MDS - Machine Deflection Shapes - Adash - #2

Text version of the page

The only one difference between normal vibration measurement and machine deflection shapes measurement is the need to measure more points on the machine. The use of the MDS method is not limited to experts. It is one way to evaluate data, which can be used by everybody with a basic knowledge of vibration measurement. Adash Limited organises special courses connected with MDS measurement. There are demonstrations and all questions and aspects of MDS method are explained. MDS is a very sensitive tool for many types of machine failure which generate vibration in low and middle frequency bands. MDS measurement does not operate in bearing failures (high frequency). All common failures as imbalance, looseness, misalignment or a resonant problem can be indicated by MDS measurement. The model shows a motor and a gearbox of a conveyer belt. Loosened connection of the base girders with supports of the machine can bee detected by using MDS. A pedestal of a mill fan in a power station block. Looseness in the bearing stand is evident after using MDS. Trajectory of shaft vibration of turbine and generator in hydro-power station. The geometrical model of a primary ventilator in a CHP station block displays an electric drive, two bearing housings and a fan section above the metal pedestal. The measurement disclosed incorrect fastening of the whole machine pedestal into the building floor.
