● Yuav tsum muaj lub qhov tswj kom tswj tau dej ntws
● Kev saib xyuas ob zaug ntawm lub ntsuas siab ua haujlwm thiab lub ntsuas siab ntawm cov yeeb nkab tseem ceeb ntawm lub kaw lus
Cov Kev Cai Saib Xyuas Kev Nyuaj Siab:
● Lub ntsuas siab yuav tsum tau nruab nrog lub cuab yeej buffer (pom zoo kom siv diaphragm buffer)
● Lub qhov ntsaws ntsaws tau teeb tsa rau pem hauv ntej ntawm lub cuab yeej buffer rau kev saib xyuas yooj yim
● Qhov ntsuas siab ntau yam: 2.0-2.5 npaug ntawm qhov ua haujlwm siab ntawm lub kaw lus
2. Cov lus qhia txog kev teeb tsa rau cov khoom siv tswj dej
Cov Kev Cai Rau Kev Taw Qhia:
● Cov qhov dej ntsuas/cov qhov dej tswj ntau yam yuav tsum sib xws nrog cov dej ntws.
● Kev sib txuas ntawm flange yog qhov pom zoo kom ntseeg tau tias nruj
Cov ntsiab lus ntawm kev teeb tsa lub ntsuas siab:
● Cov khoom siv uas tiv taus xeb (304 stainless hlau lossis tooj liab alloy) yuav tsum siv rau cov khoom siv buffer
● Qhov siab ua haujlwm ntawm lub qhov ntsaws yuav tsum yog 1.2-1.5m ntawm hauv av
3. Kev tsim kho txoj kev zoo tshaj plaws ntawm cov yeeb nkab nqus
Kev teeb tsa ntawm cov cuab yeej lim dej:
● Cov yeeb nkab nqus yuav tsum tau nruab nrog lub lim pob tawb (qhov loj me ≤ 3 hli)
● Lub lim dej yuav tsum tau nruab nrog lub cuab yeej ceeb toom sib txawv
Tsim los rau kev yooj yim ntawm kev saib xyuas:
● Lub lim dej yuav tsum tau nruab nrog lub raj xa dej bypass thiab lub interface ntxuav sai
● Pom zoo kom siv lub lim uas tshem tau
4. Kev tiv thaiv rau cov yam ntxwv hydraulic
Kev xaiv txo qis eccentric:
● Yuav tsum siv cov reducers txheem (raws li SH/T 3406)
● Lub kaum sab xis ntawm lub reducer yuav tsum yog ≤8° kom tiv thaiv kev hloov pauv sai sai hauv kev tiv thaiv hauv zos
Kev Txhim Kho Kev Nqus Dej:
● Qhov ntev ntawm cov yeeb nkab ncaj ua ntej thiab tom qab lub reducer yuav tsum yog ≥ 5 npaug ntawm cov yeeb nkab txoj kab uas hla
● CFD simulations raug pom zoo kom paub tseeb tias qhov kev faib tawm ntawm cov nqi ntws
5. Cov Lus Ceeb Toom rau Kev Ua Haujlwm
Kev ntsuam xyuas kev ntxhov siab:
● Qhov kev sim siab ntawm lub kaw lus yuav tsum yog 1.5 npaug ntawm qhov siab ua haujlwm
● Lub sijhawm tuav tsis tsawg dua 2 teev
Cov Txheej Txheem Flushing:
● Yuav tsum tau ua kom cov tshuaj pickling passivation ua ntej kev teeb tsa lub kaw lus
● Tus nqi ntws tawm yuav tsum yog ≥ 1.5m/s
Cov Qauv Txais:
● Qib tseeb ntawm lub ntsuas siab yuav tsum tsis txhob qis dua 1.6
● Lub siab sib txawv ntawm lub lim yuav tsum yog ≤ 0.02MPa
6. Cov txheej txheem kev qhia tshwj xeeb no tau suav nrog hauv "Cov Lus Qhia Txog Kev Siv Dej Tua Hluav Taws thiab Cov Tshuab Tua Hluav Taws" GB50974, thiab nws raug pom zoo kom ua qhov kev tshuaj xyuas HAZOP ua ke nrog cov haujlwm tshwj xeeb, tsom mus rau cov ntsiab lus txaus ntshai hauv qab no:
● Kev pheej hmoo ntawm kev ntws rov qab ntawm cov xov xwm vim yog qhov tsis ua haujlwm ntawm cov qhov dej kuaj xyuas
● Kev pheej hmoo ntawm kev tsis muaj dej txaus vim yog cov lim dej txhaws
● Kev pheej hmoo ntawm kev ua haujlwm siab dhau vim yog lub ntsuas siab tsis ua haujlwm
● Kev pheej hmoo ntawm kev poob siab hydraulic los ntawm kev teeb tsa tsis raug ntawm cov reducers
Nws raug pom zoo kom siv cov txheej txheem saib xyuas digital, teeb tsa cov ntsuas siab, cov ntsuas ntws thiab cov ntsuas kev co, thiab tsim kom muaj lub tshuab tswj hwm chav twj tso kua hluav taws ntse kom ua tiav kev saib xyuas qhov xwm txheej tiag tiag thiab ceeb toom txog qhov txhaum.
