聚酯熔体泵抱轴故障原因分析及改造
|
摘要
熔体泵是聚酯和纺丝生产装置的关键设备,在运行中常会出现抱轴卡泵现象,其后果十分严重。本文通过对故障案例的剖析,结合齿轮传动受力分析、动力润滑原理、轴承润滑膜几何关系及滑动轴承承载能力理论,分析总结抱轴卡泵原因及故障特征,有针对性地提出了应对措施,并进行改造,取得了良好的效果。
Melt pump was the key equipment of polyester production unit and spinning unit. Holding the shaft and sticking the pump were often occurred in the production operation, while the result was very serious. In this paper, we researched the cases of the fault, the theory of the gear transmission force analysis, the dynamic lubrication principle, bearing lubrication film geometric relationship and bearing capacity theory of sliding bearing. Finally we analyzed the causes of the shaft clamping pump, and modified it with some measures, which had a good effect.
