摘要
本文分析了 YBPD—63型恒压式变量叶片泵的配流盘结构,产生调节内力的原因及其不良影响,并作了某些改进,使改造后的负荷传感功率匹配泵的工作性能有了明显改善。
This paper analyzes the valve structure that produces an adjusting force and gives an unfavourable effect on the constant—pressure variable— displacement vane pump model YBPD and suggests some improvements on it.Owing to the modification,the working characteristics of the load— sensing power matching pump have been considerably bettered.
