What is the reason for excessive current in the melt gear pump?

During the use of a melt pump for extrusion, it is inevitable to encounter various problems. What we need to consider is how to deal with these problems. Excessive current in the melt gear pump can have a significant impact on both the equipment and the finished product. So, let's introduce the reason for excessive current in the melt gear pump? How should we solve it.

melt pump for extrusion

There are several reasons for the excessive current of the melt gear pump: 1. The outlet pressure is too high; 2. Excessive melt viscosity; 3. Poor assembly of shaft seal; 4. Shaft or bearing wear; 5. Motor malfunction, motor specification too small; 6. The rotating component is stuck. The countermeasures for excessive current in the melt gear pump include: 1. Check downstream equipment and pipelines; 2. Check viscosity; 3. Inspect the shaft seal and adjust it appropriately; 4. Check after parking and manually turn the car to see if it is too heavy; 5. Check the motor
