A pump assembly 100 for a water treatment device according to an embodiment of the present invention is described below with reference to fig. 1-5.
As shown in fig. 1 to 5, a pump assembly 100 for a water treatment apparatus according to an embodiment of the present invention may include a pump body 1, a water inlet joint (not shown), a water outlet joint (not shown), a housing 2, and a first damper 3. Wherein, the pump body 2 can be a booster pump.

Therefore, after the pump body 1 is installed in the casing 2, the water inlet joint is connected with the water inlet 11 through the first through hole 21, and the water outlet joint is connected with the water outlet 12 through the second through hole 22.

Therefore, when the pump body 1 works and vibrates, the first damping body 31 can deform along the axial direction of the pump body 1 (for example, referring to fig. 1, the axial direction of the pump body 1 is the up-down direction), and the connecting sleeve 32 deforms along the radial direction of the pump body 1, so that the vibration energy in the axial direction and the radial direction of the pump body 1 can be absorbed, thereby reducing the vibration transmission from the pump body 1 to the casing 2 in the axial direction and the radial direction, and being beneficial to improving the radiation noise of the casing 2, in addition, by sleeving the connecting sleeve 32 on the outer circumferential surface of the pump body 1, the first damping member 3 can be fixed on the pump body 1 without using a connecting fastener, thereby avoiding the traditional damping foot pad from being fixed on the pump body 1 and the casing 2 through the connecting fastener, because the traditional connecting fastener is omitted between the pump body 1 and the casing 2, thereby avoiding the rigid vibration transmission between the pump, and further contributes to further improvement of the radiation noise of the housing 2. For example, the connection sleeve 32 is in interference fit with the pump body 1.
According to the pump assembly 100 for the water treatment device of the embodiment of the invention, the first damping member 3 is arranged at the bottom of the pump body 1 and is positioned in the housing 2, the first damping member 3 comprises the first damping body 31 and the connecting sleeve 32, the first damping body 31 is positioned between the bottom wall of the housing 2 and the bottom surface of the pump body 1, and the connecting sleeve 32 is sleeved on the outer circumferential surface of the bottom of the pump body 1, so that when the pump body 1 works and vibrates, the first damping body 31 deforms along the axial direction of the pump body 1, and the connecting sleeve 32 deforms along the radial direction of the pump body 1, and can absorb the vibration energy in the axial direction and the radial direction of the pump body 1, thereby reducing the vibration transmission from the pump body 1 to the housing 2 in the axial direction and the radial direction, and being beneficial to improving the radiation noise of the housing 2, in addition, by sleeving the connecting sleeve 32 on the outer circumferential surface of the pump body 1, the first damping member 3 can be fixed, avoided traditional damping callus on the sole to fix on pump body 1 and casing 2 through connecting fastener, because traditional connecting fastener has been saved between pump body 1 and the casing 2 to avoided the rigid vibration transmission between pump body 1 and the casing 2, and then be favorable to further improving the radiation noise of casing 2.
In some embodiments of the present invention, as shown in fig. 1 and 2, the first shock-absorbing body 31 is formed at the bottom surface thereof with a plurality of protrusions 33. Therefore, the contact area between the first damping body 31 and the bottom wall of the housing 2 can be reduced, which is beneficial to reducing the vibration transmission from the pump body 1 to the housing 2 in the axial direction, and is further beneficial to improving the radiation noise of the housing 2.
In some embodiments of the present invention, and as illustrated with reference to fig. 1, a pump assembly 100 comprises: and the second damping piece 4 is cylindrical, the second damping piece 4 is sleeved on at least one of the water inlet joint and the water outlet joint, and the second damping piece 4 is positioned in the first through hole 21 and/or the second through hole 22. The pump assembly 100 may include a second damping member 4, wherein the second damping member 4 is cylindrical and is sleeved on the water inlet joint, and the second damping member 4 is located in the first through hole 21; the pump assembly 100 may also include a second damping member 4, the second damping member 4 is cylindrical and is sleeved on the water outlet joint, and the second damping member 4 is located in the second through hole 22; or two second damping pieces 4 can be provided, the two second damping pieces 4 are cylindrical and are respectively sleeved on the water inlet joint and the water outlet joint, and the two second damping pieces 4 are respectively positioned in the first through hole 21 and the second through hole 22. Therefore, when the pump body 1 vibrates, the vibration transmission from the pump body 1 to the housing 2 can be reduced by the vibration absorption of the second vibration absorbing member 4.
