ROTARY JOINTS

Rotary joint also known as rotating joint, rotary union, swivel joint etc. are a system of dynamical sealings. The rotary joint is a mechanical device that allows transfer of working medium from a stationary source (stationary supply pipe) to a rotating machinery (cylinder, drum, roll or spindle) for cooling, heating or transfer of fluid power.

The classification of rotary joints primarily encompasses categories based on performance parameters, medium type, flow path, sealing structure, connection method, application field, sealing material, and motion state.

In practical use, the application scenarios and requirements for rotary joints are often comprehensive. For example, a joint may serve as both a high-speed, high-pressure single-channel rotary joint for water applications

A rotary joint is a fluid dynamic sealing device that transfers fluid medium from a fixed pipeline to a pipeline or equipment that rotates or swings at an angle.  The sealing principle is diverse. For example, spherical sealing relies on the axial displacement of the housing driven by a spring to compensate for the wear of the sealing graphite, thus achieving the sealing and isolation of the medium from the outside. [2] In addition, there are various sealing forms such as planar sealing, cylindrical elastomer sealing, labyrinth sealing,  and so on

Rotary joint are used in the following industries: steel industry, paper industry, rubber industry, textile industry, plastic industry, food and medical industry, converting industry and printing industry.
