    1470832 Helico-centrifugal pumps ITT INDUSTRIES Inc 2 May 1974 [9 May 1973] 19306/74 Heading F1C In a pump, e.g. a submersible pump, comprising a housing containing a motor-driven impeller 5 and a stationary diffuser assembly 13, 14, the diameter Di of the impeller hub at its inlet end is between 40 and 80% of the maximum diameter D2 of the impeller, the angles between a plane normal to the impeller axis and the inlet and outlet edges of the impeller blades 9 are 10 to 30 degrees and 15 to 90 degrees respectively and the angles between the plane and the inlet and outlet edges of the diffuser blades 14 are 30 to 60 degrees and 75 to 105 degrees respectively. The impeller blades have substantially straight leading portions and curved trailing portions and define helical flow-paths. The inlet edges of the blades may be radial or backwardly curved and the radially outer edges 10 may be parallel to the impeller axis.

    one
    The invention relates to pump engineering, in particular, to the design of an axial pump, and can be used in the design of pumps with axial fluid flow for general industrial purposes.
    A pump is known, comprising a housing with a guide vane and a rotor with blades mounted thereon and a rotational drive driving til.
    The disadvantage of this pump is
    viscous efficiency.
    P1a most close to the invention is a vpnvts axial pump, mainly submersible, comprising a housing with an associated1-15 | the expanding and suzhak tsimis sections and, respectively, the impeller located in them with a sleeve and a diffuser with a fairing, the sleeve and the fairing have a variable diameter with a maximum value in the interface area of the body sections and are equipped with curvilinear blades inclined to the side, opposite to the rotation of the working knee 2.
    The disadvantages of the known pump are low efficiency and low durability.
    The purpose of the invention is to increase efficiency and durability.
    The goal is achieved by the fact that the outer diameter of the sleeve on the inlet side amounts to 4O-8O% of the maximum impeller diameter, and the input and output edges of the blades of the latter and the diffuser are located in planes perpendicular to the axis of the pump and forming corners with tangents to the blade surfaces equal to, respectively, 15, 45, 45 and 85 °.
    FIG. I shows the proposed pump, a longitudinal section in FIG. 2 is the same view from the drive side, w FIG. 3 - impeller, longitudinal section; in fig. 4 - scan of the impeller.
    The axial pump comprises a housing I with adjoining expanders 5 and more narrowing sections 2 and 3 and, respectively, impeller 4 located in them with the 3rd sleeve 5 and 4Sor 6 with obgegegel 7 and the nozzle 5 and obgegegel 7 have a maximum diameter in the counterpart zone housing sections I, and are equipped with curviline blades 8 and 9, inclined in the direction opposite to the rotation of the impeller 4. The outer diameter of the sleeve 5 on the inlet side is 4O-8O% of the maximum diameter of the Impeller 4, and the input and outputthe edges 10 and 11 of the blades 8, as well as the inlets and outlets KpoMioi 12 and 13 of the blades 9 of the diffuser 6 are located in planes perpendicular to the pump axis and forming, respectively, 15, 45, 45 85 axes to the surface of the blades, respectively. the pump works as follows. The fluid flow entering the impeller 4 acquires the energy of motion. from the rotating impeller 4, and the location of the edges 1O and 11 -; blades 8 ensures minimal hydraulic input and output losses. The blades 9 provide continuation of the inlet channel for the movement of fluid in the axial direction, and the arrangement of their edges 12 and 13 creates conditions for reducing losses at the inlet and outlet of the diffuser 6.

    13 54 Thus, the proposed pump design ensures the alignment of the transaxle and durability. Claims of the invention: An axial pump, preferably a submersible pump, comprising a housing with a mating expanding and constricting Tsimis 1,. sections and an impeller with a sleeve and a diffuser with a fairing, respectively, the sleeve and the fairing have a variable diameter with a maximum value in the junction area of the housing sections, and are equipped with Curvilinear blades inclined in the direction opposite to the rotation of the worker. KOJKca, characterized in that, in order to increase the KPD and durability, the outer diameter of the hub from the inlet is 4O-8O% of the maximum diameter of the impeller, and the input and output edges of the blades of the last and diffuser are placed in planes perpendicular pump axes and specimens with tangents to the surfaces of the blades are angles equal, respectively, to 15, 45, 45 and 85.
