Hydraulic fittings yuav tsum tau txheeb xyuas los ntawm ob qho tib si xov thiab sealing nto. Kev ntsuas tsuas yog sab nraud txoj kab uas hla tuaj yeem ua rau muaj qhov sib tw tsis tseeb vim tias ntau lub xov tooj muaj qhov sib xws nominal ntau thiab tsawg. Siv qhov sib piv hauv qab no kom nqaim cov tsev neeg haum, tom qab ntawd paub meej tias qhov loj me tiv thaiv cov khoom kos duab thiab mating-port specification.

Yuav ua li cas txheeb xyuas qhov Unknown Hydraulic Fitting
Ntxuav lub fitting kom cov xov thiab sealing nto pom.
Txiav txim seb cov xov yog ncaj los yog tapered.
Ntsuas tus txiv neej xov sab nraud los yog poj niam xov hauv txoj kab uas hla nrog calipers.
Ntsuas lub suab suab nrog lub suab ntsuas. Paub meej seb lub ntsuas ntsuas yog metric lossis threads ib nti.
Tshawb xyuas qhov sealing nto: flare, cone, tiaj ntsej muag, O-ring, bonded foob los yog tapered xov.
Nco ntsoov seb qhov haum yog txiv neej, poj niam, swivel, bulkhead, luj tshib lossis flange.
Sib piv cov kev ntsuas nrog cov khoom siv kos duab lossis qauv.
Tsis txhob yuam kev sib txuas uas tshwm sim ze. Ib nrab xov kev koom tes tsis ua pov thawj kev sib raug zoo, thiab lub kaum sab xis sealing tsis raug tuaj yeem xau txawm tias cov xov sib dhos.
Feem ntau Hydraulic Fitting Identification yuam kev
Tsis meej pem BSPP nrog metric threads
Qee qhov sib npaug BSP thiab metric loj tuaj yeem tshwm sim zoo sib xws. Kos ob lub suab thiab sealing geometry. BSPP tsis txheeb xyuas ib txoj kev sib khi los ntawm nws tus kheej.
Kho NPT thiab BSPT raws li kev sib hloov
Ob leeg yog tapered yeeb nkab threads, tab sis lawv cov ntaub ntawv xov thiab pitches txawv. Lawv yuav tsum raug txheeb xyuas nyias.
Txheeb xyuas qhov haum ntawm xov ib leeg
Cov xov yuav muab cov khoom tuav tuav thaum lub foob tshwm sim ntawm lub khob hliav qab, flare, ntsej muag lossis O-ring. Ob qhov nta yuav tsum sib phim.
Tsis quav ntsej lub teeb thiab hnyav metric series
Metric 24-degree fittings tej zaum yuav yog cov sib txawv series. Paub meej tias lub raj loj, xov thiab lub khob hliav qab kev teeb tsa tiv thaiv cov duab kos.
Cov lus nug nquag
Yuav tsum ntsuas dab tsi los txheeb xyuas qhov hydraulic haum?
Ntsuas xov txoj kab uas hla thiab suab, tom qab ntawd txheeb xyuas qhov sealing nto, haum orientation thiab mating-port hom.
Ob lub fittings tuaj yeem ua ke tab sis siv cov ntsaws ruaj ruaj?
Yog lawm. Kev koom tes ntawm xov ib leeg tsis lees paub tias qhov chaw sib khi lossis cov qauv sib haum.
Qhov txawv ntawm ORFS thiab JIC yog dab tsi?
ORFS siv lub ntsej muag tiaj tus nrog O-ring; JIC siv lub rooj zaum 37-degree flare.
Yuav tsum xov sealant siv rau txhua qhov hydraulic haum?
Tsis yog. Sealant siv nyob ntawm qhov kev sib txuas tsim. Flare, cone, lub ntsej muag foob thiab O-ring kev sib txuas foob sab nraum cov xov thiab yuav tsum tau sib sau ua ke raws li lawv cov specifications.
Tseem tsis paub meej qhov haum koj muaj? Xa cov duab ntawm cov xov thiab sealing ntsej muag ua ke nrog caliper thiab pitch-gauge ntsuas. Ruihua tuaj yeem sib piv cov ntaub ntawv nrog nws cov khoom siv kos duab.
