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, lifts, 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. [1]

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.

Manchester City and metropolitan borough in England

Manchester is a city and metropolitan borough in Greater Manchester, England, with a population of 545,500 as of 2017. It lies within the United Kingdom's second-most populous built-up area, with a population of 3.2 million. It is fringed by the Cheshire Plain to the south, the Pennines to the north and east, and an arc of towns with which it forms a continuous conurbation. The local authority is Manchester City Council.

Steam engine Heat engine that performs mechanical work using steam as its working fluid

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine.

Manchester Corporation opened its first pumping station in 1894, following pioneering schemes in Kingston upon Hull and London. The scheme was a success and additional pumping stations to cope with the demand for power were added in 1899 and 1909. Modernisation started in the 1920s, when the original steam pumps were replaced by electric motors at two pumping stations. The greatest volume of water was supplied in the 1920s, although the length of the water mains continued to increase until 1948. Usage started to decrease in the 1930s, and the first pumping station closed in 1939. By the 1960s, there were serious concerns about the state of some of the equipment and corrosion in the high-pressure mains, and in 1968 the corporation announced its intent to switch the system off, which it did at the end of 1972.

Kingston upon Hull City and unitary authority in England

Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, 25 miles (40 km) inland from the North Sea, with a population of 260,700 (mid-2017 est.). Hull lies east of Leeds, east southeast of York and northeast of Sheffield.

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.

The grade II listed pumping station built in Baroque style at Water Street has a new life as part of the People's History Museum, while one of its pump sets has been restored and is displayed at the Museum of Science and Industry, where it is part of a larger display about hydraulic power.

Baroque architecture building style of the Baroque era

Baroque architecture is the building style of the Baroque era, begun in late 16th-century Italy, that took the Roman vocabulary of Renaissance architecture and used it in a new rhetorical and theatrical fashion, often to express the triumph of the Catholic Church. It was characterized by new explorations of form, light and shadow, and dramatic intensity. Common features of Baroque architecture included gigantism of proportions; a large open central space where everyone could see the altar; twisting columns, theatrical effects, including light coming from a cupola above; dramatic interior effects created with bronze and gilding; clusters of sculpted angels and other figures high overhead; and an extensive use of trompe-l'oeil, also called "quadratura," with painted architectural details and figures on the walls and ceiling, to increase the dramatic and theatrical effect.

The People's History Museum in Manchester, England, is the United Kingdom's national centre for the collection, conservation, interpretation and study of material relating to the history of working people in the UK. It is located in a grade II-listed, former hydraulic pumping station on the corner of the Bridge Street and Water Street designed by Manchester Corporation City Architect, Henry Price.

History

While Joseph Bramah had registered a patent for the distribution of high-pressure water via a ring main at the London Patent Office on 29 April 1812, [2] and engineer William Armstrong had installed hydraulic systems for single customers from the 1840s, [3] the first installation of a public hydraulic power network became operational in Kingston upon Hull in 1876. Edward B. Ellington was responsible, and created the General Hydraulic Power Company, from which developed the London Hydraulic Power Company. [4] With the technology tested, and Ellington's model of marketing hydraulic power as a public utility having proved successful, Manchester Corporation obtained an act of Parliament authorising it to build a network to distribute hydraulic power to the city in 1891. [5]

Joseph Bramah British engineer

Joseph Bramah, born Stainborough Lane Farm, Stainborough, Barnsley Yorkshire, was an English inventor and locksmith. He is best known for having invented the hydraulic press. Along with William George Armstrong, he can be considered one of the two fathers of hydraulic engineering.

A patent office is a governmental or intergovernmental organization which controls the issue of patents. In other words, "patent offices are government bodies that may grant a patent or reject the patent application based on whether the application fulfils the requirements for patentability."

William Armstrong, 1st Baron Armstrong English inventor, scientist, engineer, industrialist

William George Armstrong, 1st Baron Armstrong was an English industrialist who founded the Armstrong Whitworth manufacturing concern on Tyneside. He was also an eminent scientist, inventor and philanthropist. In collaboration with the architect Richard Norman Shaw, he built Cragside in Northumberland, the first house in the world to be lit by hydroelectricity. He is regarded as the inventor of modern artillery.

