In the process of use of the twin-screw extruder will inevitably have problems, do you know what are the common problems? The head pressure is unstable, the main motor can not start, the main current is unstable and the lubricating oil pressure is low, the following is a detailed introduction.
1, the head pressure is unstable
causes: the main motor speed is not uniform. Or the feeding motor speed is not uniform, the feeding amount fluctuates.
treatment method: check the main motor control system and bearings. Check the feeding system motor and control system.
2, the main motor can not start
causes: the driving program is wrong. There is a problem with the main motor thread, whether the fuse wire is burned ring.
treatment method: check the program, re-drive according to the correct driving order. Check the main motor circuit. Check whether the lubricating oil pump is started and check the status of the interlocking device related to the main motor. The induction power of the inverter is not discharged. Turn off the total power supply and wait for 5 minutes before starting. Check whether the emergency button is reset.
3. The main current is unstable
causes: uneven feeding, damage or poor lubrication of the main motor bearing, failure of a certain section of heater, no heating, wrong screw adjustment pad, or wrong phase, interference of components.
Treatment method: Check the feeder and troubleshoot. Overhaul the main motor and replace the bearing if necessary. Check whether each heater is working normally and replace the heater if necessary. Check the adjustment pad and pull out the screw to check whether the screw has interference.
4, the lubricating oil pressure is low
causes: lubricating oil system pressure regulator valve pressure setting value is too low. Oil pump failure or suction YouTube blockage.
treatment method: check and adjust the lubricating oil system pressure regulator valve. Check the oil pump, suction YouTube.
or more is the introduction of the twin screw extruder common fault problems, the relevant operators in the use of twin screw extruder can refer to the above content for regular inspection, if you encounter the above problems can refer to the solution, I hope to help you.
