Maintenance of the Calender

Edit: John 2020-03-17 Mobile

  After a long period of production, the machine will wear out. There is no fixed machine. Only good maintenance can make the machine and equipment permanent, and always produce superior products.

  The roller bearings of modern PVC calenders are automatically lubricated with lubricating oil. It has the advantages of sufficient lubrication and short running-in time after maintenance (bearing replacement). However, this type of lubrication requires high oil seals, otherwise it is easy to leak oil. The calender works under the condition of low speed and high load. The choice of lubricating oil should be based on the different requirements of the use of high viscosity oil products. When the circulating oil quantity of the lubricating oil is insufficient or the circulating oil is broken, an alarm device should be provided in the circulating oil pipeline system.

  The requirements for the performance of PVC calendering oil are mainly high-temperature and impact-resistant heavy loads. Especially for gears and bearings of rolling equipment, a solid oil film is required. Since PVC calendering oil is easily mixed with water during use, it is required to have good Water separability.
