Isiphumo se-hydro-generator siyehla
Isizathu
Kwimeko yentloko yamanzi engaguqukiyo, xa isikhokelo sokuvula i-vane sifikelele ekuvulekeni kokungabikho komthwalo, kodwa i-turbine ayifikanga kwisantya esilinganiselweyo, okanye xa isiphumo esifanayo, ukuvulwa kwe-vane yesikhokelo kukhulu kunokuqala, kuyaqwalaselwa. ukuba imveliso yeyunithi yehlile.Ezona zizathu ziphambili zokuhla kwemveliso zezi: 1. Ukulahleka kokuhamba kweinjini yamanzi;2. Ilahleko yolondolozo lwamanzi kwiinjini yokuhambisa amanzi;3. Ukulahlekelwa ngumatshini weinjini yamanzi.
Iyaqhuba
1. Xa iyunithi isebenza okanye ivala, qinisekisa ukuba ubunzulu bobunzulu bobunzulu bobunzulu betyhubhu ayikho ngaphantsi kwe-300mm (ngaphandle kwe-turbine yempembelelo).2. Nika ingqalelo ekuphumeni kwamanzi okanye ukuphuma kwamanzi ukugcina ukuhamba kwamanzi ngokulinganayo kwaye kungaphazamiseki.3. Gcina umgijimi ebaleka kwindawo eqhelekileyo, kwaye umise umatshini ukuze ahlolwe ukuba kukho ingxolo.4. Kwi-axial-flow fixed-blade turbines, ukuba imveliso yeyunithi yehla ngokukhawuleza kwaye i-vibration iyanda, kufuneka ivalwe ngokukhawuleza ukuze ihlolwe.
Ukushisa kwesihlahla esithwala iyunithi kuphakama ngokukhawuleza
Isizathu
Kukho iindidi ezimbini zeebheringi zeinjini yomoya: ukuthwala okukhokelayo kunye nokuthwala i-thrust.Iimeko zokuqinisekisa ukusebenza okuqhelekileyo kokuthwala kufakelo oluchanekileyo, ukuthambisa okulungileyo kunye nokubonelelwa okuqhelekileyo kwamanzi okupholisa.Ngokuqhelekileyo kukho iindlela ezintathu zokuthambisa: ukuthambisa amanzi, ukuthambisa ioli encinci kunye nokuthambisa okomileyo.Izizathu zokunyuka okubukhali kwiqondo lokushisa kwe-shaft zi: okokuqala, umgangatho wofakelo olubi okanye ukunxiba;okwesibini, ukusilela kwenkqubo yeoli yokuthambisa;okwesithathu, ileyibhile yeoli yokuthambisa engahambelaniyo okanye umgangatho ombi we-oyile;okwesine, ukusilela kwenkqubo yamanzi okupholisa;okwesihlanu, ngenxa yesizathu esithile Yenza iyunithi ingcangcazele;Okwesithandathu, ukuvuza kweoli ethweleyo kwaye inqanaba leoli liphantsi kakhulu.
Iyaqhuba
1. Iibheringi ezithanjiswa ngamanzi.Amanzi okuthambisa kufuneka ahluzwe ngokungqongqo ukuqinisekisa umgangatho wamanzi.Amanzi akufanele aqulathe isixa esikhulu sesanti kunye neoli yokunciphisa ukuthwala ukuthwala kunye nokuguga kwerabha.
2. Iibheringi ezigcotyiweyo ze-oyile zithatha i-self-circulation, zithatha i-oyile slinger kunye ne-thrust plate, kunye ne-oyile ejikelezayo inikezelwa ngokujikeleza kweyunithi.Nika ingqalelo ngokucokisekileyo iimeko zokusebenza zeringi ye-slinger.Iringi ye-slinger ayivumelekanga ukuba ixinge, ukunikezelwa kwamafutha kwi-thrust plate kunye nenqanaba le-oyile yetanki yamafutha.
3. Lubricate iibheringi ngeoli eyomileyo.Nikelani ingqalelo ukuba ngaba iinkcukacha zeoli eyomileyo zihambelana neoli yokuthwala, kwaye ingaba umgangatho weoli ulungile, yongeza ioli rhoqo ukuze uqinisekise ukuba i-bearing clearance yi-1/3 ~ 2/5.
