Shenhai Explosion-Proof
Me timata ma te whakamaarama i nga momo whakatauranga pahū, he aha ta ratou e tohu nei, me pehea te whiriwhiri i a raatau mahi, te whakamahi i nga pouaka toha pahū-pahū hei tauira.
| Rōpū hau/rōpū pāmahana | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl hākawa, acetylene, propane, acetone, waikawa kiriaku, te pene, styrene, waro haukura, ethyl acetate, waikawa ahetiki, pūhāhā, methyl acetate, māota | Mewaro, waiwaro, ethylbenzene, propanol, propylene, pūtānora, butyl acetate, amyl acetate, cyclopentane | Penetane, pentanol, hexane, waiwaro, hepetane, octane, cyclohexanol, turpentine, napata, hinuhinu (tae atu ki te penehīni), hinu hinu, tetrachloride pentanol | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hauwai carbide | |||
| IIC | hauwai, hau wai | Aetilena | Te waro disulfide | Ethyl pākawa |
Te tohu tohu:
Ex d IIB T4 Gb/Ex tD A21 IP65 T130°C he tiwhikete mo te katoa mo te whakamarumaru hau me te puehu pahū, kei hea te wahanga i mua i te rītaha (/) e tohu ana i te taumata pahū hau, a ko te wahanga i muri i te riitaha he tohu pahū-puehu.
Ex: Te tohu pahū, te whakatakotoranga paerewa o IEC (Te Komihana Hiko o te Ao) whakawākanga pahū.
d: Parenga mura momo, e tohu ana ko te ahua tuatahi o te whakamarutanga pahū he mura.
IIB: He tohu mo te whakamarumaru hau pahū o te akomanga B.
T4: Ka tohu i te pāmahana akomanga.
Gb: E tohu ana he pai tenei hua mo te Rohe 1 parenga pahū.
Mo nga pahū puehu wahi i te haurua whakamutunga, he rawaka ki te whakatutuki i te taumata teitei o te tiaki puehu 6 i runga i nga paerewa pahū hau.
tD: He tohu mo te momo whakamarumaru whakamarumaru (te aukati i te mura o te puehu me te kati).
A21: Ka tohu i te waahi e tika ana, e tika ana mo te Rohe 21, Rohe 22.
IP65: E tohu ana i te karaehe whakamarumaru.
He mea nui ki te kowhiri i te whakatauranga pahū-whakatika tika i roto i nga taiao.
Tuatahi, he mea nui kia mohio ki nga waahanga matua e rua, i whakaahuatia i raro nei:
Nga momo pahū:
Te akomanga I: Nga taputapu hiko mo nga keri waro i raro i te whenua;
Class II: Nga taputapu hiko mo era atu katoa pahū taiao hau haunga maina waro me raro.
Ka taea te wehea te akomanga II ki te IIA, IIB, me te IIC, ka taea te whakamahi i nga taputapu kua tohua IIB i raro i nga tikanga e tika ana mo nga taputapu IIA; Ka taea te whakamahi IIC i raro i nga tikanga e tika ana mo te IIA me te IIB.
Class III: Nga taputapu hiko mo nga taiao puehu pahū atu i nga maina waro.
IIIA: Nga rere mura; IIIB: Te puehu kore-conductive; IIIC: Te puehu whakaheke.
Nga waahi pahū:
Rohe 0: I nga wa katoa, he maha ranei nga hau pahū; morearea tonu mo neke atu i te 1000 haora/tau;
Rohe 1: Kei hea muramura ka puta pea nga hau i te wa e mahi noa ana; he morearea mo 10 ki 1000 haora/tau;
Rohe 2: I te nuinga o te waa karekau he karehu muramura, mehemea ka puta, he iti noa, he poto te wa; kei te noho morearea mo 0.1 ki 10 haora/tau.
He mea nui kia mohio kei te mahi tatou ki te Class II me III, Rohe 1, Rohe 2; Rohe 21, Rohe 22.
Tikanga, ka eke ki te IIB he rawaka mo nga hau, engari mo hauwai, acetylene, me te waro disulfide, he taumata teitei ake o te IIC e hiahiatia ana. Mo te whakamarumaru pahū puehu, tutuki noa te hau e rite ana taumata pahū me te taumata teitei o te puehu.
He momo whakakotahi ano pouaka tohatoha pahū whakatauranga: ExdeIIBT4Gb.
