With the increasing emphasis on industrial safety, more and more ordinary industrial products are improving towards explosion-proof products. Ordinary products reachExplosion proof standardExplosion proof rectification must be carried out and an explosion-proof certificate must be obtained. The same applies to modular complete sets of equipment. Generally, all components of the product that are powered on must be replaced with products with explosion-proof certificates, such as electrical instruments and meters such as power distribution, sensors, controllers, etc., and installed together in an explosion-proof box. Of course, the explosion-proof level of this explosion-proof box must correspond to the hazardous environment on site, and the same applies to other explosion-proof components purchased.

The line comes out of the explosion-proof cable clamping and sealing joint of the explosion-proof box. If the wiring port on the other end of the factory is installed in a hazardous area, it is also required to have an explosion-proof cable clamping and sealing device for wiring. If there is an impact hazard on site, an impact resistant explosion-proof flexible pipe is also needed. Replace the motor of the power source with an explosion-proof motor, the sound and light alarm with an explosion-proof one, the fan with an explosion-proof one, sensors, and so on.

Requirements for Applying for Explosion proof Certificate for Combination Explosion proof Equipment

Explosion proof equipment composed of various explosion-proof components does not need to consider the thickness of the surrounding steel plate. Generally, it is necessary to send the product manual, assembly drawing, and on-site environment to our professional personnel for review and judgment. Any areas that do not meet the standards need to be rectified until they are qualified. The final explosion-proof rating is composed of the explosion-proof markings of each component.
