A rotary union is a device that transfers fluids and gases under high pressure. It can have straight, angled, or multiple ports, and can handle different materials simultaneously. It is often used in production lines, automobiles, and petroleum products. It is made of stainless steel and rubber, and can rotate on one axis to maintain a moving connection. It is versatile and takes up less space than other devices. It is used in various industries, including crude oil processing, chemical industry, commercial food production, and pharmaceutical applications.
A rotary union, or rotary fitting, is a device used to conduct fluids and gases from one point to another, often under high pressure. Also, a rotary union is designed to lock onto an inlet valve as it rotates or rotates to meet an outlet. Many rotary joints incorporate multiple ports, some of which are designed to handle different types of material simultaneously.
A rotary union with a straight port transfers the substance directly through the rotary union. Other designs include an angled port, which drains material at an angle, and multiple ports. A multi-way rotary fitting looks like a perforated cylinder. At the end of the cylinder is a threaded screw with gaskets which locks onto the outlet. The material to be transferred flows into the cylinder and exits the inlet holes.
In the case of a rotary joint with multiple inlets, chambers separated by seals prevent the materials from inadvertently mixing. This type of rotary union is often used in the production of plastics and other petroleum products, where multiple inputs may need to be streamlined, but kept separate.
The rotary joint is designed to withstand large amounts of pressure and heat. Often, rotary unions are constructed of stainless steel to resist corrosion. They also often incorporate ball bearings to keep the rotary joint moving smoothly. The seals are made of rubber and plastic and may need to be changed periodically depending on the type of material being transferred.
The rotary joint works by touching an inlet valve and locking onto another device, such as a manufacturing machine. Since the rotary joint is designed to move, most frequently rotating on one axis, the machinery it is attached to can move, and the rotary joint will rotate with it, meaning that a moving connection can be maintained.
Many assembly lines incorporate multiple rotary joints, because they are highly versatile and take up less space than other devices designed for a similar purpose. Rotary joints also appear in automobiles and other machines that require constant supplies of lubrication, air, or other liquids for moving parts to operate smoothly. Brakes, for example, use rotary joints to maintain a constant supply of pressurized brake fluid. Rotary unions are also used extensively in crude oil processing, chemical industry, commercial food production and pharmaceutical applications.
