    摘要: A progressive vortex pump comprises an inlet housing in contact with the pumped fluid, a pump housing connected to the inlet housing, and an outlet housing connected to the pump housing and connected to a pumping pipe. The pump housing comprises a disc-shaped rotor having a central bore and a rim with vanes. Each rotor comprises at least one through hole along the axial direction, the through hole being positioned between the central bore and the rotor rim. Advantageously, the presence of a through hole on the rotor enables, under operating conditions, fluid exchange from the posterior fluid film to the anterior fluid film, thus promoting a pressure balance between the posterior and anterior fluid films, therefore enabling the rotor to work evenly, preventing rubbing on adjacent diffusers.

    摘要: The invention relates to an impeller (1), in particular for a side channel machine, comprising blades (5) arranged distributed in the circumferential direction and formed in each case by a blade wall (6), which blades form open blade chambers (4) in a plan view onto the impeller (1), wherein a blade wall (6) in the plan view starts at a first radius dimension (r1) related to the geometrical impeller rotation axis (x), which first radius dimension (r1) corresponds to half or more than half of a second radius dimension (r2), which second radius dimension (r2) defines a circumferential rim edge (9) of the impeller (1), and wherein the radius dimension (r1) defines a radially inner boundary wall (7) of the blade chamber (4), wherein furthermore a blade wall (6) comprises an exposed upper terminating edge, which runs correspondingly radially on the inside into the inner boundary wall (7) and ends radially on the outside in plan view, wherein an imaginary connecting line (V) can be drawn between a run-in point of the terminating edge (12) into the inner boundary wall (7) and a radially outer end of the terminating edge (12) and the terminating edge runs normal to the connecting line (V) with a different offset dimension, wherein a greatest offset dimension results. For the advantageous development, in particular with regard to improved efficiency, it is proposed that the greatest offset dimension corresponds to 0.1 times or more the difference between the second (r2) and the first radius dimension (r1).

    摘要: An engaging hole-of an impeller, which receives a shaft, is formed by an impeller first planar surface, which is contactable with a shaft first planar surface, an impeller second planar surface, which is contactable with a shaft second planar surface, and an impeller first curves surface-and an impeller second curved surface, which connect between the shaft first planar surface-and the shaft second planar surface. A first groove and a second groove, which are communicated with the engaging hole, are formed in the impeller first curved surface and the impeller second curved surface, respectively. When the shaft first planar surface contacts the impeller first planar surface upon rotation of the shaft in one direction, the first groove is deformed by an applied force. Thereby, the shaft second planar surface and the impeller second planar surface contact with each other.

    摘要: An adjustable delivery volume rotary pump, including: first and second housing structures; a delivery chamber comprising a first chamber wall formed by the first housing structure, a second chamber wall formed by the second housing structure, a fluid inlet in a low-pressure region and a fluid outlet in a high pressure region; a pump wheel rotatable about a rotational axis in the delivery chamber; and a pressing device for generating pressing force. The second housing structure can be moved relative to the first housing structure from a first to a second position, against the pressing force. In the second position, a gap exists between the first and the second chamber walls and fluid can escape from the delivery chamber by bypassing the inlet and the outlet, or a circulation of the fluid which reduces the delivery rate of the rotary pump arises in the gap within the delivery chamber.

    摘要: A pump assembly comprising a stator and a rotor having vanes of opposite handed thread arrangements is described. A radial gap is located between the stator vanes and the rotor vanes such that rotation of the rotor causes the stator and rotor to co-operate to provide a system for moving fluid longitudinally between them. The operation of the pump results in a fluid seal being is formed across the radial gap. The described apparatus can also be operated as a motor assembly when a fluid is directed to move longitudinally between the stator and rotor. The presence of the fluid seal results in no deterioration of the pump or motor efficiency, even when the radial gap is significantly greater than normal working clearance values. Furthermore, the presence of the radial gap makes the pump/motor assembly ideal for deployment with high viscosity and/or multiphase fluids.

    摘要: A fuel system incorporating a boost pump unit, a boost pump unit and method of pumping fuel are provided. The fuel system and boost pump unit are preferably self-priming and do not utilize an airframe mounted pump for supplying fuel for an aircraft combustor. The boost pump unit includes a liquid ring pump and an air/fuel separator. The air/fuel separator has an inlet and first and second outlet ports. The inlet is operably fluidly coupled to an outlet of the liquid ring pump. The air/fuel separator has an arcuate flow path. The first outlet port is in fluid communication with a radially outer portion of the arcuate flow path and the second outlet port is in fluid communication with a radially inner portion of the arcuate flow path. A return line connected to the first outlet port is configured to return fuel to the liquid ring pump.
