Twin-screw extruder: What are the common problems and solutions of the host?

by:TENGDA     2022-12-21


It is very frustrating for the twin-screw extruder to fail during normal use. For example, the current of the host is unstable, the current is too high, and the host sends out abnormalities. How to troubleshoot the host of the twin-screw extruder? This is a problem that every competent twin-screw operator must master. Today, TENGDA Plastic Extruder Machine Manufacturers of TENGDA will give you a brief introduction.







1. Reasons for the unstable current of the main engine of the twin-screw extruder:



Feeding is uneven. The main motor bearing is damaged or poorly lubricated. A section of the heater fails and does not heat. The screw adjustment pad is wrong, or the phase is wrong, and the components interfere.



The specific solution is as follows:



Check the feeder and troubleshoot. Overhaul the main motor and replace the bearings if necessary. Check each heater for proper operation and replace heater if necessary. Check the adjustment pad, pull out the screw rod to check whether there is any interference with the screw rod.



2. Reasons for the high starting current of the main engine of the twin-screw extruder:



Insufficient heating time and high torque. A section of the heater is not working.



The specific solution is as follows:



You should turn the car by hand when driving. If it is not easy, prolong the heating time. Or check whether the heaters in each section are working normally.







3. Reasons for the abnormality of the main engine of the twin-screw extruder:



The main motor bearing is damaged. One of the thyristors in the thyristor rectification circuit of the main motor is damaged.



The specific solution is as follows:



Replace the main motor bearing. Check the thyristor rectifier circuit and replace the thyristor element if necessary. The bearing of the main motor is damaged, the main motor cannot be started, The main motor bearing is damaged.



4. Reasons why the main bearing of the twin-screw extruder is too high:



The bearing is poorly lubricated. The bearings are severely worn.



The specific solution is as follows:



Check and add lubricant. Check motor bearings and replace if necessary.



The above is the introduction of the problems often encountered by the main engine of the twin-screw extruder and the corresponding solutions. If you want to know more about the extruder, please pay attention to TENGDA.
