Abstract

Provided is test equipment for flow field characteristics of a screw extruder. The test equipment comprises a collection controller, a controllable display device and a flow field test cylinder, wherein the flow field cylinder comprises a machine cylinder and a detection device, the detection device is movably arranged in the machine cylinder, the detection device is electrically connected to the collection controller, and the collection controller is electrically connected to the controllable display device. The test equipment for the flow filed characteristics of the screw extruder has the advantages that the test equipment can collect physical characteristics under different states of materials in the screw extruder, thus conducting collection on flow filed characteristic information such as speed, temperature, pressure, shear force and viscosity of the materials in the machine cylinder comprehensively and effectively; in addition, the test equipment can achieve displacements of different positions and different depths in the machine cylinder. In the test process, the test equipment can test multiple sets of real-time flow field data of different positions and different depths so as to achieve accurate test of the flow field characteristics of the screw extruder in the extruding process.

Description

technical field [0001] The invention relates to a testing device for flow field characteristics of a screw extruder. Background technique [0002] At present, in the plastic machine industry, screw extruders account for about 15-30%. More and more screw extruders are going to the world stage. To study screw extruders, you first need to know the extrusion process of screw extruders. How to accurately measure the material characteristics and flow field parameters of the material in the screw extruder is extremely important, and it also lays an important foundation for further research on the characteristics of the screw extruder and improving the extrusion performance of the screw extruder. However, there are no relevant research reports on the relevant test system at home and abroad, so designing a screw extruder flow field characteristic test equipment has certain significance for the development of domestic plastic machines. Contents of the invention [0003] The technic...
