  • 1 the History of Vacuum Science and Vacuum Technology
    1 1 The History of Vacuum Science and Vacuum Technology The Greek philosopher Democritus (circa 460 to 375 B.C.), Fig. 1.1, assumed that the world would be made up of many small and undividable particles that he called atoms (atomos, Greek: undividable). In between the atoms, Democritus presumed empty space (a kind of micro-vacuum) through which the atoms moved according to the general laws of mechanics. Variations in shape, orientation, and arrangement of the atoms would cause variations of macroscopic objects. Acknowledging this philosophy, Democritus,together with his teacher Leucippus, may be considered as the inventors of the concept of vacuum. For them, the empty space was the precondition for the variety of our world, since it allowed the atoms to move about and arrange themselves freely. Our modern view of physics corresponds very closely to this idea of Democritus. However, his philosophy did not dominate the way of thinking until the 16th century. It was Aristotle’s (384 to 322 B.C.) philosophy, which prevailed throughout theMiddleAgesanduntilthebeginning of modern times. In his book Physica [1], around 330 B.C., Aristotle denied the existence of an empty space. Where there is nothing, space could not be defined. For this reason no vacuum (Latin: empty space, emptiness) could exist in nature. According to his philosophy, nature consisted of water, earth, air, and fire. The lightest of these four elements, fire, is directed upwards, the heaviest, earth, downwards. Additionally, nature would forbid vacuum since neither up nor down could be defined within it. Around 1300, the medieval scholastics began to speak of a horror vacui, meaning nature’s fear of vacuum.

  • Introduction to the Principles of Vacuum Physics
    1 INTRODUCTION TO THE PRINCIPLES OF VACUUM PHYSICS Niels Marquardt Institute for Accelerator Physics and Synchrotron Radiation, University of Dortmund, 44221 Dortmund, Germany Abstract Vacuum physics is the necessary condition for scientific research and modern high technology. In this introduction to the physics and technology of vacuum the basic concepts of a gas composed of atoms and molecules are presented. These gas particles are contained in a partially empty volume forming the vacuum. The fundamentals of vacuum, molecular density, pressure, velocity distribution, mean free path, particle velocity, conductivity, temperature and gas flow are discussed. 1. INTRODUCTION — DEFINITION, HISTORY AND APPLICATIONS OF VACUUM The word "vacuum" comes from the Latin "vacua", which means "empty". However, there does not exist a totally empty space in nature, there is no "ideal vacuum". Vacuum is only a partially empty space, where some of the air and other gases have been removed from a gas containing volume ("gas" comes from the Greek word "chaos" = infinite, empty space). In other words, vacuum means any volume containing less gas particles, atoms and molecules (a lower particle density and gas pressure), than there are in the surrounding outside atmosphere. Accordingly, vacuum is the gaseous environment at pressures below atmosphere. Since the times of the famous Greek philosophers, Demokritos (460-370 B.C.) and his teacher Leukippos (5th century B.C.), one is discussing the concept of vacuum and is speculating whether there might exist an absolutely empty space, in contrast to the matter of countless numbers of indivisible atoms forming the universe. It was Aristotle (384-322 B.C.), who claimed that nature is afraid of total emptiness and that there is an insurmountable "horror vacui".

  • WOB-L Pumps White Paper
    SSttrraiaighghtt TTalalkk onon WWOOBB--LL® P Pisisttonon P Puummppss Whether for Pressure or Vacuum, These Versatile Pumps May Be Just What You Need By David C. Droege OEM Product Specialist Thomas Products Division Gardner Denver, Inc. If you work with pressurized air or vacuum systems, chances are you’ve either specified or considered a pump that uses WOB-L piston technology. It’s no wonder. You’ll find WOB-L pumps so small that they fit in the palm of your hand, with lots of room to spare. You’ll also find double- cylinder versions that require both arms and a strong back to lift. And all sizes in between. WOB-L piston pumps represent what is arguably the most versatile pressure and vacuum technology available today. Despite this versatility, however, selecting the appropriate WOB-L piston pump is not a job for the uninformed; even more basic, WOB-L technology is not necessarily the best choice for every application. STEP 1: ASSESS THE UNIVERSE OF TECHNOLOGIES No single air pressure or vacuum technology is best across the board, as Figures 1 and 2 on the next page demonstrate. Flow, pressure and vacuum charts, commonly available in pump manufacturers’ literature, will help get you in the ballpark. In addition, here are chief characteristics of the most common pump technologies used by equipment designers: WOB-L piston: High pressure and vacuum capabilities relative to the compact size and light weight of the unit. Moderate to high air flows, depending on the design. Very efficient, especially compared with similarly sized diaphragm pumps.

