Fan machine Wikipedia. This article is about mechanical fans. For hand powered fans, see Hand fan. For other uses, see Fan. Household electric box fan with a propeller style blade. A household electric floor fan. A fan is a machine used to create flow within a fluid, typically a gas such as air. The fan consists of a rotating arrangement of vanes or blades which act on the fluid. The rotating assembly of blades and hub is known as an impeller, a rotor, or a runner. Usually, it is contained within some form of housing or case. This may direct the airflow or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Fans produce flows with high volume and low pressure although higher than ambient pressure, as opposed to compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to a fluid stream, and devices that take advantage of this, such as anemometers and wind turbines, often have designs similar to that of a fan. Typical applications include climate control and personal thermal comfort e. While fans are often used to cool people, they do not actually cool air if anything, electric fans warm it slightly due to the warming of their motors, but work by evaporative cooling of sweat and increased heat convection into the surrounding air due to the airflow from the fans. Thus, fans may become ineffective at cooling the body if the surrounding air is near body temperature and contains high humidity. Rapidshare Incubus If Not Now When on this page. During periods of very high heat and humidity, governments actually advise against the use of fans.

HistoryeditThe punkah fan was used in India about 5. BCE. It was a handheld fan made from bamboo strips or other plant fibre, that could be rotated or fanned to move air. During British rule, the word came to be used by Anglo Indians to mean a large swinging flat fan, fixed to the ceiling, and pulled by a servant, called the punkawallah. For purposes of air conditioning, the Han Dynasty craftsman and engineer Ding Huan fl. CE invented a manually operated rotary fan with seven wheels that measured 3 m 1. Tang Dynasty 6. 189. Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the rotary fan became even more common during the Song Dynasty 9. In the 1. 7th century, the experiments of scientists like Otto von Guericke, Robert Hooke and Robert Boyle, established the basic principles of vacuum and airflow. The English architect Sir Christopher Wren applied an early ventilation system in the Houses of Parliament that used bellows to circulate air. Wrens design would be the catalyst for much later improvement and innovation. The first rotary fan used in Europe was for mine ventilation during the 1. Georg Agricola 1. John Theophilus Desaguliers, a British engineer, demonstrated a successful use of a fan system to draw out stagnant air from coal mines in 1. Parliament. 6 Good ventilation was particularly important in coal mines to reduce casualties from asphyxiation. The civil engineer John Smeaton, and later John Buddle installed reciprocating air pumps in the mines in the North of England. However, this arrangement was not ideal as the machinery was liable to breaking down. With the advent of practical steam power, fans could finally be used for ventilation. ABB Motors Basic Motor Technology for ABB Motors totally enclosed, fan cooled, threephase squirrel cage motors. This catalogue includes basic technical information. A starter also self starter, self, cranking motor, or starter motor is a device used to rotate crank an internalcombustion engine so as to initiate the engines. In 1. 83. 7 William Fourness of England installed a steam driven fan at Leeds. In 1. William Brunton, was made operational in the Gelly Gaer Colliery of South Wales. The model was exhibited at the Great Exhibition of 1. Also in 1. 85. 1 David Boswell Reid, a Scottish physician, installed four steam powered fans in the ceiling of St Georges Hospital in Liverpool, so that the pressure produced by the fans would force the incoming air upward and through vents in the ceiling. Improvements in the technology were made by James Nasmyth, Frenchman Theophile Guibal and J. R. Waddle. 1. 0ElectricaleditBetween the years 1.

VO/FJ/MY-3555971/bondioli-and-pavesi-axial-piston-pumps-500x500.jpg' alt='Axial Starter Motor Pdf Download' title='Axial Starter Motor Pdf Download' />New Orleans, LA resident Schuyler Skaats Wheeler invented a fan powered by electricity. It was commercially marketed by the American firm Crocker Curtis electric motor company. In 1. 88. 2, Philip Diehl developed the worlds first electric ceiling fan. During this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 2. In 1. 90. 9, KDK of Japan pioneered the invention of mass produced electric fans for home use. In the 1. 92. 0s, industrial advances allowed steel fans to be mass produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1. 93. 0s, the first art deco fan the swan fan was designed. By the 1. 94. 0s, Crompton Greaves of India became the worlds largest manufacturer of electric ceiling fans mainly for sale in India, Asia and the Middle East. By the 1. 95. 0s, table and stand fans were manufactured in colors that were bright and eye catching. Window and central air conditioning in the 1. But in the mid 1. In 1. 99. 8, Walter K. Boyd invented the HVLS ceiling fan. It was a slow moving fan with an eight foot diameter. Axial Starter Motor Pdf' title='Axial Starter Motor Pdf' />Due to its size, the fan moved a large column of air and continuously mixed fresh air with the stale air inside. They are used in many industrial and agricultural settings, because of their energy efficiency. Revolving blade fans are made in a wide range of designs. They are used on the floor, table, desk, or hung from the ceiling. They can also be built into a window, wall, roof, chimney, etc. Most electronic systems such as computers include fans to cool circuits inside, and in appliances such as hair dryers and portable space heaters and mountedinstalled wall heaters. They are also used for moving air in air conditioning systems, and in automotive engines, where they are driven by belts or by direct motor. Fans used for comfort create a wind chill by increasing the heat transfer coefficient, but do not lower temperatures directly. Fans used to cool electrical equipment or in engines or other machines do cool the equipment directly by forcing hot air into the cooler environment outside the machine. There are three main types of fans used for moving air, axial, centrifugal also called radial and cross flow also called tangential.

PTC1. 4 provides standard procedures for conducting and reporting tests on fans, including those of the centrifugal, axial, and mixed flows. Axial flowedit. An axial box fan for cooling electrical equipment. Axial flow fans have blades that force air to move parallel to the shaft about which the blades rotate. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in wind tunnels. Ncss 9 Serial Number. Axial flow fans are applied in air conditioning and industrial process applications. Standard axial flow fans have diameters from 3. Pa. Special types of fans are used as low pressure compressor stages in aircraft engines. Examples of axial fans are Table fan Basic elements of a typical table fan include the fan blade, base, armature and lead wires, motor, blade guard, motor housing, oscillator gearbox, and oscillator shaft.
