改良型聚碳酸酯熔体输送管道系统
摘要：
本实用新型公开了一种改良型聚碳酸酯熔体输送管道系统，包括熔体输送泵与螺杆挤出机，包括主流道和辅助流道，所述主流道包括依次由输送管道相连的熔体输送泵、第一换热器、第一静态混合器和螺杆挤出机，所述备用流道包括依次由输送管道相连的熔体输送泵、第二换热器、第二静态混合器和螺杆挤出机，还包括控制该备用流道开启和主流道关闭的控制系统，从而降低输送管道出口处的输出压力，进而降低聚碳酸酯熔体的出口压力，使得熔体分布均匀提高了产品的品质，并且当主流道发生问题时，可以自动切换到辅助流道。
摘要（英）：

The utility model discloses an improvement type polycarbonate fuse -element pipeline system, including fuse -element delivery pump and screw extruder sprue and supplementary runner, the sprue includes in proper order by continuous fuse -element delivery pump, first heat exchanger, a static mixer and the screw extruder of pipeline, the control system who closes with the sprue is still opened including this reserve runner of control including in proper order by continuous fuse -element delivery pump, second heat exchanger, the 2nd static mixer and the screw extruder of pipeline to reserve runner to reduce the delivery pressure in pipeline exit, and then reduce the outlet pressure of polycarbonate fuse -element, make the fuse -element distribute and evenly improved the quality of product, and when the sprue takes place the problem, can automatic switch -over to supplementary runner.
