Shenhai Explosion-Proof
Kahulugan:
Kung ikukumpara sa pangkalahatang pang-industriya at domestic na mga de-koryenteng kagamitan, Ang mga de-koryenteng device na hindi lumalaban sa pagsabog ay dapat may mga kinakailangang marka upang ipahiwatig na ang mga ito ay isang uri na hindi lumalaban sa pagsabog. Ito ang tinatawag na explosion-proof marking.
Layunin:
Each explosion-proof electrical device should have its explosion-proof marking clearly displayed on its visible parts and nameplate. This system provides essential information, indicating that the marked electrical equipment is explosion-proof and specifying the types of nasusunog na gas environments and hazardous areas where it can be safely used. Malinaw, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: Hal (Explosion-protect) represents “pagsabog-patunay,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (o temperatura), and/or equipment protection level symbol (o temperatura).
The representations of the uri ng pagsabog (d, e, i, p, o, q, m, n, s), equipment classification (ako, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, Ga; Ma, Mb, Gb) are well-established. Kaya, we use these representations to exemplify the composition of explosion-proof markings for different types of explosion-proof na mga de-koryenteng kagamitan.
