基于二通插装阀的换辊装置液压控制回路故障分析及优化

摘要

简要阐述了某万能轧机换辊装置的工艺要求、原设计的液压控制回路及二通插装阀的工作原理，对使用过程中的故障进行了分析与排查，并提出了优化后的控制回路。从使用效果来看，回路优化后故障彻底消除。%The technical requirements of roll change device for a certain universal mill and the original hydraulic control loop, and the working principle of 2-way cartridge valve were described.Further analysis and survey on the fault in operation were made and the optimized control loop was put forward.In effect, after optimization, the fault in application is removed completely.
