Dab tsi yog dej - cov tshuaj tua hluav taws?
Cov hluav taws tua hluav taws, cov khoom lag luam tshwj xeeb tsim los tua hluav taws, feem ntau ua haujlwm kom tua hluav taws sai sai, tshem tawm, lossis tiv thaiv kev sib kis ntawm hluav taws.
Dej- cov tshuaj tua hluav taws, nrog rau lawv cov txheej txheem tua hluav taws tshwj xeeb, tau dhau los ua riam phom tseem ceeb hauv kev tiv thaiv hluav taws thiab tswj. Lawv muaj AFFF (Aqueous Film-Forming Fire) extinguishing agent uas reacts nrog nitrogen los ua kom muaj npuas ntau. Thaum cov npuas dej no tau txau rau ntawm qhov chaw roj, cov dej tso tawm los ntawm cov npuas npuas kis thoob plaws cov roj, tsim cov yeeb yaj kiab dej ntom ntom. Cov yeeb yaj kiab dej no zoo thaiv kev sib cuag ntawm cov khoom siv hluav taws xob thiab huab cua, ua kom muaj hluav taws kub ceev.
Qhov zoo ntawm Dej-Raws li Cov Hluav Taws Xob Hluav Taws Xob
Physical Extinguishing Mechanism: Dej-raws li kev tua hluav taws tau tshwm sim hauv xyoo 1980s, lawv cov txheej txheem tua hluav taws raws li lub cev. Los ntawm kev tsim thiab nthuav tawm cov yeeb yaj kiab dej nyias ntawm qhov chaw ntawm cov khoom siv hluav taws xob, lawv cais cov khoom siv hluav taws xob zoo los ntawm huab cua, yog li ua tiav kev tua hluav taws sai.
Dual Action: Lub tshuab tua hluav taws tua cov dej tsis zoo los ntawm lub tshuab atomizing, uas tsis yog tsuas yog diffuses thaj chaw hluav taws thiab evaporates cua sov kom txo qhov hluav taws kub, tab sis kuj tseem txo qis cov pa oxygen concentration hauv huab cua ntawm thaj chaw combustion, zoo tiv thaiv kev kav.
Tus kheej-kev ua haujlwm cawm: Ntxiv rau kev tua hluav taws, dej- cov tshuaj tua hluav taws kuj tseem siv tau rau tus kheej- cawm hauv hluav taws. Thaum hluav taws kub hnyiab, tus neeg sawv cev tuaj yeem txau rau ntawm lub cev thiab siv rau lub taub hau, muab kev tiv thaiv hluav taws ua tiav rau cov neeg nyob hauv cov hluav taws kub zoo tib yam, thiab txo qhov kub hnyiab txawm nyob rau hauv qhov kub ntawm - ib puag ncig.
Yooj yim rau siv: Tsis tas yuav hloov pauv, lub neej txee ntev, tiv taus kev kav, thiab muaj kuab paug -dawb. Haum rau precision instruments thiab khoom siv, tsis muaj corrosive residue.
Kev siv dav: Dej- cov tshuaj tua hluav taws yog tsim rau thawj zaug hluav taws uas muaj cov khoom siv, cov kua hluav taws xob, cov khoom siv hluav taws xob, thiab roj hauv chav ua noj. Txawm li cas los xij, lawv cov kev ua tau zoo yuav tsawg dua qhov zoo tshaj plaws rau cov hluav taws kub hlau thiab hluav taws kub nyhiab tshwm sim los ntawm cov khoom uas cuam tshuam nrog dej. Tsis tas li ntawd, lawv tsis cuam tshuam los ntawm qhov chaw nyob sab hauv lossis sab nraum zoov lossis cua daj cua dub, thiab tuaj yeem siv hauv tsev, tsheb, thiab chaw ua lag luam.
