Product Description

Dryer Cylinder Hood / Headcover:

Rotary Joint And Siphons: 

The drying section is the paper machine in the steam consumption of most parts, generally accounting for 55% of the total energy cost of the paper machine. Therefore, the adoption of advanced steam and condensate systems can increase production capacity increase paper machine efficiency, reduce drying costs, and increase profits. Therefore, the optimization scheme for drying cadres focuses on steam systems and condensate water transfer systems, which include steam rotators, stationary and rotating siphons, and associated components.

Metal hoses: 

Metal hoses, attached to the rotary joints on each drying can play a critical role in achieving this outcome. They flex, absorb vibration, and operate at the temperatures required to deliver steam to and drain condensate from the cans. When needed, their corrosion resistance prolongs service life.
Max.Pressure: <1.6MPa
Max.Temperature: <320ºC
Media: Water/Steam/Oil/Various fluids

Turbulator Tube Bars:

Made of stainless steel and installed on the inside of the dryer, it creates resonant waves in the condensate film to increase condensate turbulence and therefore, increase the rate of heat transfer.
Feature:
1. High resistance to corrosion and wear
2. Improving drying capacity
3. Improving the temperature homogeneity on the surface of the dryer, and thus lowering the paper break frequency
4. Lowering the steam pressure in the dryer
5. Decreasing the driving torque and thus the formation of the water ring
6. Separate design for quick installation

Gear Wheel of Dryer Cylinder:

The gear wheel is mainly the large gear on the top of the dryer. It is mainly divided into positive gear, large gear, large gear processing, bevel gear and helical gear. In addition, the nonstandard gear should be made according to the drawings provided by the customer.
