What is the function of the shaft seal nitrogen?
Thread Content
The horizontal tank features dual-axis stirring and shaft seal cooling fluid; now nitrogen is to be supplied to the shaft seals. The material used is quite sticky, and this tank is a vacuum tank
Prevent material from leaking at the dynamic seal. It utilizes the principle that the pressure of nitrogen is greater than that of the material to create a seal. So nitrogen is used; this gas does not react chemically with the material, and it is usually dry nitrogen.
Nitrogen was not previously added to the shaft seal; the stirring shaft seal leaked a few times
It depends on the severity of the leakage; if it’s not serious, it can be ignored, but if it is serious, measures need to be taken to address it. Nitrogen sealing is the best method as a dynamic seal, if conditions permit. The hazards of leakage include not only environmental damage but, more importantly, damage to the bearings and sealing gaskets.
If it comes into contact with the material, it will break through the air immediately
