摘　　要：针对旋挖钻机主卷扬系统,设计了一种滑阀式卷扬平衡阀。在台架上进行了一般性试验和可靠性试验之后,将样件装在某旋挖钻机上进行带载试验。试验过程中出现了主卷扬启动憋压、下放抖动、失速溜杆现象,分析了引起这些现象的原因,并针对性地制定了解决方案,经过优化的平衡阀达到了优越的使用效果。For the main-winch system of rotary drilling rig,designed a kind of spool valve structure winch balance valve.After the general and reliability bench test,we installed the sample valve on a rotary drilling rig to test the loading performance.In the test process,the main-winch appeared abnormal phenomena such as high pressure impact during start-up,jitter during falling-down and stall slip.We analyzed the causes and worked out solutions of these phenomena.The balance valve achieved superior using performance after optimizing.
