    摘要： Provided is a coupling structure for vacuum exhaust devices each including a pump chamber and a casing that demarcates the pump chamber. The coupling structure includes a first end surface formed on a first side of the casing, and a second end surface formed on the second side of the casing, the second side being the opposite side of the first side. The casing of a first vacuum exhaust device and the casing of a second vacuum exhaust device among a plurality of vacuum exhaust devices are arranged to be directly superposed on each other such that the first end surface provided to the first vacuum exhaust device and the second end surface provided to the second vacuum exhaust device come into contact with each other. By fastening the first end surface and the second end surface, the first vacuum exhaust device and the second vacuum exhaust device are connected to each other such that gas can flow between the casing of the first vacuum exhaust device and the casing of the second vacuum exhaust device.

    摘要： The disclosure generally relates to pump assembly that includes a rotary vane vacuum pump. The pump assembly is controlled using a controller and may be moved through manipulation of a robotic arm segment of the pump assembly and a reel and cable segment of the pump assembly. The vacuum pump includes a motor and rotor each offset from the center axis of the body of the vacuum pump. Vanes that are longer than the diameter of the rotor slide within cavities of the rotor and, as the rotor turns, create a vacuum in the vacuum generating chamber of the pump. A bypass groove on the rotor limits thermal expansion and a biasing spring maintains a critical distance between the rotor and an air intake plate to maintain proper vacuum in the vacuum generating chamber.

    摘要： A vacuum pump (10) has a pump casing (54) including pump chambers (50a-50f) held in fluid communication with each other and arrayed in a longitudinal direction thereof, an inlet port (52a) and an outlet port (52b), a rotational shaft (58) rotatably supported at opposite ends thereof and extending in the longitudinal direction of the pump casing (54), and rotors (60a-60f) housed in the pump chambers (50a-50f) and coupled to the rotational shaft (58). The pump casing (54) includes a first thermally conductive member (72) extending parallel to the rotational shafts (58) substantially the full length of the pump casing (54) in the longitudinal direction thereof, and a second thermally conductive member (74) positioned near an end of the first thermally conductive member (72) at the outlet port (52b) and extending in a transverse direction of the pump casing (54).

    摘要： A method of pumping a gas stream containing a condensable species and a light gas and an apparatus therefore, the method comprising the steps of conveying the gas stream to a multistage vacuum pump comprising an inlet stage and an exhaust stage downstream from the inlet stage, and adding to the gas stream upstream of or at the inlet stage a purge gas heavier than said light gas to both inhibit migration of the light gas from the exhaust stage towards the inlet stage and to inhibit condensation of the condensable species within the pump.
