摘要
提出了轴承试验机液压加载系统的两种不同设计方案 .对采用先导式减压阀的限压式叶片泵加载系统和采用直动式减压阀的齿轮泵加载系统的压力稳定性、发热程度、耗电量和价格进行对比 。
Two different design projects of Hydraulic Loading Installation of Bearing Test Machine were evaluated in this paper. The compares of pressure stabilization, hot extent, electric spending and cost were put up between pilot operated pressure reducing valve with vane pump loading system and direct operated pressure reducing valve with gear pump loading system.
