    摘要： A multiple-type pump has a simple construction and superior durability. The multiple-type pump has the capacity to perform air evacuation at high velocities in the atomospheric pressure zone to high vacuum zone range. The multiple-type pump includes: a screw type pump air transfer portion arranged at a downstream portion of the outer surface of a rotor and has a plurality of screw threads and screw grooves with a width of 5 mm or more; a turbo-molecular type pump air transfer portion arranged at an upstream portion and has a plurality of vanes and air transfer grooves; vanes having vane widths of 3 mm or less at the upstream edge, and formed so that the downstream edge is continuous with the upstream edge of the screw threads; a downstream edge of the base of the air transfer grooves formed so as to be continuous with the upstream edge of the base of the screw grooves. The turbo-molecular type pump air transfer portion takes the air brought in from the upstream edge at the time of rotation, compresses it and transfers it to the upstream edge of the screw type pump air transfer portion.

    摘要： A multiple-type vacuum pump has a simple construction and superior durability. The multiple-type vacuum pump has the capacity to perform air evacuation at high velocities in the low to high vacuum zone range. The multiple-type vacuum pump includes: a screw type pump air transfer portion arranged at a downstream portion of the outer surface of a rotor and has a plurality of screw threads and screw grooves with a width of 5 mm or more; a turbo-molecular type pump air transfer portion arranged at an upstream portion and has a plurality of vanes and air transfer grooves; vanes having vane widths of 3 mm or less at the upstream edge, and formed so that the downstream edge is continuous with the upstream edge of the screw threads; a downstream edge of the base of the air transfer grooves formed so as to be continuous with the upstream edge of the base of the screw grooves. The turbo-molecular type pump air transfer portion takes the air brought in from the upstream edge at the time of rotation, compresses it and transfers it to the upstream edge of the screw type pump air transfer portion.

    摘要： In the case of a vacuum pump, having a screw groove, of the present invention, a rotor is disposed inside a stator with an extremely small clearance provided in-between, under which condition the rotor is designed to rotate at a high speed. The upper and lower end faces of the aforementioned stator are supported with sliding members interposed in-between, thereby enabling the stator to perform sliding rotation. Between the stator and a pump housing is provided a clearance r. In the event that stress corrosion cracking occurs to the rotor, then part of the rotor comes into contact with the stator, thereby causing the stator to be deformed radially outward. Even when such deformation takes place, the stator rotates together with the rotor, since the clearance r is provided on the outside periphery of the stator, with the result that consequent rotational friction causes the rotor to decelerate. Therefore, even when stress corrosion cracking occurs to the rotor, it is possible to prevent the housing from being fractured.

    摘要翻译： 在具有本发明的螺旋槽的真空泵的情况下，转子设置在定子内部，间隙设置在其间具有非常小的间隙，在该条件下，转子被设计成高速旋转。 上述定子的上端面和下端面由插入其间的滑动构件支撑，从而使得定子能够执行滑动旋转。 在定子和泵壳之间设有间隙r。 在转子发生应力腐蚀开裂的情况下，转子的一部分与定子接触，从而使定子径向向外变形。 即使发生这种变形，因为定子与转子一起旋转，因为间隙r设置在定子的外周，结果是随之而来的旋转摩擦使转子减速。 因此，即使当转子发生应力腐蚀开裂时，也可以防止壳体断裂。
