1. Cov dej xau: "kua dej seepage" txhaum ntawm cov khoom siv

1.1 Cov tsos mob txhaum cai: Cov kua dej tsis tu ncua

Cov kua dej xau yog hais txog qhov seepage ntawm cov xov xwm ntawm cov phaj kub exchanger. Nws yog tsuas yog muab faib ua sab nraud to thiab sab hauv to. Kev tawm sab nraud txhais tau hais tias qhov nruab nrab dhau los ntawm cov khoom siv plhaub, uas tuaj yeem kuaj pom tau yooj yim. Internal leakage tshwm sim thaum ob hom xov xwm sib xyaw hauv lub exchanger. Nws yog ib qho nyuaj rau pom, thiab feem ntau tsuas pom thaum lub qhov hluav taws xob txawv txav los yog qhov nruab nrab deterioration tshwm.

1.2 Ua rau Kev Ntsuas: Kev laus, kev teeb tsa tsis raug thiab kev puas tsuaj

Muaj ntau yam ua rau cov kua dej tawm. Feem ntau ib qho yog kev laus lossis kev puas tsuaj ntawm sealing gaskets. Ntev -lub sij hawm raug kub, siab thiab tshuaj lom neeg tshaj tawm yuav yooj yim ua rau kev laus thiab tsis ua hauj lwm ntawm gaskets ntawm phaj kub exchangers. Tsis tas li ntawd, kev teeb tsa tsis raug, xws li cov gaskets tsis zoo, tsis txaus los yog lub zog clamping ntau dhau, kuj yog ib qho tseem ceeb ntawm kev xau. Tsis tas li ntawd, deformation lossis perforation ntawm daim hlau los ntawm kev cuam tshuam los yog kev ua haujlwm tsis raug yuav ua rau cov dej ntws tawm thiab.

1.3 Kev daws: Kev tshuaj xyuas thiab hloov cov sealing gaskets thiab daim hlau

Thaum pom tias muaj dej xau, kaw cov cuab yeej ua ntej thiab tshawb xyuas cov sealing gaskets. Hloov cov roj hmab uas muaj hnub nyoog lossis puas tsuaj tam sim ntawd. Thaum txhim kho gaskets tshiab, clamp lawv nyob rau hauv qhov kev txiav txim uas tau teev tseg thiab nrog tus txheej txheem quab yuam kom lav nruj sealing. Rau cov phaj puas, hloov lawv tam sim ntawd kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.

2. Txo cov cua sov hloov ua haujlwm: Cov cua sov hloov thaiv

2.1 Cov tsos mob tsis raug: Kev ntsuas kub tsis zoo thiab kev ua haujlwm tsis zoo poob qis

Txo cov hluav taws xob hloov hluav taws xob yog lwm qhov teeb meem tshwm sim. Nws yog feem ntau tshwm sim raws li qhov hluav taws xob qhov hluav taws xob tsis ua raws li kev tsim qauv lossis kev ua haujlwm txias tsis zoo. Qhov kev ua txhaum no ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem ntau lawm thiab tej zaum yuav txo qis tag nrho cov kev ua tau zoo.

2.2 Ua rau Kev Ntsuas: Scaling, Clogging thiab Uneven Flow Rate

Muaj ob qho laj thawj tseem ceeb rau kev txo qis kev hloov pauv hluav taws xob: sab hauv scaling thiab ntws channel clogging. Scaling cov ntaub ntawv thaum calcium, magnesium ions thiab lwm yam khoom nyob rau hauv cov kua tso rau ntawm lub phaj nto, tsim ib tug insulating txheej uas cuam tshuam cov tshav kub hloov. Flow channel clogging feem ntau yog tshwm sim los ntawm cov khoom sib txuam thiab impurities, uas ua rau cov kua dej tsis sib xws thiab ua rau muaj kev cuam tshuam ntxiv rau kev sib pauv cua sov.

2.3 Cov kev daws teeb meem: Kev ntxuav tu tsis tu ncua thiab kev khiav dej num

Rau scaling, tsis tu ncua tshuaj ntxuav ntawm lub tshav kub exchanger yog qhov zoo tshaj plaws kev daws teeb meem kom tshem tawm cov deposits ntawm lub phaj nto thiab rov ua kom sov hloov lub peev xwm. Nyob rau hauv cov ntaub ntawv ntawm ntws channel clogging, kaw cov cuab yeej thiab disassemble lub tsev kom tshem tawm impurities nyob rau hauv cov channel. Lub caij no, kho cov dej ntws tawm kom ntseeg tau tias txawm tias ntws hauv cov khoom sib hloov thiab txhim kho kev hloov hluav taws xob.

3. Kev poob siab ntau: Cov kua dej tsis haum

3.1 Cov tsos mob tsis zoo: Kev sib txawv ntawm qhov siab thiab cov twj tso kua mis ntau dhau

Kev poob siab ntau dhau txhais tau hais tias qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob nce siab heev thaum cov dej nkag los ntawm cov khoom siv hluav taws xob. Qhov no ua rau kom lub nra ntawm cov twj tso kua mis thiab tej zaum yuav tiv thaiv lub cev los ntawm kev ua raws li cov txheej txheem ib txwm ua. Nws yog feem ntau nrog los ntawm kev txo qis tus nqi thiab degraded tshav kub hloov kev ua tau zoo.

3.2 Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov Kab Ntsig Nkoj thiab cov kav dej tsis zoo

Kev poob siab ntau dhau yog feem ntau tshwm sim los ntawm qhov nqaim ntws thiab tsim cov kav dej tsis zoo. Cov av ntau dhau ntawm cov phiaj los yog kev teeb tsa lub phaj tsis raug yuav ua rau cov dej ntws qis. Tsis tas li ntawd, kev tsim cov kav dej tsis tsim nyog, xws li cov kav dej tsis zoo thiab lub luj tshib ntau dhau, yuav ua rau muaj dej tsis kam thiab ua rau muaj kev sib txawv ntxiv.

