This post was finally edited by CHANGBAISHI on 2022-4-23 06:54 with some insights from amateur copycats for reference. From the picture, it seems that this phenomenon is indeed related to frequent startup. But there are still some issues worth noting,,,,,. For example, whether the startup process complies with the requirements of the operating procedures. Whether the oil has passed the analysis and inspection after being used for a long time, whether the oil tank is cleaned and wiped during maintenance, and what is the cleaning method? In terms of bearing wear, check whether there is sludge produced by carbon deposits in the oil, and whether there are asbestos rubber gaskets in the static seal gaskets. Also, is the wear of the thrust shoe related to the levelness of the unit? As for the damage point of the impeller, it is not closely related to the bearing. Pay attention to whether the impeller is scaled and needs to be cleaned. This aspect has a greater bearing on the dynamic balance of the rotor. To see the wear of the thrust surface, attention should be paid to the levelness of the detection shaft or the levelness of the machine body. Furthermore, this kind of damage to the tile surface is called "grinding" the tile, which seems to be appropriate, meaning grinding. For reference.
