Muuqaalka tamarta nadiifka ah, korontada biyaha ayaa ah tiir muhiim ah oo ka mid ah isbeddelka tamarta, taas oo ay ugu wacan tahay dabeecaddeeda la cusboonaysiin karo, qiimaha jaban, iyo awoodaha dheelitirka culeyska ugu sarreeya. Laga bilaabo matoorrada waaweyn ee Biyo-xidheenka Saddexda Gorges ilaa socodka jilicsan ee warshadaha yar yar ee korontada biyaha ee gobollada buuraleyda ah, wareegga matoorrada waxaa had iyo jeer la socda beddelka tamarta laga bilaabo "tamarta biyaha ee suurtagalka ah → tamarta farsamada → tamarta korontada." Soo jiidashada ugu weyn ee korontada biyaha waxay ku jirtaa la qabsiga cajiibka ah ee cutubka matoorrada korontada biyaha ee xaaladaha biyaha iyo socodka kala duwan. Qaabkan muujinta firfircoon, iyada oo loo marayo nuqul sax ah oo noocyada matoorrada caadiga ah sida matoorrada falcelinta iyo matoorrada kicinta, wuxuu muujinayaa hal-abuurka gaarka ah ee isdhexgalka u dhexeeya matoorrada iyo socodka biyaha. (1) Qaabka Matoorrada Falcelinta: Isweydaarsiga Tamarta "Qabanaya" ee u dhexeeya Socodka Biyaha iyo Daabyada Qaabka matoorrada Francis waa kan ugu isticmaalka badan "dhammaystiran." Qaabku wuxuu soo saaraa qaab-dhismeedka asaasiga ah ee cutub 700MW ah oo ku yaal Saldhigga Korontada Saddexda Gorges oo ah miisaan 1:25 ah. Orod-wade wuxuu leeyahay dhexroor dhan 30cm wuxuuna ka kooban yahay 13 daab oo siman (xagal 15° ah, xagal 20° ah) oo si radial ah loo habeeyay; hareeraha orod-wade waxaa ku wareegsan tuubooyin hagitaan oo la hagaajin karo (24 van, oo laga sameeyay balaastiig ABS iyo qaab-dhismeed bir ah), oo ku xiran "giraan governor ah," kaas oo hagaajin kara furitaanka tuubada hagaha (0-30°). Daboolka hufan wuxuu ka samaysan yahay acrylic la shubay. Biyuhu (laga bilaabo nidaamka biyaha wareegaya oo uu wado bamka yar) waxay si siman ugu qulqulaan dahaarka dhinacyada oo dhan, iyadoo ay hagayaan tuubooyinka hagaha, waxayna saameeyaan daabyada orodka xawaare socod oo la sawiray oo ah 20m/s, taasoo kaxeynaysa orod-wade inuu wareego (150 rpm, oo u dhiganta 125 rpm cutubka dhabta ah). Xuddunta bandhigga firfircoon waxay ku jirtaa beddelka tamarta ee "qaadashada biyaha wareegsan": Marka furitaanka tuubada hagaha loo hagaajiyo 20°, mitirka socodka wuxuu muujinayaa "heerka socodka la sawiray 5L/s", mitirka xawaaraha wuxuu xasilaa 150 rpm, qaabka matoorkuna wuxuu soo saaraa 220V. Marka la jilaynayo "socodka oo kordha xilliga daadadka" (hagaha vane-ka si buuxda ayuu u furan yahay), xawaaraha turbine-ku wuxuu kordhaa ilaa 180 rpm, danabkuna wuxuu gaaraa 240V. Shaashadu waxay isku mar soo bandhigaysaa "turbine-yada Francis waxay ku habboon yihiin madaxyada biyaha ee 50-700m waxayna gaari karaan hufnaan 95%. Naqshaddani waxay ka dhigaysaa mabda'a falcelinta ee "kala duwanaanshaha cadaadiska labada dhinac ee daabyada wada turbine-ka" mid dareen leh, iyadoo si fiican u sharraxaysa sababta turbine-yada Francis ay yihiin doorashada la doorbidayo ee madaxa biyaha sare iyo heerarka socodka weyn. Qaabka turbine-ka socodka axial-ka wuxuu muujinayaa faa'iidooyinka "qaadashada biyaha axial" ee madaxyada biyaha ee hooseeya, oo leh labadaba noocyada daabyada go'an iyo kuwa la hagaajin karo. Qaabka daabyada la hagaajin karo wuxuu leeyahay rotor dhexroorkiisu yahay 40cm oo leh 6 daab oo wareegaya iyadoo loo eegayo xaaladaha socodka biyaha (oo ay xakamayso matoorka servo-ga yar), oo leh kala duwanaansho hagaajin xagal daab ah oo u dhexeeya -10° ilaa +15°. Vane-ka hagaha iyo rotor-ka si isku xiran ayaa loo habeeyay, iyadoo biyuhu si axial ah ugu socdaan rotor-ka. Daabyadu waxay ku wareegaan saamaynta isku dhafan ee riixitaanka biyaha iyo wareeggooda. Muuqaalka is-dhexgalka ee "hagaajinta