startxref Note that different pump size/configurations are capable of handling different amounts of gas flow through the pump while maintaining vacuum, but this is a separate property from the base pressure achievable. RP?HBM1Hf^aPz=Z[ Together, the pumps form a so-called pump stand. Oil mist is produced in the pump housing.

Vacuum pumpsgenerate the vacuumin the vacuum chamber of the plasma system. The pumping mechanism is the steady depletion of gas molecules within the volume of the pump as they are deposited on the cold surfaces of the cryopump. While they can still be found in many semiconductor applications, oil-sealed rotary vane pumps have largely been supplanted in the industry by "dry" pumps owing to the fact that dry pumps offer less risk of oil contamination in the process (Figure 2). They are also used for non-corrosive/non-hazardous applications, surface analysis and sample preparation. Mechanical compression-expansion pumps are used in almost all systems to achieve base pressures of 10-4 - 10-3 Torr. Its market-leading oil retention means that the quality of the exhausted air is optimal, which contributes to employee well-being (as this air is often breathed). Significantly better performance against benchmarked oil-sealed and dry vane vacuum pumps. In it, there are sliders loaded by springs, which are pressed against the inner wall of the housing and slide along it. Rotary slide vane pumps are particularly well suited for our standard systems. In the world of vacuum systems, scroll pumps hold a valuable place as one of the few pumps that are traditionally employed in low (i.e. #qB 8`pX! 8FmL#j]RTb+|}s> &4:k#3/N H{W L,%+3N6?wJz78Ay2;7w5L=u 0000001362 00000 n 0000096195 00000 n Here they encounter another rotating blade that moves them towards another stator further down the pump and closer to the exhaust. The gas is thus compressed through a number of stages in the turbomolecular pump until it finally exits the turbomolecular pump and is drawn away by the backing mechanical pump. 2160 0 obj <> endobj Sustainable productivity due to built-in efficiency. During the regeneration cycle, the cryopump is isolated from the process chamber and its temperature is raised to room temperature or higher to convert all of the condensed material to the gas phase so that it may be pumped away. Choose products to compare anywhere you see 'Add to Compare' or 'Compare' options displayed. 0000096783 00000 n The rotary slide vane pump can produce limited pressure only. The gas trapped on the intake side is compressed until it exceeds the ambient pressure and the outlet valve on the discharge side opens. Due to its plug & play design, the EOSi Series assures an easy and fast installation which saves time and space. Pirani Thermal Conductivity Vacuum Gauge Physics, Compression-expansion of the gas (piston pumps, rotary pumps, Root's (dry) pumps), Drag by viscosity effects (vapor ejector pumps), Drag by diffusion effects (vapor diffusion pumps), Molecular drag (molecular drag or turbomolecular pumps), Physical or chemical sorption (sorption pumps, cryopumps and gettering processes). It also avoids oil spills on the factory floor, which commonly occurs with conventional oil-lubricated pumps.

Part of their attraction is that, being a dry pump, there is no risk of contamination, although to counter this significant characteristic, it must be acknowledged that they are intolerant to particles and, in addition, there is a potential of particle generation due to tip seal wear. For frequent use on the shop floor, however, we recommend to purchase a dry-running pump. The creation of a vacuum can be simply stated as the removal of gas molecules from a defined volume.

The pump is designed to ensure that the mean free path of molecules in the gas within the pump is greater than the distance between the rotor disc blades and the stator disc blades. Based on the well-known and durable plug-and-play design principles, these vacuum pumps have been designed by vacuum engineers to deliver peak performance at operating pressures commonly found in industrial applications. The first pump (e.g. One spiral is fixed whilst the other (the orbiter) moves eccentrically without rotating, against the other. The main working parts of a scroll pump consist of two co-wound spiral-shaped scrolls contained within a vacuum-housing, with an exit valve at the centre of the scroll assembly. This process is repeated twice per full revolution for each of the two pistons.

high initial cost, their operating costs are low because they do not require oil (which also makes them environmentally friendly). Rotary vane pumps are typically used in applications requiring low or medium vacuum operation and come in single and two-stage pumping configurations; two-stage pumps are capable of achieving lower base pressures. The pump can be selected individually to match the chamber volume and desired process time. Furthermore, scroll pumps are available with frequency converters designed so that their performance throughout the world and, in addition, three-phase electronic-free variants of scroll pumps are available for use in radiation and high-magnetic field environments. They can also cope with particle, condensation or corrosion by-products. It provides a perfectly clean approach (i.e., no oil or other contaminants that might backstream into the process chamber) for the generation of high vacuum conditions between 10-3 and 10-9 Torr. Dry pumps are also compression-expansion pumps; however, they employ different mechanisms to create this action. All mechanical compression-expansion pumps are limited in the base vacuum pressure that they can achieve, with values of about 0.1-1 millitorr (~0.1-1 x 10-3 mbar) being typical. :'R1=3?gG-Y:9SW whc-z [|M^SNtD`9qpqViU!!h%=1HS'!

Gas enters the (outside) open end of the spirals and, as one of the spirals orbits, gas is trapped between the scrolls and transported towards the centre as the void occupied by the gas is squeezed and transported between the two spirals. service@plasma.com. Vacuum pumps can be based on a number of different principles: In practice, within the semiconductor industry, the reader will primarily encounter mechanical pumps that operate on the compression-expansion principle, molecular drag pumps such as turbopumps, and physical sorption pumps such as cryopumps. This oil is non-combustible. However, using these pumps often with corrosive gases reduces their useful life. Potential-free connection through 2 changeover contacts for pump protection circuit. The new patent inlet control valve provides modulating vacuum control in conjunction with the VSD drive to minimise energy consumption. 0000033787 00000 n It can be seen that much higher pumping speeds are achieved at low pressures when the pump/blower combination is employed. Roots pumps, also named Roots-type blowers, are rotary lobe pumps in which two symmetrically designed rotary lobes rotate in the opposite direction in the feed housing. x3T0 BCSc=s3c=s#S\B.C.HIn& Nagolder Strae 61 D-72224 Ebhausen/Germany +49 (0)7458 99931 - 0 info@plasma.com, Special and inline systems/fully automated systems, Production plasma systems / Inline systems. In practice, industrial vacuums are produced using different kinds of vacuum pumps. POM parts, silicone rubber or moist parts). This characteristic means that prolonged times are needed to achieve base pressure when using only a mechanical rotary vane, screw or claw pump. An in-depth understanding of the creation of vacuum requires consideration for physical characteristics such as gas viscosity, flow type (degree of turbulence), the thermal conductivity of the gas, and gas diffusion properties.
