History of the pumps

The invention pump dates back to antiquity. The first NA to suppress fires, which invented the ancient mechanic Ktesiby, was described in 1. BC. Oe. The ancient Greek scientists Heron from Alexandria in the book "Pneumatica", and then M. Vituviem at work "De Architectura". Simple wooden pumps with a through piston for lifting water from wells, probably used even earlier. Before 18. Piston pumps, compared with water engine used sparingly. In the future, due to increased water demand and the need to increase the height of its filing, especially after the steam engine, pumps gradually pushed the pumping machine. Requirements for pumps and conditions of their use became more diverse, so along with piston pumps began to create rotational, as well as various devices for feeding pressurized fluids. T., historically there have been three areas of further development: the creation of reciprocating, rotary and hydraulic devices with no moving working parts.

The rise in the development of reciprocating pumps. observed in the late 18 century. when their manufacture began to apply the metal and use the drive from the steam engine. Since the mid 19. Have been widely implemented in the production of steam direct acting piston pumps for this period include the establishment wing of pumps, a prototype of which is a piston pump with a circular cylinder is described by the French engineer A. Rammell in 1588 ("Le diverse et articiose machine"). Development of the theory of piston N. closely associated with the work of local scientists and engineers (C. Bach, G. Berg, AP Hermann, Shukhov, PK Khudyakov, I. Kukolevsky, AA Burdakov, etc.). Advances in reciprocating pumps have been widely used also in creating reciprocating compressors, hydraulic presses and other devices, but the piston pumps ranging from 20 to 30-ies. 20. Became markedly displaced from a number of areas centrifugal, rotary, etc.