Yuav siv li cas thiaj li siv tau cov dej tawm mus li - lub tshuab tua hluav taws
1.Thaum siv lub tshuab tua hluav taws uas siv tau yooj yim, ceev ceev nqa los ntawm tus kov mus rau qhov chaw tua hluav taws. Muab lub tshuab tua hluav taws kub txog li 5 meters ntawm qhov hluav taws kub (nce cua thaum siv sab nraum zoov). Tom qab ntawd, rub tawm tus pin kev nyab xeeb (tsis txhob taw tes lub taub hau tua hluav taws rau tib neeg kom tiv thaiv kev raug mob los ntawm ejection), tuav lub taub hau ntawm lub nozzle, thiab nias kom ruaj khov rau cov tshuaj tua hluav taws. Rau cov hluav taws uas muaj cov kua uas nchuav, tshuaj tsuag los ntawm sab ntawm cov nplaim taws ntawm lub hauv paus, cheb sab laug thiab sab xis thaum nce mus sai sai kom txog thaum cov nplaim hluav taws tua.
Thaum tua hluav taws uas muaj cov nplaim hluav taws kub hauv cov thawv, cheb sab laug thiab sab xis ntawm lub hauv paus ntawm cov nplaim taws. Thaum cov nplaim taws tawm ntawm lub thawv, sai sai ua ntej thiab tua cov hluav taws uas tseem tshuav. Tsis txhob tsom lub nozzle ncaj qha rau ntawm cov kua dej kom tiv thaiv kev sib tsoo thiab sib kis ntawm hluav taws.
Rau qhov hluav taws kub uas muaj cov khoom siv, tsom lub tshuab tua hluav taws ntawm qhov hluav taws kub hnyav tshaj plaws thiab cheb sab laug thiab sab xis, kom ntseeg tau tias cov hmoov tua hluav taws qhuav sib npaug npog cov khoom siv hluav taws kub kom txog thaum hluav taws tua tag nrho.
Thaum siv, tuav lub tshuab tua hluav taws kom ncaj, tsis txhob pw horizontally lossis upside down, kom paub meej tias cov tshuaj tsuag kom raug.
Tom ntej no, peb yuav sib tham txog qhov muaj pes tsawg leeg ntawm tus neeg tua hluav taws hauv dej - cov hluav taws tua hluav taws. Cov khoom no feem ntau suav nrog dej, ua lub hauv paus rau kev ua kom txias thiab tua; surfactants, uas txo cov dej nro thiab txhim khu kev nkag mus thiab ntub dej; nplaim retardants, uas inhibit combustion tshwm sim; thiab lwm yam tshuaj ntxiv xws li tshuaj tiv thaiv kab mob thiab tshuaj tua kab mob kom ntseeg tau tias kev siv ib txwm siv thiab khaws cia ntawm cov tua hluav taws hauv ntau qhov chaw.
Tsis tas li ntawd, lub neej kev pab cuam, lub neej rov qab, thiab lub neej tank dej -raws li kev tua hluav taws kuj yog cov ntaub ntawv tseem ceeb uas cov neeg siv yuav tsum tau saib xyuas.
Lub neej kev pab cuam, lub neej rov qab, thiab lub neej tank ntawm dej -raws li cov hluav taws tua hluav taws tau txhais tau meej meej. Lawv lub neej ua haujlwm feem ntau yog 6 xyoo. Raws li kev ua haujlwm ib txwm muaj, dej- cov tshuaj tua hluav taws yuav tsum tau kho lawv thawj zaug 3 xyoos txij li hnub tsim khoom, thiab tom qab ntawd xa mus rau kev kho dua tshiab txhua xyoo tom qab ntawd. Yog tias qhov chaw ua haujlwm lossis kev tiv thaiv yuav tsum hloov pauv, thawj lub sijhawm txij nkawm yuav tsum tau ua kom zoo, thiab kev pabcuam lub neej yuav tsum luv luv raws li. Tsis tas li ntawd, lub neej kev pab cuam ntawm lub tog raj kheej steel rau dej -raws li kev tua hluav taws yog 6 xyoo.
