How to deal with the damaged bearings of the automatic mixer? The early damage of the sliding bearing of the automatic mixer is much more common than the bearing burning, so it is important to prevent the early damage of the sliding bearing. The following sections will explain more details for you.
The correct maintenance of sliding bearing is an effective way to reduce the early damage of bearing, and also a reliable guarantee to extend the service life of bearing. Therefore, in the daily maintenance and repair of the engine, attention must be paid to the appearance of the alloy surface, back, end and edge corners of the bearing,
In case of any abnormality or signs of more than half wear, it is necessary to carefully find out the causes, take corresponding measures, improve the working conditions of bearings, and pay attention to the prevention of early damage of sliding bearings.
Under the repeated action of the cylinder pressure impact load, the surface layer of the sliding bearing undergoes plastic deformation and cold work hardening, loses the deformation ability locally, gradually forms stripes and continues to expand, and then forms cavities on the loaded surface layer as the wear debris falls off. In general, when cavitation occurs on the bearing bush, the pit appears first.
Then the pits gradually expand and cause the alloy layer interface to crack, and the cracks extend along the parallel direction of the interface until peeling off.
The main reason for cavitation of sliding bearing is that the sudden change of cross section of structural elements such as oil groove and oil hole causes a strong disorder of oil flow, forming bubbles in the vacuum area where the oil flow is disordered, and then cavitation occurs due to bubble collapse due to pressure rise.
How to deal with the damaged bearings of the automatic mixer? The above is the relevant answer to the question, so you are required to check and maintain the fixed parts more frequently in daily use, so it is not a problem to extend their service life. Follow us , learn more!
