Description

Technical Field

[0001] The present invention relates to the technical field of engine lubrication systems, and specifically, to a device for detecting metal particles in an engine lubrication system. Background Art

[0002] An engine is a high-speed rotating machine. During operation, the various components inside the engine will continuously and frequently experience surface friction. This friction generates a large amount of heat, which not only increases the power loss of the engine but also damages the surfaces of high-temperature components, affecting the normal operation of the engine and even damaging the machine parts. The lubrication system is responsible for generating an oil film on the contact surfaces of each component, playing a good lubricating and buffering role. However, after the engine runs for a long time, it is still inevitable that some metal particles will be generated due to the friction of each component. These metal particles enter the oil circuit of the lubrication system and enter the circulation. If a large amount of metal particles accumulate, it may cause irreparable damage to the engine. Therefore, a metal particle detection device has emerged. It can detect the content of metal particles in the oil circuit of the lubrication system, playing a role in early warning and timely maintenance of the lubrication system. However, there is still a problem with traditional metal particle detection devices, which is that they can only monitor but cannot remove the metal particles in the lubrication system.

While monitoring the content of metal particles in the engine lubricating oil system, it plays a role in separating the metal particles in the lubricating oil, and solves the problem that the traditional metal particle detection device in the related technology can only monitor but cannot remove the metal particles in the lubricating system.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present invention.

[0046] As Figures 1 to 5 shown, a metal particle detection device for an engine lubrication system includes

[0047] a metal scanning detector 1,

[0048] a first oil pipe joint 2, which is arranged above the metal scanning detector 1, and the first oil pipe joint 2 is used to connect the metal scanning detector 1 with the return oil pipe of the engine lubricating oil system,

[0049] a metal particle precipitation block 3, which is arranged below the metal scanning detector 1, the metal particle precipitation block 3 has a vertical oil path 4, the vertical oil path 4 is communicated with the metal scanning detector 1, the axis of the vertical oil path 4 is perpendicular to the ground, the metal particle precipitation block 3 also has a connection hole 5, the axis of the connection hole 5 is perpendicular to the axis of the vertical oil path 4, and the connection hole 5 is located at one end of the vertical oil path 4 close to the metal scanning detector 1,

[0050] a second oil pipe joint 6, which is sleeved in the connection hole 5, and the second oil pipe joint 6 is used to connect the metal particle precipitation block 3 with the supply oil pipe of the engine lubricating oil system,

[0051] a filter head 7, which is arranged at one end of the second oil pipe joint 6 located in the connection hole 5, and the filter head 7 is inserted into the vertical oil path 4.

[0052] In this embodiment, the return oil pipe of the engine lubricating oil system is connected to the first oil pipe joint 2, and the supply oil pipe of the engine lubricating oil system is connected to the second oil pipe joint 6. After the lubricating oil circulates inside the engine, it reaches the metal scanning detector 1 through the return oil pipe connected to the first oil pipe joint 2. After the metal scanning detector 1 scans and records the metal content in the lubricating oil, the lubricating oil reaches the vertical oil passage 4 of the metal particle sedimentation block 3. Then the lubricating oil can pass through the filter head 7 and return to the engine interior through the engine lubricating system supply oil pipe connected to the second oil pipe joint 6 to start the next cycle. However, the metal particles in the lubricating oil cannot pass through the filter head 7, and the metal particles will precipitate at the bottom of the vertical oil passage 4. The length of the filter head 7 extending from the connection hole 5 into the vertical oil passage 4 is as short as possible, so that as few metal particles as possible fall on the side wall of the filter head 7, and the metal particles can fall to the bottom of the vertical oil passage 4 as much as possible. In this way, the metal scanning detector 1 can scan and record the content of metal particles in each lubricating oil circulation process. When the content of metal particles accumulates to a certain value, maintenance personnel can perform maintenance on our engine lubricating system in advance. Moreover, the metal particles in the lubricating oil will also be filtered out by the filter head 7 and precipitate at the bottom of the vertical oil passage 4 and will no longer enter the engine, solving the problem that the traditional metal particle detection device in the related technology can only monitor but cannot remove the metal particles in the lubricating system.

