Description

Technical Field

[0001] This invention relates to the field of hydraulic pump station technology, and more particularly to an integrated pump station for extrusion equipment. Background Technology

[0002] In the field of hydraulic equipment, a pump station refers to a hydraulic power unit composed of components such as pumps, oil tanks, valves, and controllers. It is primarily used to provide hydraulic power and is a core component of the hydraulic system, commonly used in extrusion equipment, casting machinery, and other fields. A pump station typically includes an oil tank, a circulating pump connected to the oil tank, a cooler for cooling the oil, a filter tank for filtration, a main oil pipe connected to the circulating pump, a suction pipe for drawing oil from the main oil pipe, an output pump connected to the suction pipe, and an outlet pipe for outputting hydraulic oil from the output pump.

[0003] See Figure 2 Traditional pump stations install the circulating pump unit 2' and cooler 3' on the same platform to form the input module, and the output pump unit 4' and main suction pipe group 51' on another platform to form the output module. The cooler 3' and main suction pipe group 51' are connected via cooling pipes. The oil tank is located above both platforms and connected to both the circulating pump unit 2' and main suction pipe group 51'. This connection and fixing method uses two platforms to fix the input and output modules. Because the installation references for both are not easily unified, their positions require multiple adjustments to align the connecting pipes. Therefore, the installation accuracy and efficiency are low, and the installation is difficult. Furthermore, the oil outlet pipe 52' is long and complex in shape, requiring numerous high-pressure pipe clamps 524' for fixing, increasing installation cost and complexity, increasing pressure loss in the oil outlet pipe, and reducing energy transfer efficiency. Summary of the Invention

[0009] As an improvement to the above solution, the connecting assembly further includes a connecting pipe, one end of the second cooling pipe is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the second main oil suction pipe.

[0010] The connecting pipe spans between the first mounting bracket and the second mounting bracket.

[0011] As an improvement to the above solution, a filter oil tank assembly is also included, which includes a first filter oil tank and a second filter oil tank. The first filter oil tank is located between the first circulating pump and the first main suction pipe, and the second filter oil tank is located between the second circulating pump and the second main suction pipe.

[0012] As an improvement to the above solution, the connecting assembly further includes a sub-suction pipe group, which includes a first sub-suction pipe and a second sub-suction pipe. The first sub-suction pipe is connected between the first output pump and the first main suction pipe, and the second sub-suction pipe is connected between the second output pump and the second main suction pipe.

[0013] As an improvement to the above solution, the oil outlet pipe assembly includes a first oil outlet pipe and a second oil outlet pipe. One end of the first oil outlet pipe is located at the lower part of the first mounting bracket and is connected to the first output pump.

[0018] Implementing this invention has the following beneficial effects:

[0019] This invention relates to an integrated pump station for extrusion equipment, comprising a mounting frame assembly, a circulating pump assembly, a cooler, an output pump assembly, and a connecting assembly. The main suction pipe assembly of the connecting assembly connects the circulating pump assembly, the cooler, and the output pump assembly. All components—the circulating pump assembly, the cooler, the output pump assembly, and the main suction pipe assembly—are fixed to the mounting frame assembly. This unifies the circulating pump assembly, the cooler, the output pump assembly, and the main suction pipe assembly onto a single mounting base, eliminating the need to adjust height differences during installation, reducing installation difficulty, improving fit accuracy, saving installation and adjustment time, and increasing installation efficiency. Furthermore, by placing the outlet pipe assembly at the bottom of the mounting frame and below the output pump assembly, the length of the outlet pipe assembly is effectively shortened, resulting in a more regular shape. This reduces the use of high-pressure pipe clamps, installation time, and installation costs, while also reducing pressure drop in the outlet pipe assembly and improving transmission efficiency.

