Liverpool Hydraulic Power Company
Liverpool's Hydraulic Power Company were the operators of a public hydraulic power network supplying energy across the city of Liverpool, England, via a system of high-pressure water pipes from two pumping stations. The system was the third public system to be built in England, opening in 1888. It expanded rapidly, but gradually declined as electric power become more readily available. The pumping station was converted to electric operation in 1960, but the system was turned off in 1971. One of the pump sets was salvaged and presented to the Liverpool Museum. History The Liverpool Hydraulic Power Co obtained Acts of Parliament in 1884 and 1887, to allow it to construct a hydraulic power network under the streets of Liverpool. The system was operational by 1888, and was the third such undertaking in Britain, following the opening of the first system in Hull in 1877, and the second in London in 1883. At its inception, it supplied pressurised water at to its customers through aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool
Liverpool is a city and metropolitan borough in Merseyside, England. With a population of in 2019, it is the 10th largest English district by population and its metropolitan area is the fifth largest in the United Kingdom, with a population of 2.24 million. On the eastern side of the Mersey Estuary, Liverpool historically lay within the ancient hundred of West Derby in the county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of the newly-created Lancashire County Council in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Accumulator
A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas.Although liquids are generally considered to be practically incompressible, gases may be compressed and this compressed gas is a convenient energy store. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type. Types of accumulators Towers The first accumulators for William Armstrong's hydraulic dock machinery were simple raised water towers. Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Manchester Hydraulic Power
Manchester's Hydraulic Power system was a public hydraulic power network supplying energy across the city of Manchester via a system of high-pressure water pipes from three pumping stations from 1894 until 1972. The system, which provided a cleaner and more compact alternative to steam engines, was used to power workshop machinery, elevator, lifts, crane (machine), cranes and a large number of cotton baling presses in warehouses as it was particularly useful for processes that required intermittent power. It was used to wind Manchester Town Hall clock, pump the organ at Manchester Cathedral and raise the safety curtain at Manchester Opera House in Quay Street. A large number of the lifts and baling presses that used the system had hydraulic packings manufactured by John Talent and Co.Ltd. who had a factory at Ashworth Street, just off the Bury New Rd. close to the Salford boundary. Manchester Corporation opened its first pumping station in 1894, following pioneering schemes in Ki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Hydraulic Power Company
The London Hydraulic Power Company was established in 1883 to install a hydraulic power network in London. This expanded to cover most of central London at its peak, before being replaced by electricity, with the final pump house closing in 1977. History The company was set up by an Act of Parliament (the London Hydraulic Power Company Act 1884), sponsored by railway engineer Sir James Allport, to install a network of high-pressure cast iron water mains under London. It merged the Wharves and Warehouses Steam Power and Hydraulic Pressure Company, founded in 1871 by Edward B. Ellington, and the General Hydraulic Power Company, founded in 1882. The network gradually expanded to cover an area mostly north of the Thames from Hyde Park in the west to Docklands in the east. The system was used as a cleaner and more compact alternative to steam engines, to power workshop machinery, lifts, cranes, theatre machinery (including revolving stages at the London Palladium and the London Colis ...

Hathorn Davey
Hathorn Davey was a British manufacturer of steam engines, based in Leeds. The Sun foundry was established in 1846 and made railway engines and pumping machinery until 1870. The premises were taken over in 1872 by Hugh Campbel, Alfred Davis and John Hathorn. They were joined by Henry Davey in 1873 and traded as Hathorn, Davey & Co from 1880. The partnership was converted to a limited company in 1901. They made marine engines and pumps as well as their pumping engines for mines and waterworks. The pumping engine built for the Mersey tunnel in 1881 was described at the time as the most powerful in existence. The firm was taken over by Sulzer (manufacturer), Sulzers in 1936. The premises closed in late 1981 when Sulzers moved to a new site. The horizontal compound differential pumping engine This was one of their more successful engines.

Mechanical Stoker
A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse. There are three types: the over feed, the under feed and the cross feed. The over feed delivers coal on to the top of the coals already in the furnace in the manner of a human working a shovel. The under feeder pushes fresh coal into the bottom of the furnace and then advances it upwards so that it mixes with the burning coal above. The mechanical means used are, depending on design, combinations of the screw feed, the conveyor belt, the bucket chain, the paddle and the ram. Steam jets from the boiler or a mechanical catapult may also be used to throw coal into the far reaches of the furnace. Use in steam locomotives The confined working c ...

Hydraulic Power Network
A hydraulic power network is a system of interconnected pipes carrying pressurized liquid used to transmit mechanical power from a power source, like a pump, to hydraulic equipment like lifts or motors. The system is analogous to an electrical grid transmitting power from a generating station to end-users. Only a few hydraulic power transmission networks are still in use; modern hydraulic equipment has a pump built into the machine. In the late 19th century, a hydraulic network might have been used in a factory, with a central steam engine or water turbine driving a pump and a system of high-pressure pipes transmitting power to various machines. The idea of a public hydraulic power network was suggested by Joseph Bramah in a patent obtained in 1812. William Armstrong began installing systems in England from the 1840s, using low-pressure water, but a breakthrough occurred in 1850 with the introduction of the hydraulic accumulator, which allowed much higher pressures to be used.
