Ultra High Vacuum – Understanding Vacuum Technology

Ultra high vacuum is now at the forefront of modern research, which is of little surprise when you consider that vacuum is something we have been researching since the 17th century. So, what is it? In physics, vacuum is defined as a state of emptiness, which is accomplished via experiment. In basic terms, it is nothing, i.e. a state of space that is completely devoid of matter. This cannot be achieved in practice, however, which is why we refer to a vacuum when the air pressure in the space is below the atmospheric pressure. For more information on UHV technology, read on.

The Uses Of UHV

Before discussing vacuum technology use, let’s explain it in further detail. Air is a mixture of gas that features roughly 1025 particles per m3 at one bar air pressure. The gas mixture in the atmosphere is composed of 21% oxygen, 78% nitrogen, and 1% of other gases. All gaseous materials must be eradicated from a space for a state of vacuum to be achieved. This results in very low pressure, as only a small number or no particles are contained therewith. Pressure is calculated as force/area, and zero pressure is a state of absolute vacuum. This is rarely achievable in reality because particle density can still be high although pressure is low, as low as 10-11 mbar. Essentially, the fewer particles, the lower the pressure. So, what about the uses of ultrahigh vacuum? Vacuum plays an important role across all areas of science. In field theory and quantum physics, for instance, there is a focus on particles that, when in a vacuum, can be examined with greater accuracy. The impact of a vacuum on organisms is of interest in biology. And when it comes to chemistry, investigations regarding the reactions of substances in a vacuum are carried out. The uses of an ultra high vacuum extend much further than this. Vacuum technology has played a significant role in developing and implementing handling technology innovations, for example, the rotating, holding, lifting and transporting of all kinds of parts. UHV vacuum technology has also played a crucial part in vital industrial procedures. Many of them, for instance mass spectroscopy and semiconductor manufacture, would not be possible without it.

UHV Ultra High Vacuum In Handling Technology

Let’s take a look at UHV ultra high vacuum in handling technology in further detail. From securing and checking to changing quantities and storing, handling can be divided into a number of different areas. Vacuum technology has proven to be highly effective in handling a number of different parts and materials, opening up completely new solutions and areas of application for handling technology. There are many advantages associated with high pressure vacuum feedthrough being used in handling technology, including the fact that it can be adapted to suit many requirements. Additionally, costs, including maintenance costs, are low; and fast cycle times are possible. In addition to this, vacuum technology means low weight, i.e. suitable for highly dynamic movement, as well as space-saving, compact designs, and the gentle handling of fragile parts. However, there are a number of factors that need to be considered when determining whether to use vacuum technology. This includes the shape of the work-piece surface; the speed per unit of time for cycle completion; the weight of the work-piece; and the conveying distances and stroke travel for handling. The roughness of the work-piece surface should also be considered, as well as the temperature of it or its surface.
