Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and in particular to a damped low-vibration submersible pump. Background Technology

[0002] Submersible pumps are primarily used for liquid transportation, such as deep well water extraction and water supply for high-rise buildings. A submersible pump mainly consists of an electrical control unit, a motor assembly, and a pump body assembly. The electrical control unit supplies power to the motor assembly, which generates torque to drive the impeller of the pump body assembly to rotate. This draws water into the volute of the pump body assembly through the inlet, and then discharges the water from the volute through the outlet via a specific path, thus completing the liquid transportation process.

[0003] Existing submersible pumps generate significant vibrations during operation, accompanied by considerable noise, which fails to meet users' requirements for silent pumps. Utility Model Content

[0009] The shock-absorbing base includes a plurality of second damping shock absorbers evenly distributed along the circumference. The second damping shock absorbers are arranged obliquely and their two ends are respectively connected to the volute and the bottom cover.

[0010] Optionally, one end of the first damping shock absorber is fixedly connected to the side wall of the cover, and the other end of the first damping shock absorber is hinged to the stator housing with the hinge axis arranged horizontally.

[0011] Optionally, the two ends of the second damping shock absorber are respectively hinged to the vortex shell and the bottom cover, and the hinge axes are both arranged horizontally.

[0012] Optionally, the side wall of the cover is provided with a water inlet, and the bottom of the vortex shell is open to form a water inlet. The side wall of the cover is also provided with a drain outlet, and the drain outlet is connected to the vortex shell through a connecting channel.

[0013] Optionally, the water inlet is equipped with a filter screen.

[0014] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0015] The damped low-vibration submersible pump provided by this utility model has internal components such as the electrical control assembly, motor assembly, and pump body assembly suspended inside the casing by suspension springs and connected to the casing by shock-absorbing side seats and shock-absorbing bases. The suspension springs, shock-absorbing side seats, and shock-absorbing bases work together to absorb some of the vibration energy of the internal components during operation, thereby reducing the noise generated by the vibration of the internal components during operation, and thus meeting the user's requirements for a silent water pump.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0024] The following is combined Figure 1 The specific embodiments of this utility model will be described in detail below.

[0025] This embodiment provides a damped low-vibration submersible pump, including a housing 10, a bottom cover 20, an electrical control assembly 30, a motor assembly 40, a pump body assembly 50, a suspension spring 60, a shock-absorbing side seat 70, and a shock-absorbing base 80.

[0026] The cover 10 is an inverted barrel shape, meaning it is sealed at the top and open at the bottom.

[0027] The bottom cover 20 is connected to the bottom end of the cover 10.

[0028] Specifically, the bottom end of the cover 10 has a connecting flange extending outward, and the bottom cover 20 is fixedly connected to the connecting flange by bolts. Of course, the bottom cover 20 can also be fixedly connected to the cover 10 by clips or other means.

[0029] It should be noted that, for ease of disassembly and maintenance, the cover 10 and the bottom cover 20 are preferably connected in a detachable manner.

[0030] During installation, the bottom cover 20 is simply fixed to the surface to be installed. For example, in this embodiment, the bottom cover 20 is fixed to the ground 90 by ground bolts 21, and a rubber gasket 22 is added between the bottom cover 20 and the ground 90 to achieve a seal between the bottom cover 20 and the ground 90.

[0031] The electrical control component 30, the motor component 40, and the pump body component 50 are all located inside the cover 10 and arranged sequentially from top to bottom.

[0032] It is easy to understand that the electronic control assembly 30, the motor assembly 40, and the pump body assembly 50 are all internal components and belong to structures known in the art: the electronic control assembly 30 is mainly used to power the motor assembly 40, and the electronic control assembly 30 includes a top cover 31, an electronic control housing, and electrical components located in the cavity enclosed by the electronic control housing and the top cover 31; the motor assembly 40 is mainly used to generate torque to provide power to the pump body assembly 50, and the motor assembly 40 mainly includes a stator and a rotor, and the stator includes a stator housing 41, a stator core, etc.; the pump body assembly 50 is mainly used to generate centrifugal force to transport liquid using the torque of the motor assembly 40, and the pump body assembly 50 includes an impeller and a volute 51.

