在易燃、易爆的危险场所,防爆电梯得到了越来越广泛的使用,由于其使用环境的特殊性,防爆电梯在设计上采用了多种措施来达到防爆的要求,除了采用隔爆和本安电路两种方法以外,还需要对电梯各零部件之间的碰撞和摩擦特别注意,尽量避免碰撞火花和限制摩擦产生的温升。本文对容易产生摩擦的电梯导靴和导轨在运行中的摩擦生热问题利用ANSYS软件做了数学仿真分析,以确定其在防爆方面的性能。
In flammable and explosive dangerous places, explosion-proof elevators have been more and more widely used. Due to the special environment of their use, explosion-proof elevators are designed with a variety of measures to meet explosion-proof requirements. In addition to flameproof and In addition to the two methods of intrinsically safe circuits, special attention needs to be paid to the collision and friction between the various parts of the elevator as far as possible to avoid collision sparks and to limit the temperature rise caused by friction. In this paper, the problem of frictional heat generation between the guide rails and the guide rails of friction-prone elevator is simulated by ANSYS software to determine its performance in explosion-proof.
