|Centrifugal pump in particular for waste water or polluted water|
The invention relates to a centrifugal pump, in particular a waste water submersible pump having an impeller (1), of which the end face facing the pump intake opening is open and only the end face of the impeller facing away from the intake opening (8) is covered by a circular coaxial impeller hub (2), on which the curved vanes (3, 4) are fastened, and in particular moulded on, wherein the base plate (7) having the intake opening (8) facing the impeller (1) or at least one segment (7a) of the base plate is mounted so as to be movable against spring pressure (20) in such a way that the distance thereof from the impeller (1) and thus from the impeller vanes (3, 4) changes.. .
|Method to reduce entrance losses to increase fan inlet flow and reduce acoustic noise|
A cooling system for optimizing fan air flow performance without compromising acoustic performance is disclosed. At least three fan feature embodiments are disclosed: (1) sloped fan blades, (2) sloped impeller hubs, and (3) inlet flow guidance features.
|Turbine rotor for an exhaust-gas turbine and producing the turbine rotor|
A turbine rotor as a turbine impeller made of a high-temperature-resistant metal alloy and a rotor shaft made of steel. The impeller hub and the rotor shaft end are connected together in a metallurgically bonded manner by way of a brazed connection.
Continental Automotive Gmbh
|Torque converter impeller including impeller shell having thinned section|
An impeller for a torque converter is provided. The impeller includes an impeller shell including an inner circumference, an outer circumference and a radial extension extending radially outward from the inner circumference.
Schaeffler Technologies Gmbh & Co. Kg
A centrifugal compressor for which θ−α>0° and 0°<θ<34°, when the angle formed by a diffuser inlet hub-side line (5a) and the radial direction at a point b in the meridian plane is θ, and the angle formed by a tangent line (3b) and the radial direction at a point a of an impeller hub-side line (3a) nearest the inlet of the diffuser (5) is α. Thus, skewing of the velocity distribution of a gas within the diffuser of the centrifugal compressor is eliminated..
Mitsubishi Heavy Industries Compressor Corporation
A torque converter includes a front cover, an impeller, a turbine and a stator. The impeller includes an impeller shell coupled to the front cover, a plurality of impeller blades disposed inside the impeller shell, and an impeller hub.
|Autogenously welded impeller of a torque converter|
A torque converter impeller is provided. The torque converter impeller includes an impeller shell and an impeller hub.
|Multiphase pumping system|
A centrifugal pump has a gas accumulation reduction system to reduce the risk of gas locking caused by the accumulation of gas at the inlet of the impeller. The gas accumulation reduction system includes: (i) one or more diffuser ports extending through the hub of a diffuser; and (ii) one or more recirculation passages extending through the hub of an impeller.
|Impeller with associated wear member|
An impeller for a torque converter includes a rotating housing portion, a blade portion configured to create fluid flow for pumping fluid to a turbine of the torque converter, and an impeller hub portion configured to couple the impeller to the torque converter and rotate about an output shaft of the torque converter. The impeller hub portion defines an inner surface having an annular recess, and at least one inlet passage and at least one outlet passage to provide flow paths for fluid entering and exiting the impeller.