madaxa biyaha" ee qaabkani waa mid gaar ah: Marka dhagaystayaashu ay doortaan "madaxa biyaha oo hooseeya 3-5m" (tusaale ahaan, webi ku yaal meel bannaan), xagasha daabka waxaa loo hagaajiyaa +15° (kordhinta aagga taabashada biyaha), furitaanka vane-ka hagaha waa 30°, xawaaraha rotor-kuna waa 60 rpm; u beddelashada "madaxa biyaha ee dhexdhexaadka ah 10-30m", xagasha daabka waxaa loo hagaajiyaa 0°, xawaaruhu wuxuu kordhaa 100 rpm, shaashaduna waxay soo bandhigaysaa "maraakiibta socodka axial waxay gaari karaan hufnaan 92% heerarka socodka sare iyo madaxyada biyaha oo hooseeya". Muujinta isbarbardhigga ah ee maraakiibta socodka la hagaajin karo iyo kuwa go'an waxay leedahay qiimo waxbarasho oo weyn: Heerka socodka isku midka ah, maraakiibta socodka la hagaajin karo, iyadoo la hagaajinayo xagasha daabka, waxay gaartaa hufnaan 8-10% ka sarreysa maraakiibta go'an (qalooca hufnaanta waxaa lagu soo bandhigayaa waqtiga dhabta ah shaashadda), iyadoo si dareen leh u muujineysa faa'iidada farsamo ee "maraakiibta socodka la hagaajin karo ee awood u leh inay la qabsadaan heerarka socodka oo ballaaran." Isbarbardhiggani wuxuu si gaar ah muhiim ugu yahay baridda korontada yar yar ee meelaha waraabka, isagoo ka caawinaya ardayda inay fahmaan "sababta loo isticmaalo marawaxadaha socodka axial-ka ee mashaariicda korontada yar yar ee miyiga." Qaabka marawaxadaha socodka ee u janjeera waa "sayid u ah la qabsiga madaxa," iyadoo dhidibka daabka orodka uu ku yaal xagal 45° ilaa usha ugu weyn (inta u dhaxaysa socodka isku dhafan iyo marawaxadaha socodka axial-ka). Daabyada moodeelka waxaa si isku mid ah loogu hagaajin karaa (laga bilaabo -5° ilaa +25°), iyadoo muraayadaha hagaha iyo orodku ay isku hagaajinayaan. Marka madaxa la sawiray uu ka kordho 40m ilaa 120m, xagasha daabka si toos ah ayay uga soo hagaagtaa +25° ilaa -5°, iyadoo la ilaalinayo xawaaraha orodka ee deggan ee 120 rpm, taasoo muujinaysa astaamaha "waxtarka sare ee kala duwanaanshaha madaxa 3-laaban." Daboolka hufan wuxuu u oggolaanayaa in si cad loo fiirsado waddada socodka gaarka ah, khariidadda qaab-dhismeedka hufnaanta ee shaashadda waxay ka caawisaa daawadayaasha inay fahmaan "iswaafajinta u dhaxaysa marawaxadaha socodka isku dhafan iyo kuwa socodka axial-ka."
(2) Qaabka Turbine-ka ee Kacsan: Sii deynta Tamarta ee Socodka Biyaha iyo Daabyada "Shil"
Qaabka turbine-ka Pelton waa "horyaalka awoodda" ee codsiyada madaxa sare leh, isagoo ku dayanaya naqshadda caadiga ah ee saldhigga korontada Leonhard ee Switzerland. 12 baaldi oo qaab koob ah (mid walba oo leh awood 50mL ah, oo laga sameeyay naxaas chrome-plated) ayaa si siman ugu baahsan orodka (dhexroorka 25cm); "buluugga" (dhexroorka 0.5cm) wuxuu ku wareegaa 360°. Biyaha cadaadiska sare leh (oo ay bixiyaan bamka plunger-ka, oo ku dayanaya madaxa 500-1000m) waxay sameeyaan jet xawaare sare leh (50m/s) oo si sax ah u saameeya "kala-qaybiyaha" baaldiyada, taasoo tamarta dhaqdhaqaaqa biyaha u beddesha tamarta farsamada ee orodka wareegaya. Waxa ugu muhiimsan ee muujinta firfircoonidu waa wareejinta tamarta iyada oo loo marayo "saamaynta jet": Marka hal buluugga la hawlgeliyo, jet-ka biyaha ee saameeya giraangiraha turbine-ka wuxuu abuuraa "xoog falcelin" oo la dareemi karo (dardargelinta degdegga ah ee rotor-ka), oo gaaraya 300 rpm iyo awood soo saar matoor oo la jilay oo ah 500W. Iyada oo leh laba tuubo (si siman loo habeeyay), xawaaruhu wuxuu gaarayaa 580 rpm iyo awoodda ilaa 980W. Shaashadu waxay muujinaysaa in "waxtarka noocan ah ee marawaxadaha uu gaari karo 90% marka uu gaaro madaxa biyaha sare, biyuhuna aysan gelin dahaarka, taasoo ka dhigaysa mid ku habboon biyaha leh qoyaan sare." Naqshaddani