Izi zitha kuchitika ngati kukangana kukuwonjezeka chifukwa cha mafuta osakwanira, katundu wambiri, kapena kugwira ntchito kwanthawi yayitali pa liwiro lokwera. Kutuluka kwamtundu ndi chizindikiro chodziwikiratu kuti chinthu chonyamula chikukumana ndi kupsinjika kwa kutentha, zomwe zingafooketse kapangidwe kake.
l Kununkhira kwa Acrid kapena Kuwotcha : Fungo lakuthwa, lopweteka likhoza kusonyeza kuti mafuta onyamula akuyaka kapena kuwonongeka chifukwa cha kutentha kwakukulu. Nthawi zina, fungo likhoza kubwera kuchokera kuzinthu zonyamula zokhazokha pamene zimayamba kunyozeka kapena kuchokera ku zigawo zapafupi zomwe zimakhudzidwa ndi kutentha.
Chifukwa Chake Ndikofunikira : Kusintha kwamtundu ndi kununkhira kumasonyeza kuti kubereka kukugwira ntchito pansi pa zovuta kwambiri, zomwe zingathe kufulumizitsa kuvala ndikupangitsa kuti zisawonongeke. Kutentha kwambiri kungathenso kuwononga zigawo zoyandikana nazo, monga zisindikizo, shafts, kapena nyumba, kuonjezera mtengo wokonza ndi nthawi yopuma.
Zochita : Ngati zadziwika kuti zasintha kapena fungo lanunkhira, nthawi yomweyo zimitsani injini ya spindle kuti isawonongeke. Yang'anani ma fani kuti muwone ngati akutenthedwa, yang'anani momwe mafuta alili (mwachitsanzo, kukhuthala, kuipitsidwa), ndikuwunika momwe amagwirira ntchito (mwachitsanzo, liwiro, katundu, makina ozizirira). Bwezerani mayendedwe owonongeka ndikuwonjezeranso kapena kukweza mafuta kuti mupewe kubwereza.
Kuti muchepetse chiwopsezo cha kuwonongeka ndikukulitsa moyo wa ma spindle motors, lingalirani njira zabwino izi:
l Kukonza Nthawi Zonse : Gwiritsani ntchito ndondomeko yokonza nthawi zonse yomwe imaphatikizapo kufufuza kwa mafuta, kutsimikizira kulondola, ndi kuyendera. Gwiritsani ntchito mafuta apamwamba kwambiri ogwirizana ndi momwe spindle imagwirira ntchito.
l Vibration Monitoring : Ikani masensa akugwedezeka kapena gwiritsani ntchito zowunikira zonyamula kuti muzitha kuyang'anira kugwedezeka pakapita nthawi. Khazikitsani malire kuti muyambitse zidziwitso pamene kugwedezeka kupitilira malire ovomerezeka.
