ISO 8434-2 thiab SAE J514 yog txawv txheem rau tib yam khoom: hydraulic tub fittings nrog 37 degree flared thiab flareless hom connector kawg, kuj hu ua jic hydraulic fittings.
ISO 8434 raws li Tebchaws Asmeskas cov qauv ANSI / SAE J514 [1]. Cov xov rau 37 ° flared
kev sib txuas yog sib sau ua ke nta raws li ISO 263. Cov ntiv tau ntab tsis tau hloov mus rau metric threads raws li ISO 261 kom cov neeg siv sib txuas ua ke nrog qhov International Standard los siv rau hauv cov ntawv uas twb muaj lawm uas tsis tau hloov txoj kev xa mus rau lub raj lossis lub rooj sib txuas ua ke. Yog li, nws kuj hu ua UNF hydraulic fittings.
ISO 8434-2 yog hlau txuas rau lub hwj chim ua kua thiab kev siv dav - Qhov 2: 37 ° flared connectors. Nws tseem yog ISO hydraulic fittings.
SAE J514 yog Hydraulic Tube Fittings J514_201201, kuj yog SAE hydraulic fittings.
ISO 8434-2 qhia txog kev tsim dav thiab kev loj hlob rau kev tsim thiab kev ua ntawm 37 ° flared connectors uas tsim nyog rau siv nrog ferrous thiab non-ferrous tubes nrog sab nraud diameters los ntawm 6 mm mus rau 50,8 mm, koog. Cov connectors no yog siv rau cov kua hluav taws xob thiab cov ntawv siv dav dav hauv cov kev txwv ntawm qhov siab thiab qhov ntsuas tau teev nyob rau ntu ntawm ISO 8434.
Lawv tau npaj rau txoj kev txuas ntawm cov raj thiab hose fittings mus rau ports raws li ISO 6149-1, ISO 1179-1, ISO 9974-1 thiab ISO 11926-1. (Saib ISO 12151-5 rau kev sib txuas lus hose haum xeeb.)
SAE J514 Txheem yog siv cov kev dav dav thiab dav rau 37 degree flared thiab flareless hom hydraulic tube fittings thiab O-ring plugs. Kuj muaj cov yeeb nkab fittings thiab adapter koom haum siv rau hauv nrog cov raj fittings. Cov fittings no yog npaj rau kev ua tiav hauv hydraulic systems rau cov khoom siv thiab cov khoom lag luam.
Cov fittings no muaj peev xwm muab kev tsis pom kev, tag nrho kev sib txuas hauv hydraulic systems khiav hauj lwm ntawm kev ua haujlwm
Tus txheej txheem SAE J514 muab faib ua 6 seem raws li nram no:
Nqe Seem 1-37 Flare Tube Fittings
Ntu 2-Flarless Tube Fittings
Ntu 3-O-Nplhaib Plugs (rau O-Ring Ports saib SAE J1926)
Tshooj 4-Hydraulic Yeeb Kev Fittings (yav tas los SAE J926)
Tshooj 5-Cov Neeg Pab Neeg Sib Sau (yav tas los hauv SAE J516)
Tshooj 6-Ntxhais Ntsuas Cov Ntaos Xam Ntawm Ntev
