Common Problems And Solutions Of Extrusion Of Twin Screw Extruder
Aug 08, 2017

1, the twin-screw extruder running process lubricating oil pressure is low

The reason for the low lubricating oil pressure is mainly that the pressure setting of the lubricating oil system is too low or the pump is faulty and the suction pipe is blocked. After the problem occurs, just carefully check and adjust the oil pressure regulator valve; check the pump, suction pipe.

2, twin-screw extruder extrusion process head pressure instability

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

Bearing lubrication and bearing wear are serious cause of the main motor bearing temperature rise is too high reasons, check and install the oil before the start, check the motor bearings, if necessary, replace the motor bearings.
