| Abstract:High-performance hydro-hammer adopts the working principle of volumetric double effect; it has the characteristics of single high impact energy and low pump pressure. Laboratory experiments have showed that the structure design of high-performance hydro-hammer is reasonable and the performance and technical indicators have reached the design expectations. The hammer can output single high impact energy and has the characteristics of high impact frequency and low pump pressure also. The field tests have showed that rapid and efficient full face drilling in hard rocks can be realized by the combination of high-performance hydro-hammer and spherical crown button bits. |
