Air Pumps are Used in Vacuum Systems
One summer when I was eight or so I remember waking up morning after morning to a jackhammer breaking and splitting the black surface of the road in front of my house one summer. The noise was nearly unbearable and shook me to the core; needless to say, I could never get back to sleep. What makes that awful noise and how can the man operating it handle it? I have since learned that an air pump assists in making that awful noise and the man operating it can handle it with the use heavy duty ear plugs.
Air pumps force air into or out of something at moderate to high pressures. They differ from fans in that fans simply move air, not force it like air pumps, or other gases between two different spaces at a lower pressure. Air pumps are especially useful in vacuum systems. The air pumps must be specifically designed to remove atmosphere from an enclosure and prevent it from returning to it. One or more fans with intake and outlet pipes, seals and a power source are all features that are required of an air pump to help equalize the natural tendency of differing air pressures.
Vacuum systems can differ greatly in size, construction, degree of vacuum, etc. Therefore, the air pump must accommodate to these specifications to maximize its effectiveness. It can range from a single, small fan to multiple fans in thick steel or a different kind of strong metal enclosure. Air vacuum pumps are necessary and required in many types of industrial manufacturing, applications and industries including: semiconductor fabrication, medical technology, surgery, medical instruction and research, instrumentation design, dentistry and biological and chemical laboratories.
Vacuum pumps are versatile device that can be used in a multitude of industries and can often be life saving when used in medical settings or biological and chemical research.
