Ngethuba lenkqubo yophuhliso lwemveliso, isebe lophando lobugcisa kunye nesebe lophuhliso lifumene ukuba i-rotor yayinomsebenzi ocacileyo wokungcangcazela xa ifikelele kwi-100,000 revolutions. Le ngxaki ayichaphazeli kuphela ukuzinza kokusebenza kwemveliso, kodwa inokubangela ingozi kubomi benkonzo kunye nokhuseleko lwezixhobo. Ukuze sihlalutye nzulu unobangela wengxaki kwaye sifune izisombululo ezisebenzayo, siye saququzelela ngenkuthalo le ntlanganiso yengxoxo yobugcisa ukuze sifunde kwaye sihlalutye izizathu.
1. Uhlalutyo lwemiba ye-rotor vibration
1.1 Ukungalungelelani kwe-rotor ngokwayo
Ngethuba lenkqubo yokuvelisa i-rotor, ngenxa yokusabalalisa izinto ezingalinganiyo, iimpazamo zokuchaneka kwe-machining kunye nezinye izizathu, isikhungo sayo sobunzima asikwazi ukuhambelana neziko lokujikeleza. Xa ujikeleza ngesantya esiphezulu, oku kungalingani kuya kuvelisa amandla e-centrifugal, okuya kubangela ukungcangcazela. Nokuba ukungcangcazela akubonakali ngesantya esiphantsi, njengoko isantya sinyuka siye kuthi ga kwi-100,000 revolutions, ukungalingani okuncinci kuya kwandiswa, kubangele ukungcangcazela kuqine.
1.2 Ukuthwala ukusebenza kunye nofakelo
Ukukhetha okungafanelekanga kohlobo lokuthwala: Iindidi ezahlukeneyo zeebheringi zinamandla ahlukeneyo okuthwala, isantya sesantya kunye neempawu zokudambisa. Ukuba i-bearing ekhethiweyo ayikwazi ukuhlangabezana nesantya esiphezulu kunye neemfuneko zokusebenza ezichanekileyo ze-rotor kwii-revolutions ze-100,000, ezifana neebhola zebhola, i-vibration ingenzeka ngesantya esiphezulu ngenxa yokubambisana, ukufudumeza kunye nokugqoka phakathi kwebhola kunye nomzila wokugijima.
Ukuchaneka kofakelo lwe-bearing angonelanga: Ukuba i-coaxiality kunye nokuphambuka kwe-verticality ye-bearing kukhulu ngexesha lofakelo, i-rotor iya kufakwa kwi-radial kunye ne-axial force eyongezelelweyo ngexesha lokujikeleza, ngaloo ndlela ibangela ukungcangcazela. Ukongeza, ukulayisha kwangaphambili okungafanelekanga kuya kuchaphazela ukuzinza kwayo kokusebenza. Ukulayisha kwangaphambili okugqithisileyo okanye okunganelanga kunokubangela iingxaki zokungcangcazela.
1.3 Ukuqina kunye nokuvakala kwenkqubo ye-shaft
Ukungonelanga kwe-rigidity ye-shaft system: Izinto ezinjengezinto eziphathekayo, ububanzi, ubude be-shaft, kunye nokwakheka kwamacandelo adityaniswe kwi-shaft kuya kuchaphazela ukuqina kwenkqubo ye-shaft. Xa ukuqina kwenkqubo ye-shaft ihlwempuzekile, i-shaft iyancipha ukugoba kunye nokuguqulwa phantsi kwe-centrifugal force eyenziwa yi-high-speed rotation ye-rotor, ebangela ukuba i-vibration. Ngokukodwa xa usondela kwi-frequency yendalo ye-shaft system, i-resonance iyakwazi ukwenzeka, ibangela ukuba ukunyakaza kunyuke ngokukhawuleza.
Ingxaki ye-resonance: Inkqubo ye-rotor ine-frequency yayo yendalo. Xa isantya se-rotor sisondele okanye silingana ne-frequency yayo yendalo, i-resonance iya kwenzeka. Ngaphantsi kwesantya esiphezulu sokusebenza kwe-100,000 rpm, nokuba yizinto ezincinci zangaphandle, ezifana nemikhosi engalinganiyo, ukuphazamiseka kwe-airflow, njl., xa ihambelana nokujikeleza kwendalo kwenkqubo ye-shaft, inokubangela ukungcangcazela okunamandla.
1.4 Imiba yokusingqongileyo
Utshintsho lobushushu: Ngexesha lokusebenza ngesantya esiphezulu se-rotor, ubushushu benkqubo buya kunyuka ngenxa yokuveliswa kobushushu obukhukhulayo kunye nezinye izizathu. Ukuba i-coefficients yokwandiswa kwe-thermal yamacandelo afana ne-shaft kunye ne-bearing iyahluka, okanye iimeko zokutshatyalaliswa kobushushu zihlwempuzekileyo, ukukhutshwa okufanelekileyo phakathi kwamacandelo kuya kutshintsha, kubangele ukungcangcazela. Ukongeza, ukuguquguquka kobushushu be-ambient kunokuchaphazela inkqubo ye-rotor. Ngokomzekelo, kwindawo ephantsi kweqondo lokushisa, i-viscosity ye-oyile yokuthambisa yanda, enokuthi ichaphazele umphumo we-lubrication we-bearing kwaye ibangele ukungcangcazela.

Emva kokugqiba ukulungiswa kwangaphambili, i-rotor iphakanyiselwa kwisantya esiphezulu se-100,000 revolutions for fine dynamic balancing adjustment ukuze kuqinisekiswe ukuba ukungalingani kwe-rotor kulawulwa ngaphakathi kwinqanaba elincinci kakhulu ngexesha lokusebenza kwesantya esiphezulu, ngaloo ndlela kuncitshiswe ngokufanelekileyo ukunyakaza okubangelwa ukungalingani.
