Cov ntaub ntawv tseem ceeb siv nyob rau hauv hnub ci- lub tshuab nqus dej twj tso kua mis (tseem hu ua photovoltaic dej twj) sib txawv nyob ntawm cov khoom thiab daim ntawv thov. Txawm li cas los xij, cov khoom tseem ceeb (tshwj xeeb tshaj yog cov neeg nyob rau hauv kev sib cuag nrog dej) feem ntau siv corrosion-tiv taus, siab- cov ntaub ntawv muaj zog kom ntseeg tau tias muaj kev ntseeg siab nyob rau sab nraum zoov, kev ua haujlwm ntev -, thiab cov dej sib txawv.
Stainless hlau: Qhov no yog cov khoom siv ntau tshaj plaws nyob rau hauv hnub ci- lub zog nqus dej twj tso kua mis, tshwj xeeb tshaj yog rau cov khoom siv tseem ceeb xws li lub twj tso kua mis lub cev, impeller, thiab ncej. 304 stainless hlau yog dav siv hauv kev ua liaj ua teb irrigation thiab tob tob dej extraction vim nws zoo heev corrosion kuj, tsawg - kub tsis kam, thiab txhua yam muaj zog. Piv txwv li, qee cov khoom lag luam qhia meej meej tias lawv yog cov hlau tsis muaj steel, haum rau cov dej huv huv, thiab tuaj yeem tiv taus qhov kub thiab txias li -15 degree.
Engineering Plastics: Qee lub twj tso kua mis lossis cov hauv ob sab phlu yog ua los ntawm cov yas engineering xws li polypropylene (PP), ultra-siab molecular hnyav polyethylene (UHMWPE), thiab perfluoroethylene propylene (FEP). Cov no feem ntau yog siv rau kev xa cov dej nrog me ntsis corrosiveness los yog muaj cov khoom, thiab muaj qhov zoo xws li lub teeb yuag, corrosion kuj, thiab tus nqi qis.
Ceramic: Nyob rau hauv siab -kawg los yog submersible photovoltaic dej twj tso kua mis, ceramic bushings thiab shafts feem ntau yog siv los ua kom tiav waterproofing (IP68) thiab hnav- ua haujlwm pub dawb, ua ke nrog cov qauv tsav sib nqus, ua kom muaj kev ua haujlwm tsis muaj txhuam thiab ua haujlwm ntev.
Cam khwb cia hlau: Hauv qee qhov tsoos lossis siab - lub tshuab hluav taws xob, lub twj tso kua mis lub cev tuaj yeem ua los ntawm cov hlau cam khwb cia, tab sis nws feem ntau yuav tsum muaj kev tiv thaiv nto - kev kho corrosion kom tiv taus qhov chaw sab nraum zoov.
