Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and more specifically, to a centrifugal pump shock-absorbing base. Background Technology

[0002] Centrifugal pumps operate by using the centrifugal motion of water caused by the rotation of an impeller. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, causing the pump shaft to drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion, being thrown towards the outer edge of the impeller and flowing into the pump's discharge pipe through the flow channel of the volute casing. At the same time, the base serves as a supporting and fixing component for the centrifugal pump, protecting it and ensuring its long-term stable operation.

[0003] The existing public technology application number is CN202420300737.4, which describes a centrifugal pump with a shock-absorbing base. When the centrifugal pump with the shock-absorbing base is in use, the rubber pad is embedded in the base and the connection end is fastened with screws. At the same time, the rubber pad, as a shock-absorbing material, is completely embedded in the hole groove of the base to seal the hole groove of the base. The rubber pad is connected to the factory ground to achieve the needs of shock absorption and noise reduction.

[0004] However, the above-mentioned patent still has certain drawbacks in use: the rubber pads used for shock absorption are embedded in the base hole groove by screws. Although they can block the vibration path, the entire structure needs to be disassembled when replacing or maintaining them. Parts with minor damage are easy to be wasted, which increases maintenance costs. Moreover, the screw holes on both sides of the I-shaped groove need to match the size of the fixed support. If the specifications of the pump body support are different, customized adjustments are required. The flexibility of adaptation is insufficient, which reduces the versatility and practicality of the structure. The overall use effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a centrifugal pump vibration damping base, which has the advantages of convenient maintenance, strong versatility, and modular vibration damping, thereby solving the problems mentioned in the background technology.

[0008] (II) Technical Solution

[0009] To achieve the aforementioned advantages of convenient maintenance, strong versatility, and modular shock absorption, the specific technical solution adopted by this utility model is as follows:

[0010] A centrifugal pump vibration damping base includes a base and a damping block. The base has four sets of plates. The four sets of bases are symmetrically and slidably connected in the transverse direction between each pair of bases, and symmetrically and slidably connected in the longitudinal direction between each pair of bases. Several sets of fastening holes are provided on the surface of the transverse plates, the surface of the longitudinal plates, and the surface of the base, and the fastening holes are connected by fastening bolts.

[0011] Furthermore, several sets of shock-absorbing blocks are threadedly connected to the bottom surface of the base. Each shock-absorbing block consists of a polygonal plate, a connector, and a rubber pad. The bottom of the polygonal plate is adhered with a rubber pad, and a connector is welded to the middle of the top of the polygonal plate.

[0012] Furthermore, a bearing plate is welded to the bottom of the inner surface of the base, and an array of screw holes is provided on the surface of the bearing plate.

[0013] Furthermore, several sets of receiving grooves are provided on the inner surface of the base.

[0014] Furthermore, anti-detachment tabs are provided at one end of the transverse plate and one end of the longitudinal plate.

[0015] Furthermore, the base has several sets of threaded holes at its bottom.

[0016] Furthermore, the connector surface is provided with threads.

[0017] Furthermore, a threaded plate is welded to the outer surface of the base.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a centrifugal pump vibration damping base, which has the following beneficial effects:

[0020] (1) By adopting horizontal and vertical plates, the present invention allows personnel to extend and retract the horizontal and vertical plates according to the different sizes of the centrifugal pumps to be connected, thereby changing the spacing between multiple sets of base seats, which in turn changes the spacing between multiple sets of bearing plates. After all adjustments are completed, the centrifugal pump can be placed directly on the bearing plate. At this time, the centrifugal pump can be threadedly connected to the support legs of the centrifugal pump through the screw hole array on the bearing plate, thereby improving the practicality and versatility of the structure, making it easier to use, and having the advantage of strong versatility.

[0021] (2) This utility model adopts shock-absorbing blocks and connectors. Since the base is equipped with shock-absorbing blocks, the vibration can be weakened to a certain extent by the rubber pads at the bottom of the shock-absorbing blocks, thereby achieving the purpose of shock absorption. Since the shock-absorbing blocks are modularly set and each shock-absorbing block is independently set and connected to the base through connectors, when damage occurs, only the corresponding shock-absorbing block needs to be rotated and removed, without involving other intact shock-absorbing blocks, thereby avoiding unnecessary waste and reducing losses. At the same time, the corresponding replacement can also improve the overall maintenance efficiency. Compared with the overall multiple bolt connections, it can effectively reduce maintenance time and facilitate better use. It has the advantages of convenient maintenance and modular shock absorption. Attached Figure Description

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a centrifugal pump shock-absorbing base is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a centrifugal pump vibration damping base according to an embodiment of the present utility model includes a base 1 and a damping block 2. The base 1 is provided with four sets. Several sets of transverse plates 3 are symmetrically slidably connected between each pair of the four sets of base 1 in the transverse direction, and several sets of longitudinal plates 6 are symmetrically slidably connected between each pair of the base 1 in the longitudinal direction. Several sets of fastening holes 4 are opened on the surface of the transverse plates 3, the surface of the longitudinal plates 6, and the surface of the base 1, and the fastening holes 4 are connected to each other by fastening bolts 5.

