4) Kwamanye amaphrojekthi kagesi wamanzi, ukuhlolwa kwesici seyunithi ye-generator ye-turbine yamanzi nakho kuyenziwa.Ukuqinisekisa inani lesiqinisekiso sokusebenza kahle komkhiqizi nokuhlinzeka ngedatha yokusebenza kwezomnotho kwesikhungo sikagesi.
25. Iyini inhloso yokuhlolwa kwesivinini esiphezulu seyunithi?
Impendulo: 1) hlola ikhwalithi yokulawula yedivayisi yokulawula ezenzakalelayo yeyunithi;2) Qonda indawo yokudlidliza yeyunithi engaphansi komthwalo;3) Hlola futhi uqinisekise inani eliphakeme lokukhuphuka leyunithi yedatha elawulayo, inani eliphakeme lokucindezela kokucindezela phambi kwevane yomhlahlandlela kanye ne-coefficient yokulungisa umehluko wombusi;4) Qonda umthetho woshintsho wezimpawu zangaphakathi ze-hydraulic kanye nemishini yeyunithi kanye nomthelela wayo emsebenzini weyunithi, ukuze unikeze idatha edingekayo yokusebenza okuphephile kweyunithi;5) Khomba ukuzinza nokunye ukusebenza kombusi.
26. Indlela yokuhlola ibhalansi emile ye-hydraulic turbine?
Impendulo: beka ama-gauge amaleveli amabili kuzilinganisi ezimbili zika-X kanye no-Y iringi engezansi yomgijimi;Beka isisindo sebhalansi esinesisindo esifanayo nezinga elilinganayo ku-bisector - X kanye - y (isisindo saso singabalwa ngokufundwa kwezinga);Ngokwezinga lezinga, beka isisindo sebhalansi ohlangothini olukhanyayo kuze kube yilapho ibhamuza lezinga ligxilile, bese ubhala phansi usayizi P kanye ne-azimuth yesisindo sokugcina sebhalansi α.
27. Ungalikhipha kanjani i-thrust head ngesikhathi sokulungiswa?
Impendulo: susa isikulufu sokuxhuma phakathi kwe-thrust head kanye nepuleti lesibuko, ilengisa i-thrust head kumsele omkhulu ngentambo yensimbi bese uyiqinisa kancane.Phakamisa iphampu kawoyela, gxuma i-rotor, engeza amaphedi e-aluminium amane phakathi kwe-thrust head kanye nepuleti lesibuko endaweni eyi-90 degree, khipha uwoyela bese uwisa i-rotor.Ngale ndlela, i-shaft eyinhloko yehla nge-rotor, futhi inhloko ye-thrust ibanjwe yi-pad futhi ikhishwe kude.Phinda izikhathi eziningana, lawula ukushuba komcamelo phakathi kuka-6-10mm isikhathi ngasinye, futhi kancane kancane ukhiphe inhloko yokuphonsela kuze kube yilapho ikwazi ukuphakanyiswa ngehuku elikhulu.Ngemva kokukhipha izikhathi eziningana, ukubambisana phakathi kwekhanda eliphonswayo kanye ne-shaft enkulu kuyaxega, futhi i-thrust head ingakhishwa ngokuqondile nge-crane.28. Bheka ithebula elilandelayo ukuze uthole irekhodi eliguqukayo le-1# turbine (iyunithi: 0.01mm):
Bala ukushwibeka okugcwele kanye nokushwibeka kwenetha kwegayidi ye-hydraulic, inkomba engezansi negayidi ephezulu, bese uqedela ithebula elingenhla.
