Maintenance points of the extruder

After the extruder is put into production, due to the long time force load, coupled with exposure to corrosive gases and melt erosion, part of the transmission parts and the screw barrel's working performance and production efficiency will gradually decline. Pay attention to the daily maintenance of equipment, can effectively extend the life of machinery.

1. Clean and scrub the extruder on all parts of the oil and dust in the electronic control box.

2. Disassemble the gear transmission reducer, bearing gland, check the wear and tear of the transmission parts, check the quality of lubricating oil changes and timely replenishment. If the oil contains more impurities, need to filter or replace.

3. Mapping of worn gears, bearing record specifications. Manufacture or purchase spare parts in advance for timely repair or replacement.

4. Check the wear of v-belt and adjust the safety centre distance of v-belt. v-belt should be replaced if it is heavily worn.

5. Check the wear of barrel and screw. The inner surface of the barrel and screw threads round oil light scratches and friction is very, can be fine oil stone or fine gauze grinding, flat and smooth can be, record the barrel and screw working surface (i.e., the barrel and screw diameter of the inner circle of the outer circle) of the measured size.

6. Detect and correct the barrel of the actual temperature of the heating (measured by a mercury thermometer) and the instrument shows the temperature error value, in order to ensure that the extruder operates the correct control of the process temperature.

7. Adjust the safety alarm system to ensure reliability and accuracy.

8. Check the test of the liquid pipeline (water, gas, lubricating oil) the usual situation, the leakage and blocking parts of the repair and dredging.

9. Check the test whether the power supply line is firm, the electric control box and equipment safety grounding protection is firm.

10. Check whether the working position of the test heating device, cooling fan and safety cover is correct, and make necessary adjustments and corrections to ensure the correctness and effectiveness.
