In this blog we are discussing three major problems that operator of co-rotating twin screw extruder machine may face.
1. Lubricating oil pressure is low in the twin-screw extruder:
The reason for the low lubricating oil pressure is mainly that the pressure setting of the lubricating oil system is too low. There is also a possibility that the pump may be faulty and the suction pipe must have been blocked. After the problem occurs, just carefully check and adjust the oil pressure in the regulator valve; check the pump and the suction pipe.
2. Head pressure instability in twin-screw extruder extrusion process:
The main causes of this problem include the uneven speed of the main motor or the uneven speed of the feed motor, causing the feed volume to fluctuate. The solution is to check the feed system motor and control system, followed by inspection of the main motor control system and bearings.
3. The main motor bearing temperature rise is too high:
Check and install the oil before the start, check the motor bearings, if necessary, replace the motor bearings.
