Potengera kukula kwachangu kwamakampani amakono opanga magetsi opangira magetsi oyendera mphepo, makamaka -mphamvu zamphamvu zopangira magetsi akunyanja ndi m'mphepete mwa nyanja, kugwedezeka kwakhala chimodzi mwazinthu zazikulu zomwe zimakhudza chitetezo cha makina opangira mphepo, moyo wautali, kupanga magetsi, komanso ndalama zoyendetsera ndi kukonza. Pamene kutalika kwa malo opangira makina opangira mphepo kukukulirakulira, kutalika kwa tsamba kumachulukirachulukira, ndipo -kuchuluka kwa mayunitsi kumapitilira kukula, mavuto monga kugwedezeka kwa mphepo, kumveka kwa nsanja, kugwedezeka kwa mabala, kugwedezeka kwa tchani, ndi kugwedezeka kwa maziko koyang'anizana ndi ma turbine amphepo panthawi yogwira ntchito akuchulukirachulukira.
Chifukwa chake, chifukwa chiyani chotsitsa chotsitsa chamagetsi chili chofunikira pakugwiritsa ntchito mphamvu zamphepo? Mphepo yamkuntho, mphepo yamkuntho, mphepo yamkuntho, ndi mthunzi wa nsanja zimapangitsa kuti masambawo azigwedezeka nthawi ndi nthawi, zomwe zimapangitsa kuti mapiko agwedezeke ndi kugwedezeka, komwe kumatumizidwa ku hub, shaft yaikulu, gearbox, ndi nsanja, zomwe zimapangitsa kugwedezeka kosalekeza. Kusalinganika kwa ma impeller, kusalunjika bwino kwa shaft, kuvala, ndi ma gearbox meshing amakhudza zonse zimapanga -kugwedezeka kwakukulu, zomwe ndizomwe zimayambitsa kulephera kwa tcheni chotumizira mauthenga. Chinsanjachi ndi chowonda, chosinthika ndipo chimakhala chocheperako{{3}kutengera ma frequency achilengedwe, zomwe zimapangitsa kuti zikhala tcheru ndi ma frequency a chala komanso ma frequency a blade. Pamene resonance ichitika, kugwedezeka kwa matalikidwe kumakulitsidwa kwambiri, ndikuwopseza chitetezo chadongosolo.
Ndi zoopsa zotani zomwe kugwedezeka kumayambitsa ma turbines amphepo? Pansi pa kugwedezeka kosalekeza, moyo wotopa wa ma gearbox, mayendedwe, ma shafts akuluakulu, ndi machitidwe a yaw amafupikitsidwa kwambiri, ndipo kulephera kumakula kwambiri. Kugwedezeka kungayambitse mabawuti a nsanja ndi ma bawuti akuluakulu kuti asungunuke, ndipo zikavuta kwambiri, ming'alu ya kutopa imatha kuwoneka muzowotcherera. Kupyola malire a vibration kumayambitsa kuchepetsa katundu wa makina olamulira, kuchepetsa liwiro, ndi chitetezo chotseka, kuchepetsa mwachindunji nthawi yopangira mphamvu ndi kutulutsa. Kugwedera-zolephereka zokhudzana ndi kugwedezeka kumapangitsa kupitilira 50% ya kulephera kwa makina onse amphepo, ndipo kukwera-kukonza mtunda ndi kugwirira ntchito panyanja ndi kukonza ndikukwera kwambiri. -kumveka kwanthawi yayitali kapena kugwedezeka kwambiri kungayambitse kung'ambika kwa mabala, kupotokola kwansanja, kuwonongeka kwa maziko, ngakhalenso ngozi zoopsa zachitetezo.