[0021] Figure 2 This is a schematic diagram of the existing pumping station. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0023] See Figure 1 This invention discloses an integrated pump station for extrusion equipment, comprising a mounting frame assembly 1, a circulating pump assembly 2, a cooler 3, and an output pump assembly 4. The circulating pump assembly 2, the cooler 3, and the output pump assembly 4 are all fixed to the mounting frame assembly 1. The mounting frame assembly 1 is provided with a mounting platform, and the circulating pump assembly 2, the cooler 3, and the output pump assembly 4 are all fixed to the mounting platform of the mounting frame assembly 1. The mounting reference for the circulating pump assembly 2, the cooler 3, and the output pump assembly 4 is the mounting platform. The circulating pump assembly 2 is connected to the cooler 3, and the output pump assembly 4 is connected to both the circulating pump assembly 2 and the cooler 3. The circulating pump assembly 2 is connected to an upper oil tank, allowing hydraulic oil from the tank to enter the circulating pump assembly 2.

[0024] To connect the various components, the integrated pump station for the extrusion equipment also includes a connecting assembly 5. The connecting assembly 5 includes a main suction pipe assembly 51 and an outlet pipe assembly 52. ​​The main suction pipe assembly 51 is fixed to the mounting frame assembly 1. One end of the main suction pipe assembly 51 is connected to the circulating pump assembly 2, and the other end is connected to the cooler 3. The circulating pump assembly 2 pumps hydraulic oil into the main suction pipe assembly 51. The end of the main suction pipe assembly 51 is connected to the cooler 3. The circulating pump assembly 2 pumps excess hydraulic oil into the cooler 3 for cooling through the main suction pipe assembly 51. After cooling, the hydraulic oil returns to the upper oil tank. Simultaneously, the side of the main suction pipe assembly 51 is connected to the outlet pump assembly 4, allowing the hydraulic oil in the main suction pipe assembly 51 to be both transported and cooled simultaneously. The oil outlet pipe assembly 52 is located at the output end of the output pump assembly 4. The oil outlet pipe assembly 52 is fixed to the bottom of the mounting frame and located below the output pump assembly 4. The output pump assembly 4 can output hydraulic oil to the extrusion equipment through the oil outlet pipe assembly 52.

[0025] In this invention, by fixing the circulating pump group 2, the cooler 3, the output pump group 4, and the main suction pipe group 51 to the mounting frame group 1, a unified installation benchmark can be achieved, eliminating the need for height adjustment, simplifying the installation process, and improving installation accuracy. Moreover, during transportation, multiple pipes do not need to be disassembled, making on-site installation more convenient. In addition, the cooler 3 is connected to the main suction pipe group 51, and the main suction pipe group 51 simultaneously distributes hydraulic oil to the output pump group 4, achieving the effect of simultaneous distribution and cooling. Furthermore, the oil outlet pipe group 52 is fixed to the bottom of the mounting frame group 1 and located below the output pump group 4, ensuring that the position of the output pump group 4 corresponds to the position of the oil outlet pipe group 52. This shortens the extension distance of the oil outlet pipe group 52, resulting in a more regular shape for the oil outlet pipe group 52, facilitating its arrangement and fixation, and reducing the use of high-pressure pipe clamps 524.

[0026] The beneficial effects of the embodiments of the present invention are as follows:

[0027] The integrated pump station for extrusion equipment in this embodiment of the invention includes a mounting frame assembly 1, a circulating pump assembly 2, a cooler 3, an output pump assembly 4, and a connecting assembly 5. The main suction pipe assembly 51 of the connecting assembly 5 connects the circulating pump assembly 2, the cooler 3, and the output pump assembly 4. The circulating pump assembly 2, the cooler 3, the output pump assembly 4, and the main suction pipe assembly 51 are all fixed on the mounting frame assembly 1. This unifies the circulating pump assembly 2, the cooler 3, the output pump assembly 4, and the main suction pipe assembly 51 onto a single installation reference. During installation, there is no need to adjust the height differences between them, reducing installation difficulty, improving the precision of the fit, saving installation and adjustment time, and increasing installation efficiency. Furthermore, by placing the oil outlet pipe assembly 52 at the bottom of the mounting bracket and below the output pump assembly 4, the length of the oil outlet pipe assembly 52 can be effectively shortened, making the shape of the oil outlet pipe assembly 52 regular. This reduces the use of high-pressure pipe clamps 524, installation time, and installation costs, while also reducing the pressure drop of the oil outlet pipe assembly 52 and improving transmission efficiency.

