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 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 ...
With these acquisitions, Vickers could now produce a complete selection of products, from ships and marine fittings to armour plate and a whole suite of ordnance. In 1901 the Royal Navy's first submarine, Holland 1, was launched at the Naval Construction Yard. In 1902 Vickers took a half share in the famous Clyde shipyard John Brown & Company.
The Vickers VR180 Vigor was a British crawler tractor, built from 1951 to 1958 by Vickers-Armstrongs. Since the 1920s, the company gained substantial experience in the design and construction of tanks and continuous track vehicles. After the war they developed a civilian crawler tractor that could be sold for use in peacetime reconstruction work.
Single-stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 47 millibars (4.7 kPa), and two-stage pumps can produce vacuum to 25 torr, assuming air is being pumped and the ring-liquid is water at 15 °C (59 °F) or less. Dry air and 15 °C sealant-water temperature is the standard performance basis, which most manufacturers use for ...
Vickers was a pioneer in producing airliners, early examples being converted from Vimy bombers. Post-WWII, Vickers went on to manufacture the piston-engined Vickers VC.1 Viking airliner, the Viscount and Vanguard turboprop airliners and (as part of BAC) the VC10 jet airliner, which was used in RAF service as an aerial refuelling tanker until 2013.
The Vickers plant in Cross Gates, Leeds, 2009. In 1980, Vickers plc acquired Rolls-Royce Motors.This was not Vickers' first involvement with Rolls-Royce. In 1966, Rolls-Royce Limited (the original aero-engine and motor car company) acquired Bristol Aeroplane for its Bristol Siddeley engine business, but declared it had no interest in Bristol's 20% shareholding in BAC; Vickers Armstrong and ...
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators , steam turbines , switchgear , transformers , electronics and ...