The corporation had the advantage over a private company in that it did not have to apply for permission to dig up the streets to install the network of high-pressure water mains. The pumping station was situated on Whitworth Street West, between Oxford Road railway station and the Rochdale Canal. Its working pressure was set at 1,120 pounds per square inch (77 bar), much higher than the 700 pounds per square inch (48 bar) of the London system, because it was expected that much of the power would be used for baling cotton, and the extra pressure was dictated by the design of existing baling equipment. [6] Pressure was supplied by six triple-expansion steam engines, rated at 200 hp (150 kW) each, and was maintained by two hydraulic accumulators, with pistons of 18-inch (460 mm) diameter, a stroke of 23 feet (7.0 m), and loaded with 127 tonnes. The equipment was supplied by Ellington's company. [7] Installation was completed by 1894, and by 1895 there were 12 miles (19 km) of hydraulic pipes under the city streets, providing power for 247 machines. [6]

Manchester Oxford Road railway station Manchester, Greater Manchester, M1

Manchester Oxford Road railway station is a railway station in Manchester, England, at the junction of Whitworth Street West and Oxford Street. It opened in 1849 and was rebuilt in 1960. It is the second busiest of the four stations in Manchester city centre.

Rochdale Canal

The Rochdale Canal is a navigable broad canal in Northern England, between Manchester and Sowerby Bridge, part of the connected system of the canals of Great Britain. Its name refers to the town of Rochdale, in Greater Manchester, through which it passes.

A hydraulic accumulator is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure that is applied by an external source. The external source can be a spring, a raised weight, or a compressed gas. 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.

Demand was high, and a second pumping station commenced operation on 6 July 1899. It was constructed at Pott Street in Ancoats, close to the Rochdale Canal, and had four pumping engines and two accumulators. The number of engines was increased to seven, six of 210 hp (160 kW) and one of 350 hp (260 kW). [8] A third pumping station was soon required and was constructed between Water Street and the River Irwell. It had two accumulators, and six steam engines. Coal for the engines was delivered by boat, and it began operating on 14 October 1909. Although all three pumping stations were situated beside waterways, its water supply was obtained from boreholes. The borehole at Whitworth Street was 613 feet (187 m) deep, and water at all three was raised by compressed air delivery systems, which lasted until 1948, when they were superseded by submersible pumps. [9] By the 1930s, the system had grown to 35 miles (56 km) of pipes working some 2400 machines. [10]

Ancoats is an area of Manchester in North West England, next to the Northern Quarter, the northern part of Manchester city centre.

River Irwell river in Lancashire, United Kingdom

The River Irwell is a 39-mile (63 km) long river which flows through the Irwell Valley in North West England. Its source is at Irwell Springs on Deerplay Moor, approximately 1.5 miles (2.4 km) north of Bacup. It forms the boundary between Manchester and Salford and empties into the River Mersey near Irlam.

Replacement of the steam engines began in 1922, starting at Whitworth Street. Four pumping engines were removed and replaced by electrically driven centrifugal pumps. The work was completed by 1924. The following year, the remaining pumps were retained, but their steam cylinders were removed, and the flywheels replaced by a helical gear drive, to connect the pumps to 220 hp (160 kW) electric motors. These were variable speed direct current devices, and a motor converter set had to be installed, to provide the low voltage DC supply from the incoming high voltage alternating current supply. The motor converter set was built in 1914, and was second-hand. The pumps at the Water Street station were converted to electrical operation in a similar manner soon afterwards. [11]

Decline

Demand for hydraulic power began to fall in the 1930s, as electric power became more popular, but although the number of customers dropped, the supply pipes were extended until the system reached its maximum length of 35.5 miles (57.1 km) in 1948. The Pott Street pumping station closed in 1939. By the 1960s, the motor converter set was 50 years old, and most of the pumps were older still. The effects of corrosion on high-pressure water mains were also a cause for concern. In 1964, a similar system in Glasgow, opened a year later than the Manchester system using water at 1,120 psi (77 bar) was switched off and some of its equipment was used to refit Whitworth Street station. The two centrifugal pumps and a converted steam pump were removed and replaced by two high-speed reciprocating pumps from Glasgow. Although not ideal for a diminishing network, because they were fixed speed devices, they provided a back-up system if there were problems at Water Street. [12]

By 1968, the length of pressure main was reduced to 26 miles (42 km), and the Waterworks Committee gave notice to all 120 customers that the system would be shut down in four years' time. By that time, the stations were supplying 2 million gallons (9.1 Megalitres) of pressurised water per year, down from the 360 million gallons (1,600 Ml) supplied when the system was at its peak. The system was switched off on 28 December 1972, when the Chairman of the Waterworks Committee stopped the pumps at a ceremony. [12]

The three hydraulic power stations were located at Whitworth Street West, Pott Street and Water Street.

