Sealing technology effectively reduces the leakage rate of rotary joints through a series of measures, mainly including the following aspects:
1) Corrosion resistance: Select sealing materials with excellent corrosion resistance, such as polytetrafluoroethylene (PTFE), polyurethane, etc., based on the type of medium that the rotary joint comes into contact with, to prevent corrosion and erosion of the sealing components by the medium and maintain sealing performance.
2) Wear resistance: Choose sealing materials with good wear resistance to reduce the wear of seals caused by long-term friction, extend the service life of seals, and thereby reduce leakage rates.
3) Elasticity: For rotary joints that use elastic seals, such as O-ring seals, choose sealing materials with good elasticity to ensure that the seal can maintain sufficient sealing pressure under different working conditions and prevent medium leakage.
1) Reasonable gap: Design a reasonable sealing gap to ensure that the seal can tightly fit when subjected to medium pressure, forming an effective sealing barrier. Excessive or insufficient clearance can lead to seal failure, thereby increasing the leakage rate.
2) Multiple sealing: Adopting multiple sealing structures, such as combination sealing gaskets, sealing rubber hoses, etc., to form multiple sealing barriers to improve the reliability and safety of the seal. Even if one seal fails, other seals can still play a supplementary role and reduce the leakage rate.
3) Self sealing design: Utilizing the pressure of the medium itself or the structural characteristics of the rotating joint to achieve self sealing design. This design can compensate for the wear and aging of the seals to a certain extent, reducing the leakage rate.
1) High precision machining: Ensure the machining accuracy of the sealing surface, making it flat and smooth, without defects such as scratches and burrs. High precision machining can reduce friction and wear between sealing surfaces and improve sealing performance.
2) Correct installation: Install the seals according to the prescribed procedures and requirements, ensuring that the seals are installed in place and undamaged. Meanwhile, during the installation process, pay attention to keeping the sealing surface clean and dry to avoid impurities and moisture from entering the sealing surface.
1) Regular inspection: Regularly inspect the sealing performance of the rotary joint, including the wear of the sealing components, the flatness of the sealing surface, and whether there are any leaks. Regular inspections can promptly identify and address potential leakage issues.
2) Maintenance: Perform necessary maintenance work on the rotary joint, such as cleaning the sealing surface, replacing worn seals, etc. These tasks can maintain the good condition of the rotary joint and reduce the leakage rate.
1) Application of new materials: With the continuous development of materials science, new types of sealing materials continue to emerge. By applying these new materials, the sealing performance of the rotary joint can be further improved and the leakage rate can be reduced.
2) Intelligent monitoring technology: Real time monitoring and early warning of the operating status of rotary joints using intelligent monitoring technology. Once abnormal situations such as leaks or excessive vibrations are detected, immediate measures can be taken to prevent the fault from escalating and losses from worsening.
In summary, sealing technology effectively reduces the leakage rate of rotary joints and ensures production safety and environmental protection through reasonable selection of sealing materials, optimization of sealing structure design, improvement of processing and installation accuracy, regular inspection and maintenance, and application of technological innovation.
