Vacuum pumps in plasma technology

Special vacuum pumps have been developed to work with corrosive gases (CF4 / O2, SF6, ). The rotary slide vane pumps described below are suitable for many applications. However, using these pumps often with corrosive gases reduces their useful life. Usually, one pump of this type is

Vacuum pump Wikipedia

A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.

Vacuum pump Wikipedia

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

Vacuum Pump / Blower Basics ORION Machinery Co., LTD.

A single-stage pump where a pair of screw-shaped rotors are contactlessly rotated in opposite directions at a constant speed in order to draw in air, which is compressed and then blown out. Vacuum Units (Gauge Pressure and Absolute Pressure) Vacuum units are given in absolute pressure or gauge pressure. Absolute pressure is zero-referenced to a perfect vacuum, and gauge pressure is zero

Vacuum Technology for Chemical and Pharmaceutical

Dry Screw Vacuum Pumps. Dry screw vacuum technology is also very widely used in the chemical and pharmaceutical industries. However, this is relatively new compared to liquid ring technology. In the 1990s, Busch launched the first dry screw vacuum pump on the market, the COBRA AC. The major difference compared to the liquid ring vacuum pump described above is that screw vacuum pumps

Vacuum technology Britannica

The gas is trapped between the impellers and the stator wall and transferred from the high vacuum to the fore vacuum side of the pump. The mechanical booster must be backed by another pump in series when working in its normal pressure range. The most frequently used type of forepump is the oil-sealed rotary pump. Typically, the mechanical booster is employed for pumping vacuum-melting furnaces, in an