The Whitworth Street station was opened in 1894 on the banks of the Rochdale Canal, between the canal and Oxford Road railway station, immediately to the west of St Mary's Hospital. It was the first to be upgraded to electrical operation, but was little used after 1964, as it held equipment bought from Glasgow, which was only used as a backup. After the system closed, its contents were sold for scrap and the building was demolished. [12]

Pott Street station was in Ancoats and opened in 1899. It was not electrified, and closed in 1939. Its site and the site at Pott Street have disappeared under the car park at the Central Retail Park in Ancoats.

The third station at Water Street, on the banks of the River Irwell was completed in 1909, and was designed in Baroque style by architect Henry Price. The station was electrified in 1925, and was the location for the closing ceremony at the end of 1972. After closure, it was used as a workshop by the City College. In 1992, it was designated a grade II listed structure, [13] and since 1994 has been part of the People's History Museum complex. One of the pump sets has been moved to the Museum of Science and Industry, where it has been restored to working order and forms part of a display about hydraulic power. [14] The pumps were made by the Manchester firm of Galloways. [10] It is now referred to as the Bridge Street station, because the part of Water Street on which it stood has disappeared in the redevelopment of the area.

Stationary engine

A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, generators, mills or factory machinery. The term usually refers to large immobile reciprocating engines, principally stationary steam engines and, to some extent, stationary internal combustion engines. Other large immobile power sources, such as steam turbines, gas turbines, and large electric motors, are categorized separately.

Hydraulic machinery machinery and tools that use liquid fluid power to do simple work

Hydraulic machines are machinery and tools that use liquid fluid power to do simple work, operated by the use of hydraulics, where a liquid is the powering medium. In heavy equipment and other types of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and becomes pressurised according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses and tubes.

Beam engine

A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt who added a separate condenser, Jonathan Hornblower and Arthur Woolf who compounded the cylinders, and William McNaught (Glasgow) who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals, but could be used to pump water to supplement the flow for a waterwheel powering a mill.

Hydraulic motor hydro pohon

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower but in today's terminology the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery.

Cornish engine

A Cornish engine is a type of steam engine developed in Cornwall, England, mainly for pumping water from a mine. It is a form of beam engine that uses steam at a higher pressure than the earlier engines designed by James Watt. The engines were also used for powering man engines to assist the underground miners' journeys to and from their working levels, for winching materials into and out of the mine, and for powering on-site ore stamping machinery.

It is named after the engineer Joseph Whitworth whose works once stood along the route. Whitworth Street West runs alongside the viaduct connecting Oxford Road and Deansgate railway stations: beyond Albion Street the Rochdale Canal is on the northern side. On the Albion Street corner is the building once occupied by the Haçienda nightclub at nos. 11-13 while further east on the same side is the Ritz.

Hydraulic hybrid vehicles, or HHVs use a pressurized fluid power source, along with a conventional internal combustion engine (ICE), to achieve better fuel economy and reductions in harmful emissions. They capture and reuse 70% - 80% of the vehicle's braking/decelerating energy compared to 55% for electric hybrids. For trucks and buses, this can also be less expensive than electric systems, due to the price of batteries required for the latter. Hydraulic hybrid vehicle systems can also weigh less than electric systems, due to the high weight of the batteries. This can lead to a lower impact on payload capacity, especially for heavy vehicle classes.

Water engine

The water engine is a positive-displacement engine, often closely resembling a steam engine with similar pistons and valves, that is driven by water pressure. The supply of water was derived from a natural head of water, the water mains, or a specialised high-pressure water supply such as that provided by the London Hydraulic Power Company. Water mains in the 19th century often operated at pressures of 30 to 40 psi, while hydraulic power companies supplied higher pressure water at anything up to 800 psi.

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.
