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 ...
A more sophisticated system called the vane gear was later devised, it relied on a small vane or airfoil driving the main rudder via an adjustable system of clockwork gears. It was very similar to the later vane driven autopilots seen on transatlantic yachts such as Blondie Hasler 's self steering rudder.
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.
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 ...
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.
In 1994, Degussa sold Leybold to the Swiss Oerlikon Bührle Group, which combined Leybold with the Balzers AG, which was already in their possession, to form the Balzers and Leybold Group. The merger of these companies resulted in the world's largest vacuum and surface technology company with around 6 500 employees, generating sales of DEM 1.8 ...
Several companies manufacture and supply rotating-vane variable-geometry turbochargers, including Garrett, BorgWarner, and Mitsubishi Heavy Industries. This design is mostly limited to small engines and light-duty applications (passenger cars, race cars and light commercial vehicles). The main supplier of sliding-vane VGTs is Holset Engineering ...
BPV – back pressure valve (goes on the end of coiled tubing a drill pipe tool strings to prevent fluid flow in the wrong direction) BQL – B/QL log; BRPLG – bridge plug log; BRT – below rotary table (used as a datum for depths in a well) BS – bend stiffener; BS – bumper sub; BS – booster station
