Sealing Guarantee Measures for Rotary Joints

To ensure the sealing performance and reliability of the rotary joint, the following aspects can be considered and implemented:

1、 Choose appropriate sealing structures and materials

①　Sealing structure design:

Select appropriate sealing structures based on working conditions such as medium, working pressure, temperature, and rotational speed, such as planar seals, spherical seals, and linear seals.

Ensure the processing quality and grinding accuracy of the sealing surface to improve the sealing effect.

②　Selection of sealing material:

Select appropriate sealing materials based on the corrosiveness of the medium, temperature range, and working pressure, such as graphite, silicon carbide, alloy materials, O-rings, etc.

Ensure that the sealing material has good wear resistance, corrosion resistance, and high temperature resistance.

2、 Correct installation and debugging

①　Preparation before installation:

Clean the rotary joint and its connecting pipes to ensure that there are no impurities or dirt.

Check if the sealing surface is flat, smooth, without scratches or damage.

②　Installation process:

Install according to the manufacturer's installation guidelines to ensure a secure and reliable connection between the rotary joint and the pipeline.

Pay attention to adjusting the gap and preload of the sealing surface to ensure the sealing effect.

③　Debugging and testing:

After installation, debug and test to ensure that the rotary joint works properly under the specified working conditions.

Check whether the sealing surface leaks, and if there is any leakage, adjust and repair it in a timely manner.

3、 Regular maintenance and upkeep

①　Regular inspection:

Regularly inspect the rotating joint, including the wear of the sealing surface, the tightening of bolts, the elasticity of springs, etc.

If severe wear or loose bolts are found on the sealing surface, the sealing components or fastening bolts should be replaced in a timely manner.

②　Cleaning and lubrication:

Keep the rotary joint clean and regularly remove impurities and dirt.

Apply lubricating oil as needed to reduce wear and friction.

③　Replace the seal:

If severe wear or failure of the seal is found, it should be replaced with a new seal in a timely manner.

When replacing the seal, it should be ensured that the model, specifications, and material of the seal are consistent with the original seal.

4、 Precautions

①　Avoid excessive friction:

During use, avoid excessive friction and wear on the rotary joint to extend the service life of the seal.

②　Control temperature and pressure:

Ensure that the temperature and pressure experienced by the rotary joint during operation do not exceed its rated values to avoid seal failure.

③　Correct operation:

Follow the manufacturer's operating instructions, operate the rotary joint correctly, and avoid misoperation and damage.

In summary, by selecting appropriate sealing structures and materials, installing and debugging correctly, regularly maintaining and servicing, and following precautions, the sealing performance and reliability of rotary joints can be ensured.
