Packaging date is wrong , fuzzy replace the logo used on the identification of the laser device , detection was also found on the outer ring of these bearings have no oil groove
包装日期是错误，模糊的标识取代了正品上常用的激光图案，检测员还发现这些轴承外圈上没有任何润滑油沟。
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
摘要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。
