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.

Can rotary cylinders be applied in both mobile and stationary machinery?

Yes, rotary cylinders can be applied in both mobile and stationary machinery. Here’s a detailed explanation:

1. Mobile Machinery: Rotary cylinders find extensive use in mobile machinery, such as construction equipment, agricultural machinery, material handling equipment, and transportation vehicles. In these applications, rotary cylinders enable controlled rotational motion for various functions, including steering, lifting, tilting, opening and closing attachments, and actuating hydraulic brakes.

How does a rotary cylinder differ from other types of hydraulic cylinders?

A rotary cylinder differs from other types of hydraulic cylinders in several ways. Here’s a detailed explanation:

Principle of Operation:

A rotary cylinder is designed to convert fluid power into rotational motion, while other types of hydraulic cylinders primarily provide linear motion. While standard hydraulic cylinders extend and retract in a straight line, a rotary cylinder generates rotary or swinging motion.


Rotary cylinders utilize different mechanisms to produce rotary motion. They may employ rack-and-pinion mechanisms, vane mechanisms, or gear mechanisms, depending on the specific design. In contrast, other types of hydraulic cylinders typically use a piston and cylinder arrangement to generate linear motion.

Direction of Motion:

Rotary cylinders produce rotational motion around a fixed axis or pivot point. The direction of rotation can be clockwise or counterclockwise, depending on the design and configuration of the cylinder. In contrast, other hydraulic cylinders provide linear motion in a straight line, either extending or retracting along the axis of the cylinder.


Rotary cylinders are commonly used in applications where rotational movement is required, such as rotary indexing tables, robotic arms, and conveyor systems. They are suitable for tasks that involve swinging, rotating, or indexing motions. On the other hand, other types of hydraulic cylinders are used in applications that primarily require linear motion, such as lifting, pushing, or pulling.

Advantages and Disadvantages:

Rotary cylinders offer certain advantages over other types of hydraulic cylinders. They provide compact and efficient means of generating rotary motion, allowing for versatile applications. Rotary cylinders can deliver high torque output and precise control over rotational motion. However, one potential disadvantage is that they may have a more complex design and require additional components compared to standard hydraulic cylinders.

Fluid Medium:

Rotary cylinders can be powered by either hydraulic fluid or compressed air, depending on the specific design and application. Other types of hydraulic cylinders also utilize hydraulic fluid as the power medium. The choice of fluid medium depends on factors such as the desired force and speed, environmental considerations, and system requirements.

It’s important to consult the manufacturer’s documentation and guidelines for specific information on the selection, installation, and operation of rotary cylinders and other types of hydraulic cylinders for different applications.
