Cov ntsiab lus
Cov tshuab ua npuas ncauj yog tsim los txwv kev puas tsuaj hluav taws hauv ntau qhov kev sib tw thiab kev pheej hmoo siab. Tshwj xeeb, ua npuas ncauj- dej system yog ib qho tshwj xeeb ntawm cov yeeb nkab txuas nrog lub hauv paus ntawm cov npuas dej thiab cov dej. Lub kaw lus tseem yuav tsum muaj cov cuab yeej tso tawm tsim nyog los tswj thiab / lossis tua hluav taws kub hauv chav A thiab Chav B feem ntau. Foam concentrates yog tov nrog dej thiab huab cua los tsim ib daim pam ua npuas ncauj uas ua rau hluav taws kub los ntawm kev txiav cov pa oxygen. Daim pam no kuj ua rau cov roj cua txias thiab tiv thaiv kev tso tawm ntawm cov vapors uas muaj hluav taws kub, inhibiting re- ignition.
Ua npuas ncauj- cov tshuab dej tau tsim los faib ua npuas dej- cov dej daws rau thaj chaw muaj kev phom sij tshwj xeeb hauv qhov chaw tiv thaiv. Piv txwv li, cov chaw muaj xws li cov chaw tsim hluav taws xob, hloov hluav taws xob, Farm Tank, thiab aircraft hangars. Tshwj xeeb lawv kuj tseem npog thaj chaw uas muaj hluav taws kub -kua hluav taws tuaj yeem tshwm sim, xws li refineries. Thaum cov nplaim hluav taws kub hnyiab tau, nws yog ib qho tseem ceeb uas yuav tsum siv lub tshuab tua hluav taws uas muaj peev xwm npog tag nrho cov hluav taws, tsis tas yuav kis mus ntxiv. Nyob rau hauv cov ntaub ntawv ntawm roj av-raws li cov kua, piv txwv li, dej yog me ntsis nqi vim hais tias nws yog denser tshaj cov roj, thiab yog li tam sim ntawd ntws hauv qab nws, ces tus supposed tus neeg sawv cev evaporates vim cua sov, ua rau cov roj hlawv mus ntxiv, thiab sai dua. Nyob rau hauv cov xwm txheej no, ua npuas ncauj lossis qhuav tshuaj tua hluav taws tua hluav taws yog cov kev xaiv tsim nyog.
Daim pam no kuj ua rau cov roj cua txias thiab tiv thaiv kev tawm ntawm cov vapors uas tuaj yeem tawg, inhibiting re-ignition.
Lub tshuab ua npuas ncauj ib txwm muaj cov khoom hauv qab no uas tau sim, pom zoo thiab / lossis teev ua ke:
●Ua npuas ncaujzais zis tank
●Proportioner
●Ua npuas ncauj concentrate
●Discharge device - Nozzles, Foam Monitor, thiab lwm yam.
Tsis tas li ntawd, cov yam ntxwv ntawm qee cov khoom siv hluav taws xob tuaj yeem xav tau ntau dua thiab cov ua npuas ncauj tshwj xeeb ua kua concentrates. NFPA 11 thiab EN13565-2 muaj cov kev cai rau cov tshuab ua npuas dej, nrog rau cov txheej txheem ua npuas dej kuj pom muaj nyob hauv NFPA 13, NFPA 16.
Daim ntawv thov
Qhov zoo ntawm Foam Mist Systems
Txo cov dej puas tsuaj:
Muab piv rau cov tshuab siv tshuaj pleev ib ce, cov tshuab ua npuas dej feem ntau siv dej tsawg, txo cov dej puas tsuaj rau cov khoom siv lossis cov khoom siv.
Siv tau rau hauv Flammable Liquid Fires:
Cov tshuab ua npuas ncauj yog qhov tshwj xeeb zoo- haum rau kev sib ntaus sib tua hluav taws uas muaj cov kua dej uas muaj hluav taws kub, qhov uas ua rau cov npuas dej yog qhov tseem ceeb heev.
Cooling thiab Vapor Mitigation:
Ua Npuas Ncauj Systems tuaj yeem siv tau rau ntau yam kev teeb tsa, suav nrog cov chaw tsim khoom, dav hlau hangars, thiab thaj chaw nrog cov cuab yeej rhiab heev.
Environmentally Firendly:
Qee Lub Tshuab Ua Npuas Ncauj siv fluorine -dawb foams, uas yog tsim los ua ib puag ncig zoo dua li ib txwm ua npuas ncauj.
Hom Foam Mist Systems
Tsawg Expansion Foam:
Hom Ua Npuas Ncauj no muaj qhov sib piv qis (2: 1 ~ 20: 1), txhais tau tias Ua Npuas Ncauj Muaj feem ntau ntawm cov dej. Nws yog qhov tsim nyog rau cov hluav taws kub uas muaj cov khoom siv hluav taws xob zoo tib yam thiab qee cov kua hluav taws xob.
High Expansion Ua Npuas Ncauj:
This type of foam has high expansion ratio(>200: 1), lub ntsiab lus nws nthuav dav, tsim kom muaj qhov ntim loj ntawm cov npuas dej, Nws yog qhov tsim nyog rau kev sau qhov chaw loj thiab tua hluav taws hauv qhov chaw kaw.
Medium Expansion Foam:
Hom npuas no muaj qhov nruab nrab nthuav dav (20: 1 ~ 200: 1). Nws muaj qhov sib npaug ntawm cov ntaub ntawv thiab dej.
Compressed Air Foam (CAF):
CFS system siv compressed cua sib xyaw nrog Foam-Dej los tsim ua npuas ncauj nrog cov qauv tshwj xeeb uas tuaj yeem khi rau saum npoo thiab muab kev tua hluav taws zoo hauv ib puag ncig kev phom sij.
