Common wear faults of Roots blower components:

        During normal service, its wear and tear is negligible. The gear of Roots blower can usually accommodate reasonable tooth wear. When the high oil level in the gearbox will cause agitation and excessive oil heating, it indicates that the temperature at the bottom of the oil tank is abnormally high. If you continue to operate under this condition, the gear will heat up and the gear may be affected by rapid wear, which will cause the impeller blade to contact or the unit to seize.

The service life of Roots blower booster is closely related to the bearing. Gradual wear may change the position of the shaft until friction occurs between the impeller and the cylinder block or top plate. Sudden bearing failure usually has serious consequences. Since the impeller shaft assembly is no longer supported and correctly positioned, large-scale damage to the sleeve and gear may occur immediately after bearing failure.

The drive shaft seal assembly is composed of two independent lip seals immersed in oil and located in the drive end cover. If the oil level of the sight gauge rises, it indicates that the oil leakage through the inner side member is excessive, and it should be replaced as an assembly. Unless the seal or its bearing surface is damaged, the possibility of leakage through the outer member is small. In addition, the smoothness of the shaft also has a considerable impact on the performance of this type of seal. Operation problems may be caused by reasons other than component damage. Since the clearance is only a few thousandths of an inch, any change in installation or pipe support may cause interference and friction.
