Daily maintenance and regular maintenance of the twin screw extruder can make the life of the twin screw extruder longer. In order to meet the processing needs of a variety of materials, the screw and barrel are usually designed as a modular structure. Therefore, it is necessary to maintain the twin-screw extruder. Here are some things to pay attention to in the daily maintenance of twin-screw extruder?
1. Pay attention to regular inspection and cleaning of the machine
The basic maintenance of the twin screw extruder is to clean the machine and smooth the moving parts of the extruder. For example, there will be iron filings or other impurities from the gears in the gearbox. Check the wear conditions of the gears and bearings and make a record. Clean the gears and change the gearbox lubricants.
2. Pay attention to the operation record when operating the machine
After a period of use, a comprehensive inspection of the twin-screw extruder should be carried out. The tightness of all fixing bolts should be checked and recorded, and regular inspections should be carried out to prevent malfunctions during operation. When the twin-screw extruder changes to other materials or colors, it needs to use a large amount of cleaning material for cleaning, which requires more attention from maintenance personnel.
3. Pay attention to the working environment temperature of the control instrument and working parts to be reasonable
If there is a sudden power failure during work and the heating is stopped, when the power supply is restored, each section of the barrel must be reheated to the set temperature and kept for a period of time before the twin-screw extruder can be started and then repaired. The temperature of some parts of the twin-screw extruder is very high after long-term operation, so be careful about these things.
All in all, the daily maintenance of the twin-screw extruder should pay attention to regular inspection and cleaning of the machine, pay attention to the operation record when operating the machine, and pay attention to the working environment temperature of the control instrument and the working parts to be reasonable. The reputable twin-screw extruder should be carefully inspected during routine maintenance. When excessive scale occurs and the pipeline can not reach the cooling effect, it is necessary to take descaling and anti-corrosion measures in daily maintenance.
