Top Maintenance Tips For Co-rotating Twin Screw Extruder

Routine maintenance and regular servicing of the co-rotating twin-screw extruder will result in a longer life span of the twin screw extruder. In order to meet the processing needs of various materials, the screw and barrel are often designed in modular construction. Thus, the maintenance of twin screw extruders is necessary. This article provides a few tips for the daily maintenance of a co-rotating twin screw extruder.

1. Periodic inspection and cleaning of the co-rotating twin screw extruder

Cleaning the machine and smoothing the moving parts of the extruder is the basic maintenance of the co-rotating twin screw extruder. For instance, the gears in the gearbox can have iron chips or other impurities, so we need to check the wear of the gears and bearings and make records, plus clean the gears and change the lubricant in the gearbox.

2. It is necessary to keep operating records

After using it for a period of time, the co-rotating twin screw extruder should be thoroughly inspected. First of all, we should check the tightness of all the fixed bolts and make a record of them, and inspect them regularly to prevent any malfunction in operation. When the twin screw extruder switches to other materials or colors, it needs to be cleaned with a large amount of cleaning stuff, which needs more attention from maintenance workers.

3. The working environment temperature should be reasonable

If the power supply suddenly stops while the co-rotating twin screw extruder is working, the heating should be stopped immediately. When the power supply is restored, all parts of the barrel must be reheated to the set temperature and kept for a period of time before starting the twin screw extruder and then repairing it. Some parts of the twin screw extruder will be very hot after a long period of operation, so special attention should be paid to these matters.

4. Other maintenance tips

It is recommended to change the hydraulic oil once a year and clean the sludge in the oil tank. The water cooler should take timely cleaning to protect the oil temperature from increasing which will accelerate the ageing of the oil. Certainly, safety is not a trivial matter. During maintenance, the circuit safety door switch, oil line pressure relief valve, mechanical safety block, and co-rotating twin screw extruder warning light have to be checked for proper operation.

Conclusion

In a word, the daily maintenance of co-rotating twin screw extruder should focus on regular inspection and cleaning of the machine, operation records, and proper working environment temperature. A reputable co-rotating twin screw extruder should be closely checked in daily maintenance. When it happens that there is too much scale and the pipeline cannot reach the cooling effect, descaling and anti-corrosion measures should be taken in the daily maintenance.
