What supplies the main feed pump bearing cooler?

The main feed pump bearing cooler is typically supplied with service water. This water is specifically used for cooling purposes in various equipment within a plant, including the bearings of the main feed pump. The cooler is essential to maintain optimal operating temperatures and ensure that the pump operates efficiently and safely.

Service water is widely accessible, stable in temperature, and meets the necessary quality standards for effective cooling. It is a dedicated source for auxiliary systems, making it the preferred choice for cooling as it is less susceptible to changes in environmental conditions compared to sources like river water.

While cooling water can come from various sources, it is often more generalized and may not be as specifically earmarked for auxiliary equipment like the bearing cooler. Similarly, river water may contain particulates and organic material that can compromise the integrity of the cooling system, making it less desirable. Condensate water, while pure, does not provide the necessary flow rates or cooling properties needed for such applications as it is typically involved in other processes within the plant.

In summary, service water serves as a reliable and effective means of cooling the bearings in the main feed pump, ensuring optimum performance and longevity of the equipment.
