What needs to be paid attention to during the operation and debugging of the extruder-2

6. The screw dry run test should not exceed 30min, connect the die head and pelletizing equipment after everything is normal, install the connecting bolts for the die head, and apply a layer of molybdenum disulfide or silicone oil before use to facilitate disassembly.

7. In the early stage of feeding production, the minimum working speed of the screw should be used to feed less and evenly, and check whether there is any abnormality in the swing of the working ammeter pointer of the motor used for driving the screw at any time.

8. After the extruder is put into normal production, the operator should always check the temperature change of the bearing part. When checking the temperature of the motor and each bearing part, gently touch the inspection part with the back of your finger. Do not touch any rotating parts with your hands during the operation of the equipment.

9. When disassembling and installing screws and molds, do not use heavy hammers to directly hit the parts, and if necessary, pad hardwood and then tap to disassemble or install.

10. When cleaning the residual materials on the screw, barrel and mold, it must be cleaned with bamboo or copper knives and brushes, or clean with professional washing and air washing equipment, and avoid scraping the residues with steel knives or continuously grilling parts with fire. Or use a special screw cleaner for non-dismantling cleaning.

11. When dealing with the fault of the extruder, the extruder is not allowed to run running. When the extruder screw rotates and adjusts the mold, the operator is not allowed to face the extrusion barrel mouth to prevent accidents.

12. When the extruder is in production, the operator is not allowed to leave the post, and if he has to leave, the extruder should be stopped.

13. Disassemble the screw after parking, and apply a layer of anti-rust oil after the residual material is cleaned up, if it is not used temporarily, it should be bandaged and hung vertically in a dry and ventilated place.

14. The extruder and accessories that have been out of production for a long time should be coated with anti-rust oil and sealed the inlet and outlet orifice to prevent foreign matter from entering.
