SAE J1475_201406 tus qauv yog rau cov Hose Haum Rau Cov Ntawv Nkag Rau Tubrog Nkoj.
SAE J1475 duav txog kev siv dav dav thiab kev ua haujlwm rau cov hydraulic hose fittings ntawm tus cwj pwm, hom, thiab cov chav kawm uas tau sau tseg hauv Tshooj 3 thiab siv ua ke nrog cov ntoo hauv cov ntaub ntawv sib txawv hauv cov ntaub ntawv. Daim ntawv no tsis tuaj yeem ua kom tiav cov neeg ua haujlwm ntawm cov hydraulic hose thiab hydraulic hose fittings. Kev sib haum xeeb yog lub luag haujlwm ntawm qhov chaw ua khoom siv hydraulic hose.

Hom kev SAE J1475 Fittings yuav tsum yog ib yam ntawm cov nram qab no: txiv neej dryseal xa xov, txiv neej SAE ncaj xov O-ring thawj, txiv neej 37 degree flared, poj niam 37 degree flared, txiv neej 45 degree flared, poj niam 45 degree flared, txiv neej tsis , poj niam tsis muaj ntsej muag, poj niam metric ncaj xov O-ring boss, lub ntsej muag muab khi, los yog 4-bolt cais flange sib txuas. Lub hom phom tuaj yeem muaj ntau tshaj ib hoob uas haum.
Cov khoom ntawm SAE J1475 fittings Rau cov pas tuav, kev zam txim, raj, thiab yeeb nkab, cov khoom yuav tsum yog hlau. Kev tawm nyob rau hauv 50 hli yuav tsum tsis pub tsawg tshaj 10%. Split flange clamp halves yuav tsum yog ntawm cov khoom siv ferrous nrog ib lub tensile zog ntawm tsawg kawg 31 0 N / hli 2 thiab ib tug elongation nyob rau hauv 50 mm ntawm tsis muaj tsawg tshaj li 6%. Castings yuav siv tau rau clamps thiab split flange clamp halves.
