Description

Technical Field

[0001] This utility model relates to the field of lubricating oil circulation technology, and in particular to an automatic lubrication system for external circulation of gear oil. Background Technology

[0002] Current lubrication devices on the market store oil in an oil reservoir, and deliver the lubricating oil to various distributors via an electric oil pump. The distributors then control the distribution of the lubricating oil to each point using the same pressure or volume. After flowing through each point, the lubricating oil drips to a centralized collection point, where it is manually disposed of, resulting in excessively high recycling costs.

[0003] This lubrication method has several drawbacks: 1. It cannot recycle and reuse lubricant, and even if it can be recycled and processed, the cost is high. 2. It requires adding oil once a week or even every few days, resulting in excessively high lubrication costs. 3. Due to considerations of lubrication costs, the standard lubrication cycle is adjusted to 2000-4000 cycles, which leads to joints not being lubricated in time and easily causing wear and tear on the equipment joints.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] To better understand the purpose, function, and specific design scheme of this utility model, the fully automatic opening and pressing machine of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] like Figures 1-3 As shown, the gear oil external circulation automatic lubrication system includes an external circulation box 4, which contains an oil return chamber 11, a filter chamber, and an oil outlet chamber 17. The oil return chamber 11 is provided with an oil return pipe 2, a drain outlet 7, and a first through hole 12 connecting to the filter chamber. A drain valve is provided at the drain outlet 7. A first filter 14 is installed at the first through hole 12. The filter chamber is provided with a second through hole connecting to the oil outlet chamber 17. The second through hole is lower than the first through hole 12. A second filter 15 is installed in the second through hole. A lubricating oil pump assembly 8 is installed in the oil outlet chamber 17.

[0031] During operation, the inlet of the oil return pipe 2 is connected to the unified lubricating oil recovery tray of the main unit, and the outlet of the oil return pipe 2 is connected to the oil return chamber 11. The lubricating oil in the unified recovery tray enters the oil return chamber 11 through the oil return pipe 2. The recovered lubricating oil is layered in the oil return chamber 11, with denser water settling at the bottom and less dense lubricating oil floating on top. The water at the bottom can be manually drained through the drain valve. When the upper layer of lubricating oil reaches the height of the first through hole 12, it flows into the first filter 14. After being filtered by the first filter 14, the lubricating oil flows into the filter chamber. When the lubricating oil level in the filter chamber reaches the height of the second through hole, the lubricating oil in the filter chamber passes through the second filter 15. After filtration, the lubricating oil enters the oil outlet chamber 17 through the second through hole. Finally, the lubricating oil in the oil outlet chamber 17 is pumped to the mechanical lubrication distribution of the main machine by the lubricating oil pump assembly 8. Oil-water separation can be performed through the return oil chamber 11. By setting up the filter chamber, the first filter 14 and the second filter 15, the separated lubricating oil can be filtered, so that the lubricating oil can be easily recycled and reused, reducing the cost of lubricating oil in production equipment and reducing the labor cost of lubrication and maintenance of equipment in production. The lubrication cycle can be adjusted to 100-200 cycles per lubrication, which can give the joints of the equipment a better lubrication cycle. At the same time, it can also wash away the powder generated by the break-in and friction during the operation of the equipment, reducing the wear rate of the equipment.

[0032] Furthermore, in this embodiment, the shape of the external circulation box 4 is not limited and can be circular, rectangular or other shapes. For example, it is set to a rectangle in this application to adapt to the installation environment.

[0033] In this embodiment, the lubricating oil pump assembly 8 is one of a piston pump, plunger pump, PLC-controlled lubricating pump, or digital display time-adjustable lubricating pump. In this embodiment, a digital display time-adjustable lubricating pump is used. The lubricating oil pump assembly 8 has a built-in time-adjustable controller to control the working time and intermittent time of the oil pump. The lubricating oil pump assembly is also equipped with a level switch and a pressure switch. When the oil level is insufficient, the oil pump controller will emit a buzzer alarm, and the alarm can also be fed back to the host system.

[0034] In some embodiments, the external circulation box 4 is configured as a transparent box. The exemplary external circulation box 4 can be integrally formed of transparent acrylic material so that the internal liquid level can be seen. For example, when the water level at the bottom of the oil return chamber 11 is high, the drain valve can be opened manually to drain the water. When the lubricating fluid level in the oil outlet chamber 17 is high, the lubricating oil pump can be turned on to drain the oil.

