Shenhai Kuputika-Uchapupu
Ngatitangei nekutsanangura zvakasiyana-siyana kuputika-proof ratings, zvavanoreva, uye kuti ungazvisarudza sei mukuita, kushandisa mabhokisi ekuparadzira-anoputika semuenzaniso.
| Boka regesi/tembiricha boka | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, acrylic asidhi, benzene, styrene, carbon monoxide, ethyl acetate, acetic acid, chlorobenzene, methyl acetate, chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, naphtha, peturu (kusanganisira peturu), mafuta emafuta, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | Hydrogen, gasi remvura | Acetylene | Carbon disulfide | Ethyl nitrate |
Certification marking:
Ex d IIB T4 Gb/Ex tD A21 IP65 T130°C chitupa chepasi rose chekudzivirira gasi uye kuputika kweguruva., apo chikamu chisati chatemwa (/) inoratidza gasi-rinodzivirira gasi, uye chikamu mushure mekucheka chinoratidza guruva rinoputika-uchapupu.
Ex: kuputika-kumira chiratidzo, iyo yakajairika fomati yeIEC (International Electrotechnical Commission) kuputika-proof ratings.
d: Flameproof type, zvichiratidza nzira yekutanga yekudzivirira kuputika isingapfute.
IIB: Inomiririra Kirasi B gasi kudzivirira kuputika.
T4: Inoratidza the tembiricha class.
Gb: Inoratidza kuti chigadzirwa ichi chakakodzera Zone 1 kudzivirira kuputika.
For the kuputika kweguruva chikamu muhafu yekupedzisira, zvakakwana kuti uwane yepamusoro-soro yekudzivirira guruva giredhi 6 zvichibva pane gasi kuputika-uchapupu zviyero.
tD: Inomiririra rudzi rwekuchengetedzwa kwemukati (kudzivirira guruva kubatidzwa neyakavharirwa).
A21: Inoratidza nzvimbo inoshanda, yakakodzera Zone 21, Zone 22.
IP65: Inomiririra giredhi rekudzivirira.
Izvo zvakakosha kuti usarudze iyo chaiyo yekuputika-chiratidzo chiyero munzvimbo chaidzo.
Chekutanga, zvakakosha kunzwisisa mapoka makuru maviri, sezvinotsanangurwa pasi apa:
Mhando dzekuputika-dziviriro:
Kirasi I: Midziyo yemagetsi kumigodhi yemarasha pasi pevhu;
Kirasi II: Midziyo yemagetsi kune zvimwe zvese zvinoputika gasi nharaunda kunze kwemigodhi yemarasha nepasi pevhu.
Kirasi II inogona kukamurwa kuita IIA, IIB, uye IIC, uko michina yakanyorwa IIB inogona kushandiswa pasi pemamiriro akakodzera IIA zvishandiso; IIC inogona kushandiswa pasi pemamiriro akakodzera kune ese IIA neIIB.
Kirasi III: Midziyo yemagetsi yenzvimbo dzinoputika huruva kunze kwemigodhi yemarasha.
IIIA: Kubhururuka kwendege; IIIB: Non-conductive guruva; IIIC: Conductive guruva.
Nzvimbo dzisina kuputika:
Zone 0: Ipo magasi anoputika anogara aripo kana kuti kazhinji aripo; zvinoramba zvichikuvadza kupfuura 1000 maawa/gore;
Zone 1: Kupi zvinobvira moto magasi anogona kuitika panguva yakajairika kushanda; nguva nenguva ngozi kune 10 ku 1000 maawa/gore;
Zone 2: Apo magasi anopisa haawanzovapo uye, kana zvikaitika, zvinogona kunge zvisingawanzoitiki uye zvenguva pfupi; zvine njodzi iripo ye 0.1 ku 10 maawa/gore.
Zvakakosha kuziva kuti tinobata neClass II uye III, Zone 1, Zone 2; Zone 21, Zone 22.
Kazhinji, kusvika kuIIB zvakakwana kune magasi, asi nokuda hydrogen, acetylene, uye carbon disulfide, chiyero chepamusoro cheIIC chinodiwa. Nokuda kwekudzivirira kuputika kweguruva, ingozadzisa gasi rinoenderana kuputika-chiratidzo chezinga uye yepamusoro-soro guruva giredhi.
Kune zvakare mhando yakasanganiswa ye bhokisi rekupaza rinoputika rating: ExdeIIBT4Gb.
