Deublin rotary joint is a high-performance rotary connection device widely used in various industrial fields. The following is a detailed introduction to Deublin rotary joints:

1、 Brand background

Company Name: Deublin Corporation, USA

Established in 1945

Business area: Focusing on the manufacturing of rotary joints, steam joints, siphon tubes, and internal expansion tubes

Technical strength: The production line adopts today's CNC technology, including multi axis function, robot interface, single thread machining function, and radial grinding. With its strong technical development capabilities and product design experience, Dubolin has always been at the forefront of technology in the field of precision connectors, and has been awarded ISO 9001 quality management certification and ISO 14001 environmental management system certification.

2、 Product Features

Innovative design: The Deublin rotary joint is used to ensure that it can withstand high pressure while rotating at high speed and maintain stable sealing performance.

Exquisite processing: The product undergoes precise processing and strict quality inspection to ensure that the quality of each joint meets the highest standards.

Reliable performance: Deublin rotary joints have the characteristics of no leakage, long service life, and easy maintenance, and can operate stably for a long time.

Model serialization: Deublin offers multiple models and specifications of rotary joints to meet the needs of different customers.

3、 Working principle

The working principle of Deublin rotary joint is similar to the movement of a shaft, which connects the rotating shaft on different axes by concentric rings with the rotating outer and inner rings. It uses components such as rollers, needle rollers, inner and outer rings, cover plates, seals, and shells to achieve this function. The precise processing of the sealing surface can reduce the adverse conditions caused by spherical wear. In addition, the rotary joint should contain at least one elastic element (such as a spring or bellows) to ensure the stability and sealing of the joint.

4、 Product type

Deublin rotary joints are mainly divided into two types: one-way and two-way:

Unidirectional: Install rotary joints at both ends of the drum, allowing fluid to enter from one end and exit from the other end; Alternatively, a rotary joint can be installed at one end of the drum to allow fluid to be introduced and discharged, while the rotation of the inner tube relative to the drum remains stationary.

Bidirectional: The drum is equipped with different types of siphon tubes for discharging condensate. This type is mostly used in steam type application scenarios. According to whether the inner tube is fixed or rotating, the bidirectional rotary joint can be further subdivided.

5、 Application Fields

Deublin rotary joints are widely used in various manufacturing industries, including but not limited to:

Paper making: equipment used for drying cylinders, steaming balls, coating machines, calendering machines, etc. in paper machines.

Fiber products: such as bed single refining and bleaching machines, silk machines, flat washing machines, etc. in the textile, chemical fiber, printing and dyeing, and linen industries.

Rubber and plastics: Rubber and plastic processing equipment such as calendering machines, screw extruders, and mixing mixers.

Leather: Processing and manufacturing equipment for artificial leather and synthetic leather, such as coating machines, raw fabric machines, etc.

Printing: rotary offset and gravure printing machines, layered drying equipment, etc.

Chemical and pharmaceutical industries: cylindrical, conical, and drum shaped drying machines, rolling testing equipment, etc.

Food: Grain, food drying equipment, kneading machines, etc.

Mechanical manufacturing: hydraulic presses, hydraulic presses, pneumatic and hydraulic related equipment, etc.

In addition, Deublin rotary joints are also used in various fields such as steelmaking, metal and alloy products, electrical appliances, cigarettes, and building materials.

6、 Maintenance and upkeep

To ensure the long-term stable operation of the Deublin rotary joint, regular maintenance and upkeep are required. Here are some suggestions:

Avoid impact and falling: The interface and internal components of the rotary joint are fragile and should be avoided from impact and falling to prevent damage.

Measurement of concentricity: After installation, concentricity should be measured to ensure the normal operation of the rotating joint.

Pay attention to the direction of thread rotation: For rotary joints with threaded connections, it should be noted whether the thread rotation direction of the inner and outer pipes is the same as that of the drum, and the thread rotation direction of the inner and outer pipes should also be consistent.

Use hose connection: A hose should be used to connect the rotary joint to the pipeline, eliminating rigid connections to reduce joint load and extend service life.

Precautions for inner tube assembly: When assembling the inner tube, attention should be paid to the fit of dimensions and the auxiliary support of weight. It is recommended to use tolerance fit H8/e7 for the fit between the inner tube and the joint of the internal rotary joint.

In summary, Deublin rotary joints play an important role in the field of industrial automation due to their performance and wide range of applications. Regular maintenance and upkeep can ensure the long-term stable operation of the joint and extend its service life.
