Shenhai Explosion-Proof
Muaj coob tus neeg muas zaub feem ntau nug txog cov parameters ntawm kev tiv thaiv thiab tawg-pov thawj theem thaum muas explosion-proof khoom. tiam sis, Cov nam tseem ceeb heev yog feem ntau overlooked, Ua rau ntau tsis meej pem ntawm ob concepts. Hnub no, Wb hais qhov txawv ntawm txoj kev tiv thaiv thiab tawg-pov thawj theem:
Tawg-Proof: Lub sij hawm no hais txog cov hoob kawm uas hluav taws xob siv nyob rau tej cheeb tsam hazardous.
kev tiv thaiv: Relates dej thiab plua plav kuj.
Tawg-Profo:
Piv txwv, tawg-pov thawj cim “Ex (tub sab) IIC T6” signifies:
| Cov Ntsiab Lus Qhia Txog Kev Kawm | Cim | qab hau |
|---|---|---|
| Tawg pov thawj tshaj tawm | Ex | Raws li tej tawg-pov thawj kawm, Xws li lub teb chaws Suav lub teb chaws qauv |
| Tawg pov thawj | tub sab | Adopting IA theem intrinsic kev ruaj ntseg explosion-proof txoj kev, Nws yuav muab ntsia hauv Zone 0 |
| Roj qeb | IIC | Tau cog lus rau IIC explosive gases |
| txias | T6 | Qhov chaw kub txog qhov kub tshaj plaws yuav tsum tsis txhob tshaj 85 °C |
Kev Tiv Thaiv:
Rau cov lus qhia siv nyob rau hauv explosive ua kom muaj kev puas siab puas nkeeg, Nws tseem ceeb heev uas yuav tau hais kom tiv thaiv theem ntawm lawv enclosures. Qhov no yog uas muaj tuaj los ntawm cov IP ntsuam xyuas.
Thawj theem ntawm kev tiv thaiv tib neeg nyob thiab mus qhov chaw hauv lub enclosure, Thiab raws li cov ingress ntawm khoom solid khoom.
Qhov thib ob ntawm kev tiv thaiv tiv thaiv kev tiv thaiv teebmeem los ntawm dej nkag mus rau hauv cov khoom.
Thawj tus digit tom qab “IP” qhia txog cov plua plav uas tsis muaj plua plav.
| Naj npawb | Kev tiv thaiv ntau yam | Piav |
|---|---|---|
| 0 | Unprotected | Tsis muaj kev tiv thaiv tshwj xeeb rau lwm tus neeg los yog khoom |
| 1 | Tiv thaiv tau cov khoom txawv teb chaws uas muaj ib diameter ntau tshaj 50mm los mus hauv | Tiv thaiv kom tib neeg lub cev (xws li lub xibtes) Los ntawm kev ntawd los mus cuag nrog hluav taws xob hluav taws xob components, thiab tiv thaiv lwm yam khoom (Nrog ib diameter ntau dua 50m) nkag mus rau hauv |
| 2 | Tiv thaiv tau cov khoom txawv teb chaws uas muaj ib diameter ntau dua 12.5mm ntawm nkag mus rau hauv | Tiv thaiv tib neeg ntiv tes los kov qhov chaw hauv hluav taws xob thiab tiv thaiv nruab nrab sized (diameter ntau dua 12.5m) txawv teb chaws khoom los nkag mus rau hauv |
| 3 | Tiv thaiv tau cov khoom txawv teb chaws uas muaj ib diameter ntau dua 2.5mm los mus hauv | Tiv thaiv cov cuab yeej, hlau, thiab zoo sib xws me me uas muaj ib diameter los yog thickness ntau dua 2.5mm ntawm invading thiab los mus cuag qhov chaw hauv hluav taws xob |
| 4 | Tiv thaiv tau cov khoom txawv teb chaws uas muaj ib diameter ntau dua 1.0mm los nkag mus rau hauv | Tiv thaiv cov cuab yeej, hlau, thiab zoo sib xws me me uas muaj ib diameter los yog thickness ntau dua 1.0m ntawm invading thiab los mus cuag qhov chaw hauv hluav taws xob |
| 5 | Tiv thaiv lwm yam khoom thiab plua plav | Kiag li tiv thaiv txawv teb chaws khoom los nkag mus rau hauv, Txawm hais tias nws yuav tiv thaiv tsis tau plua plav los ntawm kev nkag mus rau hauv, Qhov tsis zoo ntawm cov plua plav yuav tsis muaj feem xyuam rau txoj kev zov me nyuam ntawm cov khoom siv fais fab tuag |
| 6 | Tiv thaiv lwm yam khoom thiab plua plav | Kiag li tiv thaiv cov intrusion ntawm txawv teb chaws khoom thiab plua plav |
Tus thib ob digit signifies theem ntawm dej tiv thaiv.
| Naj npawb | Kev tiv thaiv ntau yam | Piav |
|---|---|---|
| 0 | Unprotected | Tsis muaj kev tiv thaiv tshwj xeeb tiv thaiv dej los yog moisture |
| 1 | Tiv thaiv kom txhob muaj dej los ntawm soaking hauv soaking nyob rau hauv | Vertically ntog dej droplets (xws li condensate) yuav tsis ua kom muaj kev puas tsuaj rau hluav taws xob |
| 2 | Thaum tilted ntawm 15 degrees, Cov dej xab nkaus tseem yuav tiv thaiv tau kom txhob soaking nyob rau hauv | Thaum lub appliance yog tilted vertically rau 15 degrees, dripping dej yuav tsis ua rau kom muaj kev puas tsuaj rau lub appliance |
| 3 | Tiv thaiv kom txhob raug dej los ntawm soaking hauv | Tiv thaiv kom tsis txhob muaj hluav taws xob los yog puas hluav taws xob los ntawm dej sprayed nyob rau hauv cov lus qhia uas muaj ib lub kaum sab xis ntawm tsawg tshaj li 60 degrees |
| 4 | Tiv thaiv splashing dej los nkag mus rau hauv | Tiv thaiv dej splashing los ntawm tag nrho cov lus qhia los ntawm kev nkag mus rau hauv hluav taws xob thiab ua rau puas tsuaj |
