BISOPE series 12- Diseases of equipment (rotating machinery), (abnormal state identified through equipment diagnosis and vibration analysis)

--------------------------------------------------------------------------------------------------------------------------------------

When a machine reciprocates or rotates, vibration is necessarily generated, but even if it is a natural conversion of energy, if the vibration is high, you can intuit that the condition is bad. If the machine is damaged due to high vibration, it can cause damage to human safety and property. It will help you understand the different rules of diagnosis. If the machine correctly matches the name of the sick disease, this becomes the diagnosis result of the facility analyst.

 

Vibration detects machine failures. Type of disease name (defect cause)

 

An abnormal state of a machine that can be detected by vibration is called a 'fault', and this type of fault can be viewed as the type of machine disease. Like a human comprehensive examination, machines can also perform blood tests (lubrication tests), X-rays, and ultrasound tests, but here, we know and briefly explain the types of defects that can be confirmed by 'vibration', which can most often infer the name of the disease. decide to do

First of all, the first thing that should be premised is that it should be a diagnosis analyzed with the result of well-measured (sensor, installation, measurement setting, direction, unit selection, etc.). In addition, you must have experience in diagnosing various vibration sources and facilities, and the experience of the operator who has operated and repaired the facility the most must be included. Therefore, overall, as many defects as possibleachine that was imitated without additional design improvement.
