摘要：

A new screw pump or extruder has been constructed with the goal of testing the drag flow analysis currently used in the evaluation of polymeric extruders. The new device has been constructed in a manner that allows the barrel, screw helix, and screw core to be rotated independently or in pairs. The experimental results of the flow produced for rotation of the barrel agree well with the theory. However, the flow produced by rotation of the screw elements does not agree with the predictions of the currently accepted theory. The experimental results indicate that the primary element that produced fluid propulsion when the screw is rotated is the screw helix. A new qualitative theory is proposed that is in agreement with the data.
