摘要: The invention relates to a rotary pump, comprising a rotor (1, 1', 1") having delivery elements (3, 3', 3", 4, 4', 4") which deliver at least a portion of a fluid in the axial direction of the rotor. Two delivery elements or groups of delivery elements are provided on the rotor for delivering the fluid and deliver the fluid to be delivered in mutually opposing axial directions of the rotor, so that the axial thrust components substantially compensate each other. The fluid flows flowing counter to each other jointly give way in the radial direction of the rotor and can be jointly discharged through the volute casing (9) and utilized.

摘要: An impeller assembly and method of providing a plurality of radially-aligned aerodynamic channels including a rim plate defining a plurality of blades and the backplate defining a blade interlock structure for aligning and coupling the plates together. The rim plate defines a plurality of fluid-engaging blades with the aerodynamic channels being defined between adjacent pairs of the blades. The interlock structure includes a plurality of tine-shaped interlocks extending from the backplate. Each blade of the impeller may engage the interlock structure in a saddle manner. The backplate is defined by areas of reduced thickness allowing outer portions of the backplate to flex (rotate) toward further contact with the rim plate. The impeller assembly is provided with a plurality of aerodynamic channels defined by complex curved surfaces of the back plate and the rim plate to improve efficiency.

摘要: The present invention discloses an axial flow impeller comprising a hub and at least three base blades mounted around the hub evenly, in which the base blades are capable of doing work on an external object, and a cover blade is detachably mounted in the front and/or rear of each base blade. When the axial flow impeller of the present invention is applied in a medium environment having a high density and viscosity, it will meet the requirement only by virtue of the base blade with the cover blade being removed; when the axial flow impeller of the present invention is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the axial flow impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the axial flow impeller of the present invention can be adaptable to different medium environments and efficiency requirements, and thus the axial flow impeller can have good adaptibility, need minimal investment cost and can be convenient to use.
