Plate heat exchangers are widely used in many industrial applications because of their efficient heat exchange capacity and compact structure. However, in some cases, the micro-deformation characteristics of plate heat exchangers can cause pressure fluctuations in the lubricating oil system. Here is a detailed analysis

As a key component of rolling bearing, steel ball plays the role of carrying and transferring load and movement in bearing, and has an important impact on bearing life and vibration noise. The steel ball is subjected to periodic variable loads on the whole surface, and the contact area is small and the contact stress is large, so it is easy to

Plain bearings play a vital role in mechanical vehicles, but they are prone to wear, heat, bite and other phenomena under working conditions. In order to improve the service life of plain bearings, several effective preventive measures are discussed in this paper. First, reasonable assembly and maintenance of bearings

he life of a rolling bearing refers to the number of turns or working hours experienced from the beginning of use to the first appearance of fatigue spalling under rotating conditions. The contact fatigue is random and the bearing life follows Weibull distribution law. Based on this distribution, we can determine a certain range of
