爆炸危险场所用电梯危险点燃源辨识及预防措施

易燃易爆危险场所用防爆电梯除具备普通电梯性能外还必须满足防爆安全要求.依据GB 25285.1—2010,从爆炸预防的基本原理系统分析了防爆电梯运行过程中可能形成的电气火花、危险高温、机械摩擦、碰撞、静电等危险点燃源及预防措施.

Dangerous Ignition Source Identification of Elevator Used in Explosive Dangerous Sites

Explosion - proof elevator used in inflammable and explosive dangerous sites belongs to the complete sets of mechanical and electrical special equipment, which not only have elevator performance but also meet the explosion - proof safety requirement. Explosion protection safety performance of explosion - proof elevator system is the key to prevent dangerous ignition source and guarantee the safe operation. According to GB 25285.1-2010 and from the basic principle of explosion prevention, systematically analysis the electric spark, danger chanical friction and collision, the static electricity and other dangerous tive measures in the process of explosion - proof elevator. and high temperature, chanical friction and collision, the static electricity and other dangerous ignition source and preven- tive measures in the process of explosion - proof elevator.
