冷轧厂液压系统密封问题改进措施

Seal Actuality and Amelioration for Hydraulic System

冷轧厂的液压系统要求运行精度高,且运行压力高,动作频繁。但在设备连续运转一段时间后,液压系统密封元件老化加速,粉尘及磨屑进入系统,对系统形成污染,加速了缸体的磨损,缸体运行产生压力波动,影响正常轧钢。采用进口的特种密封材料,利用高精度的加工方式,改变关键部位的密封结构,解决了液压系统污染及其一系列问题。

Hydraulic system of cold rolling plant runs in high precision, at high pressure, and moves frequently After hydraulic system starts one period, seal property turns to get worse, dust and grinders is likely to invade hydraulic circuit, forming badly contamination, accelerating cylinder abrasion, making working pressure waves serious, to influence normal rolling. To adopt foreign special seal material, use high exact machining process, improve seal structure of important part, could solve a series of hydraulic seal contamination and the other problems.
