The temperature rise of the main motor bearing of the wire extruder is too high
Causes: (1) Poor lubrication of the bearings. (2) The bearings are severely worn.
Processing method: (1) Check and add lubricant. (2) Check the motor bearings and replace them if necessary.
Wire extruder head pressure is unstable
Cause: (1) The speed of the main motor is uneven. (2) The speed of the feeding motor is uneven, and there are fluctuations in the amount of feeding.
Solution: (1) Check the main motor control system and bearings. (2) Check the feeding system motor and control system.
Low lubricating oil pressure
Reason for occurrence: (1) The pressure regulating valve of the lubricating oil system is set to a low pressure value. (2) The oil pump has malfunctioned or blocked the suction pipe.
Solution: (1) Check the pressure regulating valve of the lubricating oil system and adjust it. (2) Check the oil pump and suction pipe.
Slow speed of automatic screen changing device or ineffective automatic screen changing device
Reason for occurrence: (1) Low air pressure or oil pressure. (2) Air cylinder leakage or hydraulic station oil leakage.
Solution: (1) Check the power system of the screen changing device. (2) Check the sealing condition of the cylinder or hydraulic cylinder.
