Conical Twin Screw and Barrel maintenance work content
Conical Twin Screw and Barrel is in the process of non-stop operation, its internal parts inevitably wear out, which directly leads to a decrease in production efficiency. In response to this unfavorable phenomenon, related industries have proposed to maintain the Conical Twin Screw and Barrel accordingly. So what are the maintenance tasks of Conical Twin Screw and Barrel? Let's take a look together next!
After the Conical Twin Screw and Barrel was put into production, due to the long-term dynamic load operation, coupled with the corrosion of corrosive gas and molten material, some transmission parts and Conical Twin Screw and Barrel
The operation function and production power of the machine will gradually change and slightly decrease. 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 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 follow the working principle of Conical Twin Screw and Barrel)
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 a year. During maintenance, repair fitters and equipment operators cooperate with each other. The work content is as follows:
①Clean and wipe the oil stains on the extruder and the dust in the electric control box.
② Disassemble the gear transmission reduction box and the bearing gland to check the operating wear status of each transmission part; observe the quality of the lubricating oil and make up for the amount of oil in time; if the oil contains more debris, it 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.
⑤ Check the wear condition 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 flat lubrication. Record the working surface of the barrel and screw (the diameter of the inner circle of the barrel and the outer circle of the screw) Measured scale.
⑥ Detect and verify the actual heating temperature of the barrel (measured with a mercury thermometer) and the apparent temperature error value 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.
⑩Check and test whether the working position of heating equipment, cooling fan and safety cover is correct, and make necessary adjustments and corrections to ensure that Conical Twin Screw and Barrel can operate correctly and effectively.
