现代各种带材(钢材、纸卷、塑料、橡胶等)的连续生产中,经常出现跑偏现象而影响产品的质量,或者损坏设备。带材跑偏的原因很多,如设备调整欠佳、工艺参数选择不当或来料不规则等。日前,边缘位置控制系统中,利用光—电—液伺服系统的纠偏方式进行纠偏,是公认的一种较好的方法。它信号传递快,灵敏度高,反馈校正方便,适应性强。在国外,这种方式已成为系列,性能稳定,得到了广泛的应用。下面,我们简要地介绍光—电—液伺服控制系统的设计.
In the continuous production of all kinds of modern strip (steel, paper roll, plastic, rubber, etc.), the deviation phenomenon often occurs and the quality of the product is affected or the equipment is damaged. Tape deviation for many reasons, such as poor equipment adjustment, improper selection of process parameters or incoming irregularities. Recently, the edge position control system, the use of optical - electro-hydraulic servo system correction method for correction, is recognized as a better method. It is fast signal transmission, high sensitivity, convenient feedback correction, adaptability. Abroad, this approach has become a series, stable performance, has been widely used. Next, we briefly introduce the design of the electro-hydraulic servo control system.
