摘要
采用针盘式往复摩擦仪和液压密封测试机对聚氨酯液压密封进行耐磨性能分析,与现场实际磨损情况进行比较,来确定液压密封的磨损加速试验方法;但是采用液压密封测试机有显著压缩量,采用降低磨损的变色和氧化铝颗粒液压油经往复型针盘式摩擦仪测试则密封面的磨损加速系数2.1～3.4。此实验有益于液压密封耐磨加速实验损设计和PU密封件设计。
The wear characteristics of polyurethane(PU)hydraulic seal were tested by seal tester and a pin-on-plate reciprocating tribo-tester,and compared to field data.Although a significant compression set was observed,the discolored lubricant and the lubricant with alumina particles used for testing using the pin-on-plate reciprocating tribo-tester.The height decrease data showed that the wear was accelerated by factors of 2.1~3.4 and the experiment could be available for designing of reliable accelerated life testing for hydraulics.
