1- Compressor Dinâmico

Os compressores dinâmicos radias, no qual o escoamento de gás de saída é perpendicular ao eixo, são chamados compressores centrífugos. Há modelos de …exibir mais conteúdo…

The difference between constructive and application of the two, and quite noticeable. Centrifugal compressors are suitable for poison gas, flammable, which need to compress a large amount of gas at high pressure. The axial compressors are suitable for less hazardous gases, large flow and discharge pressure which is not so high (up to 30 bar), although it is possible to obtain compression rates two times higher than that of the centrifugal compressor in a same housing.

1.1-Radial flow
The radial compressors are flow machines as the axial compressors, into which the kinetic energy is converted into pressure. Air is sped up from the rotation center, in direction to the periphery, that is, is admitted by the first helix (rotor endowed with made use blades radially), axially, is sped up and banishes radially.

1.2-Radial flow
Air is impelled for the walls of the chamber and later in direction to the axle and from there in the radial direction for another chamber successively in direction to the exit.

1.3-Ejetor

Os ejetores a vapor proporcionam uma forma confiável e econômica de se obter vácuo. As vantagens iniciais dos ejetores a vapor são seu baixo custo inicial, inexistência de partes móveis e simplicidade de operação. O ejetor a vapor convencional é composto de quatro partes básicas: cabeçote de vapor, bico ou bicos, câmara de mistura e difusor. A imagem abaixo ilustra o funcionamento básico de um ejetor:
