Why is there severe vibration when the centrifuge reaches 400 revolutions during shutdown?
Thread Content
The company has a centrifuge that was imported; most of the time, when its speed drops to 400 revolutions per minute, it starts vibrating violently for about 50 seconds. However, sometimes it stops without any sound at all. Numerous analyses have been carried out, but the cause has not been identified. I earnestly ask all the experts to take a look
Maybe the 400 revolutions per minute frequency is resonating with those components above: lol
All operating equipment has a resonance zone, and during design, common operating speeds are usually avoided, with rapid movement away from this resonance zone when accelerating or decelerating.