[0028] Specifically, to increase the conveying capacity, the mounting frame group 1 includes a first mounting frame 11 and a second mounting frame 12; the circulating pump group 2 includes a first circulating pump 21 and a second circulating pump 22; the first circulating pump 21 and the second circulating pump 22 are simultaneously connected to the oil tank above for dual output; the output pump group 4 includes a first output pump 41 and a second output pump 42; and the main suction pipe group 51 includes a first main suction pipe 511 and a second main suction pipe 512. The first circulating pump 21, the first output pump 41, and the first main suction pipe 511 are all fixed on the first mounting frame 11, and the second circulating pump 22, the second output pump 42, and the second main suction pipe 512 are all fixed on the second mounting frame 12.

[0029] The cooler 3 is fixed on the first mounting bracket 11. The connecting assembly 5 also includes a cooling pipe group 53, which includes a main cooling pipe 531, a first cooling pipe 532, a second cooling pipe 533, and a cooling oil return pipe 534. The main cooling pipe 531 is connected to the cooler 3. The first cooling pipe 532 and the second cooling pipe 533 are respectively led out from the main cooling pipe 531. The first cooling pipe 532 is connected to the end of the first main oil suction pipe 511 that is away from the first circulating pump 21, and the second cooling pipe 533 is connected to the end of the second main oil suction pipe 512 that is away from the second circulating pump 22. In this way, after the first circulating pump 21 introduces hydraulic oil into one end of the first main suction pipe 511, the hydraulic oil will be cooled at the other end of the first main suction pipe 511. The second circulating pump 22 does the same. The middle section of the first main suction pipe 511 and the second main suction pipe 512 will distribute the hydraulic oil. Therefore, the hydraulic oil is distributed while being cooled by the cooler 3, achieving the effect of simultaneous cooling and distribution. One end of the cooling return pipe 534 is connected to the output port of the cooler 3, and the other end of the cooling return pipe 534 is connected to the external oil tank above. The cooled hydraulic oil will return to the oil tank through the cooling return pipe 534. At the same time, the cooled hydraulic oil returning to the oil tank will have a cooling effect, which can cool the hydraulic oil in the oil tank, achieving the effect of simultaneous output and cooling.

[0030] To facilitate simultaneous cooling of excess hydraulic oil in the second main suction pipe 512, the connecting assembly 5 further includes a connecting pipe 55. One end of the main cooling pipe 531, away from the cooler 3, is connected to an external oil tank. One end of the second cooling pipe 533 is connected to one end of the connecting pipe 55, and the other end of the connecting pipe 55 is connected to the second main suction pipe 512. The connecting pipe 55 spans between the first mounting bracket 11 and the second mounting bracket 12. During transportation, only the connecting pipe 55 needs to be removed; the components on the first mounting bracket 11 and the second mounting bracket 12 do not need to be removed, facilitating transportation. During installation, only the connecting pipe 55 needs to be installed. Compared to the traditional pump station installation process that requires connecting multiple pipes, this saves a significant number of installation steps and time.

