摘要
活塞杆防尘性能之优劣是考核液压缸密封可靠性的一项重要指标。通过对试验结果的分析，找出活塞杆组合密封防尘性能与各单一密封防尘性能间的内在规律性。
The dust proofness is an important index for assessing the reliability of hydraulic cylinders. Based on the analysis of the test results, the interal pattern between combined dust proofing and each single dust proofing for piston rod is revealed.
