zamakhasimende.

Sinikeza osayizi abakhelwe ngokwezifiso, ama-actuator (i-turbine yesandla / i-actuator kagesi), ukwelashwa kokulwa nokugqwala kanye namazinga okuvala amaphrojekthi aseNingizimu-mpumalanga ye-Asia, ngezitifiketi eziphelele zomhlaba wonke ezifaka phakathi i-CE ne-ISO. Imikhiqizo yethu ithunyelwa eSingapore, eMalaysia, e-Indonesia nakwamanye amazwe aseNingizimu-mpumalanga ye-Asia ukuze kwakhiwe ingqalasizinda yamanzi.

Lokhu kulethwa okuphumelelayo eSingapore kuyaqaphela ngokugcwele ubuciko bethu bokukhiqiza, amazinga okulwa nokugqwala kanye nokusebenza kokuvala okuthembekile. Sizoqhubeka sigxile emakethe yemishini yamanzi yomhlaba wonke, sihlinzeka ngama-channel penstocks angabizi futhi ahlala isikhathi eside, amasango amaslayidi kanye namasango e-weir kumaphrojekthi kamasipala, ezemvelo kanye nokunisela emhlabeni jikelele.
