摘　　要：工程机械主机产品中液压系统软管总成的选型是保证整机安全可靠运行的一项重要的环节,设计人员在应用中首先应考虑软管和接头选型必须保证软管的总成最大工作压力等于或大于液压系统的最大压力,系统的脉冲压力或峰值压力必须小于软管的最大额定工作压力以及流体的化学兼容性之外,还需根据软管总成的使用综合工况选择相应的避免扭曲、以及适合安装的空间,保证软管的弯曲半径大于其最小弯曲半径参数。该文通过针对高压超柔编织管的相关结构,以及试验性能进行了系统分析,并提出了其在起重液压系统中的应用重要性。The selection of the hose assembly of the hydraulic system in the main engine of construction machinery is an important link to ensure the safe and reliable operation of the whole machine.In the application,the designer should first consider that the selection of hose and connector must ensure that the maximum working pressure of the hose assembly is equal to or greater than the maximum pressure of the hydraulic system,and the pulse pressure or peak pressure of the system must be less than the maximum rated pressure of the hose In addition to the working pressure and chemical compatibility of the fluid,it is also necessary to choose the appropriate anti twisting measures according to the comprehensive working conditions of the hose assembly,and ensure that the bending radius of the hose is greater than the minimum bending radius parameter when it is installed.In this paper,the relevant structure and test performance of the high-pressure super flexible braided pipe are systematically analyzed,and the importance of its application in the lifting hydraulic system is put forward.
