Umphumela we-hydro-generator uyehla
Isizathu
Endabeni yekhanda lamanzi elingaguquki, lapho ukuvulwa kwe-vane ye-guide sekufinyelele ekuvuleni okungalayishiwe, kodwa i-turbine ayikafinyeleli isivinini esilinganiselwe, noma lapho ukuphuma okufanayo, ukuvulwa kwe-vane ye-guide kukhulu kunokuqala, kuyabhekwa. ukuthi ukuphuma kweyunithi kwehlile.Izizathu ezinkulu zokwehla komkhiqizo yilezi: 1. Ukulahleka kokugeleza kwe-turbine yamanzi;2. Ukulahlekelwa ukongiwa kwamanzi kwenjini yamanzi;3. Ukulahlekelwa ngumshini we-turbine yamanzi.
Iyacubungula
1. Uma iyunithi isebenza noma ivala, qinisekisa ukuthi ukujula kokucwiliswa kweshubhu okusalungiswa akukho ngaphansi kuka-300mm (ngaphandle kwe-turbine yomthelela).2. Naka ukungena kwamanzi noma ukuphuma ukuze ugcine ukugeleza kwamanzi ngokulingana futhi kungavinjwa.3. Gcina umgijimi egijima ngendlela evamile, futhi umise umshini ukuze uhlolwe uma kunomsindo.4. Kuma-axial-flow fixed-blade turbines, uma okukhiphayo kweyunithi kwehla ngokuzumayo futhi nokudlidliza kwanda, kufanele ivalwe ngokushesha ukuze ihlolwe.
Izinga lokushisa lesihlahla esithwalayo leyunithi likhuphuka kakhulu
Isizathu
Kunezinhlobo ezimbili zama-turbine bearings: i-guide bear kanye ne-thrust bear.Izimo zokuqinisekisa ukusebenza okuvamile kwe- bearing ukufakwa okulungile, ukugcotshwa okuhle kanye nokunikezwa okujwayelekile kwamanzi okupholisa.Ngokuvamile kunezindlela ezintathu zokugcoba: ukugcoba ngamanzi, ukugcotshwa kwamafutha amancane kanye nokuthambisa okomile.Izizathu zokukhuphuka okubukhali kokushisa kwe-shaft yilezi: okokuqala, ikhwalithi yokufaka i-bearing empofu noma ukugqokwa kokuthwala;okwesibili, ukwehluleka kohlelo lwamafutha okugcoba;okwesithathu, ilebula yamafutha okugcoba engahambisani noma izinga likawoyela eliphansi;okwesine, ukwehluleka kohlelo lwamanzi okupholisa;okwesihlanu, ngenxa yesizathu esithile Yenza iyunithi idlidlize;Okwesithupha, ukuvuza kwamafutha okuzala futhi izinga likawoyela liphansi kakhulu.
Iyacubungula
1. Ama-bearings agcotshwe ngamanzi.Amanzi okugcoba kufanele ahlungwe ngokuqinile ukuze kuqinisekiswe ikhwalithi yamanzi.Amanzi akufanele aqukathe inani elikhulu lesihlabathi namafutha ukuze kuncishiswe ukugqoka kokuthwala nokuguga kwerabha.
2. Amabheringi agcotshisiwe kawoyela azacile ngokuvamile asebenzisa ukuzihambisa, ukusebenzisa i-slinger kawoyela ne-thrust plate, futhi uwoyela ozijikelezayo uhlinzekwa ngokuzungezisa kweyunithi.Qaphela kakhulu izimo zokusebenza zendandatho ye-slinger.Iringi ye-slinger ayivunyelwe ukuthi ibambeke, ukunikezwa kukaphethiloli ku-thrust plate kanye nezinga likawoyela lethangi likaphethiloli.
3. Gcoba ama-bearings ngamafutha omile.Naka ukuthi ukucaciswa kwamafutha omile kuyahambisana yini namafutha athwalayo, nokuthi izinga likawoyela lihle yini, engeza uwoyela njalo ukuze uqinisekise ukuthi imvume yokuthela ingu-1/3 ~ 2/5.
