Plate heat exchangers kuj hu ua phaj kub exchangers. Ntxiv nrog rau kev saib xyuas nyob rau hauv cov xwm txheej tshwj xeeb, kev saib xyuas tsis tu ncua yuav tsum tau ua. Vim hais tias lub phaj kub exchanger yog ib qho yooj yim rau disassemble thiab sib sau ua ke, thiab kev saib xyuas yog yooj yim, tshwj xeeb cov cuab yeej thiab khoom siv feem ntau tsis xav tau. Cov txheej txheem sib txawv tuaj yeem siv raws li qhov sib txawv. Yog tias cov cuab yeej tsis xau, tab sis qhov hloov hluav taws xob hloov hluav taws xob K tau poob, koj tuaj yeem siv lub kaw lus kaw kom tso cov kua descaling rau hauv cov khoom siv thiab xa mus rau ob peb teev yam tsis tas yuav disassembled lub tshav kub exchanger. That' yog. Tsis muaj qhov xwm txheej zoo li no rau ntawm qhov chaw, thiab thaum cov cuab yeej raug tshem tawm lossis cov nplai pom tias tsis hnyav, koj tuaj yeem ntxuav nws ncaj qha nrog dej yam tsis tau tshem lub phaj, thaum txhuam nrog txhuam mos. Cia's ua tib zoo saib ntawm kev saib xyuas cov kauj ruam!
1. Chaw nres tsheb
Thaum kaw rau kev txij nkawm, ua ntej maj mam kaw cov kua li qub ntawm ob sab ntawm lub tshuab hluav taws xob, kom lub siab ntawm ob sab tee maj mam nyob rau tib lub sijhawm, thiab tom qab ntawd loosen cov txiv ntseej nruj tom qab tshem tawm cov kua seem. Thaum disassembling lub khi pas nrig, qhov kub thiab txias yuav tsum tau qis rau hauv chav tsev kub thiab cov kua seem yuav tsum tau muab pov tseg kom ntau li ntau tau ua ntej yuav mus.
2. phaj ntxuav
Qhov chaw huv thiab tsis muaj oxide ntawm lub phaj yog qhov tsim nyog los xyuas kom nruj. Thaum lub thermal efficiency ntawm lub phaj kub exchanger yog txo, thiab lub siab poob yog ho hloov, lub scaling yog loj, thiab cov phaj yuav tsum tau disassembled thiab ntxuav. Siv cov npuas npuas tank thiab tshuaj ntxuav cov txheej txheem yog ib txoj hauv kev zoo kom tau txais cov khoom zoo. Thaum ntxuav, ua ntej muab lub phaj tso rau hauv lub tank lye nrog qhov kub ntawm 57-60 ° C (yog tias qhov kub ntawm 70-80 ° C) rau 48h, thiab siv qhov kub ntawm cov lye los ua cov sealant rau ntawm lub phaj. thiab fouling soften. Tom qab ntawd, soak lub phaj nyob rau hauv cov kua qaub da dej rau 2 xuab moos kom tag nrho cov nplai nrog cov kua qaub. Tom qab lub phaj yog tsau, ntxuav nws nrog ib tug mos txhuam ntawm lub platform, thiab nws yog txwv tsis pub siv hlau txhuam.
Thaum ntxuav lub sealing zawj, nqa lub tshuab ntxhua khaub ncaws nrog lub hau ntswj, maj mam tshem nws (los yog maj mam ci nws nrog hluav taws rau sab nraub qaum, tab sis tsis txhob muaj cov hlau tsis muaj xim), thiab tom qab ntawd rub nws tawm. Siv acetone methyl kua los yog lwm yam ketone cov kuab tshuaj los ntxuav lub tank kaw.
Yaug cov ntawv ntxuav nrog dej huv ua ntej, thiab tom qab ntawd qhuav nrog daim ntaub huv. Tsis muaj cov khoom txawv teb chaws los yog fibers raug tso cai rau ntawm lub phaj. Cov ntsiab lus chloride ion ntawm cov dej ntxuav yog tsawg dua lossis sib npaug li 25pp.
