Product Description

Dryer Cylinder
The dryer cylinder for paper machine is a key part of paper drying.
It is used in drying part of a paper production line. Working with hot steam from steam boiler, dryer cylinder dry wet paper sheets, then the dry paper sheets can be reeled into jumbo rolls. 
The function of the dryer is to dry the moisture in the paper and finish the paper surface.

Dryer Cylinder Turbulators

The purpose of the turbulators is to destroy the condensation water ring formed in the dryer at high speed and generate more turbulence. The turbulators is installed on the inner surface of the dryer. It rotates with the dryer at the same speed, so it will move the water ring to produce turbulence, which is conducive to heat conduction.

Separate design, with light weight, and convenient and quick forinstallation.
High radial and axial strength in overall structure.
Ensuring maximum instaation firmness.
 

Dryer cylinder Siphon

In order to ensure the smooth discharge of condensed water in the dryer and avoid flooding; Make the cylinder surface temperature as high as possible to improve the drying efficiency; In order to reduce the temperature difference on the cylinder surface and make the moisture content of the paper uniform, the selection of siphon becomes the key.

Dryer drainage siphon is basically divided into 2 forms: fixed type and rotary type. The fixed siphon is fixed on a certain point outside the dryer and does not rotate with the dryer; The rotary siphon is fixed in the dryer and rotates with the dryer.

Dryer Cylinder Rotary Joint

The dryer needs steam, and the internal condensate needs to be discharged. But the dryer is a rotating cylinder, so a special joint is needed to complete this task, that is, the steam joint.
Steam in and condensate out are usually completed by a rotary joint at 1 end of the dryer, or steam in and condensate out at 1 end.

How do rotary cylinders contribute to precise rotational control?

Rotary cylinders play a crucial role in achieving precise rotational control in various applications. Here’s a detailed explanation:

1. Actuation Methods: Rotary cylinders utilize hydraulic or pneumatic actuation methods to generate rotational motion. These actuation methods offer precise control over the application of force, allowing for accurate and controlled rotation.

2. Control Valves: Control valves are used to regulate the fluid flow into and out of the rotary cylinder. By adjusting the valve settings, the rotational speed and direction can be precisely controlled, enabling precise rotational control.

3. Feedback Systems: Some rotary cylinders incorporate feedback systems, such as position sensors or encoders, to provide real-time information about the cylinder’s rotational position. This feedback enables precise control over the rotational movement, allowing for accurate positioning and synchronization with other system components.

4. Stroke Adjustment: Rotary cylinders often have adjustable stroke lengths, which allow for precise control over the range of rotational movement. By adjusting the stroke, the rotational angle can be precisely controlled, enabling precise rotational control for specific applications.

5. Positioning Guides: Rotary cylinders may feature positioning guides, such as grooves or slots, that help guide and stabilize the rotational movement. These guides ensure precise alignment and minimize deviations or wobbling during operation, contributing to precise rotational control.

6. Precision Manufacturing: Rotary cylinders are manufactured with high precision to ensure smooth and accurate rotation. The use of high-quality materials, precision machining, and tight tolerances contribute to precise rotational control, minimizing unwanted variations or errors.

7. Integration with Control Systems: Rotary cylinders can be seamlessly integrated with control systems, allowing for precise control over the rotational motion. They can be programmed and synchronized with other system components, such as sensors, actuators, and PLCs, to achieve precise rotational control in complex automation processes.

These factors combined contribute to the precise rotational control achieved through the utilization of rotary cylinders. It’s important to consult manufacturers’ documentation and guidelines for specific information on the capabilities and limitations of rotary cylinders in achieving precise rotational control.
