What should be noted when installing mechanical seals?

Mechanical seals are very complex components with high installation requirements. Therefore, there are many precautions to be taken during the installation process. Today, we will share with you the installation precautions for mechanical seals.
1. The radial runout of the equipment shaft should be ≤ 0.04 millimeters, and the axial displacement should not exceed 0.1 millimeters;
2. The sealing part of the equipment should be kept clean during installation, and the sealing parts should be cleaned. The sealing end face should be intact to prevent impurities and dust from entering the sealing part;
3. During the installation process, it is strictly prohibited to collide or strike, in order to avoid damaging the mechanical seal friction pair and causing seal failure;
4. During installation, a layer of clean mechanical oil should be applied to the surface in contact with the seal to ensure smooth installation;
5. When installing the static ring cover, the screws must be tightened evenly to ensure that the static ring end face is perpendicular to the axis;
6. After installation, pushing the moving ring by hand can make it move flexibly on the shaft and have elasticity;
7. After installation, manually rotate the shaft and there should be no feeling of weight or heaviness;
8. The equipment must be filled with medium before operation to prevent seal failure due to dry friction.
