Simulation Study on Low Pressure Loss Integrated Manifold of Straw Baler Hydraulic System
摘要
Abstract
In conventional hydraulic systems,machined integrated valve blocks are commonly used to consolidate hydraulic valves with diverse functions.However,the presence of numerous process orifices and cutter-tip cavities within these blocks leads to substantial local pressure losses and frictional losses,resulting in elevated energy consumption.In order to reduce energy loss,reduce weight,and save costs,this study uses casting to integrate the main functional valve body and oil circuit into one,and designs a new low-pressure loss integrated valve group.Through CFD simulations employing a liquid-gas two-phase flow model,we conducted comparative analyses of pressure losses between conventional and redesigned configurations.The results demonstrate that the optimized manifold design achieves over 50%reduction in pressure losses while maintaining full compliance with the original hydraulic system's operational requirements.关键词
