Regarding the issue of cooling water for the pump
Thread Content
Why do some pumps in the device require cooling water while others do not? What is the reason for using cooling water in pumps? Of course, a hot oil pump must be cooled using cooling water. Why are some cold oil pumps used while others are not?
I suggest you take a look at API610
It depends on where the cooling water goes and what it is used for specifically
The use of cooling water for the pump is determined by the temperature of the material.
Many centrifugal pumps are equipped with cooling water systems, and you can decide whether to use cooling water based on factors such as the temperature of the bearings and mechanical seals.
Decide whether to use cooling water based on the medium temperature and bearing temperature rise.
The part of the cold oil pump that uses cooling water is usually the bearing housing. Regardless of whether it is a pump for heating or cooling, friction occurs as long as the bearings are in operation, and thus heat is generated; all bearings must be cooled. As for why some bearings do not require cooling, this is determined primarily by the amount of heat generated due to high shaft power and high rotation speeds. All cold oil pumps are generally found in large pumps. There’s no need to explain hot oil pumps, right!
