Kutengera momwe amagwiritsidwira ntchito komanso momwe zinthu zilili zovuta, ma bushing odzipaka mafuta okha nthawi zambiri amafunika kusinthidwa zaka zitatu mpaka zisanu ndi ziwiri zilizonse. Makina apakatikati akagwiritsidwa ntchito mkati mwa liwiro ndi kutentha komwe kumayembekezeredwa, amakhala ndi moyo wautali. Kumbali inayi, zida zomwe nthawi zambiri zimakhala zodzaza kapena zomwe zimayikidwa kutentha kwambiri zimatha kutulutsa mafuta mwachangu, zomwe zimafunika kusinthidwa pafupipafupi.

3. Kodi ma bushing awa amafunikira zipangizo zinazake za shaft kuti agwire bwino ntchito?

Ma shaft olimba achitsulo okhala ndi kuuma kwa pamwamba pa 45 mpaka 50 HRC ndi kutha kwa pamwamba pa 0.4 mpaka 0.8 μm amagwira ntchito bwino pa matekinoloje onse awiri. Zipangizo zofewa za shaft zimapangitsa kuti ma bushings azitha msanga, ndipo malo ovuta kwambiri amachititsa kuti filimu yamafuta ikhale yovuta kupanga. Opanga amapereka malangizo atsatanetsatane ogwirizana omwe amalemba zinthu zabwino kwambiri za shaft ndi njira zochizira pamwamba zomwe angagwiritse ntchito kuti ma bearing akhale nthawi yayitali momwe angathere komanso asawonongeke msanga.

Gwirizanani ndi Epen pa Zofunikira Zanu Zodzipaka Mafuta

Kusankha kampani yoyenera yodzipangira mafuta kumakhudza mwachindunji momwe zida zanu zimagwirira ntchito komanso mtengo wake kuti zigwiritsidwe ntchito. Jiashan Epen Bearing Co., Ltd. imapanga mitundu yosiyanasiyana ya ma bearings odzaza mafuta komanso ophatikizidwa ndi graphite omwe amapangidwira ntchito zovuta zamafakitale. Tikudziwa zambiri za zitsulo ndipo titha kugwira ntchito ndi aluminiyamu bronze, manganese bronze, ndi ma alloys ena omwe amapangidwira katundu wanu ndi malo ozungulira. Magulu aukadaulo a Epen amachita kafukufuku wozama wa pulogalamu yanu kuti akuthandizeni kudziwa momwe mungagwirizanitsire ntchito zabwino za graphite ndi ukadaulo wodzazidwa ndi mafuta. Timapereka kukula kwa kabukhu ndi mayankho omwe amapangidwira kuti agwirizane ndi zosowa zenizeni za zida zanu. Mutha kulankhula ndi gulu lathu lothandizira mainjiniya pa epen@cnepen.cn za tsatanetsatane wa pulogalamu yanu ndikupeza malingaliro azinthu othandizidwa ndi zolemba zaukadaulo, nthawi yopikisana, komanso kutumiza kodalirika komwe kumasunga nthawi yanu yopangira.
