Installation and usage requirements:

1. The radial runout of the equipment shaft should not exceed 0.04 millimeters, and the axial displacement should not exceed 0.1 millimeters;

2. The sealing chamber 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 area;

3. During the installation process, it is strictly prohibited to touch or knock to prevent mechanical seal friction from damaging and sealing failure;

4. During installation, a layer of clean mechanical oil should be applied to the surface in contact with the seal to facilitate smooth installation;

When installing the static ring gland, the screws must be tightened evenly to meet the vertical requirements of the static ring end face and the axis line;

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

7. After installation, rotate the rotating shaft by hand, and there should be no feeling of weight on the shaft;

8. The equipment must be filled with medium before operation to prevent seal failure due to dry friction;
