Sealing components for high-speed rotary joints
If an O-ring is used, it is best to add an elastic pressure to the sealing ring to maintain contact with the sealing surface. However, the effect is not very ideal. It is better to use a skeleton seal and a mechanical seal. Generally, bearings are required for rotation. The bearings need to have a bearing cover that is tightly pressed, and the sealing ring can be installed on the bearing cover

Working principle of hydraulic center rotary joint
The structural characteristics and working principle of the central rotary joint. The central rotary joint is mainly used for pipeline connection in hydraulic and pneumatic machinery with rotary motion, such as excavators, cranes, aerial work vehicles and other engineering machinery. It is used to connect hydraulic and pneumatic pipelines of relatively fixed and rotating components, avoiding the entanglement of pipelines during rotational motion when using hoses for connection

Rotating joint extension shaft and motor connection
There is a special type of extension shaft rotary joint in the rotary joint, which adopts an extension design. Both the standard MFQ series rotary joint and the SE series compact rotary joint can be extended into the extension shaft rotary joint series. The most common extension shaft rotary joint is mainly connected to the motor spindle and three grip chuck, and needs to withstand a certain weight and downward tension

Factors affecting the sealing ring of high-pressure rotary joints
igh-pressure rotary joints generally experience leakage problems, and sometimes newly installed high-pressure rotary joints may also experience leakage. There are many factors that can cause leakage, such as aging and deformation of the sealing ring, damage to the corrugated pipe, etc., all of which can cause high-pressure rotary joints to leak
