Ukwehla kwemveliso ye-hydro generator
(1) Unobangela
Ngaphantsi kwemeko yentloko yamanzi rhoqo, xa isikhokelo sokuvula i-vane sifikelele ekuvuleni okungalayishwanga, kodwa i-turbine ayifikeleli kwisantya esilinganiselweyo, okanye xa ukuvulwa kwe-vane yesikhokelo kukhulu kuneyokuqala kwimveliso efanayo, iyaqwalaselwa. ukuba imveliso yeyunithi iyancipha.Ezona zizathu ziphambili zokuhla kwemveliso zezi zilandelayo: 1. Ilahleko equkuqelayo ye-hydraulic turbine;2. Ukulahleka kwe-hydraulic ye-hydraulic turbine;3. Ukulahleka koomatshini kwi-injini ye-hydraulic.
(2) Isibambo
1. Ngaphantsi komqathango wokusebenza kweyunithi okanye ukuvala, ubunzulu obunzulu betyhubhu yedrafti abuyi kuba ngaphantsi kwe-300mm (ngaphandle kwe-impulse turbine).2. Nika ingqalelo ekungeneni kwamanzi okanye ekuphumeni kwawo ukugcina ukuhamba kwamanzi kulinganiswe kwaye kungaphazamiseki.3. Gcina umgijimi eqhuba phantsi kweemeko eziqhelekileyo kwaye uvale ukuze uhlolwe kunye nonyango kwimeko yengxolo.4. Kwi-axial flow blade blade turbine, ukuba imveliso yeyunithi yehla ngesiquphe kwaye ushukumo lomelele, iya kuvalwa ngoko nangoko ukuze ihlolwe.
I-2,Iyunithi ethwele iqondo lobushushu liyenyuka ngokukhawuleza
(1) Unobangela
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.Iindlela zokuthambisa zidla ngokubandakanya ukuthambisa kwamanzi, ukuthambisa kweoli ebhityileyo kunye nokuthambisa okomileyo.Izizathu zokunyuka okubukhali kokushisa kwe-shaft zimi ngolu hlobo lulandelayo: okokuqala, umgangatho wokufakela ukuthwala umpofu okanye ukuthwala kugugile;Okwesibini, ukusilela kwenkqubo yeoli yokuthambisa;Okwesithathu, ileyibhile yeoli yokuthambisa ayihambelani okanye umgangatho weoyile uhlwempuzekile;Okwesine, ukusilela kwenkqubo yamanzi okupholisa;Okwesihlanu, iyunithi iyangcangcazela ngenxa yesizathu esithile;Okwesithandathu, inqanaba le-oyile yokuthwala liphantsi kakhulu ngenxa yokuvuza kweoli.
(2) Isibambo
1. Kwiibheringi ezigcotyiweyo zamanzi, amanzi okuthambisa aya kucocwa ngokungqongqo ukuqinisekisa umgangatho wamanzi.Amanzi akayi kuqulatha inani elikhulu le-sediment kunye neoli yezinto zokunciphisa ukuguga kweebheringi kunye nokuguga kwerabha.
2. Iibheringi ezigcotyiweyo ze-oyile ezibhityileyo ngokuqhelekileyo zithatha i-self-circulation, kunye ne-oyile slinger kunye ne-thrust disc.Zijikeleziswa yiyunithi kwaye zibonelelwe ngeoyile ngokuzijikelezisa.Nika ingqalelo ngokukhawuleza imeko yokusebenza ye-oyile slinger.Isilingi seoli asiyi kubanjwa.Unikezelo lwe-oyile kwi-thrust disc kunye nenqanaba le-oyile yetanki yeoli yeposi iya kuba kumgangatho.
3. Lubricate ukuthwala ngeoli eyomileyo.Nika ingqalelo ukuba ngaba ukucaciswa kweoyile eyomileyo kuyahambelana neoyile yokuthwala kunye nokuba umgangatho weoyile ulungile.Yongeza i-oyile rhoqo ukuze uqinisekise ukuba indawo yokucima i-1 / 3 ~ 2 / 5.
