摘要： A method of fabricating a pump casing that includes an inlet, an outlet and a pump casing body. The pump casing body has a neck portion that defines a groove. The inlet is formed by stamping a sheet of metal to form a basin-shaped body, wherein the stamping the center portion of the basin-shaped body forms the inlet. Centering the basin-shaped body about a first axis and using one set of roller dies to roll form the basin-shaped body into a pump casing body. The pump casing body includes, starting from the inlet, an inlet end plate, a passage side plate, a motor end plate and a neck portion. Stamping the passage side plate forms the outlet. A set of roller dies include an internal roller die and a mating external roller die, wherein both are rotatably mounted along a second and third axes, respectively, wherein the first, second and third axes are parallel to but spaced from each other.

摘要： The invention provides a diffuser assembly constructed of internal and external concentrically nested bowl-shaped shells for directing an outward flow of compressed air from a centrifugal compressor impeller to an axially rearward diffused annular flow. One of the shells is formed with grooves separated by seam edges and the other shell includes a smooth surface of revolution. The grooves on the one shell are closed by the other shell when the two shells are nested together and the seam edges are secured to the smooth surface by fastening means thus defining individual diffuser ducts extending from the compressor impeller to the outer shell edges. The shells can be easily manufactured from metal castings and sheet metal respectively, thereby eliminating much of the cost and the time involved in fabricating prior art diffusers of multiple formed pipes brazed to a separately machined hub. This construction can be easily reinforced for vibration control and the thickness of diffuser duct walls can be optimized for improved performance and minimum weight. The designers are freed from many of the constraints imposed by conventional diffuser design. The shape and cross-section of the diffuser ducts become completely independent of the manufacturing method, permitting the diffuser duct shape to be optimized for aerodynamic efficiency. The costs of production are reduced since tooling costs and manufacturing complexity are dramatically reduced when only two shell parts are required.
摘要翻译：本发明提供了一种由内部和外部同心嵌套的碗形壳体构成的扩散器组件，用于将离心式压缩机叶轮向外的压缩空气流引导到轴向向后扩散的环形流。其中一个壳体形成有由接缝边缘分开的沟槽，另一个壳体包括平滑的旋转表面。当两个壳嵌套在一起时，一个壳体上的凹槽由另一个壳体封闭，并且接缝边缘通过紧固装置固定到光滑表面，从而限定从压缩机叶轮延伸到外壳边缘的各个扩散器管道。壳可以容易地由金属铸件和金属板制成，从而消除了制造现有技术的多个形成的钎焊到单独加工的毂的成形管的扩散器所花费的大量成本和时间。这种结构可以轻松加强振动控制，扩散管壁的厚度可以优化，以提高性能和最小重量。设计师摆脱了常规扩散器设计所施加的许多限制。扩散器管道的形状和横截面完全独立于制造方法，允许对空气动力学效率优化扩散器管道形状。生产成本降低，因为只需要两个壳体部件时，模具成本和制造复杂性就会大大降低。

摘要： A compressor rotor includes coaxially adjoining disks having corresponding rows of rotor blades. A forward shaft is affixed to a forward disk and includes an annular seat for being mounted in a bearing to support the rotor at its forward end. A blisk coaxially surrounds the shaft axially between the seat and forward disk, and is removably fixedly joined piggyback to the shaft. In a repair method, the blisk may be removed from the compressor rotor without requiring teardown of the compressor rotor itself.

摘要： The invention is a turbomachinery module (10) whose forwardmost vanes, which are the most damage susceptible vanes in the module, are easily removable and replaceable without substantial disassembly of the module. The module includes a case (12) and a forwardmost array (1V) of vanes. Each vane (34) of the forwardmost array has an axially proximal and distal end (90, 92) relative to the forward end (16) of the case. The distal end of each vane has a foot (102) that abuts but is not connected to a vane guide (32) on the case. The proximal end of each vane has an attachment bracket (110) that can be secured to or disengaged from a vane support (28) on the case. Vane removal is accomplished by disengaging the attachment bracket (110) from the vane support (28) and withdrawing the vane through the forward end of the case. The invention improves upon conventional turbine modules in which the forwardmost vane array is removable only from the aft end of the case after the module has been substantially disassembled. As a result the damage susceptible vanes can be accessed and serviced in less time and at a lower cost than would otherwise be possible.

The device comprises a volute channel structure and a throat partition. The volute channel structure is a spiral volute channel and surrounds an impeller exit side. A leading edge of the volute channel is a water-cut angle. A sectional area of the volute channel is wider and deeper from the water-cut angle. An outer diameter of the volute channel is a concentric arrangement. The throat partition connects to a rear edge of the volute channel and extends toward an exit of the casing so as to that the throat partition is at least and mainly an extension of the volute channel; the extension of the volute channel overlaps the leading edge of the volute channel to have the total length of the volute channel, the total length is able to surround the impeller exit side over 360 degrees.
