A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. [44] A vacuum may be used to power, or provide assistance to mechanical devices. In hybrid and diesel engine motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce a vacuum.
A centrifugal evaporator often comprises a vacuum pump connected to a centrifuge chamber in which the samples are placed. Many systems also have a cold trap or solvent condenser placed in line between the vacuum pump and the centrifuge chamber to collect the evaporated solvents. The most efficient systems also have a cold trap on the pump exhaust.
After the war, some of the inventions found new applications. The first transistor radio was released in 1954, and its manufacturing process made use of vacuum pumps. [43] The first integrated circuit or “chip” came to the market at the end of the 1950s, and vacuum pumps again played an important role in their production. These early ...
A vacuum bell jar is placed on a base which is vented to a hose fitting, that can be connected via a hose to a vacuum pump. A vacuum is formed by pumping the air out of the bell jar. The lower edge of a vacuum bell jar forms a flange of heavy glass, ground smooth on the bottom for better contact. The base of the jar is equally heavy and ...
A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low- pressure environment within the chamber, commonly referred to as a vacuum . A vacuum environment allows researchers to conduct physical experiments or to test mechanical devices which must operate in outer space (for example ...
