Definitions

  • This invention relates to pumps for moving fluid and particularly, but not necessarily exclusively, to pumps having either or both of (1) fans configured to draw ambient air near axes of the fans so as to cool associated motor shaft bearings and (2) modular, multi-stage designs.
  • the pumps are especially useful as booster pumps for "pressure-side” automatic swimming pool cleaners (sometimes called “pressure-side APCs”) in liquid communication with outlets of the pumps through which pressurized water exits for return to swimming pools or spas.
  • the present invention provides alternative pump designs. Including a particularized fan design as part of the pump may be beneficial in order to draw ambient air near the fan axis where it can cool the motor shaft bearing. This air is then pushed out radially between the fan plate and motor end cap and converges with the primary fan air to then exit the fan and cool the motor. As the primary fan air and the secondary fan air meet, they both travel in a similar direction out of the fan and over the motor. All the air moving in a similar direction reduces turbulent air flow and therefore reduces noise.
  • Pump stages with each stage including an impeller and a diffuser, additionally may be formed as modules.
  • Multistage pumps allow for very high water pressure to be generated, as every stage added to a pump boosts the water pressure.
  • servicing of the inventive pump requires managing only the four assemblies rather than twelve individual parts. It thus is an optional, non-exclusive object of the invention to provide designs for pumps.
  • FIGS. 1-2 are perspective views of an exemplary pump of the present invention.
  • FIG. 3 is a perspective, partially cut-away view of the pump of FIG. 1.
  • FIG. 4 is a side elevational, partially cut-away view of the pump of FIG. 1.
  • FIG. 5 is a close-up view of the cut-away portion of the pump of FIG. 1 shown in FIG. 4.
  • FIGS. 6-7 are perspective views of a fan useful as part of the pump of FIG.
  • FIG. 8 is another perspective view of the pump of FIG. 1.
  • FIG. 9 is another perspective, partially cut-away view of the pump of FIG.
  • FIGS. 10-1 1 are perspective, partially exploded and cut-away views of stages useful as part of the pump of FIG. 1.
  • FIG. 12 is a perspective view of a stage useful as part of the pump of FIG.
  • Pump 10 Illustrated in FIGS. 1-2 is an exemplary pump 10 consistent with the present invention.
  • Pump 10 is denoted in FIG. 1 as having four stages, with such stages 14 further depicted in, e.g., FIGS. 9-10.
  • Pump 10 may include (liquid) inlet 18, (liquid) outlet 22 and, if desired, base 26.
  • Other conventional features of such a pump 10, such as a motor or drain plug 28, will be apparent to persons skilled in the relevant fields.
  • Handle 29 is configured to be grasped manually to facilitate movement of pump 10 as needed or desired.
  • handle 29 may be integrated into body 31 of the wet end of the pump 10.
  • Fan assembly 34 may comprise cover 38, whose face 42 is not solid so as to permit ambient air to enter interior 46 of the assembly 34 (see FIG. 4). As illustrated especially in FIGS. 3-5, positioned within interior 46 may be fan 50. Fan 50 is configured to rotate about motor shaft 54 (see FIG. 10) or, conceivably, about an axis aligned with such a motor shaft and coupled thereto.
  • Cover 38 preferably is removable without needing access from the bottom side of the motor to any fasteners.
  • FIGS. 1 -2 show a screw 47 present in a side 48 of cover 38. That screw 47, plus another screw on the opposed side of cover, and optionally plus clips, may function to removably connect cover 38 to other components of fan assembly 34. Screw 47 additionally may form part of ground bonding lug 49.
  • Fan 50 may, if desired, have a generally circular cross-section and define front 58 (oriented toward inlet 18), rear 62 (oriented toward cover 38), and periphery 64. Fan 50 additionally includes a central opening 66 for receiving motor shaft 54 or similar. These features are depicted at least in FIGS. 3, 6, and 7.
  • FIG. 6 illustrates seven blades 70 extending from rear 62, each having a first end 78 adjacent central opening 66 and a second end 82 adjacent (outer) periphery 64. More or fewer than seven blades 70 may be present, however, if appropriate or desired. Also illustrated are seven pass-through holes 74 from rear 62 to front 58, each disposed between adjacent blades 70 and generally near central opening 66. Again, however, more or fewer holes 74 may be present, although in some versions the numbers of blades 70 and holes 74 preferably are equal.
  • blades 83 Depicted in FIG. 7 as present on front 58 are blades 83. Like blades 70, blades 83 each may have a first end 84 adjacent central opening 66 and a second end 85 adjacent periphery 64. Advantageously, blades 83 may have less depth than blades 70.
  • FIG. 5 Operation of a motor of pump 10 rotates motor shaft 54, in turn rotating fan 50.
  • fan 50 As fan 50 rotates, it draws ambient air through cover 38 into interior 46 of fan assembly 34.
  • Arrows A of FIG. 5 detail the flow direction of this air as it approaches face 42.
  • blades 70, together with holes 74 create two air-flow streams within assembly 34, a nominally "primary” stream 78 that does not pass through holes 74 and a "secondary" stream 82 that does pass through holes 74.
  • Drawing ambient air through fan 50 via holes 74 better cools the bearing for motor shaft 54 and helps reduce noisy air-recirculation areas that would otherwise exist between fan 50 and face 42. This latter advantage is particularly true when the drawn air is then forced out past the motor of pump 10 (see arrows B of FIG. 5).
  • FIGS. 9-10 and 12 are modular stages 14 of pump 10.
  • the cutaway drawing of FIG. 9 illustrates four such stages 14 positioned adjacent each other (or "stacked," using terminology of the Stiles, Jr. application).
  • Each stage 14 may include at least an impeller 86 and a diffuser 90; like fan 50, stages 14 may be positioned so as to rotate about motor shaft 54 (or an axis aligned with and coupled thereto).
  • a stage 14 may comprise three parts—two (90A and 90B) clipping or otherwise connecting together to form diffuser 90 and the third being impeller 86 fitted between parts 90A and 90B.
  • the stage 14 closest to inlet 18 further may include an O- ring to enhance mechanical sealing there.
