摘要
任何机械生产系统都会因与磨损相关的故障等而导致必要的维修,从而降低其生产率。机器组件,如轴承出现故障,则必须停机至机器修复,因此必将影响生产进度。这些无法预料的停机可能造成不能如期完成生产,此外,停工也会给生产厂家带来损失。如果未持续监控机器组件,则其失效通常都不可预知。维修机器所需的时间通常比更换坏组件花费的时间更多。这也是安装状态监测系统的价值所在,状态监则系统能够自动监测组件的状态并预估可能发生的故障。该系统在纺织生产上非常有用,因为纺织品是在高速条件下生产的,即时维修的理念旨在尽可能多地减少因机器维修造成的耽搁,生产过程中很小的耽搁都会对利润产生巨大的影响。
The productivity of any mechanical production system is decreased by necessary repairs caused by e.g. wear-related failures. Because the machine has to stop in case a machine component such as a bearing fails, production slows down until the machine has been repaired. The deadlines for the production will be at risk because of the unexpected stop. In addition the down-time results in a loss for the company. The failure of machine parts is mostly unpredicatable if the part is not continually monitored. The time needed until the machine is repaired is usually longer than the actual time needed to replace the broken component. This is the motivation to install condition monitoring systems, which automatically track the condition of the components and predict a possible failure. This system is especially useful for textile production, because the product is created at high speeds, in consequence, a small delay in production has a significant impact on the profit. The concept of just-in-time-maintenance is aimed at preventing the maintenance-related delays as much as possible.
