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 ...
Edwards has over 3,200 full-time employees and 500 temporary workers operating in approximately 30 countries worldwide engaged in the design, manufacture and support of high technology vacuum and ...
A vacuum pump is a type of pump device that draws gas particles from a ... Examples of such pumps are Edwards EPX [19 ... Venturi vacuum pump (10 to 30 kPa)
Most general pumps can increase as well as decrease the pressure of a gas; however, this category contains pumps that are usually exclusively used to decrease pressure. Wikimedia Commons has media related to Vacuum pumps .
A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [ 1 ] [ 2 ] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface.
An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
