The fluid mixing in the sealing part of the rotary joint is a highly concerning issue, as it may seriously affect the normal operation of the equipment and the purity of the medium. The following is a detailed analysis of the reasons, preventive measures, and solutions for fluid mixing in the sealing part of rotary joints:
1).Sealing failure:
· Sealing surface wear: With long-term operation of the rotary joint, the sealing surface may experience wear, thermal cracking, deformation, or damage, resulting in a decrease in sealing performance.
· Spring failure: After long-term use, the spring may loosen, break, or corrode, unable to provide sufficient thrust to the sealing end face, thereby reducing the sealing effect.
· Auxiliary sealing ring issue: The sealing ring may have cracks, twists, deformations, or ruptures, which can also cause sealing failure.
2).Structural design defects:
· Unreasonable sealing structure design: If there are defects in the sealing structure design, such as excessive sealing gap, uneven sealing surface, etc., it may lead to fluid mixing.
· Multi path design issue: In multi path rotary joints, if the sealing and isolation measures between each path are insufficient, fluid mixing may also occur.
3).Improper installation and maintenance:
· Improper installation: Failure to follow the correct steps and requirements during installation may result in incomplete sealing or damage to the sealed parts.
· Failure to maintain in a timely manner: Failure to replace worn seals and regularly clean the interior of rotating joints may exacerbate the risk of fluid mixing.
1).Optimize sealing design:
· Adopting advanced sealing technologies and materials, such as balanced sealing technology and high-temperature and corrosion-resistant sealing materials, to improve sealing performance.
· Reasonably design the sealing gap and sealing surface to ensure the sealing effect.
2).Strengthen material selection:
· Choose wear-resistant, corrosion-resistant, and high-temperature resistant sealing materials to extend the service life of the seals.
3).Standardize the installation process:
· Follow the installation instructions and specifications provided by the manufacturer to ensure that the sealing part is not damaged during the installation process.
· Use appropriate tools and equipment for installation to avoid rough handling.
4).Regular maintenance and inspection:
· Regularly check the sealing performance of the rotary joint, promptly identify and address sealing failure issues.
· Regularly replace worn seals, springs, and other vulnerable parts.
5).Strengthen training and guidance:
· Provide relevant training to operation and maintenance personnel to enhance their professional skills and awareness.
· Provide detailed operation and maintenance manuals to guide them in correctly operating and maintaining rotary joints.
1).Urgent handling:
· Once the phenomenon of fluid mixing is discovered, the machine should be stopped immediately for inspection and the affected equipment or pipelines should be isolated.
· Clean the mixed fluid and replace damaged seals and other components.
2).Thoroughly investigate:
· Conduct a comprehensive inspection of the sealing part of the rotary joint to identify the root cause of fluid mixing.
· Develop corresponding rectification measures based on the investigation results and implement them.
3).Continuous monitoring:
· Continuously monitor the operation and sealing performance of the rotary joint after the implementation of rectification measures.
· If new problems or hidden dangers are discovered, they should be dealt with and adjusted in a timely manner.
In short, preventing fluid mixing in the sealing part of the rotary joint requires comprehensive consideration of sealing design, material selection, installation process, regular maintenance and inspection, and other aspects. By taking a series of effective preventive measures and timely solutions, the risk of fluid mixing can be minimized and the normal operation of equipment can be ensured.