[0032] In one embodiment, a number of damping blocks 2 are threadedly connected to the bottom surface of the base 1. The damping block 2 consists of a polygonal plate 10, a connector 11, and a rubber pad 9. The bottom of the polygonal plate 10 is adhered with the rubber pad 9, and the connector 11 is welded to the middle of the top of the polygonal plate 10. The polygonal plate 10 is made of metal to ensure strength. The rubber material in the rubber pad 9 has high elasticity and flexibility. When external vibration or impact force acts on the rubber pad 9, the rubber molecular chain undergoes reversible deformation, converting mechanical energy into elastic potential energy for storage. During the deformation recovery process, the rubber generates heat energy due to internal friction (energy dissipation), further consuming vibration energy. Since the rubber pad 9 is frequently used for vibration damping in daily life, it will not be described in detail. For example, the existing patent application number is: CN202420300737.4; the rubber bushing in the automobile suspension system absorbs road bump energy through deformation.

[0033] In one embodiment, a bearing plate 7 is welded to the bottom of the inner surface of the base 1, and a screw hole array 8 is provided on the surface of the bearing plate 7. The screw hole array is set to adapt to the position of the screw holes on the surface of pump legs of different sizes, thereby realizing the fixed operation of the centrifugal pump and facilitating subsequent use.

[0034] In one embodiment, a number of receiving grooves 13 are provided on the inner surface of the base 1. The receiving grooves 13 are provided to facilitate the adjustment of the transverse plate 3 and the longitudinal plate 6.

[0035] In one embodiment, anti-detachment plates 12 are provided at one end of the transverse plate 3 and one end of the longitudinal plate 6. The anti-detachment plates 12 are provided to limit the maximum movable range of the transverse plate 3 and the longitudinal plate 6, preventing them from moving out of the base 1 and ensuring the structural performance. At the same time, the transverse plate 3 and the longitudinal plate 6 can be fixed at one end and moved at the other end or both ends can be moved to achieve relative adjustment of the base 1, thereby adapting to the accommodation of centrifugal pumps of different sizes and the subsequent fixing operation of the pump body legs, expanding the applicability of the device and improving the overall performance.

[0036] In one embodiment, the base 1 has several sets of threaded holes at its bottom. The threaded holes are provided to facilitate the connection and fastening of the connecting rod.

[0037] In one embodiment, the connector 11 has threads on its surface. The threads are designed to facilitate connection with the threaded hole at the bottom of the base 1, thereby enabling the connection of the shock absorber and facilitating subsequent use.

[0038] In one embodiment, a threaded plate is welded to the outer surface of the base 1, and a threaded hole is provided on the top of the threaded plate to facilitate the connection of the entire base to the external structure by fasteners such as bolts, thereby facilitating the subsequent fixing operation of the centrifugal pump.

[0039] Working Principle: In actual use, personnel can extend and retract the transverse plate 3 and longitudinal plate 6 according to the different sizes of the centrifugal pumps to be connected, thereby changing the spacing between multiple sets of base seats 1, which in turn changes the spacing between multiple sets of bearing plates 7. After all adjustments are completed, personnel can place the centrifugal pump directly onto the bearing plate 7. At this time, the centrifugal pump's legs can be threadedly connected through the screw hole array 8 on the bearing plate 7, thereby improving the practicality and versatility of the structure and facilitating better use. Then, the entire base can be connected to the ground through bolts and the threaded plates on the surface of the base seat 1, thereby achieving the structural fixation operation. Due to the foundation... The base 1 is equipped with a shock-absorbing block 2 at the bottom. The vibration can be weakened to a certain extent by the rubber pad 9 at the bottom of the shock-absorbing block 2, thereby achieving the purpose of shock absorption. Since the shock-absorbing block 2 adopts a modular design and each shock-absorbing block 2 is independently set and connected to the base 1 through the connector 11, when damage occurs, only the corresponding shock-absorbing block 2 needs to be rotated and removed without affecting other intact shock-absorbing blocks 2, thus avoiding unnecessary waste and reducing wear. At the same time, the corresponding replacement can also improve the overall maintenance efficiency. Compared with multiple bolt connections, it can effectively reduce maintenance time and facilitate better use. The device as a whole has the advantages of convenient maintenance, strong versatility, and modular shock absorption.
