Effect of grease on vibration of slurry pump bearings

The vibration of the slurry pump bearing is transmitted through the air and manifests itself in the form of noise. The noise is often caused by excessive bearing vibration. Bearing companies generally use the method of measuring vibration values to evaluate the vibration and noise of the bearing. To reduce the vibration of motor bearings, in addition to the design, material and manufacturing process of the bearing, the selection of grease is also an important factor. What is the impact of grease on the vibration value of the bearing?
1. The influence of grease viscosity on bearing vibration value. For the same type of grease, the vibration level of the bearing generally decreases as the viscosity of the grease base oil increases. Among soap-based greases, greases with a lighter consistency are less noisy than greases with a thicker consistency.
2. Influence of the particle size of grease aggregates. In the case of grease in general, as the length and width of the fibers increase, the vibration level of the grease increases accordingly. The particle size is small and evenly dispersed, and the fluctuation range of the bearing vibration value is also small. The aggregates and reactants have large particle size and uneven dispersion, which will affect the vibration level and stability of the grease, and the vibration value fluctuation range is large.
