起重机械防爆检验方法及检验分析

防爆起重机械使用场所往往是易燃易爆的危险场所,整机防爆安全性能是保障安全运行的关键.在使用过程中其防爆性能是动态变化的,会受安装施工、检修维护、使用环境、使用时间等因素的影响.针对当前防爆起重机械使用过程中存在的防爆安全隐患以及现有检验规则中防爆要求不明细的问题,从设备选型、机械部分与电气部分防爆性能、防爆电气设备安装与线路配线等方面,分析并提出了起重机械防爆安全检验的项目与要求.

Hoisting Machineries Explosion-proof Testing Ways and Analyses

Explosion-proof crane use places are often flammable and explosive hazardous area and the whole machine explosion-proof performance is the key to ensure safe operation.In the course of service its explosion performance is dynamic and it will be affected by installation and construction,repair and maintenance,use environment,use time and other factors.Based on the explosion-proof security hazards in the course of service and the problem that the explosion-proof security inspection requirements are not detailed in existing crane inspection regulations,the explosion-proof crane safety inspection items and requirements are put forward and analyzed in aspects of equipment selection,mechanical and electrical parts explosion-proof performance,explosion-proof electrical equipment installation and wiring etc.
