密封装置的结构与设计主要介绍锻压机械油缸的密封装置。密封的作用主要是防止液压系统中工作介质的泄漏,同时也可防止外界异物如空气、灰尘和水等进入系统。密封装置的好坏直接影响液压传动装置工作的优劣,当设计不良时,工作液体大量泄漏;系统效率下降;不能保压;操纵不灵敏;工作机构运动不稳定;机构的摩擦和磨损增加;油液漏出沾污工件,在热加工 The structure and design of the sealing device mainly introduces the sealing device of the forging mechanical cylinder. The main function of the seal is to prevent leakage of the working medium in the hydraulic system and to prevent foreign particles such as air, dust and water from entering the system. The quality of the sealing device directly affects the merits of the hydraulic transmission. When the design is not good, the working liquid leaks a lot; the system efficiency drops; the packing can not be maintained; the operation is insensitive; the movement of the working mechanism is unstable; the friction and wear of the mechanism increase; Leaking oil stains the workpiece, in thermal processing
