Pump definition and historical sources

A machine that delivers or pressurizes a liquid. The pump in its broadest sense is a machine that delivers fluid or pressurizes it, including some machinery that delivers gas. The pump transfers the energy of the prime mover's mechanical energy or other energy to the liquid, increasing the energy of the liquid.

The rise of water is very important for human life and production. There have been various water-lifting devices in ancient times, such as the Egyptian chain pump (previous 17th century), China's Jade eaves (former 17th century), Sacrifice (former 11th century), waterwheel (1st century AD), and 3rd century BC Ancient Greek Archimedes invented the spiral rod and so on. Around 200 BC, the ancient Greek craftsman Cte Sibius invented the most primitive piston pump-fire pump. As early as 1588, there was a record of a 4-blade vane pump, and various other rotary pumps have appeared one after another. In 1689, France's D. Papin invented a four-blade impeller volute centrifugal pump. In 1818, a centrifugal pump with a radial straight blade, a semi-open double suction impeller and a volute was introduced in the United States. From 1840 to 1850, the HR Worthington of the United States invented a piston pump that directly acted on the steam opposed to the pump cylinder and the steam cylinder, marking the formation of a modern piston pump. From 1851 to 1875, multistage centrifugal pumps with guide vanes were invented one after another, making it possible to develop high-lift centrifugal pumps. Subsequently, various pumps were introduced one after another. With the application of various advanced technologies, the efficiency of pumps has been gradually improved, and the performance range and applications have also been gradually expanded.