2.2 Ukuthwala uKhetho lokuSebenza kunye noFakelo oluchanekileyo
Ukuphonononga kwakhona ukhetho lokuthwala: Ukudibanisa nesantya se-rotor, umthwalo, ubushushu bokusebenza kunye nezinye iimeko zokusebenza, khetha iintlobo zokuthwala ezilungele ngakumbi ukusebenza ngesantya esiphezulu, njengeebhodi zebhola ze-ceramic, ezineenzuzo zobunzima bokukhanya, ubunzima obuphezulu. , i-coefficient ephantsi ye-friction, kunye nokumelana nokushisa okuphezulu. Banokubonelela ngokuzinza okungcono kunye namanqanaba aphantsi okungcangcazela kwisantya esiphezulu se-100,000 revolutions. Kwangaxeshanye, cinga ukusebenzisa iibheringi ezineempawu ezintle zokudambisa ukufunxa ngokufanelekileyo kwaye ucinezele ukungcangcazela.
Ukuphucula ukuchaneka kofakelo lokuthwala: Sebenzisa iteknoloji yofakelo oluphezulu kunye nezixhobo zokufakela ezichanekileyo ukuze ulawule ngokungqongqo iimpazamo ze-coaxiality kunye ne-verticality ngexesha lofakelo lokuthwala ngaphakathi kwinqanaba elincinci kakhulu. Ngokomzekelo, sebenzisa isixhobo sokulinganisa i-laser coaxiality ukubeka iliso kunye nokulungelelanisa inkqubo yokufakela ukuthwala ngexesha langempela ukuqinisekisa ukuchaneka okuhambelanayo phakathi kwe-shaft kunye nokuthwala. Ngokuphathelele ukuthwala kwangaphambili, ngokohlobo kunye neemeko ezithile zokusebenza zokuthwala, misela ixabiso elifanelekileyo lokulayisha kwangaphambili ngokubala okuchanekileyo kunye novavanyo, kwaye usebenzise isixhobo esikhethekileyo sokulayisha kwangaphambili ukuze usebenzise kwaye ulungelelanise ukulayishwa kwangaphambili ukuqinisekisa ukuzinza kokuthwala ngexesha eliphezulu. -ukusebenza ngesantya.
2.3 Ukomeleza ukuqina kwe-shaft system kunye nokuphepha ukuvakala kwesandi
Ukuphucula uyilo lwenkqubo ye-shaft: Ngokuhlalutya izinto ezinqamlekileyo kunye nezinye iindlela, ulwakhiwo lwe-shaft luphuculwe kwaye luyilwe, kwaye ukuqina kwenkqubo ye-shaft kuphuculwe ngokunyusa i-diameter ye-shaft, usebenzisa izixhobo eziphezulu okanye ukuguqula i-cross-sectional. ubume be-shaft, ukuze kuncitshiswe i-deformation yokugoba ye-shaft ngexesha lokujikeleza kwesantya esiphezulu. Ngelo xesha, ukulungiswa kwamacandelo kwi-shaft kulungelelaniswa ngokufanelekileyo ukunciphisa isakhiwo se-cantilever ukwenzela ukuba amandla e-shaft system afane.
Ukulungelelanisa kunye nokuphepha i-resonance frequency: Bala ngokuchanekileyo i-frequency yendalo ye-shaft system, kwaye ulungelelanise ukujikeleza kwendalo kwenkqubo ye-shaft ngokuguqula iiparitha zesakhiwo se-shaft system, njengobude, ububanzi, i-elastic modulus yezinto eziphathekayo, njl. , okanye ukongeza i-dampers, i-absorbers kunye nezinye izixhobo kwi-shaft system ukuyigcina kude nesantya sokusebenza se-rotor (100,000 rpm) ukuphepha ukwenzeka. yeresonance. Kwinqanaba loyilo lwemveliso, itekhnoloji yokuhlalutya i-modal ingasetyenziselwa ukuqikelela iingxaki ezinokwenzeka ze-resonance kunye nokwandisa uyilo kwangaphambili.
2.4 Ulawulo lokusingqongileyo
Ukulawula ubushushu kunye nokulawulwa kwe-thermal: Yila inkqubo efanelekileyo yokutshatyalaliswa kobushushu, njengokongeza i-heat sinks, usebenzisa ukupholisa umoya ngokunyanzeliswa okanye ukupholisa ulwelo, ukuqinisekisa ukuzinza kweqondo lokushisa kwenkqubo ye-rotor ngexesha lokusebenza ngesantya esiphezulu. Ukubala ngokuchanekileyo kunye nokuhlawulela ukwandiswa kwe-thermal yamacandelo abalulekileyo anjengama-shafts kunye neebheringi, njengokusebenzisa izithuba ezigciniweyo zokwandisa i-thermal okanye ukusebenzisa izinto ezinokuhambelana nokwandiswa kwe-thermal coefficients, ukuqinisekisa ukuba ukuchaneka kokuchaneka phakathi kwamacandelo akuchaphazeli xa ubushushu buguquka. Ngexesha elifanayo, ngexesha lokusebenza kwezixhobo, jonga utshintsho kwiqondo lokushisa ngexesha langempela, kwaye ulungelelanise ubushushu bokutshatyalaliswa kobushushu ngexesha ngenkqubo yokulawula ubushushu ukugcina ukuzinza kweqondo lokushisa kwenkqubo.
