Fore vacuum pumps - Leybold Guide

Fore vacuum pumps - Leybold Guide

Fore vacuum pumps always work against atmospheric pressure or a similarly high pressure into an exhaust pipe. They are used in almost every vacuum system and are a prerequisite for achieving low pressures by the use of high-vacuum pumps. Depending on the operating principle and design pumping speed and ultimate pressure vary significantly.

Ultra-high vacuum - Wikipedia

Ultra-high vacuum - Wikipedia

Ultra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascal (10 −7 pascal, 10 −9 m bar, ~10 −9 torr).UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the .

Types of Pumps. Now, let's move on to vacuum pumps. We can sort them into 2 broad categories: Positive Displacement. A positive displacement pump moves a fixed amount of fluid and then guiding it into a discharge pipe. This allows the pumps to produce a continuous flow at a set speed regardless of the discharge pressure. Centrifugal

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from .
