Thaum tshav kub kub exchanger yog ib qho ntawm cov khoom siv dav siv hauv kev tsim khoom. Rau ntau qhov laj thawj, cov khoom siv hluav taws xob sib hloov thiab cov kav dej ua rau muaj ntau yam xws li coking, av, nplai, sediment, corrosion khoom, polymers, kab mob, algae, slime thiab lwm yam av. Raws li kev tshawb fawb, ntau dua 90 feem pua ntawm cov khoom siv hluav taws xob sib txawv muaj qhov sib txawv ntawm cov teeb meem fouling. Txhawm rau kom muaj kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob rau lub sijhawm ntev, nws yog ib qho tsim nyog yuav tsum tswj thiab kho cov cuab yeej siv, thiab cov kev pabcuam kuaj tsis tu ncua yuav tsum tau tiv thaiv kev ua haujlwm ntawm cov phaj kub hloov pauv thiab txo qhov tshwm sim ntawm cov xwm txheej.
Cov kev ceev faj:
Ua ntej, kev tshuaj xyuas thiab kev kho mob tsis tu ncua:
1. Tshawb xyuas seb cov khoom siv hluav taws xob puas tawm, thiab sau thiab txheeb xyuas qhov ua rau.
a. Foob gasket tawg - hloov lub gasket tshiab
b. Foob gasket siab dislocation - rov pib dua
c. Loose fastening bolts - rov nruj dua
d. Thaum tshav kub kub exchanger phaj deformation - hloov lub phaj tshiab
2, xyuas seb lub tshuab hluav taws xob hloov hluav taws xob puas muaj peev xwm poob qis, thiab sau thiab txheeb xyuas qhov laj thawj.
a. Txheeb xyuas qhov poob siab - xws li tsis muaj qhov poob siab, qhov xwm txheej feem ntau yog txhaws, ntws, txhaws kev daws teeb meem yog qhib lub tshav kub exchanger los ntxuav thiab rov nruab rau siv. Kev daws rau clogging yog qhib lub tshav kub exchanger thiab ntxuav nws ua ntej rov txhim kho thiab siv nws.
b. Txheeb xyuas qhov kub thiab txias - xws li qhov kub thiab txias tsis ua raws li qhov yuav tsum tau siv, thawj kauj ruam thawj zaug xyuas qhov poob siab raws li saum toj no thiab daws qhov teeb meem. Cov kauj ruam thib ob txhawm rau txheeb xyuas ob sab ntawm qhov ntws thiab qhov ntsuas kub kom ua tau raws li qhov xav tau tsim thiab hloov kho raws li qhov xav tau tiag tiag. Qhov thib peb kauj ruam ntawm kev tshem tawm saum toj no, thov rau qhov chaw tsim khoom daim ntawv ntsuam xyuas.
Thaum tshav kub kub exchanger ua raws li txoj cai ntawm kev txuag hluav taws xob, tsuas yog ua kom sov thiab tsis ua haujlwm, yog li ob sab ntawm lub zog kom phim. Tsis tas li ntawd, qhov nruab nrab yog qhov tshwj xeeb, yooj yim rau clog thiab yooj yim rau scale, yog li koj yuav tsum tsis tu ncua siv cov dej ntws tawm, yaug zaus raws li kev siv cov xwm txheej xws li cov cua kub hloov mus rau qhov tsis tuaj yeem ua raws li kev siv. Thiab ua raws li lub hauv paus ntsiab lus ntawm kev kaw yuav tsum tau yaug kom tsis txhob qhuav scaling thiab lom cov tshuaj tiv thaiv. Kev tu thiab tu cov ntsiab lus tau piav qhia hauv qab no:
Kev tshuaj xyuas qhov tshwm sim thaum disassembled. Txhawm rau txiav txim siab tag nrho corrosion thiab deterioration ntawm txhua feem, yog li tam sim ntawd tom qab dismantling, xyuas cov degree ntawm kev sib kis, dej xeb adhesion, thiab cov qauv kev soj ntsuam thiab kev sim raws li xav tau.
Kev ntxuav ntawm lub tshav kub exchanger. Ua ntej tshaj plaws, ua tib zoo tshem tawm lub gasket ntawm txhua daim ntawv phaj, thaum tshem cov roj hmab gasket peb yuav siv cov kev tiv thaiv tsim nyog los tiv thaiv kev puas tsuaj rau gasket. Tom ntej no, cov phiajcim tau muab tso rau hauv ib lub tshuab ntxuav tshwj xeeb. Txhua kauj ruam ntawm cov txheej txheem ntxuav yog nruj me ntsis tswj kom ntseeg tau tias cov phaj yuav tsum tau ntxuav kom huv si. Nyob ntawm qhov nruab nrab thiab qib ntawm fouling, peb tuaj yeem xaiv cov tshuaj ntxuav, ntxuav lub cev, sib xyaw tshuaj thiab lub cev ntxuav lossis CIP ntawm qhov chaw tsis siv neeg tu.
Kev kuaj DPT yog ua tiav ntawm cov ntawv ntxuav. Siv txoj kev kuaj xim nkag mus, ua ib qho kev kuaj xyuas nruj thiab paub meej tias qhov txhaum, yuav tsum tau kho kom ntseeg tau tias cov phaj zoo li lub Hoobkas tshiab tsis muaj cov kab nrib pleb, cov ntsiab lus corrosion thiab lwm yam tsis xws luag. Tom qab kev ntsuam xyuas xim nkag mus, lub phaj yuav raug ntxuav kom huv si dua nrog kev nkag mus, thiab tom qab ntxuav, lub phaj yuav tshuab ziab sai sai nrog cua compressed.
Sib dhos, rov pib dua, kuaj. Tom qab ntxuav thiab tshuaj xyuas lossis kev saib xyuas thiab kho cov khoom siv hluav taws xob ua kom sov raws li qhov kev txiav txim ntawm kev sib dhos, cov ntsiab lus tseem ceeb, thaum lub sij hawm ntsuas siab los xyuas seb nws puas txawv txav, uas yog, thaum lub rooj sib txoos, rov pib dua.
