Ubume kunye nesakhiwo sofakelo lwe-hydraulic turbine
Iseti yejenereyitha yeinjini yamanzi yintliziyo yenkqubo yamandla ombane wamanzi.Ukuzinza kunye nokukhuseleka kwayo kuya kuchaphazela uzinzo kunye nokhuseleko lwenkqubo yonke yamandla kunye nokuzinza kokunikezelwa kwamandla.Ngoko ke, kufuneka siqonde ukubunjwa kwesakhiwo kunye nesakhiwo sofakelo lwe-turbine yamanzi, ukwenzela ukuba ibe luncedo ekugcinweni okuqhelekileyo kunye nokulungiswa.Nantsi intshayelelo emfutshane yolwakhiwo lweinjini yomoya oqhutywa ngamanzi.
Ubume be turbine yehydraulic
Ijeneretha yeHydro yenziwe ngerotor, stator, isakhelo, ithrust bearing, isikhokelo sokuthwala, i-cooler, ibhuleki kunye nezinye izinto eziphambili;I-stator iqulunqwe kakhulu ngesakhelo, i-core core, i-winding kunye nezinye izinto;I-stator core yenziwe ngamacwecwe ensimbi ye-silicon epholile, enokuthi yenziwe ibe yinto edibeneyo kunye neyokwahlula ngokwemiqathango yokuvelisa kunye nokuthutha;Ijenereyitha yeinjini yomoya yamanzi ikholisa ukupholiswa ngumoya ovaliweyo ojikelezayo.Iyunithi yomthamo omkhulu kakhulu ithanda ukusebenzisa amanzi njengendawo yokupholisa ukupholisa ngqo i-stator.Ngexesha elifanayo, i-stator kunye ne-rotor ngamanzi aphindwe kabini iiyunithi zejeneretha ye-injini yokupholisa yangaphakathi.
Isakhiwo sokufakela i-hydraulic turbine
Ulwakhiwo lofakelo lwe-hydro generator ludla ngokumiselwa luhlobo lwe-hydraulic turbine.Kukho ikakhulu ezi ndidi zilandelayo:
1. Ulwakhiwo oluthe tye
Ijenereyitha ye hydraulic turbine enesakhiwo esithe tyaba idla ngokuqhutywa yiinjini ye-impulse.Iyunithi ye turbine yehydraulic ethe tyaba idla ngokuthatha iibheringi ezimbini okanye ezintathu.Isakhiwo seebheringi ezimbini sinobude obufutshane be-axial, isakhiwo esidibeneyo kunye nofakelo olufanelekileyo kunye nohlengahlengiso.Nangona kunjalo, xa isantya esibalulekileyo se-shafting singenako ukuhlangabezana neemfuno okanye umthwalo wokuthwala ukhulu, ukwakhiwa kwezintathu ezintathu kufuneka zamkelwe, Uninzi lweeyunithi zasekhaya ze-hydraulic generator generator ziyunithi ezincinci kunye nobukhulu obuphakathi, kunye neeyunithi ezinkulu ezinqamlekileyo ezinomthamo 12.5mw nazo ziveliswa.Iiyunithi ezithe tyaba zejenereyitha ye-hydraulic turbine turbine eziveliswa kumazwe angaphandle ezinomthamo we-60-70mw azinqabile, ngelixa iiyunithi ezithe tyaba zejenereyitha ye-hydraulic turbine enezikhululo zamandla ezimponthiweyo zineyunithi enye yomthamo wama-300MW;
2. Isakhiwo esithe nkqo
Iiyunithi zejenereyitha zamanzi asekhaya zisetyenziswa ngokubanzi kwisakhiwo esithe nkqo.Iiyunithi zejenereyitha zamanzi ezithe nkqo zidla ngokuqhutywa nguFrancis okanye i-axial-flow turbines.Ulwakhiwo oluthe nkqo lunokwahlulwa lube luhlobo olumisiweyo kunye nohlobo lwesambrela.I-thrust bearing ye-jenereyitha ebekwe kwindawo ephezulu ye-rotor ngokudibeneyo ebizwa ngokuba luhlobo olunqunyanyisiweyo, kwaye i-thrust bear ibekwe kwindawo engezantsi ye-rotor ngokudibeneyo ebizwa ngokuba luhlobo lwe-ambrela;
3. Ubume beTubula
Iyunithi yejenereyitha ye-tubular turbine iqhutywa yi-tubular turbine.I-tubular turbine luhlobo olukhethekileyo lwe-axial-flow turbine enamagqabi angatshintshiyo okanye ahlengahlengiswayo.Isici sayo esiphambili kukuba i-axis ye-runner ihlelwe ngokuthe tye okanye i-oblique kwaye ihambelana nesikhokelo sokuhamba kwe-inlet kunye nokuphuma kwemibhobho ye-turbine.Ijeneretha ye-tubular turbine inenzuzo yesakhiwo esincinci kunye nobunzima obulula, Isetyenziswa ngokubanzi kwizikhululo zamandla ezinentloko yamanzi aphantsi.
Ezi zakhiwo zofakelo kunye nohlobo lofakelo lwesakhiwo se-hydraulic turbine.Iseti yejenereyitha yeinjini yamanzi yintliziyo yamandla yesikhululo sombane wamanzi.Uhlengahlengiso oluqhelekileyo kunye nokugcinwa kuya kwenziwa ngokuhambelana nemigaqo nemigaqo.Kwimeko yokusebenza okungaqhelekanga okanye ukusilela, kufuneka sihlalutye ngokwenzululwazi nangengqiqo kwaye siyile iskimu sokulondoloza ukuphepha ilahleko enkulu.
