Technical Requirements For Mechanical Seals
- Nov 28, 2018 -

1. The radial runout of the equipment shaft should be 0.04 mm, and the axial yaw force should not be greater than 0.1 mm;


2, the sealing part of the equipment should be kept clean during installation, the sealing parts should be cleaned, the sealing end face is intact, and impurities and dust are prevented from being brought into the sealing part;


3. It is strictly forbidden to hit or knock during the installation process, so as to prevent the mechanical seal friction pair from being damaged and the seal from failing;


4. A clean layer of mechanical oil should be applied to the surface in contact with the seal during installation so that it can be installed smoothly;


5. When installing the static ring gland, the tightening screw must be evenly stressed to ensure the vertical requirements of the static ring end face and the axial line;


6. After the installation, push the moving ring by hand to make the moving ring move flexibly on the shaft and have certain elasticity;


7. After installation, the rotating shaft and the rotating shaft should be light and heavy.


8. The equipment must be filled with media before operation to prevent dry friction and seal failure.
