液压系统造成污染的原因是多方面的,在液压系统和元件的加工、装配、包装、储藏、运输过程中都可造成系统油液污染。在现代化的热连轧机设备中,由于高速化、连续化、高效率、高精度生产工艺的要求,液压系统的工作条件要比一般系统恶劣得多,所以必须有可靠的过滤措施,才能保证液压系统正常运行。轧机液压系流除了系统本身造成的污染外,绝大部分是由外部恶劣的工作环境所致。如热轧线有大量的高压除磷水、冷却水、氧化磷屑、侵蚀工作在带钢通过附近的液压缸、软
Hydraulic system causes pollution in many ways, in the hydraulic system and components processing, assembly, packaging, storage, transportation system can cause oil pollution. In the modern hot strip mill equipment, due to the requirements of high speed, continuous, high efficiency and high precision production process, the working conditions of the hydraulic system are much worse than those of the ordinary system. Therefore, reliable filtration measures must be taken to ensure that the hydraulic pressure The system is operating normally. Mill hydraulic system flow in addition to the system itself caused by pollution, the vast majority of work by the external environment. Such as hot-rolled line has a lot of high-pressure phosphorus water, cooling water, phosphorus oxide, erosion work in the vicinity of the strip through the hydraulic cylinder, soft
