Reason for rotating joint failure
Rotary Union/Swivel Joint is a 360 ° rotating fluid dynamic sealing device, whose core function is to transport media such as gas, liquid, oil, etc. from fixed pipelines to rotating or reciprocating parts without leakage, preventing pipeline entanglement and ensuring continuous operation.

Discussion on the Differences in Quality of Central Rotary Joints
Central rotary joint is a sealing device that connects rotating components and fixed pipelines, and transmits hydraulic oil, water, air or electrical signals during relative rotation. It is mainly used for construction machinery such as excavators and shield machines that can rotate continuously 360 degrees

Rotating joint extension shaft and motor connection
Extension shaft of rotary joint is a special structural form of rotary joint, which refers to a section of shaft body extending from the standard rotary joint, used to directly connect the motor spindle or transmission components, achieve sealed transmission of medium (gas/liquid/vacuum, etc.) in the rotating state, and adapt to axial force and installation space limitations

Structure of heat transfer oil rotary joint
The installation of heat transfer oil rotary joint is composed of non rotating parts and rotatable shaft or flange. Firstly, a flexible hose or straight pipe is inserted into the non rotating parts. The non rotating connection part and the upper part formed by the casting are composed of external threads and concave internal threads

Why does the rotary joint swing left and right
Rotary joints are mostly composed of connecting shafts and bearings. If there is swinging, we need to first confirm whether there is clearance in the bearings. Sometimes, at high speeds, the steel beans will rub and become smaller

Reasons for leakage of hydraulic rotary joints
Hydraulic rotary joints are suitable for high torque working environments and are widely used in industries such as machine tool fixtures, automation, metallurgy, wind power, and construction machinery. Because of its high pressure, it is usually called a high-pressure rotary joint, and some special equipment can reach a maximum pressure of 45MPa
