Sealing Failure Mechanism & Anti-Kev Kho Kev Laus Rau Kev tawg-Cov pov thawj cua sov Tubes
Sealing system tsis ua hauj lwm yog qhov feem ntau pom tsis pom qhov txhaum ntawm kev tawg- cov ntaub ntawv pov thawj cua sov hauv lub sijhawm ua haujlwm ntev -. Tsis zoo li pom tseeb cua sov tsis ua hauj lwm thiab Circuit Court txhaum, sealing kev laus thiab kev puas tsuaj tsis muaj cov tsos mob tshwm sim tam sim ntawd, tab sis ncaj qha ua rau cov tub ntxhais tawg tawg - pov thawj muaj nuj nqi cais tawm. Raws li kev saib xyuas cov txheeb cais, ntau dua 70% ntawm kev tawg- pov thawj cua sov tube kev nyab xeeb kev ua haujlwm attenuation pib los ntawm kev sib khi tivthaiv kev laus, uas yog qhov txuas tseem ceeb ntawm kev saib xyuas txhua hnub thiab kev tshem tawm tsis zoo.
Explosion-cov ntaub ntawv pov thawj sealing tshuab txais ntau- txheej txheej cais cais. Lub innermost siab -kub resistant insulating muab tub lim paub txog rwb thaiv tsev thiab tshav kub conduction sealing ntawm hluav taws xob cua sov hlau thiab hlau raj lub cev. Qhov nruab nrab compression sealing gasket ua tiav qhov sib txawv ntawm lub raj lub cev thiab tawg - pov thawj plhaub. Kev tawg sab nraud-cov pov thawj cable sealing gland cais tawm cov hluav taws xob sab nraud los ntawm qhov chaw hauv Circuit Court. Cov txheej txheem peb - txheej txheej tsim kom muaj kev sib cais kev nyab xeeb kaw kom tsis txhob muaj cov pa hluav taws xob sab nraud thiab cov plua plav nkag mus rau hauv thaj chaw hluav taws xob sab hauv.
Sealing aging ua raws li cov cai tswj kev ua haujlwm ruaj khov raws li kev ua haujlwm hauv kev lag luam. Ntev -lub sij hawm siab- kub thermal cycling ua rau elastic gaskets harden, deform thiab poob compression kev ua tau zoo. Cov xov xwm ntub dej thiab corrosive erodes sealing cov ntaub ntawv, ua rau micro- tawg thiab qhov sib txawv. Cov cuab yeej nquag vibration thiab kub alternation accelerate sealing qauv qaug zog kev puas tsuaj, tsim me me nkag kis. Kev sib khi me ntsis tso cai rau cov kab hluav taws xob tawg nkag mus rau hauv lub plhaub, thiab cov hluav taws xob sab hauv hluav taws xob thiab kub kub yuav ua rau muaj kev phom sij txaus ntshai nyob rau hauv huab cua.
Cov ntaub ntawv sib khi sib txawv muaj qhov sib txawv ntawm lub neej kev pabcuam thiab kev hloov pauv. Cov khoom siv roj hmab sib khi zoo ib yam muaj tus nqi qis tab sis tsis zoo siab -kub tsis kam, haum rau qis - qhov kub thiab txias ua haujlwm zoo li qub. Silicone thiab fluorine roj hmab sealing cov ntaub ntawv txhim kho siab - kub thiab corrosion kuj, hloov mus rau feem ntau cov pa phem ib puag ncig. Hlau composite sealing gaskets muaj ultra- kub tsis kam thiab kev laus tsis kam, siv rau siab - kub ua haujlwm tawg tsis tu ncua - cov khoom pov thawj.
Cov kev pabcuam kev ua haujlwm thiab cov ntaub ntawv pheej hmoo tsis ua haujlwm ntawm cov qauv sib khi sib txawv yog qhia hauv cov lus hauv qab no:

Kev tshawb xyuas qhov ua txhaum ntawm thaj chaw qhia tau hais tias kev hloov pauv cov khoom sib txuas tsis tu ncua thiab qhov sib txawv ntawm qhov sib txawv tuaj yeem tshem tawm 90% ntawm kev tawg- pov thawj zais qhov phom sij los ntawm kev sib khi tsis ua haujlwm. Kev tsis saib xyuas kev sib khi ua rau ua rau cov khoom tawg tawg zuj zus zuj zus - cov ntaub ntawv pov thawj muaj txiaj ntsig, ua tsis tau raws li cov qauv kev nyab xeeb kev nyab xeeb hauv cheeb tsam.
Cov txheej txheem kev tswj xyuas kev sib khi ua tau zoo tuaj yeem tsim cov kev tshuaj xyuas tshwj xeeb thiab cov phiaj xwm hloov khoom siv raws li cov khoom siv ua haujlwm kub thiab ib puag ncig tus yam ntxwv, tswj kom tawg tag- pov thawj sealing kev ua tau zoo ntawm cov raj cua sov thoob plaws lub sijhawm ua haujlwm.