4. Isixhobo sokutywinwa sombhobho wamanzi wokuthwala kunye nokupholisa sichanekile ukukhusela amanzi oxinzelelo kunye nothuli ekungeneni kwi-bearing and kutshabalalisa i-lubrication eqhelekileyo yokuthwala.
5. Ukukhutshwa kokufakwa kwe-lubricated bearing ihambelana noxinzelelo lweyunithi yetyholo lokuthwala, isantya somgca wokujikeleza, indlela yokuthambisa, i-viscosity yeoli, ukucutshungulwa kwamacandelo, ukuchaneka kofakelo kunye ne-Baidu ye-oyile. ukungcangcazela kweyunithi.
Ukungcangcazela kweyunithi
(1) Ukungcangcazela komatshini, ukungcangcazela okubangelwa zizizathu zoomatshini.
Izizathu: Okokuqala, i-hydraulic turbine inzima kakhulu;okwesibini, i-axis ye-injini yomoya kunye nejenereyitha ayilungile, kwaye uqhagamshelwano alulunganga;okwesithathu, ukuthwala kunesiphene okanye uhlengahlengiso lomsantsa alufanelekanga, ngakumbi umsantsa mkhulu kakhulu;okwesine, kukho ukungqubana phakathi kwamalungu ajikelezayo kunye namalungu amileyo.ukungqubana
(2) I-hydraulic vibration, i-vibration yeyunithi ebangelwa ukulahlekelwa kwebhalansi yamanzi ageleza kumgijimi.
Izizathu: Esinye sesokuba i-vane yesikhokelo iphula ibholiti kwaye iphule, eyenza ukuvuleka kwe-vane yesikhokelo kuhluke, ukwenzela ukuba ukuhamba kwamanzi okujikeleze umgijimi kungalingani;enye kukuba kukho inkunkuma kwi-volute okanye imbaleki ixinile, ibangela ukuba impompoze kumbaleki.Amanzi ajikelezayo akalingani;okwesithathu, ukuhamba kwamanzi kwi-tube yedrafti ayizinzile, okubangela ukuba uxinzelelo lwamanzi lwetyhubhu yedrafti lutshintshe ngamaxesha, okanye umoya ungena kwi-volute ye-turbine, ebangela ukungcangcazela kweyunithi kunye nokugquma kwamanzi.
(3) Ukungcangcazela kombane, ukungcangcazela kweyunithi okubangelwa ukulahleka kwebhalansi okanye ukutshintsha ngokukhawuleza kobuninzi bombane.
Izizathu: Enye ukungalingani okunzulu kwesigaba sesithathu samanje sejenereyitha, ebangela ukungalingani kwamandla ombane wesigaba sesithathu;enye lutshintsho olukhawulezileyo lwangoku olubangelwa yingozi yombane, nto leyo ebangela ukuba ijenereyitha kunye ne turbine zingakwazi ukulungelelanisa isantya sazo ngoko nangoko.;Okwesithathu, i-gap phakathi kwe-stator kunye ne-rotor ayifani, ibangela ukungazinzi kwendawo yamagnetic ejikelezayo.
(4) I-vibration ye-Cavitation, i-vibration yeyunithi ebangelwa yi-cavitation.
Izizathu: Okokuqala, ukunyakaza okubangelwa ukungalingani kwe-hydraulic, i-amplitude eyonyuka ngokunyuka kokuhamba;okwesibini kukungcangcazela okubangelwa ukungalingani okubangelwa ubunzima bomgijimi, uxhulumaniso olubi lweyunithi, kunye ne-eccentricity, i-amplitude eyonyuka ngokunyuka kwesantya.;Okwesithathu kukushukuma okubangelwa ngumbane wombane, i-amplitude iyanda ngokunyuka kwe-excitation current, kwaye i-vibration inganyamalala xa i-excitation isusiwe;okwesine kukungcangcazela okubangelwa yi-cavitation, i-amplitude yayo inxulumene nommandla womthwalo, ngamanye amaxesha uphazamiseka, ngamanye amaxesha unzima, Kwangaxeshanye, ingxolo yokunkqonkqoza yenziwa kwidrafti yetyhubhu, kwaye kunokubakho isenzeko sojingi kwivacuum. igeyiji.
