Cov kev txiav txim siab tseem ceeb rau PPP cov khoom siv hluav taws xob network rau hauv vaj tse siab
Apr 17, 2025
Cov khoom siv xaiv thiab siab ntsuam xyuas cov tseev kom nyab xeeb
PPR (Polypropylene Random Copolymer) kav tau dav siv nyob rau hauv high-et siv cov tshuab hluav taws xob siab vim lawvcorrosion tsis kam, thermal ruaj khov, thiab yooj yim ntawm kev teeb tsa{{0. Txawm li cas los xij, xaiv qhov tseebSiab Ntsuam (PN)Yog qhov tseem ceeb:
PN20 (2.0 MPa)Yog qauv rau cov tsevTsawg dua los yog sib npaug rau 100m
PN25 (2.5 MPA)Yuav tsum muaj rau100–200mKev qauv
PS32 (3.2 MPA)Tej zaum yuav tsum muaj rauultra-high-rise buildings (>200m)
Cov kev txiav txim ntxiv:
✔ Them Nyiaj Kho Mob Thermal(Ppr nthuav tawm0.15 mm / mth degree)
✔ UV KujRau cov piping nthuav tawm
✔ Antimicrobial-qib PPRRau Cov Dej Muaj Peev Xwm
Kev Ntsuas Siab Hydraulic Thiab Boosy Tshuab
Cov Vaj Tse muaj kev cia siab xav tauSiab ZoningTxhawm rau tiv thaiv kom ntau dhau ntawm cov plag tsev qis thaum ua kom muaj kev txaus ntws txaus:
Raug kev sib tsoo siab
| Qhov chaw | Qhov siab ntau | Txoj Kev Tswj Siab Siab |
|---|---|---|
| Tsawg cheeb tsam | Plag tsev 1-10 | Cov Khoom Siv Hluav Taws Xob Ncaj Ncees (0.3-0.5 MPa) |
| Nruab nrab cheeb tsam | Plag tsev 11-30 | Cov twj tso hluav taws xob nruab nrab (0.6-0.8 mpa) |
| Thaj Chaw Nyob | Plag tsev 31+ | Ntau theem sib txawv-ceev twj (1.0-1.2 mpa) |
Cov Ntsiab Lus Tseem Ceeb:
Siab-Txo Cov Li Qub (PrVs)Yuav tsum tau nruab rau ntawm thaj chaw hloov chaw
Surge ntesYuav tsum tau tiv thaiv cov rauj rauj hauv txoj sia ntsug
Siab nyem li qubYuav tsum tau teeb tsa ntawm1.5 × kev ua haujlwm siab
Kev khiav yeeb nkab coj thiab cov qauv txheej txheem txhawb cov tshuab
Raws caiCov yeeb nkab kev thiab txhawb nqaYog qhov tseem ceeb kom haumThermal nthuav dav, Seismic kev txav, thiab lub tsev hais haum:
Txhim kho cov kev coj ua zoo tshaj plaws
✔ Ntsug risersYuav tsum sivCoj kev nthuav dav nthuav davTxhua10 plag tsev
✔ Kab rov tav cegYuav tsum muaj1% nqes havRau kev pleev tshuaj thaum lub sijhawm tu
✔ Txhawb placingYuav tsum ua raws:
Dn20-dn50 kav dej: 1.0m kev sib tw
DN63-DN110 PHEM: 1.5m kev sib ntsib
>DN125 kav dej: 2.0m spacing
Cov kev txiav txim siab seismic:
Saj zawg zog txuasNtawm cov txheej txheem sib koom tes
Txwv clampsTxhawm rau tiv thaiv cov yeeb nkab nplawm thaum av qeeg
Thermal rwb thaiv tsev thiab kev ntsuas hluav taws xob ntsuas
PPR kav hauv High-Rises xav tauThermal rwb thaiv tsevTxhawm rau tiv thaivThaum tshav kub kub poob rau hauv cov dej kub thiab hws hauv cov kab dej txias:
Rwb thaiv tsev cov khoom xaiv
| Daim ntawv thov | Pom zoo rwb thaiv tsev | Tuab (mm) |
|---|---|---|
| Dej Kub (60 Degree +) | Kaw-Cell Elastomic Ua npuas ncauj | 20–25 |
| Dej txias (<20°C) | Polyethylene Ua Npuas Ncauj | 15–20 |
| Kev tiv thaiv hluav taws | Cov Khoom Siv Hluav Taws Xob (A1 Hluav Taws-rated) | 30–50 |
Cov tswv yim txuag txuag ntxiv hluav taws xob:
✔ CUA KUB TSHUAB Rov QabHauv cov loops recirculation
✔ Ntse thermostatic sib xyaw li qubTxhawm rau txo cov khib nyiab
✔ Yeeb Nkab-Cov Yeeb Nkab TsimRau Kev Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
Kev Tu thiab System Rov Qab
Kev nce PPR tau nce siab yuav tsum teeb tsaKev Tu Me Nyuam Yooj YimThiabTsis muaj kev sib deev tsis zoo:
Tseem ceeb saib xyuas nta
✔ Tshuaj xyuas ChambersNtawm txhuaPem teb 5
✔ Kev rho tawm li qubRau txhuaNtsug riser ntsug thiab kab rov tav
✔ Cov chaw tso dej ntwsNtawm cov ntsiab lus qis rau cov kab ke
Cov kev xav tau dua tshiab
Dual pub risersRau cov chaw tseem ceeb (tsev kho mob, tsev so)
Tsis Siv Neeg Hloov Li QubThaum cov yeeb nkab tsis ua haujlwm
Backup Siab Tso Tsheb Hlau LuamRau cov dej kub ceev
