Professional mechnical chisimbiso mugadziri yiwu chikuru chisimbiso rabha zvigadzirwa kambani
Zvimakanika zvisimbiso zvinoshanda mune yemvura svikiro kazhinji zvinovimba nemvura yemafirimu yakaumbwa neyemvura svikiro pakati pekupokana nzvimbo dzekufamba uye dzakamira mhete yekukodza. Naizvozvo, zvinodikanwa kuchengetedza iro remvura firimu pakati pekupokana nzvimbo kuona kugadzikana kushanda kwechimakanika chisimbiso uye kuwedzera hupenyu hwayo hwebasa.
Zvinoenderana nemamiriro akasiyana, iko kukakavadzana pakati pezvindori zvine simba uye zvimire zvesimbi zvemuchina zvichave zvinotevera:
(1) kukakavara kwakaoma:
Iko hakuna mvura inopinda inotsvedza yekukweshera pamusoro, saka hapana yemvura firimu, chete guruva, oxide rukoko uye adsorbed gasi mamorekuru. Kana iyo mhete inofamba uye inofamba ichimhanya, mhedzisiro ndeyekuti kukakavara pamusoro kuchapisa uye kusakara, zvichizoguma nekudonha.
(2) Boundary lubrication:
Kana kumanikidza kuri pakati pezvindori zvinofamba uye zvimire zvikawedzera kana kugona kwemvura kugadzira firimu remvura panzvimbo yekukweshera iri shoma, mvura yacho inosvinwa kunze kwemukana. Nekuti iyo yepamusoro haina kunyatsoti sandara, asi isina kuenzana, kune yekudyidzana kupfeka mune iyo bulge, nepo lubrication mashandiro emvura inochengetwa muzororo, zvichikonzera kumuganho lubrication. Iko kupfeka uye kupisa kwemuganho lubrication zvine mwero.
(3) Semi-mvura girisi:
Kune mvura mugomba rekutsvedza pamusoro, uye mutete wemvura firimu inochengetwa pakati penzvimbo dzekusangana, saka kudziya uye kupfeka mamiriro akanaka. Nekuti iyo firimu remvura pakati pemakenduru anofamba uye akamira ane kumanikidzwa kwepasirese panzvimbo yayo, kuvuza kwemvura kune mashoma.
(4) Yakazara lubrication yemvura:
Kana kumanikidza kuri pakati pemhete dzinofamba uye dzisingachinji kuri kukwana, uye gwanza richiwedzera, firimu remvura rinosimba, uye hapana kubatana kwakasimba panguva ino, saka hapana chinokakavara chinoitika. Nekudaro, mune ino kesi, mukaha uripakati pemhete inofamba uye iyo yakamira mhete yakakura, saka iyo yekuisa chisimbiso mhedzisiro haigone kuwanikwa uye kuvuza kwakakomba. Rudzi urwu rwemamiriro ezvinhu kazhinji hautenderwe mukushandisa kunoshanda (kunze kwechimakanika chisimbiso cheinodzorwa membrane).
Mazhinji emamiriro ekushanda pakati pemakenduru ane simba uye akasimba emakaniki echisimba ari mumuganho kugadzirwa uye kugadzirwa kwemvura-yemvura, uye girisi-yemvura girinhi inogona kuwana yakanakisa yekuisa chisimbiso pasi pemamiriro eiyo mashoma kukakavara coefficient, ndiko kuti, zvinogutsa kupfeka uye kupisa chizvarwa.
Kugadzira chisimbiso chemakaniki chishande pasi pemamiriro akanaka ekuzora, zvinhu zvakaita senge zvemukati hunhu, kumanikidza, tembiricha uye kutsvedza nekumhanyisa zvinofanirwa kutariswa zvizere Nekudaro, kusarudza kumanikidza kwakakodzera pakati pemaringi anofamba uye emira, inonzwisisika lubrication chimiro uye nekuvandudza kukweshera kwepamusoro mhando yemitambo inofamba uye yakamira zvinhu zvakakoshawo kuita basa rinoshanda rechisimbiso.
