Know About The Electrical Rotary Joints And Their Applications

In the field of mechanical engineering, a wide range of equipments are being developed every now and then. The invention of new equipments certainly proves beneficial for us in a number of ways. One such device is the Rotary Joint or Union. There are numerous reasons that add to the popularity of the electrical rotary joints, and there are plenty of applications related to the same. But, before we get into the applications, let us know a little about this device.

What is an electrical rotary joint?A rotary joint is basically a union that enables the smooth rotation of the connected parts. This device makes it possible to create a seal between a supply passage and a rotating part. The supply passage can be tubing or pipe. On the other hand, the rotating part can be a cylinder, spindle, drum, etc. Once this seal is established by the rotary joint, it becomes possible for the fluid to pass through the entire system without leaking out, even when the rotating part is in action. When we talk about such fluids, we usually mean different types of heat transfer media or power media. For example, water, steam, thermal oil, coolants, hydraulic fluid, and many more. For those who do not know, there are many other names by which the electrical rotary joint is known as, such as rotating union, rotary coupling, rotating union, hydraulic coupling, etc. So, in short, the main purpose of an electrical rotary joint is to facilitate the flow of fluid from a stationary passage to rotating one.

Before you buy electrical rotary joint, it is vital to mention that these joints are designed and manufactured for a wide range of applications; and, the design varies a little as per the application. In addition, the design also depends on the kind of media the passage will carry. Apart from the fluid category or media type, there are other attributes as well that matters, such as environments, loads, speeds, temperature, number of flow passages, and pressures. Hence, you need to be careful about the technical specifications when it comes to purchasing them.

Knowing about the applications of electrical rotary jointsComing to the applications or uses of this device, there are numerous industries in which it has proved to be effective and useful, such as rotary joints for energy are one of the most widely preferred fields. In addition, these joints are used in heavy equipments, packaging, oil and gas, machine tools, aerospace, and defense.

In the printing industry, the use of electrical rotary joints has become very common. When it comes to printing on plastic films or flexible rolls, these rotary joints are used for hydraulics or air. In the rubber industry, water cooled rolls are majorly used, and the rotary joints prove to be quite effective in this case. Coming to the oil and gas sector, the clutches and brakes designed nowadays are heavily based on the rotary union or joint technology.

So, those were some of the major applications of the electrical rotary joint. You can pick from a wide range of options in terms of connection size and number of pathways. Some of the most commonly used sizes are G1/2 inch, G3/8 inch, G1/4 inch, and G1/8 inch. On the other hand, the number of pathways can be 1 to 16. So, it is your requirements which should determine your selection of electrical rotary joint.
