Iindidi zokuVelisa ubungozi beSeti

Ukungcangcazela kweseti ye-hydro-generator yahlukile kuleyo yomatshini wamandla ngokubanzi ukuya kumlinganiselo othile.Intshukumo yeyunithi yokungcangcazela iyabonakala, kodwa umthombo wokungcangcazela uhlala ufihliwe.Ukongeza kwi-vibration ebangelwa yinxalenye ejikelezayo okanye esisigxina yomatshini ngokwawo, impembelelo yamandla ombane kunye nomatshini wombane kunye noxinzelelo lokuhamba olusebenza kwindawo ephuphumayo ye-injini yomoya kwi-vibration yenkqubo kunye namalungu ayo kufuneka athathelwe ingqalelo. .Kukho izizathu ezininzi zokungcangcazela kweseti ye-hydro-generator, kwaye imithombo emininzi yokungcangcazela ihlala ikhona ngaxeshanye.Kukholelwa ngokubanzi ukuba imithombo yamandla ophazamiseko ebangela ukungcangcazela kweyunithi ubukhulu becala ivela kwi-hydraulic, umatshini kunye nemiba yombane, ezinxibelelana enye kwenye kwaye zihlala zithungelana kunye ukwenza ukungcangcazela okudityanisiweyo.

Ukungcangcazela ngokubanzi kweyunithi yokuvelisa amandla ombane akusayi kubangela ingozi kubasebenzi, kodwa xa ukungcangcazela kugqithise kumaxabiso avumelekileyo, ngakumbi ukungcangcazela kwexesha elide kunye nokuvakala, umgangatho wobonelelo lwamandla, ubomi benkonzo yeyunithi, ukusebenza kwezixhobo ezincedisayo kunye izixhobo, isiseko seyunithi kunye nezakhiwo ezijikelezileyo, kwaye zonke zizisa umonakalo omkhulu ekusebenzeni okukhuselekileyo noqoqosho kwesikhululo sombane wamanzi.

Ukwenza iseti yobungozi kunokwahlulwa ngokwezi ndidi zilandelayo:

Ikhokelela ekwakhiweni kunye nokwandiswa kwendawo yomonakalo wokudinwa phakathi kwentsimbi kunye ne-weld, ekhokelela kwiintanda, kunye nomonakalo wokuqhekeka kunye ne-scrap.

Ukukhulula ezinye i-fasteners zeyunithi aziyi kukhokelela kuphela ekuqhekekeni kwe-fasteners ngokwazo, kodwa kwandise ukungcangcazela kwamacandelo okudibanisa kunye nokukhawulezisa umonakalo wabo.

Iqondo lokunxiba ngokulinganayo kwamacandelo ajikelezayo eyunithi yokukhawuleza.I-shaft enkulu ijiwulwa ngamandla, i-shaft kunye nokunyuka kwamaqondo obushushu, ithwala ilahleko evuthayo;Ijenereyitha ye-rotor vibration inkulu kakhulu, yongeza iqondo lokunxiba leringi yokutyibilika kunye nebrashi, yandisa iqondo lobushushu, itshise isihlahla esithwalayo, yandisa intlantsi yebrashi.

Uxinzelelo lwe-vortex pulsating olwenziwe kumbhobho womsila luya kwenza inkqubo yokuphuphuma kwe-oscillate, imveliso yeyunithi ujingi, kunye nodonga lwe-tailpipe crack.Kwiimeko ezinzima, yonke inkonzo ye-tailpipe inokonakala.

Iziphumo ze-resonance ye-iturbine yamanzi zibi kakhulu.Umzekelo, i-resonance phakathi kwesixhobo seyunithi kunye nesityalo singonakalisa isityalo sonke kunye nesityalo ukuya kumazinga ahlukeneyo.

Ukungcangcazela kweHydraulic kukungcangcazela okubangelwa kukuphazamiseka koxinzelelo lwe-hydrodynamic yenxalenye yehydraulic ye-iturbine, ebizwa ngokuba yi-hydraulic vibration.Izinto ze-hydraulic ezibangela ukunyakaza ngokukodwa zibandakanya: ukungazinzi kwe-hydraulic okubangelwa yi-low-frequency vortex band ye-tailpipe, inkqubo ye-karman vortex, i-blade vortex, ukungazinzi kwinkqubo yokuguquka, ukungalingani kwe-hydraulic, i-cavitation ye-cavitation, i-jet clearance (i-axial flow turbine) kwaye nangokunjalo.

Ummandla we-vortex ojikelezayo ophantsi kumbhobho womsila luhlobo oluthile lokuqukuqela okungazinzanga kumbhobho womsila weinjini yomoya ye-Francis kunye ne-axial distance turbine phantsi komthwalo ongaphelelanga.Xa i-turbine isebenza phantsi kwemeko ye-off-design, i-pressure pulsation ivame ukuvela kwi-tailpipe ngenxa yempembelelo yokujikeleza kwamanzi, ukuchithwa kwe-vortex kunye ne-cavitation kwi-runner outlet.Ngokukodwa emva kokuvela kwebhendi enkulu ye-vortex kwi-tailpipe, i-vortex band ijikeleza kumbhobho kwi-frequency ephantse imisiwe, ebangela ukunyanzeliswa kwe-low-frequency pulsation yokuhamba kwamanzi.Xa ukuhamba kwamanzi kwenzeka kwi-tube, i-pulsation yoxinzelelo iya kubangela ukungcangcazela kodonga lombhobho womsila, umgijimi, indlela yesikhokelo samanzi, i-volute kunye nombhobho woxinzelelo.

Amanyathelo othintelo kunye nonyango:

Lungiselela uyilo lwe-hydraulic.I-Angle engalunganga ye-Angle ye-airfoil, uyilo olufanelekileyo lomthetho wokusasazwa kwe-outlet ye-blade, isithsaba esifanelekileyo kunye ne-cone yokukhupha, kunye nembaleki enamacangca ancedisayo inokuqwalaselwa kwimbaleki ephezulu exutywe ngentloko.

Hlala kude nommandla womsebenzi wokungcangcazela.Shintsha isantya sokuhamba kunye nokujikeleza kwamanzi, njengokwandisa i-cone yokukhupha, ukwandisa icandelo elide le-cone, ukwandisa i-Angle yombhobho we-tail, ukwandisa i-baffle plate kunye ne-baffle plate, ukulawula i-vortex belt eccentricity. , njl.

Ngethuba lokusebenza kweyunithi, ukunikezelwa komoya okufanelekileyo kuqhutyelwa kwindawo yangoku ye-eddy, ngokuqhelekileyo ukunikezelwa komoya wendalo, okanye ukunyanzeliswa komoya xa kuyimfuneko.

Ezi ndidi zingentla zahlulwe yi-Dingbo Power, ukuba unombuzo malunga ne iijenereyitha zedizili ,pls qhagamshelana ne-Dingbo Power ezinemveliso ezigubungela iCummins, iPerkins, iVolvo, iYuchai, iShangchai, iDeutz, Ricardo , MTU, Weichai njl.
