Several factors in the application of hazardous coating O-rings

With the needs of production and life, people have put forward higher requirements for sealing products. Coated O-ring seals are commonly used seals in hydraulic systems, but it is inevitable that they will also encounter some impacts on their performance during application. Today, the editor will take you to understand several application factors that are harmful to the sealing ring.

1. Hardness and softness: the different softness and flexibility of rubber products can affect the sealing effect of sealing. At that time, it is prone to squeeze gap, too much support, too high strength, and no rebound.

2. Gap: The gap problem can be divided into several points. One is because of the material configuration problem, which leads to poor resilience and insufficient stretching force, which makes the sealing ring prone to leakage during use. There is also the processing problem of the manufacturer. If the processing is too brittle, the edge of the product will be too thin, if the processing is soft, it will cause the surface of the product to bubble, and gap problems will occur after long-term force stretching.

3. The whole supporting process: The installation position of the coated O-ring seal is mainly in the pipe trench, plan view and convex groove. Due to the different installation height, the installation method is also different, which makes the whole process of projecting support different. In order to ensure its tightness, it should be pre-embedded before installation, and the installation method and the support level should be distinguished, otherwise it is easy to shorten its service life in advance.

Several elements that harm the application of coated O-rings are introduced here. It can be known that the hardness of the material, the size of the gap, and the entire supporting process can affect its sealing effect.
