How to solve common problems in the operation of Screw Barrel For Extrusion Machine?

When solving common problems in the operation of Screw Barrel For Extrusion Machine (extruder screw), we can refer to the troubleshooting methods of general mechanical equipment and formulate solutions based on the specific problems that may be encountered. The following are some possible common problems and their solutions:
The screw does not rotate smoothly or stops
Cause: It may be caused by material blockage, screw or bearing damage, motor failure or transmission system problems.
Solution:
Clear the material blockage and check whether the feed and discharge ports are unobstructed.
Check whether the screw and bearing are damaged and replace them if necessary.
Check the motor and transmission system to ensure that the motor is running normally and the transmission chain or belt is not loose or broken.
Inaccurate temperature control
Cause: Failure of the heating system or temperature control system.
Solution:
Check the heating system to ensure that equipment such as heaters, temperature sensors and temperature controllers are working properly.
If necessary, calibrate the temperature control system or replace damaged parts.
Unstable material extrusion volume
Cause: Unstable screw speed, changes in material properties, mold wear or improper adjustment.
Solution:
Adjust the screw speed to keep it stable.
Check the material properties to ensure that the material composition and particle size are consistent.
Check whether the mold is worn or improperly adjusted, and replace or adjust it if necessary.
Excessive noise
Reason: Damage to the screw or bearing, loose transmission system or poor lubrication.
Solution:
Check whether the screw and bearing are damaged, and replace them if necessary.
Check the transmission system to ensure that the chain, belt and other components are not loose or broken, and add lubricating oil appropriately.
Equipment overheating
Reason: Cooling system failure, poor lubrication or excessive material friction.
Solution:
Check the cooling system to ensure that the cooling water circulation is smooth and the fan is running normally.
Check the lubrication system to ensure that the lubricating oil is sufficient and clean.
Adjust the material flow and screw speed to reduce the heat generated by material friction.
Other common problems
Depending on the specific equipment and usage, other problems such as electrical failure and hydraulic system failure may also be encountered. Solving these problems requires specific analysis of the causes and taking corresponding maintenance measures.
In short, when solving common problems in the operation of Screw Barrel For Extrusion Machine, we should determine the specific cause of the problem, and then take corresponding maintenance measures. At the same time, regular maintenance and maintenance of the equipment is also an effective way to reduce the occurrence of failures.
