在需要进行电梯型式试验的安全部件中,包括安装在井道底坑的缓冲器。谈论缓冲器的作用与责任,起码一点,电梯其实已经经历了极限开关失效,超速保护的限速器和安全钳都未能有效地制停电梯,而成为电后的一道起着吸收动能减轻冲击损害的弹性缓冲安全装置,以“忍辱负重”形容确实不过分。缓冲器的忍辱负重,首先在于其能短时间内承受冲击,标准中约束了缓冲器的工作行程(制停距离)并不能很大,因为安装缓冲器的位置,电梯井道的底坑深度受到局限。根据电梯的速度考虑,不同的电梯速度,缓冲器的工作行程(制停距离)计算的结果就不同。电梯的速度与重量的组合,其实就是动能,缓冲器能够吸收动能,减轻冲击损害,反映的就是动能转化为缓冲器所能化解的一定行程(制停距离)的功,或动能转化为一定行程(制停距离)的势能理解。缓冲器的忍辱负重,还在于其确实能承受足够的冲击载荷,动载荷转化为以静态负荷衡量,缓冲器需要满足承受相应冲击 Safety components that require lift type testing include buffers installed in the hoistway pit. Talking about the role and responsibilities of the buffer, at least, the elevator has actually experienced the limit switch failure, overspeed governor and safety gear failed to stop the elevator effectively, and become a post-electric shock absorb kinetic energy to reduce the impact Damage to the elastic buffer safety device to “bite the bullet” described indeed too much. The first is that it can withstand impact in a short period of time. The working stroke (stopping distance) that is bound by the standard in the standard is not very large because the location of the buffer and the pit depth of the elevator shaft are limited. Depending on the speed of the elevator, different elevator speeds and the working stroke of the bumper (stopping distance) result in different calculations. The combination of the speed and weight of the elevator is actually kinetic energy. The shock absorber absorbs kinetic energy and reduces the impact damage. It reflects the work of converting kinetic energy into certain stroke (stopping distance) that the buffer can resolve, or the kinetic energy is converted to a certain stroke (Stopping distance) potential energy understanding. Bumpers bear the weight of boredom, but also because they do support enough shock loads. Dynamic loads translate into static loads. The bumpers need to withstand the shocks
