Kodi mungasankhe bwanji chotengera cha pansi pa madzi?

Pali lingaliro lolakwika lofala lakuti ma bearing onse osagwira dzimbiri ndi oyenera kugwiritsidwa ntchito pansi pa madzi, koma sizili choncho. Maloboti apansi pa madzi, ma drone, ma propeller shafts ndi ma conveyor olowa pansi pa madzi onse amafunikira kuganizira za kapangidwe kake ndi ma bearing apadera. Ndi zipangizo ziti zogwirira ntchito zomwe zili zoyenera kugwiritsidwa ntchito pansi pa madzi.

Ma bearing ena osagwira dzimbiri amatha kugwira ntchito akakumana ndi madzi abwino, madzi amchere, nthunzi kapena mankhwala ena, koma si onse oyenera kugwiritsidwa ntchito pansi pa madzi mosalekeza. Kumiza bearing kwathunthu kungakhudze moyo wake, kutengera ndi zinthu zomwe wapangidwa nazo. Mwachitsanzo, ma bearing achitsulo chosapanga dzimbiri a grade 440. Amalimbana kwambiri ndi madzi abwino komanso mankhwala ofooka, koma akaikidwa m'madzi amchere kapena kumizidwa kwathunthu, amawononga msanga.

Maberiya nthawi zambiri amalephera kugwira ntchito msanga chifukwa cha dzimbiri, kulephera kwa mafuta kapena kuipitsidwa. Ngati beriya si yoyenera kugwiritsidwa ntchito pansi pa madzi kwa nthawi yayitali, madzi amatha kulowa mu gawolo ndikuwonjezera mavuto ofala awa. Ngati chisindikizo cha nyumba chasweka, madzi amatha kulowa mu dongosolo ndikuchepetsa mafuta, zomwe zimapangitsa kuti pakhale kukangana kwina komwe kungawononge gawo lonselo. Madzi amchere kapena mankhwala amathanso kuwononga beriya, zomwe zimapangitsa kuti gawolo likhale lokhalitsa. Chifukwa chake sankhani beriya ya pansi pa madzi muyenera kuganizira momwe beriya imagwiritsidwira ntchito komanso malo omwe ikugwiritsidwa ntchito kuti muwonetsetse kuti zida zawo sizikuwonongeka mwadzidzidzi ndikupangitsa kuti pakhale nthawi yokwera mtengo.

 

Kusankha mayendedwe oyenera

Pali mitundu yambiri ya ma bearing omwe ndi oyenera kumizidwa m'madzi, koma kusankha bearing yoyenera kugwiritsa ntchito ndikofunikira kwambiri.

Ma berea a CeramicSizimakhudzidwa ndi madzi amchere, choncho zimagwiritsidwa ntchito poyendetsa ndege zopanda mpweya pansi pa madzi m'malo operekera mphamvu kunyanja. Zipangizo za Zirconium dioxide kapena silicon nitride zimakhala zolimba kwambiri ndipo zimatha kupirira katundu wambiri womwe ungafunike mu ma propellor kapena ma conveyor apansi pa madzi.

Mabeya apulasitikiKomanso zimalimbana ndi dzimbiri kwambiri ndi madzi abwino komanso amchere ndipo zimatha kugwira ntchito bwino zikamizidwa mokwanira. Njira zina zapulasitiki ndi njira yotsika mtengo ndipo zimakhala ndi kukangana kochepa, ngakhale kuti mphamvu yonyamula katundu ndi yotsika poyerekeza ndi zitsulo kapena mabearing a ceramic.

316mabeya achitsulo chosapanga dzimbiriImagwira ntchito bwino kwambiri m'madzi abwino popanda kuwononga komanso kutentha kwambiri, kotero ingagwiritsidwe ntchito pa ntchito zochepa komanso liwiro m'makampani a za m'madzi, monga shaft ya propellor. Bearing ingathenso kupirira kuviikidwa m'madzi amchere ngati pali madzi oyenda bwino pamwamba pa bearing kuti ipereke mpweya wofunikira kuti iteteze dzimbiri.

Kuyika ndalama pa mafuta oyenera kudzaonetsetsa kuti mphamvu ya bearing ikupitirirabe. Mafuta osalowa madzi amathanso kuwonjezeredwa, kotero mafuta sachepetsedwa ndi kukhudzana ndi madzi.Si ma bearing onse olimbana ndi dzimbiri omwe ndi oyenera kugwiritsidwa ntchito nthawi yayitali pansi pa madzi, choncho sankhani ma bearing oyenera, monga ceramic, pulasitiki kapena zitsulo zina, zomwe zidzaonetsetsa kuti zinthuzo zimakhala ndi moyo wautali, popanda kufunikira kusintha ma bearing owonongeka kapena odzimbidwa nthawi zonse.Sankhani mikhalidwe yosiyanasiyana yomwe bearing ingathe kupirira zimathandiza kukonza magwiridwe antchito ndikuchepetsa mtengo wonse wa zida zosinthira.
