缓冲器作为电梯重要的安全保护装置,其可靠与否直接关系着电梯安全与否。液压缓冲器由于其缓冲过程平稳且适用于任何速度的电梯,应用极为广泛。另一方面,液压缓冲器结构比较复杂,如果安装或维护保养不当,很容易出现各种缺陷。本文对液压缓冲器常见的缺陷进行探讨分析,并提出改进建议,避免缓冲器缺陷给使用者带来伤害。
As an important elevator safety protection device, the reliability of the bumper is directly related to the safety of the elevator. Hydraulic shock absorbers are widely used because of their smooth cushioning process and their suitability for any speed elevator. On the other hand, the structure of the hydraulic shock absorber is complicated, and various defects are prone to occur if it is improperly installed or maintained. In this paper, the common defects of hydraulic shock absorbers are discussed and analyzed, and some suggestions for improvement are put forward to avoid the defects of shock absorbers.
