    Tips: Rotary joint working principle.

    Rotary joints typically include a fixture, also referred to as a housing. The housing has an inlet for receiving the fluid medium. The non-rotating seal is mounted in the joint housing. The rotor (ie, the rotating piece) includes a rotary seal and an outlet for delivering fluid to the rotating assembly. In a rotary joint, the sealing surface of the non- rotating seal is typically biased by a spring, medium pressure or other means, then form a sealed connection with the fluid on the sealing surface of the rotating seal. The seal allows the fluid medium to be transported through the rotary joint without significant leakage between the non-rotating portion and the rotating portion.
