Fracture of the rotating ring of the mechanical seal in the reaction vessel
Thread Content
During the use of the double-end mechanical seal in the reaction vessel, the pressure in the lubricating oil balance tank increased suddenly and then dropped to zero within a few dozen seconds; thereafter, the lubricating oil started to leak. Upon disassembly, it was found that the moving ring of the mechanical seal was broken. Could this be related to the rapid addition of solid materials while the mixer was operating at full speed?
Is the pressure inside the kettle positive or negative? Negative pressure is very likely!
It’s a slight positive pressure, around 0.003 MPA
Which side’s moving ring is broken, the medium side or the atmospheric side?
Mechanical seal for double-ended reaction vessels, with a structure comprising a moving ring in the middle and static rings on top and bottom
