Ibtawg- pov thawj lub cev muaj zogyog hom lub cev muaj zog uas tuaj yeem siv rau hauv qhov chaw tawg thiab tawg thiab tsis tsim hluav taws xob hluav taws xob thaum ua haujlwm. Lawv tsuas yog siv nyob rau hauv cov mines, roj thiab natural gas, petrochemical thiab tshuaj industries. Tsis tas li ntawd, lawv kuj tau siv dav hauv textile, metallurgy, nroog gas, tsheb thauj mus los, nplej thiab roj ua, papermaking, tshuaj thiab lwm yam haujlwm. Raws li cov khoom siv hluav taws xob tseem ceeb, kev tawg-cov pov thawj motors feem ntau yog siv los tsav cov twj, kiv cua, compressors thiab lwm yam khoom siv sib kis. Nws yog lub cev muaj zog tsim tshwj xeeb nrog kev tawg- pov thawj kev ua tau zoo, uas tuaj yeem ua haujlwm nyab xeeb hauv qhov chaw tawg thiab tawg.
Ces yog vim li cas thiaj ua tautawg-cov pov thawj motorspuas yog tawg- pov thawj? Nyob rau hauv lub xub ntiag ntawm huab cua, flammable gases, combustible plua plav, vapors los yog fibers muab roj thiab oxidants rau combustion los yog tawg, tab sis ib tug ignition qhov chaw yog tseem yuav tsum tau ignite cov tshuaj tiv thaiv los tsim ib tug explosive cua. Hom ignition muaj xws li: sparks los yog arcs generated los ntawm cov khoom siv hluav taws xob los yog nyob ntawm tej, qhib nplaim taws (vuam), tshuaj lom neeg los yog tshuaj lom neeg, qib oxygen los yog kub, xob laim, ionizing hluav taws xob, compression tsis thiab poob siab, thiab hluav taws xob zoo li qub.
Qhov laj thawj yog vim li cas lawv tawg - pov thawj tsis yog tias lawv tuaj yeem tiv thaiv lwm yam xwm txheej tawg, tab sis rau lub cev muaj zog nws tus kheej, kev ntsuas tsim nyog tuaj yeem tiv thaiv qhov xwm txheej tawg los ntawm teeb meem nrog lub cev muaj zog. Piv txwv li, thaum muaj teeb meem hluav taws xob tshwm sim nyob rau hauv lub cev muaj zog windings, lub txim tshwm sim yuav raug kaw nyob rau hauv lub cev muaj zog kab noj hniav, tiv thaiv tej teeb meem tawg sab nraum lub cev muaj zog nws tus kheej.
Los ntawm qhov kev xav ntawm lub hauv paus ntsiab lus tsim, lub tswv yim yooj yim yog siv lub zog ntawm cov yam ntxwv uas yuav ua rau tawg los ntawm kev tiv thaiv kom txaus, nrog rau qhov ntev haum thiab txaus me me qhov sib txawv ntawm cov khoom. Thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, cov casing lossis cov khoom sib txuas ncaj qha nrog rau ib puag ncig sab nraud yuav tsis tsim cov txim taws lossis lwm yam teebmeem uas yuav ua rau tawg vim lawv txoj haujlwm. Yog li ntawd, muaj cov kev cai tshwj xeeb ntawm cov khoom ntawm cov khoom tawg - pov thawj motors.
