Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vibration damping structures, and in particular to a connecting bracket, pump assembly, and refrigeration system. Background Technology
[0002] As one of the key pieces of equipment in ship cooling systems, marine cooling water pumps are widely used in the main and auxiliary engine cooling systems of various ships. Their operational stability and reliability directly affect the safe operation of ship propulsion systems.
[0003] Because cooling water pumps operate continuously in complex environments, they must withstand vibrations and impacts caused by waves, wind, and the propulsion system during ship navigation, as well as maintain stable operation under dynamic conditions such as ship tilting and rolling. Therefore, higher requirements are placed on the structural strength, impact resistance, and vibration and noise control of cooling water pumps.
[0004] Traditional equipment vibration and noise reduction methods commonly employ spring dampers, rubber damping pads, or hydraulic dampers to reduce the transmission of vibrations generated during equipment operation. However, these traditional methods have low natural frequencies and cannot meet the equipment's requirements for resistance to impact, tilting, and swaying in harsh environments, severely impacting the equipment's reliability.

[0115] refer to Figures 1 to 15 Some embodiments of this disclosure provide a connecting bracket, including a bracket body and a reinforcing member formed on one side of the bracket body. The reinforcing member includes a first rib group 204 and a first mounting base 201. The bracket body includes a second mounting base 202, a third mounting base 205, and a second rib group 203. The first mounting base 201 is connected to the second mounting base 202 via the first rib group 204. The second mounting base 202 and the third mounting base 205 are connected via the second rib group 203. The first mounting base 201, the second mounting base 202, and the third mounting base 205 are configured to be connected to different components, respectively.
[0116] Optionally, refer to Figure 2 The reinforcing body and the support body are arranged in layers along the height direction of the support body. Correspondingly, the first mounting base 201, the first rib group 204, the second mounting base 202, the second rib group 203 and the third mounting base 205 are connected in sequence along the height direction of the support body.
[0117] In the connecting bracket 20, the device or component connected to one or more of the components of the first mounting base 201, the second mounting base 202, and the third mounting base 205 can be a device or component that generates vibration, for example, referring to... Figure 1 The connecting bracket 20 can serve as a connecting bracket for mounting the pump 30 on the base. The drive device 10 of the pump 30 is mounted on the first mounting base 201, the pump 30 is mounted on the third mounting base 205, and the connecting bracket 20 is mounted on the base via the second mounting base 202.
[0118] Optionally, refer to Figure 2 and Figure 3 The first mounting base 201 is provided with a first connecting hole 2011, and the drive device 10 can be mounted on the first mounting base 201 via a threaded connector and the first connecting hole 2011. Optionally, refer to Figure 4 The third mounting base 205 is provided with a second connecting hole 2051, and the pump 30 can be installed on the third mounting base 205 through a threaded connector and the second connecting hole 2051.
[0119] In the connecting bracket 20 provided in the embodiments of this disclosure, the bracket body and the reinforcing body form a double-layer bracket structure. The first rib group 204 is composed of multiple ribs. The multiple ribs in the first rib group 204 connected to the second mounting seat 202 can not only play a structural constraint role on the bracket body and improve the load-bearing capacity of the connecting bracket 20, but also serve as a vibration damping structure to prevent the transmission of vibration waves between the bracket body and the first mounting seat 201. Furthermore, the second mounting seat 202 and the third mounting seat 205 in the main bracket body are also connected by the second rib group 203 composed of multiple ribs, which can further prevent the transmission of vibration waves between the second mounting seat 202 and the third mounting seat 205, thereby effectively preventing the vibration from being transmitted between the first mounting seat 201, the second mounting seat 202 and the third mounting seat 205 and suppressing the accumulation of vibration energy.
[0120] Because the connecting bracket 20 provided in the embodiments of this disclosure can improve the rigidity of the connecting bracket, the connecting bracket 20 is not prone to large deformation, reducing the risk of secondary vibration caused by local structural deformation, and increasing the natural frequency of the connecting bracket 20, which is beneficial for the connecting bracket 20 to better resist low-frequency vibration.
