FLUID MACHINE AND FLUID MACHINE SYSTEM EQUIPPED WITH SAME

摘要

An object is to provide a fluid machine whereby it is possible to improve performance, for example, expand a flow-rate operation rage with a simplified shape of an intake pipe. A fluid machine includes an impeller 6 mounted to a rotation shaft 5, a housing 2 which houses the impeller rotatably, and an intake pipe 20 for supplying a fluid to the housing. The intake pipe 20 includes at least a first bend portion disposed on a first plane P 1 , and a second bend portion disposed at a downstream side of the first bend portion and on a second plane which is different from the first plane. The second bend portion includes an upstream section having a center axis oriented along a center axis of a downstream section of the first bend portion and a downstream section having a center axis oriented along an axial direction of the impeller at a front of the impeller. The intake pipe has a constant cross-sectional shape from an upstream end of the first bend portion to a downstream end of the second bend portion.
