Coal mine explosion-proof inspection standards I. General provisions:     1. In order to further implement the “Coal Mine Safety Regulations” and the standards and regulations on explosion-proof electrics, to improve the understanding of electromechanical workers on the performance of explosion-proof electrics, and to facilitate the mastery of the use of the standards in practical work, so as to strengthen the scientific management of explosion-proof electrics in underground coal mines, to improve the quality of maintenance, to eliminate the electrics failure, and to realize the safe operation of electric equipments, the “Rules” are formulated.     2. All underground electrical equipment (including small electrical equipment) must be selected in accordance […]

Arrangement and explosion protection of explosion-hazardous plants and warehouses Layout and explosion protection of explosion-hazardous silos and warehouses I. General layout 1. Explosion risk of Class A, B plant, warehouse should be set up independently, and should be open or semi-open, its load-bearing structure should be reinforced concrete or steel frame, row structure. 2. explosion-hazardous plant layout preferably rectangular, and the prevailing wind direction should be perpendicular or angle of not less than 45 °, in order to effectively utilize the penetrating wind to dissipate explosive gases in the mountainous areas should be arranged on the windward side of the hillside and well-ventilated places. 3. explosion-proof plant should be set

Explosion-proof junction box introduction and application Explosion-proof junction box In industries such as petroleum, chemical, coal mining and metallurgy, there are often scenarios of combustible gases or dusts in the production chain, which are flammable, explosive and dusty environments. Ordinary electrical equipment in the operation process, if an electric spark, will inevitably cause combustion or explosion, resulting in significant casualties and property damage. How can electrical equipment be used safely in these environments? Explosion-proof products came into being, explosion-proof cabinet is a very important electrical products, which in addition to preventing fire or explosion, but also to prevent dust, moisture, smoke and other pollutants into. Compared with the civil junction

What is an explosion-proof motor? Why are they explosion-proof? In the field of industrial production, especially in those environments where flammable and explosive substances exist, explosion-proof motors play a vital role. It is a specially designed and manufactured motor equipment that can operate safely in places with explosive hazards. I. What is an explosion-proof motor? Explosion-proof motors may look similar to ordinary motors from the outside, but there are strict requirements in terms of internal structure, component materials and manufacturing process. Its shell is usually made of high-strength metal materials, such as cast steel, cast iron, etc., with a high degree of sealing, which can effectively prevent the internal sparks,

Which locations require explosion-proof electrical testing? Why do I need an explosion proof test? 一、It’s safety and security. In places where there are flammable and explosive gases, dust and other hazardous substances, such as petrochemical, coal mine underground, grain storage and other environments, the operation of electrical equipment may produce electric sparks, arcs or high temperatures, with the risk of triggering an explosion. Through testing can ensure the normal operation of explosion-proof electrical equipment, reduce the possibility of explosion accidents, to protect the lives of personnel and corporate property safety. Many industry-related laws, regulations and standards mandate regular testing of explosion-proof electrical equipment, for example, in hazardous chemical production and

What explosion protection measures are available for industrial buildings? Relevant general building fire codes 2.1.5 The layout of the production process and the control of the production process in the plant, the design and setup of the process devices, equipment and instrumentation, materials, etc., shall take appropriate fire prevention and explosion-proof measures in accordance with the fire hazards of the production parts. 2.1.7 The building has combustible gases, vapors, dust, fibers explosion hazardous places or parts, should be taken to prevent the formation of explosive conditions of the measures; when the use of pressure relief, decompression, structural anti-explosive or anti-explosive measures should be used to ensure that the main load-bearing

What are the principles of connecting explosion-proof distribution boxes with galvanized pipes? 7 principles of connecting explosion-proof distribution box with galvanized pipe: 1 The requirements for laying explosion-proof pipes are higher than those for laying ordinary open pipes. Need to use thick-walled pipe (galvanized water pipe), each connection also has special requirements. 2 Pipes and pipes need to be connected with junction boxes and switches using threaded connections, and explosion-proof junction boxes and explosion-proof switches need to be used.3 Steel pipe needs to have sufficient strength and protection, and its wall thickness is not less than 2.5. 4 When pipe clamps are used to connect steel pipes, lock nuts should

Chemical plant explosion-proof requirements and part of the required explosion-proof products Explosion protection requirements for chemical plants include the following: Requirements for equipment and facilities: Electrical equipment must comply with national electrical explosion-proof standards, and the configuration must match the regional hazard level and be regularly inspected and maintained. Lightning protection and electrostatic conductivity facilities need to be installed, configured and tested annually in accordance with the regulations, in order to prevent static electricity buildup from causing fire or explosion. Production equipment and devices must be equipped with safety facilities in accordance with national regulations, and the equipment and pipelines should be made of fireproof materials and comply with relevant

Explosion-proof junction box knowledge What is an explosion-proof junction box? Explosion-proof junction box is a kind of explosion-proof and strong sealing connectors for circuit laying. From the appearance of a closed box. When the cable passes through it, the locking mother in and out, connection, thus effectively avoiding the phenomenon of sparks will occur in the connection. And its shell will usually use aluminum alloy to make, at the same time in order to make it better with fire resistance and corrosion resistance, often also in its surface to the spraying of some. The role of explosion-proof junction box Explosion-proof junction box is generally made of metal. Its role is
