Lub shrinkage ntawm roj hmab seals
Roj hmab sealing rings yog ib hom kev sib khi siv nyob rau hauv ntau yam sib txawv ntawm cov tshuab. Lawv lub luag haujlwm tseem ceeb yog txwv tsis pub cov kua los yog roj xau thiab ua kom zoo li lub foob ntawm ob lub ntsiab lus. Txawm li cas los xij, cov roj hmab sealing nplhaib tuaj yeem txo qis thaum siv tiag tiag, uas yuav ua rau cov cuab yeej ua mob ntxiv rau qhov cuam tshuam rau nws lub peev xwm sealing. Cov laj thawj, qhov tshwm sim, thiab cov kev daws teeb meem rau cov roj hmab foob shrinking yuav tau hais meej meej hauv kab lus no.
Yog vim li cas rau roj hmab foob shrinkage
Kev laus ntawm cov khoom siv: Roj hmab sealing rings yuav muaj kev ua haujlwm ntawm cov khoom tsis zoo, kev laus, thiab shrinkage nyob rau lub sij hawm raws li qhov tshwm sim ntawm raug rau sab nraud tej yam kev mob xws li kub, av noo, lub teeb, tshuaj media, thiab lwm yam.
Cov khoom siv roj hmab yuav raug thermal expansion thiab contraction nyob rau hauv teb rau qhov kub thiab txias variations. Shrinkage yuav tshwm sim yog hais tias lub nplhaib sealing raug rau qhov kub hloov pauv thaum siv.
Tshuaj txhuam hniav: Cov khoom siv roj hmab tuaj yeem hnov mob nrog qee cov tshuaj, ua rau cov khoom siv kom qis thiab txhawb nqa kev puas tsuaj.
Mechanical stress: Ib lub foob roj hmab uas raug rau cov neeg kho tshuab tsis tu ncua yuav cuam tshuam thiab ntsws.
Kev khaws cia tsis raug: Cov khoom hloov pauv kev ua haujlwm thiab kev poob qis kuj tuaj yeem tshwm sim los ntawm cov roj hmab sealing nplhaib raug cuam tshuam rau ib puag ncig tsis zoo, xws li kub kub, av noo, thiab lwm yam, thaum khaws cia.
Cov nyhuv ntawm cov roj hmab foob shrinkage
Txo qhov kev ua tau zoo ntawm kev sib khi: Raws li qhov tshwm sim ntawm shrinkage, yuav muaj kev sib cuag tsawg dua ntawm lub nplhaib sib khi thiab qhov chaw sib cuag, uas yuav ua rau cov nyhuv sealing tsawg dua thiab yuav ua rau muaj kua lossis roj.
Cov khoom puas tsuaj: Lub nplhaib sealing lub shrinking yuav ua rau ib qho tsis sib xws nyob rau hauv lub tshuab, uas tej zaum yuav ua rau cov khoom puas.
Cov nqi kho mob siab dua: Nws tuaj yeem siv nyiaj ntau dua thiab siv zog los hloov lossis kho lub foob roj hmab shrunk.
Kev ua haujlwm tsawg zuj zus: Kev ua haujlwm ntau lawm thiab kev nce qib yuav cuam tshuam los ntawm cov khoom siv tsis ua haujlwm los ntawm kev sib khi lub nplhaib shrinking.
Cov txheej txheem los tiv thaiv thiab cuam tshuam nrog roj hmab foob shrinkage
Xaiv cov ntsiab lus tsim nyog: Txhawm rau kom cov roj hmab tiv thaiv kev laus thiab corrosion, xaiv cov khoom tsim nyog raws li qhov kub thiab txias, tshuaj pleev ib ce, thiab lwm yam ntawm qhov chaw ua haujlwm.
Txwv qhov kub hloov pauv: Txhawm rau txo qhov cuam tshuam ntawm thermal expansion thiab txias contraction ntawm lub nplhaib sealing, sim txo qhov kub ntawm qhov sib txawv thaum siv.
Kev kuaj xyuas thiab hloov ntau zaus: xyuas kom cov roj hmab sealing nplhaib feem ntau raug kuaj xyuas. Yog tias pom shrinking, nws yuav tsum tau hloov sai sai kom tswj tau qhov sealing nyhuv.
Txhim khu kev cia khoom: Txhawm rau tiv thaiv cov khoom tsis zoo cuam tshuam rau lawv txoj haujlwm, xyuas kom cov roj hmab sealing nplhaib tau khaws cia rau hauv qhov chaw qhuav, aired, thiab kub-phooj ywg.
Ua hauj lwm prestressed installation: Yuav kom txo tau lub shrinking ntawm cov roj hmab sealing nplhaib tshwm sim los ntawm txhua yam kev nyuaj siab thaum siv, lub prestressing tsim nyog yuav ua tau thaum lub installation.
Xaus
Nws yog ib qho tsim nyog los daws qhov teeb meem ntawm roj hmab sealing nplhaib shrinking. Tej zaum nws yuav muaj kev cuam tshuam rau kev ua haujlwm zoo ntawm cov txheej txheem tsim khoom tiav nrog rau cov khoom siv sealing kev ua tau zoo. Roj hmab foob 'kev pab cuam lub neej yuav ua tau zoo dua, thiab cov khoom siv kev nyab xeeb thiab kev ua haujlwm tau zoo tuaj yeem txhim kho, los ntawm kev nkag siab txog qhov ua rau thiab qhov tshwm sim ntawm shrinkage thiab siv cov kev tiv thaiv thiab kev kho kom zoo.