waxay si cad u muujinaysaa mabda'a ah in "wareejinta tamarta kinetic-ga aysan ku xirnayn cadaadiska biyaha, laakiin kaliya saameynta socodka biyaha xawaaraha sare leh," si fiican u sharraxaysa sababta ay ugu habboon tahay "warshadaha korontada biyaha ee buuraha leh oo leh madax ka badan 100m." Qaabka marawaxadaha ee saamaynta u janjeera wuxuu muujinayaa la qabsiga dabacsan ee "saamaynta jet-ka ee oblique," iyadoo afka uu u janjeero 22.5° diyaaradda giraangiraha, biyuhu si aan sinnayn ayay u saameeyaan daabyada qaabka qaadada (18 daab). Sifada is-dhexgalka ah waxay u oggolaanaysaa daawadayaasha inay hagaajiyaan xagasha afka, iyagoo eegaya isbeddelka xawaaraha rotor-ka - hoos u dhac 10-15% ah marka xagashadu ka leexato 22.5°, taasoo muujinaysa saameynta saxnaanta xagasha ee waxtarka. Noocan noocan ah waxaa badanaa loo isticmaalaa in lagu muujiyo "koronto yar oo ku taal meelaha buuraleyda ah," oo ku habboon "nidaamyada tamarta ee la qaybiyey oo leh madax 20-300m ah iyo heerarka socodka yar." Qaabka turbine-ka ee saamaynta laba-geesoodka ah wuxuu kordhiyaa isticmaalka tamarta isagoo "biyuhu laba jeer saameeyaan daabyada." Giraangiraha turbine-ku wuxuu leeyahay laba lakab oo daabyo ah; ka dib saameynta koowaad, biyuhu waxay dhex maraan giraangiraha si ay u saameeyaan lakabka hoose. Giraangiraha hufan wuxuu u oggolaanayaa daawadayaasha inay arkaan wadada "saamaynta laba-geesoodka ah". Shaashadu waxay muujinaysaa in "in kasta oo waxtarka naqshadeynta saamaynta laba-geesoodka ah ay waxoogaa ka hooseeyaan (75-85%), qaab-dhismeedkeeda fudud iyo kharash yar ay ka dhigayaan mid ku habboon korontada yar-yar ee miyiga." Naqshaddani waxay si fudud u muujinaysaa "xigmadda isticmaalka tamarta ee naqshadaha fudud". (3) Noocyada Gaarka ah ee Moodooyinka Turbine-ka Hydro: Naqshado Cusub oo loogu talagalay Xaaladaha Ba'an
Qaabka turbine-ka nalka waa xal "fidsan" oo loogu talagalay warshadaha korontada biyaha ee madaxa hoose. Waxay leedahay qaab-dhismeed "qaab guluub" ah - matoorku wuxuu ku yaal gudaha qolof qaab guluub ah oo ku yaal waddada socodka biyaha, rotor-ka turbine-kuna si toos ah ayuu ugu xiran yahay usha matoorka (ma laha dahaarka wareega). Biyuhu si dhidibada ah ayay ugu socdaan cutubka. Dhererka madaxa ee la sawiray ee 2-8m (tusaale ahaan, warshadaha korontada ee mowjadaha), rotor-ka (dhexroorka 40cm, 8 daab oo qaloocan) wuxuu ku wareegaa 80 rpm. Shaashadu waxay soo bandhigaysaa "turbine-ka nalka wuxuu gaari karaa waxtarka ilaa 88%, oo ku habboon warshadaha korontada ee webiyada, iyadoo leh kharashyo injineernimo madani ah oo hooseeya." Daboolka hufan wuxuu si cad u muujinayaa astaamaha "socodka biyaha ee tooska ah", isagoo sharraxaya isticmaalkiisa ballaaran ee codsiyada madaxa hoose sida kanaalada mowjadaha iyo waraabka. Qaabka turbine-ka mowjadaha wuxuu muujinayaa soo saarista korontada laba geesoodka ah. Daabyadeeda rotor-ka waxay leeyihiin naqshad "qaab S" oo siman, taasoo u oggolaanaysa rotor-ku inuu wareego iyadoon loo eegin haddii biyuhu ka socdaan bidix ilaa midig ama midig ilaa bidix (60 rpm). Qaabkani wuxuu ku xiran yahay "taangi jilitaan mowjad ah," kaas oo isticmaala heerarka biyaha ee kor u kacaya iyo kuwa hoos u dhacaya si loo abuuro socod isdhaafsi ah, isagoo muujinaya wareegga "soo saarista tamarta inta lagu jiro hirarka sare → korontada inta lagu jiro hirarka hoose → xidhitaanka inta lagu jiro hirarka aan degganayn." Shaashadda waxay soo bandhigaysaa "Terbine-yada mowjadu waxay isticmaalaan cufis-jiidka dayaxa, waa la cusboonaysiin karaa, waana kuwo aad loo saadaalin karo." Naqshaddani waxay ka dhigaysaa isku-dhafka u dhexeeya "tamarta nadiifka ah iyo laxanka dabiiciga ah" mid muuqata.
