Munguva yekugadzirwa kwechigadzirwa, dhipatimendi rekutsvagisa nekusimudzira rehunyanzvi rakaona kuti rota yaive nechiitiko chekuzunguzika chiri pachena payakasvika 100,000 revolutions. Dambudziko iri haringokanganisa kugadzikana kwekuita kwechigadzirwa, asi rinogonawo kutyisidzira hupenyu hwebasa uye kuchengetedzwa kwemidziyo. Kuti tiongorore zvakadzama chikonzero chedambudziko uye kutsvaga mhinduro dzinoshanda, takaronga musangano uyu wehunyanzvi hwekukurukurirana kuti tidzidze nekuongorora zvikonzero.
1. Kuongororwa kwezvinhu zve rotor vibration
1.1 Kusagadzikana kwe rotor pachayo
Munguva yekugadzira rotor, nekuda kwekusaenzana kwekugovera zvinhu, machining accracy zvikanganiso uye zvimwe zvikonzero, nzvimbo yayo yehukuru inogona kusapindirana nepakati pekutenderera. Kana ichitenderera ichimhanya zvakanyanya, kusaenzana uku kunoburitsa simba recentrifugal, rinokonzeresa kudedera. Kunyange kana kudengenyeka kusingaonekwe nekumhanya kwakaderera, sezvo kumhanya kunowedzera kusvika ku100,000 revolutions, kusaenzana kuduku kunowedzerwa, zvichiita kuti kudengenyeka kuwedzere.
1.2 Kutakura kuita uye kuiswa
Kusarudzika kwemhando yemhando yekusarudzika: Mhando dzakasiyana dzemabheya ane akasiyana kutakura mitoro, nhanho dzekumhanya uye dhizaini maitiro. Kana iyo yakasarudzwa inotakura isingakwanisi kusangana ne-high-speed uye yakakwirira-chaiyo yekushanda zvinodiwa zve rotor pa 100,000 revolutions, yakadai semabheji ebhora, kudengenyeka kunogona kuitika nekumhanya kukuru nekuda kwekukakavadzana, kupisa uye kupfeka pakati pebhora uye mujaho.
Kusakwana kutakura kugadzika kurongeka: Kana iyo coaxiality uye verticality kutsauka kweiyo kutakura kwakakura panguva yekuiswa, rotor ichaiswa pasi pekuwedzera radial uye axial masimba panguva yekutenderera, nekudaro zvichikonzera vibration. Pamusoro pezvo, zvisina kufanira kutakura preload zvinokanganisawo kugadzikana kwayo kwekushanda. Yakawandisa kana kusakwana preload inogona kukonzera matambudziko ekudedera.
1.3 Kuomarara uye resonance yeiyo shaft system
Kusakwana kuomarara kweiyo shaft system: Zvinhu zvakaita sechinhu, dhayamita, kureba kweshaft, uye marongerwo ezvikamu zvakabatana kune shaft zvinokanganisa kusimba kweiyo shaft system. Kana kuomarara kweiyo shaft system kwakashata, iyo shaft inowanzokotama uye deformation pasi pesimba recentrifugal rinogadzirwa nekumhanya-mhanya kutenderera kwe rotor, izvo zvinozoita kuti kudedera. Kunyanya kana ichisvika kune yakasikwa frequency ye shaft system, resonance inowanzoitika, zvichiita kuti vibration iwedzere zvakanyanya.
Resonance dambudziko: Iyo rotor system ine yayo yakasarudzika frequency. Kana iyo rotor kumhanya iri pedyo kana kuenzana neayo frequency frequency, resonance ichaitika. Pasi pekushanda kwepamusoro-kumhanya kwe100,000 rpm, kunyange zviduku zvekunze zvekunze, zvakadai semasimba asina kuenzana, kukanganiswa kwemhepo, nezvimwewo, kana zvichingofananidzwa nemasikirwo echisikigo che shaft system, zvinogona kukonzera kudengenyeka kwakasimba.
1.4 Zvinhu zvakatipoteredza
Kuchinja kwematembiricha: Munguva yekumhanya-mhanya kwe rotor, tembiricha yehurongwa inokwira nekuda kweiyo frictional heat generation uye zvimwe zvikonzero. Kana iyo yekupisa yekuwedzera coefficients yezvikamu zvakadai se shaft uye kutakura zvakasiyana, kana mamiriro ekupisa anopisa asina kunaka, chibvumirano chakakodzera pakati pezvikamu chichashanduka, zvichikonzera kudengenyeka. Mukuwedzera, kuchinja kwekushisa kwemukati kunogona kukanganisawo rotor system. Semuenzaniso, munzvimbo yakadzika-yekupisa, viscosity yemafuta ekuzora inowedzera, izvo zvinogona kukanganisa lubrication maitiro ekutakura uye kukonzera vibration.
2. Zvirongwa zvekuvandudza uye nzira dzehunyanzvi
2.1 Rotor dynamic balance optimization
Shandisa yakakwirira-chaiyo dynamic balancing midziyo kuti uite dynamic balance kugadzirisa pane rotor. Kutanga, ita preliminary dynamic balancing test at low speed kuyera kusaenzana kwe rotor uye chikamu chayo, uye zvishoma nezvishoma kuderedza kusaenzana nekuwedzera kana kubvisa zvipingamupinyi pane dzimwe nzvimbo pane rotor. Mushure mokupedza kururamisa kwekutanga, rotor inosimudzirwa kusvika kune yakakwirira ye 100,000 revolutions yezvakanaka dynamic balancing kugadzirisa kuti ive nechokwadi chokuti kusaenzana kwerotor kunodzorwa mukati mechikamu chiduku zvikuru panguva yekushanda kwepamusoro-soro, nokudaro zvinobudirira kuderedza kudengenyeka kunokonzerwa nekusaenzana.