[0121] When the connecting bracket 20 is used as a fixed support for the cooling water pump, it enables the pump to have stronger resistance to deformation under vibration excitation, thereby improving the overall structural stability. It can also cope with vibration excitation from components mounted on different mounting bases, achieving comprehensive vibration reduction control of the cooling water pump in multi-degree-of-freedom vibration environments and improving the problem of large low-frequency vibration in the cooling water pump. By reducing the vibration and noise levels during the operation of the cooling water pump, fatigue damage caused by vibration can also be reduced, extending the service life of the equipment.
[0122] In some embodiments of the connecting bracket, the bracket body and the reinforcing body are integrally formed, and / or the first rib group 204 and the first mounting base 201 are integrally disposed, and / or the second mounting base 202, the third mounting base 205 and the second rib group 203 are integrally disposed.
[0123] Optionally, refer to Figures 2 to 10 The first mounting base 201, the first rib group 204, the second mounting base 202, the third mounting base 205, and the second rib group 203 are all integrally formed. The various parts of the connecting bracket can be integrally formed, for example, by casting.
[0124] The arrangement of the connecting bracket in this embodiment has at least one of the following advantages: improving the structural continuity between the bracket body and the reinforcing body; improving the structural continuity of each part of the reinforcing body; and improving the structural continuity of each part of the bracket body. Therefore, the connecting bracket 20 in this embodiment has stronger overall deformation resistance and greater stiffness, which helps it better resist low-frequency vibrations.
[0125] In some embodiments of the connecting bracket, the first rib group 204 includes a first annular rib 2045 and a plurality of first extended ribs, the plurality of first extended ribs extending between the outer edges of the first annular rib 2045 and the second mounting base 202, and at least two of the first extended ribs extending in different directions.
[0126] In some embodiments of the connecting bracket, the second rib group 203 includes a second annular rib 2033 and a plurality of second extended ribs, the plurality of second extended ribs extending between the second annular rib 2033 and the outer edge of the second mounting base 202, and at least two of the second extended ribs extending in different directions.
[0127] Optionally, a through cavity is formed inside the first annular rib 2045 and the second annular rib 2033 so that the drive shaft of the drive device 10 of the pump 30 can pass through the cavity and drive the pump 30.
[0128] In this embodiment, the first rib group 204 and the second rib group 203 can cope with vibration excitation from different directions. Specifically, the first annular rib 2045 and the second annular rib 2033 can prevent vibration waves from propagating from the center region to the edge region or from the edge region to the center region of the connecting bracket 20. The first extended rib and the second extended rib can prevent vibration waves from propagating circumferentially along the connecting bracket 20. Furthermore, when vibration waves propagate between the first mounting base 201 and the second mounting base 202, or between the second mounting base 202 and the third mounting base 205, they can also be attenuated by the first rib group 204 and the second rib group 203.
[0129] Furthermore, the first and second extension ribs with different extension directions can form non-parallel vibration damping structures in areas other than the corresponding annular ribs. For vibration waves that pass perpendicularly through one of the first or second extension ribs, when they are transmitted to the other first or second extension rib with a different extension direction, they will enter the other first or second extension rib with a different extension direction at an angle, extending the path through the vibration damping structure and thus further improving the vibration damping effect.
[0130] In some embodiments of the connecting bracket, a plurality of first extending ribs are arranged divergingly, and / or a plurality of second extending ribs are arranged divergingly.
[0131] Optionally, a plurality of first extending ribs are arranged radially. Optionally, a plurality of second extending ribs are arranged radially.
[0132] In this embodiment, multiple first extending ribs are distributed divergently, ensuring that the rib setting area fully covers the region between the outer edges of the first annular rib 2045 and the second mounting base 202. Similarly, multiple second extending ribs are distributed divergently in the region between the outer edges of the first annular rib 2045 and the second mounting base 202, ensuring that the rib setting area fully covers the region between the outer edges of the second annular rib 2033 and the second mounting base 202. Therefore, the rib setting method in this embodiment can make the stiffness distribution of the connecting bracket 20 more uniform, reduce weak stiffness areas, and also make the damping distribution of the connecting bracket 20 more uniform, achieving a good vibration damping effect.
