How to troubleshoot the feed extruder?

1. Insufficient temperature
The extruder needs to reach a certain temperature to carry out the extrusion process. If the temperature is not enough, it will affect the quality and normal production of the product. The reasons for this situation may be heating pipe circuit failure, power supply problem, temperature control system failure, etc. The solution depends on the specific reason, such as checking whether the heating pipe circuit is loose or damaged, replacing the power supply or adjusting the temperature control system.
2. Improper feeding amount
The feeding amount of the extruder will also affect the production effect. If too much or too little feeding is added, it will have an adverse effect on the product. The cause of this problem may be that the agitator speed is too slow, the feeder fails, and the feeding amount is not carried out according to regulations. The solution needs to be determined according to the specific reason, such as adjusting the agitator speed, repairing or replacing the feeder, and strictly following the prescribed feeding amount.

3. Excessive pressure
Excessive pressure of the extruder is also a common fault, which will make the production process unstable, affect product quality, and also increase the wear of the extruder. The cause of this problem may be the exhaust valve damage or the reversing valve failure. The solution needs to be determined according to the specific cause, such as repairing or replacing the exhaust valve, adjusting the reversing valve, etc.
In summary, the above faults are common faults of the extruder, but the solutions need to be determined according to the specific situation. In the daily production process, we need to strengthen the maintenance of the equipment, discover and solve the faults in time, and ensure the smooth progress of production.
