摘要： An impeller for centrifugal pumps has a first disk element, functionally arranged toward the inlet, which is coaxial to and faces a second disk element, which is functionally arranged toward the delivery and is connected rigidly to the first disk element by virtue of a series of angularly spaced vanes and is provided centrally with a means for fixing to a transmission shaft. The particularity of the present invention resides in that the impeller includes a series of openings formed in the substantially peripheral region of the second disk element, between pairs of adjacent vanes, substantially at the areas subjected to the greatest axial thrust.

摘要： The present invention relates to a volute pump for delivering a liquid containing fibrous substances. The volute pump according to the present invention includes an impeller (1) rotatable together with a rotational shaft (11), and an impeller casing (5) having a suction port (3) and a volute chamber (7). A groove (18), extending from the suction port (3) to the volute chamber (7), is formed in an inner surface of the impeller casing (5). The impeller (1) includes a hub (13) to which the rotational shaft (11) is fixed, and a sweep-back vane (2) extending helically from the hub (13). The sweep-back vane (2) includes a leading edge portion (2a) extending helically from the hub (13), and a trailing edge portion (2b) extending helically from the leading edge portion (2a). The leading edge portion (2a) has a front-side curved surface (2e) extending from an inner end (2c) to an outer end (2d) of the leading edge portion (2a).

摘要： An impeller assembly for centrifugal pumps has two disk members that have different diameters, are arranged coaxially to a rotation axis and face each other so as to form an interspace; blades are radially arranged in the interspace; the two disk members are also centrally provided with a fastening means for fastening to a transmission shaft, which rotates about the rotation axis. The particularity of the present invention resides in having contoured vanes that protrude radially from the peripheral region of the disk member that has the smallest diameter and are arranged substantially at the blades.

摘要： A district assisting system for making a plan of a waste disposal network, Icons (I1 to I3) indicating the kinds of waste are displayed on a monitor screen. The operator selects, e.g., a gasification melting furnace from a disposal facility item box (W2), creates an icon (I4) in a plan sheet box (W1), and draw a line (L1) linking the icon (I1) to the icon (I4). When the operator clicks the icon (I4), the kinds and amounts of residual and valuable substances produced when combustible waste is processed in a gasification melting furnace are displayed. The operator selects the next disposal facility according to the displayed unconnected residual substances, creates an icon of the selected facility on the monitor screen, and links the icon to the icon (I4). Thus a plan is completed.