2.2 Kutakura Optimization Sarudzo uye Precision Kuiswa
Ongororazve kutakura kusarudzwa: Yakasanganiswa neiyo rotor kumhanya, mutoro, tembiricha yekushanda uye mamwe mamiriro ekushanda, sarudza mhando dzekutakura dzinonyanya kukodzera kumhanyisa kumhanya, senge ceramic ball bearings, ine zvakanakira uremu huremu, kuomarara kwakanyanya. , yakaderera friction coefficient, uye yakakwirira tembiricha kuramba. Ivo vanogona kupa kugadzikana kuri nani uye kudzikisa kudengenyeka kwemazinga pakumhanya kukuru kwe100,000 revolutions. Panguva imwecheteyo, funga kushandisa mabearings ane hunhu hwakanaka hwekunyorovesa kuti unyatso kunwisa uye kudzvanya vibration.
Kuvandudza kubereka kuisirwa kwechokwadi: Shandisa yepamusoro yekuisa tekinoroji uye yakakwirira-chaiyo yekuisa maturusi kunyatso kudzora coaxiality uye verticality zvikanganiso panguva yekutakura kuisirwa mukati mediki diki renji. Semuenzaniso, shandisa laser coaxiality yekuyeresa chiridzwa chekutarisa uye kugadzirisa iyo yekuisa yekuisa maitiro munguva chaiyo kuti ive nechokwadi chekuenderana pakati pe shaft uye kubereka. Panyaya yekutakura preload, zvinoenderana nerudzi uye nemamiriro ekushanda echibereko, sarudza iyo yakakodzera preload kukosha kuburikidza nekuverenga chaiko uye kuyedza, uye shandisa yakakosha preload mudziyo kuisa uye kugadzirisa preload kuti ive nechokwadi chekugadzikana kweiyo kutakura panguva yakakwirira. -speed operation.
2.3 Kusimbisa kuomarara kweiyo shaft system uye kudzivirira resonance
Kugonesa shaft system dhizaini: Kuburikidza neinogumira chinhu chekuongorora uye dzimwe nzira, iyo shaft dhizaini inogadziridzwa uye yakagadzirwa, uye kuomarara kweiyo shaft sisitimu inovandudzwa nekuwedzera dhayamita yeshaft, uchishandisa yakakwirira-simba zvinhu kana kushandura muchinjiko-chikamu. chimiro che shaft, kuitira kuti uderedze kukotama deformation ye shaft panguva yekumhanya-mhanya kutenderera. Panguva imwecheteyo, kurongeka kwezvikamu pa shaft kunogadziriswa zvinonzwisisika kuderedza chimiro che cantilever kuitira kuti simba re shaft system riwedzere kufanana.
Kugadzirisa uye kudzivirira resonance frequency: Nyatsoverengera yakasikwa frequency ye shaft system, uye gadzirisa yakasarudzika frequency ye shaft system nekushandura magadzirirwo eiyo shaft system, senge kureba, dhayamita, elastic modulus yezvinhu, nezvimwe. , kana kuwedzera madhamu, mashock absorbers uye mamwe maturusi kune shaft system kuti ichengetedze kure nekumhanya kwekushanda kwe rotor (100,000 rpm) kudzivirira kuitika. resonance. Muchikamu chekugadzira chigadzirwa, modal yekuongorora tekinoroji inogona zvakare kushandiswa kufanotaura zvinogona kuitika resonance matambudziko uye kugadzirisa dhizaini kumberi.
2.4 Kudzora nharaunda
Kudzora tembiricha uye manejimendi ekupisa: Dhizaina inonzwisisika yekubvisa kupisa sisitimu, sekuwedzera madhishi ekupisa, uchishandisa kumanikidza kutonhora kwemhepo kana kutonhora kwemvura, kuve nechokwadi chekugadzikana kwekushisa kweiyo rotor system panguva yekumhanya-mhanya. Kunyatso kuverenga uye kubhadhara kuwedzera kwekushisa kwezvikamu zvakakosha zvakadai semashafts uye mabhengi, zvakadai sekushandisa zvakachengetwa zvivharo zvekuwedzera kwekushisa kana kushandisa zvinhu zvine machisi ekuwedzera kwemafuta ekuwedzera, kuve nechokwadi kuti kuenzanirana pakati pezvikamu hakukanganisi kana kutonhora kuchichinja. Panguva imwecheteyo, panguva yekushanda kwemidziyo, tarisa kushanduka kwekushisa munguva chaiyo, uye gadzirisa kupisa kwekupisa kupisa munguva kuburikidza nehurongwa hwekutonga kwekushisa kuchengetedza kugadzikana kwekushisa kwehurongwa.
3. Pfupiso
Vatsvagiri veHangzhou Magnet Power Technology Co., Ltd. vakaita ongororo yakazara uye yakadzama yezvinhu zvinobata rotor vibration uye vakaona zvinhu zvakakosha zvekusaenzana kwerotor pachayo, kutakura kuita uye kuisirwa, kusimba kweshaft uye resonance, mamiriro ekunze uye. kushanda medium. Mukupindura kune izvi zvinhu, nhevedzano yezvirongwa zvekuvandudza yakatsanangurwa uye inowirirana tekinoroji nzira dzakatsanangurwa.
