摘要

针对采棉头液压系统振动、泄漏、噪声大、管路结构复杂等问题,在原有液压系统基础上,设计了采棉头举升液压阀块.利用Fluent软件对液压阀块典型孔道进行仿真分析,研究液流在阀块孔道内部流动特性,对液压阀块孔道结构进行优化,减少压力损失,提高能量利用率.同时根据优化结果加工出阀块并进行了试验验证,阀块内部典型孔道压力损失与仿真结果基本吻合,为液压阀块优化设计提供了参考依据.
        In view of the problems of vibration,leakage,large noise and complicated pipeline structure of the hydraulic system of the cotton picking head,the picking head lifting hydraulic valve block was designed based on the original hydraulic system.Simulation analysis of typical holes of hydraulic valve blocks using fluent software.Study the flow characteristics of the liquid flow inside the valve block orifice.Optimize the pore structure of the hydraulic valve block to reduce pressure loss and improve energy utilization.At the same time,the valve block is machined according to the optimization result and tested and verified.The typical pore pressure loss inside the valve block is basically consistent with the simulation results.Provide reference for the optimization design of hydraulic valve block.
