An O-ring is a type of seal used to prevent the passage of liquid or gases between connected surfaces. These elements have a doughnut shape and are made from elastomers. O-rings have a wide range of applications due to the benefits they offer. These parts are reusable and can compensate for tolerance run out. You also do not need any special installation tools for putting up O-rings. For you to enjoy the benefits offered by these parts, you will have to choose the right one for your application. Otherwise, you will face various issues when using the O-ring. Use these tips to prevent some common O-ring problems.
Determine the Type of Application
There are two general categories for the sealing applications: dynamic applications and static applications. Most of the sealing uses are pseudo-dynamic or pseudo-static. It is hard to find an application that does not have vibration movement. The best way to avoid issues at this stage is by understanding the operating environment of the O-ring. Elements such as high exposure to ultraviolet determine if the use is radial static or radial dynamic. So you have to understand these design aspects before you can choose the right O-ring for your application.
Analyse the Media
After understanding the right O-ring function, the next move is to choose the right elastomer for the liquid you are sealing. Different elastomers are compatible with varying media. It is best to work with experts to help in balancing the suitability of various media with one seal. An O-ring is considered compatible when it shows minimal changes with a particular media. Sometimes, however, people can forget to consider elements such as maintenance and cleaning when choosing O-rings. The elastomer you select should be compatible with all fluids in your application. That way, you are sure to have a smooth operation.
Check Engineering Calculation
There are three crucial design calculations experts need to check for every O-ring application: the compression per cent stretch, per cent squeeze, and volume ratio. Standard application dimensions have calculations in various handbooks in the market. Thus, you will not have to do any more computations. But if you are dealing with a unique O-ring application, you will have to do manual calculations. If you do not do the calculations right, then you will likely experience leakage.
Conclusion
Use the tips above to ensure you get the right O-ring. That will help you avoid many issues that people get with these seals. If you still seem to be experiencing problems, then work with certified O-ring experts.
