Hydraulic percussive-rotary drilling technology has been widely used in the field of geological exploration; however, this technology finds less application in other drilling fields, such as petroleum, geothermal energy, coal bed gas, etc., because the pump volume, pump pressure, output impact work and impact frequency required for normal operation of existing hydraulic down-hole hammers cannot meet the requirements of the above drilling industries. In order to solve this problem, the relationship between impact energy and impact force was analyzed. The piezoelectric quartz sensor was used to measure the impact energy of hydraulic down-hole hammer with the performance test bench of hydraulic down-hole hammer developed to investigate the influence of hammer structural parameters on its input and output performance parameters so as to meet the requirements of drilling technology in different fields. The newly developed performance test bench is composed of three main modules: data acquisition and processing module, circulation power supply module and mechanical fixing module. The test bench can monitor the output impact work, impact frequency, pump volume, upper and lower chamber pressure, back pressure and other parameters without damaging the hydraulic hammer structure; thus, it can carry out further theoretical research of hydraulic down-hole hammers, improving its research level and applicable field.
