Why does the extruder barrel screw produce noise1Why does the extruder barrel screw produce noise?
In the production process of extrusion processing, the screw of the extruder will make a noise when it rubs against the inner wall of the barrel.The reasons for this friction phenomenon are nothing more than the following four reasons:
1. The assembly gap between the screw of the extruder and its supporting transmission shaft is too large, and the center lines of the two shafts are not concentric during rotation, and the error is too large.
2. The screw of the extruder is bent and deformed, and the straightness of the center line of the shaft is too large.
3. The perpendicularity between the end face of the extruder barrel and the flange of the machine base and the center line of the barrel cannot be guaranteed, and the error is large.
4. The screw of the extruder is assembled in the barrel of the extruder, and the concentricity error of the two parts is large.
