卧管式PA66缩聚液压系统的改造探讨

Technical renovation on hydraulic system for horizontal piping PA66 polycondensation process

介绍了聚酰胺66(PA66)缩聚生产线驱动设备由电动控制替代液压控制的改造实施方案。结果表明:PA66缩聚生产线驱动设备改为电动控制后,选用XWDV-6闪蒸泵电机,WXE-108G型螺旋电机和Sie-mens变频器,提高了产量,聚合产量由600 kg/h提高到850 kg/h,可满足下游3台纺丝机开车,避免了液压控制由于转速低导致的漏料现象,提高系统稳定性,节约生产成本。

The renovation plan that an electricalcontrolling system replaced the hydraulic controlling system as the driving equipment was introduced for polyamide 66（PA66） polycondensation line.The results showed that the polymerization output was increased to 850 kg/h from 600 kg/h as flash pump motor XWDV-6,screw motor WXE-108G and Siemens frequency converter were used in the renovation,which assured the full operation of three down-stream spinning equipments.The electricalcontrolling system avoided the material leakage resulting from the low rotary speed of hydraulic system saved the production cost and improved system stability.
