Two Important Questions

摘要

"Using the vendor's recommendation" is the typical path we take to determine what PM/ECCM tasks we need to do for machine components. The problem is that they often don't have recommendations and, if they do, they are typically not very good. As a simple example, try to find the inspection recommendation for your mill's rotary joints for dryers (not checking the whole system, just the rotary joint.) Go ahead... I'll wait while you look... Oh, you are back! What did you find? If you found the manual at all, it probably tells you to look at the sight glass for flow and check for leaks at connections, right? This means that the recommendation is to wait for the steam joint to fail (leak) before you replace it, or parts of it.
