Answers to possible problems of twin screw plastic extruderIn the process of twin-screw plastic extruder extrusion, the causes of various problems may be solved in time. I have compiled some common questions for your reference.
1. Low lubricating oil pressure during the operation of the twin screw extruder
The main reason for the low lubricating oil pressure is that the pressure setting of the lubricating oil system regulator valve is too low or the pump is exhausted and the suction pipe is blocked. Just carefully check and adjust the lubricating oil system pressure regulating valve and check the oil pump suction pipe.
2. Unstable water head pressure during the twin screw extruder
The cause of the problem includes uneven speed of the main motor or uneven feed rate of the speed fluctuation of the motor. The solution is to check the motor feed system and control system, and the second to check the main motor control system and bearings.
3. The temperature rise of the main motor bearing is too high
Poor bearing lubrication and severe bearing wear cause the temperature rise of the main motor bearings to be too high. Check the lubricant and check the motor bearings.

4. Abnormal noise of twin screw extruder
The main motor bearing is damaged, or the motor thyristor rectifier circuit is damaged, which will cause abnormal noise. The solution is to replace the main engine bearing or replace the damaged thyristor circuit component.
