    摘要: A centrifugal pump has one or more pumping stages within a pump body. A drive shaft 18 drives an impeller 26 having a central portion 30 and an outer periphery 32. Rotor vanes 34 radiate from the central portion 30 to urge a fluid to be pumped radially outwards. A shroud 38 is connected to the impeller 26 for rotation therewith. The shroud 38 has an outer peripheral portion 40 extending beyond the outer circular periphery 32 of the impeller 26 in overlapping relationship and is configured to deflect the fluid towards an outlet 24. A diffuser 20 is located opposite to the impeller 26 and has a stator assembly including passages 46 configured to direct the fluid from the outer peripheral portion of the shroud 40 towards the outlet 24.

    摘要: The invention concerns an impeller for pumps, turbines, fans etc of a so-called closed type.
    The impeller includes cover discs (2) and (3) respectively and a number of vanes (5) arranged between said cover discs. In order to reduce the secondary flows within the impeller the secants between the suction side of the vane and the cover discs are displaced with regard to the secants at the pressure side of the vane, thus obtaining an impeller which is rotationally non-symmetrical.

    摘要: Disclosed is a water pump including: a driving shat configured to be rotated by an external driving force; an impeller configured to be rotated by being connected to the driving shaft; and a cover frame including a main frame having an accommodation space in which the impeller is accommodated, formed therein, a suction pipe, which communicates with one side of the main frame and through which a fluid is suctioned into the accommodation space, and a barrier wall that extends from the suction pipe and disposed at one side between the main frame and the impeller. In the water pump according to the present invention, the barrier wall is added between the main frame and the impeller so that foreign substances can be prevented from being introduced between the impeller and the main frame. Also, in the water pump according to the present invention, an outer end of an impeller base is inclined so that the foreign substances can be smoothly discharged from the water pump.
