  2. Cheng rotation vane - Wikipedia

    en.wikipedia.org/wiki/Cheng_rotation_vane

    A fluid flow conditioning device, the cheng rotation vane (CRV) is a stationary vane [1] fabricated within a pipe piece as a single unit and welded directly upstream of an elbow before the pump inlet, flow meters, compressors, or other downstream equipment.

  3. Rotary vane pump - Wikipedia

    en.wikipedia.org/wiki/Rotary_vane_pump

    An eccentric rotary vane pump Another eccentric rotary-vane pump design. Note that modern pumps have an area contact between rotor and stator (and not a line contact). 1. pump housing 2. rotor 3. vanes 4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In ...

  4. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    A critical element in vane pump design is how the vanes are pushed into contact with the pump housing, and how the vane tips are machined at this very point. Several type of "lip" designs are used, and the main objective is to provide a tight seal between the inside of the housing and the vane, and at the same time to minimize wear and metal-to ...

  5. Rotary feeder - Wikipedia

    en.wikipedia.org/wiki/Rotary_feeder

    Rotary airlock; The basic use of the rotary airlock feeder is as an airlock transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure and suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to ...

  6. Liquid-ring pump - Wikipedia

    en.wikipedia.org/wiki/Liquid-ring_pump

    Liquid-ring pumps are typically used as vacuum pumps, but can also be used as gas compressors.The function of a liquid-ring pump is similar to a rotary vane pump, with the difference being that the vanes are a rigid part of the rotor and churn a rotating ring of liquid to form the compression-chamber seal.

  7. Leybold GmbH - Wikipedia

    en.wikipedia.org/wiki/Leybold_GmbH

    In 1863, Ernst Leybold took over the company completely, but resold it in 1870. The company name lived on for some time, however, as E. Leybold's Nachfolger (E. Leybold's Successor). The company divested the pharmaceutical sector to focus on propaedeutic and teaching materials, initiating the serial production of vacuum pumps as of 1906.

  8. Rotary-screw compressor - Wikipedia

    en.wikipedia.org/wiki/Rotary-screw_compressor

    Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.

  9. Impact wrench - Wikipedia

    en.wikipedia.org/wiki/Impact_wrench

    Compressed air is the most common power source for impact wrenches, [citation needed] providing a low-cost design with the best power-to-weight ratio.A normal vane motor is almost always used, usually with four to seven vanes, and various lubrication systems, the most common of which uses oiled air, while others may include special oil passages routed to the parts that need it and a separate ...
