Ijeneretha ye-Hydro iyinhliziyo yesiteshi samandla kagesi.Iyunithi ye-generator ye-turbine yamanzi iyisisetshenziswa esibaluleke kakhulu sesikhungo sokuphehla amandla ngamanzi.Ukusebenza kwayo okuphephile kuyisiqinisekiso esiyisisekelo sesikhungo sokuphehla ugesi ngamanzi ukuze kuqinisekiswe ukuphehlwa nokuphakelwa kukagesi okuphephile, okuseqophelweni eliphezulu futhi kwezomnotho, okuhlobene ngokuqondile nokusebenza okuphephile nokuzinzile kwegridi yamandla.Indawo yokusebenza yeyunithi ye-generator ye-turbine yamanzi ihlobene nempilo nempilo yesevisi yeyunithi ye-generator.Nazi izinyathelo ezithathiwe ukuthuthukisa indawo yokusebenza kwejeneretha ngokusekelwe ku-Xiaowan Hydropower Station.
Ukwelashwa kwe-oil rejection ye-thrust oil tank
Ukwenqatshwa kukawoyela kwe-thrust bear kuzongcolisa ijeneretha ye-hydro kanye nempahla yayo eyisiza.Iyunithi ye-Xiaowan nayo ihlaselwe ukunqatshwa kukawoyela ngenxa yejubane layo eliphezulu.Ukwenqatshwa kukawoyela kwe-Xiaowan thrust bear kubangelwa izizathu ezintathu: ukunwabuka kukawoyela kwebhawodi elixhumayo phakathi kwekhanda lokuphonseka kanye nomzimba wesikhungo se-rotor, ukunwabuka kukawoyela kwesembozo sokuvala esingaphezulu sesitsha sikawoyela, kanye nokuhlakazeka “ t” vala phakathi kwesigxivizo esihlanganisiwe sesitsha sikawoyela we-thrust kanye nophawu olungezansi lwe-annular.
Isikhungo sikagesi sicubungule imisele yokuvala endaweni ehlangene phakathi kwekhanda le-thrust kanye ne-rotor center body, yafaka imichilo yenjoloba engamelana nowoyela engu-8, yavala izimbobo zamaphini emzimbeni wesikhungo se-rotor, yashintsha ipuleti lokuqala elingaphezulu lekhava lesitsha sikawoyela ipuleti lekhava yegroove elithintanayo elinomugqa wokuvala wokulandelela, bese ifaka isivalo endaweni egcwele yokuxhumana yejoyinti elihlukanisiwe lesitsha sikawoyela ophonsayo.Njengamanje, into yokuphonsa uwoyela we-thrust oil groove isixazululwe ngempumelelo.
Ukuguqulwa kwe-Dehumidification kumhubhe womoya we-generator
Ukufiphala kwamazolo emhubheni womoya we-generator we-powerhouse engaphansi komhlaba eNingizimu China kuyinkinga evamile futhi enzima ukuyixazulula, enomthelela oqondile ekufakweni kwe-generator stator, i-rotor kanye nemishini yayo eyisizayo.U-Xiaowan uzothatha izinyathelo zokuqinisekisa ukuvaleka okuthembekile phakathi komhubhe womoya wejeneretha nangaphandle, futhi wengeze ukujiya kokujiya kuwo wonke amapayipi amanzi emhubheni womoya wejeneretha.
I-dehumidifier enamandla aphansi yasekuqaleni iguqulelwa ekubeni i-dehumidifier enamandla amakhulu evalwe ngokugcwele.Ngemuva kokuvala shaqa, umswakama emhubheni womoya wejeneretha ungalawulwa ngempumelelo ngaphansi kwama-60%.Akukho ukufingqa emshinini wokupholisa umoya wejeneretha kanye namapayipi esistimu yamanzi emhubheni womoya, okuvimbela ngempumelelo ukugqwala kwe-generator stator core kanye nomswakama wezinto ezisetshenziswayo zikagesi ezifanele kanye nezingxenye, futhi kuqinisekisa ukusebenza okuvamile kwejeneretha.
Ukuguqulwa kwenqama yebhuleki
Uthuli olukhiqizwe inqama ngesikhathi sokubhuleka i-generator wumthombo omkhulu wokungcola obangela ukungcoliswa kwe-stator kanye ne-rotor.I-Xiaowan Hydropower Station ithathe indawo yenqama yebhuleki yokuqala yafaka inqama engenathuli ye-asbestos engenalo insimbi.Njengamanje, alukho uthuli olusobala ngesikhathi sokubhuleka kwe-generator, futhi umphumela wokuthuthuka uyabonakala.
Lezi yizinyathelo ezithathwe i-Xiaowan Hydropower Station ukuthuthukisa nokwenza ngcono indawo yokusebenza kwamajeneretha.Ekhulwini leminyaka ukuthuthukiswa nokwenza ngcono isimo sokusebenza kwesiteshi sikagesi, kufanele siklame ngokwesayensi nangokunengqondo uhlelo lokuthuthukisa ngokuya ngesimo sangempela esiqondile, esingeke senziwe jikelele.
