[0019] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.
[0020] As Figures 1-3 shown, a precision mechanical lubrication system includes a fuel tank 1 and an oil pump 2. The oil pump 2 is arranged at the top of the fuel tank 1. The oil outlet end of the oil pump 2 is fixedly connected and communicated with a filter 3 through a pipeline. The filter 3 includes an outer shell 31. An outlet pipe 32 is arranged at the top of the outer shell 31. One end of the outlet pipe 32 is fixedly connected and communicated with a flow divider 4 through a pipeline. An inlet pipe 33 is arranged at the top of the side wall of the outer shell 31. A bottom shell 34 is slidably connected to the bottom of the outer shell 31. An annular partition 35 is arranged inside the outer shell 31. A driving component 36 for driving the bottom shell 34 to slide is arranged at the bottom of the annular partition 35. Filter paper layers 310 are arranged at both the top and the bottom of the outer shell 31.
[0021] According to the above structure, during use, the oil pump 2 pumps the lubricating oil inside the fuel tank 1 into the filter 3 for filtration. The filtered lubricating oil is distributed to corresponding components through the flow divider 4 for lubrication. During filtration, when the filter paper layer 310 on the upper part inside the outer shell 31 is severely blocked, the lubricating oil pumped into the inner part of the outer shell 31 pushes open the driving component 36, and the lubricating oil penetrates through the annular partition 35 and enters the bottom of the outer shell 31 for filtration. After the driving component 36 is pushed open, the driving component 36 pushes the bottom shell 34 to move. By observing the position of the bottom shell 34, it can be known whether a new filter 3 should be replaced, and the practicability is relatively high.
[0022] As Figure 3 and 4As shown in the figure, oil holes 351 are formed on the surface of the annular partition plate 35 and are equidistantly distributed around the axis of the annular partition plate 35. The driving assembly 36 includes an annular plate 361 disposed at the bottom end of the annular partition plate 35. The top end of the annular plate 361 is fixedly connected with conical heads 362 distributed at equal intervals. A plurality of conical heads 362 are respectively slidably connected inside a plurality of oil holes 351. The bottom end of the annular plate 361 is fixedly connected with a cylinder 363. A groove 364 is provided at the bottom end of the cylinder 363. A spring 365 is fixedly connected inside the groove 364. A support rod 366 is provided at the bottom of the cylinder 363. The top end of the support rod 366 is fixedly connected with connecting rods 367 distributed at equal intervals. One end of the connecting rod 367 is fixedly connected with the inner wall of the cylinder 363. The bottom end of the support rod 366 penetrates through the outer shell 31 and is fixedly connected with the bottom end of the inner wall of the bottom shell 34. An upper central pipe 37 is provided at the top inside the outer shell 31. A lower central pipe 38 is provided at the bottom inside the outer shell 31. Through holes are uniformly distributed on the surfaces of the upper central pipe 37 and the lower central pipe 38. A sleeve 381 is integrally connected to the top end of the lower central pipe 38. The cylinder 363 is slidably connected inside the sleeve 381. A one-way valve 312 is provided at the bottom end of the upper central pipe 37.
[0023] According to the above structure, when in use, the lubricating oil entering the inside of the outer shell 31 through the oil inlet pipe 33 is first filtered by the filter paper layer 310 at the top of the outer shell 31. When the filter paper layer 310 at the top is severely blocked by debris, it is difficult for the lubricating oil to enter the inside of the upper central pipe 37 through the through holes on the surface of the upper central pipe 37. At this time, the pressure at the top of the outer shell 31 increases, and the lubricating oil pushes the annular plate 361 downward through the oil holes 351. The cylinder 363 moves downward along with the annular plate 361 and compresses the spring 365. After the cylinder 363 descends, it drives the support rod 366 to push the bottom shell 34 to move. The annular plate 361 moves downward, and the conical heads 362 are separated from the inside of the oil holes 351, and the oil holes 351 are opened. The lubricating oil enters the bottom of the outer shell 31 and is filtered by the filter paper layer 310 at the bottom of the outer shell 31. The filtered lubricating oil flows upward through the lower central pipe 38, enters the inside of the upper central pipe 37 through the one-way valve 312, and finally is discharged along the oil outlet pipe 32.
[0024] As Figure 2 shown, a convex plate 341 is fixedly connected to the top end of the bottom shell 34. Scale lines 311 corresponding to the convex plate 341 are provided on the outer wall of the outer shell 31.
[0025] According to the above structure, the scale lines 311 play a marking role, facilitating the observation of the position of the bottom shell 34.
[0026] As Figure 3 and 4 shown, an oil seal 39 is provided in the middle of the bottom end of the outer shell 31. The support rod 366 penetrates through the oil seal 39.
[0027] According to the above structure, the oil seal 39 plays a sealing role to prevent the lubricating oil from leaking from the bottom end of the outer shell 31.
[0028] The working principle of the present utility model is as follows: during use, the oil pump 2 pumps the lubricating oil inside the fuel tank 1 into the filter 3 for filtration. The filtered lubricating oil is distributed to the corresponding components through the diverter 4 for lubrication. During filtration, when the filter paper layer 310 on the upper inner side of the outer shell 31 is severely blocked, the lubricating oil pumped into the inner part of the outer shell 31 will push open the driving component 36, and the lubricating oil passes through the annular partition 35 and enters the bottom of the outer shell 31 for filtration. After the driving component 36 is pushed open, the driving component 36 pushes the bottom shell 34 to move. By observing the position of the bottom shell 34, it can be known whether a new filter 3 should be replaced, which has high practicability. When in use, the lubricating oil entering the inner part of the outer shell 31 through the oil inlet pipe 33 is first filtered by the filter paper layer 310 on the top of the outer shell 31. When the top filter paper layer 310 is severely blocked by sundries, it is difficult for the lubricating oil to enter the inner part of the upper central pipe 37 through the through holes on the surface of the upper central pipe 37. At this time, the pressure at the top of the outer shell 31 increases, and the lubricating oil pushes the ring plate 361 downward through the oil hole 351. The cylinder 363 moves downward along with the ring plate 361 and squeezes the spring 365. After the cylinder 363 moves downward, it drives the support rod 366 to push the bottom shell 34 to move. The ring plate 361 moves downward, and the tapered head 362 separates from the inner part of the oil hole 351, and the oil hole 351 is opened. The lubricating oil enters the bottom of the outer shell 31 and is filtered by the filter paper layer 310 at the bottom of the outer shell 31. The filtered lubricating oil flows upward through the lower central pipe 38, enters the inner part of the upper central pipe 37 through the one-way valve 312, and finally is discharged along the oil outlet pipe 32.
[0029] The above description is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
