Features of Rotary Union

Media type: Rotating joints are widely used in various media, including but not limited to water, steam, thermal oil, compressed air, hydraulic oil, lubricating oil, coolant, ethylene glycol, cutting fluid, edible oil, kerosene, and other special chemical solvents.

Temperature range: The design of rotary joints needs to consider the working temperature of the medium. Common rotary joints can adapt from room temperature to high temperature (such as 300 degrees Celsius or even higher).

Pressure level: Rotating joints need to withstand media transmission of different pressure levels. For high-pressure systems, joints need to have sufficient strength and tight sealing performance to prevent leakage under high pressure.

Cleanliness requirements: The solid particles or impurities contained in the medium may accelerate the wear of the internal sealing surface of the rotary joint and reduce the service life of the joint.

Chemical compatibility: For media with chemical corrosion, the contact material of the rotary joint must have good corrosion resistance to avoid joint failure caused by chemical reactions.

Flow rate and flow rate: The size and design of the rotary joint should also take into account the flow rate and flow requirements of the medium, to ensure that the equipment can smoothly transport the medium during normal operation.

Application of Rotary Union

Computerized numerical control (cnc) machine cooling: Coolant must be delivered to parts made of metal and other materials undergoing machining. This fluid prevents overheating, maintains dimensional stability, and clears away machined debris.

Hydro dam turbine control: Hydroelectric dams assimilate power as water flows across turbine blades. Hydraulic lines are used to control the opening and closing of gates, and subsequent flow of water.

Floating production storage and offloading (fpso): Toroidal swivels are utilized in mooring systems for offshore vessels which collect oil and gas from subsea reservoirs. These complex systems operate under extreme flow rates while undergoing substantial mechanical stresses.

Liquefied natural gas (lng) loading arms: Loading arms are used to transfer fluid cargo to and from offshore vessels, tanker trucks, and railway cars. They must provide reliable delivery of cargo with leak-free sealing.

Radar cooling systems: Electronic systems on mobile units are in constant use, generate heat, and therefore require cooling systems. Cooling electronic systems in these applications involves specialized designs.

Rotary Union Structure

Pneumatic rotary joint is a rotary connector driven by air pressure, mainly composed of a rotating part and a fixed part. The rotating part includes the rotor and the bearings below the rotor, while the fixed part includes the stator and the sealing ring above the stator. The structure of the rotor and stator is relatively simple, usually with an airflow channel on the rotor. After the gas enters the channel from the gas source, it drives the movement of the rotor through pressure, thereby achieving the rotation connection of the rotor.

Shipping	Shipped by road, sea, rail

FAQ

Q: How do rotary unions work?

A: A rotary union will lock onto an input valve while rotating to meet an outlet. During this time the liquid and/or gas will flow into the rotary union from its source and will be held within the device during its movement.

Q: How do rotary unions work?

Q: How does a rotary union work?

A: A rotary union is a device which provides a seal between a stationary supply passage and a rotating part, thereby allowing the transfer of fluid.

Q: How does a rotary distributor work?

A: The rotary distributor comprises a round distributor having outlet holes arranged peripherally in the horizontal bottom of the housing and connected to outlet pipes.

Q: What is the difference between a rotary union and a swivel joint?

A: A Pneumatic Rotary Union is typically used in applications where only one degree of freedom is required, such as in a robotic arm or a camera mount.
