Txhua lub sijhawm, hluav taws kub nyhiab tau hem tib neeg txoj sia, thiab cov neeg cawm seej tab tom nrhiav txoj hauv kev los tshem tawm lawv. Cov hluav taws tua hluav taws tau dhau los ua cov cuab yeej tseem ceeb rau cov neeg tua hluav taws hauv kev tua hluav taws. Nyob rau hauv tsab xov xwm, peb yuav xav txog xws li hom hluav taws tua hluav taws xws li cua-emulsion, nws qhov zoo thiab qhov tsis zoo, nrog rau cov qauv nrov.
Kev piav qhia thiab nta ntawm lub tshuab tua hluav taws
Lub Emulsion Fire Extinguisher (OVE) yog qhov ua tau zoo tshaj plaws, ib puag ncig tus phooj ywg thiab nyab xeeb rau tib neeg cov khoom tua hluav taws. Nws yog ib qho kev txhim kho kev hloov kho ntawm lub tshuab cua-ua npuas dej tua hluav taws. Cov muaj pes tsawg leeg ntawm nws extinguishing sib tov, ntxiv rau surfactants, kuj muaj xws li antifreeze thiab ntau yam Cheebtsam uas ua rau kom tau ib tug aqueous emulsion. Qhov kev txhim kho no tau nthuav dav ntau yam kev siv ntawm cov cuab yeej no.
VE-tshuaj tua hluav taws, tsis zoo li lwm yam, rov siv tau dua (koj tuaj yeem rov ua dua 40 zaug). Nws qhov sib txawv tseem ceeb yog lub peev xwm los tua cov kua dej thiabCov khoom siv hluav taws xob, nrog rau kev muaj peev xwm ua haujlwm tau zoo nyob rau hauv qhov dav tshaj plaws ntawm huab cua.
Tsis tas li, cov kws tshaj lij tau sau tseg tias cov cuab yeej no muaj txiaj ntsig zoo ntawm thaj chaw tiv thaiv: rau ib qho 5-6 liter HE cov tshuaj tua hluav taws, daim duab no ncav cuag 100 square meters.
Lub Hom Phiaj thiab Scope
Vim lub cev lub cev tshwj xeeb ntawm emulsion, lub tshuab tua hluav taws no yog siv los tua ntau yam hluav taws kub:
- Class "A" thiab "B". Lub tshuab tua hluav taws yog qhov tsis tseem ceeb rau kev tua hluav taws uas tshwm sim los ntawm qhov hluav taws kub ntawm ob qho tib si khoom thiab cov kua dej combustible.
- Class "E". Lub tshuab tua hluav taws yog siv los tua cov khoom siv hluav taws xob hauv qhov hluav taws xob siab (txog 10 txhiab V).
Lub tshuab tua hluav taws OVE tuaj yeem siv tau ntau yam huab cua, nyob rau hauv qhov kub ntawm -40 txog +50 degrees.
Siv hauv cov chaw nyob thiab kev sib raug zoo nrog cov neeg coob coob, nrog rau kev tiv thaiv pej xeem thiab ntiag tug.
Tsim thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm
Tus tsim ntawm huab cua emulsion tua hluav taws (OVE) feem ntau zoo sib xws hauv cov qauv rau cov tua hluav taws uas muaj lwm yam khoom siv hauv cov khoom xyaw:
- lub tog raj kheej yog ua los ntawm cov ntawv hlau welded, uas yog cov khoom siv teeb pom kev zoo, yog li lub tshuab tua hluav taws yog qhov hnyav heev;
- raws li hom kev siv ntau dhau los siv, RE-txheej tua hluav taws tuaj yeem yog ob hom: txhaj tshuaj (siabtsim ib txheej ntawm compressed gas, uas yog pumped rau hauv lub tog raj kheej nyob rau sab saum toj ntawm lub extinguishing neeg sawv cev) los yog nruab nrog ib tug cais cartridge txuas nrog lub trigger;
- thaum lub tshuab kaw tau qhib, cov emulsion txav los ntawm lub raj siphon thiab tom qab ntawd los ntawm cov roj hmab hose mus rau lub sprayer, uas nws yog txau, tov nrog cua, mus rau combustion chaw.
Lub tog raj kheej tua hluav taws yog coated nrog cov hmoov enamel, uas ua rau nws tiv taus kev puas tsuaj thiab huab cua tsis zoo. Sab hauv ntawm lub tog raj kheej yog kho nrog cov tshuaj tiv thaiv corrosion.
Lub tshuab tua hluav taws OVE muaj cov khoom siv tshwj xeeb ntawm tus neeg tua hluav taws uas txawv ntawm lwm tus. Nws yog ib qho emulsion - aqueous tov ntawm surfactants. Xws li cov khoom sib xyaw zoo sib xyaw thiab sib xyaw nrog huab cua, uas ua rau lub dav hlau ntev ntev (qhov no tso cai rau koj nyob ntawm qhov chaw nyab xeeb ntawm qhov chaw thaum tua hluav taws) thiab kev ua haujlwm siab ntawm kev cuam tshuam ntawm combustion qhov chaw. Quenching tshwm sim tam sim ntawd thaum lub emulsion nkag mus rau hauv qhov hluav taws kub. Qhov kev tshem tawm ntawm cov txheej txheem combustion tshwm sim los ntawm qhov tseeb tias emulsion tsim ib zaj duab xis ntawm qhov chaw, nyob rau hauv uas qhov kub hnyiab tau txias. Tsis tas li ntawd, cov yeeb yaj kiab ua tau zoo tso cov khoom siv hluav taws xob uas muaj tshuaj lom rau tib neeg thiab tiv thaiv rov ua dua.
