Common faults of plastic extruder and abnormal noise of treatment methods
(1) If it occurs in the reducer, it may be caused by bearing damage or poor lubrication, or it may be caused by gear wear, improper installation and adjustment or poor meshing. It can be solved by changing bearings, improving lubrication, changing gears or adjusting gear meshing.
(2) If the noise is a sharp scraping sound, the possibility of scraping between the shaft head and the transmission shaft sleeve caused by the deviation of the barrel position should be considered. It can be solved by adjusting the barrel.
(3) If the barrel makes noise, it may be that the screw bends and sweeps the bore or the set temperature is too low, which may cause excessive friction of solid particles. It can be treated by straightening the screw or increasing the set temperature. Professional plastic extruder chooses shuangjun machinery