[0033] The suspension spring 60 is arranged vertically and its two ends are respectively connected to the top wall of the cover 10 and the top cover 31.

[0034] Specifically, the suspension spring 60 uses a high-strength damping spring.

[0035] Specifically, hooks can be installed on both the top wall and the top cover 31 of the cover 10 to connect the suspension spring 60.

[0036] The damping side seat 70 includes a plurality of first damping dampers 71 evenly distributed along the circumference. The first damping dampers 71 are arranged laterally and their two ends are respectively connected to the side wall of the cover 10 and the stator housing 41.

[0037] Specifically, the number of first damping shock absorbers 71 is not limited. For example, in this embodiment, three first damping shock absorbers are evenly distributed along the circumference, while in other embodiments, four or more can be designed.

[0038] Specifically, the type of the first damping shock absorber 71 is not limited. For example, in this embodiment, the first damping shock absorber 71 is a hydraulic damping shock absorber. In other embodiments, a pneumatic damping shock absorber or a spring damping shock absorber may also be used.

[0039] Specifically, one end of the first damping shock absorber 71 is fixedly connected to the side wall of the cover 10, and the other end of the first damping shock absorber 71 is hinged to the stator housing 41 with the hinge axis arranged horizontally.

[0040] More specifically, a hinge seat is fixed to the outside of the stator housing 41, and the other end of the first damping shock absorber 71 is connected to the hinge seat to achieve hinge.

[0041] The damping base 80 includes a plurality of second damping dampers 81 evenly distributed along the circumference. The second damping dampers 81 are arranged obliquely and their two ends are respectively connected to the volute 51 and the bottom cover 20.

[0042] Specifically, the number of second damping shock absorbers 81 is not limited. For example, in this embodiment, three second damping shock absorbers are evenly distributed along the circumference, while in other embodiments, four or more can also be designed.

[0043] Specifically, the type of the second damping shock absorber 81 is not limited. For example, in this embodiment, the second damping shock absorber 81 is a hydraulic damping shock absorber. In other embodiments, a pneumatic damping shock absorber or a spring damping shock absorber may also be used.

[0044] Specifically, the two ends of the second damping shock absorber 81 are hinged to the vortex shell 51 and the bottom cover 20 respectively, and the hinge axes are both arranged horizontally.

[0045] More specifically, hinge seats are fixed on the outer side of the vortex shell 51 and the bottom cover 20, and the two ends of the second damping shock absorber 81 are connected to the corresponding hinge seats to achieve hinge.

[0046] In addition, the side wall of the cover 10 is provided with a water inlet 11, and the bottom of the vortex shell 51 is open to form a water inlet 52. The side wall of the cover 10 is also provided with a drain outlet 12, and the drain outlet 12 is connected to the vortex shell 51 through a connecting channel.

[0047] Furthermore, the water inlet 11 is equipped with a filter screen 13.

[0048] The working principle of the damped low-vibration submersible pump in this embodiment is as follows:

[0049] During operation, the bottom cover 20 is fixed to the target position on the ground 90 using ground bolts 21 and rubber pads 22 to complete the installation of the submersible pump; external water enters the housing 10 through the inlet 11 and is filtered out by the filter screen 13; the electrical control component 30 supplies power to the motor component 40, the motor component 40 starts and drives the impeller of the pump body component 50 to rotate, generating centrifugal force; the water in the housing 10 is drawn into the volute 51 from the inlet 52 under the action of centrifugal force, and reaches the drain outlet 12 along the connecting channel under the action of centrifugal force, and is then thrown out from the drain outlet 12.

[0050] During operation, some of the vibration energy generated by the internal components such as the electrical control component 30, motor component 40, and pump body component 50 is absorbed by the suspension spring 60, shock-absorbing side seat 70, and shock-absorbing base 80, thereby reducing the noise generated by the internal components due to vibration during operation and thus meeting the user's requirements for a silent water pump.

[0051] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
