Eaton Standard NB200 / NB300 yog cov khoom tseem ceeb ntawm American JIC 37 ° Triple-Lok hydraulic raj fittings, nrog rau kev faib tawm ntawm kev ua haujlwm kom ruaj khov thiab kev sib txuas:
NB200: Txiv ntseej - Hexagonal lub taub hau nrog cov xov sab hauv, feem ntau yog siv rau kev zawm thiab siv lub siab kom ruaj ntseg haum.
NB300: Lub tes tsho / Pem hauv ntej Ferrule - Ntiv nplhaib-zoo li tus ferrule nrog ib tug ntse txiav ntug; thaum nruj, nws tom rau hauv lub raj phab ntsa kom ua tiav kev ruaj ntseg sealing thiab tuav.
Txuj : Eaton / Aeroquip, ua raws li JIC B-1
Xov : UNF American xov zoo (xws li, 7/16-20, 1/2-20, 9/16-18, thiab lwm yam)
Khoom siv : Carbon steel (zinc-plated / dub oxide), stainless hlau 304/316
Core Functions :
Transmits torque thiab axially compresses lub tes tsho NB300
Koom nrog cov xov lub cev haum kom kho cov tubing kom ruaj khov
Tiv thaiv kom loosening thiab tiv thaiv kev co hauv qhov chaw ua haujlwm hnyav
Common Sizes (Inch) : Sib piv cov kab uas hla ntawm hydraulic raj, nrog cov lej loj sib xws rau cov raj specifications (ntau yam hauv cov lus sib piv hauv qab).
Txuj : Eaton Triple-Lok JIC 37 °
Structure : Ib leeg pem hauv ntej ferrule nrog sab hauv txiav ntug thiab sab nraud 37 ° cone (nrog JIC haum lub cev)
Khoom siv : High-carbon steel, hardened stainless hlau (rau hnav thiab corrosion kuj)
Txoj Cai Sealing :
Txiv ntseej zawm → thawb lub tes tsho NB300 rau pem hauv ntej
Sab nraud 37 ° cone mates nrog lub cev haum lub 37 ° cone → daim ntawv ntsej muag sealing
Internal txiav ntug tom rau hauv lub raj sab nrauv phab ntsa → ua tiav cov nyhuv ntawm kev tuav thiab radial sealing
Kev vibration-resistant thiab siab-siab ntsuas (txog li 40MPa)
Txoj Cai Sib Tw : NB300-XX yuav tsum phim NB200-XX ntawm tib qhov loj. Piv txwv li: 1/4' tube → NB200-04 Nut + NB300-04 Tes Tsho

Loj Matching: Ob tus lej kawg ntawm NB200 / NB300 qauv sib haum rau lub raj sab nraud (piv txwv li, 04 = 1/4', 06 = 3/8').
Kev xaiv cov khoom siv: carbon hlau rau kev ua haujlwm dav dav; stainless hlau 304/316 rau corrosive ib puag ncig (xws li, marine, tshuaj lom neeg kev lag luam).
Npaj lub raj: Xyuas kom lub raj kawg yog du, tsis muaj burr-dawb, thiab txiav vertically (tsis muaj bevel).
Sib dhos cov khoom: Ua ntej nruab NB200 txiv ntoo rau hauv lub raj, tom qab ntawd xaub lub tes tsho NB300 (txiav ntug ntawm lub cev haum).
Tighten: Tes-tighten lub txiv ntseej kom txog thaum nws sib cuag lub cev haum, ces siv ib tug ciaj ntswj tig 1 mus rau 1¼ lem (kho raws li lub raj loj).
Tshawb xyuas: Tom qab kev teeb tsa, xyuas tias lub tes tsho tau raug mob tag nrho rau hauv lub raj phab ntsa thiab tsis muaj qhov xau hauv qhov siab.
