Fluid induced instability is due to the shear force generated by the fluid flow due to, as long as this reduces the tangential force, no doubt will greatly enhance the stability of the system.

Use tilting pad bearings can achieve this goal, because tilting pad bearings have many branches live tiles, each tile can form a wedge, without considering tile inertia and friction pivot, then each tile produces The film can always force through its center pivot and the journal, which always kept the external load intersect at one point, so it does not produce a journal for the whirl movement pushing force.

Improve initial steady speed limit aims to make the rotor Stainless steel tanks in a stable speed, thereby preventing the occurrence of vortex motion and vibration. The initial steady speed limit and the average rate is inversely proportional to the fluid, seven water ferrous sulfate and proportional to the radial stiffness of the system, therefore, to improve the initial steady speed limit, it is necessary to reduce the average rate of the fluid, increasing the diameter of the system stiffness.

Also, it can reduce the average fluid velocity:

(L) the use of anti-interference scroll technology circumferential fluid movement. For example, into the oil can be reversed to the way in design, and other open axial grooves on the bush. Instability phenomenon occurs when oil whirl and vibration timely open Jacking oil pump method occurs in the actual operation of the temporary processing unit has received very good results.

(2) by changing the geometry of the bearing to interfere with the flow of the surrounding fluid. It may be non-cylindrical tile (oval watts) and live tile support bearings (tilting pad), in this type of bearing, cylindrical bearing much weaker than fluid circulation.