alternatively, as shown with reference to fig. 1, the pump assembly 100 comprises: the third damper 5, the third damper 5 include third damper body 51 and establish the damping sleeve 52 on third damper body 51, and damping sleeve 52 encircles the periphery setting of third damper body 51, and third damper body 51 is located between the roof of casing 2 and the top surface of the pump body 1, and second damper 4 establishes on third damper body 51, and damping sleeve 52 cover is established on the outer peripheral face of the pump body 1. Therefore, when the pump body 1 works and vibrates, the first damping body 31 and the third damping body 51 deform in the axial direction of the pump body 1, and the connecting sleeve 32 and the damping sleeve 52 deform in the radial direction of the pump body 1, which is beneficial to further reducing the vibration transmission from the pump body 1 to the housing 2 in the axial direction and the radial direction, thereby further improving the radiation noise of the housing 2.
In some alternative embodiments of the present invention, as shown in fig. 3, a plurality of first grooves 53 are formed on the outer circumferential surface of the damping sleeve 52. This reduces the contact area between the outer peripheral surface of the damper sleeve 52 and the inner peripheral surface of the housing 2, thereby reducing the transmission of vibration from the damper sleeve 52 to the housing 2.
Alternatively, as shown in fig. 3, the first grooves 53 are plural and are provided at intervals in the circumferential direction of the damper sleeve 52, each of the first grooves 53 includes a main body section 531 and an extension section 532, the main body section 531 axially penetrates through both axial end surfaces of the damper sleeve 52 (for example, refer to the upper end surface and the lower end surface of the damper sleeve 52 shown in fig. 3), and the extension section 532 is communicated with the main body section 531 and is adjacent to the top of the damper sleeve 52 (for example, refer to the upper end of the damper sleeve 52 shown in fig. 3). This is advantageous in that the contact area between the outer peripheral surface of the damper sleeve 52 and the inner peripheral surface of the housing 2 is further reduced, and the transmission of vibration from the damper sleeve 52 to the housing 2 is further reduced.
In some alternative embodiments of the invention, as shown in figure 3, the second cushioning member 4 is formed integrally with the third cushioning member 5. Therefore, the second damping piece 4 and the third damping piece 5 are convenient to form and simple to manufacture, redundant assembly parts and connection procedures are omitted, and the assembly efficiency between the second damping piece 4 and the pump body 1 and between the third damping piece 5 and the pump body 1 are greatly improved.
in some embodiments of the invention, the first shock absorbing member 3 is a rubber member. Thereby, the vibration damping and energy absorbing capacity of the first vibration damper 3 is advantageously enhanced, thereby reducing the transmission of vibration of the pump body 1 to the housing 2.
In some embodiments of the invention, the peripheral wall of the housing 2 has a thickness in the range of 5-6 mm. Thereby, the sound insulation effect of the case 2 is advantageously further enhanced. For example, the thickness of the peripheral wall of the housing 2 may be 5mm, 5.5mm, 6 mm.
in some embodiments of the present invention, the pump assembly 100 comprises: the noise reduction piece 6 is cylindrical and is sleeved on the periphery of the pump body 1, the noise reduction piece 6 is arranged in the shell 2 and is spaced from the shell 2 in the radial direction, the noise reduction piece 6 is connected with the shell 2, a resonant cavity is defined between the noise reduction piece 6 and the shell 2, a plurality of noise reduction holes 61 are formed in the peripheral wall of the noise reduction piece 6, each noise reduction hole 61 penetrates through the noise reduction piece 6 along the thickness direction of the peripheral wall of the noise reduction piece 6, the first damping piece 3 is located between the pump body 1 and the noise reduction piece 6, and the outer peripheral surface of the connecting sleeve 32 is suitable for being abutted against the inner peripheral surface of the noise reduction piece 6. Therefore, the resonance cavity defined between the noise reduction piece 6 and the housing 2 and the plurality of noise reduction holes 61 on the circumferential wall of the noise reduction piece 6 form a plurality of helmholtz resonance cavities, so that resonance noise reduction of noise generated by the pump body 1 can be realized, low-frequency and medium-frequency noise can be reduced, and the noise quality of the pump assembly 100 can be improved.
In some alternative embodiments of the present invention, as shown in fig. 4, a plurality of noise reduction holes 61 are arranged in a matrix on the peripheral wall of the noise reduction member 6. Therefore, the resonance silencing effect of the plurality of helmholtz resonance cavities on the noise generated by the pump body 1 can be further improved, the low and medium frequency band noise can be reduced, and the noise quality of the pump assembly 100 can be further improved.
