摘要： An improved pump shell for a multistage metal working pump includes a plurality of pump shell units housed in series within a hollow cylindrical casing and has the impellers driven by a shaft. Each pump shell unit has a inner shell which forms a holding end at one side and a sealing flange at another side. The holding end of one pump shell may align and engage precisely and easily with the sealing flange of an adjacent pump shell unit to form a smooth fluid passage from the inlet of the impeller through the inner shell so that pumping efficiency may be enhanced with less turbulence. The sealing flange, holding end and the casing also form a close annular compartment for holding a seal ring inside to provide effective sealing function. The pump shell may be produced by stamping at low cost.

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： An pump casing for a sheet metal pump includes a pump body made by pressing or roll forming a sheet metal, a reinforced member which includes a water guide unit and a flange unit separately made by casting or CNC machining and a seal ring engaged with the water guide unit. The pump body is a simple basin shape which can be produced with less stress concentration. The water guide unit may be made with a more precise volute for achieving better pumping efficiency. The reinforced member may increase structural strength of the pump casing for withstanding greater pumping pressure and external forces. The seal ring may be positioned precisely without dislocation because it engages with the water guide unit rather than the pump casing. The gap between the seal ring and the impeller may be kept small and constant, thus obtaining better pumping efficiency, lower operation noise and greater durability.
