Compressor - a device for compressing and supplying air or other gas under pressure. The degree of pressure increase in K. is more than 3. To supply air with an increase in its pressure less than 2 - 3 times, blowers are used, and at pressures up to 10 kn / m2 (1000 mm of water cm. ) - fans. K. first began to be used in the middle of the 19th century. , in Russia they have been built since the beginning of the 20th century. The foundations of the theory of centrifugal machines were laid by L. Euler, the theory of axial compressors and fans was created thanks to the works of N. Ye. Zhukovsky, S. A. Chaplygin and other scientists. By the principle of operation and the main design features, piston, rotary, centrifugal, axial and jet compressors are distinguished. Compressors are also subdivided according to the type of gas to be compressed (air, oxygen, etc. ), according to the created pressure ph (low pressure - from 0.3 to 1 MN / m2, medium - up to 10 MN / m2 and high - above 10 MN / m2), in terms of productivity, that is, the volume of sucked Vws (or compressed) gas per unit of time (usually in m3 / min) and other features. The compressors are also characterized by a speed n and a power input N.
