Conversely, a double flow radially split pump/PAT design involves a single radial open rotor fed by two symmetric inlets and enable processing a higher flow rate with respect to a standard radial unit. [9] A second type of pump/PAT design is the axial one, in which the fluid interacts with a propeller following a trajectory parallel to the pump ...
An axial-flow pump for industrial use. An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
In these types of pumps the volute casing is split axially and the split line at which the pump casing separates is at the shaft's centerline. They are typically mounted horizontally due to ease in installation and maintenance. Radial split: The pump case is split radially, the volute casing split is perpendicular to shaft centre line.
no axial internal forces at the drive shaft bearing high reliability A disadvantage is the bigger radial dimensions in comparison to the axial piston pump , but it could be compensated with the shorter construction in axial direction.
Whereas for an axial turbine the rotor is 'impacted' by the fluid flow, for a radial turbine, the flow is smoothly oriented perpendicular to the rotation axis, and it drives the turbine in the same way water drives a watermill. The result is less mechanical stress (and less thermal stress, in case of hot working fluids) which enables a radial ...
In an OFRT these are typically mounted concentrically, in the same plane as the turbine. However the guide vanes can also be designed in an axial or diagonal/mixed configuration. Runner/Turbine: The passage between the blades has a converging-diverging profile. The majority of the head loss or pressure drop occurs as the working fluid passes ...
A centrifugal pump is an example of a radial flow turbomachine. Mixed flow turbomachines – When axial and radial flow are both present and neither is negligible, the device is termed a mixed flow turbomachine. [9] It combines flow and force components of both radial and axial types. A Francis turbine is an example of a mixed-flow turbine.
