| Abstract:Dual-hydraulic rotary valve in order to research the impact of the percussive drilling motion law, optimize its performance parameters, through the analysis in the phase of stroke and force of the return phase, using the finite difference method, the mathematical model of the rotary valve piston movement simulation computer program compiled by using MATLAB software, counter rotating valve piston in the simulation of the dynamic process of computing, The impact performance parameters of dual-hydraulic rotary valve drilling impactor are obtained. At the same time, the impact of the difference in the area between the upper and lower chambers of the impactor, the flow rate and pressure drop of the oil pressure system on the impact performance of dual-hydraulic rotary valve drilling impactor was studied, and the orthogonal analysis test of impact energy, impact frequency and impact power was designed. The results were optimized by design-Expert software to improve the working performance of the impactor. The results show that the piston rod diameter and pressure drop have prominent effects on the impactor performance, while the flow rate has little effect on the impactor performance. After optimization, the impact energy, impact frequency and impact power are increased by 21.88%, 12.9% and 37.6% respectively. The relevant research has certain guiding significance to the design and application of hydraulic impactor. |
