Check whether the lubricating oil pump is activated, and check the status of the interlocks related to the main motor. The oil pump doesn't turn on and the motor doesn't turn on. Check the procedure and restart the car in the correct driving sequence. Check main motor circuit. If the induction power of the inverter has not been discharged, turn off the main power supply and wait for 5 minutes before restarting.


Since the screw length of the twin-screw extruder is short, the material stays in the twin-screw extruder for a short time, which can avoid thermal degradation of recycled fiber and reduce power consumption. Twin-screw granulator is mainly used for filling, blending, modifying, increasing, chlorinating, polypropylene and super absorbent resins of rubber, plastics and engineering resins; degradable masterbatch, polyamide polycondensation, polyurethane adding Polymer extrusion, small models are mainly used for scientific research and teaching. The flow rate of the twin-screw pelletizing extruder is not sensitive to the die pressure, and it is more effective for extruding products of large size and area. The flow rate of the single screw granulator is more sensitive to the die pressure.


The main motor of the twin-screw extruder cannot be started, then the machine cannot work normally. This is a relatively common fault, which many people need to pay attention to.
