Dynamic Balancing Machines, Soft-Bearing vs. Hard-Bearing
Michina yekuenzanisa-ndege mbiri, kana michina yekuenzanisa, inoshandiswa kugadzirisa static uye ine simba kusaenzana.Iwo maviri marudzi akajairwa emagetsi ekuyeresa emuchina akagamuchira kugamuchirwa zvakanyanya ndiwo "wakapfava" kana unochinjika wekutakura muchina uye "wakaoma" kana wakaomarara wekubereka muchina.Kunyange hazvo pasina mutsauko pakati pemabhengi anoshandiswa, michina ine marudzi akasiyana ekumiswa.
Yakapfava Bearing Bancing Machines
Iyo yakapfava-inotakura muchina inowana zita rayo kubva pakuti inotsigira rotor kuti ive yakaenzana pamabheya akasununguka kufamba mune imwe nzira, kazhinji yakatwasuka kana perpendicularly kune rotor axis.Dzidziso iri shure kwemaitiro aya ekuenzanisa ndeyokuti rotor inoita seyakaturikwa pakati pemhepo apo kufamba kwe rotor kunopimwa.Iyo mechanical dhizaini yemuchina wakapfava wakaoma zvishoma, asi zvemagetsi zvinosanganisirwa zviri nyore kana zvichienzaniswa nemichina yakaoma.Dhizaini yemuchina wakapfava wekuenzanisa unobvumira kuti uiswe chero kupi, sezvo basa rinochinjika rinotsigira rinopa kuparadzaniswa kwechisikigo kubva kune chiitiko chiri pedyo.Izvi zvinobvumirawo kuti muchina ufambiswe usingakanganise kurongeka kwechishandiso, kusiyana nemichina yakaoma-kutakura.
Iyo resonance ye rotor uye bearing system inoitika pane imwe hafu kana pasi peiyo yakaderera kuenzanisa kumhanya.Kuenzanisa kunoitwa pane frequency yakakwirira kupfuura resonance frequency yekumisa.
Kunze kweiyi yekuti muchina wakapfava unotakurika unotakurika, unopa zvakawedzerwa zvakanakira kuve nekunzwa kwepamusoro pane michina yakaoma-inotakura inomhanya yakaderera;michina yakaoma inoyera simba iro rinowanzoda kukurumidza kuenzanisa.Chimwe chikomborero ndechokuti michina yedu yakapfava inoyera uye inoratidza kufamba kwechokwadi kana kutama kwe rotor pairi kutenderera iyo inopa nzira yakavakirwa-mukati yekusimbisa chokwadi chokuti muchina uri kupindura zvakanaka uye rotor yakaenzana zvakanaka.
Kubatsira kukuru kwemichina yakapfava ndeyekuti inowanzove yakawanda.Vanokwanisa kubata huwandu hwakawanda hwehuremu hwe rotor pane imwe saizi yemuchina.Hapana hwaro hwakakosha hunodiwa pakuvharisa uye muchina unogona kufambiswa pasina kuwana re-calibration kubva kune nyanzvi.
Michina yekuyeresa yakapfava, semichina yakaoma, inogona kuenzanisa marotor mazhinji akatwasuka.Nekudaro, kuenzanirana kweiyo overhung rotor kunoda kushandiswa kweiyo yakaipa mutoro inobata-pasi yekunamatira chidimbu.
Mufananidzo uri pamusoro unoratidza muchina wakapfava wekuenzanisa.Cherechedza kuti kutaridzika kwegadziriro yekutakura kunobvumira kuti pendulum idzoke shure uye mberi ne rotor.Iko kutamiswa kunorekodhwa neiyo vibration sensor uye gare gare inoshandiswa kuverenga iyo isingaenzaniswi iripo.
Yakaoma Bearing Bancing Machines
Michina yekuyera yakaoma ine zvitsigiro zvebasa rakaoma uye inotsamira pamagetsi akaomarara kududzira kuzunguzika.Izvi zvinoda hwaro hombe, hwakasimba apo dzinofanirwa kugadzikwa zvachose uye dzakagadziriswa panzvimbo nemugadziri.Dzidziso iri shure kwegadziriro iyi yekuenzanisa ndeyokuti rotor inomanikidzwa zvakakwana uye masimba ayo rotor anoisa pazvitsigiro anoyerwa.Background vibration kubva kumakina ari padyo kana chiitiko pauriri hwebasa chinogona kukanganisa mhedzisiro.Kazhinji, michina yakaoma-inotakura inoshandiswa mukugadzira mashandiro ekugadzira uko kunodiwa nguva yekukurumidza kutenderera.
Kubatsira kukuru kumichina yakaoma-inotakura ndeyekuti ivo vanowanzopa kukurumidza kusaenzana kuverenga, iyo inobatsira mukumhanya kwekugadzira kuenzanisa.
Chinhu chinodzikamisa chemichina yakaoma-inotakura ndiyo inodiwa kuenzanisa kumhanya kwe rotor panguva yekuyedzwa.Nemhaka yokuti muchina wacho unoyera simba risina kuenzana re rotor inotenderera, rotor inofanira kupeperetswa nekumhanya kukuru kuti ibudise simba rakakwana kuti rionekwe nekurembera kwakasimba.
Chikwapuro
Zvisinei kuti ndeupi muchina wakachinjika wekuenzanisa wakashandiswa, kuongororwa kweshamhu kungave kuri madikanwa kana uchienzanisa marefu, matete anotenderera, kana mamwe anochinjika rotor.Chikwapuro chiyero che deformation kana kukotama kwe rotor inoshanduka.Kana iwe uchifungidzira kuti ungangoda kuyera chikwapuro, tarisa nerutsigiro rwedu rwehunyanzvi uye isu tichaona kana chikwapuro chiratidzo chakakosha pachikumbiro chako.
