Esfr (Thaum Ntxov Kev Teb Cov Lus Teb Cov k - cov ntsiab lus tseem ceeb hauv cov dej tiv thaiv hluav taws xob, kom muaj cov dej pov tseg es

1. Kev txhais thiab cov mis

Lub k - qhov tseeb ntawm lub taub hau sprinkler sawv cev nws cov orifice loj thiab ntws cov yam ntxwv. Nws yog xam siv cov qauv:
K = Q / √P
Qhov twg:

Q=} txaus tus nqi (GPM)

P=} qhov siab (PSI)
Cov mis no qhia tau tias cov k {- qhov tseeb yog ncaj qha rau tus nqi txaus rau lub hauv paus xwm fab ntawm lub siab. Ib qho siab dua k- qhov tseeb txhais tau tias yog orified loj dua, tso cai ntau cov dej ntws los ntawm tus kais tsuag dej ntawm lub zog.

2. Ntau ntawm esfr k - yam

ESFrinklers yog tsim nrog k - yam tseem ceeb xws li ntawm 11.2 txog 303.6, haum ntau qhov siab, thiab cov hluav taws kub. Hom K -} yam muaj xws li:

K =11.2}: qhov tsawg kawg nkaus k-} qhov tseeb tau teev los ntawm NFPA 13 rau cov ntawv thov ESFR.
K {=14.0, k {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
K {=22.4, k {{}}}}}}}}}}}}}}}}}} Cov khoom siv khaws cia ua kom muaj zog, qhov twg ntau dua cov dej ntom ntom.

Piv txwv li, Ty Bend - 34 rpm / barÃ ib puag ncig muaj hluav taws kub nyob rau ib puag ncig kev phom sij.

3. Qhov tseem ceeb hauv kev tsim qauv

K {- qhov tseeb ua si lub luag haujlwm tseem ceeb hauv cov tshuaj tsuag hydraulic, cov yeeb nkab sizing, thiab dej ua rau cov hluav taws tiv thaiv hluav taws. Cov kws ua engineers siv k - yam rau:

Xyuas kom muaj cov dej ntws txaus: ntau dua k -}}}}}} yam dej kom ncav tau hluav taws, tseem ceeb rau kev nqes los ntawm kev cuam tshuam hluav taws kub loj lossis nrawm.
Txhim kho cov kev xav tau siab: qib siab dua!
Match Cov Teeb Meem: K {- yam uas tau xaiv raws li hom khoom (piv txwv, cov ntawv, lossis cov nplaim taws) thiab qhov siab nthab kom muab kev tiv thaiv zoo.

Piv txwv li, ib lub tsev rau khoom uas muaj siab {{0} piled cia cov dej spastics nrog 25.2 kom xa cov dej ntws tawm txaus thiab nkag mus rau kev tsim txom cov hluav taws sai.