3.3 Kev daws: Flow Channel Cleaning thiab Pipeline Optimization

Ua ntej, tshuaj xyuas thiab tshem tawm cov av ntawm cov phaj kom tsis txhob muaj kev cuam tshuam. Yog tias qhov teeb meem tshwm sim, tshuaj xyuas cov yeeb nkab tsim, ua kom zoo dua cov yeeb nkab diameters thiab txiav cov luj tshib uas tsis tsim nyog los txo cov dej tsis kam. Lub caij no, kho cov dej ntws nrawm kom tsim nyog kom tsis txhob poob siab ntxiv los ntawm kev khiav ceev heev.

4. Kev vibration thiab suab nrov: Kev ua haujlwm tsis zoo ntawm cov khoom siv

4.1 Cov tsos mob txhaum cai: Nquag Nquag suab nrov thiab cov cuab yeej tuav

Kev co tsis zoo thiab lub suab nrov thaum lub sijhawm ua haujlwm ntawm cov phaj kub hloov pauv yuav tsis tsuas yog cuam tshuam cov khoom lag luam ib txwm muaj, tab sis tseem ua rau muaj kev cuam tshuam cov saw hlau rau lwm qhov chaw thiab cov txheej txheem tsim khoom. Cov teeb meem zoo li no feem ntau tsis saib xyuas hauv kev ua haujlwm txhua hnub, tab sis lawv feem ntau qhia tau tias muaj peev xwm ua haujlwm lossis kev ua haujlwm tsis raug.

4.2 Ua rau Kev Ntsuam Xyuas: Kev teeb tsa tsis ruaj khov, Kev cuam tshuam ntws thiab kev cuam tshuam

Kev vibration thiab suab nrov tuaj yeem tshwm sim los ntawm kev teeb tsa tsis ruaj ntseg ntawm cov khoom siv hluav taws xob, lossis cov kua dej ntau dhau uas nws cuam tshuam lub zog ntau tshaj qhov muaj peev xwm ntawm cov phaj. Tsis tas li ntawd, resonance yog lwm qhov tshwm sim. Cov cuab yeej zoo li co hnyav thaum nws cov zaus resonant nyob ze rau ntawm lwm yam khoom siv tshuab lossis cov kav dej txuas nrog.

4.3 Kev daws teeb meem: Txhim kho kev txhim kho thiab kho cov haujlwm ua haujlwm

Txhawm rau daws cov teeb meem kev vibration thiab suab nrov, ua ntej tshawb xyuas lub installation thiab xyuas kom meej tias cov khoom siv hluav taws xob tau ruaj khov rau hauv lub hauv paus. Yog tias qhov teeb meem tshwm sim los ntawm kev cuam tshuam, tsim nyog txo cov dej ntws tawm los yog teeb tsa cov khoom siv tsis zoo kom nqus tau qhov cuam tshuam. Rau cov teeb meem resonance, kho cov kev khiav hauj lwm tsis los yog hloov cov kev txhawb nqa kom tsis txhob resonant zaus.

5. Plate Corrosion: Cov khoom siv tsis pom kev

5.1 Cov tsos mob tsis raug: Cov phaj nyias nyias thiab kev ua haujlwm tsis zoo

Phaj corrosion yog ib qho tseem ceeb tshaj plaws ntawm cov phaj kub exchangers. Nws yog tsuas yog manifested raws li pitting thiab qhov nyob rau ntawm lub phaj nto, raws li zoo raws li tag nrho cov thinning thiab txo cov yam ntxwv lub zog ntawm daim hlau. Yog tias tsis kho, qhov ua txhaum no tuaj yeem ua rau cov khoom puas tsuaj loj thiab ua rau muaj kev sib tsoo ntau lawm.

5.2 Kev soj ntsuam ua rau: Corrosive nruab nrab thiab xaiv cov khoom tsis raug

Corrosion ntawm daim hlau feem ntau yog tshwm sim los ntawm cov tshuaj yaig los ntawm cov khoom corrosive hauv cov kua nruab nrab. Corrosion zoo li tshwm sim yog tias cov khoom siv phaj xaiv tsis yog corrosion-resistant lossis cov khoom ntawm cov kua nruab nrab yog misjudged. Tsis tas li ntawd, kev ua haujlwm tsis zoo xws li qhov kub thiab txias tshaj tawm tuaj yeem ua kom cov txheej txheem corrosion.

5.3 Kev daws teeb meem: Kev xaiv cov khoom zoo tshaj plaws thiab kev tshuaj xyuas tsis tu ncua

Txhawm rau tiv thaiv kev xeb ntawm phaj, xaiv qhov tsim nyog corrosion- cov ntaub ntawv tiv taus xws li stainless hlau thiab titanium alloys raws li cov yam ntxwv ntawm cov kua nruab nrab. Thaum pom cov cim ntawm corrosion, kaw cov cuab yeej tam sim ntawd thiab hloov cov ntawv corroded. Lub caij no, kho cov txheej txheem tsis ua haujlwm kom txo tau qhov cuam tshuam ntawm corrosive media. Nws tseem yog ib qho tsim nyog yuav tsum tau ua raws li kev tshuaj xyuas tsis tu ncua txhawm rau txheeb xyuas thiab daws cov teeb meem corrosion thaum ntxov, txhawm rau txhawm rau txuas lub neej kev pab cuam ntawm lub tshav kub exchanger.
