In order to ensure the safe and stable production of the twin-screw rubber extruder and prolong its service life, it is necessary to strengthen the maintenance work of the twin-screw extruder. The maintenance methods are as follows:

1. Maintenance during equipment operation

No impurities are allowed in the material. Hard materials such as metal and sand are strictly prohibited from entering the hopper and the barrel. When opening the suction chamber cover, foreign matter should also be prevented from falling into the barrel. The rubber extruder should be kept warm after heating. Keeping time, and before the driving, the disk should be light and then start running; the screw can only be started at low speed, the idle time should not exceed 2min, and the feeder should gradually increase the speed after feeding in starvation mode.

2. Daily maintenance host

After every 4000h of operation, the oil and lubricating oil should be replaced once. If the main motor is a DC motor, check the motor carbon brush once a month, and make a record. If necessary, replace the carbon brush; the electric control cabinet should be purged once a month. Check the wear of the screw and barrel every quarter, and make a record; check the gear, bearing and oil seal of the gearbox once a year; when it is stopped for a long time, the machine should be treated for anti-corrosion and anti-fouling.

After the failure of the twin-screw rubber extruder, it should be repaired according to the steps and methods described in the equipment instruction manual.
