IiHydrogenerators zinokwahlulwa zibe ziintlobo ezithe nkqo nezithe tye ngokweendawo zazo ze-axis. Iiyunithi ezinkulu neziphakathi zihlala zisebenzisa uyilo oluthe nkqo, kwaye uyilo oluthe tye luhlala lusetyenziswa kwiiyunithi ezincinci nezineetyhubhu. Iihydro-generators ezithe nkqo zahlulwe zibe ziintlobo ezimbini: ukumiswa...Funda ngokugqithisileyo»

Ukuba ivalvu yebhola yejenereyitha yamanzi ifuna ukuba nexesha elide lokusebenza kwaye ingabi nakugcinwa ixesha elide, kufuneka ixhomekeke kwezi zinto zilandelayo: Iimeko zokusebenza eziqhelekileyo, ukugcina umlinganiselo wobushushu/uxinzelelo oluhambelanayo kunye nedatha yokugqwala efanelekileyo. Xa ivalvu yebhola ivaliwe, kusekho i-p...Funda ngokugqithisileyo»

1. Iintlobo kunye neempawu zokusebenza kwejenereyitha Ijenereyitha sisixhobo esivelisa umbane xa siphantsi kwamandla oomatshini. Kule nkqubo yokuguqula, amandla oomatshini avela kwiintlobo ngeentlobo zamandla, njengamandla omoya, amandla amanzi, amandla obushushu, amandla elanga kunye...Funda ngokugqithisileyo»

I-hydro-generator yenziwe nge-rotor, i-stator, ifreyimu, i-thrust bearing, i-guide bearing, i-cooler, i-brake kunye nezinye izinto eziphambili (jonga umfanekiso). I-stator yenziwe ikakhulu ngesiseko, i-iron core, kunye ne-windings. I-stator core yenziwe ngamashiti esinyithi e-silicon aqengqelekayo abandayo, anokwenziwa abe...Funda ngokugqithisileyo»

Kukho iintlobo ezininzi zeejenereyitha zamanzi. Namhlanje, ndiza kwazisa ngokweenkcukacha iijenereyitha zamanzi ze-axial flow. Ukusetyenziswa kweejenereyitha ze-axial flow turbine kwiminyaka yakutshanje ikakhulu kukuphuhliswa kweentloko eziphakamileyo kunye nobukhulu obukhulu. Ii-turbine zasekhaya ze-axial-flow zikhula ngokukhawuleza....Funda ngokugqithisileyo»

Ukuqhubela phambili, ngokubhekisele koku, ungacinga ngenkqubela phambili yokufumana izatifikethi zobungcali, ezifana ne-CET-4 kunye ne-CET-6. Kwimoto, imoto ikwanazo nezigaba. Olu luhlu apha alubhekiseli kubude bemoto, kodwa kwisantya esihambelanayo semoto. Masithathe inqanaba lesi-4...Funda ngokugqithisileyo»

Ijenereyitha ye-hydro yenziwe nge-rotor, i-stator, ifreyimu, i-thrust bearing, i-guide bearing, i-cooler, i-brake kunye nezinye izinto eziphambili (jonga uMfanekiso). I-stator yenziwe kakhulu ngefreyimu, i-iron core, i-winding kunye nezinye izinto. I-stator core yenziwe ngamashiti esinyithi e-silicon aqengqelekayo abandayo, anokwenziwa...Funda ngokugqithisileyo»

1. Ulwahlulo lomthamo kunye nodidi lwejenereyitha yamanzi Okwangoku, akukho mgangatho udibeneyo wokwahlulwahlulwa komthamo kunye nesantya sejenereyitha yamanzi ehlabathini. Ngokwemeko yaseTshayina, umthamo wayo kunye nesantya sayo zinokwahlulwa ngokwetafile elandelayo: Udidi...Funda ngokugqithisileyo»

1. Ngaphambi kokulungiswa, ubungakanani bendawo yeendawo eziqhekekileyo kufuneka bucwangciswe kwangaphambili, kwaye kufuneka kuqwalaselwe umthamo owaneleyo wokuthwala, ingakumbi ukubekwa kwerotor, ifreyimu ephezulu kunye nefreyimu esezantsi ekulungisweni okanye ekulungisweni okwandisiweyo. 2. Zonke iindawo ezibekwe kumhlaba we-terrazzo sha...Funda ngokugqithisileyo»

Iindlela zokuvelisa umbane zangoku eTshayina ziquka oku kulandelayo: (1) Ukuveliswa kombane obushushu. Isikhululo samandla obushushu ngumzi-mveliso osebenzisa amalahle, ioyile, kunye negesi yendalo njengepetroli ukuvelisa umbane. Inkqubo yaso esisiseko yemveliso yile: ukutshiswa kwamafutha kuguqula amanzi kwibhoyila abe ngumphunga, kwaye ...Funda ngokugqithisileyo»

I-US Energy Information Administration (EIA) isandula ukukhupha ingxelo ethi ukusukela ehlotyeni lalo nyaka, imozulu eyomileyo kakhulu ithwaxe i-United States, nto leyo ebangele ukuba ukuveliswa kwamandla ngamanzi kwiindawo ezininzi zelizwe kwehle kangangeenyanga eziliqela ezilandelelanayo. Kukho ukunqongophala kwamandla ombane...Funda ngokugqithisileyo»
