| Abstract:YZX108 hydraulic hammer is successfully developed by theoretical calculation, 3D simulation and combination of experimental and field tests, the diameter specifications of YZX hydraulic hammer is perfected. Through the indoor debugging, the working parameters and the characteristics of the hydraulic hammer are determined. The production tests show that this hydraulic hammer has advantages of simple structure, stable working condition, good adaptability and large impact energy; with this hydraulic hammer, good effects can be achieved in hard rock formations such as cherty limestone, where it is hard for diamond rotary drilling. |
