Use of emulsion as a medium in rotating unions:
Metalworking and machining technology
In metalworking, an emulsion of water and oil is often used as a cooling lubricant to cool and lubricate both the tools and the machined parts during milling, turning or grinding. Rotating unions transport these emulsions to the rotating tools or machine components, thus preventing overheating and abrasion.
- Application: Cooling circuit systems for processing machines such as CNC lathes, milling machines or grinding machines
- Advantage: Control of tool changes or rotating grippers
Machine tools
Emulsions are used as cooling lubricants in machine tools, e.g. for machining metal or plastic, in order to reduce the generation of heat and increase the service life of the machines and tools. Rotating unions enable the continuous transport of the emulsion to the rotating parts of the machine.
- Application: Supply of machine tools with cooling lubricants during operation, e.g. in machines for drilling, turning or milling.
- Advantage: Ensures continuous and effective cooling of the rotating tools without leakage or segregation of the emulsion.
Food industry
In the food industry, emulsions are often used in the production of mayonnaise, salad dressings, dressings or other emulsified foods. Rotating unions enable the safe transportation of oil-water emulsions in production plants where these components have to be constantly mixed together (agitators).
- Application: Emulsion mixing and processing in food production systems, e.g. in mixing and filling machines.
- Advantage: Enables precise and continuous emulsion supply in mixing systems and at the same time prevents segregation.
Chemical industry
In the chemical industry, emulsions are used in numerous processes, e.g. in the synthesis of polymer solutions or in the petrochemical industry. Rotating unions enable the transfer of emulsions into reactive or mixed substances without impairing the quality of the emulsion.
- Application: Emulsion conveying in systems for the production of reaction mixtures or for the storage and transportation of chemicals in emulsion form.
- Advantage: Prevents the emulsions from separating and enables a stable chemical reaction or material processing.
Printing technology
In printing technology, emulsions such as printing inks are used in certain printing processes. Rotating unions are required to continuously convey these emulsions to the rotating printing rollers or cylinders without impairing the print quality.
- Application: Continuous supply of printing ink or other emulsions to printing machines.
- Advantage: Ensuring a constant and stable supply of printing inks or inks to the machines without any disruptions or loss of quality.
Textile industry
In the textile industry, emulsions are used for various processes such as dyeing, coating and finishing of fabrics. Rotating unions are required to feed these emulsions into machines that require continuously rotating parts, such as coating machines.
- Application: Emulsion supply in dyeing and coating machines.
- Advantage: Enables an even and continuous distribution of emulsions on the textiles without segregation or leakage.
Automotive industry
In the automotive industry, emulsions are used as lubricants and coolants in various manufacturing processes. Rotating unions ensure that these emulsions are fed efficiently to machines such as milling machines or robot arms.
- Application: Supply of cooling and lubricating emulsions to production machines, e.g. for grinding or drilling car parts.
- Benefit: Optimization of lubrication and cooling in automotive manufacturing processes, which increases productivity and extends the service life of the machines.
Note: The applications listed are only an excerpt and are for illustrative purposes. Due to the large number of possible areas of application, not all use cases can be shown here.