[0133] In some embodiments of the connecting bracket, a plurality of first extending ribs extend in a straight line.
[0134] In this embodiment, multiple first extension ribs extend along a straight line and at least two of the first extension ribs extend in different directions. The angle between the first extension ribs with different extension directions is fixed, which is beneficial for the vibration wave to enter the other first extension rib with a different extension direction at an angle.
[0135] refer to Figures 5 to 7 In some embodiments of the connecting bracket, the corner of the second mounting base 202 is provided with a connecting structure 206, the first rib group 204 includes corner ribs 2041, each corner of the second mounting base 202 is provided with at least one corner rib 2041, and each corner rib 2041 surrounds the side of the connecting structure 206 near the interior of the second mounting base 202.
[0136] Optionally, the connecting bracket 20 is a mounting bracket for the pump 30, and the connecting structure 206 is a mounting foot for the pump 30.
[0137] Optionally, each corner of the second mounting base 202 is provided with a plurality of corner ribs 2041 at intervals. The plurality of corner ribs 2041 are arranged at intervals along the diagonal direction of the second mounting base 202, and both ends of each corner rib 2041 extend to the outer contour of the second mounting base 202. Optionally, refer to Figure 6 Each corner of the second mounting base 202 is provided with two corner ribs 2041 at intervals, and the widths of the two corner ribs 2041 are a4 and a5 respectively, and a4=a5.
[0138] In this embodiment, the corner rib 2041 can increase the rigidity of the location of the connecting structure 206 and prevent vibration waves from being transmitted to the corner of the connecting bracket 20.
[0139] refer to Figures 5 to 7, in the connecting bracket of some embodiments, the plurality of first extending ribs include vertical ribs 2043, transverse ribs 2046 and oblique ribs 2044. The vertical ribs 2043 extend along the first direction y of the second mounting base 202. The transverse ribs 2046 extend along the second direction x of the second mounting base 202, wherein the second direction x is perpendicular to the first direction y. The oblique ribs 2044 are arranged at an included angle with both the transverse ribs 2046 and the vertical ribs 2043, and at least one oblique rib 2044 is arranged between adjacent transverse ribs 2046 and vertical ribs 2043.
[0140] Reference Figure 6 , the included angle c2 between adjacent transverse ribs 2046 and vertical ribs 2043 is 90°. Optionally, on a cross section perpendicular to the third direction z, the two transverse ribs 2046 respectively extend along the radial direction of the first annular rib 2045, the two vertical ribs 2043 respectively extend along the radial direction of the first annular rib 2045, the oblique ribs 2044 on both sides of each transverse rib 2046 in the first direction y are symmetrically arranged about the center line of the corresponding transverse rib 2046 in the second direction x, and the oblique ribs 2044 on both sides of each vertical rib 2043 in the second direction x are symmetrically arranged about the center line of the corresponding vertical rib 2043 in the first direction y, wherein the third direction z is perpendicular to both the first direction y and the second direction x.
[0141] In this embodiment, the vertical ribs 2043 and the transverse ribs 2046 can respectively increase the stiffness of the connecting bracket 20 along the first direction y and the second direction x, while the oblique ribs 2044 can increase the stiffness of the area of the connecting bracket 20 between the vertical ribs 2043 and adjacent transverse ribs 2046. The vertical ribs 2043, transverse ribs 2046 and oblique ribs 2044 form a radial "米"-shaped composite vibration damping structure. Based on such a composite vibration damping structure, the ability of the connecting bracket 20 to cope with vibration excitation from different directions can be improved.
[0142] In the connecting bracket of some embodiments, the oblique ribs 2044 extend from the first annular rib 2045 toward the corners of the second mounting base 202, and intersect with at least one corner rib 2041.
