ESFR Hom Hluav Taws Xob Sprinkler
forede® hom Qhov txiaj ntsig tseem ceeb ntawm ESFR sprinklers nyob rau hauv lawv lub peev xwm los ntes thiab tswj hluav taws thaum ntxov, txo qis kev puas tsuaj thiab txhim kho kev nyab xeeb rau tib neeg thiab khoom. Lawv cov lus teb ceev ceev pab kom muaj hluav taws kub ua ntej lawv tuaj yeem kis tau, ua kom muaj kev nyab xeeb dua thiab txo qis kev cuam tshuam kev lag luam.
ESFR sprinklers yog engineered nrog rhiab heev thaum tshav kub kub- teb cov ntsiab lus uas tam sim ntawd ua rau cov dej tawm. Qhov kev ua kom ntxov ntxov no, ua ke nrog cov dej ntws muaj zog, ua kom cov hluav taws kub thiab tiv thaiv rov qab - ignition. Lawv cov qauv tsim txhawb kev tua hluav taws zoo yam tsis tas yuav tsum muaj kev tiv thaiv hluav taws ntxiv lossis cov khoom siv hluav taws xob nyuaj.
Kev lees paub dav dav rau lawv txoj kev ntseeg tau thiab kev ua tau zoo, ESFR cov tshuaj tua hluav taws yog qhov kev xaiv zoo rau kev txiav - ntug kev nyab xeeb kev daws teeb meem. Los ntawm kev sib koom ua ke ESFR sprinklers rau hauv kev tiv thaiv hluav taws, kev lag luam qhia kev cog lus ruaj khov rau kev nyab xeeb thiab kev tiv thaiv, txhawb kev thaj yeeb nyab xeeb thiab tiv thaiv cov khoom muaj nqis.
Hauv cov ntsiab lus, ESFR cov hluav taws kub hnyiab sawv cev rau qhov kev vam meej hauv kev tiv thaiv hluav taws, muab kev tshawb pom ntxov, cov lus teb sai, thiab muaj zog tiv thaiv los tsim kom muaj kev nyab xeeb rau txhua tus.
Q1: Dab tsi txhais tau tias ESFR sprinkler system? Yuav ua li cas nws txawv ntawm cov pa sprinklers?
A1:
ESFR (Early Suppression Fast Response) cov tshuab yog tsim los rau siab -cov chaw cia khoom. Cov kev sib txawv tseem ceeb muaj xws li:
Teb ceev: Cov ntsiab lus cua sov nrog Lub Sijhawm Teb Index (RTI) Tsawg dua lossis sib npaug rau 28 (m·s) ^ 0.5, 2-3 × sai dua li cov txheej txheem sprinklers
Kev Txhaum Cai: Direct hluav taws nkag los ntawm siab -flow (K=25.2) optimized droplets (0.9-1.2mm nruab nrab txoj kab uas hla) es tsis muaj ntim
Qhov siab muaj peev xwm: Muaj ntawv pov thawj rau qab nthab txog li 45 ft (13.7m) ib NFPA 13 vs . 30 ft (9m) rau cov tshuab tsoos
Q2: Puas yog ESFR cov tshuab tsim nyog rau kev cia txias lossis cov khoom siv phom sij?
A2:
Pom zoo daim ntawv thov:
Txias Cia: Yuav tsum tau qhuav- hom / ua ntej- cov tshuab ua haujlwm nrog cov tshuaj glycol (xws li Dutch -13℃F / -25℃case study)
Khoom siv phom sij: FM-pom zoo tshwj xeeb sprinklers nrog 30% nce ceev rau Class III/IV khoom
Txwv tsis pub siv:
Cov chaw khaws cov ntaub ntawv pyrophoric (xws li nitrocellulose)
Warehouses tshaj 50 ft (15m) qab nthab qhov siab
UL 199: Tsis siv neeg Sprinklers rau kev tiv thaiv hluav taws
Q3: Kev saib xyuas tshwj xeeb?
A3:
Peb lub hlis twg: Alarm valve test (lub sij hawm teb Tsawg dua lossis sib npaug li 5 vib nas this)
Txhua xyoo:
Strainer tu (tshem ntau dua lossis sib npaug ntawm 0.04 "(1mm) cov khib nyiab)
Siab sensor calibration (± 2 PSI kam rau ua)
5-Xyoo Yuav Tsum Tau: Thermal element hloov (txawm tsis siv)
