Rotary Joints and Siphons

Call to Action

High-Speed Rotary Joints

Structural Features：

With the adoption of spring loaded piston structure, give the sealing ring a constant pressure and thus make tight its attachment to the lower cap. The lower cap is linked by flange to the spindle nose of the dryer, and the piston remains stable while the lower cap rotates synchronously with the dryer, so the sealing ring can move to adapt the angle variation and eccentricity.

Cantilever Type Siphon System

Structure Features：

The excellent property of fixed cantilever siphon makes possible effective drainage under the condition of high speed and low pressure difference. The reliable rigid support enable the equipment to accurately control the liquid level of the condensate water when the equipment is in speed operation, and thus realizes more constant heat transfer at high temperature.

Siphon Key Components

Horizontal pipe locking nut

Siphon bracket Q235 casting

Siphon nozzle SUS304

Siphon elbow (wall thickness 4mm) SUS304

Spoiler Bar

Function of the spoiler bar
The spoiler, made of stainless steel and fixed in the inside of the dryer, to fluctuate the condensate water and thus to enhance the thermal uniformity an drying efficiency

  • Improving the moisture distribution in the paper web on paper machine with quite high thermal conductive uniformity.
  • Enhancing the drying efficiency for PM running at maximum working steam pressure.
  • Shortening the rope threading and paper threading time.

Features

  • SS material with high resistance to corrosion and wear
  • Keep the condensed water of appropriate thickness
  • Separate design for quick installation
  • Light and hollow structure for easy installation

Benefits

  • Improving drying capacity
  • Improving the temperature homogeneity on surface of the dryer, and thus lowering the paper break frequency
  • Lowering the steam pressure in the dryer
  • Decreasing the driving torque and thus the formation of water ring

Suggestions:
Running Speed ＞450 m/min, suggest to install
Running speed ＞600 m/min, must be installed
