The stability and reliability of the water supply cooling system are essential guarantees for the safe operation of units in urban flood control hub projects. As an important auxiliary system in pumping station projects, the forced internal circulation water supply system ensures smooth operating conditions of pumping station units under long-term and high-load operation by providing stable and efficient cooling water, thereby effectively preventing equipment failure or damage caused by overheating. With the continuous optimization of cooling systems in hub projects, the application of intelligent monitoring and control modules in water supply systems enables real-time monitoring and intelligent control of the circulating system matched with bearing coolers, and improves the operation stability and safety of pumping stations under remote centralized control.