[0053] Further, it further includes

[0054] a magnetic member 8, which is arranged at one end of the vertical oil passage 4 far away from the metal scanning detector 1.

[0055] In this embodiment, there is a magnetic member 8 at the bottom of the vertical oil passage 4. The magnetic member 8 can assist gravity to attract the metal particles intercepted by the filter head 7 in the vertical oil pipe 4 to the bottom of the vertical oil passage 4 for the first time, accelerating the precipitation of the metal particles.

[0056] Further, the vertical oil passage 4 penetrates through the metal particle sedimentation block 3, and one end of the vertical oil passage 4 far away from the metal scanning detector 1 has a threaded hole 9. The magnetic member 8 includes

[0057] a threaded rod 10, one end of which is sleeved in the threaded hole 9,

[0058] a plug 11, which is arranged at the other end of the threaded rod 10, and the plug 11 abuts against the metal particle sedimentation block 3.

[0059] In this embodiment, when the number of metal particles recorded by the metal scanning detector 1 reaches a certain value and the engine needs to be maintained, after the engine stops, the metal particle detection device of the engine lubrication system can be cleaned and maintained by the way. After removing the plug 11 and the threaded rod 10 from the threaded hole 9 on the vertical oil passage 4, most of the metal particles can be taken out of the vertical oil passage 4 and then cleaned. Then, after cleaning the remaining metal particles in the vertical oil passage 4, the plug 11 and the threaded rod 10 are reinstalled into the threaded hole 9 on the vertical oil passage 4, and the cleaning and maintenance of the metal particle detection device of the engine lubrication system can be completed.

[0060] Further, one end of the plug 11 abuts against the metal particle sedimentation block 3 and has a sealing ring groove 12, and a sealing ring 13 is also arranged in the sealing ring groove 12.

[0061] In this embodiment, when the plug 11 is installed on the threaded hole 9 of the vertical oil passage 4, a sealing ring 13 is also installed in the sealing ring groove 12 of the plug 11. As the plug 11 and the threaded rod 10 rotate, the threaded rod 10 gradually enters the threaded hole 9. After the sealing ring 13 abuts against the metal particle sedimentation block 3, as the plug 11 and the threaded rod 10 continue to rotate until the plug 11 completely abuts against the metal particle sedimentation block 3, at this time the sealing ring 13 is compressed, which plays a good sealing role for the lubricating oil in the vertical oil passage 4.

[0062] Further, it also includes

[0063] a bracket 14, the metal particle sedimentation block 3 is arranged on the bracket 14,

[0064] a recovery bin 15, which is arranged on the bracket 14,

[0065] a bell mouth 16, which is arranged above the recovery bin 15, and the bell mouth 16 is located below the magnetic part 8.

[0066] In this embodiment, when the engine is shut down for maintenance and the metal particle detection device of the engine lubrication system is cleaned and maintained, after the magnetic part 8 is removed from the vertical oil passage 4, the remaining lubricating oil and some metal particles in the vertical oil passage 4 will fall freely and be collected by the bell mouth 16 on the recovery bin 15 and enter the recovery bin 15. This can avoid the problem of lubricating oil splashing and causing sanitation problems, and at the same time, it can realize the collection and recovery of the remaining lubricating oil and metal particles in the oil passage.

[0067] Further, it also includes

[0068] a filter screen 17, which is arranged at one end of the bell mouth 16 close to the recovery bin 15, and the axis of the holes of the filter screen 17 is parallel to the axis of the bell mouth 16.

[0069] In this embodiment, when the engine is shut down for maintenance and the metal particle detection device of the engine lubrication system is cleaned and maintained, after the magnetic part 8 is removed from the vertical oil passage 4, the residual lubricating oil and some metal particles in the vertical oil passage 4 will fall freely and be collected by the flared opening 16 on the recovery bin 15. The lubricating oil will enter the recovery bin through the holes in the filter screen 17, while the metal particles will be separately filtered out by the filter screen 17. After the magnetic part 8 is reinstalled into the vertical oil passage 4, the metal particles on the filter screen 17 can also be separately recovered, realizing the separation and recovery of the residual lubricating oil and metal particles in the oil passage.

