液压锁对钢珠自锁液压缸性能的影响及改进方法

The Influence and Improvement of Hydraulic Lock for Steel Ball Self-locking Hydraulic Cylinder

针对某特种车辆液压系统在调试过程中出现的油缸误动作进行了故障分析,简单介绍了由双向液压锁和钢珠自锁液压缸组成的锁紧控制回路的工作原理,试验结合理论分析了该液压系统设计存在的不足和故障问题出现的原因,提出了锁紧控制回路的各种改进方案,并进行了可靠性分析,确定了合适的改进方案,最后通过试验验证了改进方案的正确性和可靠性。

For the malfunction of rear hatch covers oil cylinder appeared in the debugging process of special vehicle hydraulic system,this paper analysis the hydraulic failure.The working principle of locked control circuits is simply introduced,which is composed of two-way hydraulic lock and steel ball self-locking hydraulic cylinder.Combined with experiments and theory,the paper analyses the defects in the design of the hydraulic system and the causes of failure,then various of the improvement projects are put forward,and analyses the reliability of hydraulic system.Finally determined the appropriate improvement,then its correctness and reliability is verified by tests.
