终缩聚熔体齿轮泵稳定运行探索

通过对聚酯装置增容和后接直纺长丝前后熔体齿轮泵工况变化的统计分析,研究其运行不稳定的原因,提出改造措施,包括滑动轴承润滑油槽,齿轮泵的机械密封,降低齿轮泵出口压力,改自动提速为手动提速等等。

Study on final polycondensation melt gear pump smooth running

Through the statistic analysis on the change of the melt gear pump working condition pre-and post-PET plant capacity increasing and concatenate direct spinning process,the reasons for the unsteady running were studied,the modification measures such as lubricating the oil groove with sliding bearing,mechanical sealing of the gear pump,decreasing the gear pump outlet pressure,changing the automatic speed increasing to hand speed increasing were put forward.
