Nyob rau hauv hluav taws sprinkler systems, lubK-factoryog ib qho tseem ceeb tshaj plaws ntawm cov txheej txheem uas cuam tshuam ncaj qha rau cov dej tawm, kev tsim qauv, thiab kev tua hluav taws. Txawm hais tias koj yog ib tus neeg cog lus, tus neeg muag khoom, lossis tus engineer project, kev nkag siab txog K-factor yuav pab koj xaiv lub taub hau sprinkler zoo thiab xyuas kom ua raws li cov qauv thoob ntiaj teb.
K-Factor yog dab tsi?
K-factor (pas coefficient) sawv cev rau kev sib raug zoo ntawmtus nqi ntwsthiabsiabnyob rau hauv ib tug hluav taws sprinkler. Nws qhia tias dej ntau npaum li cas tus sprinkler tuaj yeem xa tau ntawm lub siab.
Q=KPQ=K \\sqrt{P}Q=KP
Qhov twg:
Q= Tus nqi ntws (GPM lossis L/min)
K= K-factor (pas coefficient)
P= Siab (psi lossis bar)
Hauv cov ntsiab lus yooj yim, qhov siab dua K-factor txhais tau tias dej ntau dua tawm ntawm tib lub siab.
Vim li cas K-Factor tseem ceeb?
1. Txiav txim qhov muaj peev xwm tawm dej
K-factor ncaj qha tswj kom muaj dej ntau npaum li cas los tswj lossis tua hluav taws.
Me K-factor → qis ntws tus nqi
Loj K-factor → siab dua tus nqi ntws
2. Impacts System Design
Cov kws tsim khoom siv K-factor thaum xam cov kev cai hydraulic. Nws cuam tshuam:
Cov yeeb nkab loj
Pump muaj peev xwm
Qhov system siab xav tau
Xaiv qhov tsis ncaj ncees lawm K-factor tuaj yeem ua rau muaj kev tiv thaiv hluav taws tsis txaus lossis tsis tsim nyog tus nqi siab.
3. Muaj feem cuam tshuam txog kev tua hluav taws
Cov hluav taws kub sib txawv xav tau cov dej sib txawv.
Teeb pom kev zoo → me K-factor (eg, K5.6)
Kev phom sij → nruab nrab K-factor
Siab txaus ntshai / warehouse → loj K-factor
Common K-Factor Values and Applications
| K-Qhov xwm txheej | Daim ntawv thov |
|---|---|
| K5.6 | Chaw ua haujlwm, tsev so, tsev lag luam |
| K8.0 | Kev lag luam chaw |
| K11.2 | Warehouses, chaw cia khoom |
| K14+ | Siab -kev pheej hmoo hluav taws kub |
Ntawm cov no,K5.6yog ib qho ntawm cov qauv siv dav tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv cov qauv kev lag luam tiv thaiv hluav taws.
K-Txoj kev sib raug zoo thiab siab (Piv txwv)
Yog hais tias lub sprinkler muaj K-factor ntawm 5.6:
Ntawm 1 bar siab → qis ntws
Thaum siab dua → ntws ntau dua
Vim tias ntws nce nrog covsquare root ntawm siab, nce siab tsis ua ob npaug ntawm qhov ntws - nws nce nws proportionally.
Yuav Ua Li Cas Xaiv Txoj Cai K-Factor
Xaiv qhov tseeb K-factor nyob ntawm ntau yam:
1. Kev faib hluav taws kub nyhiab
Ua raws li cov qauv xws li NFPA los txiav txim siab txog qib kev phom sij.
2. Kev Tsim Kho Cov Cai
Xav txog kev siv dej, kav dej, thiab lub peev xwm twj tso kua mis.
3. Cov qauv ntawv pov thawj
Ib txwm xaivFM-pom zoo los yog UL- npe cov tshuaj tsuag dejkom ua raws li kev ntseeg tau.
4. Daim ntawv thov Scenario
Chaw ua haujlwm → me K-factor
Warehouses → loj K-factor
Muaj kev pheej hmoo → siab - muaj peev xwm sprinklers
K-Factor vs Orifice Size
K-factor yog ze ze rau qhov loj ntawm lub qhov dej ntws:
Loj dua → siab dua K-factor
Qhov me me → qis K-factor
Txawm li cas los xij, kev ua tau zoo kuj nyob ntawm kev tsim thiab ntawv pov thawj, tsis yog lub cev loj xwb.
Kev pom kev lag luam: Vim li cas K5.6 thiaj li nrov
K5.6 sprinkler taub hau yog dav siv vim lawv muaj:
Balanced dej ntws thiab siab xav tau
Compatibility nrog cov kav dej txheem
Tus nqi -kev txhim kho zoo
Lawv yog cov zoo tagnrho rau feem ntau cov lag luam thiab lub teeb kev lag luam daim ntaub ntawv, ua rau lawv ib tug thoob ntiaj teb tus qauv kev xaiv.
Xaus
K-factor yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob tua hluav taws, cuam tshuam cov dej ntws, kev tsim qauv, thiab kev tiv thaiv hluav taws tag nrho. Kev nkag siab txog nws ua haujlwm li cas tso cai rau cov kws tsim khoom thiab cov neeg yuav khoom los txiav txim siab, ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo.
