气提釜搅拌轴桨叶断裂及轴端磨损的原因分析

Analysis of cause for stirring shaft blade fracture and shaft end wear of stripper

气提釜是顺丁橡胶装置的重要生产设备,在生产运行中该设备的搅拌轴桨叶易发生断裂且轴端磨损严重。文中分析了该类故障的产生原因,并对桨叶强度进行了校核,实施了增大桨叶厚度等技术措施,防止了桨叶断裂及轴端磨损故障的发生。

Stripper is the important production equipment of cis-1,4-polybutadiene rubber plant, the stirring shaft blades of this equipment are prone to fracture and its shaft end is prone to severe wear. This paper analyzed the cause for this kind of faults, and made checking to the blade strength, implemented technical measures such as enlargement of the blade thickness, and prevented the occurrence of blade fracture and shaft end wear faults.
