摘要： A screw pump includes a casing having inlet and outlet ports and a pump rotor rotatably mounted in the casing and having screw threads communicating with said inlet and outlet ports. The pump rotor is rotated by a reversible speed-controllable motor, typically a DC brushless motor, mounted in the casing to deliver a liquid such as a chemical solution from the inlet port through a liquid passage defined by the screw threads to the outlet port.

摘要： A vacuum pumping apparatus is presented having a Peltier element based device to provide a dual role of cooling for bearings/drive-motor and heating for sections prone to depositing reaction products. A housing (7) having the bearing and motor sections is provided with a Peltier element based device (20) to absorb the waste heat generated in the bearings and the drive motor, and transfer the waste heat to another section (17) of the apparatus to be released. The released heat may be used to heat that section of the device to facilitate vacuum processing, wherein reaction products are prone to sublime and deposit.

摘要： A magnetic bearing unit is disclosed which comprises a rotor supported in a radial direction by magnetic effects generated by permanent magnets arranged within a passive radial magnetic bearing and supported in an axial direction by an actively-controlled axial magnetic bearing. The unit also comprises a movable member arranged between the stator and rotor, and the passive magnetic member is arranged between the movable member and the rotor. At least first and second pairs of axially opposing faces are provided on the stator and the movable member respectively. A biasing means is in functional association with the movable member for forcing the movable member to shorten a spacing between the first pair of opposing faces. The first pair of opposing faces is formed with a recess having a curved cross sectional shape on each of the opposing faces, and a plurality of balls having a radius not more than a radius of the recess are disposed in the recess. The second pair of opposing faces are bridged with a damping member made of an elastic material. The resulting bearing unit in such a compressive state can be used in any orientation without causing any operational problems such as those encountered when the conventional magnetic bearing is used in a horizontal orientation. The unit is easy to control and produces stable smooth operation in radial and axial directions at all times.
摘要翻译：公开了一种磁轴承单元，其包括通过由被动径向磁轴承中布置的永磁体产生的并且通过主动控制的轴向磁轴承沿轴向支撑的磁力作用沿径向方向支撑的转子。该单元还包括设置在定子和转子之间的可动构件，并且被动磁构件设置在可动构件和转子之间。至少第一和第二对轴向相对的面分别设置在定子和可动件上。偏压装置与可动件功能相关联，用于迫使可动件缩短第一对相对面之间的间距。第一对相对面形成有在每个相对面上具有弯曲横截面形状的凹部，并且具有半径不大于凹部半径的多个球设置在凹部中。第二对相对面与由弹性材料制成的阻尼构件桥接。所得到的轴承单元处于这种压缩状态，可以以任何方向使用，而不会引起任何操作问题，例如当常规磁性轴承以水平方向使用时所遇到的问题。该单元易于控制，始终在径向和轴向方向均匀平稳运行。
