In a hydraulic system, two things are very important. One is power and another is precision. To make a system successful, each component has to play an important role. But rotary union is the most important among all.
This component is a versatile part, which plays a critical role. Rotary union transfers hydraulic fluid within rotating machinery.
Do you want to know about the application and functionality of rotary unions? Also, do you want to know about the key considerations to choose and maintain rotary unions?
If yes, then this blog is useful for you. It gives you a deep insight into rotary unions. But before that, you should know what a rotary union is and how it work.
What is a rotary joint?
A rotary union for hydraulics is also known as a rotary union, rotary joint, or swivel joint. This mechanical device allows the transfer of fluid from a stationary source to a rotating component.
The capability of rotary union is very crucial in a hydraulic system because it facilitates the movement of water or oil in different directions under high pressure without any major pressure loss or leakage.
These joints are designed to handle different types of fluids under different pressures, and rotational speeds.
Therefore, they are indispensable in systems where components are required to rotate and maintain a fluid connection.
It is critically important that rotary joints are errorless so that you get high reliability, efficiency, and reliability under demanding conditions.
Functionality and design of rotary unions
Suppose there is a hydraulic system that needs to deliver pressurized fluid to a continuously rotating component.
How is it possible to ensure a seamless transfer of fluid without any leakage or compromising the integrity of the system?
It is possible by having rotary unions because of these functionalities:
- Hydraulic rotary unions act like a bridge between a rotating element and a stationary hydraulic line. The joints make possible the continuous flow of pressurized fluid when the connected platform or shaft moves freely.
- Transfer of fluid: The basic functionality of a rotary joint is to transfer hydraulic fluid from a stationary part to a rotating part in applications like crane arms, rotating tables, or the wheels of a construction machine.
- Prevention of leakage: Rotary joints are designed to prevent leakage of fluid. This is possible when you have high-quality seals, and flawless and precise engineering that perform leakproof flow even under high pressure and rotational speeds.
- Pressure maintenance: In a hydraulic system, pressure maintenance is very important and crucial. Rotary joints are capable of handling high pressures. They ensure that the pressure doesn’t drop while the fluid transfers effectively and efficiently.
- Freedom of rotation: In many hydraulic applications, free rotation of components is needed. At the same time, connection to the hydraulic fluid supply should be maintained.
Rotary joints are vital components in hydraulic systems. Since their role is crucial, you need to pay attention to the precision and perfection of these joints. Get the best joints by checking their specifications.
