Paper Mill Machine High Temperature Steam Yankee Dryer Cylinder Flange Rotary Joint

Rotary joint refers to the pipe connecting device, and the connected pipe can rotate relatively.It can be used to transport gas, liquid, oil and other media.Compact design structure, flange connection, effective integration to customer equipment.
The fluid medium transport pipeline and rotation, reciprocating movement or swing (rotation) move some Angle of equipment connected, not only to ensure the continuous flow of equipment, pipeline transfer fluid, but also to prevent the fluid medium collusion, leakage and external debris into the working medium.Rotary joint is a non-functional part of the machine, but its function has a great impact on the whole machine equipment and the whole factory. 

Main Features of Steam Rotary Joints

1. Concave-surface seal
2. Standard graphite or antimony filled graphite seal material
3. Oilless dual-bearing support
4. Maximum support spacing
5. Prolonged service life and high reliability
6. Easy to replace
7. Rotary type or fixed type siphon

Rotary joints, with the adoption of spring loaded pistonstructure, give the sealing ring a constant pressure and thus maketight its attachment to the lower cap. The lower cap is linked byflange to the spindle nose of the dryer, and the piston remains stablewhile the lower cap rotates synchronously with the dryer, so thesealing ring can move to adapt the angle variation and eccentricity.

1. One way flow type: the rotary joint is installed at both ends of the drum, the fluid enters from one end and discharges from the other end, without inner pipe.
2. One way flow type: a rotary joint is installed at one end of the drum, at the same time, the fluid is introduced and discharged at this end, and the rotation of the inner pipe relative to the drum is static.
3. Two way flow type (inner tube fixed): different from the previous type, there are different types of siphons in the drum to discharge the condensate. This type is mostly used for steam type.
4. Two way flow type (inner tube rotation): this type is used for the structure that the inner tube is relatively fixed with the roller and runs synchronously with the roller. At this time, the fluid is led in by the inner tube and discharged by the outer tube.
5.Two way flow type (inner tube rotation): a siphon is installed in the inner part of the drum which runs synchronously with the drum to discharge the condensate. This type is mostly used for steam type.
