摘要
本文首次给出一些液压支架冲击阀在按近10000 l/min流量冲击下的试验结果,指出这些阀在动态特性上存在的问题。结合理论推导,对这些问题进行了分析,并提出改善冲击阀动态特性的建议。
The paper described for the first time the test results of impact valves of the powered support when the flow is approximately at 10,0001/min, and the existing problems. These problems were analyzed in the light of theoretical deduction and suggestions were made to improve the dynamic characteristics of the value.
