Izigaba Zokukhiqiza Isethi Eyingozi

Ukudlidliza kwesethi ye-hydro-generator kuhlukile kulokho kwemishini evamile yamandla ngokwezinga elithile.Isenzakalo sokudlidliza kweyunithi sisobala, kodwa umthombo wokudlidliza uvame ukufihlwa.Ngaphezu kokudlidliza okubangelwa ingxenye ejikelezayo noma egxilile yomshini ngokwawo, umthelela wamandla kazibuthe kagesi nemishini kanye nengcindezi yokugeleza esebenza engxenyeni echichimayo ye-turbine ekudlidlizeni kwesistimu nezingxenye zayo kufanele kucatshangelwe. .Kunezizathu eziningi zokudlidliza kwesethi ye-hydro-generator, futhi imithombo eminingi yokudlidliza ivamise ukuba khona ngesikhathi esisodwa.Ngokuvamile kunenkolelo yokuthi imithombo yamandla okuphazamisayo edala ukudlidliza kweyunithi iphuma ikakhulukazi ezintweni ezithinta amanzi, umshini nezikagesi, ezisebenzisanayo futhi ezivame ukulukana ndawonye ukuze zenze ukudlidliza okuhambisanayo.

Ukudlidliza okuvamile kweyunithi ephehla ugesi ngamanzi ngeke kubangele ukulimala kubasebenzi, kodwa uma ukudlidliza kudlula amanani avumelekile, ikakhulukazi ukudlidliza nokuzwakala kwesikhathi eside, ikhwalithi yokuphakelwa kukagesi, impilo yesevisi yeyunithi, ukusebenza kwezisetshenziswa ezisizayo kanye izinsimbi, isisekelo seyunithi kanye nezakhiwo ezizungezile, futhi ngisho nazo zonke ziletha umonakalo omkhulu ekusebenzeni okuphephile nomnotho kwesiteshi sokuphehla ugesi ngamanzi.

Ukukhiqiza ukulimaza kwesethi kungahlukaniswa ngokwezigaba ezilandelayo:

Kuholela ekwakhekeni nasekunwebeni kwendawo yokulimala yokukhathala phakathi kwensimbi ne-weld, okuholela ekuqhekekeni, ngisho nokulimala kokuqhekeka kanye ne-scrap.

Ukukhulula ezinye izinsimbi zeyunithi ngeke nje kuholele ekuqhekekeni kwe-fasteners ngokwazo, kodwa futhi kukhulise ukudlidliza kwezingxenye zokuxhuma futhi kusheshise ukulimala kwazo.

Izinga lokuguga okuhambisanayo kwezingxenye ezijikelezayo zeyunithi esheshayo.I-shaft enkulu inyakaza ngobudlova, i-shaft kanye nezinga lokushisa elithwalayo liyakhuphuka, lithwala ukulahlekelwa ukuvutha;Ukudlidliza kwe-rotor ye-generator kukhulu kakhulu, khulisa izinga lokuguga lendandatho yokushelela kanye nebhulashi, khulisa izinga lokushisa, shisa isihlahla esithwalayo, andise inhlansi yebhulashi.

I-vortex pulsating pressure eyakhiwe ku-tailpipe izokwenza isistimu yokuchichima inyakaze, ukuphuma kokushwibeka kweyunithi, kanye nodonga lombhobho womsila uqhekeke.Ezimweni ezimbi kakhulu, yonke isevisi ye-tailpipe ingase yonakale.

Imiphumela ye-resonance ye-turbine yamanzi mibi kakhulu.Isibonelo, ukuduma phakathi kwemishini yeyunithi nesitshalo kungalimaza sonke isitshalo nesitshalo ngamazinga ahlukahlukene.

Ukudlidliza kweHydraulic ukudlidliza okubangelwa ukuphazamiseka kwengcindezi ye-hydrodynamic yengxenye ye-hydraulic ye-turbine, ebizwa ngokuthi i-hydraulic vibration.Izici ze-hydraulic ezibangela ukudlidliza ikakhulukazi zifaka: ukungazinzi kwe-hydraulic okubangelwa i-low-frequency vortex band ye-tailpipe, uhlelo lwe-karman vortex, i-blade vortex, ukungazinzi ohlelweni lokuguquka, ukungalingani kwe-hydraulic, i-cavitation ye-cavitation, i-jet clearance (i-axial flow turbine) njalo njalo.

I-low frequency vortex zone ku-tailpipe iwuhlobo lokugeleza okungazinzile kwe-tailpipe ye-Francis turbine kanye ne-axial distance turbine ngaphansi komthwalo oyingxenye.Lapho i-turbine isebenza ngaphansi kwesimo esingekho-design, i-pulsation yokucindezela ngokuvamile ivela ku-tailpipe ngenxa yethonya lokugeleza kwamanzi ajikelezayo, ukuchithwa kwe-vortex kanye ne-cavitation endaweni yokugijima.Ikakhulukazi ngemva kokuvela kwebhande elikhulu le-vortex ku-tailpipe, ibhande le-vortex lizungeza epayipini cishe ngezikhathi ezimisiwe, okubangela ukucindezela kwe-low-frequency pulsation yokugeleza kwamanzi.Lapho ukugeleza kwamanzi kwenzeka ku-tube, i-pulsation yokucindezela izobangela ukudlidliza kodonga lwepayipi lomsila, umgijimi, indlela yokuqondisa amanzi, ipayipi ye-volute ne-pressure.

Izinyathelo zokuvimbela nokwelashwa:

Lungiselela idizayini ye-hydraulic.I-airfoil ye-Angle runner eyinegethivu, idizayini enengqondo yomthetho wokusabalalisa ukuzungeza kwe-outlet, umqhele ofanelekile kanye nekhoni yokukhipha, kanye nomgijimi onama-axiliary blades kungacatshangelwa kumgijimi ogelezayo oxubile wekhanda eliphezulu.

Hlala kude nendawo yokusebenza yokudlidliza.Shintsha izinga lokugeleza nokujikeleza kokugeleza kwamanzi, njengokwelula ikhoni yokukhipha, ukukhulisa ingxenye yekhoni yomugqa omude, ukukhulisa i-engeli yekhoni yepayipi lomsila, ukukhulisa ipuleti le-baffle kanye nepuleti le-baffle, lawula ukugqama kwebhande le-vortex. , njll.

Ngesikhathi sokusebenza kweyunithi, ukunikezwa komoya okufanelekile kwenziwa endaweni yamanje ye-eddy, ngokuvamile ukunikezwa komoya wemvelo, noma ukunikezwa komoya okuphoqelelwe uma kunesidingo.

Izigaba ezingenhla zihlukaniswe yi-Dingbo Power, uma unombuzo mayelana ne amajeneretha edizili ,pls xhumana ne-Dingbo Power imikhiqizo yayo emboza i-Cummins, i-Perkins, i-Volvo, i-Yuchai, i-Shangchai, i-Deutz, Ricardo , MTU, Weichai njll.
