Description

Technical Field

[0001] The present application relates to the technical field of lubricating oil production, and in particular to a cooling device for lubricating oil production. Background Art

[0002] The oil cooler is a turbine oil cooling device used in conjunction with steam turbines in power systems. The oil cooler is a smooth tube surface type and uses circulating water as a medium to achieve heat exchange, thereby ensuring that the bearing inlet oil temperature reaches the specified value and ensures the normal operation of the unit. The lubricating oil has a high temperature after production, and a cooling device will be used to cool it.

[0003] Some existing oil coolers are equipped with multiple cold oil pipes. The lubricating oil passes through different cold oil pipes, which greatly improves the cooling efficiency. However, the existing cold oil pipes are fixed, and the multiple pipes squeeze each other. Although the stability is high, it is inconvenient to disassemble and clean the blocked cold oil pipes or replace the damaged pipes, and the operation is relatively troublesome. Utility Model Content

[0004] In order to solve the problem, the present application provides a cooling device for lubricating oil manufacturing.

[0005] The present application provides a cooling device for lubricating oil manufacturing using the following technical solution:

[0006] A cooling device for lubricating oil manufacturing, comprising an oil cooler pipe body and an oil cooler pipe, both ends of the oil cooler pipe body are fixed with connecting flange pipes, a sealing plate is fixed on the connecting flange pipe, and a pair of through pipes are fixed on the oil cooler pipe body;

[0007] It also includes a limiting mechanism, which is installed inside the oil cooler tube body and is used to limit and fix the multiple oil cooler tubes.

[0008] Preferably, the limiting mechanism comprises an embedded tube embedded in the oil cooler tube body, the diameter of the embedded tube is the same as the inner diameter of the oil cooler tube body, and the embedded tube is slidably connected to the oil cooler tube body.

[0009] Preferably, a limiting cylinder is embedded inside the embedded tube, a plurality of limiting long holes are opened on the limiting cylinder, and the cold oil pipe is embedded in the limiting long holes.

[0010] Preferably, the limiting cylinder is made of metal, and the limiting cylinder is slidably connected to the cold oil pipe.

[0011] Preferably, the embedded tube is made of metal, and the embedded tube is slidably connected to the limiting cylinder.

[0012] Preferably, a take-out groove is provided at the end of the embedded tube, between the embedded tube and the limiting cylinder, and the end of the cold oil pipe is located in the take-out groove.

[0013] Preferably, the length of the cooling oil pipe is equal to the length of the embedded pipe.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By setting the embedded tube, the limiting cylinder, the limiting long hole and the extraction groove, when replacing the cold oil pipe, it is only necessary to remove the sealing plate at either end of the oil cooler, and then find the corresponding cold oil pipe in the extraction groove and pull it out for removal. By setting the limiting cylinder, multiple cold oil pipes are not squeezed against each other, which not only facilitates disassembly and replacement, but the metal limiting cylinder separates the cold oil pipes, which also improves the cooling efficiency and is highly practical.

[0021] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0022] The present application discloses a cooling device for lubricating oil manufacturing. Figure 1-Figure 4 A cooling device for lubricating oil manufacturing includes an oil cooler tube body 1 and a cold oil pipe 5. Both ends of the oil cooler tube body 1 are fixed with connecting flange tubes 3 by bolts, and a sealing plate 4 is fixed on the connecting flange tube 3 by bolts. The parts fixed with bolts can be easily disassembled during subsequent maintenance. A pair of through pipes 2 are fixed on the oil cooler tube body 1; it also includes a limiting mechanism, which is installed inside the oil cooler tube body 1 and is used to limit and fix multiple cold oil pipes 5.

[0023] The limiting mechanism includes an embedded tube 6 embedded in the oil cooler tube body 1. The diameter of the embedded tube 6 is the same as the inner diameter of the oil cooler tube body 1. The embedded tube 6 is slidably connected to the oil cooler tube body 1. A removal groove 9 is provided at the end of the embedded tube 6. A removal groove 9 is provided between the embedded tube 6 and the limiting cylinder 7. The end of the cold oil pipe 5 is located in the removal groove 9. The length of the cold oil pipe 5 is equal to the length of the embedded tube 6. The limiting cylinder 7 is made of metal. The limiting cylinder 7 is slidably connected to the cold oil pipe 5. The end faces of the embedded tube 6 and the cold oil pipe 5 are connected to the sealing plate 4. The embedded tube 6, the limiting cylinder 7 and multiple cold oil pipes 5 are limited and fixed by the sealing plates 4 at both ends.

[0024] When replacing a damaged cooling oil pipe 5, one of the sealing plates 4 is disassembled with a wrench, and then multiple cooling oil pipes 5 can be observed. The one that needs to be removed can be removed by sliding it out. The operation is simple, convenient and quick. After removal, a new cooling oil pipe 5 can be installed, which improves practicality. By setting the embedded tube 6, the limiting cylinder 7, the limiting long hole 8 and the removal groove 9, when replacing the cooling oil pipe 5, it is only necessary to disassemble the sealing plate 4 at either end of the oil cooler, and then find the corresponding cooling oil pipe 5 in the removal groove, and pull it out for disassembly. By setting the limiting cylinder 7, multiple cooling oil pipes 5 are not squeezed against each other, which not only facilitates disassembly and replacement, but also the limiting cylinder 7 made of metal separates the cooling oil pipes 5, which also improves the cooling efficiency and has high practicality.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a limiting cylinder 7 is embedded on the inner side of the embedded tube 6, and a plurality of limiting long holes 8 are opened on the limiting cylinder 7. The limiting long holes 8 are obtained by injection molding, and the aperture size thereof is adapted to the type of cold oil pipe 5 used, and the limiting long holes 8 are embedded in the limiting long holes 8. The embedded tube 6 is made of metal, and the embedded tube 6 and the limiting cylinder 7 are slidably connected.

[0026] The implementation principle of a cooling device for lubricating oil manufacturing in the embodiment of the present application is as follows: when replacing a damaged cold oil pipe 5, one of the sealing plates 4 is disassembled using a wrench, and then multiple cold oil pipes 5 can be observed, and the one that needs to be removed can be removed by sliding it out. The operation is simple, convenient and quick, and a new cold oil pipe 5 can be installed after removal, which improves practicality. By setting an embedded tube 6, a limiting cylinder 7, a limiting long hole 8 and a removal groove 9, when replacing the cold oil pipe 5, it is only necessary to disassemble the sealing plate 4 at either end of the oil cooler, and then find the corresponding cold oil pipe 5 in the removal groove, and pull it out for disassembly. By setting the limiting cylinder 7, multiple cold oil pipes 5 are not squeezed against each other, which not only facilitates disassembly and replacement, but also the limiting cylinder 7 made of metal separates the cold oil pipes 5, which also improves cooling efficiency and has high practicality.
