Centrifuge Mechanical Vibration and Dynamic Balance

Unbalance is one of the typical failures of rotating machinery. According to statistics, about 35% of rotating machinery failure is caused by imbalance.

A. Causes for mechanical vibration of the centrifuge

The mass of the centrifuge drum and spiral rotating body is uneven in circumferential direction, forming a certain eccentricity. When rotating, an unbalanced centrifugal inertial force is generated, and mechanical vibration is caused.

(1) Uneven material

(2) Bland defects

(3) Asymmetric geometry of spiral blades

(4) Manufacturing error

B. Centrifugal rotating body dynamic balance

We have horizontal balancing machine that can balance the spiral rotating body of centrifuges. We have a wealth of experience in the centrifuge industry, we can provice you a suitable balancing machine for your use.

C. Balance Correcting Method for spiral rotating body

(1) Add weight: welding, tin soldering, riveting, add screw, add weighting block

(2) Remove weight: boring, drilling, chiseling, milling, grinding

(2) Adjust the mass of correction:

Adjusting the size and orientation of the correction mass in the pre-designed adjustment structure on the spiral rotating body to achieve the above-mentioned add weight and remove weight