[0143] Optionally, reference Figures 5 to 7 , a plurality of corner ribs 2041 are arranged at each corner of the second mounting base 202, and the oblique ribs 2044 intersect with all the plurality of corner ribs 2041 arranged at each corner of the second mounting base 202.
[0144] In this embodiment, one end of the inclined rib 2044 is connected to the first annular rib 2045, and the other end is connected to at least one corner rib 2041. The vibration damping range spans the center and corners of the connecting bracket 20, thus further improving the vibration damping effect.
[0145] In some embodiments of the connecting bracket, the corner ribs 2041 are arc-shaped.
[0146] Optionally, refer to Figures 5 to 7 The corner rib 2041 is rounded. Optionally, refer to... Figures 5 to 7 The corner ribs 2041 are set to protrude towards the inside of the connecting bracket 20.
[0147] In this embodiment, the arc-shaped corner rib 2041 can block both vibration waves from the internal region of the connecting bracket 20 and vibration waves transmitted along the circumference of the connecting bracket. During the transmission to the corner of the connecting bracket 20, vibration waves from different directions can be effectively attenuated.
[0148] refer to Figures 5 to 6 In some embodiments of the connecting bracket, the first rib group 204 satisfies at least one of the following dimensional and / or angular relationships.
[0149] V1*1 / 5≤R1≤V1*1 / 2, where R1 represents the inner radius of the first annular rib 2045, and V1 represents the dimension of the second mounting base 202 along the first direction y.
[0150] Within this size range, the first annular rib 2045 can adequately cover the central area of the connecting bracket 20, thus providing significant vibration damping. Optionally, refer to... Figure 6 The dimension V1 of the second mounting base 202 along the first direction y is greater than the dimension V2 of the second mounting base 202 along the second direction x. Correspondingly, the length b1 of the vertical rib 2043 is greater than the length b2 of the horizontal rib 2046.
[0151] a6≤h1, where a6 represents the width of the first annular rib 2045 and h1 represents the height of the first rib group 204.
[0152] h1≤30mm, where h1 represents the height of the first stiffener group 204.
[0153] When the weight of the connecting bracket 20 is constant, the larger h1 is, the better the vibration damping effect of the first rib group 204. Therefore, under the premise of ensuring the weight of the connecting bracket 20, h1 should be as large as possible so that the first rib group 204 can better block the transmission of vibration waves. In some embodiments, the vibration isolation effect is best when h1 = 30mm.
[0154] When a6=h1, the width and height of the first annular rib 2045 are the same.
[0155] a1=a2, where a1 represents the width of the vertical rib 2043 and a2 represents the width of the horizontal rib 2046.
[0156] 20mm≤a1≤30mm, where a1 represents the width of the vertical stiffener 2043.
[0157] 15mm≤a3≤20mm, where a3 represents the width of the diagonal rib 2044.
[0158] The second mounting base 202 has multiple corner ribs 2041 spaced apart at each corner, where b3≥2*b4, b3 represents the length of the diagonal rib 2044, and b4 represents the spacing between two adjacent corner ribs 2041.
[0159] 30°≤c1≤60°, where c1 represents the angle between the vertical stiffener 2043 and the diagonal stiffener 2044.
[0160] 30°≤c3≤60°, where c3 represents the angle between the transverse stiffener 2046 and the diagonal stiffener 2044.
[0161] for Figure 5 and Figure 6 With the setting method, when c1=30° and c3=60°, or when c1=60° and c3=30°, the radial composite vibration damping structure formed by the vertical stiffener 2043, the horizontal stiffener 2046 and the diagonal stiffener 2044 achieves the best vibration damping effect.
[0162] a4 = a3, where a4 represents the width of the corner rib 2041 and a3 represents the width of the diagonal rib 2044.
[0163] The consistent width of the corner ribs 2041 and the diagonal ribs 2044 facilitates the consistency of the stiffness enhancement effect of the connecting bracket 20 at different positions, and maintains the consistency of the vibration isolation effect of the first rib group 204 in different directions.
