Cov chav roj teeb tsim cov roj hydrogen, thiab cov roj teeb sib txawv tsim cov roj hydrogen rau ntau yam. Txawm hais tias nws yog ib txwm siv lub valve- tswj cov hlau lead- cov roj teeb kua qaub lossis cov roj ntsha lithium -ion roj teeb, hydrogen gas yog tsim nyob rau hauv tej yam kev mob, yog li ib tug hydrogen detector yog yuav tsum tau.
1.Lead-acid roj teeb:
Nyob rau hauv ib txwm muaj xwm txheej: Nyob rau hauv ib txwm float charging lub xeev, roj tsawg heev yog generated, thiab oxygen recombination tshwm sim nyob rau hauv lub roj teeb.
Qhov xwm txheej txaus ntshai: Thaum overcharged, cov electrolyte (dilute sulfuric acid) yuav raug electrolyzed, tsim cov roj hydrogen thiab oxygen ntau. Yog hais tias lub roj teeb puas lawm los yog puas, qhov kev nyab xeeb valve tsis ua hauj lwm, los yog qhov cua nyob rau hauv lub tshuab chav tsev tsis zoo, cov gases yuav nyob rau hauv ib tug confined qhov chaw.
2.Lithium-Ion roj teeb:
Thaum thermal runaway tshwm sim (xws li overcharging, nyob rau hauv luv luv Circuit Court, sab nraud kub siab, thiab lwm yam), complex tshuaj tshuaj tiv thaiv yuav tshwm sim nyob rau hauv lub roj teeb, decomposing thiab tsim ntau yam flammable gases, uas hydrogen yog ib tug ntawm cov tseem ceeb Cheebtsam, thiab nws yog generated ntawm tus ceev heev npaum li cas, ua rau muaj kev pheej hmoo siab. Nyob rau hauv txhua rooj plaub, hydrogen yog heev flammable thiab tawg.
Qhov tawg txwv ntau ntawm hydrogen hauv huab cua yog dav heev (4.0% - 75.0% vol). Thaum qhov concentration ntawm hydrogen nyob rau hauv cov huab cua nce mus txog 4%, nws yuav tawg heev thaum ntsib me me sparks, hluav taws xob zoo li qub, siab - kub qhov chaw, los yog txawm hloov arcs. Tib neeg lub siab tsis tuaj yeem kuaj pom qhov xau thiab sib sau ntawm hydrogen. Hydrogen yog cov pa roj uas muaj qhov ntom ntom qis tshaj plaws, thiab nws yooj yim khaws cia rau saum toj, cov ces kaum, thiab qab nthab ntawm qhov chaw kaw lossis ib nrab-cov chaw kaw, tsim kom muaj qhov chaw tawg.
Kev Nyab Xeeb Kev Nyab Xeeb: Cov chav roj teeb feem ntau yog qhov chaw kaw nrog qhov muaj peev xwm txwv qhov cua. Yog tias cov roj hydrogen generated tsis tuaj yeem ua kom sai thiab ua tau zoo, nws cov concentration yuav nce ntxiv. Thaum nws mus txog qhov txwv tsis pub tawg (4%), txhua qhov hluav taws xob tuaj yeem ua rau muaj kev puas tsuaj loj thiab hluav taws kub, ua rau cov khoom puas tsuaj, raug mob, thiab kev cuam tshuam kev lag luam. Lub teb chaws thoob ntiaj teb tswj hwm kev teeb tsa ntawm hydrogen concentration saib xyuas thiab cov khoom siv tswb hauv cov hlau lead-cov roj teeb acid chav / txee / cheeb tsam, uas yuav tsum tau ua ke nrog lub qhov cua.
3.Yuav ua li cas xaiv lub tshuab ntsuas hydrogen?
Hydrogen Gas Detector rau chav roj teebKev ntsuas ntau los ntawm cov uas kuaj pom cov lej ntawm 0-1000ppm / 0-2000ppm, rau cov uas kuaj pom qhov siab ntawm 0-100% LEL, uas yog sib npaug rau 0-4% vol. Qhov qis dua qhov txwv (LEL) rau hydrogen yog 40,000 ppm (4%). Kev ceeb toom ntxov yog muab thaum qhov kev xav tau nce mus txog 1% LEL (400 ppm), tso cai rau lub sijhawm txaus los ntsuas (xws li kev tshuaj xyuas thiab ua kom qhov cua zoo dua) los tiv thaiv cov concentration ntawm kev nce mus rau theem txaus ntshai lossis tawg. Lub tswb nrov ntawm 1000 ppm (0.1%), uas nyob deb ntawm qhov qis qis qis, ua haujlwm ceeb toom kev nyab xeeb.
Portable hydrogen detectors nrog ntau yam ntawm 0-1000ppm los yog 0-2000ppm, uas yog rhiab heev thiab tsim los xyuas cov feeb hydrogen leaks. Before personnel enter the battery room for operation, maintenance, or inspection, they remind operation and maintenance staff to detect leaks early, conduct preventive maintenance to locate the leak, and more accurately pinpoint the source of minor leaks. Tom qab pib qhov cua, lub tshuab nqus tsev H2 portable yog siv los xyuas kom meej tias cov concentration puas tau txo qis.
0-100% LEL feem ntau yog siv rau hauv cov khoom siv hluav taws xob ruaj khov, nrog lub tswb nrov teeb tsa ntawm 25% LEL thiab lub tswb thib ob tau teeb tsa ntawm 50% LEL. Qhov no tso cai rau qhov cua los yog kev sib txuas tswj tau pib ua ntej muaj teeb meem tshwm sim, uas yog ib yam dab tsi uas PPM ntes tsis tuaj yeem ua tiav. Tsau hydrogen detectors tuaj yeem txuas ntxiv thiab cia li saib xyuas cov hydrogen concentration ntawm cov chaw tseem ceeb hauv chav roj teeb (tshwj xeeb tshaj yog nyob rau lub ru tsev, hauv cov ces kaum, saum cov roj teeb pob, thiab hauv qhov cua qhov chaw tuag) 24 teev hauv ib hnub, ua haujlwm tseem ceeb ntawm kev tiv thaiv kev nyab xeeb. 0-100% LEL ntau yam yog tsim los tiv thaiv kev tawg los ntawm kev muaj siab, thiab yuav tsum muaj nyob hauv chav roj teeb. Lub Fixed h2 detector muab kev ceeb toom ua ntej qhov concentration nce mus txog theem txaus ntshai, ua rau cov neeg ua haujlwm ntsuas (xws li pib ua cua txias thiab khiav tawm cov neeg ua haujlwm).
