摘要： A fan device (1) includes an impeller (10) rotating around a central axis and a motor (20) disposed farther downward than the impeller (10). The impeller (10) includes a base unit (11) enlarged downward and plural blades (12) disposed on a peripheral surface of the base unit (11). Upper portions of the blades (12) are positioned at a leading end of a rotating direction with respect to lower portions. In an outer end portion on a front surface of each blade (12) at the leading end of the rotating direction, a radial-direction component of a normal unit vector of an upper end portion of the blade (12) is smaller than that of a lower end portion, assuming that an outer peripheral side of the blade (12) is a positive direction. A thickness of a root of the lower end portion is larger than that of the upper end portion.

摘要： The present invention relates to a multistage centrifugal pump design, which has the diffusers, impellors, and a shaft, inserted within a high pressure housing, such that this assembly is fully enclosed within the housing, and the housing is of sufficient strength to be suitable for safe pressure containment of the fluids being pumped. This invention describes the technical details used to reconfigure the multistage centrifugal pump design to increase the discharge pressure capabilities higher than the 6,000 psig of current designs.

摘要： A regenerative pump comprises a housing (1), an impeller (5) within the housing (1) having a plurality of vanes (13) spaced angularly around the axis of rotation of the impeller (5) and accommodated within a flow channel (4) within the housing (1) extending between an inlet (19) and an outlet (20), a flow stripper (17) located between the inlet (19) and outlet (20) and through which the vanes (13) pass, a fluid flow loop (27) in the stripper (17) which intersects the path of rotation of the vanes (13), and control means (26) to control the flow of fluid through the loop (27) so as to vary the annular motion transferred to the fluid downstream of the stripper (17), thereby to selectively vary the output of the pump. The flow stripper (17) comprises a land portion (21) upstream of the loop (27) which restricts direct fluid flow through the stripper (17), and the control means (26) comprises valve means which controls a supply of fluid to the upstream end of the loop (27). The supply of fluid to the loop (27) is tapped from a high pressure region of the pump possibly via a second fluid flow loop (22) in the stripper (17).

摘要： A regenerative pump comprises a housing (1) an impeller (5) having a plurality of vanes (13) spaced angularly around the axis of rotation of the impeller (5) within a flow channel (4) extending between an inlet (19) and outlet (20), a flow stripper (17) located between the inlet (19) and outlet (20) and through which the vanes pass, a second fluid inlet (33) that opens into the flow channel (4) between the inlet (19) and outlet (20), and control means (34) to control the supply of fluid selectively to one or the other, or one or both of said fluid inlets (19,33), thereby to vary the output of the pump. The stripper (17) incorporates a fluid flow loop (22) which intersects the path of rotation of the vanes (13). The first fluid inlet (19) is preferably spaced downstream of the stripper (17), for example, within an angular range of 15° to 90° from the fluid exit port (29) of the stripper (17), and preferably 45° to 75° from the exit port (29).
