Zvikonzero uye Mhinduro dzeKudedera Kwakasimba kweChinodedera
1, Eccentric vibration ye exciter
Iyo centrifugal simba inogadzirwa nehuremu hwe eccentric panguva yekushanda kweiyo vibration exciter inokotamisa iyo eccentric shaft, zvichikonzera kukanganisa kwemukati mhete uye mhete yekunze yebearing. Iyo eccentricity inoburitsa vibration inokonzerwa ne frequency kutenderera uye yayo harmonic frequencies.
Naizvozvo, iyo inertia simba uye inertia vaviri vanogadzirwa panguva yekushanda zvinokonzeresa simba rekuita uye kudedera kweiyo kutakura, kukuvadza yakagadzikana yekushanda mamiriro ekutakura uye zvimwe zvikamu, uye kugadzira yakakwira-frequency vibration. Kana iyo inotakura vibration frequency yevibrating screen exciter yakafanana neyechisikigo frequency yeimwe nhanho ye elastic vibration yemidziyo skrini bhokisi, inokonzeresa kuzunguzika kwakasimba kweiyo skrini bhokisi elastomer yezvivhitivhiti zvinodedera.
Ose ari maviri dhiraivha shaft uye inofambiswa shaft masisitimu ekutakura ane resonance frequency yeimwe kukosha. Kana mamwe mafambiro anonakidza ari pedyo neiyo resonance frequency, resonance inoitika. Mukuwedzera, nekuda kwekuvapo kwe centrifugal inertial simba mu eccentricity, kukotama vibration kuchaitika. Kana iyo yekumhanyisa iri padyo neiyo yakakosha kukosha, bending resonance ichaitika.
2, Radial clearance yekubereka
Mhedzisiro yekubereka yebvunzo ye shale shaker inoratidza kuti idiki kana yakakura kwazvo radial clearance inokonzeresa kudedera kweiyo inotakura system. Kana iyo radial clearance ikanyanya kudiki, inokonzeresa kudengenyeka kwepamusoro-frequency; Kana iyo radial clearance yakawandisa, inokonzeresa yakaderera-frequency vibration.
Kana iyo radial clearance yakakura kwazvo, iyo radial yakasikwa frequency yeiyo inotakura elastic system ichaderedzwa, uye resonance ichaitika nyore, iyo inoburitsa yakakura yakaderera-frequency vibration. Naizvozvo, iyo radial clearance yakakura, iyo inoita kuti kubereka kuzununguke mupassband.
3、 Geometric kururama kwekubereka
Kana simba rinonakidza rechidzitiro chinodedera rakakura zvakanyanya, bearing rinova nesimba guru kwazvo reradial, saka kudedera kwakasimba kuchaitika. Kana nzira yemujaho, kunyanya kutenderera pamusoro pechinhu chinotenderedza, iine simba guru pakudedera kwebearing, kufamba kwepakati pechinhu chinotenderedza nekeji uye pamusoro pemhete dzemukati nedzekunze kunokonzera kudedera kwebearing. Saka, kuderedza kudedera kwebearing, kunyatsogadzirisa kwepamusoro pechinhu chinotenderedza kunofanira kutanga kwavandudzwa.
4. Kutakura friction uye lubrication
Kubereka ndiyo huru vibration sosi iyo yakaoma kudzora kune shale shaker. Sezvo shale shaker inoshanda nesimba guru rekusimudzira, kutakura kunotambura nemasimba makuru eradial. Kana iyo lubrication isina kunaka, pachava nekukwesha kukuru, izvo zvichaita kuti tembiricha yekutakura ikwire nekukurumidza uye yakakwira zvakanyanya, uye kuwedzera kwemafuta kwakakura zvakanyanya, izvo zvichaderedza zvakanyanya kubviswa kweradial, uyezve kuwedzera kukwesha, izvo zvinowedzera kuwedzera tembiricha.
5. Kuiswa kwemhete yekunze uye gomba rinotsigira
Kana iyo kukwana kwakasimba, inomanikidza nzira yekumisikidza, kuwedzera chikanganiso chechimiro, uye kutungamira mukuwedzera vibrate. Kusununguka kwakasununguka kunogona kuita kuti firimu remafuta mumvumo rivhare. Kana zvinhu zvemukati zvemaburi anotsigira emhete yekunze uye chigaro chekutakura chakanyatsosiyana, kunyanya kana zvindori zvinonyorovesa rabha zvakaiswa pakati pavo, vibration kutapurirana kuchadziviswa.
