摘要
结合可靠性工程在液压系统中应用研究的发展现状 ,针对国内合成橡胶压块机普遍存在的液压控制系统故障率高、可靠性差、能耗高 ,经常出现导致后处理生产线停产的现状 ,研制了采用PC点对点控制的压块机专用新型二通插装阀液压系统 ,并对液压系统进行可靠性分析 .根据主机工作特点按工艺步骤建立液压系统的可靠性模型 ,利用MATLAB进行仿真 ,最后通过可靠性试验验证理论分析的正确性 ,证明液压系统设计合理、可靠性高 。
In combination with the development satus quo of applied research of reliability engineering for hydraulic system,to overcome the design limitations of traditional hydraulic control system for synthetic rubber press and such faults as high fault rate,low reliability,high energy-consume,which always caused break-down of post-treatment product line for synthetic rubber,a brand——new hydraulic system combining PC control and two-way cartridge valve for the press is developed,whose reliability is analyzed,reliability model of the hydraulic system for the press is established by analyzing process steps,and reliability simulation of each step and the whole system is carried out by software MATLAB,which was verified through reliability test.The test has proved that the theory analysis is sound.The system has characteristics of reasonable design and high reliability.It can lower the required power supply,and running energy.
