一、螺杆挤压机螺杆挤压机是切片纺丝工艺的关键单元机械 ,国内外各大型化纤机械制造公司均已系列化生产 ,并着重向增大螺杆挤压熔融量 ,提高熔体混炼均化质量和节能方向发展 ,拖动采用维修简便的交流变频调速电机拖动或直流电机加调速器拖动。绝大多数切片纺化纤厂均采用单螺
First, the screw extruder Screw extruder is the key unit of the spinning process unit machinery, domestic and foreign large-scale chemical fiber machinery manufacturing company have serialized production, and focus on increasing the amount of screw extrusion melt, improve melt mixing Homogenization of quality and energy-saving direction of development, drag the maintenance of simple AC variable speed motor drive or DC motor plus speed governor drag. The vast majority of slice spinning chemical fiber plant are used single screw
