Cooling issues for high-temperature pump bearing housings
Thread Content
Does the cooling of a high-temperature pump bearing housing cool the lubricating oil or the bearings? Why?
Everything should be cooled, and even the end caps need to be cooled as well
The cooling of the high-temperature pump bearing housing is achieved by cooling the lubricating oil; when the temperature rises, the lubricating oil becomes thicker or carbon deposits form.
If the temperature of the lubricating oil decreases, the bearing temperature will certainly drop as well, since the lubricating oil is used to lubricate the bearings and reduce their temperature.
By checking the water flow, it becomes clear what is being cooled. The bearings are cooled at their bearing housings, and the oil is cooled when it is immersed in oil; however, the end result is the same – heat is removed
General-purpose cooling lubricant to prevent uneven contraction of the bearing outer ring, which could cause vibration and damage
Bearing housing cooling is primarily aimed at cooling the lubricating oil, and this can be achieved by adding cooling water or by using fans.
