Parts of the fracture high magnification scanning electron microscope, the following characteristics are found:
① magnification observation shows that there were many fan-shaped pattern of micro-topography.
② arc of fatigue crack front and there is a lot of corrosion pits.
Sampling and analysis of lubricant, through which the contamination level is a mixed metal powder or other foreign matter judgment. Method can not be observed close to a large rolling bearing or bearing is particularly effective.
To determine the need to improve the experience. Must have sufficient training to identify bearing and non-load-bearing voices sound. Therefore, we should try to carry out this work by the hand. With listening, or listen to a stick attached to the shell, you can clearly hear the sound of rolling bearings.
In order to improve the machine's operating rate, reduce unplanned downtime and improve the economic benefits of paper mills, due to the use of ordinary wear and tear rolling paper machine lubricants cause poor lubrication failure, can be used for micro-polished, high-performance synthetic lubricants function Line Repair . Mill, in order to avoid unplanned downtime, resulting in huge economic losses, save on maintenance costs and spare parts costs.
