恒压式变量柱塞泵的改进

Improvement on constant-pressure axial variable piston pump

针对一台德国大型中空设备在实际中遇到的问题进行了分析,对设备中恒压式变量柱塞泵的变量机构进行了改进,将弹簧弹力调节改为弹簧弹力和比例压力阀的压力共同调节,并对改进后的系统进行仿真分析.改进后的系统解决了设备故障,并达到了节能的效果.

A technical problem encountered during the operation of a large-scale German middle-hollow equipment was analyzed. The displacement variation mechanism of a constant-pressure axial variable piston pump in that equipment was improved, spring-regulation in it being modified to be combined regulation with spring and proportional pressure valve. The improved system was analyzed with computer simulation. By using this improved system, the trouble with the equipment aforementioned is solved and the effect of power-saving is achieved.