[0164] The dimensional and / or angular relationships adopted in this embodiment can further improve the vibration reduction effect of the connecting bracket 20.
[0165] refer to Figure 7 In some embodiments of the connecting bracket, the first rib group 204 includes a first connecting rib 2048 and / or a second connecting rib 2049. The two ends of the first connecting rib 2048 are respectively connected to two corner ribs 2041 and intersect with a vertical rib 2043. The two ends of the second connecting rib 2049 are respectively connected to two corner ribs 2041 and intersect with a horizontal rib 2046.
[0166] Optionally, refer to Figure 7 At least one first connecting rib 2048, for example, a single first connecting rib 2048, is connected between two adjacent corners of the second mounting base 202 along the first direction y. Optionally, at least one second connecting rib 2049 is connected between two adjacent corners of the second mounting base 202 along the second direction x, for example, referring to... Figure 7 Two second connecting ribs 2049 are arranged at intervals along the first direction y.
[0167] In this embodiment, by setting the first connecting rib 2048 and / or the second connecting rib 2049, the stiffness of the edge positions of the connecting bracket 20 along the second direction x and the first direction y can be further increased, and the vibration damping effect at the location can be improved.
[0168] In some embodiments, reference Figure 7 The first connecting rib 2048 is arc-shaped. In some embodiments, reference... Figure 7 The second connecting rib 2049 is arc-shaped.
[0169] Optionally, refer to Figure 7 The first connecting rib 2048 is arc-shaped, and the second connecting rib 2049 is arc-shaped. Optionally, refer to... Figure 7 The first connecting rib 2048 protrudes inward toward the connecting bracket 20, and the second connecting rib 2049 protrudes inward toward the connecting bracket 20. The two ends of the first connecting rib 2048 are respectively connected to the ends of the two corner ribs 2041.
[0170] In this embodiment, the arc-shaped first connecting rib 2048 and the arc-shaped second connecting rib 2049 can both block vibration waves from the internal region of the connecting bracket 20 and vibration waves transmitted along the circumference of the connecting bracket. During the transmission to the edge of the connecting bracket 20, vibration waves from different directions can be effectively attenuated.
[0171] refer to Figure 7 In some embodiments of the connecting bracket, the first rib group 204 includes a plurality of nested first annular ribs 2045.
[0172] Optionally, refer to Figure 7 One end of the oblique rib 2044 is connected to the outermost of the plurality of first annular ribs 2045.
[0173] In this embodiment, by setting multiple nested first annular ribs 2045, the resistance of the ribs to the vibration wave can be further increased when the vibration wave is transmitted between the central region and the edge region of the connecting bracket 20, thereby further improving the vibration damping effect.
[0174] refer to Figure 8 and Figure 9 In some embodiments of the connecting bracket, the second extending rib includes a first rib segment 2031 and a second rib segment 2032. The first rib segment 2031 extends from the outside of the second annular rib 2033 to the outer edge of the second mounting base 202, and the second rib segment 2032 is disposed on the outer edge of the second mounting base 202 and extends in the direction of the outer edge of the second mounting base 202.
[0175] Optionally, refer to Figure 8 and Figure 9 The second stiffener group 203 includes four second extended stiffeners, which are symmetrically distributed about a plane perpendicular to the second direction x. Optionally, refer to Figure 8 and Figure 9 The second reinforcing bar segment 2032 extends along the second direction x.
[0176] In this embodiment, the first rib segment 2031 can prevent the vibration wave from being transmitted along the circumference of the connecting bracket 20, and the second rib segment 2032 can prevent the vibration wave from being transmitted from the edge area of the connecting bracket 20 to the center area, thereby achieving the corresponding vibration damping effect.
[0177] Based on the arrangement of the second rib group 203 in this embodiment, the vibration acceleration level at the location of the connecting structure 206 can be reduced from 105dB to 99.8dB, a reduction of 5.2dB. It can be seen that the connecting bracket 20 in the above embodiment can effectively attenuate the vibration and noise at the location of the connecting structure 206.
