Rotating joint in the packaging and printing industry

In the packaging and printing industry, rotary joints play a crucial role in connection and transmission. It can smoothly input liquids such as thermal oil and cooling water from stationary pipelines into printing equipment components that are in a rotating or reciprocating state, and then discharge these media from the rotary joint, perfectly serving as a sealing device for connection

Repair method for deformation of friction pair in rotary joints

The lifespan of a rotary joint is generally one or two years, and it is inevitable to have problems. Timely maintenance or correction can continue to be used without replacing the joint, which not only wastes money but also time. The longest encountered deformation is the sealing pair, which needs to be corrected to ensure the flatness of the conflicting pair

what is rotary joint

A rotary joint is a transitional sealing device that inputs fluid media from a static system to a dynamic rotating system. Sometimes referred to as a rotary joint or swivel joint, and vice versa. It is a connector that transports media between dynamic and static pipelines. The medium can be air, other gases, liquids, vapors, particles, and other substances
