The reason is these drying process occur in the rough vacuum level (above 30 Torr (40 mbar)) and these vane pumps are not designed for high pressure operation.Set-ups for Lab ApplicationsProper vacuum system set-up in lab applications does reduce pump maintenance which lowers cost and increases user productivity. Proper vacuum system set-ups consist of the lab appliance, tubing, vacuum pump, and normally cold or liquid trap. Failure to use or maintain the appropriate trap will result in a shortened service life of the pump.1Maxima and Isotemp™ are registered trademarks of Fisher Scientific.。

A balancer is provided in the outer circumferentialsurface of the rotor so as to face the inside of the gas passageway. A balancer main body is supported against the outer circumferential surface of a rotor through a fragile portion that is weak with respect to corrosive gasses, the fragile portion of the balancer is damaged by corrosion before any corrosive gas influence appears in rotor blades or the rotor, and the balancer falls off, thus forcibly causing an unbalanced state to appear in the rotor. The balancer thus possesses a function for balancing the rotor and a corrosion detecting function. The unbalanced state of the rotor is then detected by a sensor, and damages to the vacuum pump itself and to the peripheral apparatuses can be prevented by stopping the pump.申请人：MAEJIMA YASUSHI,SAKAGUCHI YOSHIYUKI更多信息请下载全文后查看。

Fast rotating vacuum pumps could be combined together with fast rotating high vacuum pumps, for example turbomolecular pumps, to form single shaft vacuum pumps which can compress from high vacuum or ultra high vacuum to atmospheric pressure. For this purpose, the inventive vacuum pump (10) has a suction stage (12) and a centripetal compressor stage (21) placed thereafter in line, with radially extending compression chambers (33), the outlet cross section of which is smaller than 0.4 times the cross section of the inlet. The centripetal compressor is not a displacement machine and can therefore be operated at high rotational speeds and can compress gases from pre-vacuum pressures to atmospheric pressure at high rotational speeds. This creates the possibility of generating a high vacuum or ultra high vacuum with only one single shaft fast rotating vacuum pump.申请人：GIEBMANNS, Wolfgang地址：DE,DE国籍：DE,DE代理机构：EBERLEIN, Jasper更多信息请下载全文后查看。