4. Isixhobo sokutywina sokuthwala kunye nombhobho wamanzi okupholisa uya kuba ukhuselekile ukukhusela amanzi oxinzelelo kunye nothuli ekungeneni kwi-bearing kunye nokonakalisa i-lubrication yesiqhelo yokuthwala.
5. Ukukhutshwa kokufakwa kwe-lubricating bearing kuhambelana noxinzelelo lweyunithi, isantya somgca wokujikeleza, imowudi yokuthambisa, i-oil viscosity, ukucutshungulwa kwecandelo, ukuchaneka kofakelo kunye nokungcangcazela kweyunithi.
3, Ukungcangcazela kweyunithi
(1) Ukungcangcazela komatshini, ukungcangcazela okubangelwa zizizathu zoomatshini.
isizathu;Okokuqala, i-injini ye-hydraulic ithatha icala;Okwesibini, i-axis center ye-injini yamanzi kunye nejenereyitha ayichanekanga kwaye uxhulumaniso alulunganga;Okwesithathu, ukuthwala kuneziphene okanye ukulungiswa okungafanelekanga, ngokukodwa ukukhutshwa kukhulu kakhulu;Okwesine, kukho ukungqubana kunye nokungqubana phakathi kwamalungu ajikelezayo kunye namalungu amileyo
(2) Ukungcangcazela kwe-Hydraulic, ukungcangcazela kweyunithi okubangelwa ukungalingani kwamanzi ageleza kwimbaleki.
Izizathu: okokuqala, i-vane yesikhokelo yonakalisiwe kwaye ibholithi yaphukile, okukhokelela ekuvulekeni okwahlukileyo kwesikhokelo kunye nokuhamba kwamanzi okungalinganiyo malunga nomgijimi;Okwesibini, kukho i-sundries kwi-volute okanye umgijimi uvaliwe ngee-sundries, ukwenzela ukuba ukuhamba kwamanzi kujikeleze umgijimi kungalingani;Okwesithathu, ukuhamba kwamanzi kwi-tube eyidrafti ayizinzile, okubangelwa utshintsho lwexesha elithile kuxinzelelo lwamanzi lwetyhubhu eyidrafti, okanye umoya ungena kwimeko ye-spiral ye-hydraulic turbine, ebangela ukungcangcazela kweyunithi kunye nokugquma kwamanzi.
(3) Ukungcangcazela kombane kubhekiselele ekushukumeni kweyunithi okubangelwa kukulahleka kwebhalansi okanye utshintsho olukhawulezileyo lobungakanani bombane.
Izizathu: okokuqala, inqanaba lesithathu langoku lejeneretha alinakulinganiswa ngokunzulu.Ngenxa yokungalingani kwangoku, amandla e-electromagnetic ezigaba ezintathu azilingani;Okwesibini, utshintsho olukhawulezileyo lwangoku olubangelwa yingozi yombane lukhokelela ekungangqinelaniyo ngoko nangoko kwesantya sejenereyitha kunye neinjini yomoya;Okwesithathu, i-gap engalinganiyo phakathi kwe-stator kunye ne-rotor ibangela ukungazinzi kwentsimi yamagnetic ejikelezayo.
(4) I-vibration ye-Cavitation, i-unit vibration ebangelwa yi-cavitation.
Izizathu: okokuqala, i-amplitude ye-vibration ebangelwa ukungalingani kwe-hydraulic yanda ngokunyuka kokuhamba;Okwesibini, ukunyakaza okubangelwa ngumgijimi ongalinganiyo, uxhulumaniso olubi lweyunithi kunye ne-eccentricity, kwaye i-amplitude iyanda ngokunyuka kwesantya esijikelezayo;Okwesithathu kukungcangcazela okubangelwa ngujenereyitha wombane.I-amplitude iyanda ngokunyuka kwe-excitation current.Xa i-excitation isusiwe, i-vibration inokuphela;Okwesine kukungcangcazela okubangelwa yi-cavitation erosion.I-amplitude yayo inxulumene nommandla womthwalo, ngamanye amaxesha uphazamisekile kwaye ngamanye amaxesha unobundlobongela.Kwangaxeshanye, kukho ingxolo yokunkqonkqoza kwityhubhu eyidrafti, kwaye kukho ujingi kwi-vacuum meter.
