A Short Overview of Pneumatic Rotary Union
A rotary joint or pneumatic rotary union is a fitting that is used to enable smooth rotation between a static and a rotational part in a pneumatic system. A pneumatic rotary union ensures that air or gaseous matter can flow easily through different parts of the pneumatic system. Parts or Components Pneumatic rotary unions are generally made of stainless steel to ensure the smooth mobility of the movable part. They are made of four components: Housing Shaft Bearing Seal Function The primary function of pneumatic rotary unions is transporting steam, gases, or any other media to different parts of the machines. Working Principle Pneumatic rotary unions are generally sealing devices. They connect the gas input from the pipeline to the rotating equipment and then discharge steam or gases. These unions work by swirling compressed air through a fixed point. It ensures that the air is not leaking out. A rotating element is mounted on the shaft of a rotating machine called a rotor. ...