4. Idivaysi yokuvala ipayipi lamanzi elithwalayo kanye nokupholisa liqinile ukuvimbela amanzi okucindezela nothuli ekungeneni kwe-bearing futhi abhubhise ukuthambisa okuvamile kwe-bearing.
5. Ukuvunyelwa kokufakwa kwe-bearing egcotshiwe kuhlobene nokucindezela kweyunithi yesihlahla esithwalayo, isivinini esiqondile sokujikeleza, indlela yokugcoba, i-viscosity yamafutha, ukucutshungulwa kwezingxenye, ukunemba kokufaka kanye ne-Baidu ye ukudlidliza kweyunithi.
Ukudlidliza kweyunithi
(1) Ukudlidliza komshini, ukudlidliza okubangelwa izizathu zemishini.
Izizathu: Okokuqala, i-hydraulic turbine inzima kakhulu;okwesibili, i-axis ye-turbine kanye nejeneretha ayilungile, futhi ukuxhumana akukuhle;okwesithathu, ukuthwala akulungile noma ukulungiswa kwegebe akulungile, ikakhulukazi igebe likhulu kakhulu;okwesine, kukhona ukungqubuzana phakathi kwezingxenye ezijikelezayo nezingxenye ezimile.ukungqubuzana
(2) Ukudlidliza kwe-hydraulic, ukudlidliza kweyunithi okubangelwa ukulahlekelwa ibhalansi yamanzi ageleza kumgijimi.
Izizathu: Esinye siwukuthi i-vane yomhlahlandlela iphula i-bolt futhi ihlephuka, okwenza ukuvuleka kwe-vane yomhlahlandlela kuhluke, ukuze ukugeleza kwamanzi azungeze umgijimi kungalingani;enye iwukuthi kukhona udoti ku-volute noma umgijimi uminyene, okubangela ukuthi ageleze kumgijimi.Ukugeleza kwamanzi nxazonke akulingani;okwesithathu, ukugeleza kwamanzi kushubhu esalungiswa akuzinzile, okubangela ukuthi umfutho wamanzi weshubhu esalungiswa uguquke ngezikhathi ezithile, noma umoya ungena kuvolute ye-turbine, okubangela ukudlidliza kweyunithi nokubhonga kokugeleza kwamanzi.
(3) Ukudlidliza kogesi, ukudlidliza kweyunithi okubangelwa ukulahlekelwa ibhalansi noma ukushintsha kwenani likagesi kungazelelwe.
Izizathu: Esinye ukungalingani okukhulu kwamandla wesigaba sesithathu sejeneretha, okubangela ukungalingani kwamandla kazibuthe wezigaba ezintathu;enye iwushintsho olusheshayo lomsinga okubangelwa ingozi kagesi, okubangela ukuthi ijeneretha ne-turbine zingakwazi ukuvumelanisa isivinini sazo ngaso leso sikhathi.;Okwesithathu, igebe phakathi kwe-stator ne-rotor alifani, okubangela ukungazinzi kwensimu yamagnetic ejikelezayo.
(4) Ukudlidliza kwe-Cavitation, ukudlidliza kweyunithi okubangelwa i-cavitation.
Izizathu: Okokuqala, ukudlidliza okubangelwa ukungalingani kwe-hydraulic, i-amplitude eyanda ngokunyuka kokugeleza;okwesibili ukudlidliza okubangelwa ukungalingani okubangelwa ubunzima bomgijimi, ukuxhumeka okungalungile kweyunithi, kanye ne-eccentricity, i-amplitude ekhuphuka ngokunyuka kwejubane.;Okwesithathu ukudlidliza okubangelwa indawo kagesi, i-amplitude iyanda ngokukhula kwe-excitation current, futhi ukudlidliza kunganyamalala lapho ukukhishwa kukhishwa;okwesine ukudlidliza okubangelwa i-cavitation, ukuphakama kwayo kuhlobene nendawo yomthwalo, ngezinye izikhathi iphazamiseka, ngezinye izikhathi inzima, Ngesikhathi esifanayo, umsindo oshayayo ukhiqizwa ku-tube yokusalungiswa, futhi kungase kube khona into eguqukayo ku-vacuum. igeji.