[0178] refer to Figures 5 to 10 In some embodiments of the connecting bracket, the second rib group 203 satisfies at least one of the following dimensional and / or angular relationships.
[0179] R2 = R1, where R1 represents the inner radius of the first annular rib 2045 and R2 represents the inner radius of the second annular rib 2033.
[0180] h2 = 2 * h1, where h1 represents the height of the first stiffener group 204 and h2 represents the height of the second stiffener group 203.
[0181] Given a fixed rib width, the greater the rib height, the more significant the vibration damping effect. This design allows vibration waves to be significantly attenuated after passing through the second rib group 203.
[0182] a6 = a8, where a6 represents the width of the first annular rib 2045 and a8 represents the width of the second annular rib 2033.
[0183] The arrangement of having the same width for the first annular rib 2045 and the second annular rib 2033 helps to maintain the consistency of the effect of the first rib group 204 and the second rib group 203 in strengthening the rigidity of the connecting bracket 20, as well as the consistency of the vibration isolation effect of the first rib group 204 and the second rib group 203 in the direction from the edge to the center of the connecting bracket 20.
[0184] a3 = a7, where a3 represents the width of the first extended rib and a7 represents the width of the first rib segment 2031.
[0185] The arrangement that the width of the first extended rib is the same as the width of the first rib segment 2031 helps to maintain the consistency of the stiffness enhancement effect of the first rib group 204 and the second rib group 203, as well as the consistency of the circumferential vibration isolation effect of the first rib group 204 and the second rib group 203 in the connecting bracket 20.
[0186] The second reinforcing bar segment 2032 extends along a second direction x perpendicular to the first direction y, 30°≤c4≤60°, and / or, 120°≤c5≤150°, where c4 represents the angle between the first reinforcing bar segment 2031 and the first direction y, and c5 represents the angle between two adjacent first reinforcing bar segments 2031 along the first direction y.
[0187] The aforementioned angle range allows the effect of the second rib segment 2032 in enhancing rigidity to cover the area between the edge of the connecting bracket 20 and the second annular rib 2033 more evenly.
[0188] a12 = a7, where a7 represents the width of the first reinforcing bar segment 2031 and a12 represents the width of the second reinforcing bar segment 2032.
[0189] The arrangement that the width of the first extended rib is the same as the width of the second rib segment 2032 helps to maintain the consistency of the reinforcing stiffness of the second extended rib at different positions of the connecting bracket 20, as well as the consistency of the circumferential vibration isolation effect of the first rib group 204 and the second rib group 203 in the connecting bracket 20.
[0190] At least one of the plurality of first extending ribs has the same extending direction as the second rib segment 2032, b5=b2, where b5 represents the length of the second rib segment 2032 and b2 represents the length of the first extending rib that has the same extending direction as the second rib segment 2032.
[0191] Figure 6 In the diagram, b6 represents the length of the first reinforcing bar segment 2031. Figures 5 to 9In the embodiment shown, the first extending rib with the same extending direction as the second rib segment 2032 is the transverse rib 2046, and b2 is the length of the transverse rib 2046.
[0192] The dimensional and / or angular relationships adopted in this embodiment can further enhance the vibration damping effect of the connecting bracket 20.
[0193] Figure 11 Frequency response function curves of the connecting bracket 20 of some embodiments of this disclosure and the connecting bracket using a single layer of ribs in the related art are shown. Harmonic response analysis was used to compare the response magnitudes at the location of the connecting structure 206 of the two types of connecting brackets under the same force. The results show that, in most frequency ranges, the amplitude response of the connecting bracket 20 provided by the embodiments of this disclosure is significantly lower than that of the connecting bracket using a single layer of ribs in the related art. This indicates that, compared with the connecting brackets in the related art, the vibration wave attenuates more significantly during its transmission to the location of the connecting structure 206 in the connecting bracket 20 provided by the embodiments of this disclosure.
