Mu rwego rwo kwihuta mu iterambere ry’inganda zigezweho z’umuyaga, cyane cyane - ingufu ku nkombe z’umuyaga no ku nkombe z’umuyaga, kunyeganyega byabaye kimwe mu bintu by’ibanze bigira ingaruka ku mutekano w’umuyaga w’umuyaga, igihe cyo kubaho, kubyara amashanyarazi, hamwe n’ibikorwa byo kubungabunga no kubungabunga. Mugihe uburebure bwa turbine hub bukomeje kwiyongera, uburebure bwicyuma bukomeza kwiyongera, kandi ubushobozi bwa - bumwe bukomeza kwiyongera, ibibazo nko kunyeganyega umuyaga, umunara wa resonance, guhindagurika kwicyuma, guhindagurika kwihererekanyabubasha, hamwe no kunyeganyeza umusingi uhura na turbine yumuyaga mugihe cyo gukora bigenda bigaragara cyane.
None, ni ukubera iki ari ngombwa kunyeganyega bikenewe kugirango ingufu z'umuyaga zikorwe? Umuyaga uhindagurika, umuyaga, umuyaga wogosha, hamwe nigicucu cyigicucu cyumunara bitera ibyuma guhura nigihe gitandukanye, biganisha ku gukubita no guhinda umushyitsi, byanduzwa ihuriro, uruzitiro runini, garebox, n umunara, bikaviramo guhinda umushyitsi. Impinduka ya misa itabangikanye, guhuza imiyoboro nyamukuru, kwambara, hamwe na garebox ya gare ya meshing bigira ingaruka zose zitanga umuvuduko mwinshi -, ibyo bikaba aribyo bitera kunanirwa kwihererekanyabubasha. Umunara ni inyubako yoroheje, yoroheje ifite icyiciro cya mbere - itondekanya inshuro karemano, bigatuma ikunda kumvikana hamwe ninshuro zizunguruka hamwe ninshuro zanyuze. Iyo resonance imaze kubaho, amplitude yinyeganyeza yongerewe cyane, ibangamira umutekano wimiterere.
Ni izihe ngaruka kunyeganyega bitera turbine z'umuyaga? Mugihe gikomeza kunyeganyega, ubuzima bwumunaniro wa bokisi, ibyuma, shitingi nyamukuru, na sisitemu yaw bigabanuka cyane, kandi igipimo cyo gutsindwa cyiyongera cyane. Kunyeganyega birashobora gutuma umunara wa flange uhinduka hamwe nibice bikuru byingenzi bigabanuka, kandi mubihe bikomeye, umunaniro urashobora kugaragara muri weld. Kurenza urugero rwo kunyeganyega bizatera sisitemu nyamukuru yo kugenzura imitwaro, kugabanya umuvuduko, no kurinda umutekano, bigabanya mu buryo butaziguye igihe cyo kubyara amashanyarazi n’ibisohoka. Kunyeganyega - kunanirwa bifitanye isano birenga 50% byabananiye umuyaga mwinshi, kandi hejuru - kubungabunga ubutumburuke no gukora ku nyanja no kubungabunga amafaranga ni menshi cyane. Igihe kirekire - rezonanse cyangwa kunyeganyega gukabije birashobora gutuma habaho gucikamo ibyuma, guhindura umunara, kwangirika kwishingiro, ndetse nimpanuka zikomeye z'umutekano.
Iyi ngingo itangiza ishyirwa mu bikorwa rya vibration dampers kumashanyarazi yumuyaga. Icyuma nikintu kinyeganyega cyane, cyane cyane cyerekana gukubita, kunyeganyega, guhindagurika, no gushushanya - byatewe no kunyeganyega kutaringaniye. Imbere yatunganijwe neza, yashyizwe kuri 20% –40% yuburebure bwicyuma, koresha umurongo rusange, amasoko, hamwe nuburyo bwo kumanura kugirango uhuze ninshuro yinyeganyeza yicyuma, uhagarike neza - na kabiri - gutondekanya kunyeganyega no guhindagurika, kugabanya ubuzima bwumunaniro kumizi yicyuma, no kwagura ubuzima bwicyuma.
Gukoresha ibyuma byinyeganyeza bigabanya amplitude ya vibration vibration ku kigero cya 30% - 60%, bigabanya kwangirika kwumunaniro wibyuma hejuru ya 40%, bigabanya ibyago byo guturika no gutemba, kandi bikagabanya ingaruka zitaringanijwe ziterwa no kunyeganyega.
Inganda zikoresha ingufu z'umuyaga zikunze gukoresha vibrasiyo yubwoko butandukanye namahame yakazi. Ubwoko bukoreshwa cyane nubwoko bwahinduwe neza, bugizwe na misa, isoko, na damper. Umuyoboro uhujwe ninshuro nyamukuru yinyeganyeza ya turbine yumuyaga. Iyo kunyeganyega bibaye, guhagarika misa bigenda muburyo butandukanye kugirango ukoreshe ingufu. Ifite imiterere yizewe, ingaruka zihamye, hamwe nuburyo bugaragara.
Turbine yumuyaga wo hanze ikorera mubidukikije inshuro nyinshi zikaze kuruta turbine zo ku nkombe. Kubwibyo rero, kunyeganyega bigomba kuba byujuje ibyangombwa bisabwa byo kurwanya ruswa, harimo gushyushya - dip galvanizing, 316L ibyuma bitagira umwanda, icyuma cya Dacromet, gupima umunyu mu masaha arenga 1000, hamwe n’imikorere ihamye ku bushyuhe buri hagati ya dogere- 40 na dogere 80. Amafaranga yo gufata neza hanze ni menshi cyane, bisaba gushushanya igihe kirekire. Hydraulic damper igomba kandi kuba yarateguwe kugirango hirindwe amavuta ashobora kwanduza inyanja.
Ni izihe nyungu zifatika imirima yumuyaga ishobora kunguka mugukoresha Vibration Damper?
Kongera ingufu z'amashanyarazi, kugabanuka kunyeganyega - byatumye ingufu zigabanuka ndetse nigihe cyo gutaha, imikorere ihamye mu turere tw’umuyaga uhuha, hamwe n’amashanyarazi muri rusange yiyongereyeho 2% –8%; igihe kinini cyo kubaho cyibice byingenzi, hamwe nubuzima bwicyuma bwiyongereyeho 20% –40%, ubuzima bwa gearbox bwiyongereyeho 30% –50%, naho umunaniro wumunara wagabanutseho 30% –60%; yagabanije cyane ibikorwa byo kubungabunga no kubungabunga, bike - ibikorwa byo kubungabunga ubutumburuke, agasanduku gare gake hamwe nogusimbuza, kuzigama ibihumbi kugeza ku bihumbi icumi byamadorari y’Amerika kuri turbine y’umuyaga ku mwaka; guteza imbere umutekano muri rusange muri turbine, kwirinda resonance, kongera ubuzima mu gihe cya serwakira, umutingito, n’imivumba, no kugabanya ibyago byo kugabanuka kwa bolt no guturika; kugabanya urusaku, hamwe no kugabanuka kw urusaku rwindege nuburyo byubaka, byujuje ibisabwa byo kurengera ibidukikije no koroshya imishinga.
