在工程机械使用过程中,为确保其有良好的技术状况和较长的使用期限,要对工程机械进行定期的维护与保养,以保证工程机械具有良好的工作性能。对提高企业经济效益和工程机械使用效率是至关重要的。 一、良好的维护保养有利于降低故障率和提高可靠性 工程机械在整个使用期间其技术状态始终处在变化的过程中,其使用故障按性质分为突发性与渐发性两种。突发性故障是偶然的,随机的,与机械使用时间无关,其故障间隔时间按指数分布。渐发性故障
In the process of using construction machinery, in order to ensure that it has a good technical condition and a long service life, the construction machinery should be regularly maintained and maintained to ensure that the construction machinery has good working performance. To improve the economic efficiency of enterprises and the efficiency of construction machinery is essential. First, a good maintenance helps to reduce the failure rate and improve reliability Construction machinery throughout the use of its technical status is always in the process of change, the use of fault by nature is divided into two kinds of sudden and gradually. Sudden failure is accidental, random, and has nothing to do with the use of mechanical time, the breakdown interval of time by the index distribution. Progressive failure
