In order to master the internal pressure variation law of the impact system of hydraulic rock drill. Drilling and tapping the cylinder block surface and the reversing valve cover surface, and reserve M10 threaded holes for installing sensors. In order to reduce the change of the internal space of the pressure chamber, the connecting aperture between the threaded hole and the pressure chamber is not easy to be too large, and the diameter is 3 mm hole connection. The installation position is shown in Figure 7.
