Phaj heat exchangers yog cov khoom siv hluav taws xob hloov pauv tau zoo heev siv thoob plaws ntau qhov kev lag luam.
Ob qhov tseem ceeb tshaj plaws ntawm lub phaj kub exchanger yog covtshav kub hloov daim hlauthiab covroj hmab gaskets. Kev ua tau zoo ntawm lub gasket plays lub luag haujlwm tseem ceeb hauv kev cia siab tag nrho ntawm cov khoom siv hluav taws xob. Qhov tseeb, kev txhim kho thiab zoo ntawm cov khoom siv gasket muaj kev cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov phaj kub exchangers.
Thaum lub gasket tsis muab lub foob zoo, cov dej xau tuaj yeem tshwm sim, uas ua rau cov khoom siv poob qis, kev tsim khoom poob, thiab kev kho nqi kim.
Yog li, yam ntxwv dab tsi pab tau aphaj kub exchanger gasketlos muab kev ruaj ntseg sealing kev ua tau zoo?
Cov lus teb yog nyob rau hauv cov nram qab no rau lub luag hauj lwm tseem ceeb.
1. Incompressibility
Synthetic roj hmab tuaj yeem deform nyob rau hauv siab ntau npaum li cov kua hloov cov duab, txawm hais tias nws tsis txaus.
Thaum siv lub zog compressive, lub gasket hloov cov duab thaum tseem ceeb tswj lub ntim tas li.
Thaum lub siab sab nraud raug tshem tawm, lub gasket rov qab mus rau nws qhov qub.
Cov cuab yeej no tso cai rau lub gasket kom ruaj khov sealing kev ua tau zoo thaum rov compression thiab tso tawm.
2. Mechanical Strength
Lub gasket yuav tsum muaj lub zog txhua yam txaus los tiv thaiv lub zog compressive xav tau los tsim kom muaj kev sib khi zoo, nrog rau lub siab ua haujlwm los ntawm cov txheej txheem dej.
Cov khoom tseem ceeb ntawm lub cev muaj xws li lub zog tensile, lub zog elongation, thiab tsis kam mus rau mechanical deformation.
Lub zog txaus kom ntseeg tau tias lub gasket tswj nws txoj haujlwm sealing raws li kev ua haujlwm ib txwm muaj.
3. Plasticity
Los ntawm optimizing cov roj hmab formulation, manufacturers muaj peev xwm ua tau raws li qhov tsim nyog sib npaug ntawm lub zog thiab yooj.
Zoo plasticity tso cai rau lub gasket kom ua raws li cov hlau sealing nto thaum compressed.
Nws kuj tseem ua rau lub gasket profile kom haum rau hauv qhov zawj ntawm lub tshav kub hloov phaj, tsim kom muaj kev ruaj ntseg thiab siv tau zoo.
4. Tsis kam ua kua dej permeation
Qhov peb -seem molecular network qauv ntawm hluavtaws roj hmab muab kev tiv thaiv zoo heev rau kev nkag mus ntawm cov kua thiab tshuaj.
Cov tshuaj tiv thaiv no pab tiv thaiv cov txheej txheem xov xwm los ntawm permeating los ntawm cov khoom siv gasket, kom ntseeg tau ntev -lub sij hawm sealing kev cia siab nyob rau hauv ntau yam kev khiav hauj lwm.
5. Kev tiv thaiv kub
Ib qho kev txwv ntawm cov roj hmab-raws li cov ntaub ntawv polymer yog tias txhua yam khoom ua tau zoo tsuas yog nyob rau hauv qhov kub thiab txias.
Kev kub hnyiab dhau qhov kev txwv kev ua haujlwm tau pom zoo tuaj yeem ua rau kev laus, tawv tawv, lossis poob elasticity.
Vim li no, xaiv cov khoom siv gasket uas tsim nyog raws li daim ntawv thov kev ua haujlwm kub yog qhov tseem ceeb rau kev tswj xyuas kev sib khi.
6. Durability
Piv nrog rau cov khoom siv roj hmab tsoos, ntau cov khoom siv hluavtaws niaj hnub no muab kev pabcuam ntev dua.
Qhov kev txhim kho no feem ntau yog los ntawm kev tsim cov khoom siv qib siab thiab kev ua tau zoo- txhim kho cov khoom ntxiv.
Txawm li cas los xij, txhua yam khoom siv roj hmab-raws li kev ntxhov siab thaum lub sijhawm.
Raws li kev hloov pauv tshuaj tshwm sim hauv cov khoom siv thaum lub sijhawm ua haujlwm, lub gasket maj mam poob ib feem ntawm nws qhov qub sealing quab yuam.
Thaum lub sealing quab yuam poob qis dua qib uas yuav tsum tau ua kom compression, to yuav tsis zam.
Yog li ntawd, xaiv cov khoom siv gasket kom raug thiab hloov cov pa roj carbon monoxide thaum lub sijhawm tu kom tsim nyog yog qhov tseem ceeb rau kev ua kom ntev ntev - cov cuab yeej siv tau ruaj khov.
Xaus
Lub sealing kev ua tau zoo ntawm lub phaj kub exchanger nyob ntawm qhov zoo thiab cov khoom ntawm nws cov roj hmab gaskets.
Lub gasket zoo yuav tsum muab:
Zoo heev incompressibility
Tsim nyog txhua yam muaj zog
Zoo plasticity
Siab tsis kam ua kua permeation
Haum kub kuj
Ntev -lub sij hawm durability
Xaiv cov khoom siv gasket zoo rau kev ua haujlwm -thiab hloov cov pa roj carbon monoxide ua ntej lawv ua tsis tiav- tuaj yeem txhim kho kev ruaj ntseg sealing zoo, txo qis qis qis, thiab txuas ntxiv lub neej kev pab cuam ntawm tag nrho cov phaj kub exchanger.
