Kodi ISO 8434-2 ndi chiyani ndipo mtundu waposachedwa kwambiri?
Mutu wa ISO 8434-2 ndi kulumikiza machubu azitsulo kuti azitha kugwiritsa ntchito mphamvu zamadzimadzi komanso kugwiritsa ntchito nthawi zonse -
Gawo 2: 37 ° zolumikizira zoyaka.
Kope loyamba linatulutsidwa mu 1994 ndipo linakonzedwa ndi Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, zolumikizira ndi zinthu zofanana ndi zigawo zake.
Mtundu waposachedwa ndi ISO 8434-2:2007, onani pansipa tsamba loyamba la ISO 8434-2 muyezo, ndi ulalo wochokera patsamba la ISO.

ISO 8434-2 idachokera ku SAE J514 (yomwe idatulutsidwa mu 1950) hydraulic tube fitting, yotchedwa 37 degree flared and flareless mitundu, zolumikizira zamtunduwu zimagwiritsidwa ntchito kwambiri ku America.
Kodi ISO 8434-2 imafotokoza chiyani?
ISO 8434-2 imatchula zofunikira zonse komanso zowoneka bwino pamapangidwe ndi magwiridwe antchito a zolumikizira zoyaka 37 ° zomwe ndizoyenera kugwiritsidwa ntchito ndi machubu achitsulo okhala ndi ma diameter akunja kuyambira 6 mm mpaka 50,8 mm, kuphatikiza.
Ngati mukufuna zinthu zina osati zitsulo, zili bwino ndipo chonde funsani makasitomala athu.
Kodi Wopambana ali ndi chinthu chogwirizana ndi ISO 8434-2?
Wopambana ayitaneni zolumikizira zamtunduwu monga adaputala ya JIC(Joint Industrial Council) kapena adapter kapena cholumikizira, ndipo zolumikizira zonse zomwe zafotokozedwa mu ISO 8434-2 zimapezeka kuchokera kwa Winner, ndipo J nthawi zambiri zimazindikirika kumapeto kwa JIC mu gawo la., monga. zolumikizira zowongoka zamagulu (1J), cholumikizira chigongono (1J9), cholumikizira cha T union (AJ), cholumikizira cha stud chokhala ndi ma stud kumapeto molingana ndi ISO 6149-3(1JH-N), cholumikizira bulkhead(6J), cholumikizira chowotcherera( 1JW), chigongono chozungulira chokhala ndi O-ring(2J9), ……Onani tsamba lamakasitomala kuti mumve zambiri, pali mitundu yopitilira 48 yomwe kasitomala angasankhe.[Ulalo wa kagulu kotsitsa]
Pansipa pali zithunzi za 37 ° zowotcha za JIC zolumikizira.

Wmkati 37°fcholumikizira cholumikizira cha JIC choyesedwa molingana ndi ISO 19879 komanso magwiridwe antchito apamwamba kuposa ISO 8434-2.
Chofunikira pakumaliza mu ISO 8434-2 ndi mayeso opopera mchere a 72 h osalowerera ndale molingana ndi ISO 9227 ndipo palibe dzimbiri lofiyira, mbali zopambana zimaposa zomwe ISO 8434-2 zimafunikira.
Below ndi mafotokozedwe a ISO ndi chithunzi choyesera chopopera mchere wopambana.
