[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] like Figure 1-6 As shown, an energy-saving hydraulic pump proposed in an embodiment of the utility model comprises a housing 1, wherein the housing 1 comprises a left plate 101, a connecting plate 102, a fixing plate 103 and a driving plate 104, wherein the left plate 101, the connecting plate 102 and the fixing plate 103 are fixedly connected to the driving plate 104 by bolts, a mute component 2 is provided at the bottom of the housing 1, the mute component 2 comprises an upper plate 201, one end of the upper plate 201 is fixedly connected to a spring column 202, the bottom of the spring column 202 is fixedly connected to a lower plate 203, the bottom of the spring column 202 is fixedly connected to a mounting plate 3, a large bolt 4 is threadedly connected to the mounting plate 3, a mounting hole 5 for mounting with an external connecting structure is provided on the mounting plate 3, a driving shaft 6 is plugged into the interior of the housing 1, one end of the driving shaft 6 is fixedly connected to a driving toothed disc 7, a driven toothed disc 8 is meshed on the driving toothed disc 7, and an inlet and outlet flow passage 9 is provided on the housing 1;

[0027] It is composed of a shell 1, including a left plate 101, a connecting plate 102, a fixing plate 103 and a driving plate 104, which are fixedly connected by bolts to ensure the stability of the shell 1.

[0028] A mute component 2 is provided at the bottom, which is connected to the lower plate 203 by an upper plate 201 through spring columns 202, and the spring columns 202 are arranged in a filling array to enhance the mute effect.

[0029] The bottom of the mute component 2 is connected to the mounting plate 3 via a large bolt 4, and the mounting plate 3 is provided with a mounting hole 5 for connecting to the outside.

[0030] A driving shaft 6 is inserted into the housing 1 , one end of which is connected to a driving gear disc 7 and meshes with a driven gear disc 8 .

[0031] The inlet and outlet flow channels 9 are provided with channels on the connecting plate 102 , the fixing plate 103 and the driving plate 104 and are of symmetrical structure.

[0032] When the drive shaft 6 starts to rotate, it drives the driving toothed disc 7 to rotate. The driving toothed disc 7 and the driven toothed disc 8 mesh with each other, thereby transmitting power to the driven toothed disc 8, causing it to also start to rotate.

[0033] In this process, the liquid enters and flows out of the housing 1 through the inlet and outlet flow channels 9. The channel design of the inlet and outlet flow channels 9 on the connecting plate 102, the fixing plate 103 and the driving plate 104 ensures that the liquid can flow smoothly. Since the inlet and outlet flow channels 9 are symmetrical structures, this helps the liquid to maintain balance and stability when flowing in the pump, thereby improving the working efficiency and uniformity of the flow rate.

[0034] When the hydraulic pump is working, vibration and noise may be generated. At this time, the silent component 2 comes into play. The spring column 202 between the upper plate 201 and the lower plate 203 can absorb and buffer the vibration energy and reduce the transmission of vibration. At the same time, the filling array structure of the spring column 202 further enhances its shock absorption and noise reduction effect, making the entire hydraulic pump quieter during operation and reducing the impact on the surrounding environment.

[0035] The mounting plate 3 is fixedly connected to the mute assembly 2 and the housing 1 by means of large bolts 4, thus ensuring the stability of the entire hydraulic pump in the working position. The mounting holes 5 on the mounting plate 3 facilitate the hydraulic pump to be firmly mounted on the external structure, ensuring that it can work normally without shaking or shifting.

[0036] like Figure 2 As shown, in some embodiments, the spring column 202 filling array is arranged between the upper plate 201 and the lower plate 203, and the spring column 202 filling array is arranged between the upper plate 201 and the lower plate 203, and its function is to absorb and buffer vibration energy and reduce the transmission of vibration. The design of this filling array can improve the shock absorption and noise reduction effect of the silent component 2, making the entire hydraulic pump quieter during operation and reducing the impact on the surrounding environment.

[0037] like Figure 2 As shown, in some embodiments, the large bolt 4 penetrates the mounting plate 3 and the mute component 2 and is threadedly connected to a place inside the housing 1; first, it realizes the fastening connection of the mounting plate 3, the mute component 2 and the housing 1. This ensures that during the operation of the hydraulic pump, these components will not be relatively displaced or loosened due to vibration or other external forces, thereby ensuring the stability and reliability of the entire structure.

[0038] Secondly, the threaded connection with the inside of the housing 1 further enhances the firmness of the installation, so that the hydraulic pump can be stably fixed in its working position, withstand various forces generated during operation, and ensure its normal operation.

[0039] Furthermore, this connection method helps to effectively transfer the external load borne by the mounting plate 3 to the housing 1, disperse the stress, and avoid local stress concentration leading to component damage. At the same time, it also provides a solid support for the silent component 2, enabling it to better perform the functions of shock absorption and noise reduction.

[0040] like Figure 3 As shown, in some embodiments, the upper plate 201 and the lower plate 203 of the mute component 2 are provided with holes adapted to the large bolts 4. This design allows the large bolts 4 to pass through the upper plate 201 and the lower plate 203 smoothly, thereby tightly connecting them with the mounting plate 3 and the housing 1. Such matching holes ensure the accuracy and stability of the installation of the large bolts 4, avoiding the occurrence of installation difficulties or loose connections due to mismatched holes. At the same time, the close fit between these holes and the large bolts 4 also helps to maintain the position of the entire mute component 2 fixed during operation, preventing it from shaking or shifting when the hydraulic pump is running, thereby ensuring the continued effectiveness of the mute effect.

[0041] like Figure 4 , 5 As shown in Figure 6, in some embodiments, the inlet and outlet flow channels 9 are provided with channels in the connecting plate 102, the fixing plate 103 and the driving plate 104, and the inlet and outlet flow channels 9 are symmetrical structures. The symmetrical structure helps to evenly distribute the fluid in the inlet and outlet flow channels 9, thereby improving the working efficiency and stability of the hydraulic system. Reasonable flow channel design can reduce the resistance during the fluid flow process, reduce pressure loss, and improve the energy utilization rate of the system.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
