[0047] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] like Figures 1 to 5 As shown, the reciprocating pump base structure of the present invention includes a base 1, an oil supply pipeline 2, a cooling pipeline 3, a maintenance pipeline 4, a first partition plate 5 and a sealing assembly 6.

[0049] like Figures 1 to 5 As shown, the base 1 is a hollow structure, with a first accommodating chamber 101 and a second accommodating chamber 102 formed therein. The first accommodating chamber 101 is used to store lubricating oil. The oil supply line 2 passes through the second accommodating chamber 102, and one end is connected to the first accommodating chamber 101. The cooling line 3 is sleeved on the portion of the oil supply line 2 located in the second accommodating chamber 102, and the end of the cooling line 3 is led out to the outside of the second accommodating chamber 102. The maintenance line 4 is connected to and passes through the middle section of the oil supply line 2.

[0050] As described above, the base 1 is divided into a first accommodating chamber 101 and a second accommodating chamber 102. The first accommodating chamber 101 is used to store lubricating oil, and the lubricating oil is output through the oil supply pipeline 2.

[0051] Since the oil supply line 2 passes through the second accommodating chamber 102, a cooling line 3 can be provided in the second accommodating chamber 102 to cool the lubricating oil in the oil supply line 2 to prevent the lubricating oil from overheating;

[0052] Maintenance line 4 can be used for external circulation filtration or replacement of lubricating oil;

[0053] With this structure, most of the volume of the oil supply pipeline 2 and the cooling pipeline 3 is located in the second accommodating cavity 102, which realizes the combination with the base 1. It not only has the advantages of regular layout and easy maintenance, but also reduces the floor space of the equipment.

[0054] like Figure 5 As shown, the oil supply pipeline 2 includes an oil outlet pipe 21, a connecting pipe 22 and a connecting pipe 23, wherein the oil outlet pipe 21 is connected to the base 1 and penetrates the first accommodating chamber 101; the connecting pipe 22 penetrates the second accommodating chamber 102; the connecting pipe 23 is located outside the base 1, and one end of the connecting pipe 23 is connected to and penetrates the oil outlet pipe 21, and the other end is connected to and penetrates the connecting pipe 22;

[0055] As shown in the above structure, in the oil supply pipeline 2, the oil outlet pipe 21 outputs the lubricating oil from the first accommodating chamber 101 and transports it to the connecting pipe 22 through the connecting pipe 23. When the lubricating oil flows in the connecting pipe 22, the lubricating oil is dissipated and cooled by the cooling medium flowing in the cooling pipeline 3.

[0056] Specifically, the other end of the connecting pipe 22 is used to connect to a pump such as a gear pump to achieve the suction of lubricating oil.

[0057] In some embodiments, the oil supply line 2 can be replaced by an oil return line to cool the lubricating oil when it is returned to the first accommodating chamber 101 .

[0058] like Figure 3 As shown, the cooling pipe 3 includes a sleeve pipe 31, an input pipe 32 and an output pipe 33, wherein the sleeve pipe 31 is sleeved on the connecting pipe 22; the input pipe 32 is connected to and passes through one end of the sleeve pipe 31; the output pipe 33 is connected to and passes through the other end of the sleeve pipe 31, and the length of the output pipe 33 is greater than that of the input pipe 32;

[0059] As shown in the above structure, the input pipe 32 and the output pipe 33 of the cooling pipeline 3 are used to connect to the cooling unit, and the cooling unit is used to cool the cooling medium;

[0060] During operation, the cooling medium is delivered to the sleeve tube 31 through the input pipe 32. The cooling medium adheres to the inner wall of the sleeve tube 31 and the outer wall of the connecting pipe 22 of the oil supply pipeline 2 and circulates, thereby removing the heat of the lubricating oil in the oil supply pipeline 2.

[0061] The output pipe 33 is arranged to be relatively long, so that passive heat dissipation can be achieved by relying on the pipe wall of the output pipe 33 to reduce the load of the cooling unit.

[0062] like Figure 3 As shown, the cooling pipeline 3 further includes a first heat dissipation fin 34, and the output pipe 33 has a heat dissipation section 331 parallel to the sleeve pipe 31; the first heat dissipation fin 34 is arranged on the outer wall of the heat dissipation section 331;

[0063] As shown in the above structure, the output tube 33 has a heat dissipation section 331 parallel to the sleeve tube 31. In this way, the heat dissipation section 331 can be arranged longer, which allows more first heat dissipation fins 34 to be provided on the heat dissipation section 331. The first heat dissipation fins 34 can improve the passive heat dissipation effect.

[0064] like Figure 4 and Figure 5 As shown, the first partition 5 is disposed in the base 1 , and the first partition 5 cooperates with the base 1 to separate a second accommodating chamber 102 and a third accommodating chamber 103 ; the maintenance pipeline 4 is located in the third accommodating chamber 103 ;

[0065] As in the above structure, by setting the first partition 5, the second accommodating chamber 102 and the third accommodating chamber 103 are separated, so that the maintenance pipeline 4 can be installed alone in the third accommodating chamber 103, and the cooling pipeline 3 is located in the second accommodating chamber 102, thereby realizing medium isolation.

