环保节能提升助力器
本技术涉及油气伸缩设备
，具体地说是一种环保节能提升助力器。
技术介绍
众所周知，现有的气弹簧技术的专利技术及其应用已有几十年的历史，是一种可以起支撑、缓冲、制动、高度调节及角度调节等功能的新颖弹性元件。市场上销售的环保节能提升助力器种类繁多，其主要由缸筒、缸筒内的活塞和活塞杆组成。工作时，活塞杆压入缸筒内，活塞在缸筒内作轴向运动挤压油液，而油液由压缩气体使活塞达到工作位置；当加载在活塞杆上的外力消失后，则气体复原而膨胀，膨胀的气体推动活塞使活塞复位，将活塞杆移出，使气弹簧实现压缩运动和复原阻尼运动。在使用过程中，这种气弹簧存在以下问题：结构不合理，使用寿命短、维修率高，一是在使用过程中，为了保证活塞和缸筒之间气体密封，在活塞和缸筒间必须保证一定公差间隙后用密封圈密封，才能使得气体不会泄漏；二是在活塞做功过程中，为了使得活塞与缸筒之间的润滑和密封，通常将润滑油加在活塞上端面上，由于活塞在缸筒内往复运动而活塞和缸筒间公差间隙小很容易导致拉缸，进而给使用者造成不必要的维修与经济损失。
