The water treatment agent PAC is produced using a positive-pressure reaction, and the mechanical seal of the mixing equipment requires pressure supplementation and lubrication. In production, it is common for the lubricant level to rise or fall and for the pressure to decrease; this is caused by leaks in the mechanical seal. Pressure and lubricant must be replenished, or the lubricant must be replaced, as required by the situation. There was an undergraduate who had just started working; he spent two whole afternoons looking at the entire pressurized lubrication system for mechanical seals without managing to understand how it worked. I happened to be going to visit a friend, passed by the workshop, and he stopped me: Sir, could you explain to me how this mechanical seal works? “Oh, this is a pressurized lubricated mechanical seal, used for stirring in positive-pressure reaction vessels. This is a pressurized tank; it has a pressure replenishment port for adding pressure, and a drain port at the bottom for removing waste liquid. “I know that, but I don’t understand how the lubricating oil can circulate inside without a pump No motivation. ” “Have you learned about or heard of a thermal siphon reboiler? The principle is the same. ” “Oh, thermodynamics, which creates microcirculation, right? ” “This is the motivation”
