Turbine steam seal cooler

Working principle of the turbine steam seal cooler (diagram requested). Effects of freezing of the U-shaped water seal. Seeking advice from experts
The principle of the turbine steam seal is a vacuum pump; steam passes through a throttling device, which creates a negative pressure at that point to draw away the steam that leaks from the turbine, preventing it from entering the lubrication system； The U-shaped water seal freezes up, preventing drainage; the vapor that leaks out cannot be removed, and thus negative pressure cannot be created. Steam enters the lubricating oil, resulting in lubrication compromised by water presence, with serious consequences
By learning new things every day, you will accumulate rich experience!
The steam seal cooler of a turbine is a small tube-and-plate type cooler
It visually shows white vapor coming from both ends of the turbine, polluting the factory environment. Monitor the moisture content in the oil carefully. Besides, it’s not difficult to deal with a frozen pipe either; acting immediately is the best approach
