Roots FansIn the process of using the bearings appeared to heat up, so what are the reasons that lead to the heat of the Roots fan? On this issue Roots fan small editor to take you to understand.
Reason: 1, lubrication system failure, oil is not clean, viscosity is too large or too small
2、The oil ring on the shaft does not rotate or rotates slower, bringing no oil to the
3、Skewed shafts and bearings, blower shafts and motor shafts are not concentric
4、Bad quality of research and scraping of shaft tile, contact arc is too small or poor contact
5、Cracks, abrasions, abrasions, slag and other defects on the surface of the axial tile
6, Shaft tile end face and thrust flat washer clearance is too small
7. Bearing gland is pressed too tightly and there is no clearance in the bearing.
8、Damaged rolling bearings, broken ball supports
Treatment: 1, overhaul the lubrication system or replace the lubricant
2. Repair or replacement
3、Centering to make the two axes concentric
4、Research and scrape the shaft tile
5. Repair or recast tile liners
6. Adjustment of clearance
7. Adjust bearing gland pads
8、Replacement of rolling bearings
