Shenhai Kuphulika-Umboni
Tiyeni tiyambe ndi kufotokoza mavoti osiyanasiyana osaphulika, zomwe zikutanthawuza, ndi momwe mungawasankhire pochita, pogwiritsa ntchito mabokosi ogawa osaphulika monga chitsanzo.
| Gulu la gasi / gulu la kutentha | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, acrylic asidi, benzene, styrene, carbon monoxide, ethyl acetate, asidi asidi, chlorobenzene, methyl acetate, klorini | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, naphtha, mafuta (kuphatikizapo mafuta), mafuta amafuta, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | haidrojeni, gasi wamadzi | Acetylene | Mpweya wa carbon disulfide | Ethyl nitrate |
Chizindikiro cha satifiketi:
Ex d IIB T4 Gb/Ex tD A21 IP65 T130°C ndi chiphaso chapadziko lonse choteteza kuphulika kwa mpweya ndi fumbi., pomwe gawo lisanasewere (/) zimasonyeza mlingo wa gasi wosaphulika, ndipo gawo pambuyo pa slash likuwonetsa kuti fumbi silingaphulike.
Eks: Chizindikiro chosaphulika, mtundu wokhazikika wa IEC (International Electrotechnical Commission) mavoti osaphulika.
d: Zosayaka moto mtundu, kusonyeza mtundu woyamba wa chitetezo kuphulika ndi kupsa.
IIB: Zimayimira chitetezo cha kuphulika kwa mpweya wa Gulu B.
T4: Imawonetsa kutentha kalasi.
Gb: Zikuwonetsa kuti mankhwalawa ndi oyenera Zone 1 chitetezo kuphulika.
Za ku kuphulika kwafumbi gawo mu theka lomaliza, ndizokwanira kukwaniritsa kalasi yapamwamba kwambiri yoteteza fumbi 6 kutengera miyezo yotsimikizira kuphulika kwa gasi.
tD: Zimayimira mtundu wa chitetezo champanda (kuteteza fumbi kuyaka ndi mpanda).
A21: Imawonetsa malo oyenerera, zoyenera Zone 21, Zone 22.
IP65: Imayimira gawo lachitetezo.
Ndikofunikira kusankha mavoti olondola osaphulika m'malo enieni.
Choyamba, ndikofunikira kumvetsetsa magulu awiri akulu, monga tafotokozera pansipa:
Mitundu yosaphulika:
Kalasi I: Zida zamagetsi zopangira migodi ya malasha yapansi panthaka;
Kalasi II: Zida zamagetsi zina zonse zophulika malo a gasi kupatulapo migodi ya malasha ndi yapansi panthaka.
Kalasi II ikhoza kugawidwa mu IIA, IIB, ndi IIC, kumene zida zolembedwa IIB zitha kugwiritsidwa ntchito pansi pazikhalidwe zoyenera zida za IIA; IIC itha kugwiritsidwa ntchito pamikhalidwe yoyenera IIA ndi IIB.
Kalasi III: Zida zamagetsi zopangira fumbi lophulika kupatula migodi ya malasha.
IIIA: Ndege zoyaka; IIIB: Non-conductive fumbi; IIIC: Fumbi la conductive.
Malo osaphulika:
Zone 0: Kumene mpweya wophulika umakhalapo nthawi zonse kapena kawirikawiri; zowopsa mosalekeza kuposa 1000 maola/chaka;
Zone 1: Kuti kuyaka mpweya ukhoza kuchitika panthawi yogwira ntchito bwino; zowopsa pafupipafupi 10 ku 1000 maola/chaka;
Zone 2: Kumene mipweya yoyaka moto siipezeka kawirikawiri ndipo, ngati zichitika, atha kukhala osawerengeka komanso osakhalitsa; zowopsa kupezeka kwa 0.1 ku 10 maola/chaka.
Ndikofunika kuzindikira kuti timachita ndi Gulu la II ndi III, Zone 1, Zone 2; Zone 21, Zone 22.
Nthawi zambiri, kufika ku IIB ndikokwanira kwa mpweya, koma kwa haidrojeni, acetylene, ndi carbon disulfide, mlingo wapamwamba wa IIC ukufunika. Kwa chitetezo cha fumbi kuphulika, kungokwaniritsa gasi lolingana mulingo wosaphulika ndi fumbi lapamwamba kwambiri.
Palinso mtundu wophatikizidwa wa bokosi logawa losaphulika mlingo: ExdeIIBT4Gb.
