This paper designed a new type of muffler for pneumatic rock drill with the theory of impedance. 利用阻抗消声原理为气动凿岩机(RD)设计了一种新型的消声罩。
The energy loss of the impact mechanism of hydraulic rock drill greatly affects drilling efficiency when it operates. 液压凿岩机(RD)工作时,冲击机构的能量损失对其效率有很大的影响。
Among the above products, Hydraulic rock drill and Hydraulic rock and concrete splitter are our patented products. 其中液压凿岩机(RD)和液压劈裂机是本公司的专利产品。