Nkhaniyi ikufotokoza za kagwiritsidwe ntchito ka ma vibration dampers pamasamba a turbine. Ma blades ndi zinthu zomwe zimanjenjemera kwambiri, zomwe zimawonetsa kuthwanima, kugwedezeka, kuwuluka, ndi icing-kuchititsa kugwedezeka kosakwanira. Zonyezimira zamkati, zoyikidwa pa 20% -40% ya utali wa tsamba, zimagwiritsa ntchito chipika, akasupe, ndi zonyowa kuti zigwirizane ndi kugwedezeka kwa tsamba, kupondereza choyamba- ndi chachiwiri{6}kukonza kugwedezeka ndi kugwedezeka kwamphamvu, kuchepetsa mizu yopindika ndi kutopa kwa moyo.
Kugwiritsiridwa ntchito kwa ma vibration dampers kumachepetsa kugwedezeka kwa tsamba ndi 30% -60%, kumachepetsa kutopa kwa tsamba ndi 40%, kumachepetsa chiwopsezo cha kung'ambika kwa tsamba ndikumangirira, ndikuchepetsa kukhudzidwa kosagwirizana ndi kugwedezeka kwa icing.
Makampani opanga mphamvu zamphepo nthawi zambiri amagwiritsa ntchito zida zoziziritsa kukhosi zamitundu yosiyanasiyana komanso mfundo zogwirira ntchito. Mtundu womwe umagwiritsidwa ntchito kwambiri ndi damper ya tuned mass block, yomwe imakhala ndi block block, kasupe, ndi damper. Mafupipafupi amasinthidwa ku kugwedezeka kwakukulu kwa turbine yamphepo. Kugwedezeka kukachitika, chipika chachikulu chimasunthira mbali ina kuti idye mphamvu. Ili ndi dongosolo lodalirika, zotsatira zokhazikika, komanso kugwiritsidwa ntchito kwakukulu.
Ma turbine amphepo akunyanja amagwira ntchito movutirapo kangapo kuposa ma turbine akumtunda. Chifukwa chake, chotenthetsera chotenthetseracho chiyenera kukwaniritsa zofunika kwambiri kuti zisachite dzimbiri, kuphatikizapo kutentha-dip galvanizing, 316L stainless steel, Dacromet coating, kuyesa kupopera mchere kwa maola oposa 1000, ndi kugwira ntchito mokhazikika pa kutentha koyambira -40 digiri mpaka 80 digiri . Mitengo yokonza kunyanja ndi yokwera kwambiri, zomwe zimafunikira kuti pakhale moyo wautali. Chowotcha cha hydraulic chiyeneranso kupangidwa kuti chiteteze kuchucha kwa mafuta komwe kungawononge nyanja.
Ndi maubwino otani omwe mafamu amphepo angapindule pogwiritsa ntchito Vibration Damper?
Kuchulukitsidwa kwa magetsi, kugwedera kwamphamvu-kunachititsa kuti magetsi azichepa ndi nthawi yocheperako, kugwira ntchito mokhazikika m'madera a mphepo yamkuntho, komanso kuwonjezeka kwa mphamvu zonse za 2% -8%; Kutalikitsa moyo wa zida zapakati, ndi moyo wamasamba ukuwonjezeka ndi 20% -40%, moyo wamagiya wakwera ndi 30% -50%, ndi kuwonongeka kwa kutopa kwa nsanja kumachepetsedwa ndi 30% -60%; zachepetsa kwambiri ndalama zoyendetsera ntchito ndi kukonza, zochepera-zokonza malo okwera kwambiri, ma gearbox ocheperako ndi zotengera zina, kupulumutsa masauzande mpaka masauzande a madola aku US pa turbine yamphepo yakunyanja pachaka; kupititsa patsogolo chitetezo cha turbine, kupeŵa kumveka, kupititsa patsogolo kupulumuka pansi pa mvula yamkuntho, zivomezi, ndi mafunde, komanso kuchepetsa chiopsezo cha kumasulidwa kwa bolt ndi kusweka kwapangidwe; Phokoso locheperako, locheperako komanso phokoso lachimake, kukwaniritsa zofunikira zachitetezo cha chilengedwe ndikuthandizira kuvomerezedwa kwa polojekiti.
