Common problems and solutions for metal O-shaped hollow sealing rings

Metal O-shaped hollow sealing rings are widely used in industrial fields due to their excellent sealing performance and corrosion resistance. However, in the process of using metal O-ring hollow seals, some common problems are sometimes encountered, as described below, and corresponding solutions are provided:

Leakage problem: Metal O-shaped hollow sealing rings may have leakage problems under high pressure, high temperature or vibration environment. The cause of leakage may be damaged sealing ring, improper installation or uneven sealing surface. Solutions include regularly replacing seals, ensuring seals are installed correctly and tightened appropriately, and ensuring sealing surfaces are flat.

Seal ring solidification problem: Metal O-shaped hollow seal rings may solidify after long-term use, resulting in reduced elasticity and inability to seal effectively. Solutions include regular inspection and replacement of seals to avoid prolonged exposure to high temperature environments or corrosive media.

Friction and wear problem: Metal O-shaped hollow sealing rings are prone to wear in dynamic sealing or high friction environments, affecting the sealing effect. Solutions include using sealing materials with better wear resistance, rationally designing the sealing structure, and properly lubricating the sealing parts to reduce friction and wear.

Temperature change problem: When the temperature changes greatly, the metal O-shaped hollow sealing ring may change in size or lose elasticity, resulting in a decrease in sealing effect. Solutions include selecting sealing materials that accommodate a wide temperature range, leaving appropriate sealing margins, and avoiding drastic temperature changes.

Chemical corrosion problem: Metal O-ring hollow seals may corrode in certain chemical media, resulting in reduced sealing performance. Solutions include choosing sealing materials with better corrosion resistance, understanding the properties of the medium in advance and taking corresponding protective measures.

Conclusion: Common problems that metal O-ring hollow seals may encounter during use include leakage, solidification, friction and wear, temperature changes, and chemical corrosion. In response to these problems, users can take corresponding solutions to ensure the normal operation and service life of the sealing ring. However, in order to avoid problems to the greatest extent, users should comprehensively consider factors such as the working environment, medium characteristics, and the material and design of the sealing ring when selecting metal O-shaped hollow sealing rings, and conduct regular inspections and maintenance to ensure their good performance. Sealing effect.
