Taw qhia rau Brass-PE Cov Kev Sib Txuas
Hauv cov tshuab tsheb thauj khoom, tshwj xeeb tshaj yog nyob hauv cov roj uas muaj chaw nyob, dej, thiab kev sib koom tes cua sov, tooj dag fittings feem ntau siv.
Polyethylene (PE) Cov kav dej, paub txog kev hloov pauv thiab xeb tsis kam, yog siv tau dav hauv cov kab ke no.
Txawm li cas los xij, kev sib txuas kev sib txuas ntawm tooj dag thiab PE cov khoom siv feem ntau ua rau sib txawv vim muaj kev sib txawv hauv kev nthuav dav, hluav taws xob nthuav dav, thiab tawv tawv.
Ua kom zoo rau kev sib khi ua tau zoo ntawm cov kev sib txuas no yog qhov tseem ceeb rau kev ua kom muaj kev cia siab ntev kom muaj kev nyab xeeb thiab kev nyab xeeb.
Cov khoom sib xyaw thiab cov teeb meem cuam tshuam
Tooj dag yog cov tawv me me me me, thaum PE yog ib lub thermoplastic nrog cov qis zog nyob rau hauv lub nra.
Thaum sib txuas ua ke, kev tsis sib xws hauv kev coj tus cwj pwm tuaj yeem ua rau muaj kev ntxhov siab lossis dej txias hauv PE.
Lub cev tsis txaus, thermal cycling, lossis kev co tej zaum yuav muaj kev sib luag.
Txhawm rau ua kom zoo tshaj plaws, interface tsim yuav tsum muaj nyiaj rauplawg expansion, tus cwj pwm nkag, thiab tshuaj lom neeg ruaj khov.
Kev siv ntawm elastomeric ntsaws ruaj ruaj lossis cov tshuab xauv cov qauv feem ntau tsim nyog kom haum rau cov kev sib txawv no.
Cov Hom Neeg Kho Tshuab Cov Qauv Sib Tham
Cov kev sib txuas sib txuas ib txwm poob rau ntau hom:
CATTression FittingsSiv cov noob txiv ntoo thiab cov ferrules
Ntxig Fittingsnrog barbed tooj dag xaus rau hauv pe
Threaded Adapter JointionsNrog cov gaskets lossis cov kab xev
Electro-fusion los yog hloov fittingsuas sib xyaw ua ke thiab cov thermal koom nrog
Txhua txoj hauv kev muaj qhov cuam tshuam tshwj xeeb rau kev sib khi, tshuab thauj khoom hloov, thiab ntev kev ncaj ncees.
Cov fittings tseem nyob twj ywm tshaj plaws, tab sis yuav tsum tau ua tib zoo saib xyuas torque tswj thiab lis kev txhim kho kom zoo.
Lub luag haujlwm ntawm Sealing ntsiab: O-Rings thiab Gaskets
Ib qho tseem ceeb hauv kev sib khi ua kom zoo yog qhov tsim thiab xaiv cov ntsiab ntawm sealing.
O-rings (Feem ntau EPDM, NBR, lossis FKM) tau muab tso rau hauv tus tooj dag fitting los tsim radial lossis axial ntsaws ruaj ruaj.
Qhov zawj puab, qhov tob, thiab nto yuav tsum ua raws li cov qauv haujlwm thoob ntiaj teb (piv txwv li, iso 3601).
Kev xaiv cov khoom siv nyob ntawm daim ntawv thov kev mob - ntsuas kub, siab, ua kua tau sib xws.
Dual Sealing Systems (piv txwv li, ib qho O-Ring nrog ib qho thaub qab gasket) tau siv nyob rau hauv cov txheej txheem tseem ceeb.
Thermal nthuav dav thiab kev ntxhov siab kom rov qab txiav txim siab
PE kav dej nthuav dav ntau dua tooj dag nyob rau hauv thermal kev ntxhov siab (coefficient ~ 10x siab dua).
