Maintenance of twin screw extruder
In order to ensure the safe and stable production of the twin-screw extruder and prolong its service life, the maintenance of the twin-screw extruder must be strengthened. The basic contents are as follows:
　　 (1) Maintenance during equipment operation
Entrainment of debris is not allowed in the material, and hard materials such as metal and sand are strictly prohibited from entering the hopper and the barrel; when the cover of the exhaust chamber is opened, foreign objects should also be strictly prevented from falling into the barrel; after the extruder is heated, it should maintain sufficient insulation Time, and it should be light and quick before cranking. The screw can only be started at low speed, and the idling time should not exceed 2min. The feeder should be fed hungry before gradually increasing the speed.
　　 (2) Daily maintenance of the host
The motor oil and lubricant should be replaced after every 4000 hours of operation. If the main motor is a DC motor, the carbon brush of the motor should be checked once a month and records should be made. If necessary, the carbon brush should be replaced; the electric control cabinet should be purged once a month , Check the wear of the screw and barrel quarterly and make records; check the gears, bearings and oil seals of the gearbox once a year; when the machine is shut down for a long time, the machine should be treated for anti-corrosion and anti-fouling.
　　 After the twin screw extruder fails, it should be repaired according to the steps and methods described in the equipment instruction manual.
