随着现代工业的不断发展,在石油、化工、军工等行业存在爆炸性气体混合物的场所,需要具有防爆功能的起重机。防爆起重机就是在普通起重机的基础上采取防爆措施而派生出来的产品。防爆起重机的种类很多,但防爆机理基本相同。其结构分为机械部分和电气部分,只有这两部分同时达到防爆性能要求,才可称作防爆起重机。本文阐述了隔爆型防爆起重机的防爆机理,并针对防爆起重机检验过程中发现的隐
With the continuous development of modern industry, there is an explosive gas mixture in the petroleum, chemical, military and other industries place, need to have explosion-proof crane. Explosion-proof cranes are products derived from explosion-proof measures on the basis of ordinary cranes. There are many types of explosion-proof cranes, but basically the same explosion-proof mechanism. Its structure is divided into mechanical parts and electrical parts, only these two parts meet the requirements of explosion-proof performance before they can be called explosion-proof cranes. This paper describes the explosion-proof explosion-proof crane explosion-proof mechanism, and explosion-proof cranes for the inspection process found in the hidden
