A rotary joint, also referred to as a rotary union or rotating union, is a rotary sealing device that connects rotating equipment to fixed piping for the transfer of steam, water, thermal oil, coolant, hydraulic oil, air, and other media.
Here are some key points about rotary joints:-
Function: Rotary joints provide a seal between a stationary supply passage (like a pipe) and a rotating part (such as a drum or cylinder), allowing the fluid to flow into and out of the rotating part without leaks.
Components: They typically consist of a housing, a shaft, bearings, and seals. The housing holds all the elements together, the shaft carries the medium through the rotary joint, and the bearings and seals ensure smooth operation and prevent leaks.
Applications: Rotary joints are used in various industries, including manufacturing, paper production, food processing, and chemical processing, where they facilitate the transfer of fluids in rotating machinery.
Types:-
There are different types of rotary joints designed to handle various pressures, temperatures, and media :-
Mono Flow (For Hot/Cold Water)
Dual Flow (For Hot/Cold Water)
High Temperature (For Thermic Fluid)
Steam Application
Multi-Port
