Hauv cov tshuab hydraulic, kev xaiv kom raug thiab nkag siab ntawm hydraulic haum xov hom yog qhov tseem ceeb rau kev ua kom tsis muaj kev sib txuas thiab kev ua haujlwm zoo.Kab lus no ua haujlwm raws li cov lus qhia dav dav rau hydraulic haum xov hom, npog cov qauv feem ntau, lawv cov yam ntxwv, thiab kev txiav txim siab rau kev teeb tsa thiab kev saib xyuas.
Tshawb nrhiav Hydraulic Fitting Thread Hom
Hydraulic haum xov hom xa mus rau cov qauv xov tshwj xeeb siv rau kev sib txuas cov khoom siv hydraulic.Cov xov no tso cai rau kev ruaj ntseg ntawm fittings rau hoses, li qub, lub tog raj kheej, thiab lwm yam hydraulic system.Nws yog ib qho tseem ceeb kom phim cov xov hom ntawm ib qho haum nrog cov xov zoo sib xws ntawm cov khoom siv kom ntseeg tau tias muaj kev ruaj ntseg thiab tsis muaj kev sib txuas.
Common Hydraulic Fitting Thread Standards
Muaj ntau ntau siv hydraulic haum xov qauv, nrog rau cov hauv qab no:
NPT (National yeeb nkab xov)
CovNPT xov homnrog rau tus qauv ASME B1.20.3 feem ntau yog siv nyob rau hauv North America thiab yog yus muaj los ntawm tapered threads.Nws nta ib tug txiv neej thiab poj niam xov uas maj mam nqaim, tsim ib lub foob los ntawm compressing cov tapered threads ua ke.NPT threads yog nrov rau lawv qhov yooj yim ntawm kev teeb tsa thiab feem ntau pom muaj nyob rau hauv cov ntawv thov uas muaj qhov nruab nrab hydraulic siab.
BSPP (British Standard Pipes Parallel)
CovBSPP xov hom, tseem hu ua G (BSP) lossis BSPF (British Standard Pipe Poj Niam) siv ISO 12151-6, yog siv dav hauv Tebchaws Europe thiab lwm thaj chaw.Tsis zoo li NPT xov, BSPP xov yog sib npaug, txhais tau tias lawv tsis taper.Cov xov no yuav tsum tau siv cov sealing washers los yog O-rings los tsim ib lub foob kaw ntom nti.BSPP fittings feem ntau siv rau hauv cov ntawv thov siab dua.
BSPT (British Standard Yeeb Nkab Tapered)
BSPT xov hom, tseem hu ua R (BSP) lossis BSPT (British Standard Pipe Taper) siv DIN2999 thiab DIN3858 tus qauv, zoo ib yam li NPT threads uas lawv tau tapered.BSPT threads, txawm li cas los xij, muaj lub kaum sab xis sib txawv thiab feem ntau siv rau hauv cov yeeb nkab me me.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias BSPT thiab NPT threads tsis hloov pauv tau, thiab siv cov xov tsis ncaj ncees tuaj yeem ua rau cov xau thiab kev sib txuas tsis raug.
JIC (Joint Industry Council)
JIC xov, tseem hu ua UNF (Unified National Fine) siv ISO 8434-2 thiab SAE_J514 cov qauv, yog dav siv nyob rau hauv hydraulic systems thiab feature ib tug 37-degree flare.Cov xov no muab kev ruaj ntseg thiab tsis muaj kev sib txuas los ntawm kev siv lub flare thiab lub foob hlau-rau-hlau.JIC fittings yog nrov nyob rau hauv high-pressure daim ntaub ntawv thiab paub txog lawv yooj yim los ua ke.
ORFS (O-Ring Lub ntsej muag foob)
ORFS xovhom siv O-ring los tsim ib lub foob ntawm qhov haum thiab cov khoom.Cov xov no muab kev tiv thaiv zoo heev rau cov xau thiab feem ntau siv hauv cov tshuab hydraulic siab.ORFS fittings paub txog lawv txoj kev ntseeg siab, yooj yim ntawm kev sib dhos, thiab ua haujlwm rau kev co.Cov khoom siv ORFS no siv ISO 8434-3.
Metric Xov
Metric threadsFeem ntau siv nyob rau hauv European thiab thoob ntiaj teb hydraulic systems.Lawv muaj qhov ncaj, sib luag tsim thiab ntsuas hauv millimeters.Metric threads muab kev sib raug zoo nrog ntau yam ntawm cov khoom thiab feem ntau pom muaj nyob rau hauv cov ntawv thov uas xav tau siab dua.Cov xov no ua raws li ISO 68-1, GB / T192, JIS B0205, GOST 9150, ASME B1.13M, thiab BS3643-1.
Xaiv txoj cai Hydraulic Fitting Xov Hom
Thaum xaiv qhov tsim nyog hydraulic haum xov hom, xav txog cov hauv qab no:
✅Cov Kev Xav Tau
Nkag siab txog qhov siab, qhov kub thiab txias, thiab qhov xav tau ntawm koj qhov hydraulic system los txiav txim siab hom xov zoo tshaj plaws.
✅Khoom Compatibility
Xyuas kom meej tias cov xov hom ntawm qhov haum haum rau cov xov hom ntawm cov khoom kom ntseeg tau tias muaj kev sib txuas zoo thiab ruaj ntseg.
