一、引言对短纤切断张力进行稳定控制,是实现短纤维长度稳定,消除纤维超长的重要保证。我公司从国外引进的年产三万吨短纤生产装置,对于切断系统外方的设计只是对切断张力进行开环粗调,而无张力控制系统,造成了生产运行中切断张力无法稳定控制,而且由于现场无张力显示,使张力调整更具盲目性,这就直接影响了短纤产品的长度偏差和超长等的质量指标。由于原切断及张力架的电机控制均采用国际上较先进的西门子SIMOVERT Master Drives
I. INTRODUCTION Stable control of staple fiber tension is an important guarantee to stabilize the length of staple fiber and eliminate excess fiber length. My company imported from abroad with an annual output of 30,000 tons of staple fiber production equipment for cutting off the design of the system is only on the cutting tension of the open-loop coarse-tuning, without tension control system, resulting in the production of cutting tension can not be stable control, And because the tension-free display on the spot makes the tension adjustment more blind, this directly affects the quality indexes such as length deviation and long length of staple fiber products. As the original cut off and the motor frame tension control are used internationally advanced SIMOVERT Master Drives
