Shenhai Explosion-Proof
Cov cuab yeej siv hluav taws xob muaj kev ruaj ntseg yuav tsum tau muab tso rau hauv ib lub thawv tsim kom zoo. Cov casing no yog qhov tseem ceeb tsis yog rau kev sib sau cov khoom siv hluav taws xob nkaus xwb tab sis kuj tseem tiv thaiv lawv los ntawm kev hem sab nraud xws li cov khoom siv., ya raws, thiab dej. Cov ntsiab lus no ua rau muaj kev pheej hmoo loj heev vim lawv tuaj yeem ua rau luv luv, rwb thaiv tsev tawg, thiab tej zaum yuav muaj teeb meem hluav taws xob tawm.
Nws paub zoo tias cov khoom siv hluav taws xob muaj kev cuam tshuam rau ib puag ncig yam. Cov khoom tsis huv, piv txwv, tuaj yeem nkag mus thiab ua rau luv luv, thaum ya raws tuaj yeem degrade rwb thaiv tsev, ua rau xau thiab sparks - qhov xwm txheej txaus ntshai tiag tiag. Kev siv cov ntaub thaiv npog nrog kev tiv thaiv tsim nyog tuaj yeem tiv thaiv cov kev pheej hmoo no.
Raws li tus qauv GB4208-2008, uas qhia txog qib kev tiv thaiv enclosure (IP cov lej), cov qib no tau sawv cev los ntawm IP code ua raws li ob tus lej thiab qee zaum sau ntawv ntxiv. Thawj tus lej qhia txog qib ntawm kev tiv thaiv cov khoom siv, thiab qhov thib ob tiv thaiv dej. Piv txwv li, ib qho chaw nyob IP54 muaj qee qhov kev tiv thaiv tiv thaiv cov khib nyiab thiab kua. GB4208-2008 categorizes tiv thaiv cov khib nyiab rau hauv 6 theem thiab tiv thaiv dej rau hauv 8 qib.
Thaum nws los txog rau enclosures:
Nrog nthuav tawm nyob qhov chaw, Yam tsawg kawg ntawm IP54 yog yuav tsum tau.
Nrog insulated nyob qhov chaw hauv, nws kuj yuav tsum yog tsawg kawg yog IP54.

Rau qhov cua:
Hauv chav kawm I khoom siv, yam tsawg kawg nkaus IP54 (rau qhov tsis muaj teeb-emitting nyob qhov chaw) los yog IP44 (rau insulated nyob qhov chaw) yog yuav tsum tau.
Rau cov khoom siv Class II, Qhov ntsuas yuav tsum tsis txhob tsawg dua IP44, tsis hais hom ntawm cov khoom siv sab hauv.
Yog tias cov khoom siv hluav taws xob muaj kev ruaj ntseg zoo dua muaj intrinsically nyab xeeb circuits los yog systems, cov no yuav tsum tau sib cais los ntawm cov tsis muaj kev nyab xeeb hauv lub cev. Cov kab hluav taws xob tsis muaj kev nyab xeeb yuav tsum tau nyob hauv ib chav nrog tsawg kawg yog IP30 ntsuas, cim nrog ceeb toom: “Tsis txhob qhib thaum muaj hluav taws xob!”
Lub kaw lus ntawm kev txhim kho-kev nyab xeeb khoom siv hluav taws xob yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv sab hauv los ntawm kev cuam tshuam sab nraud thiab ua kom cov rwb thaiv tsev ua haujlwm ntawm cov hluav taws xob tsis zoo., li no lub sij hawm “txhim khu kev ruaj ntseg enclosure.”
