The manufacturer of Screw and Barrel for Extruder will show you: the maintenance of extrusion screw
The manufacturer of Screw and Barrel for Extruder tells you that during the non-stop operation of the extruder screw, the internal parts of the extruder inevitably wear out, which directly leads to a decrease in production efficiency. In response to this bad phenomenon, related industries have proposed corresponding maintenance of the extrusion screw. So what are the work contents of extrusion screw maintenance? Next, the manufacturer of Screw and Barrel for Extruder will take you to find out!
The manufacturer of Screw and Barrel for Extruder tells you that after the extruder screw is put into production, due to long-term dynamic load operation, coupled with exposure to corrosive gas and melt erosion, the operation function and production power of some transmission parts and screw barrels will gradually The land has changed, slightly decreased. In normal operations, it is emphasized that attention should be paid to the maintenance of the equipment. The intention is to extend the operating life of the equipment so that its operating functions and production power can maintain normal conditions for a long period of time. To ensure the steady growth of the economic benefits of the enterprise.
The manufacturer of Screw and Barrel for Extruder tells you that the maintenance of the extruder is divided into daily maintenance and regular maintenance. The daily maintenance of the extruder is the operating procedure rules and operating precautions in the production operation of the extruder, which requires the operator to implement it carefully. (Note here: the operator should do it according to the working principle of the extruder screw)
The manufacturer of Screw and Barrel for Extruder tells you that regular maintenance of the extruder can be organized according to the load and operating time of the extruder. Generally, it can be carried out once every six months or once a year. The manufacturer of Screw and Barrel for Extruder tells you that the repair fitter and the equipment operator work together during maintenance. The work content is as follows:
①Clean and wipe the oil stains on the extruder and the dust in the electric control box.
②The manufacturer of Screw and Barrel for Extruder tells you to disassemble the gear transmission reducer and the bearing gland to check the wear and tear of each transmission part; observe the quality change of the lubricating oil and make up for the amount of oil in time; if the oil contains more sundries, Should be filtered or replaced.
③The worn gears should be surveyed, and the bearing specifications should be recorded. After the operation, a spare parts production or purchase plan should be proposed, and time for repair and replacement should be arranged.
④Check the V-belt wear status and adjust the center distance of the V-belt equipment (it is required to keep the V-belt transmission operation loose and appropriate); if the V-belt is severely worn, it should be replaced.
⑤The Screw and Barrel for Extruder manufacturer tells you to check the wear and tear of the barrel and screw. There are slight scratches and friction marks on the inner surface of the barrel and the outer circle of the screw thread. It can be polished with fine oil stone or fine emery cloth to achieve a smooth lubrication. Record the working surface of the barrel and screw (the inner circle of the barrel and the outer diameter of the screw) Measured scale.
⑥Screw and Barrel for Extruder manufacturer tells you to detect and calibrate the actual heating temperature of the barrel (measured with a mercury thermometer) and the temperature error value of the appearance to ensure the correct control of the operating process temperature of the extruder
⑦Adjust and test each safety alarm equipment to ensure the reliability and accuracy of its operations.
⑧ Check and test whether various infusion pipelines (water, gas and lubricating oil) are smooth, and repair and dredge the leaking and blocked parts.
⑨ Check and experiment whether the connection of each power transmission line is strong, and whether the safety grounding protection of the electric control box and equipment is strong.
⑩Screw and Barrel for Extruder manufacturer tells you to check whether the working orientation of the experimental heating equipment, cooling fan and safety cover is correct, and make necessary adjustments and corrections to ensure that the extrusion screw can operate correctly and effectively.
