Equipment status analysis
Thread Content
Dear colleagues: The company now requires equipment condition analysis, but I’m not sure how to proceed. Does anyone have any ideas or templates in this area that they could share with me? Thank you,
The common device statuses are: running, under maintenance, and standby； Typically, it is devices that are in operation but exhibit signs of potential failures that need to be analyzed
There are many methods for condition analysis, such as ultrasonic analysis, vibration spectrum analysis, lubricant analysis, etc. Vibration analysis is currently widely used and is quite reliable. The general approach is: 1. Establish a vibration database for all the equipment in the plant ； 2. Establish maintenance standards for each piece of equipment; for example, if the amplitude velocity exceeds 7.6 mm/s, the equipment must be shut down for maintenance ； 3. At regular intervals, such as every two months or one month, conduct vibration tests at the same location using the same vibration tester ； 4. Upload vibration data to the database ； 5. Conduct a vibration trend analysis to predict the remaining time before shutdown for maintenance. That’s roughly the idea; in reality, the work is more complex. You need to study the failure models of the equipment, carry out targeted monitoring, and take into account the material procurement cycle as well. When used properly, it can indeed save a lot of money, but it seems there aren’t many options available in China that work well.