Thaum nthuav tawm qhov kub hloov, qhov sib koom tes yuav tsum cia rau kev txav chaw tsis muaj kev sib cuam tshuam lub foob.
Foob qauv tsim nyog yuav tsum muajFloating Support, Kev tuav txoj cai, lossisKev Kho Mob Rau Yus Tus Kheej.
Kev ntxhov siab so nyob rau hauv PE, tshwj xeeb tshaj yog nyob rau hauv tas li thauj, yuav txo lub zog sib khi raws sijhawm.
Siv load-them nqi tsim qauv zoo li lub caij nplooj ntoo hlav hluav taws xob lossis cov nqaj hlau sib dhos-pab tswj kev ncaj ncees.
Deg tas, thev naus laus zis thiab muaj kev ntsuas
Qhov chaw zoo thiab qhov ruaj khov haum ntawm tooj dag thiab PE feem cuam tshuam zoo heev cuam tshuam kev ntseeg tau.
Tooj dag cov kev sib tiv tauj cov chaw yuav tsum yog du (ra tsawg dua los yog sib npaug rau 1.6 μm) tiv thaiv o-ntiv nplhaib ua paug.
Tev yuav tsum tau nruj kom tiv thaiv qhov khoob tsis tau xoob txaus kom ua kom sib dhos.
Precision machining ntawm grooves thiab sealing rooj yog qhov tseem ceeb.

Kev Ntsuas Cov Qauv rau Foob optimization
Txhawm rau xyuas cov kev ua tau zoo, kev sib xyaw ua ke yuav tsum tau siv:
Hydrostatic siab sim(feem ntau 1.5 × kev ua haujlwm siab)
Kev caij tsheb kauj vab thermallos ntawm -20℃rau 80 degree
Rub tawm-tawm kev xeemRau Axial Retention Zog
Lub sij hawm ntev nkag thiab kev ntsuam xyuas sonyob rau hauv lub siab sab hauv
Helium weaksrau cov tshuab nqus yuav tsum ua kom nruj rau 10⁻⁶ Mbargers. S
Cov ntaub ntawv xeem pab kho cov zawv zawv cable geometry, cov khoom xaiv, thiab cov khoom siv torque rau cov sib txuas.
Daim Ntawv Thov Cov Lus Thov Cov Lus Taw Qhia thiab Tsim Txhim Kho
Cov lus teb los ntawm cov teb kev sib txuas yog qhov tseem ceeb rau kev txhim kho txuas ntxiv.
Cov ntsiab lus tsis ua hauj lwm xws li:
O-ntiv nplhaib extrusion vim over-compression
Pe Yeeb Nkab deformation ntawm Siab Torque
Sealing tsis ua haujlwm los ntawm thermal cycling lossis UV kis
Txhim kho cov tswv yim muaj xws li:
Kev sivanti-twist yam ntxwv
Ntxivkev txwv tsis pub muaj compression
Ua ntaub ntawv thovUa ntej lubricated lossis qhuav-zaj duab xis coated o-rings
Tsis tas li, koom ua keceev-looj kev sib tsooTxo cov kev ua yuam kev thiab lub sijhawm hauv lub tshav pob.
Tag
Kev sib khi ua kom zoo hauv kev sib txuas ntawm cov khoom sib txuas ntawm tooj dag fittings thiab PE kav dej yog qhov sib tw engineering ntau.
Nws cuam tshuam nrog kev sib haum xeeb cov khoom coj cwj pwm, cov qauv ntsuas duab geometric, kev tswj hwm kev ntxhov siab thiab kev ntxhov siab thiab kho tshuab.
Nrog rau qhov tseeb sealing ntsiab, precision machining, thiab txawj tsim qauv, ntev-ntev kev sib txuas thiab xau dawb ua tiav.
Kev tshawb fawb txuas ntxiv, kuaj, thiab daim teb sau yog qhov tseem ceeb rau kev kho kom zoo nkauj thiab txhim kho kev nyab xeeb thiab kev ua tau zoo thoob plaws dej, roj av.
