Copper yeeb nkab nyob rau hauv weld tag solidified ua ntej, tsis tuaj yeem txav lub vuam los yog ua rau nws raug kev co. Rau kev siv cov dej-txias weldments, dej yuav tsum tau tiv thaiv kom tsis txhob nkag mus rau sab hauv ntawm cov yeeb nkab tooj liab, thiab thaum muab cov welds, nws tseem yuav tsum tsis txhob muaj cov dej seem ntawm cov yeeb nkab tooj liab los ntawm ntws mus rau hauv cov yeeb nkab. Niaj hnub no, Gnee yuav qhia rau koj txog kev tiv thaiv kev ntsuas thiab kev tsim kho zoo ntawm cov kav dej tooj liab, thiab kuv vam tias nws tuaj yeem pab koj.
Copper pipe flushing and disinfection, anti-corrosion ntsuas:
(1) piping system installation thiab txais yuav tiav, vim hais tias cov yeeb nkab nyob rau hauv txoj kev tsim kho tej zaum yuav muaj tooj liab hais, solder paste thiab lwm yam impurities nyob rau hauv cov yeeb nkab, yuav tsum tau ua tib zoo yaug kom tshem tawm cov residues.
(2) Ntxiv 0.05% tshuaj tua kab mob poov tshuaj permanganate rau hauv dej yaug. Tsis txhob so nrog cov tshuaj chlorine rau kev tua kab mob.
3) Txuas qhov kawg ntawm lub kaw lus nrog lub hose hauv series, thiab txuas qhov kawg ntawm lub hose mus rau lub tank cia dej.
4) Teeb lub tank tso dej thiab lub twj tso kua dej ntawm qhov nkag ntawm qhov system dua. Cov dej twj tso kua mis inlet thiab qhov hluav taws xob txuas nrog lub tank dej system inlet.
5) dej cia dej ntws tawm, yaug mus rau qhov hluav taws xob dej zoo thiab nkag mus rau tib qhov kev tshuaj ntsuam xyuas.
6) Tom qab kev teeb tsa ntawm cov yeeb nkab tooj liab, yuav tsum tau pleev xim rau ntawm phab ntsa sab nrauv ntawm cov xim pleev xim, tiv thaiv xeb rau cov txheej txheem tiv thaiv corrosion, pleev xim yuav tsum zoo ib yam.
Qhov kev xav tau zoo ntawm qhov project thiab kev lees txais:
1. Cov kav dej tooj liab yuav tsum ua raws li qhov xwm txheej thiab cov yam ntxwv ntawm qhov project rau kev tshuaj xyuas tus kheej, kev lees paub nruab nrab thiab kev lees paub tiav. Concealed installation, piping ua ntej concealment, tag nrho cov system yuav tsum tau muab ntsia rau qhov kawg ntawm qhov kev ntsuam xyuas dej nruj.
2. Kev ntsuas siab yog 1.5 npaug ntawm qhov tsim ua haujlwm siab ntawm cov kav dej, tab sis tsis tsawg dua 0.9Mpa.
3. Ua ntej qhov kev ntsuam xyuas hydrostatic yuav tsum ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo rau kev tiv thaiv cov yeeb nkab, tab sis qhov sib koom ua ke yuav tsum raug nthuav tawm.
4. Hydraulic xeem thiab ua cov ntaub ntawv tsim nyog tsuas yog tom qab kev tsim kho raws li kev tsim kho vaj tse.
Hydraulic Test cov kauj ruam:
(1) qhov ntsuas siab ntawm cov kav dej ntawm txhua qhov chaw faib dej thaiv, kev txhaj tshuaj maj mam, cov txheej txheem dej txhaj tshuaj tib lub sijhawm yuav raug cais tawm ntawm cov yeeb nkab roj.
(2) piping system yog tag nrho ntawm cov dej, dej tsis zoo xyuas.
(3) pressurization ntawm lub system, pressurization yuav tsum tau siv tes twj tso kua mis kom maj mam nce siab, siab yuav tsum tsis txhob tsawg tshaj li 10 feeb.
(4) nce mus rau qhov ntsuas qhov ntsuas siab, nres qhov siab, stabilizing siab rau 1 teev, soj ntsuam cov pob qij txha rau cov dej ntws.
(5) 1 teev tom qab ua kom lub siab ruaj khov, thiab tom qab ntawd ua kom lub siab mus rau qhov ntsuas qhov ntsuas qhov ntsuas siab, 15 feeb, lub siab txo qis tsis tshaj 0.05Mpa yog tsim nyog.
6) Tom qab cov yeeb nkab seem kev ntsuas siab tau tsim nyog, ua tiav qhov kev sim siab, ua rau lub zog ntsuas siab rau 3 teev, qhov siab tsis tsawg dua 0.6Mpa, thiab lub kaw lus tsis muaj qhov tshwm sim xau yog tsim nyog .
(7) piping system kev ntsuas siab, pom qhov xau los yog siab poob qis dua tus nqi teev tseg, yuav tsum kuaj xyuas cov kav dej kom raws sijhawm, cais tawm thiab rov ntsuas lub siab raws li cov kauj ruam saum toj no, kom txog rau thaum nws ua tau raws li qhov yuav tsum tau ua.
