Requirements and standards for the seal fluid pressure and medium pressure at the two mating surfaces of mechanical seals
Thread Content
Excessive back pressure on the stationary and rotating rings leads to unstable liquid films, which can result in dry grinding between these rings. What are the appropriate ranges and standards for this back pressure?
The P-sealing chamber is provided by the equipment manufacturer. Sealing fluid pressure (isolating fluid) = P-sealing + (0.14～0.41) MPa
Is P-seal the process pressure, or the pressure of the medium inside the reactor?
