Hydraulic fittings, hydraulic adapters, hydraulic adapters, compression fittings thiab tube txuas yog lub npe sib txawv, los ntawm txawv teb chaws rau tib txoj haujlwm ntawm hydraulic txuas. Yog li lawv muaj ntau cov qauv los ntawm SAE, BS, DIN, JIS thiab lwm yam, tab sis xyoo 1994 xyoo, Lub koom haum thoob ntiaj teb ntawm cov qauv ua ntau cov qauv hauv ISO 8434 series cov qauv. Tsis suav JIS cov qauv ntawm hydraulic fittings adatpers.
Ntawm no yog cov histroy ntawm hydraulic raj fittings, hydraulic adapters thiab cov khoom sib txuas, compression fittings thiab tube txuas:
Hydraulic yeeb fittings yog los ntawm AmericaSAE J514 Standardin xyoo 1950, muaj 37 degree flared thiab flareless hom hydraulic tub fittings thiab O-ring plugs. Kuj suav nrog cov yeeb nkab fittings thiab cov hloov kho rau cov tsev rau siv txuas nrog cov raj fittings. Cov fittings no yog npaj rau cov ntawv thov dav dav hauv cov tshuab hydraulic ntawm cov khoom lag luam thiab cov khoom lag luam khoom lag luam.Qhov qauv muaj feem xyuam yog SAE J1453, SAE J512, SAE J513, SAE J926, SAE J1926, SAE J516, SAE J518, SAE J1475 thiab lwm yam.
Hydraulic adatpors thiab cov khoom sib txuas yog los ntawm Askiv tus qauv BS 5200 hauv xyoo 1975, nws yog ua raws li cov ntawv thov xub thawj uas npaj los ntawm lub koom haum ntawm cov khoom siv hydraulic ua tsim nyob rau xyoo 1975. Nws yog rau txuas txhav thiab saj zawg zog tubing rau hydraulic kua hluav taws xob fais fab system Cheebtsam. Kaum plaub txoj kev hloov kho thiab tsib yam ntawm hose fittings, poj niam kawg haum hom.Qhov ntsig txog cov sawv yog BS 5380, BS 5327, BS 4586, BS 4518, BS 3832, BS 2779 thiab BS 1936.
Hlaws raj fittings nrog txiav nplhaib yog los ntawm lub teb chaws Yelemees Ermeto hauv xyoo 1930, DIN 2353 compression fittings thiab txuas, nrog stud xaus nrog DIN 3852-1, DIN 3852-2, DIN 3852-11. Nws yog qhov nplaim hluav taws kub tsis zoo hom kab txuas los txuas raj, hose sib dhos.
Xaus fittings thiab adapters rau hydraulic hose sib dhos los ntawm Nyiv JIS cov qauv hauv 1984 xyoo, nws yog nrov heev fittings hauv Japanese siv tshuab kev lag luam khoom lag luam. Cov qauv muaj feem xyuam yog JIS B2351, JIS B0202 thiab lwm yam.
Nws yog xim hlau txuas rau cov kua hluav taws xob thiab siv dav dav los ntawm International lub koom haum ntawm cov qauv hu ua ISO 8434 nyob rau xyoo 1994, nws yog lub hauv paus chaw haujlwm hauv Geneva, Switzerland, thiab ua haujlwm hauv 164 lub teb chaws, los txhawb kev tsim ntiaj teb kev lag luam thiab kev lag luam qauv. Yam ntsig txog ISO 8434 series hase -1, -2, -3, -4 thiab -6 santdards, npog Asmeskas cov qauv, Askiv tus qauv, Japanese cov qauv, Lub teb chaws Yelemees tus qauv, Suav cov qauv.
Tam sim no, peb feem ntau siv ISO 8434 series tus qauv ntawm cov raj xa hluav taws xob sib txuas rau kev sib tham nrog SAE J514, SAE J1453, DIN 2353, BS 5200 thiab lwm yam qauv fittings thiab adapters. Tab sis muaj qee cov qauv kev sib txawv tsis muaj kev hloov pauv tau nyob rau Nyiv xws li JIS B8363, JIS B2351 thiab lwm yam, Komastu hydraulic fittings, Caterpillar hydraulic fittings thiab lwm yam Tsim kom muaj cov qauv.
