Introduction to the history of pump

The pump is conveying liquid or causes the liquid turbo-charged machinery. It transmits the mechanical energy or other external energy transmitted to the liquid, causes the liquid energy increase. Pumps are mainly used for conveying liquid, including water, oil, the sour lye, the emulsion, hangs the emulsion and the liquid metal and so on, also may transport the liquid, the mixture of gases as well as contains the suspended solid liquid.

The ascension of water is very important for human life and production. Ancient times has had a variety of water appliances, such as Egypt's chain pump (17th century BC), China's JieGao (17th century BC), jigger (11th century BC) and the water wheel (the 1st century AD). Is also famous in the 3rd century BC, invented by Archimedes screw, smooth can continuously to the water several meters high, its principle is still used by modern screw pump.

Around 200 BC, the ancient Greek craftsmen invented by Kurt west than uz fire pump is one of the most primitive piston pump, has typical piston pump's main components, but the piston pump only after the steam engine got rapid development.

1840 ~ 1840, the United States worthington pump cylinder and a steam cylinder opposed, steam directly impact piston pump, marks the formation of modern piston pump. In the 19th century was the highlight of the piston pump development period, which was used in hydraulic press and other machinery. However, as a surge in demand, since the 1920 s, low speed and flow rate is limited by a lot of piston pump is gradually replaced by high-speed centrifugal pump and the rotary pump. But in the field of high pressure small flow reciprocating pump still occupy the main position, especially the diaphragm pump, plunger pump with unique advantages, application is increasing.

Water use of centrifugal force of the ideas first appeared in the leonardo Da Vinci in the sketch. In 1689, the French physicist Mr Invented the four blade volute centrifugal pump impeller. But closer to the modern power plant pump, is in the United States in 1818 with a radial straight blade, half open double suction impeller and volute pump Massachusetts. From 1851 to 1875, multistage power station with guide vane pump was invented, making it possible to development of high head power station pump.
