Machine Introduction
The optimal impact efficiency of each impactor has its matching optimal shaft pressure and speed. During the drilling process, as the number of drill pipes increases, the axial pressure on the impactor also increases. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more suitable axial pressure. At this time, the impact efficiency is higher.
