The working principle of the explosion -proof electric gourd hook is used. The explosion -proof ring chain electric gourd is a explosion -barrier type. When explosive mixtures, on the premise of ensuring safety, it is an ideal tool for improving labor conditions and increasing labor productivity.
The "explosion -proof type" of explosion -proof electric gourds refers to the flammable mixture that can withstand the flammable mixture inside the shell through the internal explosion without damage, and it will not cause an external explosive gas environment that can be penetrated into the shell. ignite. Class II factories (except under the under -class coal mine well) Electricity equipment is divided into three categories: IIA, IIB, and IIC. According to its ignition characteristics, it is difficult to sort from easy to difficult to sort: Class I ＞ IIB ＞ IIC.
Work principle of factory explosion -proof electric gourd hook: In explosive environments, especially in explosive gas environment in explosive gas environments, it is a hook device for explosion -proof electric gourds. Circles, hooks, hook beams, and hook nuts are composed of anti -loose devices and other parts. The shape and structure composition of these parts are the same as the hook device for universal electric gourds of the same specification, but they may produce machinery in them. At the area where the impact and friction were, sparkless protection was implemented.
