Abstract
Aiming at the phenomena of large pressure fluctuations,relatively severe pressure impacts and others in the hydraulic support liquid supply system of Xiegou Mine during the process of daily use,it is proposed to carry out intelligent optimization and transformation on the hydraulic support liquid supply system.By studying the machine tracking process of hydraulic support,it is found that an excessively large liquid supply flow rate of the liquid supply system will reduce its service life,while an excessively small liquid supply flow rate will affect the accuracy of support control;Analyze the pressure of the current stage hydraulic support and machine tracking liquid supply system,and determine that the required liquid supply flow rate for different actions of the hydraulic support is different.The amount of fluid used is proportional to the number of brackets that require action,and the speed of pressure drop is inversely proportional to the speed of bracket action;Finally,optimization design is conducted on the overall hydraulic system and key components digital type unloading valve.According to the simulation of the intelligent liquid supply system,it is found that the optimized intelligent liquid supply system has sufficient pressure and a relatively small range of pressure fluctuation amplitude.The operating speed of the hydraulic support is significantly improved,which can effectively enhance the service life of the liquid supply system components,ensure the action control accuracy of the hydraulic support,and meet the optimization design requirements of the hydraulic support intelligent liquid supply system.关键词