[0066] like Figure 1 As shown, the sealing assembly 6 includes a first sealing plate 61, a second sealing plate 62 and a third sealing plate 63, wherein the first sealing plate 61 cooperates with the base 1 to seal the third accommodating cavity 103; the second sealing plate 62 and the third sealing plate 63 are arranged in parallel and seal the second accommodating cavity 102; the port of the cooling pipeline 3 passes through the second sealing plate 62;

[0067] As described above, the maintenance line 4 is used for external circulation, filtration, discharge, and replacement of the lubricating oil. The third accommodating chamber 103 for setting the maintenance line 4 is individually sealed by the first sealing plate 61.

[0068] The second accommodating chamber 102 for accommodating the cooling pipe 3 is sealed by the second sealing plate 62 and the third sealing plate 63, so that the port of the cooling pipe 3 can pass through the second sealing plate 62. The second sealing plate 62 does not need to be disassembled. During maintenance, only the third sealing plate 63 needs to be disassembled to ensure the convenience of maintenance.

[0069] like Figure 1 As shown, the second accommodating chamber 102 is equipped with a cooling fan, and the third sealing plate 63 is provided with a ventilation grille 601;

[0070] As shown in the above structure, the cooling fan is not shown in the figure. It is placed in the second accommodating cavity 102, and the third sealing plate 63 is provided with a ventilation grille 601. In this way, when cooling is performed, the cooling fan can blow on the first cooling fins 34, and the hot air is discharged through the ventilation grille 601, thereby effectively improving the heat dissipation effect.

[0071] like Figure 5 As shown, the base 1 is a rectangular box structure, comprising a large panel 11, a side panel 12, and a second partition 13. Two large panels 11 are provided opposite each other; three side panels 12 are provided between the two large panels 11 in a U-shaped arrangement; the second partition 13 is provided between the two opposite side panels 12 and connected to the two side panels 12 and the two large panels 11 to form a sealed first accommodating chamber 101 and a second accommodating chamber 102 open on one side.

[0072] As shown in the above structure, when constructing the base 1, the three side panels 12 are arranged between the two large panels 11, so that the whole has an opening, and a second partition 13 is arranged inside the opening to form a sealed first accommodating cavity 101;

[0073] One end of the first partition plate 5 is connected to the second partition plate 13 to form a second accommodating chamber 102 and a third accommodating chamber 103. The three accommodating chambers are used to store or house the lubricating oil, the cooling pipe 3, and the maintenance pipe 4, respectively.

[0074] The oil supply pipeline 2 passes through the second accommodating chamber 102 and the third accommodating chamber 103 .

[0075] like Figure 1 and Figure 5 As shown, the base 1 further includes a reinforcing plate 14 and a rib plate 15, wherein two reinforcing plates 14 are provided on a single side panel 12, and the two reinforcing plates 14 are parallel to each other; a plurality of rib plates 15 are provided in parallel between the two reinforcing plates 14, and the rib plates 15 are perpendicular to the reinforcing plates 14 and are welded;

[0076] As described above, since the base structure needs to support the reciprocating pump, a reinforcing plate 14 and a rib plate 15 are provided. When the rib plate 15 is provided, it is also welded to the side panel 12 to ensure structural strength and high rigidity.

[0077] like Figure 1 and Figure 5 As shown, the base 1 further includes a second heat dissipation fin 16 , which is disposed on the side panel 12 , and the thickness of the side panel 12 is less than that of the large panel 11 ;

[0078] As in the above structure, by providing the second heat dissipation fins 16 on the side panel 12 and reducing the thickness of the side panel 12, it is beneficial for heat to be transferred to the second heat dissipation fins 16, thereby utilizing the body of the base 1 to achieve a heat dissipation effect;

[0079] At the same time, due to the structural reinforcement of the reinforcing plate 14 and the rib plate 15, the overall structure can be guaranteed to be stable, which complements the thinned side panel 12 and ensures the stability of the application.

[0080] Specific implementation steps:

[0081] Among them, in the oil supply pipeline 2, the end of the connecting pipe 22 away from the connecting pipe 23 is connected to the gear pump for sucking lubricating oil; and the oil outlet of the gear pump is connected to the position where the reciprocating pump needs to be lubricated, and the oil outlet of the reciprocating pump is connected to the base 1 and communicated with the first accommodating chamber 101 to realize a circulating oil circuit;

[0082] During lubrication, the lubricating oil enters the reciprocating pump through the oil outlet pipe 21, the connecting pipe 23 and the connecting pipe 22 in sequence; when the lubricating oil flows through the connecting pipe 22, heat is dissipated;

[0083] The input pipe 32 of the cooling line 3 is connected to the coolant unit, and the cooling medium is fed into the sleeve pipe 31. The cooling medium exchanges heat with the lubricating oil through the wall of the connecting pipe 22, and then flows back to the cooling unit through the output pipe 33 for cooling. The cycle is repeated to achieve heat dissipation.

[0084] At the same time, a cooling fan is installed in the second accommodating chamber 102. When the cooling medium flows through the output pipe 33, the heat is dissipated through the output pipe 33 and the first cooling fins 34. At this time, the fan blows away the heat to improve the heat dissipation effect.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
