一、概述电—气自动调中心装置用于不断校正布料沿着联动机中心线运行,以保证机组的正常工作和卷取齐正。橡胶压延机联动装置、人造丝帘布浸胶机和锦纶帘布浸胶热伸张装置,以及其他类似的联动机组中均需应用。目前国内橡胶加工厂中所用的调中心装置一般采用气动两位式,这种两位调节装置有着结构简单,使用方便的优点。主要缺点是:由于检测系统只有两个极限信号,被控量总 I. Overview Electric - gas automatic center adjustment device for continuous correction of cloth along the linkage center line to ensure the normal operation of the unit and coiling. Rubber calender linkage, artificial silk cord dumper and nylon cord dipped hot stretching device, and other similar linkage units are required. Currently used in domestic rubber processing plant used in the center of the device generally used pneumatic two-bit, this two-position regulator has a simple structure, easy to use advantages. The main disadvantage is: due to the detection system has only two limit signals, the total controlled amount
