Thaum tshav kub kub Exchanger Cleaning txheej txheem

1. cais cov cuab yeej siv thiab tso cov dej hauv cov khoom siv hluav taws xob.
2. Siv cov dej kub siab los ntxuav cov av, algae thiab lwm yam impurities hauv cov kav dej, thiab tom qab ntawd kaw lub kaw lus.
3. Nruab ib lub pob valve (tsis pub tsawg dua 1 nti=2.54 cm) ntawm qhov kev sib cais valve thiab lub exchanger, thiab ob qho tib si dej inlet thiab cov dej rov qab yuav tsum tau ntsia.
4. Txuas lub twj tso kua mis xa khoom thiab cov yeeb nkab sib txuas kom tus neeg saib xyuas ntxuav tau nkag mus rau hauv qab ntawm cov khoom siv hluav taws xob thiab ntws tawm ntawm sab saum toj.
5. Pib nqus cov Fustech tu tus neeg sawv cev rau hauv lub condenser (qhov kev faib ua feem tuaj yeem hloov kho raws li qhov xwm txheej tshwj xeeb).
6. Rov ua lub voj voog tu kom txog thaum lub sij hawm ntxuav tau pom zoo. Raws li lub voj voog zuj zus thiab cov sediment dissolves, cov roj tsim tawm thaum lub sij hawm cov tshuaj tiv thaiv kuj yuav nce ntxiv. Cov huab cua ntau dhau yuav tsum tau tso tawm los ntawm lub qhov cua valve txhua lub sijhawm. Raws li cov huab cua tawm, qhov chaw nyob rau hauv lub tshav kub exchanger yuav nce. Koj tuaj yeem ntxiv dej kom tsim nyog. Tsis txhob tso dej ntau thaum pib, uas yuav ua rau cov dej ntws tawm.
7. Txheeb xyuas qhov ua tau zoo ntawm tus neeg saib xyuas tu tsis tu ncua thaum lub voj voog. Koj tuaj yeem siv daim ntawv ntsuas pH los ntsuas nws. Yog tias cov tshuaj tau khaws cia ntawm tus nqi pH ntawm 2-3, tus neeg ua haujlwm tu tseem siv tau. Yog tias tus nqi pH ntawm tus neeg saib xyuas tau nce mus txog 5-6, nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog ntawm tus neeg saib xyuas Fushitek. Tus nqi pH ntawm qhov kev daws zaum kawg tseem nyob ntawm 2-3 rau 30 feeb yam tsis muaj kev hloov pauv tseem ceeb, uas ua pov thawj tias cov nyhuv ntxuav tau tiav. Nco tseg: Fushitek tus neeg saib xyuas tuaj yeem siv tau thiab rov siv dua, thiab tso tawm yuav ua rau pov tseg.
8. Tom qab lub sijhawm ntxuav, rov ua dua cov tshuaj ntxuav. Thiab yaug lub exchanger rov qab nrog dej huv kom txog thaum nws tau yaug kom huv si, thiab siv daim ntawv kuaj pH los ntsuas pH tus nqi ntawm 6 ~ 7.
9. Tom qab kev ntxuav tiav, koj tuaj yeem pib lub tshuab thiab khiav nws. Koj tseem tuaj yeem ua qhov kev ntsuas siab kom pom tias muaj qhov xau. Yog tias muaj qhov xau, koj tuaj yeem siv Meijiahua polymer cov ntaub ntawv sib xyaw rau kev kho thiab kev tiv thaiv, thiab nws tuaj yeem ua rau lub neej ntev ntawm cov khoom siv.
10. Tom qab cov cuab yeej ruaj khov, sau cov ntaub ntawv nruab nrab tam sim no, kev ua haujlwm siab, kev sib hloov hluav taws xob thiab lwm yam ntaub ntawv.
11. Los ntawm kev sib piv cov kev hloov pauv ntawm cov txiaj ntsig ua ntej thiab tom qab ntxuav, koj tuaj yeem suav cov nqi tsim khoom xws li cov nqi hluav taws xob thiab cov nqi hluav taws xob txuag los ntawm kev lag luam txhua teev thiab kev txhim kho kev ua haujlwm, uas yog tus nqi them nyiaj ntawm lub tuam txhab siv Fushitek. tshuab.
12. Tib txoj kev ua haujlwm kuj tseem tuaj yeem siv los ntxuav cov phaj thiab thav duab kub exchangers.
13. Yog hais tias lub tuam txhab xav tau cov cuab yeej ua kom passivated thiab pre-filmed, cov txheej txheem hauv qab no tuaj yeem ua raws: tso tus neeg sawv cev passivation ua ntej ua yeeb yaj kiab rau hauv cov khoom ntawm qhov pom zoo dilution piv (thaum dai daim ntawv xeem nyob rau hauv lub tank ncig); circulate thiab tsau rau lub sijhawm pom zoo; sim cov nyhuv ua ntej ua yeeb yaj kiab (liab dot method lossis xiav dot method); tso tawm; yaug nrog dej kom txog thaum nruab nrab ( ntsuas pH tus nqi ntawm 6 ~ 7 nrog pH xeem ntawv).
14. Tom qab passivation pre-filming tiav lawm, nws yog qhov zoo tshaj plaws los siv cov khoom cua xws li cov kiv cua kom qhuav lub kaw lus kom paub meej thiab txhim kho cov nyhuv passivation pre-filming.
