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: 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: Embodiments of the invention are directed to a rotor for a molten metal pump and a molten metal pump including the rotor. The rotor has a main body and a top comprised of a material that is at least twice as hard as the main body. The top, among other things, may form a first portion of each rotor blade wherein the first portion directs molten metal into a pump chamber or other structure in which the rotor is mounted.

摘要: Extracorporeal circuit devices can be used for on-pump open-heart surgery to support surgical procedures such as coronary artery bypass grafting. In some cases, a centrifugal pump is used as part of an extracorporeal circuit. Centrifugal pump heads are described herein that induce flow on two sides of an impeller plate, and that can be conveniently mechanically assembled.
