Factors affecting the sealing ring of high-pressure rotary joints

In daily work, high-pressure rotary joints generally experience leakage problems, and sometimes newly installed high-pressure rotary joints may also experience leakage. There are many factors that can cause leakage, such as aging and deformation of the sealing ring, damage to the corrugated pipe, etc., all of which can cause high-pressure rotary joints to leak. What are the factors that affect the sealing ring of high-pressure rotary joints?

Pressure is an important factor affecting the quality of seals. The level of pressure and the length of the pressure cycle have a significant impact on seal damage (such as extrusion). The higher the pressure, the greater the impact of other factors on the performance of the seal, such as temperature, speed, seal material, clearance between the piston and cylinder, and clearance between the piston and cylinder head.
Another issue is that temperature and friction force make it difficult to describe the high and low usage temperatures of a sealing material, as this is the result of a combination of factors. The working temperatures of the piston and piston rod are different, and they need to be selected differently. Another factor that affects seals is the surface roughness, surface characteristics, pressure, medium, temperature, seal material, seal type, and movement speed.
