Discussion on device status detection methods
Thread Content
Today I attended a lecture on methods for monitoring equipment status. I’d like to share a piece of experience: \"If the rate of change in equipment vibration is 25% of its current value, it’s necessary to pay attention to the equipment’s operating condition.\" Also, does anyone know of any good books on condition monitoring that are both practical and highly professional? Please recommend them! Thank you!
Generally, it relies on personal diagnosis, with the main methods being listening, observing, touching, smelling, and comparing. Some companies (mostly foreign-owned ones) are more advanced and use specialized equipment for testing.
We use portable vibration meters for monitoring here, and generate curves with EXL
In the workshop, operators use the five methods of \"listening, observing, touching, smelling, and comparing\"; technicians employ simple fault diagnostic tools to identify issues with equipment, while professionals from the mechanical department use advanced fault diagnosis systems to conduct thorough inspections of rotating equipment.
There are many books on fault diagnosis. I recommend the book on equipment vibration fault diagnosis by Jiaotong University
I recommend the book \"Equipment Condition Monitoring and Fault Diagnosis Techniques and Applications\", published by the Industrial Equipment and Information Engineering Publishing Center of the Chemical Industry Press. It covers topics such as concepts, classification and description of signals, data acquisition and digital signal processing, state characteristic parameters and testing of rotating machinery, fault diagnosis of gear mechanisms, fault handling and diagnosis techniques for rolling bearings, infrared technology, and the principles of expert systems for equipment fault diagnosis; it’s a pretty good book.
