Structures Of Non-Positive Displacement Pumps
(AREA)
Abstract
Multistage centrifugal pump or fan characterized in that at least the stationary parts of the guide device separate phases of a multi-phase centrifugal pump or fan surrounding the rotor wheels and driving the medium under pressure to the successive rotor wheels they are constructed as separate parts in planes normal to the pump shaft and the reversing steps that drive the pressurized medium to the successive rotor wheels are constructed as separate parts in normal planes away from the pump and the reversal steps leading to pressurized medium from one phase to the next are constructed as open passages at least partially in an axial direction and are covered in the pump mounted by the separated annular plates.
