Deublin is one of the largest rotating union manufacturers in the world and also producers of rotating couplings and rotating joints. Deublin Rotary Unionsare precision mechanical devices that are used for fluid transfer from a supply pipe or a similar stationary source to a rotating piece of equipment. Deublin line rotary unions are used in various industries, including:
- Automotive,
- Machine tools,
- Steel and
- Paper
Also referred to as rotary swivels, rotary couplings or rotary joints,thesecan vary in complexity and in size. Due to this reason,these can be made with multiple passages to ensure your transfer of multiple forms of media in a single device. Such kinds of rotary unions are able to handle different rotational speeds and pressures. Generally, the larger the number of passages is, the lower the amount of pressure and speed it can deal with. Clearly, this indicates why rotary unions from Deublin are so much in demand these days.
How Are Deublin Rotary Unions Used?
Rotary unions from Deublin offer an interface, which allow the transfer of fluid media – such as liquid steam or air, between a static and a rotating component. These are designed to fit various types of media conditions, such as:
- Very low and high temperatures,
- Different types of pressures,such as vacuum applications and various kinds of flows.
Rotary unions, unlike other fluid transfer systems, work for applications – which include any rotating angle combination such as constant rotation in a single direction.
Rotary unions are applied in textile production as well as in the manufacture of:
- Pharmaceuticals,
- Foods,
- Plastics,
- Rubber,
- Paper,
- Chemicals,
- Automobiles,
- Bricks,
- Glasses and more.
These move different types of media, such as:
- Solid materials,
- Slurries,
- Gases,
- Chemicals,
- Pressurized water,
- Steam,
- Hydraulic fluid and
- Vacuum or compressed air
Rotary unions are used also for moving:
- Aviation fuel,
- Natural gas,
- Diesel,
- Gasoline and
- Petroleum products
Devices which move heated air pressurized water steam and hot oil are often composed of stainless steel – that ensures higher corrosion resistance.
Fluorocarbon bearing seals and O-rings rotating unions function at higher pressures and temperatures. In all those applications where misalignment of equipment happens, often there is extra flexibility as offered by bellows type seals.
When it comes to features, there is an integral slip ring in a few rotary union devices for data or electrical power transfer. There is a thru-bore in others for wearing and mounting rotary unions, having a slowing motion implemented for media speed regulation. Devices that have dry running safety feature can work even in the absence of lubrication.
Rotary joints can also be found to be used for medium transfer to moving or rotating machine parts from stationary supply lines. This can also be designed with many flow passages, to deal with different types of media at the same time.