Raws li lub teb chaws tus qauv yuav tsum "General Specification for Fire Protection Facilities" (GB 55036-2022), uas tau pib siv rau lub Peb Hlis 1, 2023, cov tshuaj tua hluav taws yuav tsum tau muab pov tseg raws li cov xwm txheej hauv qab no: ntau qhov xeb ntawm lub tog raj kheej lossis pitting ntawm qhov chaw; pom tseeb deformation lossis kev puas tsuaj loj rau lub tog raj kheej; tawg nyob rau hauv lub taub hau los yog tsis muaj lub siab nyem mechanism; cov yam ntxwv tsis tsim nyog, xws li lub tog raj kheej kheej kheej; portable fire extinguishers yam tsis muaj kev cuam tshuam cov tshuaj tsuag; cov chaw tsim khoom lub npe thiab hnub tsim khoom tsis tuaj yeem lees paub; cov kab kev kho xws li soldering, brazing, los yog patching ntawm lub tog raj kheej; tau raug hlawv; thiab hnub tsim khoom mus txog lossis tshaj lub sijhawm ntau tshaj plaws (piv txwv li, 6 xyoo).
Thaum kuaj hluav taws, nws yog ib qho tseem ceeb uas yuav tsum tsis tu ncua xyuas qhov tshwm sim thiab qhov taw qhia siab ntawm cov dej - raws li cov hluav taws tua hluav taws. Yog tias pom tias lub tshuab tua hluav taws muaj teeb meem lossis tau dhau nws lub neej kev pabcuam, nws yuav tsum raug xa mus rau kev kho lossis muab pov tseg tam sim ntawd, thiab lub tshuab tua hluav taws tshiab yuav tsum tau hloov tam sim ntawd kom nws ua haujlwm tau zoo thiab kev nyab xeeb. Nyob rau tib lub sijhawm, ua raws li cov txheej txheem khiav haujlwm kom raug rau kev siv cov tshuaj tua hluav taws kuj tseem ceeb; Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua rau lawv qhov hluav taws kub -kev tua hluav taws kom tiav.
2. Ua tib zoo xyuas lub tshuab tua hluav taws lub npe kom paub tseeb tias cov chaw tsim khoom, hnub tsim khoom, qauv, thiab cov neeg tua hluav taws tua hluav taws yog qhov tseeb, ua tiav, thiab raug.
3. Tshawb xyuas lub nozzle thiab tshuaj tsuag phom rau kev thaiv, tawg, lossis deformation kom ntseeg tau tias lawv ua haujlwm zoo.
4. Ua tib zoo xyuas tus pin kev nyab xeeb thiab cov hlau lead rau kev puas tsuaj kom ntseeg tau tias lawv tsis zoo thiab ua haujlwm raug.
Kev ntsuas siab
Saib xyuas qhov ntsuas qhov ntsuas qhov ntsuas siab thiab xyuas kom meej tias nws nyob hauv thaj chaw ntsuab, qhia tias lub siab ib txwm muaj. Yog tias rab koob yog nyob rau hauv cheeb tsam liab, lub siab tsawg dhau, uas yuav cuam tshuam rau kev txhaj tshuaj ib txwm; thaum thaj tsam daj qhia tias muaj kev kub ntxhov ntau dhau, ua rau muaj kev phom sij.
Kev tshuaj xyuas cov neeg tua hluav taws
Paub meej tias tus neeg sawv cev tua hluav taws yog nyob rau hauv nws hnub tas sij hawm thiab xyuas seb puas muaj sedimentation, stratification, los yog deterioration.Tam sim no, kev ua haujlwm ntawm cov tua hluav taws yuav tsum raug kuaj xyuas: Ua cov kev ntsuam xyuas tsim nyog los xyuas seb qhov kev khiav hauj lwm mechanism yog hloov tau thiab yog tias qhib thiab kaw yog du.
Xyuas seb qhov chaw teeb tsa ntawm lub tshuab tua hluav taws puas ua tau raws li qhov yuav tsum tau ua.
