摘要： To provide a can manufacturing pump impeller in which a stress of a base portion of a blade is prevented from increasing while improving the strength of a joint portion of a hub and a boss. In order to reinforce a joint portion of a hub and a boss, a plate is jointed to the inside of an impeller. In order not to overlap a base portion of a blade and the plate with each other on the hub, an opening portion is provided in the plate around the base portion of the blade on the hub. As a shape of the opening portion, a semicircular shape, a semielliptical shape, a rectangular shape, or a trapezoidal shape can be selected. Further, as a plate shape, a flat plate structure, a shell structure, or a curved structure can be selected.

摘要： An underground water channel is provided in an underground of a large depth, and rain water and the like flow into this underground channel from flood control channels, conduits and rivers through vertical shafts. A pump well of a pump station is connected to a downstream end of the underground channel, and water flowing into the pump well is discharged by a pump to a discharge tank. The pump is disposed generally at a medium water level of the underground channel, and a lowest water level L.W.L enabling draining is the medium water level of the underground channel. In an open channel flow operation of an open channel-closed channel mixed flow operation, water level of the underground channel is maintained at the lowest water level L.W.L, so that the underground channel is in an open channel condition. In the closed channel flow operation, the underground channel is fully filled with water, and further water level rises into the vertical shafts, so that the underground channel is in a closed channel condition. By changing an outflow factor in accordance with rainfall patterns, the rate of flow into the vertical shafts can be accurately estimated, so that the large-depth underground drainage facility can be run in a stable manner.

摘要： A centrifugal compressor comprises a centrifugal impeller and a vaned diffuser. The diffuser includes a pair of diffuser plates and a plurality of guide vanes arranged between the pair of diffuser plates in a circular cascade manner. The guide vanes are equal in leading-edge radius to each other, but are different in length from each other. At least one short guide vane is arranged between the adjacent long guide vanes. The total number of the guide vanes is more than the number of blades of the impeller. A throat is formed in only a part of flow passages between the guide vanes.

摘要： A prewhirl type inlet casing for inducing a spiral stream in fluid comprising a suction passage arranged on an upstream side, being orthogonal to a rotary shaft of fluid machinery, and an internal passage connected to the suction passage, the internal passage being formed in a spiral shape so as to induce a swirl stream orthogonal to the rotary shaft in the fluid. A guide vane is provided in the fluid passage in the inlet casing. The guide vane has a rectifying function capable of distributing flow rates in the swirl stream of the fluid in the internal passage between the swirl center side and the swirl outer peripheral side and has a rectifying function capable of causing the fluid to deflect into the swirling direction of the swirl stream induced by the internal passage. With these rectifying functions, a rectified swirl stream can be easily created in the in internal passage so as to prevent occurrence of a deviation of a cavitations inducing zone. With this configuration, it is possible to effectively prevent occurrence of the deviation of the cavitations inducing zone in order to aim at simplifying the configuration of the internal passage.
