Single Screw Extruder Screw and Barrel manufacturers take you to understand how to repair the extruder barrel after wear

The manufacturer of Single Screw Extruder Screw and Barrel tells you that the extruder barrel is a consumable part, but because its price is not cheap, many customers find that after it is worn, if the wear is not serious, they will try to repair it and continue. use. Today, the Single Screw Extruder Screw and Barrel manufacturer will introduce how to repair it.

Low price Single Screw Extruder Screw and Barrel from China manufacturer
The manufacturer of Single Screw Extruder Screw and Barrel tells you that because the hardness of the inner surface of the extruder barrel is much higher than that of the screw, the speed of damage and wear of the barrel is much slower than that of the screw. Most of the time the barrel is damaged because of Under long-term wear, the inner diameter becomes larger.
How can we fix this situation? The fix is ​​as follows:
1. The manufacturer of Single Screw Extruder Screw and Barrel tells you that when the diameter of the barrel increases due to wear, if the nitriding layer on the surface still exists, then the inner hole of the barrel can be directly bored and ground into a new diameter Size, replace the old screw by fine cutting, and the new screw should match the diameter of the barrel.
2. After the inner diameter of the barrel is processed and trimmed, the alloy is re-cast. The size of the alloy should be well controlled and should be controlled within 1~2mm.
3. The manufacturer of Single Screw Extruder Screw and Barrel tells you that the worn parts of the extruder barrel are uneven, and the wear is more serious in the homogenization section, so you can adopt the method of boring and trimming in this section, and equip a nitriding Alloy steel bushing, the diameter of the internal control can be determined according to the diameter of the screw.
Single Screw Extruder Screw and Barrel manufacturers tell you that the screw and barrel are very important parts in the extruder, in which the screw is a slender threaded rod, and the barrel is a relatively small diameter and long hole, but these two zero The production process of the accessories is relatively complicated, and the wear and tear occurs during the use process. The method adopted is to simply replace the new parts, which should be analyzed from a relatively economical point of view.