Ubushushu besihlahla esithwalayo seyunithi sanda okanye siphezulu kakhulu
Isizathu
1. Izizathu zokugcinwa kunye nokufakwa: ukuvuza kwe-oyile ye-oyile, indawo yokufakela engafanelekanga ye-tube yepayipi, i-gap ye-tile engahambelaniyo, i-vibration engaqhelekanga yeyunithi ebangelwa umgangatho wofakelo, njl.;
2. Izizathu zokusebenza: ukusebenza kwindawo ye-vibration, ukubeka iliso ngokungaqhelekanga komgangatho we-oyile kunye nenqanaba leoli, ukungaphumeleli ukuzalisa ioli ngexesha elifanelekileyo, ukuphazamiseka kwamanzi okupholisa, ukubeka iliso lokunqongophala kwamanzi, kunye nokusebenza kwexesha elide eliphantsi kweyunithi.
Iyaqhuba
1. Xa ukushisa kwe-tile kuphakama, jonga kuqala ioli yokuthambisa, yongeza ioli ngexesha okanye udibanise ukutshintsha ioli;lungisa uxinzelelo lwamanzi okupholisa okanye utshintshe indlela yokubonelela ngamanzi;vavanya ukuba i-vibration yeyunithi igqithise umgangatho kwaye imise ukungcangcazela ukuba ukungcangcazela akukwazi ukupheliswa;
2. Ukuba iqondo lokushisa likhusela i-outlet, kufuneka libekwe iliso kwaye livale ngokuqhelekileyo, kwaye ukhangele ukuba i-bearing bush itshiswa.Emva kokuba isihlahla esithwalayo sitshisiwe, kufuneka sitshintshwe nge-tile entsha okanye ihlanjwe kwakhona.
Isihlanu, ukusilela kolawulo lwesantya
Xa uvulo lwerhuluneli luvalwe ngokupheleleyo, imbaleki ayinakuyeka de kube indawo yokuvula isikhokelo ayinakulawulwa ngokufanelekileyo.Le meko ibizwa ngokuba kukusilela kolawulo lwesantya.Izizathu: Okokuqala, udibaniso lwe-vane yesikhokelo lugobile, kwaye i-vane yesikhokelo ayinakulawulwa ngokufanelekileyo, ibangela ukuba i-vane yesikhokelo ivale kwaye iyunithi ayinakuyekwa.Kufuneka kuqatshelwe ukuba ezinye iiyunithi ezincinci azikho isixhobo sokuqhawula, kwaye iyunithi ayikwazi ukumiswa ixesha elithile phantsi kwesenzo se-inertia.Ngeli xesha, musa ukwenza impazamo ukuba ivaliwe.Ukuba uqhubeka nokuvala i-vanes yesikhokelo, intonga yokudibanisa iya kugoba.Okwesibini kukuba ulawulo lwesantya aluphumeleli ngenxa yokungaphumeleli kwerhuluneli yesantya esizenzekelayo.Xa iyunithi yeijini ye-hydraulic isebenza ngokungaqhelekanga, ngakumbi xa iyunithi ikwintlekele yokusebenza ngokukhuselekileyo, kufuneka ngokukhawuleza izame ukuyivala kwaye ijongane nayo.Umsebenzi othandabuzayo uya kukhulisa ukusilela kuphela.Ukuba irhuluneli ayiphumelelanga kwaye isixhobo sokuvula esikhokelayo asinakuyekwa, ivalve engundoqo yeinjini yomoya kufuneka isetyenziswe ukunqumla ukuhamba kwamanzi kwiinjini yomoya.
Ezinye iindlela zonyango: 1. Ukucoca rhoqo i-debris kwindlela yokukhokela amanzi, yigcine icocekile, kwaye ugcwalise iindawo ezihambayo rhoqo;2. Izibuko lamanzi angenayo kufuneka lixhotyiswe ngeerakhi zenkunkuma kwaye zicocwe rhoqo;3. Iiiturbines zalo naluphi na ufakelo lwesithuthi kufuneka zitshintshwe kwangethuba iiBrake pads, zongeze i-brake fluid.
