Flameproof explosion-proof khoom siv hluav taws xob encapsulates cov khoom uas tuaj yeem tsim cov nplaim taws, arcs, thiab qhov kub thiab txias tsis zoo nyob rau hauv qhov chaw tawg-pov thawj. Qhov kev kaw no tswj qhov tawg sab hauv, tiv thaiv nws los ntawm igniting flammable gases thiab hmoov av. Cov nplaim hluav taws kub hnyiab yuav tsum muaj lub zog siv hluav taws xob txaus los tiv thaiv kev tawg hauv qhov tsis muaj kev puas tsuaj. Qhov sib txawv tawg yog tsim los kom cov nplaim taws txias, qeeb nplaim taws kev nthuav tawm, thiab cuam tshuam lub acceleration saw, tiv thaiv sab nraud ignition nyob rau hauv explosive ib puag ncig.
Ntau hom kev nyab xeeb
Cov khoom siv hluav taws xob tawg ua kom muaj kev nyab xeeb ntxiv tsom rau kev txhim kho cov hluav taws xob sab hauv kev nyab xeeb los ntawm kev siv tshuab, hluav taws xob, thiab thermal tiv thaiv ntsuas los tiv thaiv ignition hauv combustible gas ib puag ncig. Cov ntaub ntawv qib siab rwb thaiv tsev yog siv los txo kev sib cuag, yog li ntawd txo qhov kub thiab txias. Kev tiv thaiv qib siab yog siab (tsis tsawg dua IP54). Feem ntau, hom no suav nrog cov xaim hluav taws xob thiab cov khoom siv hluav taws xob tab sis tsis nruab cov thawv tawg-pov thawj, tam sim no transformers, lossis lwm yam khoom siv hluav taws xob.
Intrinsic Safety Hom
Ua kom tiav cov hom phiaj tawg-pov thawj, yam kev nyab xeeb yam siv zog txwv hauv circuits. Kev ntsuas hluav taws xob, xws li voltage, tam sim no, inductance, thiab capacitance, yuav tsum ua tau raws li qhov yuav tsum tau ua kom tawg. Txawm nyob rau hauv cov xwm txheej luv luv, rwb thaiv tsev tawg, los yog lwm yam txhaum uas ua rau hluav taws xob tawm thiab thermal cuam tshuam, nws yuav tsis ignite ib tawg gas cua. Cov txheej txheem no poob rau hauv 'tsis muaj zog’ technology qeb, qhia txog kev txwv hluav taws xob thiab thermal zog nrog lub zog tso zis tsawg. Cov cuab yeej tsis muaj peev xwm tsim tau tej yam uas yuav ua rau muaj kev phom sij.
