What is explosion-proof? [Explosion-proof related information] We will explain about explosion-proof.
What is explosion-proof construction? It refers to the structure of products designed to prevent explosions and fires. In "hazardous locations" such as factories, machinery and equipment must be explosion-proof (explosion-proof equipment).
Areas where there is a risk of generating a dangerous atmosphere are referred to as hazardous locations (e.g., areas where flammable gases or vapors are present or may leak). When using motors in such areas, it is necessary to select explosion-proof equipment and motors that have implemented explosion-proof measures to reduce the risk of ignition and explosion. Conditions that can lead to ignition or explosion: 1) The presence of flammable gases or vapors. 2) The presence of ignition sources and oxygen that can reach the ignition temperature of those gases or vapors in the vicinity. If any one of these can be eliminated, ignition or explosion will not occur. Types of explosion-proof structures: 1) Flameproof structure (d) ... Enclosed in a pressure-resistant container that can withstand explosions. 2) Oil-filled explosion-proof structure (o) ... The arc-generating parts are housed in insulating oil to prevent sparks from igniting. 3) Pressurized explosion-proof structure (f) ... A protective gas is continuously sealed inside the container, maintaining internal positive pressure to prevent flammable gases from entering from the outside. 4) Increased safety explosion-proof structure (e) ... A structure that increases safety to prevent sparks and localized high temperatures. 5) Intrinsic safety explosion-proof structure (i) ... A structure recognized as safe by official organizations. 6) Special explosion-proof structure (s) ... A structure recognized as safe by official organizations that does not fall under the above categories.
