Description

Technical Field

[0001] This utility model relates to the field of water pumps, and more specifically, to an integrated water pump. Background Technology

[0002] In pump structural design, the vortex chamber shell must simultaneously meet the dual requirements of hydrodynamic performance and mechanical structural strength. Traditional vortex chambers typically employ an orthogonal radial stiffening network, which, while improving radial stiffness, has the following inherent drawbacks:

[0003] 1. Stiffness-flexibility contradiction: Radial ribs significantly weaken circumferential ductility while suppressing radial deformation, leading to circumferential stress concentration under high-speed conditions;

[0004] 2. Vibration transmission and amplification: Regular cavities formed by orthogonal ribs are prone to resonance at specific frequencies, such as impeller frequencies, and the measured vibration energy spectrum shows sharp peaks;

[0005] 3. Manufacturing process limitations: Complex ribbed structures require multi-directional core-pulling molds, which make demolding difficult and easily lead to casting defects. Utility Model Content

[0006] The purpose of this invention is to provide an integrated water pump that can overcome the above-mentioned problems.

[0007] The embodiments of this utility model are implemented as follows:

[0008] An integrated water pump, comprising:

[0009] The eccentric vortex chamber has its axis lower than the pump body mounting surface and has a sunken cylindrical structure.

[0010] The integrated reinforcing rib assembly includes:

[0011] Radial main ribs: 6-10 quadrilateral cross-section stiffeners evenly distributed along the circumference of the outer wall of the vortex chamber, with the eccentric point of the vortex chamber as the center.

[0039] First Embodiment

[0040] Please refer to Figure 1 and 2 This embodiment provides an integrated water pump, including an eccentric vortex chamber 110, an integrated reinforcing rib assembly 120 disposed at the closed end of the eccentric vortex chamber 110, and a double support base 130 disposed at the bottom of the eccentric vortex chamber 110.

[0041] The eccentric vortex chamber 110 has its axis lower than the pump body assembly surface and has a sunken cylindrical structure. One end of the chamber has a closed surface for assembling the pump body, and the other end has an open surface for connecting the water inlet shell. The top has an opening for connecting the water outlet.

[0042] The integrated reinforcing rib assembly 120 includes radial main ribs 121 and spiral connecting ribs 122. The radial main ribs 121 are 6-10 quadrilateral reinforcing ribs evenly distributed circumferentially along the outer wall of the vortex chamber, centered on the eccentric point of the vortex chamber. In this embodiment, the reinforcing ribs are isosceles trapezoidal ribs with rounded corners.

[0043] The spiral connecting rib 122 extends outward from the center in a spiral shape, and is connected to each radial main rib 121 through a detachable connection or integral molding method. This addresses the contradiction between radial stiffness and circumferential flexibility in traditional radial ribs. Radial ribs primarily resist radial deformation but weaken circumferential ductility, while the spiral direction of the spiral rib can simultaneously bear stress in both directions, thus improving stiffness. Secondly, it addresses the vibration transmission path issue: traditional orthogonal rib meshes amplify vibrations at specific frequencies, while the continuous gradient structure of the spiral rib broadens the vibration spectrum, reducing peak energy by more than 15dB, which is particularly critical for high-speed pumps. Furthermore, the spiral rib is actually a topology-optimized variant of the radial rib; in the mold, only straight ribs need to be replaced with spiral grooves, maintaining the same manufacturing cost but increasing the yield. Moreover, the experimental results show that the ZL114A aluminum alloy has better fluidity to adapt to the spiral channel.

[0044] According to the simulation, the optimal pitch P = 0.25D-0.3D is needed to balance stress and flow field interference, where D is the diameter of the vortex chamber.

[0045] The radial section of the spiral connecting rib 122 is an isosceles trapezoidal structure, and the thickness of the bottom root of the radial main rib 121 is 1.2-1.5 times the thickness of the vortex chamber wall, and extends to the outer edge of the vortex chamber.

[0046] The helix angle β of the spiral connecting bar 122 satisfies: 15°≤β≤25°. The intersection of the spiral connecting bar 122 and the radial main bar 121 is bidirectionally interlocked, and the interlocking width is 0.2 to 0.4 times the thickness of the bar.

[0047] In this embodiment, a detachable connection is used as an example. Of course, a spiral connecting rib 122 integrally formed with the pump body can also be used directly. It can also serve as a natural draft track, allowing complex structures to be demolded in one go, and the spiral path forces casting shrinkage cracks to extend along the spiral line, avoiding radial through cracks.

[0048] In this embodiment, if a detachable connection method is used, the corresponding radial main rib 121 is provided with a through hole for the spiral connecting rib 122 to pass through. The outer edge of the spiral connecting rib 122 is provided with a connecting hole assembly position 123 that connects to the radial main rib 121 at intervals. The radial main rib 121 is provided with a threaded groove 124 at the corresponding position to achieve detachable connection. The connecting hole assembly position 123 is a flexible piece with a through hole.

[0049] In this embodiment, the integrated reinforcing rib assembly 120 has a stepped reinforcing ring array at its center, including:

[0050] At least three concentric reinforcing rings 125 with progressively increasing diameters, and spiral connecting ribs 122 extending spirally from the outermost concentric reinforcing ring.

[0051] Circumferential secondary reinforcement 126 is provided on the outer wall of each ring;

[0052] The radial block connector 127 connecting adjacent rings has its axial projection at an angle of 30°-60° to the radial main rib 121.

[0053] The height H1 from the upper wall to the axis and the height H2 from the axis to the lower wall of the eccentric vortex chamber 110 satisfy H1:H2=3-4:2.

[0054] The double-support base 130 is symmetrically located at the bottom of the vortex chamber and is integrally formed by radial main ribs 121 extending outward. Its support surface is a trapezoidal structure with anti-slip texture.

[0055] The integrated water pump is made of ZL114A high-strength aluminum alloy through a single casting.

[0056] In summary, the core innovation of the water pump structure in this embodiment lies in:

[0057] 1. Submerged eccentric vortex chamber 110: The axis is lower than the pump body assembly surface, forming a golden ratio of upper wall height H1 to lower wall height H2 (H1:H2=3-4:2), and the inlet pre-swirl is optimized through asymmetric flow channel design;

[0058] 2. Bionic composite rib mesh 120: The topological configuration integrates radial main ribs 121 and spiral connecting ribs 122, wherein: 6-10 radial ribs with rounded isosceles trapezoidal cross sections are evenly distributed circumferentially, and the root thickness is 1.2-1.5 times the vortex chamber wall thickness. The spiral ribs extend spirally with a helix angle β=15°-25°, and the pitch P is determined to be 0.25D-0.3D by fluid-structure interaction simulation, where D is the vortex chamber diameter;

[0059] 3. Dual-path stress transfer mechanism: The spiral ribs, through a bidirectional interlocking structure, have a width of 0.2-0.4 times the rib thickness, and the radial ribs intersect, which increases the radial stiffness by 38% while increasing the circumferential strain tolerance by 25%.

[0060] 4. Spectral vibration suppression: The continuous and gradual change characteristics of the spiral ribs disperse vibration energy across a wide frequency band, and experiments have shown that peak noise can be reduced by >15dB.

[0061] 5. Innovative casting process: The spiral ribs also serve as draft guides, enabling one-time molding of the stepped reinforced ring array 125 / 126 / 127, and guiding shrinkage cracks to propagate harmlessly along the spiral line;

[0062] 6. By integrally casting the dual-support base 130 with ZL114A high-strength aluminum alloy, a synergistic leap in mechanical properties and fluid efficiency is ultimately achieved.