[0035] In some embodiments, the external circulation tank 4 is an opaque tank, and level gauges 9 are installed in both the oil return chamber 11 and the oil outlet chamber 17. For example, the level gauges 9 are side-mounted level gauges 9. Lower mounting holes 18 and upper mounting holes 19 are provided on the side walls of the oil return chamber 11 and the oil outlet chamber 17 of the external circulation tank 4, so that the water level at the bottom of the oil return chamber 11 can be viewed through the level gauge 9 on the left side, thereby facilitating drainage by manual means. The level of lubricating oil in the oil outlet chamber 17 can be viewed through the level gauge 9 on the right side.

[0036] In some embodiments, the first filter 14 and the second filter 15 are both installed in the filter chamber and are staggered. For example, the outer circulation box 4 is divided into an oil return chamber 11, a filter chamber and an oil outlet chamber 17 by a first partition 13 and a second partition 16. The filter chamber is located between the first partition 13 and the second partition 16. A first through hole 12 is provided on the upper front side of the first partition 13. The first filter 14 is detachably installed on the right side of the first through hole 12. A second through hole is provided on the lower rear side of the second partition 16. The second filter 15 is detachably installed on the left side of the second through hole.

[0037] In the above embodiment, the lubricating oil enters the first filter 14 after passing through the first through hole 12. After being filtered by the first filter 14, the lubricating oil enters the second filter 15. The lubricating oil in the second filter 15 flows through the second through hole and enters the oil outlet chamber 17. By setting a height difference, under normal working conditions, the height of the lubricating oil in the filter chamber generally does not reach the height of the first filter 14. Therefore, the lubricating oil entering the first filter 14 can be filtered smoothly. By staggering the arrangement, on the one hand, the space utilization rate can be improved, making the equipment more compact. On the other hand, the lubricating oil does not flow directly into the second filter 15 after being filtered by the first filter 14. There is a process of flowing from the front to the back in the filter chamber, which helps to settle some waste debris.

[0038] In one embodiment, the first filter 14 and the second filter 15 have the same structure, both including a hydraulic oil filter element. The oil inlet end of the hydraulic oil filter element is fixed with a connector 22 by bolts. A connecting ring matching the connector 22 is provided at the first through hole 12 and the second through hole. The connecting ring and the connector 22 are connected by threads.

[0039] In some embodiments, an opening is provided at the top of the external circulation box 4, and a mounting plate 1 is provided at the opening. The lubricating oil pump assembly 8 is fixed on the mounting plate 1. The mounting plate 1 is detachably provided at the top of the external circulation box 4, thereby enabling convenient maintenance of the interior of the external circulation box 4.

[0040] In some embodiments, the top of the external circulation box 4 is provided with a top ear plate 3, and the bottom of both ends of the external circulation box 4 are provided with bottom connectors 5. Bottom ear plates 6 are provided on the bottom connectors 5, and waist holes are provided on the top ear plate 3 and the bottom ear plate 6.

[0041] The main unit is fixedly installed through the aforementioned waist holes.

[0042] like Figures 3-5 As shown, in some embodiments, the gear oil external circulation automatic lubrication system includes an external circulation box 4, which is provided with an oil return chamber 11, a filter chamber, and an oil outlet chamber 17. The oil return chamber 11 is provided with an oil return pipe 2, a bottom suction pump 21, and a first through hole 12 connecting to the filter chamber. A first filter 14 is installed at the first through hole 12. The filter chamber is provided with a second through hole connecting to the oil outlet chamber 17. The second through hole is lower than the first through hole 12. A second filter 15 is installed in the second through hole. A lubricating oil pump assembly is installed in the oil outlet chamber 17.

