What is the primary purpose of the lantern ring in a cooling system?

The primary purpose of the lantern ring in a cooling system is to distribute water uniformly around the shaft for lubrication. Lantern rings are typically installed in mechanical seal assemblies, particularly in applications involving pumps and compressors. They serve a vital role in ensuring that there is a consistent flow of lubricating fluid, which helps to minimize wear on the shaft and other moving parts.

By providing a reservoir for the lubricating fluid, the lantern ring ensures an even distribution of the lubricant around the shaft. This is essential for the effective operation of the cooling system, as proper lubrication reduces friction and heat build-up, which can lead to premature failure of components. Additionally, the lubrication also helps to seal the system, preventing contaminants from entering and maintaining the efficiency of the cooling process. This function is critical for the reliability and longevity of the cooling system's operational components.
