介绍了热轧带钢移动式横切剪液压系统配置,简述了系统工作中存在的问题并进行了分析.相比定量泵直接供油,给出了恒压变量泵加蓄能器联合供油的系统优化方案,并对方案进行了数值计算.优化方案不仅可解决目前系统存在的问题,而且具有明显的节能效果.该方案可对类似工况液压系统的设计和改造提供参考.
Analysis of Hydraulic System Designed for Cross Cut Shear of Hot Rolled Strip
The hydraulic system designed for cross cut shear of hot rolled strip is introduced.The problems of hydraulic system are given and analyzed.The optimized design resolution is provided and calculated.The constant pressure variable pumps combined with accumulators substitute the fixed displacement pumps.The optimized design can resolve the existent problems and it' s quite effective on energy saving compared with the actual design.This study is helpful to the design and rebuilding of hydraulic systems with similar working conditions.
