Semi-portable Engine
A semi-portable engine is a form of stationary steam engine. They were built in a factory as a single unit including the boiler, so that they could be rapidly installed on site and brought into service. Although the earliest examples can be dated to Richard Trevithick in around 1800, the type is best known as the products of Robey & Co. of Lincoln who patented their design in 1873. The distinctive Robey design was an undertype with one or two cylinders mounted beneath a locomotive boiler. The cylinders were mounted beneath the smokebox and a transverse crankshaft ran crossways beneath the boiler, just ahead of the firebox. The frame of these engines was a large iron box casting that formed a single piece foundation for both the engine and boiler. Owing to the small height available with this pre-fabricated foundation, the semi-portable engine had no large flywheel, as was standard practice for stationary engines. The need for a more even power delivery, without the smoothing effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skansen W Chabówce -maszyna 09
Skansen (; "the Sconce") is the oldest open-air museum and zoo in Sweden located on the island Djurgården in Stockholm, Sweden. It was opened on 11 October 1891 by Artur Hazelius (1833–1901) to show the way of life in the different parts of Sweden before the industrial era. The name has also been used as a noun to refer to other open-air museums and collections of historic structures, particularly in Central and Eastern Europe, but also in the United States, e.g. Old World Wisconsin and Fairplay, Colorado. History The 19th century was a period of great change throughout Europe, and Sweden was no exception. Its rural way of life was rapidly giving way to an industrialised society and many feared that the country's many traditional customs and occupations might be lost to history. Artur Hazelius, who had previously founded the Nordic Museum on the island of Djurgården near the centre of Stockholm, was inspired by the open-air museum, founded by King Oscar II in Kristiani ...

Vertical Cross-tube Boiler
A cross-tube boiler was the most common form of small vertical boiler. They were widely used, in the age of steam, as a small donkey boiler, for the independent power of winches, steam cranes etc. The boiler has the advantage of simple robust construction, in particular requiring little regular maintenance. It is relatively inefficient, which was not a serious drawback to the purposes for which it was used. However it was also of limited heating surface, thus limiting its sustained output power, compared to other boiler designs. For that reason it was rarely used when power was required continuously, such as for locomotives. However as the boiler is of relatively large internal volume relative to its power, this acts as a transient reserve of steam. Applications such as cranes only require steam intermittently, allowing the boiler to recover pressure between lifts. Construction The boiler consists of a cylindrical vertical external shell, with a large firebox inside this, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House-built Engine
A house-built engine is a stationary steam engine that is built into an engine house, such that it uses the masonry of the engine house as an integral part of the support of the engine. Beam engines Most house-built engines were early beam engines. A 'bob wall' in the engine house supported the pivot axle of the beam or 'bob'. This wall could be an internal wall, with both ends of the beam inside the house, but it was commonly the end wall of the house and so the beam projected to the outside. For a heavy beam, the bob wall was required to be extremely substantial. Early engines were used for pumping mines or wells, so as well as the weight of the beam, the house had to also support the weight of the long pump rod, reaching down to the depths of the mine. Beam engines appeared during the 18th century. The only technologies at this time that could support the weight of an engine's beam were masonry and timber-framing, as the work of either shipwrights or millwrights. Cast iro ...

Winding Engine
A winding engine is a stationary engine used to control a cable, for example to power a mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as ''winding engines''. Early winding engines were hand, or more usually horse powered. The first powered winding engines were stationary steam engines. The demand for winding engines was one factor that drove James Watt to develop his rotative beam engine, with its ability continuously to turn a winding drum, rather than the early reciprocating beam engines that were only useful for working pumps. They differ from most other stationary steam engines in that, like a steam locomotive, they need to be able to stop frequently and also reverse. This requires more complex valve gear and other controls than are needed on engines used in mills or to drive pump A pump is a device that moves fluids (liquids or gases), or ...

Air Compressor
An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use. The kinetic energy provided by the compressed air can be used for a variety of applications such as pneumatic tool as it is released air and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid. Classification Compressors may be classified according to the pressure delivered: # Low-pressure air compressors (LPACs), which have ...

Water Pump
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. Whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Launch-type Boiler
A launch-type, gunboat or horizontal multitubular boiler is a form of small steam boiler. It consists of a cylindrical horizontal shell with a cylindrical furnace and fire-tubes within this. Their name derives from the boiler's popular use at one time for small steam yachts and launches. They have also been used in some early Naval torpedo boat destroyers. Description The cylindrical furnace or firebox fits entirely within the boiler's outer shell. Unlike the locomotive boiler, there is no firebox grate emerging beneath the main boiler. The boiler has similarities with both the locomotive boiler (the multiple small fire-tubes), and the Scotch marine boiler (the short cylindrical furnace). As a fire-tube boiler it has generous heating area and so is an effective steamer. Firebox construction is also simpler, thus cheaper, than for the locomotive firebox. As the circular furnace is largely self-supporting against boiler pressure, it did not require the extensive and costly st ...

Steam Crane
A steam crane is a crane powered by a steam engine. It may be fixed or mobile and, if mobile, it may run on rail tracks, caterpillar tracks, road wheels, or be mounted on a barge. It usually has a vertical boiler placed at the back so that the weight of the boiler counterbalances the weight of the jib and load. They were very common as railway breakdown cranes and several have been preserved on heritage railways in the United Kingdom.

Lancashire Boiler
A shell or flued boiler is an early and relatively simple form of boiler used to make steam, usually for the purpose of driving a steam engine. The design marked a transitional stage in boiler development, between the early haystack boilers and the later multi-tube fire-tube boilers. A flued boiler is characterized by a large cylindrical boiler shell forming a tank of water, traversed by one or more large flues containing the furnace. These boilers appeared around the start of the 19th century and some forms remain in service today. Although mostly used for static steam plants, some were used in early steam vehicles, railway locomotives and ships. Flued boilers were developed in an attempt to raise steam pressures and improve engine efficiency. Early haystack designs of Watt's day were mechanically weak and often presented an unsupported flat surface to the fire. Boiler explosions, usually beginning with failure of this firebox plate, were common. It was known that an arched stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stationary Steam Engine
Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Types of stationary steam engine There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: * Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft. *Table engines have the crosshead above the vert ...
