Q: Dab tsi yog qhov zoo ntawm kev siv metric xov tom hom raj ntsaws?
A: Metric thread bite type tube plugs muaj ntau qhov zoo, suav nrog kev ntsuas meej, kev ua haujlwm siab sealing, durability, thiab compatibility nrog metric-based systems. Lawv kuj muab cov kev daws teeb meem zoo rau kev siv hydraulic.
Q: Yuav ua li cas koj tswj metric thread tom hom raj plugs?
A: Kev saib xyuas tsis tu ncua ntawm metric xov tom cov raj ntsaws nrog kev kuaj xyuas cov dej xau, corrosion, lossis puas. Yog tias pom muaj teeb meem, cov fittings yuav tsum tau kho lossis hloov tam sim ntawd. Tsis tas li ntawd, ua kom cov fittings huv si thiab tsis muaj cov khib nyiab yog qhov tseem ceeb kom ua haujlwm zoo.
Q: Qhov txawv ntawm JIC thiab ORF yog dab tsi?
A: Qhov txawv yog txoj kev ntawm txhua txoj hlua khi. Thaum lub JIC ntsaws ruaj ruaj ntawm cov hlau-rau-hlau flare, ORB ntsaws ruaj ruaj ntawm O-ring, uas muaj qhov zoo tshaj plaws tsis muaj kev sib txuas. Inch Compression: Lub nti compression haum yog ib hom kev haum rau hydraulic tubing thiab muaj cov hose tsis tshua muaj kev sib txuas rau cov qauv no.
Q: Qhov txawv ntawm NPT thiab ORFS yog dab tsi?
A: Xov Tsim: Lub ntsej muag foob (ORFS): Cov yam ntxwv los ntawm nws cov xov ncaj thiab lub ntsej muag O-ring tiaj tus uas ua kom muaj kev sib khi. NPT (National Yeeb Nkab Tapered): Nta tapered threads uas tsim lub foob los ntawm xov cuam tshuam, lub ntsiab lus ntawm threads deform me ntsis los tiv thaiv cov xau.
Q: Puas yog JIC haum rau NPT?
A: Tej zaum nws yuav ua tau kom xov zoo ib yam li txiv neej NPT fittings rau poj niam JIC plugs; txawm li cas los xij, qhov rov qab rooj plaub tsis tuaj yeem ua tau.
Q: JIC txhais li cas hauv hydraulic fittings?
