Izityalo zamandla ombane ezihamba nge-axial-flow, ezixhotyiswe ngee-turbines zaseKaplan, zilungele iindawo ezinezinga eliphantsi ukuya kweliphakathi lokuhamba kwamanzi kunye nezinga elikhulu lokuhamba kwamanzi. Ezi turbines zisetyenziswa kakhulu kwiiprojekthi zamadama okusebenzisa amanzi amdaka kunye namanzi amdaka ngenxa yokusebenza kakuhle kunye nokuguquguquka kwazo. Impumelelo yokufakelwa kombane onjalo ixhomekeke kakhulu kwimisebenzi yoluntu eyilwe kakuhle neyenziweyo ngononophelo, eyakha isiseko sokusebenza kwee-turbine, uzinzo lokusebenza, kunye nokhuseleko.
1. Ukulungiswa Kwendawo Nokujika Umlambo
Ngaphambi kokuba kuqalwe naluphi na ulwakhiwo olukhulu, ukulungiswa kwendawo kubalulekile. Oku kuquka ukucoca indawo yokwakha, ukuseta iindlela zokufikelela, kunye nokuseka inkqubo yokuphambukisa umlambo ukuze kulungiswe indlela yamanzi kwaye kudale indawo yokusebenza eyomileyo. IiCofferdams—iindawo zokuvala okwethutyana ezakhiwe ngaphakathi okanye ngaphesheya komlambo—zidla ngokusetyenziselwa ukwahlula indawo yokwakha emanzini.
2. Ulwakhiwo lokungenisa
Ulwakhiwo lokungenisa amanzi lulawula ukungena kwamanzi kwisityalo samandla kwaye luqinisekisa ukuba amanzi ahamba kakuhle kwi-turbine ngaphandle kwenkunkuma. Luquka iindawo zokulahla inkunkuma, iingcango, kwaye ngamanye amaxesha iindawo zokuhlamba inkunkuma. Uyilo olufanelekileyo lwe-hydraulic lubalulekile ukuthintela ukwakheka kwe-vortex, ukunciphisa ukulahleka kweentloko, kunye nokukhusela i-turbine kwinkunkuma edadayo.
3. I-Penstock okanye i-Open Channel
Ngokuxhomekeke kuyilo, amanzi asuka kwindawo yokungenisa amanzi athunyelwa kwi-turbine nge-penstocks (iipayipi ezivaliweyo) okanye iitshaneli ezivulekileyo. Kwiindlela ezininzi zoyilo lwe-axial-flow—ingakumbi kwizityalo ezisezantsi—kusetyenziswa indawo yokungenisa amanzi evulekileyo eqhagamshelwe ngqo kwi-turbine. Uzinzo lwesakhiwo, ukufana kwendlela yokuhambisa amanzi, kunye nokunciphisa ilahleko ze-hydraulic zezona zinto zibalulekileyo ngeli nqanaba.
4. Ulwakhiwo lwePowerhouse
Le ndlu yamandla igcina iyunithi yejenereyitha yeturbine, iinkqubo zolawulo, kunye nezixhobo ezincedisayo. Kwiiturbine zeKaplan, ezihlala zifakelwa ngokuthe nkqo, indlu yamandla kufuneka yenzelwe ukuxhasa imithwalo emikhulu ye-axial kunye namandla aguqukayo. Uzinzo lokungcangcazela, ukuthintela amanzi, kunye nokufikelela lula kulondolozo ziinkalo ezibalulekileyo zoyilo lwesakhiwo.
5. Ityhubhu yokudonsa kunye neTailrace
Ityhubhu yokukhupha amanzi idlala indima ebalulekileyo ekufumaneni amandla e-kinetic emanzini aphuma kwi-turbine. Ityhubhu yokukhupha amanzi eyilwe kakuhle yonyusa ukusebenza kakuhle. Umjelo womsele wamanzi uhambisa amanzi ngokukhuselekileyo emlanjeni. Zombini izakhiwo zifuna ukumila ngendlela echanekileyo ukunciphisa i-turbulence kunye nemiphumo yamanzi angasemva.
6. Igumbi loLawulo kunye neZakhiwo eziNcedisayo
Ngaphandle kwezakhiwo eziphambili, imisebenzi yokwakha ikwabandakanya ukwakhiwa kwamagumbi olawulo, iindawo zokuhlala zabasebenzi, iiworkshops, kunye nezinye izakhiwo zokusebenza. Ezi zakhiwo ziqinisekisa ukusebenza okuthembekileyo kwezityalo kunye nokugcinwa kwazo ixesha elide.
7. Izinto eziqwalaselwayo malunga nokusingqongileyo kunye neJografi
Uphando lomhlaba, ukuzinzisa amathambeka, ulawulo lokukhukuliseka komhlaba, kunye nokukhuselwa kwendalo zizinto ezibalulekileyo kucwangciso loluntu. Iinkqubo zokuhambisa amanzi ngendlela efanelekileyo, iindlela zeentlanzi (apho kufuneka khona), kunye nomsebenzi wokulungisa umhlaba kunceda ekunciphiseni impembelelo yokusingqongileyo yeprojekthi.
Icandelo lobunjineli bokwakha lesityalo samandla ombane esihamba nge-axial-flow libalulekile ekusebenzeni kwaso ngokubanzi kunye nobude baso. Isakhiwo ngasinye—ukusuka kwindawo yokungenisa ukuya kwindawo yokubuyela umva—kufuneka siyilwe ngononophelo kwaye sakhiwe ukuze simelane namandla amanzi, iimeko zejoloji, kunye neemfuno zokusebenza. Intsebenziswano esondeleyo phakathi kweenjineli zokwakha, ababoneleli bezixhobo zamandla ombane, kunye neengcali zokusingqongileyo kubalulekile ekunikezeni isisombululo samandla ombane esikhuselekileyo, esisebenzayo, nesizinzileyo.
