Tsis tas li ntawd, ceev faj nrog kev siv cov sealants ntawm cov yeeb nkab threads. Yog tias qee qhov sealant nkag mus rau hauv hydraulic system, nws tuaj yeem txhaws thiab ua rau lwm yam teeb meem.
JIC 37 degree Flare Fittings
Tubing kev sib txuas yog tsim nrog lub khob hliav qab, flare thiab O-ring connectors, thiab ib qho ntawm feem ntau siv yog JIC 37 degree flare haum, tshwj xeeb tshaj yog nyob rau hauv high-pressure applications. Txawm hais tias kev lag luam feem ntau lees txais tias JIC 37 degree flare fittings yog rov siv tau, lawv yuav tsis yog ib txwm ntseeg tau thaum rov siv dua. Qhov tseeb, JIC 37 degree flare haum rau saum Cov Lus Nug Tshaj Lij Tshaj Lij rau kev sib sau ua ke.
JIC 37 degree flare fittings muaj lub khob hliav qab ntawm tus poj niam adapter thiab flare ntawm tus txiv neej adapter. Lub khob hliav qab thiab lub rooj zaum flare rau ib leeg los tsim kom muaj kev sib txuas ua tiav ntawm tus txiv neej thiab poj niam haum. Tab sis, txhua zaus cov hlau-rau-hlau foob raug tsim, lub khob hliav qab thiab nplaim tawg ntau dua, ua rau cov khoom ua haujlwm txias. Qhov tshwm sim yog cov hlau hnyav dua, uas ua rau txhua qhov kev sib dhos tom ntej nyuaj thiab teeb meem ntawm ob sab pem hauv ntej: lub foob tawg thiab txo qis vim qhov ntswg ntau dhau.
