As we all know, explosion-proof wire box and explosion-proof junction box are stainless steel welding or aluminum alloy casting made, and all have explosion-proof role, and the same level of protection, mainly used in chemical factories, storage and transportation, pharmaceutical industry, national defense, crude oil and other flammable and explosive places. But explosion-proof junction box and explosion-proof junction box, although only a word difference, but the structure of the composition, application scenarios, as well as the type of explosion-proof are different, the following is to tell you the difference between the two. Explosion-proof wire box role? Explosion-proof wire box role is when the distribution line is installed too long, the whole pipe is not […]

What is an explosion-proof industrial vehicle ? 1、Overview Explosion-proof industrial vehicles is a typical combination of explosion-proof electrical equipment. Explosion-proof industrial vehicles, according to the drive power classification, is divided into battery-type explosion-proof vehicles and internal combustion engine explosion-proof vehicles; according to the use of functional classification, is divided into counterbalanced explosion-proof forklift and flatbed explosion-proof trucks and so on. For battery-type vehicles, power-driven device is a DC motor, powered by the battery pack, it is a small limited electrical network, not only an independent power supply, but also the use of a variety of electrical appliances, such as electric motors, control switches, signal indicators and lighting fixtures, etc.; for

Explosion-proof principle for electrical equipment in explosive atmospheres Increased safety electrical equipment is a specialized explosion-proof type of explosion-proof electrical equipment, indicated by the symbol “e”. It is a widely used type of explosion-proof electrical equipment in industrial enterprises where flammable gases are present. It is generally accepted that when the rated voltage of the power supply does not exceed 11kV (AC RMS or DC value), under normal operating conditions or recognized abnormal conditions will not produce sparks, arcs and (or) dangerous humidity of the electrical equipment, is allowed to design and manufacture of safety-enhancing electrical equipment. Obviously, electrical equipment that does not meet these conditions is not allowed to

How can old factories be retrofitted with explosion protection? With the rapid development of industry, safety in factories is getting more and more attention. Especially in old factories, the explosion-proof problem is especially prominent due to aging equipment, outdated technology and other reasons. In order to ensure safe production in factories, explosion-proof renovation of old factories has become necessary. Causes of explosions in factories 1 Uncontrolled reaction causing an explosion Some of the wrong operation may also lead to the container of gas out of control problems, like in the power outage, water outage, the container inside the reaction heat build-up, the reaction temperature rises sharply, resulting in the container’s

Explosive dust environment, explosion-proof electrical equipment selection requirements and preventive measures Explosive dust environment explosion-proof electrical equipment selection requirements and preventive measures Dust explosion is mainly refers to the particle size less than 75um combustible dust, in a certain range of air suspension, reached the explosive limit concentration, in the open fire, high heat, static electricity under the ignition of the explosion. The power of this chemical reaction is amazing, will cause great harm to the lives of people around. And want to produce dust explosion need to have five conditions, respectively, is the source of ignition, combustible dust, oxygen, limited space, suspension. In order to prevent dust explosions in

What is an explosion-proof dust collector? First, what is explosion-proof dust collector? An explosion-proof dust collector is a type of dust removal equipment specially designed for use in explosive environments, where its main role is to control dust generated during industrial production and to clean the production site. Explosion-proof dust collector is able to prevent industrial dust explosion caused by injury, the dust explosion caused by the impact of control within a manageable range. Usually the sense of the explosion-proof dust collector is to play a role in the dust explosion, there are some things to play a role in the dust explosion before, that is, to detect the dust

What is explosion-proof camera, explosion-proof camera type What are the special features of explosion-proof cameras? Explosion-proof camera initial demand is from the coal mine, especially in the last decade, with the process of national industrialization, the demand for explosion-proof requirements to expand into various fields – petroleum, chemical industry, navigation, aerospace, metallurgy, scientific research and the military industry and other needs more. Explosion-proof cameras also began to be widely used in various fields. State and production units on the “production safety” more and more attention, how to meet the monitoring and avoid triggering the danger has become the key, explosion-proof cameras as the monitoring of the production of flammable and

Explosion-proof measures for hazardous chemicals in different states Chapter I. Prevention of gas explosions Typically, a fire starts and then gradually spreads and expands, with damage increasing dramatically with time. For the fire, the initial firefighting is still relevant. Explosions, on the other hand, are sudden, and in most cases, the explosion process is completed in an instant, and casualties and material damage are caused in an instant. In addition, the fire may also cause an explosion, because the fire in the open flame and high temperature can cause flammable materials to explode. Such as oil or explosives depot fire may cause sealed oil drums, explosives explosion; some substances at

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
