Shenhai Kuputika-Uchapupu
The Equipment Dziviriro Level (EPL) inoongorora kuvimbika-kupupudza kuvimbika kweimwe mhando yechishandiso zvichibva pane zvinogona kukanganisa uye matanho ekudzivirira., kushanda sechinhu chakakosha chekuchengetedza chiratidzo chekuputika-chisina kuputika magetsi emidziyo.
| Condition Category | Gasi Classification | Anomiririra magasi | Minimum Ignition Spark Energy |
|---|---|---|---|
| Under The Mine | I | Methane | 0.280mJ |
| Mafekitori Kunze Kwemugodhi | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | Hydrogen | 0.019mJ |
Iwo mazinga akaiswa muzvikamu sea, b, uye c:
1. Level a inovimbisa kuputika-chiratidziro chekuchengetedza kuchengetedza kushanda pasi pemaitiro akajairwa uye panguva dzese dzinofungidzirwa uye dzisingawanzo kukanganisa..
2. Level b inovimbisa kuchengetwa kwekuputika-uchapupu hwekuchengetedza mashandiro panguva yenguva dzose mashandiro uye zvikanganiso zvinoonekwa..
3. Level c inovimbisa kuchengetedzwa kwekuputika-proof kuchengetedza kuita mune ese akajairwa mashandiro uye chaiwo mamiriro asina kujairika..
Kazhinji, mudziyo unoputika unotarisirwa kusangana neNhamba 3 kudzivirira. Mune zvimwe zviitiko, zvisinei, Levels 2 kana 1 inogona kutenderwa kune dzakanangana-dzinoputika mhando.
Kumaka nzira dzinosanganisira:
1. Kubva pachiratidzo chemhando yekuputika:
Kusanganiswa kwe kuputika-uchapupu mhando uye zvidziviriro zvechidziviriro nhanho zviratidzo zvinoreva nhanho yekudzivirira. Semuyenzaniso, midziyo yekuchengetedza inocherechedzwa kuti ia, ib, kana ic.
2. Zvichienderana nemhando yemidziyo chiratidzo:
Kubatanidza mhando yemidziyo uye zviratidzo zvezinga rekudzivirira kunoratidza mwero wekudzivirira. Semuyenzaniso, Kirasi I (kuchera) mudziyo wakanyorwa seMa kana Mb (M vachimiririra wangu); Kirasi III (fekitari, gasi) midziyo yakanyorwa seGa, Gb, kana Ge (G yegesi).
Izvo zvakakosha kuti unzwisise kuti mazinga ekudzivirira emidziyo uye kuputika-chiratidzo mazinga ndiwo akasiyana pfungwa anowanzo kuvhiringidzika mukushandisa.. Chiyero chekudzivirira chinoratidza “kuvimbika,” nepo kuputika-kwezinga rinoratidza “gasi rinobvira zvivakwa uye midziyo yemaitiro maficha.” Semuyenzaniso, munzvimbo yeindasitiri ine njodzi yekuputika kwehydrogen (Zone 0), zvinodiwa mukati mekuchengetedza midziyo ingave Level ia, Kuputika-Chiratidzo Chikamu IIC. Mune zvishoma kazhinji hydrogen kuisa njodzi (Zone 1), Level ib, IIC yemukati yekuchengetedza michina yaizozadzisa zvinodiwa, kunyangwe Level ia, IIC michina inogonawo kuve yakakodzera.
