Why MFS-MG
The Best Tool Available for Learning Machinery Diagnosis
To gain an in-depth understanding of different vibration signatures, controlled experiments on a device that emulates real world machinery are needed. While analysis of a single machinery fault may be beneficial, there are many occasions when the analysis of the interaction between dynamic stiffness, resonance, and speed is essential in order to gain an understanding of real world vibration spectra. With the MFS-MG, the expertise required to diagnose industrial machinery problems in well controlled experiments can be developed and enhanced. With a plant running at full production, it is virtually impractical to gain an understanding of the kinetics and dynamics of machinery without adversely affecting production and profits: The MFS-MG enables offline training and experimentation which in turn will minimize production downtime.
Designed to Study Oil Whirl And Whip In Fluid Film Bearing
The MFS-MG fitted with a resonance kit is the perfect tool to gain practical experience in rotating machinery resonance and to learn resonance mitigation methods. With a different number of rotor disks installed at various locations on the main shaft, resonances up to the third mode can be excited. The bode plot of the main shaft vibration during a coast down test is illustrated in the right figure. Three resonances can be identified clearly. Oil whirl and whip are important instability phenomena associated with rotors supported fluid film bearings. With proper selection of the bearing load (the number of rotor disk), bearing clearance (the selection of bearing cartridge) and oil pressure (adjusting the oil supply valve), the oil whirl and whip can be simulated using the MFS-MG. The waterfall plot on the right illustrates the oil whirl and whip observed on this simulator. The first critical speed of the main shaft (1X), oil whirl and oil whip are all identified in this waterfall plot. In order to observe oil whirl and whip, the simulator must be running at more than twice of the first critical speed of the main rotor shaft.
