| Abstract: | The impact hammer of a hydraulic rock drill is a mechanism with high pressure and high frequency. Its seal performances affect the efficient,energy consumption and steadiness of the rock drill.The three-step discribed in this paper,which consist of gap seal,oil return channel with low pressure and seal ring,have good effects. |
