A phaj kub exchangeryog cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob sib txuas siv dav siv hauv cua sov, cua txias, evaporation, condensation, thiab lwm yam txheej txheem.Nws muaj ib tug series ntawm hlau daim hlau kaw nrog roj hmab gaskets, ua ib tug series ntawm ntws raws.Cov kua dej ntws nruab nrab ntawm cov phaj uas nyob ib sab, sib pauv cua sov los ntawm cov phaj conductive.

Txawm li cas los xij, hauv kev siv cov tswv yim, cov roj hmab gaskets hauv cov phaj kub hloov pauv tuaj yeem ua rau puas, ua rau txo qis kev sib pauv hluav taws xob thiab muaj feem cuam tshuam rau kev ua haujlwm ntawm tag nrho cov kab ke.Yog li, dab tsi yog qhov ua rau cov roj hmab gasket puas nyob rau hauv phaj kub exchangers?

Tshuaj Corrosion

Ua ntej, tshuaj corrosion yog ib qho ua rau cov roj hmab gasket puas.Cov tshuaj lom neeg ntawm cov kua dej hauv cov khoom siv hluav taws xob, xws li cov kua qaub muaj zog, cov hauv paus muaj zog, lossis cov kuab tshuaj organic, tuaj yeem ua rau cov khoom siv roj hmab gasket, ua rau nws degrade, soften, los yog harden, ua rau kev puas tsuaj.Tsis tas li ntawd, qee cov tshuaj tuaj yeem ua rau cov khoom siv roj hmab ua kom lub cev qhuav dej, ua rau cov roj hmab poob elasticity thiab ntxiv rau qhov kev puas tsuaj ntxiv.

Kub kub

Qhov thib ob, qhov kub thiab txias kuj yog ib qho tseem ceeb ntawm cov roj hmab gasket puas tsuaj.Txhua yam ntawm cov khoom siv roj hmab muaj nws tus kheej qhov kub thiab txias.Yog hais tias qhov kub thiab txias nyob rau hauv lub tshav kub exchanger tshaj cov roj hmab gasket qhov kam rau ua, lub gasket yuav soften, muaj hnub nyoog, poob elasticity, thiab nws thiaj li ua puas.Hauv particular, nyob rau hauv ib puag ncig kub, kev ua haujlwm ntawm cov khoom siv roj hmab txo qis, ua rau muaj kev pheej hmoo ntawm kev puas tsuaj.

Siab dhau

Kev siab dhau yog lwm qhov ua rau cov roj hmab gasket puas tsuaj.Thaum lub sij hawm ua hauj lwm ntawm lub tshav kub exchanger, system siab fluctuations los yog ua hauj lwm tsis ua hauj lwm yuav ua rau cov roj hmab gasket dais siab tshaj nws kam rau ua ntau yam, uas ua rau kev puas tsuaj.Tshwj xeeb tshaj yog thaum lub kaw lus nquag pib thiab nres lossis kev hloov pauv loj heev, lub gasket yog qhov ua rau puas tsuaj.

Dej cuam tshuam

Kev cuam tshuam cov kua kuj tuaj yeem ua rau cov roj hmab gasket puas.Thaum cov kua dej ntws los ntawm kev kub ceev, qhov cuam tshuam lub zog ntawm lub gasket yog qhov tseem ceeb, thiab kev cuam tshuam rau lub zog ntev ntev tuaj yeem ua rau gasket puas.Qhov no tshwj xeeb tshaj yog nyob rau hauv lub qhov hluav taws xob los yog qhov hluav taws xob ntawm lub tshav kub exchanger, qhov twg cov kua speeds siab dua.

Kev teeb tsa tsis raug

Kev teeb tsa tsis raug yog tib neeg ua rau cov roj hmab gasket puas tsuaj.Thaum lub sij hawm installation, yog hais tias lub gasket tsis raug muab tso los yog heev compressed, nws yuav puas.Tsis tas li ntawd, cov cuab yeej siv tsis raug lossis cov txheej txheem siv thaum lub sijhawm disassembly thiab kev teeb tsa los ntawm cov neeg ua haujlwm tuaj yeem ua rau lub gasket puas.

Natural Aging

Thaum lub sij hawm, cov khoom siv roj hmab ib txwm muaj hnub nyoog vim yog oxidation, poob lawv cov khoom sib khi.Cov txheej txheem kev laus no tau nrawm rau hauv qhov kub thiab txias, cov av noo, lossis muaj zog UV ib puag ncig, ua rau lub neej ntev ntawm lub gasket.

Kev ua haujlwm yuam kev

Kev ua haujlwm yuam kev tuaj yeem ua rau cov roj hmab gasket puas tsuaj.Piv txwv li, ceev ceev qhib los yog kaw li qub thaum lub sij hawm tshav kub exchanger ua hauj lwm yuav ua rau mob hnyav hloov, ua rau lub gasket puas.Ntxiv mus, tsis ua raws li cov txheej txheem kev khiav hauj lwm kuj tuaj yeem ua rau gasket puas.

Kev tu tsis zoo

Kev saib xyuas tsis zoo yog lwm qhov ua rau cov roj hmab gasket puas.Yog tias tsis muaj kev tu thiab tshuaj xyuas kom zoo thaum lub sijhawm ua haujlwm ntev, cov av thiab cov khoom tuaj yeem ua rau hnav lossis khawb ntawm lub gasket.Qhov no yog qhov teeb meem tshwj xeeb hauv cov dej tsis zoo lossis cov kua dej uas muaj ntau yam khoom, ua rau lub gasket muaj kev puas tsuaj.

Txhawm rau kom muaj kev ua haujlwm zoo ntawm lub phaj kub hloov pauv thiab txuas ntxiv lub neej ntawm cov roj hmab gasket, ntau yam yuav tsum tau ua.Ua ntej, thaum lub sij hawm tsim thiab xaiv, nws yog ib qho tseem ceeb kom nkag siab txog cov kev ua hauj lwm thiab cov kua dej ntawm lub tshav kub exchanger tag nrho thiab xaiv cov ntaub ntawv uas tsim nyog gasket thiab tsim nyog txoj kev khiav hauj lwm.Qhov thib ob, thaum lub sijhawm teeb tsa thiab kev ua haujlwm, kev ua raws li cov txheej txheem kev ua haujlwm yog tsim nyog kom tsis txhob muaj kev puas tsuaj los ntawm kev ua haujlwm yuam kev.Tsis tas li ntawd, kev tshuaj xyuas tsis tu ncua, tu, thiab kev saib xyuas cov khoom siv hluav taws xob, nrog rau kev hloov cov gaskets puas, yog qhov tseem ceeb.

Hauv kev xaus, qhov ua rau cov roj hmab gasket puas nyob rau hauvphaj kub exchangersmuaj ntau yam, nrog rau cov tshuaj tiv thaiv corrosion, kub kub, siab dhau, dej cuam tshuam, kev teeb tsa tsis raug, cov khoom laus, kev ua haujlwm tsis zoo, thiab kev saib xyuas tsis zoo.Txhawm rau kom muaj kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob thiab txuas ntxiv lub neej ntawm gasket, ntau yam kev tiv thaiv thiab kev kho yuav tsum tau ua.Los ntawm tsim nyog tsim, xaiv, kev teeb tsa, kev ua haujlwm, thiab kev saib xyuas, qhov kev pheej hmoo ntawm gasket puas tuaj yeem txo qis, txhim kho cov khoom siv hluav taws xob ua haujlwm zoo thiab ruaj khov.
