防爆电动葫芦基本概念
Basic concept of explosion-proof electric hoist
防爆电动葫芦是我国最新防爆标准设计制造的防爆起重设备，其防爆形式
The explosion-proof electric hoist is the explosion-proof lifting equipment designed and manufactured by the latest explosion proof standards in China, and its explosion-proof form.
为“隔爆型”，该葫芦的外露防爆零部件采用特殊的无火花材料制成，防爆性能安全可靠。产品通过了机械工业部防爆电气产品质量监督检验中心的防爆性能检测，并颁发防爆合格证。
For the flameproof type, the exposed explosion-proof parts of the gourd are made of special non spark materials, and the explosion-proof performance is safe and reliable. The product passed the explosion-proof performance test of the explosion-proof electrical products quality supervision and inspection center of the Ministry of machinery industry, and issued the explosion-proof qualification certificate.
防爆电动葫芦是一种轻小型起重设备，防爆电动葫芦自重轻、体积小、起重能力大，当厂房内充有爆炸性混合物时，在保证安全的前提下是改善劳动条件，提高劳动生产率的有利工具，是生产必备的机械设备。
Explosion-proof electric hoist is a kind of small and light weight lifting equipment. The explosion-proof electric hoist has light weight, small size and heavy lifting capacity. When the explosive mixture is filled in the factory, it is a favorable tool to improve the labor conditions and improve the labor productivity. It is a necessary machine for production.
防爆电动葫芦适用于I类防爆煤矿用非采掘工作面场所和适用于II类防爆具有ⅡA、ⅡB、ⅡC级，温度组别为T1-T4组的可燃性气体或蒸汽 与空气构成的爆炸性气体混合物的场所。工作环境温度为-25℃~40℃，适合在室内使用；在室外使用时，需要加防护装置。
Explosion-proof electric hoist is suitable for I type explosion-proof coal mine non mining face and II type explosion-proof class II A, II B, II C level, temperature group of T1-T4 group of combustible gas or steam and air mixture of explosive gas mixture. The working environment temperature is -25 C ~40 C, which is suitable for indoor use.
