| Abstract: | A spray system is one of important components of roadheaders whose operating condition exerts a direct effect on the environment of working site,the health of workers,the service life of equipment,and the safety of production.The paper offers a summary of common failures affecting spray systems of roadheaders,gives a failures tree of the system and features the calculation and analysis of a reliability of the system.Analyzing effect of base events to top event leads to the main factors influencing the system reliability.The practices are of very important value to raising the reliability of the system,improving operating performance of roadheaders,increasing useful life of the machine,and making better the environment and safety of roadheader working site. |
