    Abstract:

    擠出機的保養和維護的操作內容是擠出機生產操作中的操作程序規則和操作注意事項,操作人員必須仔細執行。 根據擠出機的負載和工作時間,可以定期維護擠出機。通常,它可以每六

    The operation content of extruder maintenance is the operation procedure rules and operation precautions in the production operation of extruder, which must be carried out carefully by the operator.
     
     
     
    According to the load and working time of the extruder, the extruder can be maintained regularly. It can usually be performed once a year or six months. After maintenance, repair fitter and equipment operator will work together. The work is as follows.
     
     
     
    1 clean and scrub the oil on all parts of the extruder and the dust in the electric control box.
     
     
     
    2 remove the gear reducer and bearing gland, check the wear of each transmission part; observe the change of lubricating oil quality, and replenish the oil in time; if the oil contains more impurities, it should be filtered or replaced.
     
     
     
    3. The worn gear shall be drawn and the bearing shall be marked with standard. After the operation, the spare parts production or procurement plan should be put forward, and the organization should be repaired and replaced at any time.
     
     
     
    4 check the wear condition of V-belt and adjust the basic distance of V-belt equipment (it is very important and appropriate to keep the operation of V-belt driver); if the V-belt is seriously worn, it should be replaced.
     
     
     
    5 check the wear of the screw tube. There are slight scratches and friction marks on the inner and outer surfaces of the barrel and on the outer thread of the thread. It can be smoothed with fine oilstone or fine emery cloth to achieve the purpose of smoothness and smoothness, and the working surface of barrel and screw (inner diameter of barrel and outer diameter of screw) can be recorded. Measurement scale.
     
     
     
    6 test and verify the actual temperature of barrel heater (measured by mercury thermometer) and the temperature error value of the instrument to ensure accurate control of the working temperature of extruder.
     
     
     
    7 adjust and test each safety alarm device to ensure the reliability and accuracy of its operation.
     
     
     
    8. Check and test whether various infusion pipelines (water, gas and lubricating oil) are not clear, and repair and dredge the leaking and blocked parts.
     
     
     
    9 check and test whether the connection of each transmission line is firm, and whether the safe grounding maintenance of electric control box and equipment is firm.
     
     
     
    During the inspection, the working direction of the experimental heating equipment, cooling fan and safety cover is incorrect. Please make necessary adjustment and correction to ensure that they can work accurately and effectively.
