Abstract
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.关键词
