Ii-Water Turbine Runners: Iintlobo kunye neenkcukacha zobugcisa

Iiturbine zamanzi zizinto ezibalulekileyo kwiinkqubo zamanzi, ziguqula amandla amanzi ahambayo okanye awelayo abe ngamandla oomatshini. Intliziyo yale nkqubo ikwiimbaleki, inxalenye ejikelezayo yeturbine esebenzisana ngokuthe ngqo nokuhamba kwamanzi. Uyilo, uhlobo, kunye neenkcukacha zobugcisa ze-runner zibaluleke kakhulu ekumiseleni ukusebenza kakuhle kweturbine, uluhlu lwentloko yokusebenza, kunye neemeko zokusetyenziswa kwayo.

1. Uhlu lwee-Water Turbine Runners

Ii-water turbine runners zihlala zahlulwe zibe ziindidi ezintathu eziphambili ngokusekwe kuhlobo lokuhamba kwamanzi ezikusebenzisayo:

A. Abagijimi abanomdla

Iiturbine ze-impulse zisebenza ngeejethi zamanzi ezinesantya esiphezulu ezibetha iiblade ze-runner kuxinzelelo lomoya. Ezi turbine zenzelweintloko ephezulu, ukuhamba kancinciizicelo.

• Umdlali wePelton Runner:

  • Ulwakhiwo: Iibhakethi ezimile okwesipuni ezifakwe ecaleni kwevili.

  • Uluhlu lweNtloko: 100–1800 yeemitha.

  • Isantya: Isantya esiphantsi sokujikeleza; kudla ngokufuna ukonyusa isantya.

  • Izicelo: Iindawo zeentaba, umbane omncinci ongaphandle kwegridi.

B. Ababaleki bempendulo

Ii-turbine ze-reaction zisebenza ngoxinzelelo lwamanzi olutshintsha kancinci njengoko ludlula kwi-runner. Ezi run ziyantywiliselwa emanzini kwaye zisebenza phantsi koxinzelelo lwamanzi.

• UFrancis Runner:

  • Ulwakhiwo: Ukuhamba okuxutyiweyo kunye nentshukumo yangaphakathi yeradial kunye ne-axial.

  • Uluhlu lweNtloko: 20–300 yeemitha.

  • Ukusebenza kakuhle: Iphezulu, ngesiqhelo ingaphezulu kwe-90%.

  • Izicelo: Isetyenziswa kakhulu kwizikhululo zamanzi eziphakathi.

• Umqhubi weKaplan:

  • Ulwakhiwo: Isixhobo sokuhamba kwe-Axial esineeblade ezilungisekayo.

  • Uluhlu lweNtloko: 2–30 iimitha.

  • Iimbonakalo: Iiblade ezilungisekayo zivumela ukusebenza kakuhle xa kukho imithwalo eyahlukeneyo.

  • Izicelo: Imilambo esezantsi, egeleza kakhulu kunye nokusetyenziswa kwamaza.

• Umgijimi wePropeller:

  • Ulwakhiwo: Ifana neKaplan kodwa ineeblade ezizinzileyo.

  • Ukusebenza kakuhle: Ilungele kuphela xa kukho ukuhamba rhoqo.

  • Izicelo: Iindawo ezincinci zamanzi ezinomsinga ozinzileyo kunye nentloko ezinzileyo.

C. Ezinye iintlobo zabagijimi

• I-Turgo Runner:

  • Ulwakhiwo: Iijethi zamanzi zibetha imbaleki ngekona.

  • Uluhlu lweNtloko: 50–250 yeemitha.

  • Inzuzo: Isantya esiphezulu sokujikeleza kunePelton, ulwakhiwo olulula.

  • Izicelo: Izikhululo zamanzi ezincinci ukuya kweziphakathi.

• I-Cross-Flow Runner (iBanki-Michell Turbine):

  • Ulwakhiwo: Amanzi ahamba phakathi komdyarho ngokunqamlezayo, kabini.

  • Uluhlu lweNtloko: 2–100 yeemitha.

  • Iimbonakalo: Ilungele umbane omncinci wamanzi kunye nokuhamba kwamanzi okuguquguqukayo.

  • Izicelo: Iinkqubo ezingaphandle kwegridi, i-mini hydro.

2. Iinkcukacha eziphambili zobugcisa zabagijimi

Iindidi ezahlukeneyo zabagijimi zifuna ingqalelo enzulu kwiiparameter zabo zobugcisa ukuqinisekisa ukusebenza kakuhle:

3. Iikhrayitheriya zokukhetha

Xa ukhetha uhlobo lomgijimi, iinjineli kufuneka ziqwalasele oku kulandelayo:

• Intloko kunye nokuhamba: Igqiba ukuba ikhethe ukusabela okanye ithathe inyathelo.

• Iimeko Zesiza: Ukuguquguquka komlambo, umthwalo wentlabathi, utshintsho lwexesha lonyaka.

• Ukuguquguquka kokusebenza: Imfuneko yokulungiswa kweblade okanye ukulungiswa kwendlela ejikeleziswa ngayo.

• Iindleko kunye noLondolozo: Kulula kakhulu ukuzigcina iimbaleki ezilula ezifana nePelton okanye iPropeller.

4. Iindlela Eziza Kulandela

Ngenxa yokuqhubela phambili kwi-computational fluid dynamics (CFD) kunye nokuprinta ngesinyithi se-3D, uyilo lwe-turbine runner luya luguqukela kwezi zinto zilandelayo:

• Ukusebenza kakuhle okuphezulu kwimijelo eguquguqukayo

• Iimbaleki ezenzelwe wena kwiimeko ezithile zendawo

• Ukusetyenziswa kwezinto ezidityanisiweyo kwiiblade ezikhaphukhaphu nezimelana nokugqwala

Isiphelo

Izibambisi zeturbine zamanzi zisisiseko sokuguqulwa kwamandla ombane ngamanzi. Ngokukhetha uhlobo olufanelekileyo lwebambisi kunye nokwenza ngcono iiparameter zobugcisa, izityalo zamanzi zinokufikelela ekusebenzeni kakuhle, ixesha elide, kunye nefuthe elinciphileyo kwindalo esingqongileyo. Nokuba zezombane zasemaphandleni ezincinci okanye izityalo ezinkulu eziqhagamshelwe kwigridi, ibambisi ihlala isitshixo sokuvula amandla apheleleyo ombane wamanzi.