[0031] The integrated pump station for the extrusion equipment also includes a filter oil tank group 6, which includes a first filter oil tank 61 and a second filter oil tank 62. The first filter oil tank 61 is located between the first circulating pump 21 and the first main suction pipe 511, and the second filter oil tank 62 is located between the second circulating pump 22 and the second main suction pipe 512. The first filter oil tank 61 and the second filter oil tank 62 can filter the hydraulic oil before it enters the first main suction pipe 511 and the second main suction pipe 512, respectively, to prevent impurities from entering the output pump group 4. The connecting assembly 5 further includes a sub-suction pipe group 54, which includes a first sub-suction pipe 541 and a second sub-suction pipe 542. The first sub-suction pipe 541 is connected between the first output pump 41 and the first main suction pipe 511, and the second sub-suction pipe 542 is connected between the second output pump 42 and the second main suction pipe 512. The first output pump 41 draws hydraulic oil from the first main suction pipe 511 through the first sub-suction pipe 541, and the second output pump 42 draws hydraulic oil from the second main suction pipe 512 through the second sub-suction pipe 542.

[0032] The oil outlet pipe assembly 52 further includes a first oil outlet pipe 521 and a second oil outlet pipe 522. One end of the first oil outlet pipe 521 is located at the lower part of the first mounting bracket 11 and is connected to the first output pump 41. The other end of the first oil outlet pipe 521 extends from the output side of the first mounting bracket 11. One end of the second oil outlet pipe 522 is located at the lower part of the second mounting bracket 12 and is connected to the second output pump 42. The other end of the second oil outlet pipe 522 extends from the output side of the second mounting bracket 12. The first oil outlet pipe 521 and the second oil outlet pipe 522 are output from the same side of the first mounting bracket 11 and the second mounting bracket 12. In traditional pump stations, the oil outlet pipe extends from the side of the mounting frame, with numerous bends in the middle. This not only increases the length of the oil outlet pipe but also requires a large number of high-pressure pipe clamps 524 for fixation. However, in this embodiment of the invention, the first oil outlet pipe 521 and the second oil outlet pipe 522 are directly fixed to the bottom of the mounting frame, without needing to extend to the side of the mounting frame. Therefore, the overall length of the first oil outlet pipe 521 and the second oil outlet pipe 522 is shorter, and only high-pressure pipe clamps 524 need to be installed at both ends of the first oil outlet pipe 521 and the second oil outlet pipe 522. The number of high-pressure pipe clamps 524 required is reduced, and the number of fixing steps is also reduced.

[0033] There are multiple first output pumps 41 and multiple second output pumps 42, which are distributed along the length direction of the first mounting bracket 11 and the length direction of the second mounting bracket 12, respectively. The multiple first output pumps 41 correspond to multiple first oil suction pipes 541 and multiple first oil discharge pipes 521, and the multiple second output pumps 42 correspond to multiple second oil suction pipes 542 and multiple second oil discharge pipes 522.

[0034] The first main suction pipe 511 and the second main suction pipe 512 are respectively arranged along the length direction of the first mounting bracket 11 and the second mounting bracket 12. A plurality of first output pumps 41 are distributed on the first main suction pipe 511, and a plurality of second output pumps 42 are distributed on the second main suction pipe 512. Low-pressure pipe clamps 513 are provided on both ends of the first main suction pipe 511 and the second main suction pipe 512 for fixing the first main suction pipe 511 and the second main suction pipe 512.

[0035] The output pump group 4 further includes a third output pump 43. The first output pump 41 and the second output pump 42 serve as main pumps, and the third output pump 43 serves as an auxiliary pump. The oil outlet pipe group 52 further includes a third oil outlet pipe 523. The third output pump 43 is fixed on the second mounting bracket 12. The branch suction pipe group 54 further includes a third branch suction pipe 543. The input end of the third output pump 43 is connected to the third branch suction pipe 543, and the output end of the third output pump 43 is connected to the third oil outlet pipe 523. One end of the third oil outlet pipe 523 is located at the lower part of the second mounting bracket 12, and the other end extends from the output side of the second mounting bracket 12. Part of the hydraulic oil that the second circulation pump 22 passes into the second main suction pipe 512 can enter the third output pump 43 through the third branch suction pipe 543 and be output from the third oil outlet pipe 523.

[0036] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