Txoj Cai Ua Haujlwm
Txhawm rau kom lub tshuab tua hluav taws tsis raug puas tsuaj ua ntej thiab ua haujlwm tau zoo, cov npe ntawm cov cai yuav tsum tau ua raws:
- rautxhawm rau nqa lub tshuab tua hluav taws ua haujlwm, nws yog qhov yuav tsum tau tawg lub foob thiab rub tawm tus pin kev nyab xeeb;
- direct lub sprayer ntawm qhov chaw tua hluav taws thiab nias lub khawm; tus nqi nrog cov emulsion ya tawm vim lub siab dhau los ntawm cov txheej txheem ntawm compressed gas.
Thaum siv lub tshuab tua hluav taws raug txwv:
- ntaus nws;
- siv balloon yog pom kev puas tsuaj;
- taw tes rau neeg.
OVE yuav tsum tau muab kaw thiab muaj cov chaw tsim khoom tau txais.
Lub cuab yeej muaj lub neej ua haujlwm ntev, tsis tas yuav rov ua ntawv pov thawj, thiab OVE lub tshuab tua hluav taws yuav tsis rov them dua 10 xyoo (40 recharges raug tso cai rau tag nrho lub neej kev pabcuam).
Txhawm rau kuaj xyuas kev noj qab haus huv ntawm cov cuab yeej no, nws tsuas yog txaus los ntawm qee lub sijhawm kom pom kev tswj xyuas qhov kev nyeem ntawm qhov ntsuas ntsuas ntsuas.
Qhov zoo thiab qhov tsis zoo
Lub OVE tua hluav taws, vim nws qhov tshwj xeeb muaj pes tsawg leeg - emulsion, ua ke cov khoom zoo ntawm cov dej thiab cua-ua npuas dej tua hluav taws, thaum tsis muaj qhov tsis zoo uas cov cuab yeej no muaj. Nws Cov txiaj ntsig:
- kev ua tau zoo tshaj plaws thiab ntau yam piv rau lwm hom kev tua hluav taws;
- kev nyab xeeb ib puag ncig: tsis muaj mob rau tib neeg kev noj qab haus huv, thiab tseem tsis ua rau cov khoom puas tsuaj hauv hluav taws, tsis ua rau ib puag ncig;
- thaj chaw tiv thaiv loj;
- thaum quenching tsis tsimhmoov av cov ntsiab lus, yog li tsis cuam tshuam kev pom;
- tsis nce cov pa roj carbon dioxide thaum ignited hauv ib qho chaw kaw;
- koj tuaj yeem pib tua tam sim ntawd, yam tsis muaj cov cuab yeej tiv thaiv tus kheej, nyob ntawm tib neeg, txoj cai thaum khiav tawm;
- muaj peev xwm tua cov khoom hauv qab hluav taws xob;
- muaj peev xwm ntawm daim ntawv thov ntawm qhov tsis zoo ambient kub;
- ntev kev pab cuam lub neej.
Qhov tsis zoo tseem ceeb yog tus nqi siab. Tab sis nws yog kev ncaj ncees los ntawm qhov ua tau zoo ntawm kev tua hluav taws. Cov cuab yeej tuaj yeem hloov ntau lub kaum os ua npuas ncauj analogs thaum lub sijhawm ua haujlwm.
Chaw tsim khoom thiab qauv
Cov thawj coj ntawm cov khoom lag luam nrov yog cov tuam txhab Lavxias Rusintek, Bontel, Samurai, NPO Pulse. Cov tuam txhab lag luam no muaj ntau yam qauv uas sib txawv ntawm qhov hnyav ntawm qhov ntau ntawm 2 txog 50 kg.
Lub tog raj kheej me me (2 lossis 4 kg) yog qhov zoo tagnrho rau lub tsheb sab hauv. Yam ntxwv ntawm OVE tua hluav taws:
- ua haujlwm siab - 1.85 MPa;
- siv qhov kub ntawm -40 txog +50 ° C;
- dav hlau ntev - tsis pub tsawg dua 12 vib nas this;
- hluav taws tua hluav taws - 2A (chav kawm A), 55V (chav B), mus txog 1000V (chav kawm E).
Lub tog raj kheej ntawm 8, 10, 40 thiab 50 kg yog feem ntau ntsia hauv thaj chaw loj - warehouses, hangars, thiab lwm yam. Lub tog raj kheej nrog lub siab loj ntawm tus nqi, los ntawm 10 kg thiab siab dua, yog txawb, uas yog, lawv tau nruab nrog lub trolley rauyooj yim siv. Cov qauv nrov tshaj plaws rau kev siv hauv tsev yog tsib- thiab rau-kilogram tua hluav taws.
Ntawm cov qauv tuaj txawv teb chaws, lub cuab yeej los ntawm MiniBombero (Spain) nyiam mloog, uas muaj qhov loj me me, nrog tus nqi ntim ntawm 250 ml.
Kingsway Industries TRI-MAX cov hluav taws tua hluav taws yog qhov txawv ntawm qhov muaj rooj plaub rau khaws cov cuab yeej. Cov qauv no yog lub teeb yuag thiab yooj yim siv.
Cov hluav taws tua hluav taws los ntawm lub tuam txhab British Angus Fire kuj paub thoob plaws ntiaj teb. Lawv txawv ntawm qhov hnyav thiab ntim, tab sis txhua yam khoom siv ua haujlwm zoo ntawm kev tua cov khoom tib yam.
Nws tuaj yeem hais tau tias lub tshuab tua hluav taws yog qhov tseem ceeb ntawm kev ruaj ntseg ntawm txhua qhov chaw. Cov kev cai tsim kom muaj qhov yuav tsum muaj ntawm cov cuab yeej no, nrog rau nws lub sijhawm kuaj xyuas thiab rov them dua.
