摘要
液压系统是工程机械的重要核心组成部分,工作中的故障具有复杂性、多样性及隐蔽性。操作者应掌握液压系统的结构原理及故障诊断技巧,做好日常的维护保养工作。液压系统的故障诊断主要有观察诊断法、逻辑诊断法等。观察诊断最为常用和实用,重点是防微杜防渐,小问题及时处理;对于复杂的液压系统,可采用逻辑分析推理。
The essence component of engineering machinery is the hydraulic system.The characteristics of working faults include complexity,diversity and crypticity.The operators should grasp the structure principles and fault diagnosis techniques of hydraulic system and do well daily maintenance.Fault diagnosis methods of hydraulic system mainly include observation and logical diagnosis and so on.The former is most common and practical,which can solve trivial problems in time.While the later method can be used when it comes to complicated hydraulic system.
