摘要： PROBLEM TO BE SOLVED: To provide a multistage dry-sealed vacuum pump in which even though inlet pressure of a gas to be evacuated is high, a high pumping-speed is maintained and low power-consumption can be achieved.
SOLUTION: The multistage dry-sealed vacuum pump comprises an intermediate discharge pipe 30 of which one end is allowed to communicate with a discharge port 28 of a 3rd-stage pump chamber 10, and the other end is opened to the outside, and a check valve 32 which is provided midway in the intermediate discharge pipe 30, and has the atmospheric side as forward direction. In the case when suction pressure of the gas sucked from a main suction port 3 is comparatively high, e.g. discharge pressure of the 3rd-stage pump chamber 10 is higher than the atmospheric pressure, the check valve 32 is opened to release the pressure to the atmosphere from the intermediate discharge pipe 30. Thus, the suction pressure of a 4th-stage pump chamber 11 does not become higher than the atmospheric pressure. Consequently, even though the gas is sucked/discharged at a comparatively high suction pressure, the pumping speed is not decreased.

摘要翻译：要解决的问题：为了提供即使被抽空气体的入口压力高的多级干式密封真空泵，保持高的泵送速度并且可以实现低的功率消耗。解决方案：多级干式密封真空泵包括中间排出管30，其一端与第三级泵室10的排出口28连通，另一端向外开放，以及设置在中间排出管30中途的止回阀32，其大气侧为正向。在从主吸入口3吸入的气体的吸入压力比较高的情况下，第3级泵室10的排出压力高于大气压，止回阀32打开，从中间排出管30释放向大气的压力。因此，第4级泵室11的吸入压力不会变得高于大气压力。因此，即使在比较高的吸入压力下吸入/排出气体，也不会降低泵送速度。版权所有（C）2005，JPO＆NCIPI
