摘要: A centrifugal fan includes a housing and an impeller. The housing includes a first surface and a flow channel wall. The first surface has a surrounding section and an air inlet section. The surrounding section encircles the air inlet section. The flow channel wall defines a flow chamber and an air outlet, and at least a sidewall of the flow channel wall has a tongue portion close to the air outlet. The impeller is rotatably connected within the flow chamber. The surrounding section plus the air inlet section is an area on the first surface, on which the impeller is projected, and the surrounding section has a convex structure.

摘要: Embodiments of the invention are directed to a rotor for a molten metal pump and a molten metal pump including the rotor. The rotor has a main body and a top comprised of a material that is at least twice as hard as the main body. The top, among other things, may form a first portion of each rotor blade wherein the first portion directs molten metal into a pump chamber or other structure in which the rotor is mounted.

摘要: An inner peripheral side of the blade with respect to an apex (P) of the leading edge protruding portion extends forward in the fan rotating direction with respect to the apex (P). A radius (Rq) at a position of an apex (Q) of the trailing edge protruding portion is larger than a radius (Rp) at a position of the apex (P). The radius (Rq) at the position of the apex (Q) is larger than an intermediate radius (Rm) between a radius (Ro) of an outer peripheral edge and a radius (Ri) of an inner peripheral edge.

摘要: A centrifugal pump for pumping fluid includes a volute having an upstream inlet that receives the fluid and a downstream outlet that discharges the fluid. An impeller is disposed in the volute and comprises a plurality of impeller vanes. The impeller is configured to rotate about an axis of rotation so that the plurality of impeller vanes accelerates the fluid radially outwardly from the upstream inlet to the downstream outlet. The impeller is further configured to discourage air-lock of the centrifugal pump by expelling air away from the upstream inlet as the impeller rotates about the axis of rotation.
