Kunyamula ndi gawo lofunikira kwambiri pothandizira kuyendetsa bwino kwa mota, kuwonjezera pa kuwongolera njira zopangira, kapangidwe ndi kasinthidwe ka kutsogolera kwa mota ndikofunikira kwambiri, mongamota yoyimirira ndi mota yopingasaayenera kusankha ma bearing configuration osiyanasiyana, liwiro losiyana la injini liyeneranso kusankha ma bearing osiyanasiyana.
1 kasinthidwe kaMa berei a mota opingasa
Chotengera cha mpira ndi chotengera cha mzati ziyenera kugwiritsidwa ntchito momwe zingathere kumapeto onse awiri amota yopingasaPakadali pano, injini yaing'ono ndi yapakatikati ya m'nyumba yokhala ndi mipiringidzo iwiri imagwiritsa ntchito ma bearing a mpira oposa awiri, ngakhale opanga ena asintha zina ku malo olekerera a m'mimba mwake wa bearing mkati mwa msewu wolowera, kuti achepetse vuto la mpirawo kufinyidwa bearing ikatenthedwa. Komabe, chifukwa kuchuluka kwa expansion kwa bearing jekete ndi kwakukulu kuposa kwa zigawo zachitsulo zotayidwa zomwe zimanyamula bearing chamber - chivundikiro chakumapeto kapena bearing sleeve, ndipo kutentha kwa bearing jekete nakonso kuli kokwera, bearing jekete imatha kutsetsereka pang'ono mu bearing chamber kutentha kwa chipinda, koma bearing singathe kusuntha itatha kutenthedwa panthawi yogwira ntchito. Ichi ndiye chifukwa chachikulu chomwe nthawi yobearing imakhala yochepa komanso yosavuta kutentha ikagwiritsidwa ntchito ma bearing a mpira awiri. Pambuyo poyesa kukwera kwa kutentha kwa mota pogwiritsa ntchito ma bearing awiri a mpira, mota imayimitsidwa kuti iyeze kukwera kwa kutentha, ndipo nthawi zina bearing ya mota imayaka kachiwiri, chifukwa chake ndi chakuti kutseguka kwa bearing ya mpira sikungathe kupirira kufalikira kwa kutentha ndi kuzizira kwa rotor, ndipo jekete silingalowe m'chipinda choberekera, kotero kuti mpirawo ukhoza kunyamula mphamvu yayikulu ya axial yomwe imayambitsidwa ndi.
Ngati chotengera chimodzi cha mpira ndi chotengera chimodzi cha mzati chasankhidwa, mavuto omwe ali pamwambapa akhoza kupewedwa. Ndi fakitale yabwino kwambiri ya injini mu nambala ya chimango cha H560 muInjini yamagetsi amphamvu kwambiri ya 2-poleKuyambira kugwiritsa ntchito koyamba ma bearing awiri a mpira mpaka bearing ya mpira, bearing ya mzati, zotsatira zake zomaliza ntchito ndizabwino kwambiri. Kuphatikiza pa kusintha ma bearing malinga ndi nthawi yosamalira nthawi zonse, palibe cholakwika panthawi yogwira ntchito yanthawi zonse. Ndipo kutentha komwe kumayesedwa pa bearing ndi 20℃ yokha. Iyi ndi nthawi yoyamba yopambana yosinthira ma bearing awiri achikhalidwe kukhala bearing imodzi ya mpira ndi bearing imodzi ya ma mota a 2-pole ku China, ndipo pang'onopang'ono yakhala ikukwezedwa pama mota osaphulika.
Pofuna kuthetsa vuto la kutentha ndi phokoso pambuyo poti liwiro lochepa la ma bearing a mpira lasinthidwa ndi ma bearing a mzati, ma bearing a mzati wowala angagwiritsidwe ntchito, ndipo amaikidwa kumapeto kwa fan, kuzizira kuli bwino, ndipo phokoso la bearing lingalowenso m'madzi ndi phokoso la fan. Ngati mphamvu ya mota ya 2-pole ndi yayikulu, mtundu wa bearing ndi waukulu, ndipo ma bearing a mzati wowala ndi ovuta kukwaniritsa zofunikira za liwiro lochepa, mafuta onyamula akhoza kusinthidwa kukhala mafuta owonda.
2 Kapangidwe ka mabearing a mota oyima
Pamene mota yoyimirira ikugwiritsidwa ntchito kukoka pompo ya mbiya mu dongosolo la petrochemical, chifukwa cha mphamvu yokwera ya axial ya pompo ya mbiya ya magawo ambiri poyambira, pamodzi ndi zofunikira zoyendera, komanso kuti athetse kuwonongeka komwe kumachitika chifukwa cha kutentha kwa rotor kupita ku bearing, mota ya pompo ya mbiya yoyimirira (zonse ziwiri kapena zipilala zinayi), bearing ya pamwamba pa mota iyenera kusankhidwa ma bearing awiri a mzere umodzi wa centripetal thrust ball bearing. Ma bearing a mzati wa ma bearing otsika ayenera kusankhidwabe ngati mndandanda wopepuka. Pofuna kupewa kuwonongeka kwa ma bearing a mpira woponderezedwa, awiriwa ayenera kusankhidwa.oMa bearing ayenera kukhala ndi mphamvu yowonjezereka ya axial pa jekete la bearing. Kukula kwa mphamvuyo ndikuwonetsetsa kuti bearing isawonongeke ndi mphamvu yozungulira ya axial kuchokera kumapeto kwa shaft extension mpaka kumapeto osanyamula katundu panthawi yonyamula ndi kuyambitsa.