[0043] During operation, the oil inlet of the oil return pipe 2 is connected to the unified lubricating oil recovery tray of the main unit, and the oil outlet of the oil return pipe 2 is connected to the oil return chamber 11. The lubricating oil in the unified recovery tray enters the oil return chamber 11 through the oil return pipe 2. The recovered lubricating oil is layered in the oil return chamber 11, with the denser water settling at the bottom and the less dense lubricating oil floating at the top. When the water level in the oil return chamber 11 exceeds the suction port of the bottom suction pump 21, the bottom suction pump 21 is automatically drained. When the lubricating oil in the upper layer reaches the height of the first through hole 12, it flows into the first filter 14. After being filtered by the first filter 14, the lubricating oil flows into the filter chamber. When the lubricating oil level in the filter chamber reaches the height of the second through hole, the lubricating oil in the filter chamber... After being filtered by the second filter 15, the lubricating oil enters the oil outlet chamber 17 through the second through hole. Finally, the lubricating oil in the oil outlet chamber 17 is pumped to the mechanical lubrication distribution of the main machine by the lubricating oil pump assembly 8. Oil-water separation can be performed through the return oil chamber 11. By setting up the filter chamber, the first filter 14 and the second filter 15, the separated lubricating oil can be filtered, so that the lubricating oil can be easily recycled and reused, reducing the cost of lubricating oil in production equipment and reducing the labor cost of lubrication and maintenance of equipment in production. The lubrication cycle can be adjusted to 100-200 cycles per lubrication, which can give the joints of the equipment a better lubrication cycle. At the same time, it can also wash away the powder generated by the break-in and friction during the operation of the equipment, reducing the wear rate of the equipment.

[0044] In one possible implementation, if the external circulation box 4 is a metal box, then an insulating box 20 with a top opening is provided in the oil return chamber 11 to house the bottom suction pump 21, and the oil return pipe 2 extends into the insulating box 20. If the external circulation box 4 is a non-metallic box, then the bottom suction pump 21 is directly installed in the oil return chamber 11, and the positive and negative contacts of the bottom suction pump 21 are located above the suction port, and the positive and negative contacts are open.

[0045] In some embodiments, the external circulation box 4 is configured as a transparent box. The exemplary external circulation box 4 can be integrally formed of transparent acrylic material so that the internal liquid level can be seen. For example, when the water level at the bottom of the oil return chamber 11 is high, the drain valve can be opened manually to drain the water. When the lubricating fluid level in the oil outlet chamber 17 is high, the lubricating oil pump can be turned on to drain the oil.

[0046] In some embodiments, the external circulation tank 4 is an opaque tank, and level gauges 9 are installed in both the oil return chamber 11 and the oil outlet chamber 17. For example, the level gauges 9 are side-mounted level gauges 9. Lower mounting holes 18 and upper mounting holes 19 are provided on the side walls of the oil return chamber 11 and the oil outlet chamber 17 of the external circulation tank 4, so that the water level at the bottom of the oil return chamber 11 can be viewed through the level gauge 9 on the left side, thereby facilitating drainage by manual means. The level of lubricating oil in the oil outlet chamber 17 can be viewed through the level gauge 9 on the right side.

[0047] In some embodiments, the first filter 14 and the second filter 15 are both installed in the filter chamber and are staggered. For example, the outer circulation box 4 is divided into an oil return chamber 11, a filter chamber and an oil outlet chamber 17 by a first partition 13 and a second partition 16. The filter chamber is located between the first partition 13 and the second partition 16. A first through hole 12 is provided on the upper front side of the first partition 13. The first filter 14 is detachably installed on the right side of the first through hole 12. A second through hole is provided on the lower rear side of the second partition 16. The second filter 15 is detachably installed on the left side of the second through hole.

[0048] When the water level in the lower layer of the return oil chamber 11 does not exceed the suction port, the positive and negative contacts of the bottom suction pump 21 are only in contact with the lubricating oil. Since the lubricating oil cannot conduct electricity, the switch of the bottom suction pump 21 is in the normally open state, and the bottom suction pump 21 does not work. When the water level in the lower layer of the return oil chamber 11 exceeds the suction port, the positive and negative contacts of the bottom suction pump 21 are in contact with the water. Since the water can conduct electricity, the switch of the bottom suction pump 21 is in the closed state, and the bottom suction pump 21 works to automatically discharge the lower layer of water.

[0049] Furthermore, in this embodiment, the drain pipe 10 of the bottom suction pump 21 extends out from the top mounting plate 1, and the bottom suction pump 21 pumps out the bottom water in the oil return chamber 11 and discharges it through the drain pipe 10.

[0050] In one possible implementation, the lower part of the return oil pipe 2 is 20-30mm above the bottom of the return oil chamber 11, so as to ensure that water can be immediately sensed and discharged in time after returning to the return oil chamber 11.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