[0070] Further, it also includes

[0071] A recovery pipe 18, arranged at the bottom on one side of the recovery bin 15,

[0072] A deflector plate 19, arranged at the bottom of the recovery bin 15. One end of the deflector plate 19 close to the recovery pipe 18 is lower than the end of the deflector plate 19 far from the recovery pipe 18.

[0073] A valve 20, arranged on the recovery pipe 18.

[0074] In this embodiment, usually the valve 20 on the recovery pipe 18 is closed. When there is a large amount of lubricating oil collected in the recovery bin 15, the valve 20 can be opened to release the lubricating oil in the recovery bin 15 through the recovery pipe 18 for other uses and secondary utilization. At the same time, the deflector plate 19 makes the lubricating oil in the recovery bin 15 flow as much as possible towards the end of the recovery bin 15 where the recovery pipe 18 is located. When the valve 20 is opened, as much lubricating oil in the recovery bin 15 as possible can be released.

[0075] Further, it also includes

[0076] A lid 21, arranged above the flared opening 16.

[0077] In this embodiment, when there is no need to clean and maintain the metal particle detection device of the engine lubrication system and the magnetic part 8 is not removed from the vertical oil passage 4, the lid 21 covers the entire flared opening 16, preventing dust in the environment from falling into the flared opening 16, causing environmental problems or even polluting the flared opening 16 and the lubricating oil in the recovery bin 15. When it is necessary to clean and maintain the metal particle detection device of the engine lubrication system, first open the lid 21 to expose the flared opening 16 below the lid 21, and then remove the magnetic part 8 from the vertical oil passage 4 to clean and maintain the metal particle detection device of the engine lubrication system.

[0078] Further, the lid 21 includes

[0079] A rotating shaft 22, arranged on the flared opening 16. The axis of the rotating shaft 22 is parallel to but not concentric with the axis of the flared opening 16.

[0080] The cover plate 23 is rotatably arranged on the rotating shaft 22.

[0081] The handle 24 is arranged on the cover plate 23.

[0082] In this embodiment, when it is necessary to clean and maintain the metal particle detection device for the engine lubrication system, the handle 24 on the cover plate 23 can be held to rotate the cover plate 23 around the rotating shaft 22 on the bell mouth 16, move the cover plate 23 away from directly above the bell mouth 16 to expose the bell mouth 16, and then remove the magnetic part 8 from the vertical oil passage 4 to clean and maintain the metal particle detection device for the engine lubrication system.

[0083] Furthermore, it further includes

[0084] The sliding track 25 is arranged on the top of the bracket 14. One end of the sliding track 25 is located above the bell mouth 16, and the other end of the sliding track 25 is away from the bell mouth 16.

[0085] There are several rollers 26 rotatably arranged on the outer side wall of the metal particle precipitation block 3, and the rollers 26 abut against the sliding track 25.

[0086] In this embodiment, when it is necessary to clean and maintain the metal particle detection device for the engine lubrication system, the metal particle precipitation block 3 is pushed along the sliding track 25 so that the metal particle precipitation block 3 is located directly above the bell mouth 16. The magnetic part 8 is removed from the vertical oil passage 4 to clean and maintain the metal particle detection device for the engine lubrication system. The residual lubricating oil and some metal particles in the vertical oil passage 4 will fall freely and be collected by the bell mouth 16 on the recovery bin 15. The lubricating oil will enter the recovery bin 15 through the holes in the filter net 17, while the metal particles are separately filtered out by the filter net 17. After the magnetic part 8 is reinstalled into the vertical oil passage 4, the metal particle precipitation block 3 is pushed along the sliding track 25 to the end away from the bell mouth 16 to expose the bell mouth 16 below the metal particle precipitation block 3, so as to facilitate the collection and recovery of the metal particles on the filter net 17 in the bell mouth 16.

[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
