Explosion -proof gourds are very extensive in some flammable and explosive dangerous places, and they are guaranteed in terms of safety and work efficiency. The environmental conditions and materials of explosion -proof gourds are as follows:

The environmental conditions of explosion-proof gourds: explosion-proof gourds are usually operated indoors, the working environment temperature is -20-40 ° C, the relative humidity of the air is not greater than 85%(when the ambient temperature is 25 ° C), the altitude should not exceed 1000m; When working in the gas environment, its working area is 1 or 2 districts divided into GB3836.14-2000; when explosion-proof gourds are working in combustible dust environment, their working area is area 21 or 22 specified in GB12476.3-2007 Areas; explosion -proof gourds should have good ventilation, and necessary facilities should be guaranteed.

Materials for explosion -proof gourds: Product signs or tonnage cards are made of brass or stainless steel, and their thickness should not be less than 1mm; when the explosion -proof level is IIC, the wheel pedal and margin part should be used for not bleaching the explosive gas mixture due to impact and friction. Made in copper alloy or other sparkless materials; explosion -proof electric gourd cable rolling wheels and running -and -the -operating stroke -limited switches should be made of engineering plastics with bronze, brass or surface resistance than 109Ω. At this time, the traction line of the cable should be stainless steel wire rope; the rubber buffer shall comply with the regulations of JB/T8110.2, polyurethane buffer shall comply with the regulations of JB/T10833, and the surface resistance shall not be greater than 109Ω. Explosion -proof electric gourds in the operation method should be used for no sparkling materials.
