Motor vibration case sharing

Shamwari yakanaka yaMai Shen, akwegura W, anoshanda mune imwe shopu yokugadziridza.Nekuda kweiyo mikuru yakafanana, iwo maviri anowanzo aine mimwe misoro pamamotor ane mhosva.Amai Shen vanewo ropafadzo nemukana wekuona mhosva dzemotokari.Chikwata chavo chakaita H355 2P 280kW yakakandwa aluminium rotor mota.Mutengi akataura kuti pakanga paine kuzunguzika kuri pachena panguva yekugadzirisa, uye kutsiva kutakura hakuna kushanda.Nekudaro, nekuda kwenguva inodiwa yekudziya, mugadziri anogona chete kutendeukira kune iri pedyo kugadzirisa unit., inova iyo unit iyo W yekare iripo.

Yakasanganiswa nematanho anotorwa nemutengi, shaft inogona kuvhomorwa nemaoko panguva ye disassembly uye kugadzirisa.Saizi yesimbi core shaft gomba uye shaft yemota rotor core inowonekwa.Kukwana pakati pezviviri izvi kujeka kwakakodzera, uye iyo shoma clearance ndeye 0.08mm kune rimwe divi.Chikwata chekugadzirisa chakapa mhinduro padambudziko kumugadziri, uye vakaita ongororo yakazara pakuitika kwedambudziko.Nekuda kweshamwari yangu yakanaka yekare W, Ms. Shen vane nzwisiso shoma yemaitiro edambudziko, pamwe nekuongorora kwangu pachangu dambudziko, ini ndichagovana nyaya iyi newe.

●Kune circumferential scratches mu circumferential direction ye shaft, asi haikonzeri zvakanyanya kukanganisa pane yekutanga machined surface.Zvinoenderana nedata rakapihwa nemugadziri, hapana dambudziko rakakura nehukuru hwekugadzira shaft, uyedhayamita yegomba re shaft zviri pachena kunze kwekushivirira.

● Kana ukuru hwegomba re rotor shaft yakakura kwazvo, inogona kuwanikwa kuti gomba re shaft kune imwe mugumo rakakuvadzwa zvakanyanya, uye pane zviratidzo zvakajeka zvehari pasi pamucheto wesimbi;

● Pane zvakajeka zviratidzo zvekukwenya kwechokwadi mune axial kutungamira kwegomba re shaft, iyo inofanirwa kukonzerwa nekubvisa nzira ye shaft;

● Pamusoro pe rotor yakasviba zvachose, iyo iri pachena muhurumende mushure mekupisa;ma rotor slots akachekwa zvakakomba.

Kubva pakuongororwa, zvakaonekwa kuti rotor shaft yakanga yapisa uye yakabviswa.Iyi nzira yakaita kuti dhayamita yegomba re shaft ikuvadzwe uye iwedzere.Mushure mekunge shaft yakajairwa yakaiswa zvakare, rotor yaive centrifugal panguva yekushanda kwemota, uye periodic uye isiri-periodic kusangana neshaft yakaitika.Kuvhunduka, uye mhedzisiro ndeye mota vibration.Dambudziko iri rinogona kuitika muchikamu chekuyedza chemota, kana muchikamu chekushandisa chemota, asi iko kurova kunouraya kumota pachayo.

Kana iyo rotor yemota isingakwanise kuzadzisa zviyero zvekudzora zvinodikanwa panguva yesimba rekuenzanisa maitiro, tarisa rotor yematambudziko ebhiza, bvisa shaft kuburikidza nemafuta-yakazara kutonhora kudzvanya, wobva waisa mu calibration chishandiso (zvakafananakune shaft yenhema) kugadzira iyo yakakandwa aluminium rotor musimboti.Mushure mekupedzwa, shaft uye musimboti wesimbi zvakasungwa zvakasimba uye hazvigone kubviswa, uye shaft inobviswa nechisimba nekutsikirira kunotonhora, izvo zvinozopedzisira zvakonzera kukuvara kwakanyanya uye deformation yesimbi yepakati gomba, uye dhayamita yegomba. zvakare zvakakomba nekuda kwekushivirira;zvichikonzera kusviba kwe rotor Chikonzero ndechekuti shaft uye rotor zvinopisa panguva yekutanga kuumbwa.

Matambudziko akafanana anogona kusangana nevagadziri vemotokari vakasiyana, asi maitiro ekugadzirisa dzimwe nguva anonetsa kudzora pane yakajairika kugadzirwa uye kugadzirisa maitiro, nekuti imwe neimwe nyaya ichave neyayo yega hunhu, asi nzira yekugadzirisa dambudziko iri inyaya yehunyanzvi uye tekinoroji. management.fusion inoshanda.
