HG/T 20613 Chivundikiro cha ulusi wonse

Chidutswa cha ulusi wonse: ndi mtundu wa kufalikira kwa ulusi pamwamba pa boluti yonse, ndipo maboluti okhala ndi mitu iwiri kumapeto onse awiri ndi chiyambi cha ulusi, pakati pawo pamakhala gawo lopanda ulusi, malekezero awiri a ulusiwo mbali imodzi nawonso akhoza kubwezeretsedwa. Boluti yonse ndi yolumikizidwa, boluti iyi ndi yapamwamba kuposa maboluti a mutu wa hexagonal ndi mphamvu ya maboluti awiri a mutu, kuchuluka kwa ntchito, maboluti a hexagonal ndi ma stud awiri a mutu ndi maboluti amalonda, pogwiritsa ntchito mulingo wa magwiridwe antchito womwe wawonetsedwa. Ndipo ma stud odzaza ndi ulusi ndi mabolt apadera, kugwiritsa ntchito ma grade azinthu, kugwiritsa ntchito ma chemical installation, kugwiritsa ntchito zinthu zina kuyenera kutsimikiziridwa ndi kapangidwe kake m'malo mwa HG/T20613-2009 chitsulo cha payipi chokhala ndi stud yodzaza ndi ulusi wofanana ndi M10, M12, M16, M20, M24, M27, M30, M33, M36 × 3, M39 × 3, M45 × 3 M52×4, M56×4, pamwamba pake pakhoza kukhala pakuda, Dacromet, hot-dip galvanized, Teflon ndi zina zotero.

Ntchito ya ma stud a ulusi wonse imaonekera makamaka m'mbali zotsatirazi:
1. Kulumikiza ndi kulumikiza: Ntchito yaikulu ya stud yokhala ndi ulusi wonse ndikulumikiza ndi kulumikiza zigawo ziwiri kapena zingapo. Zimathandiza kuti zikhale zolumikizana bwino pakati pa zigawo kudzera mu kukulunga ulusi, zomwe zimalepheretsa kumasuka kapena kulekanitsa. Kulumikizana kwamtunduwu sikuti ndi kosavuta komanso kodalirika kokha, komanso kosavuta kusokoneza, zomwe zimathandiza kuti zikhale zosavuta kusintha kapena kukonza ziwalo zina zikafunika.
2. Kutumiza mphamvu: Zidutswa zokhala ndi ulusi wokwanira zimatha kutumiza mphamvu kuchokera ku chinthu chimodzi kupita ku china. Mu chipangizo kapena kapangidwe ka makina, kusamutsa mphamvu kumeneku ndikofunikira kwambiri kuti pakhale kukhazikika ndi kugwira ntchito bwino kwa kapangidwe konse. Mphamvu yayikulu komanso kudalirika kwa zidutswa zokhala ndi ulusi wokwanira zimathandiza kuti zipirire mphamvu zazikulu ndi kupsinjika kuti zitsimikizire kuti kapangidwe konse kakugwira ntchito bwino.
3. Kusintha ndi Kuyika Malo: Popeza chivundikiro chathunthu chili ndi gawo lalitali la ulusi, chingagwiritsidwe ntchito ngati chosinthira. Pozungulira chivundikirocho, malo ogwirizana pakati pa zigawo ziwiri zolumikizira amatha kusinthidwa, motero kusintha ndi malo olondola a zida kapena kapangidwe kake. Kusinthaku kumapangitsa kuti zivundikiro zathunthu zikhale zothandiza pakugwiritsa ntchito komwe kumafunika kuwongolera bwino malo kapena ngodya ya gawo.
4. Kulumikiza kosavuta: Kapangidwe ka stud yokhala ndi ulusi wonse kumapangitsa kuti ntchito yolumikizira ikhale yosavuta kuposa zomangira zina. Gawo lalitali la stud limapangitsa kuti zikhale zosavuta kulumikiza ndi kuyika m'bowo, zomwe zimachepetsa zovuta ndi zolakwika zolumikizira. Izi zimathandiza kuwonjezera magwiridwe antchito a stud ndikuchepetsa ndalama zopangira.
