63 MN油压机提升缸液压回路的设计改进

摘要

介绍了大型油压机提升缸液压回路的工作原理,分析了其存在的问题,并提出了改进方案,有效解决了大流量高压力油压机液压系统冲击大对安全溢流系统的损坏问题.%The work principle of hydraulic circuit in the pull-up cylinder of large hy-draulic press was introduced, existing problems analyzed and an improvement program was put forward, which effectively solved the problem of damage to the safe overflow system by exces-sive impact of the hydraulic system of big flow high pressure press.
