  • 摘要：Hydraulic oil in a vulcanizing machine has the effect of power transmission, cooling hydraulic components, anti-corrosion and rust-proof, etc. So whether the operation of hydraulic system is reliable and accurate, depends on not only the hydraulic components including the material, performance and reasonable design, but also the selection of hydraulic oil. Hydraulic oil will deteriorate under high pressure, high temperature long-term use, which may lead to corrosion and wear of hydraulic components, making the hydraulic system not working properly, and then causing accident. Conversely, if the hydraulic oil is changed too frequent, it will result in energy waste. How to grasp the hydraulic oil quality and replace hydraulic oil timely is important to protect the equipment and reduce cost. Therefore, understanding the development situation of hydraulic oil, better industrial production management and the application of hydraulic oil is meaningful.%液压油在硫化机上具有传递动力、冷却液压元件、防腐、防锈等作用.所以硫化机液压系统运转是否可靠、是否准确,不仅仅取决于液压元件的材料、性能、设计的是否合理,很大程度还取决于液压油的选用.液压油在高压、高温下长期使用会老化变质,而变质的液压油又会导致液压元件腐蚀和磨损,造成液压系统工作不正常,继而导致重大事故发生.反之,若液压油更换过早、过频,因停工、停机换油,会造成能源浪费.如何掌握液压油的质量状况,及时准确地更换液压油,是保护设备、降低成本的重要手段.因此,了解液压油的发展状况,在工业生产中更好地管理与使用液压油是一项有实际意义的工作.
