Hydraulic rotary joint is a device used to connect rotating components in hydraulic systems. Its working principle is to use a sealing structure and axial channels to achieve continuous transmission, sealing, and rotation of hydraulic oil.
Hydraulic rotary joints are usually composed of two rotating parts, inner and outer, with the inner part fixed to the mechanical equipment and the outer part freely rotatable.
A sealing structure is used between two rotating components to ensure that hydraulic oil does not leak out.
Meanwhile, hydraulic oil can be transmitted from fixed components to rotating components through internal axial channels, achieving continuous operation of the hydraulic system.
When hydraulic oil flows into the rotary joint from the system during operation, it first enters the rotating components through the axial channel.
As the rotating components rotate, hydraulic oil will enter the sealing structure through the axial channel and be sealed inside.
At the same time, the sealing structure can rotate, allowing hydraulic oil to be freely transmitted without being affected by the rotation of the hydraulic rotary joint.
The sealing structure of hydraulic rotary joints usually uses O-rings or rotary seals to ensure that hydraulic oil does not leak during rotation.
These sealing structures will more tightly seal the hydraulic oil when subjected to pressure, ensuring the reliability of the system's operation.
Hydraulic rotary joints are widely used in various fields such as engineering machinery, metallurgical equipment, ships, and aerospace, achieving effective connection between mechanical equipment rotation and hydraulic transmission.
Through reasonable design and manufacturing, hydraulic rotary joints can withstand harsh conditions such as high pressure, high temperature, and high-speed rotation, ensuring the safe and reliable operation of the system.
