Kodi kusankha chomangira choyenera? Ndi magawo ati omwe muyenera kudziwa?

Pankhani yosankha chomangira choyenera cha polojekiti yanu, pali zinthu zingapo zofunika kuziganizira. Kuchokera pamiyezo yazogulitsa ndi mafotokozedwe kupita ku zida, magiredi amphamvu, ndi chithandizo chapamwamba, chinthu chilichonse chimakhala ndi gawo lofunikira pakuzindikira magwiridwe antchito ndi kudalirika kwa chomangira. M'mawu awa, tikambirana mozama zankhani yosankha chomangira choyenera, ndikupereka chidziwitso cha akatswiri kuti akuthandizeni kupanga zisankho mwanzeru.

Miyezo ya Zamalonda ndi Zofotokozera

Gawo loyamba pakusankha chomangira choyenera ndikumvetsetsa milingo yamankhwala ndi mafotokozedwe omwe amagwiritsidwa ntchito. Kwa zomangira zomwe zimatsatira miyezo yeniyeni, monga DIN912 (zomangira za hexagon socket head), nambala yodziwika bwino imatha kuwonetsa bwino momwe amapangira komanso momwe amagwirira ntchito. Popanda miyezo yomveka bwino, zigawo zosagwirizana (zigawo zosagwirizana) zimafuna zojambula zatsatanetsatane kuti zisonyeze kukula ndi mawonekedwe awo. Padziko lonse lapansi, The German Institute for Standardization (DIN), The International Organisation for Standardization (ISO), Chinese national standards (GB), American National Standards Institute (ANSI) ndi Japanese Industrial Standards (JIS) onse ndi machitidwe okhudzidwa kwambiri.

Zomangamanga nthawi zambiri zimakhala ndi magawo awiri: ulusi wapakati ndi kutalika kwa screw. Metric ndi INCH ndi njira ziwiri zofotokozera. Zomangira za metric monga M4-0.7x8, pomwe M4 imayimira ulusi wakunja wa 4mm, 0.7 ndi phula, ndipo 8 ndi utali wa screw. Zomangira za INCH monga 6#-32*3/8, pomwe 6# imayimira ulusi wakunja kwake, 32 imayimira kuchuluka kwa ulusi pa inchi imodzi yautali wa ulusi, ndipo 3/8 ndi kutalika kwake.

Zipangizo

Zida za fasteners zimatsimikizira mphamvu zawo, kukana kwa dzimbiri ndi moyo wautumiki. Zida zodziwika bwino zimaphatikizapo chitsulo cha carbon, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, mkuwa, aluminiyamu, ndi zina zotero. Chitsulo cha carbon chingagawidwe kukhala chitsulo chochepa cha carbon, sing'anga mpweya wa carbon, mkulu wa carbon zitsulo ndi aloyi zitsulo, monga SCM435, 10B21, etc. Zitsulo zosapanga dzimbiri zodziwika bwino zikuphatikizapo SS302, SS304, SS316, SS316 ndi malo ake osiyana, ndi zina zotero. Zinthu monga corrosion resistance, mphamvu, ndi kulekerera kutentha ziyenera kuunika mosamala posankha zinthu zomangira chomangira chanu kuti zitsimikizire kuti zitha kupirira zomwe mukufuna.

Maphunziro a Mphamvu

Makamaka zomangira zitsulo za kaboni, nthawi zambiri zimagawidwa m'magulu osiyanasiyana amphamvu kutengera mphamvu zawo zolimba komanso mphamvu zokolola. Kumvetsetsa magiredi amphamvu ndikofunikira pakuwonetsetsa kuti cholumikizira chimatha kupirira katundu wofunikira popanda kulephera. Magiredi wamba akuphatikizapo 4.8, 5.8, 6.8, 8.8, 10.9, 12.9, etc. Zomangira zamphamvu kwambiri monga zinthu zomwe zili pamwamba pa 8.8 nthawi zambiri zimafunikira kutenthedwa ndikutenthedwa kuti zithandizire kukonza makina awo.

Chithandizo cha Pamwamba

Chithandizo chapamwamba makamaka ndichowonjezera kukana kwa dzimbiri ndi kukongola kwa zomangira. Njira zochizira zodziwika bwino zimaphatikizira kuyika kwakuda, galvanizing (monga buluu-zoyera zinki plating, zoyera zinc plating, etc.), plating mkuwa, nickel plating, chrome plating, ndi zina zotero. Pali zokometsera zachilengedwe komanso zosagwirizana ndi chilengedwe, ndipo makulidwe a zokutira adzakhudzanso zotsatira za mayeso opopera mchere. Kusankha njira yoyenera yochizira pamwamba molingana ndi malo ogwiritsira ntchito ndi zosowa kumatha kukulitsa moyo wautumiki wa zomangira.

Mwachidule, posankha zomangira, zinthu monga milingo ya malonda, mawonekedwe, zida, mphamvu, ndi chithandizo chapamwamba ziyenera kuganiziridwa mozama kuti zitsimikizire kuti zikukwaniritsa zofunikira zogwiritsidwa ntchito komanso kukhala ndi moyo wabwino komanso moyo wautali.
