    摘要： The present disclosure provides a two-stage cavitation generator for organic wastewater treatment, including a shrouded impeller, a stator, and a rotor. The shrouded impeller includes a front cover plate, blades, and a rear cover plate. Several blades are evenly distributed between the front cover plate and the rear cover plate. A working surface of the blade is an arc surface, and a back of the blade protrudes locally, so that a flow channel between the back of the blade and a working surface of its adjacent blade is narrowed locally, forming a throat structure. An outlet of the shrouded impeller is provided with the stator and the rotor, and the stator is located at an outer edge of the front cover plate and fixed on an inner wall of a volute. The rotor is mounted on the rear cover plate.

    摘要： An impeller wheel, in particular for a centrifugal pump, has in at least one side view perpendicular to a rotary axis outer contour that is spaced apart radially from the rotary axis, the outer contour comprising a first contour line which is inclined relative to the rotary axis by a first angle, and comprising a second contour line which directly follows the first contour line and is inclined relative to the rotary axis by a second angle, the second angle being by at least 0.05° and maximally 2° smaller than the first angle.

    摘要： A centrifugal pump includes a motor having a shaft, and an impeller engaged with an end portion of the shaft such that a rotation of the impeller relative to the shaft is limited. The impeller includes a main panel engaged with the shaft, a plurality of passage walls extending from the main panel in an axial direction, a side panel in contact with end surfaces of the passage walls that face away from the main panel, the side panel having an inflow opening at a radially center part, and a fluid passage that is defined by the passage walls adjacent to each other in a circumferential direction, the fluid passage communicating with the inflow opening. The side panel includes an engagement portion configured to be engaged with a fixation jig that limits a rotation of the impeller during fixing the impeller to the shaft by screwing a nut.

    摘要： A blower wheel for use in a blower assembly is disclosed, wherein the blower wheel includes a hub, a concentrically arranged outer ring, and an array of spaced apart blades arranged on an outer periphery of the hub and extending between the hub and the outer ring. The hub includes a wave configuration formed therein. The wave configuration includes an annular array of crests and an annular of troughs alternately formed in at least one of an outer surface and an inner surface of the hub. The hub may also include an annular array of support members formed on the inner surface thereof.

    摘要： A heat pump for a dishwasher includes a pump casing, a motor (20) having a rotatable shaft 201 extended into a chamber of the pump casing, an impeller (30) disposed within the chamber, a heating assembly (40) and a pressure switch assembly (50). The heating assembly includes a heating pipe (41) disposed in the chamber, a fuse (42), and a heater wire disposed in the heating pipe. The heating pipe includes an arc-shaped portion (411), and first and second linear portions (412, 413). The fuse is disposed in at least one of the first and second linear portions and is remote from the arc-shaped portion, and an extending part (302) of the impeller is encircled by and spaced apart from the arc-shaped portion. A dishwasher including the heat pump is also provided.
