What is the content of mechanical fault diagnosis?
1.The Monitoring of Machine Operating Conditions
According to the information generated at the operation of machinery and equipment to determine whether the equipment is operating normally, its purpose is to find signs of equipment failure earlier.
2.Trend forecasting of equipment operation status
Based on the condition monitoring, the development trend of equipment operation status is further predicted in order to predict the speed of equipment deterioration in preparation for production scheduling and maintenance plan in advance.
3.Determination of the fault type,extent,location and cause
The most important is to determine the type of fault, which is based on the condition monitoring, when the machine is confirmed to be in an abnormal state need to be further resolved, the purpose is Provide the basis for the final diagnosis and decision.
The Universal Method to Diagnose Mechanial Fault
Mechanical equipment in motion (including normal and abnormal conditions) will produce vibration and noise. Further research also shows that the vibration and noise strength and its main frequency components and the type of fault, extent, location and causes are closely linked. Most machinery and equipment are fixed-speed operation of equipment, the laws of the movement of various components determines its vibration frequency. Because it is a constant speed operation, the vibration frequency is the characteristic frequency of the part, and the change of the vibration amplitude of the observed characteristic frequency can know the movement state and the degree of deterioration of the part.
Test and Analysis System(hardware and software) Used in Mechanical Fault Diagnosis
A good and practical data test and analysis system really plays an important role in diagnosing mechanical fault.So you should choose the best monitoring instruments and reliable data analyzers to assure a cost-effective measurement solution.
