The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine will take you to know: common faults of twin screw extrusion pelletizer

The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you that many employees will encounter some failures when using the twin-screw extrusion granulator. Let's take a look at the common failures and solutions of the twin-screw extrusion granulator.

customized Parallel Twin Screw and Barrel for Pelletizer Machine products
1. The main electric starting current of the twin-screw extruder granulator is too high
Cause: The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you that the heating time is insufficient and the torque is large. A certain section of the heater does not work.
Treatment method: The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you to use the hand wheel when driving. If it is not easy, extend the heating time or check whether the heaters of each section are working properly.
2. The temperature rise of the main motor bearing of the twin-screw extruder is too high
Cause: The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you that the bearing is poorly lubricated. The bearings are severely worn.
Treatment method: Parallel Twin Screw and Barrel for Pelletizer Machine manufacturer tells you to check and add lubricant. Check the motor bearings and replace if necessary.
3. The main motor of the twin-screw extruder makes an abnormal sound
Cause: The main motor bearing is damaged. One of the SCRs in the SCR rectifier circuit of the main motor is damaged.
Solution: Replace the main motor bearing. The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you to check the thyristor rectifier circuit and replace the thyristor component if necessary.
4. The head of the twin screw extruder is not smooth or blocked
Cause: A certain section of the heater does not work, and the material is poorly plasticized. The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you that the operating temperature is set too low, or the molecular weight distribution of the plastic is wide and unstable. There may be foreign objects that are not easy to melt.
Treatment method: check the heater and replace if necessary. Verify the set temperature of each section. The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you to negotiate with the technician if necessary to increase the set temperature. Clean and check the extrusion system and the machine head.
5. The host current of the twin-screw extruder is unstable
Causes: uneven feeding, damaged or poor lubrication of the main motor bearings, a certain section of heater failure, no heating, wrong screw adjustment pad, or wrong phase, component interference.
Treatment method: check the feeder and troubleshoot. Overhaul the main motor and replace the bearings if necessary. The manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you to check whether each heater is working properly, and replace the heater if necessary. Check the adjustment pad and pull out the screw to check if there is any interference in the screw.
6. The main motor of the twin-screw extruder cannot be started
Cause: There is an error in the driving procedure. There is a problem with the main motor thread, whether the fuse is burned.
Solution: Check the program, and the manufacturer of Parallel Twin Screw and Barrel for Pelletizer Machine tells you to restart the car in the correct driving sequence. 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. If the inverter has not discharged the induction current, turn off the main power supply and wait for 5 minutes before starting. Check whether the emergency button is reset.
