Explosion-proof shutter door

According to relevant experts, the corresponding measures depicted by the electrical circuits and moving parts of the fire shutter doors met the relative requirements of the testing regulations and explosion protection systems. This is a national explosion-proof electrical product quality supervision and inspection and testing center inspection qualified and issued an explosion-proof certificate, and issued a full set of shutter doors explosion-proof certificate that is "Fire and explosion-proof shutter doors" certificate.

Explosion-proof and fireproof rolling shutter Wenwen Shengyi is manufactured with the scope of description of the "drawing and fire risk environmental power equipment drawing specification" and the "general skill conditions of fireproof and explosion-proof rolling shutter".

Explosion-proof shutter doors are based on steel shutter doors, curtains and transmission components to be modified, together with explosion-proof electrical and other equipment, and then complete the explosion-proof effect: Explosion-proof motor controlled by the explosion-proof electric control box, drive the reel through the variable speed device to make the shutter door closed.

In the relative movement of the machine, the coupling is used instead of the sprocket drive, and the friction in the track is inlaid with copper or nylon. It is best suited to use or store environments such as flammable gas, evaporative chemicals, and other factories with high-firing materials, warehouses, and the like, which are capable of exhibiting the risk of blasting fires.
