Address: 1st Floor, No. 2, Shuang D Port 7th Street, Economic and Technological Development Zone, Dalian, Liaoning Province

Company website: https://www.deublin.com/zh-CN

Company Overview

In 1945, Luke Dulle and Dick Lynn founded the company to revolutionize the operation and performance of rotating equipment. They combined their last names and named the new company DuBois Company. Its first product was an innovative rotary joint design that included a balanced mechanical seal. At the time, the most popular type of sealing mechanism was a pressure-type seal. These seals relied on system pressure to maintain mating surface friction, which proved problematic as equipment speeds increased. In printing presses, in particular, pressure-type seals were prone to rapid wear. Luke saw an opportunity to improve on industry standards, and the resulting design was an immediate success. By designing the mechanical seal into a rotary joint, Luke brought the company to the forefront of the industry and fueled DuBois Company’s growth, which continues to this day. In addition to printing presses, Luke went on to design joints for a wide range of applications, including air clutches, gearboxes, machine tool spindles, textile equipment, continuous casting machines, paper machine polishing machines, and rubber manufacturing machinery. The design proved so effective and reliable that DuBois products were used in virtually any industry that needed to transfer air, water, oil, or hydraulic fluid from a stationary source to a rotating portion of equipment. A few years after the company's successful start, Dick decided to focus on another business and he sold his shares to Luke. Dublin was acquired by the Swiss-based privately held industrial company HOERBIGER AG in 2019.

Hydraulic Rotary Joint Information

What is Hydraulic Rotary Joint

A Hydraulic Rotary Joint, also known as a hydraulic rotary union or swivel joint, is a mechanical device designed to transfer hydraulic fluids from a stationary source to a rotating component while maintaining a sealed connection. It ensures that the fluid can flow smoothly and continuously, even as the connected parts rotate relative to each other.

History of Hydraulic Rotary Joint

The first rotary joint was designed and built in August 1933 by R.O. Monroe and L.D. Goff, in conjunction with a local mill. While the early years were focused on sealing steam and water joints, today there are thousands of configurations of standard and custom rotary joints.

Purpose of Hydraulic Rotary Joint

Hydraulic Rotary Joints serve multiple purposes:

Sealed Connection: The primary function is to prevent fluid leakage while allowing rotation.
Fluid Transfer: It facilitates the transfer of various fluids, including oils, water, air, steam, and other media.
Rotation: The joint allows one part (the shaft) to rotate while the other part (the housing) remains stationary.
Versatility: Hydraulic rotary joints can be designed for single-way, double-way, or multi-way fluid transfer, depending on the application requirements.
Durability: They are built to withstand the pressures, temperatures, and environmental conditions of the specific application.

Principle of Hydraulic Rotary Joint

The principle of a hydraulic rotary joint involves the transfer of hydraulic fluid from a stationary source to a rotating component. The joint consists of a stationary housing connected to the fluid supply and a rotating shaft connected to the rotating equipment. Seals prevent fluid from escaping between the stationary and rotating components, while bearings support the rotating shaft and ensure smooth movement.

Features of Hydraulic Rotary Joint

Some key features of Hydraulic Rotary Joints include:

High Pressure Handling: Capable of handling high pressures, making them suitable for heavy-duty applications.
Multiple Ports: Many hydraulic rotary joints incorporate multiple ports, some of which are designed to handle different types of material simultaneously.
Customizable: Can be tailored to meet specific application requirements, including operating performance, cost, and delivery.
Reliability: Properly designed and maintained hydraulic rotary joints can significantly extend the life of the equipment they serve.

Types of Hydraulic Rotary Joint

There are several types of Hydraulic Rotary Joints, primarily differentiated by their design and application:

Single-way Rotary Joints: Allow fluid transfer in one direction only.
Double-way Rotary Joints: Enable fluid transfer in both directions without mixing the fluids.
Multi-way Rotary Joints: Can handle multiple fluids simultaneously, directing them into different systems without cross-contamination.
Hydraulic Rotary Unions: Designed specifically for high-pressure hydraulic applications.
Pneumatic Rotary Union: Used for air or vacuum applications, often in automated machinery.

Precautions for using Hydraulic Rotary Joint

When using Hydraulic Rotary Joints, consider the following:

Proper Installation: Ensure the hydraulic rotary joint is installed according to the manufacturer's instructions to ensure proper operation and prevent damage.
Regular Maintenance: Periodically inspect and maintain the hydraulic rotary joint to ensure its performance and longevity.
Operating Conditions: Ensure the hydraulic rotary joint is suitable for the operating temperature and pressure of the system to prevent failure.

Things to consider when purchasing Hydraulic Rotary Joint

When purchasing Hydraulic Rotary Joints, consider:

Media Type: Choose a hydraulic rotary joint suitable for the specific fluid or gas being transferred.
Flow Passages: Determine the number of flow passages required for the application.
Max. Pressure: Ensure the hydraulic rotary joint can handle the maximum pressure of the system.
Max. Speed: Ensure the hydraulic rotary joint can operate at the required speed.
Flow Passage Size: Select the appropriate flow passage size for the application.
Brand and Quality: Opt for reputable brands known for their quality and reliability to ensure the performance and longevity of the hydraulic rotary joint.

Terms of Hydraulic Rotary Joint[!--empirenews.page--]

Some common terms associated with Hydraulic Rotary Joints include:

Housing: The stationary part that connects to the fluid supply.
Shaft: The rotating part that connects to the rotating equipment.
Seals: Prevent fluid from escaping between the stationary and rotating components.
Support the rotating shaft and ensure smooth movement.
