近十年,液压机械设备愈来愈多地运用于冶金行业。与传统的机械设备不同,液压设备一旦出现故障,就容易引起整机失控,而且故障多半具有突发性。液压元件摩擦时的工作间隙小,摩擦面大,摩擦强度高。相对运动造成的异常磨损往往是逐渐发展,恶化到某一程度时突然发生故障。定期取油样进行铁谱 In the past ten years, more and more hydraulic machinery and equipment were used in the metallurgical industry. Different from the traditional mechanical equipment, hydraulic equipment in the event of failure, it is easy to cause the machine out of control, and the failure of most of the sudden. Hydraulic components when the friction small work space, large friction surface, high friction. Abnormal wear and tear caused by relative movement tend to gradually develop, suddenly deteriorating to a certain extent. Regular oil samples for iron spectrum