Alternatively, as shown in FIG. 4, the noise reduction holes 61 may have a hole diameter in the range of 2-4 mm. Therefore, the noise in the middle and low frequency bands (e.g., the noise in the 630HZ band) can be significantly reduced, and it should be noted that the noise in the 630HZ band makes a human body sound harsh and sharp, thereby improving the noise quality of the pump assembly 100. For example, the aperture of the noise reduction holes 61 may be 2mm, 3mm, or 4 mm.
In some alternative embodiments of the present invention, as shown in FIG. 4, the pitch between two adjacent noise reduction holes 61 is in the range of 20-25 mm. Therefore, the mid-low frequency band noise (e.g., 630HZ frequency band noise) can be significantly reduced, thereby improving the noise quality of the pump assembly 100. For example, the pitch between two adjacent noise reduction holes 61 is 20mm, 21mm, 22mm, 23mm, 24mm or 25 mm.
It is understood that, regarding the aperture size and the pitch (the distance between two adjacent noise reduction holes 61) of the noise reduction holes 61 on the noise reduction member 6, the aperture size of the noise reduction holes 61 may be the same or different, and the pitch of the noise reduction holes 61 may be the same or different, and the present invention is not limited thereto, and the specific values thereof may be set according to the vibration of the pump body 1 and the frequency of the noise.
In some embodiments of the present invention, the plurality of noise reduction holes 61 have different hole sizes and/or different hole pitches, so that noises with different frequencies can be absorbed, thereby effectively reducing noises with different frequency bands, and further improving the sound quality of the noises of the pump assembly 100.
Optionally, the peripheral wall thickness of the noise reducer 6 is in the range of 2-4 mm. Therefore, the mid-low frequency band noise (e.g., 630HZ frequency band noise) can be significantly reduced, thereby improving the noise quality of the pump assembly 100. For example, the peripheral wall thickness of the noise damper 6 is 2mm, 3mm or 4 mm.
For example, a single vibration and noise test can be performed on the pump body 1, the vibration amplitude and the noise spectrum distribution of the pump body 1 in the circumferential direction and the axial direction are determined, then the distribution of the plurality of noise reduction holes 61 is reasonably set according to the noise spectrum distribution and the space limitation of the pump body 1, and the aperture size, the pitch of the holes and the thickness of the peripheral wall of the noise reduction piece 6 of the plurality of noise reduction holes 61 are designed, so that the noise reduction piece 6 can reduce the transmission of noise to the maximum extent.
In some alternative embodiments of the invention, the radial spacing between the noise reduction element 6 and the housing 2 is in the range 8-15 mm. Therefore, the mid-low frequency band noise (e.g., 630HZ frequency band noise) can be significantly reduced, thereby improving the noise quality of the pump assembly 100. For example, the radial spacing between the noise reduction 6 and the housing 2 is 8mm, 10mm, 12mm, 14mm or 15 mm.
For example, in a specific example of the present invention, the noise frequency of the pump body 1 is about 630Hz, the aperture range of the noise reduction holes 61 is 2-4mm, the distance range of two adjacent noise reduction holes 61 is 20-25mm, the thickness range of the peripheral wall of the noise reduction piece 6 is 2-4mm, and the radial distance range between the noise reduction piece 6 and the housing 2 is 8-15mm, so that the noise in the frequency band of about 630Hz can be significantly reduced, and the noise quality of the pump assembly 100 can be improved.
optionally, a porous sound absorbing member is provided within the resonant cavity. Therefore, the sound absorption effect of the resonant cavity is improved, and the noise reduction effect of the pump assembly 100 is further improved. For example, the porous sound absorbing member may be a mineral wool sound absorbing member, a wood sound absorbing member, or a fiber perforated sound absorbing member.
In some alternative embodiments of the invention, the bottom cover of the noise reducer 6 is provided with a cover plate 7, the cover plate 7 constituting the bottom wall of the housing 2. Thereby, the structure is simple, and the installation and connection between the housing 2 and the cover plate 7 are facilitated. For example, as shown in fig. 1 and 4, the housing 2 is formed in a hollow cylindrical body, a plurality of mounting holes 71 are formed in the circumferential direction of the cover plate 7, and a connection fastener is connected to the bottom end of the housing 2 through the mounting holes 71.
