摘　　要：介绍一种浆纱机上浆率在线自动控制系统。详细说明了上浆率在线自动控制的原理。压出加重率采用实验法测得,浆液含固率由含固率检测仪检测得出。通过改变直接、间接加热管中蒸汽流量,控制浆液含固率的变化,实现对上浆率的实时在线调控。控制方法采用PID控制,根据上浆率标准值与实际值的差值,通过PLC、比例压力阀及蒸汽流量控制阀精确控制,且可在触摸屏上显示上浆率实际值。结果认为:该系统能够满足上浆率实时在线自动控制和在线显示的要求。An online automatic control system of sizing percentage is introduced, and the principle of online automatic control system isexplained in detail. The extrusion weighting percentage is measured by experimental, and the solid content in sizing is tested by solid contentdetector. By changing the steam flow in direct and indirect heating tube, the change of solid content in sizing can be controlled to realize thereal-time online adjustment of sizing percentage. PID control is taken, and the actual value of sizing percentage can be displayed on the touchscreen by precise control with PLC control, proportional pressure valve and steam flow control according to the difference between set valueand actual value of sizing percentage. This online automatic control of sizing percentage can meet the requirement of real-time control of sizing percentage.
