摘　　要：针对装药设备需具备较高的本质安全度的问题,从安全设计与维护保养2方面对立式混合机进行分析。通过对桨叶、齿轮和轴承游隙进行安全设计分析,得到混合机远心桨叶的工作寿命为52 000 h,综合疲劳安全系数为6.22,安全性能较高,齿轮3能安全有效工作24 000 h,轴承选型时尽量选取高精度等级的轴承;并对控制系统安全设计措施、混合机设备维护保养进行简要阐述。分析结果表明:该研究为立式混合机的安全设计与维护保养,对复合固体推进剂预混、混合等工艺过程的安全生产提供了参考细节。Aiming at the high intrinsic safety requirement of charging equipment, analyze vertical mixer from safety design and maintenance. Through carrying out safety design for blade, gear and the bearing internal clearance, the work life of the mixer＇s axifugal blade is 52 000 hours, and safety ratio of the mixer＇s axifugal blade is 6.22, which means high security. The third axifugal blades＇ near end gear can safely and effectively work 24 000 hours. And it is necessary to choose bearings with high degree of accuracy. And safety measure of control system design and maintenance of mixer equipment were briefly discussed. The analysis results show that the safety design and maintenance of the vertical mixer provides some advice for the safety design of solid propellant premix and mix.
