What are Vacuum feedthroughs? Learn with Industry Application Examples
For readers unfamiliar with ferrofluid seals, this article answers the following questions:
• What is the role and importance of ferrofluid seals?
• What types and features do ferrofluid seals have?
• What are the applications of ferrofluid seals across industries?
Let’s first understand the basic concept of ferrofluid seals.
The Role and Importance of Vacuum feedthroughs
As the name suggests, vacuum feedthroughs are used to "maintain vacuum states." While creating a perfect vacuum is difficult in practice, various industries require technologies that create and maintain environments close to a vacuum state.
Maintaining Vacuum State Technology
A vacuum state refers to an environment where the pressure is lower than atmospheric pressure. Creating and maintaining a vacuum requires advanced technology, which is applied in industries like semiconductor manufacturing and vacuum drying. In these processes, maintaining a vacuum is crucial.
Ferrofluid seals are key technologies for maintaining a vacuum. They prevent gas leakage, thereby preserving the vacuum state of equipment even while the shaft is rotating. Depending on the application, the appropriate type of ferrofluid seal should be chosen.
To maintain a vacuum, vacuum pumps are used to evacuate air from the equipment, and vacuum gauges monitor the pressure to ensure the required vacuum level is achieved. Maintaining a vacuum is essential for ensuring high-quality products.
Types and Features of Vacuum feedthroughs
Vacuum feedthroughs can generally be categorized into static seals and dynamic seals, each with the following characteristics:
· Static Seals
Static seals are used between fixed components to prevent leakage, such as between two fixed surfaces. They operate at relatively low pressures and have long lifespans. The materials used are more varied, and the costs are generally lower. Static seals are widely used in vacuum equipment and piping systems.
· Dynamic Seals
Dynamic seals are used between parts that are in relative motion, such as rotating shafts. The design and application of dynamic seals are more complex due to the need to address friction, wear, temperature fluctuations, and pressure changes. Thus, material selection and structural design are crucial.
Moretec designs and manufactures dynamic seals using magnetic fluid, which can prevent gas leakage even during high-speed rotation.
Vacuum feedthrough Applications in Various Industries
Vacuum feedthroughs are essential in industries that require vacuum environments and are widely used to support the production of multiple products.
Semiconductor Manufacturing
The semiconductor production process is extremely precise, and vacuum feedthroughs are used to maintain a vacuum inside the equipment to prevent impurities from entering. Even the smallest particles can affect product quality, so the performance of vacuum feedthroughs directly impacts semiconductor production success.
OLED
OLED uses high-purity organic materials that are easily affected by moisture and oxygen. It is crucial to maintain a high vacuum and clean environment during the manufacturing process, and vacuum feedthroughs play an important role. High-precision processing and special materials ensure excellent sealing performance. As the OLED market grows, the demand for high-performance vacuum feedthroughs is also increasing.
In conclusion, vacuum feedthroughs are widely used across industries and support the production of a variety of products.
