摘要： The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10′, 11) of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.

摘要： An inducer and a submersible pump for pumping a slurry comprising solids and viscous fluids, the inducer mountable to the pump's drive shaft adjacent to and immediately upstream of an impeller mounted on said shaft. The inducer comprises a hub, two to four inducer blades extending outwardly from and wrapping helically around the hub, the hub and the inducer blades defining a plurality of channels A trailing edge of each inducer blade is positioned snugly adjacent to and in fluidical alignment with a leading edge of a corresponding impeller blade when the inducer is mounted on the drive shaft of the pump, such that a velocity curve of the slurry is smooth as the slurry travels from a leading edge of the inducer blades to the leading edge of the impeller blades.

摘要： Radial pump (1) comprising a stator (3) comprising an external stator (30) and an internal stator (32) defining an annular cavity (11) therebetween, and an impeller (5) rotatably housed between said stators (30; 32). The suction (7) is fashioned at a central portion of the internal stator (32), whereas the delivery (9) is fashioned at a radially external peripheral portion of the external stator (30). The impeller (5) comprises a plurality of deformable vanes (50, 51, 52) movable inside the annular cavity (11) and in slidable contact with the internal surface of the external stator (30). In every position of the impeller (5) with respect to the stator (3) at least two deformable vanes (51) are sealed in the portion of the annular cavity (11) between the suction (7) and the delivery (9) to isolate the delivery (9) from the suction (7). The impeller (5) is rotatable about a central internal axis (Al) offset with respect to the central external axis (AE) of the external stator (30), where the rotational eccentricity of the impeller (5) with respect to the external stator (30) determines a deformation of the deformable vanes (50, 51, 52) that contributes to the generation of flow rate of said pump (1).

摘要： An impeller for use in an aquarium filter pump includes a shaft and a plurality of impeller blades radially extending from the shaft. Each of the impeller blades includes opposite blade faces. A depression is in each of the blade faces and aids in pushing the water. The depression can be a variety of shapes and can have its deepest portion along one of the edges of the blade.

摘要： An impeller includes a hub, and a plurality of blades supported by the hub, the blades being arranged in at least two blade rows. The impeller has a deployed configuration in which the blades extend away from the hub, and a stored configuration in which at least one of the blades is radially compressed, for example by folding the blade towards the hub. The impeller may also have an operational configuration in which at least some of the blades are deformed from the deployed configuration upon rotation of the impeller when in the deployed configuration. The outer edge of one or more blades may have a winglet, and the base of the blades may have an associated indentation to facilitate folding of the blades.

摘要： A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

摘要： A centrifugal blower includes: a centrifugal fan having plural blades arranged around a fan axis and a separation plate to blow out air in a radial direction after being sucked from one side in an axial direction; a fan casing housing the centrifugal fan; a partition plate that defines a first air passage and a second air passage arranged on the other side of the first air passage in the axial direction; and a separation cylinder arranged inside the plural blades in the radial direction. The separation cylinder expands in the radial direction as extending toward the other side in the axial direction, and is shaped to extend outward in the radial direction obliquely to the axial direction at the other end position of the separation cylinder positioned at the other end in the axial direction.

摘要： A variable impeller for a pump is proposed. The variable impeller includes a hub to which a shaft is mounted, a plurality of vanes radially arranged around the hub outward from the hub, and extension wings tightly locked to the plurality of vanes and extending length of each of the vanes. The length of the vane is adjusted in response to the pumping head that is changed by a flow rate of fluid, the pump is operated within a high efficiency section, an expensive impeller rotation speed control device is not required, and energy is reduced by reducing power consumption of the pump. In addition, during the work of changing the pumping head, the replacement of the extension wings may be quickly completed while only a part of a pump housing is opened to expose only the impeller without separating the entire assembly of the impeller from the pump.
