Caij nplooj ntoos hlav Foob / Caij nplooj ntoos hlav Energized Foob / Variseal yog ib qho kev sib khi ua haujlwm siab nrog U-puab Teflon sab hauv tshwj xeeb caij nplooj ntoos hlav.Los ntawm kev siv lub caij nplooj ntoos hlav tsim nyog thiab lub zog ua kua dej, lub sealing di ncauj (lub ntsej muag) raug thawb tawm thiab maj mam nias tawm tsam cov hlau nto raug kaw kom tsim tau cov nyhuv sealing zoo.Cov nyhuv actuation ntawm lub caij nplooj ntoos hlav tuaj yeem kov yeej me ntsis eccentricity ntawm cov hlau mating nto thiab hnav ntawm daim di ncauj sealing, thaum tswj qhov kev cia siab sealing kev ua tau zoo.
Teflon (PTFE) yog cov khoom sib khi nrog cov tshuaj tiv thaiv zoo tshaj plaws thiab cov cua kub zoo piv rau perfluorocarbon roj hmab.Nws tuaj yeem siv rau feem ntau ntawm cov kua dej tshuaj, cov kuab tshuaj, nrog rau cov roj hydraulic thiab lubricating roj.Nws tsis tshua muaj peev xwm o tuaj yeem tso cai rau kev sib khi mus ntev.Ntau yam tshwj xeeb springs yog siv los kov yeej cov teeb meem elastic ntawm PTFE lossis lwm cov khoom siv roj hmab ua haujlwm siab, Tsim cov ntsaws ruaj ruaj uas tuaj yeem hloov tau qhov feem ntau ntawm cov ntawv thov hauv static lossis dynamic (reciprocating lossis rotary motion), nrog rau qhov kub thiab txias ntawm cov tub yees mus txog 300 ℃. , thiab lub siab ntau ntawm lub tshuab nqus tsev mus rau qhov siab siab ntawm 700kg, nrog kev txav ceev txog li 20m / s.Springs tuaj yeem siv rau hauv ntau qhov kub-kub corrosive kua los ntawm kev xaiv stainless hlau, Elgiloy Hastelloy, thiab lwm yam raws li qhov sib txawv siv ib puag ncig.
Lub caij nplooj ntoos hlav foobtuaj yeem ua raws li tus qauv AS568AO-ringzawj (xws li radial ncej foob,piston foob, axial lub ntsej muag foob, thiab lwm yam), tag nrho hloov lub universal O-ring.Vim tsis muaj qhov o, nws tuaj yeem tswj tau qhov kev sib khi zoo rau lub sijhawm ntev.Piv txwv li, rau cov neeg kho tshuab ntsaws ruaj ruaj siv nyob rau hauv high-temperature corrosive ib puag ncig nyob rau hauv petrochemical txheej txheem, feem ntau ua rau kom tsis yog tsuas yog unevenly hnav ntawm zawv zawg nplhaib, tab sis kuj deterioration thiab kev puas tsuaj ntawm O-ring.Tom qab hloov mus rau HiPerSeal, cov teeb meem xws li roj hmab softening, o, nto coarsening, thiab hnav tuaj yeem txhim kho tag nrho, yog li txhim kho kev pab cuam lub neej ntawm cov tshuab ntsaws ruaj ruaj.
Lub caij nplooj ntoos hlav foob yog tsim rau ob qho tib si dynamic thiab zoo li qub daim ntaub ntawv.Ntxiv nrog rau cov ntawv thov sealing nyob rau hauv high-temperature corrosive ib puag ncig uas tau hais los saum no, nws yog qhov tsim nyog rau sealing cov khoom ntawm huab cua thiab roj lub tog raj kheej vim nws tsis tshua muaj sealing di ncauj kev sib txhuam coefficient, ruaj khov sealing kev sib cuag siab, siab siab ua haujlwm, tso cai loj radial khiav. tawm, thiab groove loj yuam kev.Nws hloov U-shaped lossis V-shaped compression kom ua tiav kev sib khi zoo thiab kev pabcuam lub neej.
Installation ntawm Spring Seal
Lub rotary caij nplooj ntoos hlav foob yuav tsum tsuas yog ntsia rau hauv qhib grooves.
Txhawm rau koom tes nrog kev sib koom ua ke thiab kev teeb tsa tsis muaj kev ntxhov siab, ua raws cov kauj ruam hauv qab no:
1. Muab lub foob rau hauv qhov qhib qhib;
2. Txhim kho lub hau kom tsis txhob nruj ua ntej;
3. Txhim kho cov ncej;
4. Kho lub hau npog ntawm lub cev.
Cov yam ntxwv ntawm lub caij nplooj ntoos hlav foob raws li hauv qab no:
1. Lub sealing kev ua tau zoo tsis cuam tshuam los ntawm lubrication tsis txaus thaum pib;
2. Txo qhov hnav thiab kev sib txhuam zoo;
3. Los ntawm kev sib xyaw ua ke ntawm cov khoom sib txuas sib txawv thiab cov khoom siv sib txawv, cov sealing sib txawv tuaj yeem tshwm sim kom tau raws li ntau yam kev thov.Tshwj xeeb CNC machining mechanisms yog siv, tsis muaj pwm nqi - tshwj xeeb tshaj yog haum rau ib tug me me ntawm ntau hom sealing Cheebtsam;
4. Cov tshuaj tiv thaiv corrosion thiab kub tsis kam yog qhov zoo tshaj plaws rau kev siv cov roj hmab sealing, nrog qhov ntev ruaj khov thiab tsis muaj kev puas tsuaj rau kev sib khi ua haujlwm los ntawm qhov ntim o los yog shrinkage;
5. Cov qauv zoo heev, tuaj yeem ntsia tau rau hauv cov qauv O-ring grooves;
6. Txhim kho qhov muaj peev xwm sib khi thiab lub neej ua haujlwm zoo;
7. Qhov zawj ntawm cov khoom sib khi tuaj yeem sau nrog cov khoom siv los tiv thaiv kev ua qias tuaj (xws li silicone) - tab sis nws tsis haum rau qhov chaw tawg;
8. Raws li cov khoom sib khi yog Teflon, nws huv heev thiab tsis ua rau cov txheej txheem ua paug.Kev sib txhuam coefficient tsis tshua muaj siab, thiab txawm tias nyob rau hauv daim ntawv thov ceev heev, nws zoo heev yam tsis muaj "hysteresis effect";
9. Tsawg pib kev sib txhuam tsis zoo, muaj peev xwm tswj tau qis pib lub zog ua haujlwm txawm tias lub tshuab raug kaw rau lub sijhawm ntev lossis ua haujlwm tsis tu ncua
Daim ntawv thov ntawm Spring Energized Seal
Lub caij nplooj ntoos hlav foob yog ib qho kev sib khi tshwj xeeb tsim rau kev siv nrog kub corrosion, nyuaj lubrication, thiab tsis tshua muaj kev sib txhuam.Kev sib xyaw ua ke ntawm cov khoom sib txawv Teflon sib xyaw, cov khoom siv hluav taws xob siab tshaj plaws, thiab cov hlau tsis muaj zog corrosion tuaj yeem ua tau raws li qhov xav tau ntau haiv neeg ntawm kev lag luam.Cov ntawv thov ib txwm muaj xws li:
1. Axial cov ntsaws ruaj ruaj rau qhov sib txuas ntawm kev thauj khoom thiab tshem tawm caj npab;
2. Cov ntsaws ruaj ruaj rau painting li qub los yog lwm yam painting systems;
