Isho ukuthini I-Explosion-Proof Level Exd II BT4

Imikhiqizo engaqhumi ngayinye inesilinganiso sokuvikela ukuqhuma, ehlukanisa uhlobo lomkhiqizo lomklamo ongaqhumi kanye nezimo ezisebenzayo. Ngokwesibonelo, isilinganiso sokuvikela ukuqhuma Exd IIB T4 sichazwe ngokuningiliziwe ngezansi.

Ex: Uphawu olungaqhumi.

d: Uhlobo lokuvikela ukuqhuma angashi. Kukhona futhi izinhlobo zokuphepha zangaphakathi ia, ib; ukwanda kokuphepha uhlobo e; uhlobo olugcwele amafutha o; uhlobo olugcwele isihlabathi q; uhlobo oluhlanganisiwe m; kanye nohlobo oluyinhlanganisela (evame ukusetshenziswa emabhokisini okusabalalisa angaqhumi).

II: Kubhekiselwa esigabeni sesibili se izinto zikagesi ezingaqhumi. Lesi sigaba sifanelekile eziqhumayo izindawo zegesi ngaphandle kwezimayini zamalahle (Ikilasi I). Kukhona futhi i-Class III: Izinto zikagesi zezindawo zothuli oluqhumayo ngaphandle kwezimayini zamalahle. Ikilasi IIIA: Imicu evuthayo; Isigaba IIIB: Uthuli olungaqhubeki; Ikilasi III: Uthuli lwe-conductive.

B: Igesi ye-Class IIB. Kukhona futhi i-IIC ne-IIA. Inani eliphakeme kakhulu lama-IIC, kusebenza ku-IIA naku-IIB. I-IIB ifanele i-IIA, kodwa amazinga aphansi awakwazi ukusebenzisa aphezulu.

T4: I izinga lokushisa ikilasi T4, nezinga lokushisa eliphezulu lemishini elingaphansi kuka-135°C.