Zvimiro zvinoverengeka zvekusimbisa lubrication
1. End kumeso eccentricity:
Muzhinji mechisimbiso zvemagetsi, pakati pechindori chinofamba, pakati penzvimbo yakamira mhete uye wepakati mutsetse we shaft ese ari munzira yakatwasuka. Kana kumagumo kumeso pakati peimwe yerin'i inofamba kana mhete yakamira ikaitwa kuti ibviswe kubva pakati wepakati pemubato neimwe nhambwe, iyo yekuyerera mvura inogona kuenderera ichiunzwa munzvimbo inotsvedza kana iyo mhete ichitenderedza kukodza.
Izvo zvinofanirwa kutaurwa kuti saizi ye eccentricity haifanire kunge yakanyanyisa kukura, kunyanya pakudzvinyirira kukuru, iko kusimba kunokonzera kusaenzana kumanikidza kumagumo kumeso uye kusakaenzana kupfeka. Kune zvisimbiso zvekumhanya zvakanyanya, hazvikurudzirwe kushandisa rin'i rinofamba seyese eccentric, zvikasadaro muchina unozunguzika nekuda kwechiyero chesimba re centrifugal.
2. Kugadzira kumeso kumugumo:
Izvo zvinorema kune yakakwira-kumanikidza uye epamusoro-mhini michina yekuchengetedza iyo firimu yemvura pakati pekupesana nzvimbo, iyo inowanzo kuparadzwa nekukakavara kupisa kunogadzirwa nemhepo yakakwira uye kumhanya kwazvo. Mune ino kesi, zvinonyanya kushanda kutora grooving kusimbisa lubrication. Ose ari maviri mhete inofamba uye iyo yekumira mhete inogona kutsemurwa, iyo inowanzo gadzirwa neyekupfeka-isingagadzirike zvinhu. Iyo yekumira mhete uye yakamira mhete haifaniwe kutsemurwa panguva imwe chete, nekuti izvi zvinoderedza iyo lubrication mhedzisiro. Kuitira kudzivirira tsvina kana kupfeka marara kuti asapinda munzvimbo yekukwesana zvakanyanya sezvinobvira, uye kuvhara mvura inoyerera mukati mecentrifugal force direction (kubuda mhando), iyo groove inofanira kuvhurwa pane iyo yekumira mhete kudzivirira tsvina kubva pakuunzwa mukati iko kukweshera pamusoro ne centrifugal simba. Pane zvinopesana, kana mvura ichiyerera ichipesana ne centrifugal simba (mukati kuyerera), iyo groove inofanira kuvhurwa pane inofamba ringi, uye simba re centrifugal rinobatsira kukanda tsvina kubva mugoronga.
Iwo ma grooves madiki pane iyo yekukwesana pamusoro akaenzana mativi, akaumbwa-wedge, kana mamwe maumbirwo. Groove haifanire kunge yakanyanyisa kana kunyanyisa kudzika, zvikasadaro kuvuza kunowedzera.
3.Static kumanikidza lubrication:
Iyo inonzi hydrostatic lubrication ndeyekuzivisa zvakananga iyo yakamanikidza lubricating mvura mune yekukwesana pamusoro kune lubrication. Iyo yakaunzwa lubricating mvura inopihwa nechero yakasarudzika sosi sosi, senge hydraulic pombi. Neichi chakamanikidzwa kuita lubricating fluid, iko kuyerera kwemushini mumushini kunopikiswa. Iyi fomu inowanzoidaidzwa kuti hydrostatic pressure chisimbiso.
Matanho anofanirwa kutorwa kumisikidza gasi firimu lubrication yemakaniki chisimbiso cheiyo gasi yepakati, senge kutora gasi static kumanikidza inodzorwa firimu mechina chisimbiso kana solid solid lubrication, ndiko kuti, kushandisa kuzvidzora-lubricating zvinhu seactuating mhete kana static mhete. Chero bedzi mamiriro ezvinhu achibvumidza, iyo gasi yepakati mamiriro inofanira kuchinjwa kuita emvura yepakati mamiriro zvakanyanya sezvazvinogona, izvo zviri nyore pakuzora nekuisa chisimbiso.