By working with power sector engineers and operators, Edwards is able to challenge the limits of vacuum system design, creating solutions to meet the demands of increasingly challenging applications. The efficiency of steam turbines is an important part of electricity generation. Edwards’ liquid ring vacuum pumps play a vital role in maximising efficiency by removing excess air from the system. On exiting the turbine, steam is condensed either by a water or an air-cooled condenser, creating a vacuum inside the turbine and therefore increasing efficiency. To maintain this vacuum, air and other non-condensable gases (that leak into and build up within the condenser) must be extracted. Liquid ring vacuum pumps are used worldwide in this critical application.

  • Vacuum Pump SOP
    Vacuum Pump SOP Summary: This fact sheet talks about four main types of vacuum pumps (rotary vane vacuum pumps, diaphragm vacuum pumps, combination/hybrid vacuum pumps, and scroll vacuum pumps) that are used in low to medium vacuum applications, tips for minimizing the hazards when operating in the lab, when and how to use cold traps, and recommendations for using vacuum pumps with highly hazardous chemicals. • Use vacuum pumps with vacuum capacity appropriate to the application. Rotary vane and diaphragm pumps are used for most wet applications. Do not use aspirators. • Ensure apparatus is rated for vacuum level. • Always use a trap when using solvents or other volatile materials. • Follow all manufacturer’s guidance for maintenance, including oil changes, and operation. Main Types of Vacuum Pumps: Vacuum pumps are used in a wide variety of lab settings to remove air and other vapors from a vessel or system. Applications that use vacuum pumps include rotary evaporators, vacuum ovens, schlenk lines, drying manifolds, freeze-dryers, aspirations, desiccators, and filtration equipment. You may be exposed to hazardous chemicals and vapors if not using them properly. This fact sheet covers common types of vacuum pumps used in low to medium vacuum applications in the lab. Rotary Vane Vacuum Pumps: Rotary vane pumps are most commonly used. Rotary vane vacuum pumps reach deep ultimate vacuum levels (typically 10-2-10-4 Torr or 1-10-2 Pa) and have high displacement capacity, which make them an excellent choice for freeze drying applications. They work particularly well for aqueous solvent and samples with high boiling points.

  • Chapter 6: Mechanical Vacuum Pumps
    Las Positas College Vacuum Technology 60A & 60B Chapter 6: Mechanical Vacuum Pumps In this chapter we will review the principles of operation of several commonly used mechanical vacuum pumps, provide information on the performance and typical applications, and describe appropriate preventative maintenance techniques. This chapter also includes several laboratory procedures that are designed to aid in your understanding of mechanical vacuum pumps. Positive gas displacement pumps of one type or another have been used since 1640! Almost all of the very early pumps used liquid mercury within glass tubes and vessels to create a vacuum. For an excellent review of this early technology, read the History of Vacuum Science and Technology, edited by T.E. Madley and W.C Brown, published for the American Vacuum Society by the American Institute of Physics. Modern mechanical pumps may well be considered the workhorses of vacuum technology; they are simple in design, require little maintenance, are relatively inexpensive, and can operate for long periods of time without failure. Several mechanical vacuum pumps that we are aware of have operated continuously for fifteen years with only occasional oil changes! The range of pumping speeds for commercially available pumps runs from about 0.5 liters per second to over 300 liters per second. Mechanical vacuum pumps fall into two basic categories: reciprocating pumps, and rotary pumps. Further distinctions for mechanical pumps include: the number of stages (single stage or compound), the use of oil in a pump (pumps may be oil sealed or "dry"), and the means of driving the mechanics of a pump (direct drive or belt drive).
