1. Clean up the installation location;

2. Clear the wool edge of the sealing parts during the installation;

3. Wipe the lubricating fluid on the sealing part;

4. Keep the cover without damage;

5. Check the correct size of the sealing parts;

6. Install the installation and sealing parts with the corresponding tool installation;

7. Rubber -assisted sealing ring cannot be used for soaking and cleaning gasoline to prevent large deformation and premature aging;

8. The "O" shape sealing ring is installed on the static loop component. It should be natural and not distorted. It is the cross section when the burrs are in a free state;

9. When pushing parts, prevent the "O" shape sealing ring damage. The key damage methods include: the blocking method is:. Crack. Black injury.

10. Precautions for installing the sealing circle

1). Prevent the cover or sealing line when installing the sealing circle

The sealing characteristics of sealing depends on the seal or sealing line. The sealing materials of these components must have temperature resistance, corrosion resistance, anti -aging and other performance, so they consist of soft and elastic materials. Therefore, during the installation of the sealing circle, the cover or sealing line of the sealing parts should be specially protected and caring for the sealing parts, otherwise it will cause huge losses;

2). The installation of the sealing ring cannot be forcibly installed

Most sealing rings are installed in the tube ditch. Pay attention to a certain degree of cooperation during installation. It cannot be forced to install, otherwise it may damage the sealing ring and cause unnecessary losses.

3). Pay attention to the balance when installing the sealing ring. Symmetry

The sealing ring needs to be placed around the effective cover (or lip line). After installation and use, further observation and treatment of sealing circles need to be further observed to avoid the collapse caused by the micro leak caused by changes in the standard of the working conditions (such as pressure).
