液压缸缓冲装配的设想准绳有哪几点?

1、液压缸活塞的活动速率在100mm/s以下,可斟酌不设置缓冲装配;在200mm/s以上时,必需设置缓冲装配。    The speed of the piston of the hydraulic cylinder is below 100mm/s, and no buffer device can be considered. When the piston speed is above 200mm/s, a buffer device must be installed. 2、双作用液压缸无杆端叛变流型缓冲装配的缓冲柱塞为凹抛物线形最为抱负,以是要只管把缓冲柱塞设想、加工成靠近凹抛物线外形(重要选用圆锥型或双圆锥型)。所谓的抱负设想为:缓冲压力稳定,活塞的加速率为常数。    The buffer plunger of a double acting hydraulic cylinder with a non bar end variable snubber buffer is the most ideal for a concave parabolic form, so the buffer plunger should be designed and machined to a concave parabolic shape (mainly conical or double conical). The ideal design is: the buffer pressure is constant, and the acceleration of the piston is constant. 3、缓冲柱塞端部不克不及撞缸底,且在结构设想时要保护好缓冲装配。    The buffer plunger end can not hit the bottom of the cylinder, and the cushioning device must be protected when the structure is designed. 4、缓冲后再启动时速率不克不及过快,更不克不及把缓冲侧(无杆端)吸空。    After the buffer is started, the speed can not be too fast, and the buffer side (no rod end) can not be emptied. 5、在有杆端设置缓冲(装配)的,其缓冲压力应制止作用在活塞杆动密封(体系)上。    The buffer pressure on the rod ends should be avoided on the piston rod dynamic seal (system). 6、相符液压缸缓冲装配设想的一样平常手艺请求。    It meets the general technical requirements of hydraulic cylinder cushion device design.
