What is the acceptable range for the vibration value of the main bearing in the TRH074 centrifugal dryer, measured in terms of vibration velocity? The unit is mm/s. Ba Industrial specifies that the displacement should not exceed 80μm; what is the equivalent value for vibration velocity in mm/s? Can it be converted?

Such centrifuges have high vibration requirements; vibration meters can measure amplitude, vibration intensity, and vibration acceleration all at once. For these types of centrifuges, we ensure that the vibration level when they leave the factory is within 2–3 mm/s, with the amplitude kept below 4 microns, that is, 40 micrometers
Peak displacement: in micrometers, i.e., um – the maximum distance of vibration in both positive and negative directions, indicating issues such as shaking or insufficient stiffness of the equipment. Effective velocity: expressed in millimeters per second, i.e., mm/s. The effective value of the vibration velocity is the root mean square value of the vibration velocity, denoted as RMS; it directly reflects the energy of the equipment’s vibrations. The maximum of the effective values of the speeds measured at different locations on a device is referred to as the vibration intensity of that device. The seismic magnitude uses the effective value of the vibration velocity. Regardless of the speed of the equipment or its power level, the operating condition of the equipment can be assessed using the effective value of the vibration velocity of the equipment. Acceleration peak value: in meters per second squared, m/s²; it represents the shock signals generated by equipment. This value is often used to assess the condition of rolling bearings and gears, as well as any rubbing between equipment components. It can also indicate shocks caused by fluids (against the housing or impellers), jets, or cavitation. There is no process of conversion among the three; they simply reflect different aspects of the issue.
The vibration level of the equipment should normally be kept below 4.5. What’s the situation with the other equipment in your factory?
