Used plastic pelletizer machine has the function of “turning waste into treasure”, WANROOETECH has been very well understood by the used plastic pelletizer production process by 10 years, and summarizes the common faults of used plastic pelletizer and the solution:

The used plastic pelletizer main motor torque is too high
Cause Analysis: Oil lubrication system fault, main motor output shaft and gearbox access shaft pair in neutral, motor and clutch vibration, etc., will damage the main motor bearings, resulting in too high torque. In addition, the feeding load is too large or the material melt may cause too high of the main motor torque.

Solution: Regularly check, clean, and form a trend graph to measure and form a trend graph to measure and form a trend graph to the main motor bearings on the lubricating oil system. If the super-trend value, the main motor empty current value or whether the power value is hypervisible, and it is determined whether the bearing should be replaced.

Regularly check the intermediate situation between the main motor output shaft and the gearbox input shaft, the first time driving or replacing the bearing is three months after three months. For electrical test examination, determine the cause of the rotor imbalance; the vibration speed test of the clutch, if the specified value is exceeded, the dynamic balance should be re-adjusted. Regular heating, cooling system for inspection, ensuring that the material is uniformly integrated. If the extruder is instantaneous, the main motor power curve and the melt pressure curve are increasing, and the amount of feeding system is too large, and the amount of feed should be reduced.

The used plastic pelletizer main motor torque is too low
Cause Analysis: Feed system faults that make the twin-screw idle will cause the main motor torque too low.
Solution: Check if the additive system or the main material processing system is faulty, clean the used plastic pelletizer blockage.

Used plastic pelletizer friction clutch failure
Cause Analysis:
1. the main motor instantaneous startup voltage is too low, friction disc, friction sheet overheating, friction plate and friction film aging, the air pressure of the friction plate can cause the clutch to disengage.
2. the friction clutch is too high;
3. friction clutch speed is too large;

Solution: When the main motor is started, the peak of electricity should be avoided, reduce the amount of feed load, the restart time is 30 minutes; in the summer, when the main motor is started twice, the main motor should be extended, or the interval time or It is forced to cool down with a fan. Wipe the wind and friction plate and friction plate surface with a gourna, and the friction plate, friction plate should be replaced if the wear is heavy or the “glassization” in the surface occurs. Verify that the air pressure value allows the friction plate to match the friction plate.

Used plastic pelletizer screw process section fault
Cause Analysis: The melt pressure is too high before and after the throttle; the mechanical head melt pressure is too high; the melt pressure difference is too large before and after the change network; the driving valve rotates the fault.

Solution: If the extruder is driving instantaneous, the main motor power curve and the melt pressure curve are increasing, the amount of feeding system is too large, and the amount of feed should be reduced.
