Changshu smoothly to squeeze SuChang talk extruder screw with a nitrogen-treated barrel causes of noise

In plastics extrusion processing, production of plastic extruder screw and cylinder wall friction sound, the cause of friction phenomenon reason br was caused by four reasons, changshu smoothly up to squeeze SuChang will discuss below extruder screw with a nitrogen-treated barrel caused the four factors of noise!



1, the extruder screw rod with the supporting shaft assembly gap is too big, two axis rotation work different heart, causing error;



2, extruder screw bending deformation, shaft centerline of straightness error is bigger;



3, extruder cylinder flange section and cross section and base cylinder centerline of verticality can't guarantee, error;



4, extruder screw assembly inside the extruder cylinder, beam parts great error in the communication of the



twin-screw extruder in the process of using the screw will wear, what can be done to reduce the number of twin screw extruder screw wear? First twin-screw extruder is a long time in high temperature and high pressure and high mechanical friction torque and high environment to stop working, and if the incorrect use of twin screw extruder, must reduce the working life, and affect the working efficiency of the screw extruder.
