彈簧疲勞拉力機的特點及用途

Features and usespring fatiguetensile machine

機械式彈簧疲勞拉力機是由驅動係統、傳動係統、控製顯示等係統組成，適用於各 種螺旋彈（dàn）簧的疲勞性能試驗。該拉力（lì）機由電磁（cí）調速（sù）係統控製電機運行，通過偏心裝置（zhì）帶動連杆使 壓板往複上升、下降，完成（chéng）對彈簧的往複壓縮（suō）疲勞拉力試驗。該機無汙染、效率高，具有較寬的調（diào）頻 範圍和試驗空間，配上合（hé）適的輔具，可完成不同規格的彈簧疲（pí）勞試驗。該（gāi）拉力（lì）機通過單片機控製，實現試驗（yàn）次數達到（dào）自動停機功能，該機集成度高，結（jié）構簡單，故（gù）障率低，性能穩定、可靠，操作 簡單。
