Chophimba cha nangula chotsatira chimatanthawuza kuti dzenje lowongoka litabowoleredwa mu gawo lapansi la konkire, dzenjelo limabwerezedwanso pansi pa dzenje, ndipo chibowocho chitatha kukonzanso ndikutsegula fungulo lotseguka la bawuti la nangula limapanga njira yolumikizirana kuti izindikire kugwirizana kwa pambuyo-nangula.
Bawuti yakumbuyo yamakina opangira nangula imapangidwa ndi screw, bellow casing, washer wathyathyathya, makina ochapira masika, nati, ndipo amapangidwa ndi chitsulo cha 5.8 grade, 8.8 grade chitsulo, 304 (A2-70)/316 (A4-80) chitsulo chosapanga dzimbiri ndi zida zina. Kuchiza pamwamba ndi electrogalvanizing (avareji ya zinki wosanjikiza makulidwe ＞ 5 μ m) , yogwiritsidwa ntchito kumalo wamba; Hot dip galvanizing (avareji nthaka wosanjikiza makulidwe> 45 μ m) , ntchito m'malo dzimbiri.
Kumbuyo kwa belled mechanical nangula bolt idzagwiritsidwa ntchito pazinthu zapansi monga konkire yosasweka / konkire yosweka, miyala yachilengedwe, ndi zina zotero, kukonza zigawo zomanga ndi katundu wambiri kapena kukhazikitsa zipangizo zolemera. Bawuti ya nangula yakumbuyo yakumbuyo imakhala yokhazikika komanso yoyimitsa bwino kwambiri pansi pa katundu wambiri, kugwedezeka kwamphamvu komanso kuchuluka kwamphamvu. Pambuyo potseka makina ndi kukhazikitsa, palibe chifukwa chodikirira nthawi yochiritsa kuti ntchito yomanga ikhale yabwino.
The ndondomeko mawotchi nangula bawuti kumbuyo kukula pansi ndi motere: choyamba, ntchito molunjika dzenje kubowola kubowola mabowo ndi kuya kwa diameters lolingana, ndiye ntchito yapadera pansi kutambasuka kubowola kugwedeza pansi kukulitsa pansi mu maenje mphero woboola pakati, ndiye ntchito mwaye blower kuti agwirizane dzenje mpaka kulibe fumbi kugunda pansi potsiriza kulibe fumbi kugunda pansi. bawuti kukulitsa pansi kuti amalize kuzika.
