Shenhai Explosion-Proof
Cov khoom tawg-pov thawj txhua tus muaj qhov ntsuas tawg-pov thawj, uas paub qhov txawv ntawm cov khoom ntawm cov khoom tawg-pov thawj tsim thiab siv cov xwm txheej. Piv txwv li, Qhov kev ntsuas tawg-pov thawj Exd IIB T4 tau piav qhia hauv qab no.
Ex: Kev tawg pov thawj.
d: Hom tawg-pov thawj yog flameproof. Kuj tseem muaj hom kev nyab xeeb ntawm sab hauv, ib; nce kev nyab xeeb typ e; roj puv hom o; xuab zeb puv hom q; encapsulated hom m; thiab hom sib xyaw (feem ntau siv nyob rau hauv tawg-pov thawj faib thawv).
II: Xa mus rau qeb thib ob ntawm Cov khoom siv hluav taws xob tawg. Pawg no yog tsim rau tawg gas ib puag ncig uas tsis yog cov mines (Chav kawm I). Kuj tseem muaj chav kawm III: Cov khoom siv hluav taws xob rau cov plua plav tawg ib puag ncig sab nraum cov mines. Class IIIA: Combustible fibers; Class IIIB: Tsis-conductive plua plav; Chav Kawm III: Conductive plua plav.
B: Class IIB gas. Tseem muaj IIC thiab IIA. IIC yog qib siab tshaj plaws, muaj feem xyuam rau IIA thiab IIB. IIB yog haum rau IIA, tab sis cov qib qis tsis tuaj yeem siv cov siab dua.
T4: Cov kub chav kawm yog T4, nrog cov khoom siv qhov kub siab tshaj plaws hauv qab 135 ° C.