I-4, iqondo lobushushu lephedi yeyunithi liyenyuka kwaye liphezulu kakhulu
(1) Unobangela
1. Izizathu zokugcinwa kunye nokufakwa: ukuvuza kwe-oyile ye-oyile, indawo yokufakela engafanelekanga ye-pitot tube, i-gap ye-tile engafanelekanga, i-unit vibration engaqhelekanga ebangelwa ngumgangatho wofakelo, njl.
2. Izizathu zokusebenza: ukusebenza kwindawo yokungcangcazela, ukusilela ekuqwalaseleni umgangatho ongaqhelekanga we-oyile kunye nenqanaba le-oyile, ukusilela ukongeza i-oyile ngexesha, ukusilela ekuqwalaseleni ukuphazamiseka kwamanzi okupholisa kunye nokungonelanga komthamo wamanzi, okukhokelela ekunciphiseni kwexesha elide. ukusebenza ngokukhawuleza komatshini, njl.
(2) Isibambo
1. Xa ukushisa okuthwala kuphakama, jonga kuqala ioli yokuthambisa, yongeza ioli eyongezelelweyo ngexesha okanye udibanise ukubuyisela ioli;Lungisa uxinzelelo lwamanzi okupholisa okanye utshintshe indlela yokubonelela ngamanzi;Vavanya ukuba ingaba ukushukuma kweyunithi kuyawugqitha umgangatho.Ukuba i-vibration ayikwazi ukupheliswa, iya kuvalwa;
2. Kwimeko yokukhusela ubushushu, jonga ukuba ukuvala kuqhelekile kwaye ukhangele ukuba i-bearing bush iyatshiswa.Emva kokuba isihlahla sitshisiwe, faka isihlahla esitsha endaweni yaso okanye usile kwakhona.
5,Ukusilela kulawulo lwesantya
Xa uvulo lwerhuluneli luvalwe ngokupheleleyo, imbaleki ayinakuyeka de kube indawo yokuvula isikhokelo ayinakulawulwa ngokufanelekileyo.Le meko ibizwa ngokuba kukusilela kulawulo lwesantya.Izizathu: okokuqala, uxhulumaniso lwe-vane yesikhokelo lugobile, olungenakukwazi ukulawula ngokufanelekileyo ukuvulwa kwe-vane yesikhokelo, ukwenzela ukuba i-vane yesikhokelo ingavalwa, kwaye iyunithi ayinakuyeka.Kufuneka kuqatshelwe ukuba ezinye iiyunithi ezincinci azinazo izixhobo zokuqhafaza, kwaye iyunithi ayinakumisa umzuzwana phantsi kwesenzo se-inertia.Ngeli xesha, musa ngempazamo ukucinga ukuba ayikavalwa.Ukuba uqhubeka nokuvala i-vane yesikhokelo, intonga yokudibanisa iya kugoba.Okwesibini, ukungaphumeleli kokulawulwa kwesantya kubangelwa ukungaphumeleli kwerhuluneli ezenzekelayo.Kwimeko yokusebenza ngokungaqhelekanga kweyunithi ye-injini ye-injini yamanzi, ngakumbi xa kukho ingxaki ekusebenzeni ngokukhuselekileyo kweyunithi, zama ukumisa umatshini ngokukhawuleza unyango.Ukubaleka kancinci kuya kwandisa kuphela isiphene.Ukuba irhuluneli ayiphumelelanga kwaye isixhobo sokuvula sesikhokelo asinakuyeka, ivalve engundoqo yeinjini yomoya iya kusetyenziswa ukunqumla ukuhamba kwamanzi kwiinjini yomoya.
Ezinye iindlela zonyango: 1. Ukucoca rhoqo i-sundries yendlela yesikhokelo samanzi, yigcine icocekile, kwaye rhoqo ugcwalise indawo eshukumayo;2. Indawo yokulahla inkunkuma kufuneka isetwe kwindawo yokungena kwaye icocwe rhoqo;3. Kwi-injini ye-hydraulic kunye nasiphi na isixhobo sesithuthi, nikela ingqalelo ekutshintsheni kwangethuba iiphedi zebrake kwaye wongeze i-oyile yebhuleki.
