Rotary joints are also called rotary unions. They serve as one of the most important devices in various industrial applications.
These components constitute an interface between stationary piping and rotating apparatuses. The basic reason for using these components is to facilitate the conduction of fluids, gases or sometimes signals as well.
Since there are different types of rotary joints, it is important to understand which particular joints are suitable for your specific application.
You should know your requirement first
The primary step is to understand and know your needs. Based on that, you can pick joints of your choice. Then you should consider these parameters.
- Medium: What medium will run through the rotary point? This medium could be air, water, oil, steam, coolant, or sometimes mixture of these. It is important to know about the compatibility of joint materials.
- Temperature: What will be the operating temperature range? You should pick joints that can cope with maximum and minimum temperatures.
- Pressure: what is the operating pressure? The pressure rating of the joint should always exceed the operating pressure.
- Speed: You should know about the revolutions per second of the rotary joint. There is a maximum speed for each rotary joint based on its construction and design.
- Number of Passages: How many passages or paths the medium will flow? For example, single-pass joints best fit basic functions. Multi-pass air rotary joints are fit for complicated projects. It is suitable for transferring fluids or gases simultaneously.
- Space Constraints: How much space do you have to install rotary joints? This is an important consideration.
Additional Considerations
Other than the basic requirements, there are some supplementary considerations also. That can influence your choice. They are seal-cage type, selection of material, and maintenance needs.
You need to evaluate the type of joint that is easy to install, use, and service. Thus, there will be minimum downtime.
Conclusion
Selection of the right rotary joint is a crucial factor. It will help to make the right choice of rotating joint. Therefore, you need to choose the best rotary joint. So that you can ensure you get the best joints that have no leaks or failures.
When you pick the best joints, it expands the life cycle of your equipment. Not just that, you will also get higher efficiency of the system.
Correct selection of quality rotary joints will bring a seamless experience. You should spend some time in research and comparison.
