O形密封圈适用于装在升降平台升降平台上，在规定的温度、压力、以及不同的液体和气体介质中，于静止或运动状态下起密封作用，O型密封圈是液压与气压传动系统中使用最广泛的一种密封件。下面济南天锐升降机械的有关专家就给大家详细介绍一下液压缸O型圈的特点。

1、O形圈密封性能优良，工作寿命高，动态压力密封工作寿命比常规橡胶密封制品高5—10倍，最高可达数十倍，在某些条件下可与密封基体同寿命；O型圈高耐磨，密封面磨损后具有自动弹性补偿功能。
Lift manufacturers introduce O-ring sealing performance, working life high dynamic pressure seal 5-10 times working life than conventional rubber seal products, up to a few times, under certain conditions, with the seal matrix with life; O high wear-ring sealing surface elasticity worn with automatic compensation.

2、O型圈具有良好的自润滑性能，可作无油润滑密封，O型圈结构简单，安装方便。
O-ring analysis elevator manufacturers have good self-lubricating properties, can be used for non-lubricated seals, O-ring structure is simple and easy to install.

3、O型密封圈主要用于液压缸静密封和往复运动密封。用于旋转运动密封时，仅限于低速回转密封装置。O型密封圈一般安装在外圆或内圆上截面为矩形的沟槽内起密封作用。O型密封圈在耐油、酸碱、磨、化学侵蚀等环境依然起到良好密封、减震作用。
Speaking lift manufacturers O-ring is mainly used for static seals and hydraulic cylinder reciprocating seal. For rotational movement of the seal when limited to low-speed rotary sealing device. O-ring is usually installed on the outer or inner circle from the seal section is rectangular trench. O-ring seals still play a good shock absorption in oil, acid, wear, erosion and other environmental chemistry.