[0194] Figure 12 The first-order mode of the connection bracket using a single-layer rib in the relevant technology is shown through simulation calculation. Figures 13 to 15 The first three modes of the connecting bracket 20 of some embodiments of this disclosure, obtained through simulation calculations, are shown. In the connecting bracket 20, the first rib group includes the previously mentioned corner rib 2041, vertical rib 2043, diagonal rib 2044, first annular rib 2045, and transverse rib 2046; the second rib group includes the previously mentioned first rib segment 2031, second rib segment 2032, and second annular rib 2033. Figures 12 to 15 It can be seen that the first three modal frequencies of the connecting bracket are 1184.5Hz, 1662.6Hz, and 2572.4Hz, respectively. Compared with the connecting brackets in related technologies, the first modal frequency of the connecting brackets in related technologies is only 292.63Hz. The first modal frequency of the connecting bracket 20 provided in the embodiments of this disclosure is increased by about 304%. It is evident that the connecting bracket 20 provided in the embodiments of this disclosure has a higher modal frequency and higher stiffness, thus effectively improving low-frequency vibration.

The drive unit 10 is configured to drive the pump 30. The pump 30 and the drive unit 10 are connected via the connecting bracket 20.
[0196] The pump assembly provided in the embodiments of this disclosure has the advantages of the connecting bracket 20 provided in the embodiments of this disclosure.
[0197] In some embodiments of the pump assembly, the drive unit 10 is mounted on a first mounting base 201, and the pump 30 is mounted on a third mounting base 205, which is configured to be connected to the base of the pump 30.
[0198] Optionally, refer to Figure 1 The drive unit 10 is mounted on the end face of the first mounting base 201 located in the third direction z.

[0200] In this embodiment, the drive device 10 is installed on the side of the connecting bracket 20 near the first rib group 204, and the pump 30 is installed on the side of the connecting bracket 20 near the second rib group 203. This installation configuration fully considers that the drive device 10 is typically the main source of vibration in the equipment where the pump assembly is located, the vibration mode of the drive device 10, the structural form of the pump 30 when assembled with the connecting bracket 20 and the drive device 10, and the weight reduction requirements of the connecting bracket 20. (Reference) Figures 5 to 10 Based on the preceding description of the structure of the connecting bracket 20, the structure of the first rib group 204 can be set to be relatively complex, for example, including at least the aforementioned corner rib 2041, vertical rib 2043, diagonal rib 2044, first annular rib 2045, and transverse rib 2046, so as to sufficiently attenuate the vibration transmitted along the third direction z of the connecting bracket 20 generated by the drive device 10. The structure of the second rib group 203 can be set to be relatively simple, for example, including the aforementioned first rib segment 2031, second rib segment 2032, and second annular rib 2033, so as to facilitate the installation of the mounting end face 301 of the pump 30 to the connecting bracket 20 and to connect with the output shaft of the drive device 10 such as the motor, and to adapt to the weight reduction requirements of the connecting bracket 20.
[0201] Optionally, refer to Figure 1 , Figures 20 to 23The pump assembly also includes a flexible joint 40, an inlet pipe assembly 50, a reducing adapter 60, and an outlet pipe assembly 70.

The flexible joint 40 includes an elastic portion 401 and two fifth flanges 402 located at both ends of the elastic portion 401. The two fifth flanges 402 are respectively connected to the reducing adapter 60 and the inlet pipe assembly 50. The inlet pipe assembly 50 includes a first flange 501, a first inlet pipe body 502, a second inlet pipe body 503, and a first pressure measuring pipe 504. The first flange 501 is connected to the flexible joint 40, and the first pressure measuring pipe 504 is disposed in the second inlet pipe body 503. The outlet pipe assembly 70 includes a second flange 701, a second pressure measuring pipe 702, and an outlet pipe body 703. The second flange 701 is connected to the fluid outlet 303 of the pump 30, and the second pressure measuring pipe 702 is disposed in the outlet pipe body 703.
