Abstract:
A
experimental device for cavitation erosion is established by use of the
mechanism of ultrasonic vibration. The influences of bubbly oil on the
cavitation erosion in journal bearings in engines are investigated in
detail. From analyzing these experimental results it is found that the
bubbly oil decrease the cavitation erosion in engines, and the more the
bubble content is, the more the influence is. The traditional mechanism
of gaseous cavitation erosion is discussed and explained in a new way
according to the experimental results.
