The treatment methods for oil throwing of thrust bearings mainly include the following aspects:

1. Replace seals:

One of the main reasons for oil throwing of thrust bearings is the aging, wear or damage of seals, which causes lubricating oil to leak directly from between seals.

Therefore, replacing seals is a common way to solve the oil throwing problem. During the replacement process, it is necessary to carefully check the matching degree between the seal and the shaft to ensure good sealing effect.

2. Adjust the oil level of lubricating oil:

The oil level of lubricating oil is also one of the factors affecting oil throwing of thrust bearings.

If the lubricating oil is too little, it may cause insufficient lubrication of the bearing, resulting in overheating and oil throwing. Therefore, it is necessary to adjust the oil level of lubricating oil according to the requirements of the equipment to ensure sufficient lubricating oil.

3. Use the blocking method:

Adding fan blades to the inner wall of the thrust head or adding oil retaining rings to the inner wall of the rotating part can increase the blocking effect on the oil and reduce the oil throwing phenomenon.

For external oil throwing, measures can be taken to enhance the sealing performance, such as setting a labyrinth groove between the rotating part and the cover plate and adding multiple layers of sealing rings.

4. Use the equalizing pressure method:

Direct the airflow in the high-pressure area of the rotor to the lower part of the oil retaining pipe to balance the upper and lower pressures, which helps reduce the phenomenon of external oil throwing.

By setting a breathing hole on the thrust oil tank cover, the internal and external pressures can be balanced, further reducing oil throwing.

To deal with the problem of thrust bearing oil throwing, it is necessary to start from multiple aspects, including replacing seals, adjusting the lubricating oil level, using the blocking method and equalizing pressure method, etc. During the operation, careful inspection and adjustment are required to ensure good treatment effect.
