Based on the actual development of the aircraft ground hydraulic source,and aimed at the specific requirements for hydraulic pipelines of the aircraft ground hydraulic pump source,this paper outlines the hy-draulic impact phenomena, and analyzes the reasons for pipe conduit and pipe joints leakage under harsh working conditions. The improvements of hydraulic pipeline processing and assembling technology are pro-posed,which can more effectively inhibit the hydraulic oil leak,improve the reliability of the aircraft ground hydraulic pump source and guarantee the aircraft ground maintenance security than the previous technolo-gies.%根据飞机地面液压源研制实际情况，针对飞机地面液压油泵源中的液压管路特定使用要求，对液压冲击现象及管路中导管、管接头在苛刻的工作条件下产生泄漏的原因进行了分析说明。并就液压管路的加工和装配工艺提出了改进措施。对比以前的工艺方法可以有效预防液压油泄漏、提高飞机地面液压油泵源的工作可靠性，从而保障飞机地面维护安全。
