Zomwe zimachititsa phokoso lamakina aasynchronous motor yamagawo atatu

Chifukwa chachikulu cha phokoso lamakina: Phokoso lamakina opangidwa ndi atatu-gawo asynchronous motormakamaka kubweretsa vuto phokoso. Pansi pa mphamvu yonyamula katundu, gawo lililonse la chonyamulira limapunduka, ndipo kupsinjika komwe kumachitika chifukwa cha kusinthika kozungulira kapena kugwedezeka kwamphamvu kwa ziwalo zopatsirana ndiye gwero la phokoso lake. Ngati chiwongolero cha radial kapena axial cha bearing chiri chochepa kwambiri, kukangana kozungulira kumawonjezeka, ndipo mphamvu yotulutsa zitsulo idzapangidwa panthawi yoyenda. Ngati kusiyana kuli kwakukulu kwambiri, sikudzangopangitsa kuti chiberekero chikhale chosagwirizana, komanso kusintha kusiyana kwa mpweya pakati pa stator ndi rotor, potero kumawonjezera phokoso, kukwera kwa kutentha ndi kugwedezeka. Chilolezo chonyamula ndi 8-15um, chomwe ndi chovuta kuyeza pamalowo ndipo chitha kuweruzidwa ndi kumverera kwamanja.

Posankha mayendedwe, muyenera kuganizira izi: (1) Kuchepetsa kusiyana komwe kumachitika chifukwa cha kugwirizana kwa tsinde ndi chivundikiro chomaliza. (2) Pogwira ntchito, kusiyana kwa kutentha pakati pa mphete zamkati ndi zakunja kumapangitsa kuti kusiyanako kusinthe. (3) Kusiyana pakati pa shaft ndi chivundikiro chomaliza kumasintha chifukwa cha ma coefficients osiyanasiyana okulitsa. Oveteredwa moyo wa kubala ndi 60000h, chifukwa ntchito molakwika ndi kukonza, kwenikweni ogwira ntchito moyo ndi 20-40% ya mtengo oveteredwa.

Mgwirizano pakati pa kunyamula ndi tsinde umatenga dzenje loyambira, kulolerana kwa mainchesi amkati mwa chigawocho ndi koyipa, ndipo mgwirizano ndi wolimba. Ma bearings ndi magazini amatha kuwonongeka mosavuta pakusonkhana popanda njira ndi zida zoyenera. Zonyamula ziyenera kuchotsedwa ndi chokoka chapadera.

Chigamulo cha kubereka phokoso:

1. Pamakhala mafuta ochulukirapo muzonyamula, padzakhala phokoso la nyundo yamadzi pakatikati ndi liwiro lotsika, komanso phokoso lopanda thovu losafanana pa liwiro lalikulu; Izi zimachitika chifukwa cha kukangana kwakukulu kwa mamolekyu amkati ndi akunja pansi pa mukubwadamuka wa mpira, zomwe zimapangitsa kuti mafuta asungunuke. Mafuta osungunuka kwambiri adawukhira pa ma windings a stator, kuletsa kuti zisazizire komanso kusokoneza kutchinjiriza kwake. Nthawi zambiri, lembani 2/3 ya malo onyamula ndi mafuta. Padzakhala phokoso pamene kubereka kulibe mafuta, ndipo padzakhala phokoso logwedeza ndi zizindikiro za kusuta pa liwiro lalikulu.

2. Pamene zonyansa mu mafuta zimabweretsedwa mu kubereka, kumveka kwa miyala yamkati ndi yosawerengeka kungapangidwe, zomwe zimayambitsidwa ndi kusakhazikika kwa malo a zonyansa zomwe zimayendetsedwa ndi mipira. Malinga ndi ziwerengero, kuipitsidwa kwamafuta kumakhala pafupifupi 30% ya zomwe zimayambitsa kuwonongeka kwamafuta.

3. Pali phokoso la "click" la periodic mkati mwa mayendedwe, ndipo ndizovuta kwambiri kutembenuza ndi dzanja. Ziyenera kuganiziridwa kuti pali kukokoloka kapena kung'ambika panjira yothamanga. Kumveka kwa "kutsamwitsa" kwapang'onopang'ono m'ma bearings, kuzungulira kwamanja kumatha kukhala ndi mawanga osakhazikika akufa, kuwonetsa mipira yosweka kapena zotengera mpira zowonongeka.

4. Pamene kumasuka kwa shaft ndi kubereka sikuli koopsa, padzakhala kukangana kwachitsulo kosalekeza. Pamene mphete yonyamula ikukwawa kumapeto kwa dzenje, imatulutsa phokoso lamphamvu komanso locheperako komanso kugwedezeka (komwe kumatha kuzimiririka pambuyo pokweza ma radial).
