失效分析

FAILURE ANALYSIS

密封失效分析 — 发现泄漏的根源

Seal Failure Analysis — Finding the Root Cause of Leakage

90%+

液压系统故障由密封失效引起

of hydraulic system failures are caused by seal failure

密封费用仅占总检修费用的1~3%，却直接影响超过90%的液压系统故障。不要仅仅更换密封件，更重要的是分析失效原因，了解密封件及其工作的系统，才能找到防止泄漏的根本方法。

Seal costs account for only 1~3% of total maintenance cost, yet directly affect over 90% of hydraulic system failures. Don't just replace seals — analyze failure causes, understand the seal and its system to find the root-cause solution to leakage.

维修模式

MAINTENANCE MODES

延长检修周期 — 所有工厂的检修趋势

Extending Maintenance Cycles — The Way Forward

工厂中存在以下三种维修模式。被动式维修代价最高，预防式维修容易过度更换，而周期性检修兼顾可靠性与经济性，是延长检修周期的发展趋势。

Three maintenance modes exist in factories. Reactive maintenance is the most costly, preventive maintenance tends to over-replace, while periodic inspection balances reliability and economy — the trend for extending maintenance cycles.