3. Tshawb xyuas thiab paub meej tias cov haujlwm ua haujlwm. Tom qab ntxuav, xyuas cov phaj kom zoo. Muaj peb txoj hauv kev tshuaj xyuas:
1. Xim txoj kev: kos nrog tus neeg pleev xim;
2. Txoj kev sib kis ntawm lub teeb: lub teeb ci tau muab tso rau ntawm ib sab ntawm lub phaj, thiab cov neeg tuaj xyuas ntawm sab nraud;
3. Ib txoj kev ntsuas siab ntawm ib sab: Kev ntsuas dej ntawm ib sab mus rau 0.35MPa (gauge siab), yog tias muaj dej ntawm qhov qis tshaj plaws ntawm sab nraud, tshawb xyuas qhov ntub dej ntawm lub phaj sai sai. Peb xaiv txoj kev sib kis ntawm lub teeb rau kev tshuaj xyuas, uas muaj qhov zoo ntawm kev yooj yim thiab tus nqi qis, thiab tsim nyog rau kev tshuaj xyuas cov ntawv tshiab thiab qub. Tab sis kev nkag siab ntawm lub luag haujlwm ntawm cov neeg ua haujlwm saib xyuas yog siab.
Raws li qhov xwm txheej tshuaj xyuas ntawm lub rooj tsavxwm, txiav txim siab ua haujlwm, muaj peb yam tseem ceeb:
1. Hloov tag nrho cov phaj thiab gaskets;
2. Tsuas yog hloov lub gasket;
3. Hloov cov gaskets thiab cov phaj puas lossis deformed heev.
Plaub, lub gasket muab tshuaj txhuam
Siv cov nplaum nplaum los yog cov nplaum muaj zog los siv cov txheej txheem sib npaug rau hauv qab ntawm qhov sib khi, thiab tom qab ntawd muab lub gasket rau hauv qhov sib khi, lo nws sib npaug, nias, qhuav ib txwm, lossis cua sov rau 100 ℃ - 120 ℃ rau ob teev cia qhuav. tom qab ntawd. Tshawb xyuas ib qho los ntawm ib qho kom pom tias qhov haum yog qhov sib npaug, thiab tshem tawm cov nplaum ntau dhau.
Thib tsib, kev sib dhos
Cov yam ntxwv ntawm cov txheej txheem ntawm cov phaj kub exchanger kev sib xyaw ua ke yog: yog tias cov kua dej nkag los ntawm lub qhov ntawm lub kaum sab laug ntawm lub phaj, nws ib txwm tawm ntawm lub qhov ntawm lub kaum sab laug ntawm lub phaj, thiab rov ua dua. Thaum sib sau ua ke, nws yuav tsum paub qhov txawv ntawm A board thiab B board kom raug, uas yog: coj mus rau sab ntawm daim ntawv nplaum nplaum ua rau pem hauv ntej, paub qhov txawv raws li kev taw qhia ntawm txoj kab sib txawv, thiab teeb lub phaj nrog txoj kab sib txawv hauv ib qho. qee qhov kev taw qhia raws li A phaj, ces cov lus qhia Lub phaj nrog tus khiav hauv lwm qhov kev taw qhia yog B phaj, tab sis tsis muaj qhov cim ntawm lub phaj.
Thib rau, kev sim hydraulic
Plaub lub qhov muag tsis pom daim hlau yog ua raws li qhov loj ntawm cov yeeb nkab txuas flange, thiab lawv tau welded ntawm qhov nkag thiab tawm, thiab cov kav dej yog welded rau ntawm daim hlau los txuas cov compressor thiab cov cua kub exchanger. Nruab ib lub ntsuas ntsuas siab uas tau dhau qhov kev pov thawj thiab nyob rau hauv lub sijhawm siv tau ntawm qhov nkag thiab qhov hluav taws xob. Qhov ntau ntawm lub ntsuas ntsuas yuav tsum yog ob zaug ntawm qhov ntsuas siab. Kev ntsuas siab yog 1.5 npaug ntawm kev ua haujlwm siab.
1. Ua kev tshuaj xyuas thiab kho kom nruj raws li cov kev xav tau saum toj no, qhov ua tau zoo ua tau raws li cov qauv tsim, thiab tsis muaj qhov xau thaum lub sij hawm 72-teev load test. Kev ntsuas qhov ntsuas kub ntawm cov kua hluav taws xob hloov pauv: lub alumina niam cawv inlet yog 45.2 ° C, qhov hluav taws xob yog 84.6 ° C; alumina phev inlet yog 97.0 ° C, thiab qhov hluav taws xob yog 78 ° C, uas ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm ib txwm muaj.
2. Kev txuag nqi. Txij li cov khoom siv phaj yog ultra-nyias Crl7Nil3Mo2Ti stainless hlau, thiab lub gasket kuj yog tshwj xeeb, nws yog kim heev los hloov tag nrho cov phaj tshiab. Tom qab ntxuav, tshuaj xyuas thiab rov siv dua, ib lub phaj kub hloov pauv tuaj yeem txuag tau 250,000 txog 450,000 yuan hauv tus nqi.
