Patent attributes
There is provided a centrifugal turbo machine comprising: a volute casing; a rotation axis coupled with the volute casing through a bearing; an impeller which is coupled to an end of the rotation axis and sucks fluid with a centrifugal force due to its rotation; and an axial thrust control member which is coupled to the volute casing at the rear of the impeller in a direction in which the fluid flows and prevents rotation of the fluid by the impeller. It is easy to fabricate and install the centrifugal turbo machine and it is possible to reduce the difference in static pressure of fluid by using the economical axial thrust control member so as to prevent the generation of the axial thrust, which results in damage of the bearing, etc. Therefore, it is possible to stably operate the centrifugal turbo machine.