[0202] refer to Figures 16 to 19 In some embodiments of the pump assembly, the pump 30 includes a pump body 306, a fluid inlet 302, and a fluid outlet 303. The fluid inlet 302 is provided with a third rib group 304, which includes a third annular rib 3041 and a plurality of third extended ribs. The third annular rib 3041 surrounds the outer periphery of the fluid inlet 302, and the plurality of third extended ribs are distributed on the outer periphery of the fluid inlet 302 and extend along the axial direction of the fluid inlet 302. The third annular rib 3041 and the plurality of third extended ribs are arranged intersectingly, and at least one third extended rib is connected to the pump body 306.
[0203] Optionally, the number of third extension ribs is eight or more. Optionally, multiple third extension ribs are evenly distributed at intervals around the outer periphery of the fluid outlet 303.
[0204] refer to Figures 16 to 19 In some embodiments of the pump assembly, the pump 30 includes a pump body 306, a fluid inlet 302, and a fluid outlet 303. The fluid outlet 303 is provided with a fourth rib group 305, which includes a fourth annular rib 3051 and a plurality of fourth extended ribs. The fourth annular rib 3051 surrounds the outer periphery of the fluid outlet 303, and the plurality of fourth extended ribs are distributed on the outer periphery of the fluid outlet 303 and extend along the axial direction of the fluid outlet 303. The fourth annular rib 3051 and the plurality of fourth extended ribs are arranged intersectingly, and at least one fourth extended rib is connected to the pump body 306.
[0205] Optionally, the number of fourth extension ribs is eight or more. Optionally, multiple fourth extension ribs are evenly distributed at intervals around the outer periphery of the fluid outlet 303.
[0206] Optionally, refer to Figure 18 The pump 30 includes a reinforcing rib 307 connected between the fourth rib group 305 and the pump body 306.
[0207] In this embodiment, the third annular rib 3041 and multiple third extended ribs respectively form a cross-shaped vibration damping structure, and the fourth annular rib 3051 and multiple fourth extended ribs respectively form a cross-shaped vibration damping structure. This structure can significantly improve the pressure-bearing capacity of the pump 30. When the hydraulic and motor-excited vibrations inside the pump 30 are transmitted to the fluid inlet 302 or fluid outlet 303, they can be sufficiently attenuated by the cross-shaped vibration damping structure, effectively reducing the vibration output of the pump 30 in both the axial and radial directions of the pump body 306. This helps to reduce the vibration radiation of the pump 30 to the connecting bracket 20, thereby achieving the purpose of reducing the vibration of the entire equipment.
[0208] Based on the arrangement of the third rib group 304 and the fourth rib group 305 in this embodiment, the vibration acceleration level at the flange position of the fluid inlet 302 of the pump 30 is reduced from the original 131dB to 121dB, and the vibration acceleration level at the flange position of the fluid inlet 302 of the pump 30 is reduced from the original 128dB to 120dB. It can be seen that this rib arrangement can significantly reduce vibration.
[0209] In some embodiments of the pump assembly, a9 = a10, where a9 represents the width of the third annular rib 3041 and a10 represents the width of the third extended rib.
[0210] refer to Figures 16 to 19 In some embodiments of the pump assembly, the third extending rib is divided by the third annular rib 3041 into a third rib segment 3042 away from the pump body 306 and a fourth rib segment 3043 close to the pump body 306. The fourth extending rib is divided by the fourth annular rib 3051 into a fifth rib segment 3052 away from the pump body 306 and a sixth rib segment 3053 close to the pump body 306.

[0211] Figures 16 to 19 In the diagram, b7 represents the length of the third extension rib.
[0212] In this embodiment, by setting a9=a10, it is beneficial to maintain the consistency of the stiffness enhancement and vibration damping effects of the third rib group 304 in different directions of the fluid inlet 302. By setting a9=a11=a13 and h4=h3, it is beneficial to maintain the consistency of the vibration damping effects of the fourth rib group 305 and the third rib group 304. By setting b9≥1 / 3*b8, the stiffness enhancement effect of the fourth annular rib 3051 can more uniformly cover the extension area of the fourth extension rib.
