1) khangela ukuba umgangatho wokwakha, ukuveliswa kunye nofakelo lomgangatho wobunjineli boluntu uyahlangabezana neemfuno zoyilo kunye nemimiselo efanelekileyo kunye neenkcukacha.
2) Ngokuhlola ngaphambi nangemva kokusebenza kovavanyo, umsebenzi olahlekileyo okanye ongagqitywanga kunye neziphene zeprojekthi kunye nezixhobo zinokufumaneka ngexesha.
3) Ngokuqalisa kunye nokusebenza kovavanyo, qonda ukufakwa kwezakhiwo zehydraulic kunye nezixhobo ze-electromechanical, lawula ukusebenza kwezixhobo ze-electromechanical, ukulinganisa idatha ethile efunekayo yobugcisa esebenzayo, kwaye urekhode ezinye izixhobo ze-curves njengenye yesiseko esisisiseko sokusesikweni. ukusebenza, ukuze kulungiswe iinkcukacha zobugcisa eziyimfuneko ukulungiselela imigaqo yokusebenza yeplanti yamandla.
4) Kwezinye iiprojekthi zombane wamanzi, uvavanyo lweempawu zobuchule beyunithi yejenereyitha ye-iturbine yamanzi nalo luyenziwa.Ukuqinisekisa ixabiso lesiqinisekiso esisebenzayo somenzi kunye nokubonelela ngedatha yokusebenza koqoqosho lweplanti yamandla.
25. Yintoni injongo yovavanyo olukhawulezayo lweyunithi?
Impendulo: 1) khangela umgangatho wolawulo lwesixhobo sokuvuselela ngokuzenzekelayo seyunithi;2) Qonda indawo yokungcangcazela kweyunithi phantsi komthwalo;3) Khangela kwaye uqinisekise ixabiso eliphezulu lokunyuka kweyunithi yedatha elawulayo, ixabiso eliphezulu lokunyuka koxinzelelo phambi kwe-vane yesikhokelo kunye ne-coefficient yohlengahlengiso oluhlukeneyo lwerhuluneli;4) Ukuqonda umthetho wokutshintsha kweempawu zangaphakathi ze-hydraulic kunye ne-mechanical yeyunithi kunye nefuthe layo kumsebenzi weyunithi, ukwenzela ukuba unikeze idatha efunekayo yokusebenza ngokukhuselekileyo kweyunithi;5) Chonga uzinzo kunye nokunye ukusebenza kwerhuluneli.
26. Uluqhuba njani uvavanyo lwe-static balance ye-hydraulic turbine?
Impendulo: beka iigeyiji zenqanaba ezimbini kwi-X kunye ne-Y bisectors yeringi esezantsi yembaleki;Beka ibhalansi ubunzima obunobunzima obufanayo nenqanaba elilinganayo kwi-bisector of - X kunye ‐ y (ubunzima bayo bungabalwa ngokofundo lwenqanaba);Ngokwenqanaba lenqanaba, beka ubunzima bokulinganisa kwicala lokukhanya kude kube ibhulu lenqanaba libekwe phakathi, kwaye ubhale phantsi ubungakanani beP kunye ne-azimuth yobunzima bokugqibela bokulinganisa α
27. Uyitsala njani i-thrust head ngexesha logcino?
Impendulo: susa i-screw yokudibanisa phakathi kwentloko ye-thrust kunye nepleyiti yesibuko, xhoma i-thrust head kumsele omkhulu ngentambo yentsimbi kwaye uyiqinise kancinane.Phakamisa impompo yeoli, vala i-rotor, yongeza iipads ezine ze-aluminium phakathi kwentloko yokuphosa kunye nepleyiti yesibuko kwi-90 degree orientation, khupha ioli kwaye ulahle i-rotor.Ngale ndlela, i-shaft ephambili yehla kunye ne-rotor, kwaye intloko ye-thrust inamathele kwi-pad kwaye ikhutshwe kude.Phinda amatyeli aliqela, lawula ubukhulu be-cushion phakathi kwe-6-10mm ngexesha ngalinye, kwaye ngokuthe ngcembe uyikhuphe i-thrust head de ibe inokunyuswa ngaphandle ngehuku engundoqo.Emva kokutsala amatyeli amaninzi, intsebenziswano phakathi kwentloko yokutyhala kunye ne-shaft engundoqo iyakhululeka, kwaye intloko yokuphosa inokutsalwa ngokuthe ngqo nge-crane.28. Jonga le theyibhile ilandelayo ukuze ufumane irekhodi yokujika ye-1# iturbine (iyunithi: 0.01mm):
Bala ujingi olupheleleyo kunye nokujingisa kwenethi yesikhokelo soxinzelelo lwehydraulic, isikhokelo esisezantsi kunye nesikhokelo esiphezulu, kwaye ugqibezele le theyibhile ingentla.
