Vibration of high-speed centrifuge where to start

Vibration of high-speed centrifuge where to start

Often we will use centrifuge his oscillation region centrifuge function is. If we want to say that we can use the forced vibration damping or automatic damping. He is the former of shock absorber for a variety of methods to give him across the frame and the oscillating separation, the latter is the centrifuge speed to avoid critical speed in the design of the time. High speed centrifuge spindle bearing seat for him into flexible vibration form, stop using the flexible when linking the spindle and motor. Rubber shock absorber he generally can reach the need of high-speed centrifuge damping. Rubber hardness is relatively large, and the critical speed of the system of his is very high, if the damper hardness is too low that his strength was not up to our needs, and he is also very easy to bad. In the laboratory of high speed centrifugal machine shaft he is two, he is a relatively long, itself is very flexible, but also can automatically to stop scheduling, another of his rough comparison is also very short, winding deflection itself will be smaller, but his work speed critical speed to be higher than. Even if is a flexible system of the same, but his slender flexible shaft stiffness will be larger, his is the use of shaft turns to stop on the rigid, this will be a bit more.
