Analysis and treatment of vibration and heating of mechanical seal

1.Static and dynamic ring end rough.

2.The clearance between the dynamic ring and the sealing cavity is too small, because the pendulum causes the collision.                                                                                               Treatment method: increase the inner diameter of the sealing cavity or reduce the outer diameter of the rotating parts, at least ensure the clearance of 0.75 mm.

3.Sealing and corrosion and temperature resistance, friction pairs inappropriate.                 Processing method：change the material of static and dynamic ring to make it resistant to temperature and corrosion.

4.Lake of cooling or end of the installation of particles containing impurities.                        Treatment method: increasing the pipe diameter of cooling liquid or increasing hydraulic pressure.
