    摘要： An impeller (16) includes a hub (32) and a plurality of blades (30). Each blade (30) extends out from the hub (32). The impeller (16) has an original diameter defined by respective tips (38) of the plurality of blades (30). Each blade (30) includes a central axis (140), a leading edge (150), a trailing edge (152), an original profile (132), and a plurality of trim profiles (134, 136). The original profile (132) has an outside portion and a trailing portion (138). The outside portion has an angle within a range of about 40° to about 90° from the central axis (140) and the trailing portion having an angle within a range of about 10° to about 50° from the central axis (140). A first selected trim profile (134) of the plurality of trim profiles (134) extends along a first line parallel to the outside portion and a second line parallel to the trailing portion.

    摘要： Molten metal transfer pump comprises a case (1), in which a shaft (4) with the impeller (5) mounted on the shaft (4) is installed on the upper bearing (2) and the lower journal plain bearing (3). The lower journal plain bearing (3) is comprised of the rotor (15) and stator (16) parts. The rotor part (15) is made in the form of two split bushings (17) mounted on the shaft (4), and the stator part (16) is made in the form of two split bushings (18) fixed in the cage (19) in axial alignment with the shaft (4). Bushings (17) and (18) are fixed correspondingly with flat rings (24) and (33) and composed of cylinder segments (20), (28) equidistantly placed in a circumferential direction, located correspondingly in the cylindrical groove (21) on the shaft and cylindrical groove (29) of the cage (19) and fixed with cone hold-down rings (22), (30) radially, and with spring rings (23), (31) axially. The pump has an easy-to-manufacture design of the lower journal bearing and excludes the possibility of bearing tearing, thus providing for improved reliability of the pump at its operation.

    摘要： The invention provides a spiral flow constant pressure pump, comprising a pump body, a pump casing and an impeller; the pressure drop between the end face of pump rear cover and the rear end face of impeller auxiliary blade is used for providing wash water to sealing device; a hole is opened in the high pressure area of the end face of pump rear cover; the position of the hole for entering the seal cavity is close to the sealing device, leading expectant high pressure water into the seal cavity; a hole is opened in the low pressure area of the end face of pump rear cover; the position of the hole for exiting the seal cavity is far away from the sealing device; the expectant high pressure water that enters the seal cavity will flow back to low pressure area through the drainage hole along flow direction after washing the sealing device; the pump recycles a part of energy, improves the hydraulic efficiency, decreases the turbulent loss and takes way the gas might exist in the seal cavity; the extended orifice sleeve reduces the damage to the pressure drop of the auxiliary blade caused by the high pressure water leaked from seal cavity and thus ensures the balance effect of the auxiliary blade.

    摘要： A rotor shaft for a high speed motor that has a coating that is secured to a shaft body. The coating and the shaft body are formed from dissimilar materials. More specifically, the coating may be an alloy material, such as, for example, a copper alloy, while the shaft body may be a steel material. According to certain embodiments, the alloy material of the coating may be secured to at least a portion of a rotor body blank in a solution treated condition via a low temperature welding procedure. Additionally, the coating may be hardened, such as for example through the use of an age hardening process. The coating and the rotor body blank may be machined together to form the rotor shaft. According to certain embodiments, such machining may configure the rotor shaft for use with a turbo-compressor that is configured for air compression.