Ukushisa kwesihlahla esithwalayo seyunithi kuyanda noma kuphezulu kakhulu
Isizathu
1. Izizathu zokugcinwa nokufakwa: ukuvuza komcengezi kawoyela, indawo yokufaka engalungile yepayipi lepayipi, igebe lamathayela elingathobeli, ukudlidliza okungavamile kweyunithi okubangelwa izinga lokufakwa, njll.;
2. Izizathu zokusebenza: ukusebenza endaweni yokudlidliza, ukwenganyelwa kwezinga likawoyela othwele okungavamile nezinga likawoyela, ukwehluleka ukugcwalisa uwoyela ngesikhathi, ukuphazanyiswa kwamanzi okupholisa, ukwengamela ukushoda kwamanzi, kanye nokusebenza kweyunithi yesikhathi eside ngesivinini esiphansi.
Iyacubungula
1. Uma izinga lokushisa le-tile likhuphuka, qala uhlole amafutha okugcoba, engeza amafutha ngesikhathi noma uthinte ukushintsha amafutha;lungisa umfutho wamanzi okupholisa noma ushintshe imodi yokuphakela amanzi;hlola ukuthi ingabe ukudlidliza kweyunithi kuyaweqa yini izinga futhi kumise ukudlidliza uma ukudlidliza kungenakuqedwa;
2. Uma izinga lokushisa livikela indawo yokuphuma, kufanele iqashwe futhi ivalwe ngokujwayelekile, futhi uhlole ukuthi isihlahla esithwalayo sishile yini.Uma isihlahla esithwalayo sesishisiwe, kufanele sishintshwe kufakwe ithayela elisha noma siklwelwe kabusha.
Okwesihlanu, ukwehluleka kokulawula isivinini
Lapho ukuvulwa kombusi kuvalwe ngokugcwele, umgijimi akakwazi ukuma kuze kube yilapho ukuvulwa kwe-vane ye-guide kungakwazi ukulawulwa ngempumelelo.Lesi simo sibizwa nge-speed control failure.Izizathu: Okokuqala, uxhumano lwe-vane ye-guide igobile, futhi ukuvulwa kwe-vane ye-guide ayikwazi ukulawulwa ngempumelelo, okubangela ukuthi i-vane yomhlahlandlela ivalwe futhi iyunithi ayikwazi ukumiswa.Kumele kuqashelwe ukuthi amanye amayunithi amancane awanayo idivayisi ye-brake, futhi iyunithi ayikwazi ukumiswa okwesikhashana ngaphansi kwesenzo se-inertia.Ngalesi sikhathi, ungalenzi iphutha ngokuthi ivaliwe.Uma uqhubeka nokuvala ama-vanes omhlahlandlela, induku yokuxhuma izogoba.Okwesibili wukuthi i-speed control ihluleka ngenxa yokuhluleka kwe-automatic speed governor.Uma iyunithi ye-hydraulic turbine isebenza ngendlela engavamile, ikakhulukazi uma iyunithi isesimweni esibucayi sokusebenza okuphephile, kufanele izame ngokushesha ukuvala futhi ibhekane nayo.Ukusebenza ngokungabaza kuzokhulisa ukwehluleka kuphela.Uma umbusi ehluleka futhi indlela yokuvula i-vane yegayidi ayikwazi ukumiswa, i-valve eyinhloko ye-turbine kufanele isetshenziselwe ukunqamula ukugeleza kwamanzi ku-turbine.
Ezinye izindlela zokwelapha: 1. Hlanza njalo imfucumfucu endleleni eqondisa amanzi, igcine ihlanzekile, futhi ugcwalise izingxenye ezihambayo njalo;2. Ichweba lamanzi okungena kulo kumele lifakwe ama-rack kadoti futhi licoshwe njalo;3. Ama-turbines anoma yikuphi ukufakwa kwemoto kufanele ashintshwe ngesikhathi sama-Brake pads, engeza uketshezi lwamabhuleki.
