Shenhai Explosion-Proof
Wb pib los piav cov tawg tawg-pov thawj kev ntsuam xyuas, lawv kos npe rau daim ntawv qhia txog kev kos npe, thiab xaiv seb lawv xyaum li cas, Siv explosion-proof tis thawv ua ib qho piv txwv.
| Roj/kub pab pawg neeg/kub pab pawg neeg | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, acrylic acid, benzene, styrene, pa roj carbon monoxide, ethyl acetate, qaub, chlorobenzene, methyl acetate, tshuaj chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, tiam sis taum, tiam sis acetate, amyl acetate, cyclopentane | hnub, cwj mem qhuav, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, ntawv so ntswg, roj av (roj av), roj, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | hydrogen, roj | Acetylene | Carbon disulfide | Ethyl nitrate |
Certification marking:
Ex d IIB T4 Gb/Ex tD A21 IP65 T130°C yog ib universal daim ntawv pov thawj rau roj thiab plua plav tawg, Qhov twg qhov twg ua ntej lub slash (/) indicates cov roj tawg-pov thawj theem, Thiab qhov tom qab lub slash indicates plua plav tawg-pov thawj.
Ex: Tawg-pov thawj marking, hom ntawv ntawm IEC (Tseev tsim ntiaj teb Electrotechnical Commission) tawg-profo ntsuam xyuas.
d: taws Yam, Indicating tus thawj daim ntawv ntawm tawg tiv thaiv yog flameproof.
IIB: Nruab nrab yog hoob kawm B roj tawg tiv thaiv.
T4: Qhia txog qhov txias hoob kawm.
gb: Qhia qhov khoom no yog suitable rau Zone 1 tawg.
Rau qhov plua plav tawg ib sab ntawm lub tom kawg ib nrab hnub, Nws yog txaus mus cuag cov plua plav ntau tshaj plaws 6 Raws li cov roj tawg-pov thawj qauv.
tD: Nruab nrab yog hom enclosure tiv thaiv (tiv thaiv kom tsis txhob muaj plua plav ignition nrog enclosure).
A21: Qhia txog qhov cheeb tsam uas muaj feem xyuam rau txoj kev kawm ntawv, suitable rau Zone 21, tsam 22.
IP65: Nruab nrab yog cov qib kawm.
Nws tseem ceeb heev uas yuav xaiv cov tawg tawg-pov thawj ntsuam xyuas nyob rau hauv tej cheeb tsam.
Thawj, Nws tseem ceeb heev uas yuav tau to taub ob lub ntsiab pawg, raws li tau piav nyob rau hauv qab no:
Tawg-profo:
Hoob Kawm Kuv: Hluav taws xob khoom rau underground thee mines;
Hoob Kawm II: Hluav Taws Xob Khoom Siv Rau Tag Nrho Lwm Yam explosive Roj tej chaw tsuas yog thee mines thiab underground.
Hoob kawm II yuav muab faib ua IIA, IIB, thiab IIC, Qhov twg cov khoom cim IIB yuav siv tau raws li tej yam mob suitable rau IIA li; IIC yuav siv tau raws li tej yam mob suitable rau ob IIA thiab IIB.
Hoob Kawm III: Hluav taws xob khoom rau explosive tej chaw uas tsis yog thee mines.
IIIA: Combustible ya; IIIB: Plua plav uas tsis yog plua plav; IIIC: Tsim kom muaj plua plav.
Explosion-proof chaw:
tsam 0: Qhov twg explosive gases yeej ib txwm los yog feem ntau tam sim no; continuously hazardous rau ntau tshaj 1000 teev/xyoo;
tsam 1: Uas qhov khuv gases yuav tshwm sim thaum lub lag luam; intermittently hazardous rau 10 mus rau 1000 teev/xyoo;
tsam 2: Qhov twg flammable gases yuav tsis nquag tam sim no thiab, tshwm sim, tej zaum yuav infrequent thiab short-lived; tsis zoo rau koj 0.1 mus rau 10 teev/xyoo.
Nws tseem ceeb heev uas peb deal nrog hoob kawm II thiab III, tsam 1, tsam 2; tsam 21, tsam 22.
feem ntau, xeeb IIB txaus rau gases, tab sis rau hydrogen, acetylene, thiab carbon disulfide, Ib theem siab dua ntawm IIC yuav tsum tau txhaj. Rau plua plav tawg, cia li cuag lub corresponding roj tawg-profo thiab qib siab tshaj plaws.
Kuj yog ib hom combined hom tawg-proof tis kev ntsuam xyuas: ExdeIIBT4Gb.
