The cooler 3' is connected to the main oil suction pipe group 51' through a cooling pipe. The oil tank is located above the two platforms and is connected to the circulating pump group 2' and the main oil suction pipe group 51' respectively. This connection and fixing method uses two platforms to fix the input module and the output module respectively.

Therefore, the installation accuracy and efficiency are low, and the installation difficulty is great. In addition, the distance of the oil outlet pipe 52' is long and the shape is complex. It requires a large number of high-pressure pipe clamps 524' for fixing, which increases the installation cost and complexity, and also increases the pressure loss of the oil outlet pipe, reducing the energy transfer efficiency.

In addition, the oil outlet pipe group 52 is fixed to the bottom of the mounting frame group 1 and is located below the output pump group 4, so that the position of the output pump group 4 can correspond to the position of the oil outlet pipe group 52, and the extension distance of the oil outlet pipe group 52 can be shortened, so that the shape of the oil outlet pipe group 52 can be regular, which is convenient for arrangement and fixation, and the use of high-pressure pipe clamps 524 can be reduced.

[0026] The beneficial effects of the embodiments of the utility model are as follows:

[0027] The utility model embodiment of the integrated pump station for extrusion equipment is provided with a mounting frame group 1, a circulation pump group 2, a cooler 3, an output pump group 4 and a connecting assembly 5, wherein a main oil suction pipe group 51 of the connecting assembly 5 is connected between the circulation pump group 2, the cooler 3 and the output pump group 4, wherein the circulation pump group 2, the cooler 3, the output pump group 4 and the main oil suction pipe group 51 are all fixed on the mounting frame group 1, and the circulation pump group 2, the cooler 3, the output pump group 4 and the main oil suction pipe group 51 can be unified on a mounting reference, and there is no need to adjust the height difference between them during installation, which reduces the difficulty of installation, can improve the accuracy of matching, saves installation adjustment time, and improves installation efficiency. Moreover, by arranging the oil outlet pipe group 52 at the bottom of the mounting frame group 1 and below the output pump group 4, the length of the oil outlet pipe group 52 can be effectively shortened, and the shape of the oil outlet pipe group 52 can be made regular. While reducing the use of the high-pressure pipe clamp 524, reducing the installation time and installation cost, the pressure drop of the oil outlet pipe group 52 can be reduced, thereby improving the transmission efficiency.

[0028] Specifically, in order 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, the main oil suction pipe group 51 includes a first main oil suction pipe 511 and a second main oil suction pipe 512, the first circulating pump 21, the first output pump 41 and the first main oil 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 oil suction pipe 512 are all fixed on the second mounting frame 12.

[0029] The cooler 3 is fixed on the first mounting frame 11, and the connecting assembly 5 also includes a cooling pipe group 53, and the cooling pipe group 53 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, wherein the first cooling pipe 532 is connected to an end of the first main oil suction pipe 511 away from the first circulating pump 21, and the second cooling pipe 533 is connected to an end of the second main oil suction pipe 512 away from the second circulating pump 22. In this way, after the first circulation pump 21 passes the hydraulic oil into one end of the first main oil suction pipe 511, the hydraulic oil will be cooled at the other end of the first main oil suction pipe 511, and the second circulation pump 22 is the same. The middle sections of the first main oil suction pipe 511 and the second main oil suction pipe 512 will distribute the hydraulic oil. Therefore, the hydraulic oil is distributed while receiving cooling from the cooler 3, achieving the effect of simultaneous cooling and distribution. One end of the cooling return oil pipe 534 is connected to the output port of the cooler 3, and the other end of the cooling return oil pipe 534 is connected to the external oil tank above. The cooled hydraulic oil will return to the oil tank through the cooling return oil pipe 534. At the same time, the cooled hydraulic oil returning to the oil tank will form a cooling effect, which can cool the hydraulic oil in the oil tank and achieve the effect of cooling while outputting.

[0030] In order to facilitate cooling of the excess hydraulic oil in the second main oil suction pipe 512 at the same time, the connection assembly 5 also includes a connection pipe 55.

The connection pipe 55 spans between the first mounting frame 11 and the second mounting frame 12. During transportation, only the connection pipe 55 needs to be removed, and the components on the first mounting frame 11 and the second mounting frame 12 do not need to be removed, which is convenient for transportation. During installation, only the connection pipe 55 needs to be installed.

[0031] The integrated pump station for 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 arranged between the first circulation pump 21 and the first main oil suction pipe 511, and the second filter oil tank 62 is arranged between the second circulation pump 22 and the second main oil suction pipe 512. The first filter oil tank 61 and the second filter oil tank 62 can filter the hydraulic oil before entering the first main oil suction pipe 511 and the second main oil suction pipe 512 respectively to prevent impurities from entering the output pump group 4. The connecting assembly 5 also includes a branch oil suction pipe group 54, which includes a first branch oil suction pipe 541 and a second branch oil suction pipe 542. The first branch oil suction pipe 541 is connected between the first output pump 41 and the first main oil suction pipe 511, and the second branch oil suction pipe 542 is connected between the second output pump 42 and the second main oil suction pipe 512.

The oil outlet pipe of a traditional pump station is led out from the side of the mounting frame, and there are many bending positions in the middle of the oil outlet pipe, which not only increases the length of the oil outlet pipe, but also requires the use of more high-pressure pipe clamps 524 for fixing. In the embodiment of the utility model, the first oil outlet pipe 521 and the second oil outlet pipe 522 are directly fixed to the bottom of the mounting frame and do not need to be led out 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 it is only necessary to set high-pressure pipe clamps 524 on the sides of both ends of the first oil outlet pipe 521 and the second oil outlet pipe 522.
