Description

Technical Field

[0001] The present application relates to the field of engine lubrication systems, and in particular to a lubrication system with rapid pressure buildup in a main oil channel. Background Art

[0002] When a large-cylinder engine is cold-started, if the engine's moving parts operate in a state of lack of oil or insufficient oil, the friction loss of each moving part will increase, and the temperature will rise sharply, causing irreparable losses such as lavalier seizure. Therefore, before the engine is cold-started, the large-cylinder engine must be pre-lubricated. One of the existing practices is to provide an independent pre-supply lubricating oil pump. Before the engine is started, the pre-supply oil pump is used to fill the engine oil system with oil to complete the pre-lubrication of the entire engine. When the engine is shut down, the oil in the oil system, including the oil in high-position parts such as the oil cooler, oil filter, and pipelines, will flow back to the engine's oil pan under the action of gravity.

[0003] The engine's lubrication system often uses a two-stage filter to filter impurities in the oil. The first stage is a coarse filter that filters larger impurities in the oil; the second stage is a paper fine filter that filters smaller impurities in the oil. Structurally, the first-stage coarse filter is generally placed before the oil pump, and the second-stage paper fine filter is placed after the oil pump. This arrangement has the problem that the first-stage coarse filter cannot filter out smaller metal particles in the oil, such as iron filings produced by gear pitting or particles produced by initial wear of other moving parts. These particles enter the oil pump. The particle diameter is much larger than the clearance between the inner and outer rotors of the oil pump, causing pits to form when the metal particles are squeezed out of the inner and outer rotors of the oil pump. In severe cases, the oil pump may become stuck or even damaged, further damaging the engine. For example, the lubrication system and engine disclosed in Chinese application number 202220567004.8 can use the same functional hole to complete the installation, disassembly, cleaning and replacement of the primary filter and the secondary filter. However, when replacing the filter, the entire filter must be replaced. Generally, the internal filter component of the filter plays the role of filtering the engine oil. Therefore, replacing the entire filter will increase the cost of subsequent replacement and maintenance. Summary of the Invention

[0004] In order to overcome the existing deficiencies, an embodiment of the present application provides a lubrication system for quickly building up pressure in the main oil channel, which can solve the problem that the above-mentioned filter mainly relies on the internal filter component to filter the engine oil, so replacing the entire filter will increase the cost of subsequent replacement and maintenance.

[0005] The technical solution adopted by the embodiment of the present application to solve its technical problem is: a lubrication system for quickly building up pressure in the main oil channel, including a filter.

[0006] The filter includes a mounting seat, on which several filter cartridges are detachably provided, and each filter cartridge is provided with an outwardly protruding convex groove on the opposite side of the side wall, and a movable limiting member is provided inside the convex groove. A filter element is provided inside the filter cartridge, and the movable limiting member limits the filter element to achieve a detachable connection between the filter element and the filter cartridge. Each filter cartridge can be provided with a connecting pipe, and adjacent filter cartridges are connected to each other, and the connecting pipe is connected to the oil channel of the engine.

[0007] In a specific embodiment, the filter element comprises an inverted trapezoidal filter plate, and both ends of the top of the inverted trapezoidal filter plate are fixedly connected with semicircular clamping plates, and the semicircular clamping plates are in cooperative contact with the movable limiting member.

[0008] In a specific embodiment, the movable limiting member has a telescopic spring connected to the interior of the convex groove, and the other end of the telescopic spring is connected to a semicircular protrusion, and the semicircular protrusion and the semicircular clamping plate cooperate with each other to be detachably clamped.

[0009] In a specific embodiment, a handle is installed on the semicircular card plate.

[0010] In a specific embodiment, the filter cartridge is located above the filter element and is connected to an oil inlet pipe. The oil inlet pipe is detachably connected to a connecting piece, and the other end of the connecting piece is rotatably connected to the connecting pipe.

[0011] In a specific embodiment, the connecting member includes a joint pipe, one end of the joint pipe is detachably connected to the oil inlet pipe, and the other end of the joint pipe is rotatably connected to the connecting pipe.

[0012] In a specific embodiment, a nut is fixedly connected to the outer side of the joint pipe.

[0013] In a specific embodiment, a first internal thread is provided inside one end of the joint pipe, and a first external thread matching the first internal thread is provided on the outer wall of the oil inlet pipe.

[0014] The advantages of the embodiments of the present application are:

[0015] By setting a movable limiter, the filter element can be detachably connected to the filter cartridge.

DETAILED DESCRIPTION

[0022] The technical solution in the embodiment of the present application is to solve the problem that the above-mentioned filter mainly plays the role of internal filter assembly in filtering the oil, so replacing the entire filter will increase the cost of subsequent replacement and maintenance. The overall idea is as follows:

[0023] See also Figure 1-Figure 5 , a lubrication system for quickly building up pressure in a main oil channel, including a filter.

[0024] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The filter includes a mounting base 3. Specifically, a connecting base 4 is installed on the mounting base 3. The filter cartridge 2 is detachably connected to the connecting base 4. 2-3 filter cartridges 2 can be provided. The filtering effects of the 2-3 inverted trapezoidal filter plates 51 can be arranged in descending order of coarse to fine. The mounting base 3 is installed on the engine 1. Several filter cartridges 2 are detachably provided on the mounting base 3. The opposite sides of the side walls of each filter cartridge 2 are provided with outwardly protruding convex grooves 21. The interior of the convex grooves 21 is provided with a movable limiter 9. A filter element 5 is provided inside the filter cartridge 2. The movable limiter 9 limits the position of the filter element 5 to achieve detachable connection between the filter element 5 and the filter cartridge 2. Each filter cartridge 2 can be provided with a connecting pipe 6, and adjacent filter cartridges 2 are connected to each other. The connecting pipe 6 is connected to the oil channel of the engine 1. When the filter has a poor filtering effect on the oil after use at one end, the filter cartridge 2 is removed from the mounting base 3, and the filter element 5 is lifted up and removed from the interior of the filter cartridge 2. The filter element 5 inside can then be replaced. By setting the movable limit member 9, the filter element 5 can be detachably connected to the filter cartridge 2. In this way, when replacing the filter element 5, only the filter element 5 needs to be replaced, which reduces the subsequent maintenance and replacement costs of the engine 1, and further reduces the costs incurred by consumers in subsequent maintenance.

[0025] In this embodiment, the oil flow direction is: oil pan → oil pump → gear chamber oil channel (embedded check valve) → distributor oil channel → oil cooler → oil filter → engine body main oil channel → each gear main journal.

[0026] An embedded check valve is designed at the oil pump outlet to prevent the oil in the oil cooler, oil filter and channel from flowing back into the oil pan, allowing the oil to continue to remain in the cavity, effectively shortening the time required for the oil to fill the inner cavity at the next start, thereby achieving the purpose of quickly building up pressure before starting the engine 1, reducing the contact friction between the crankshaft and the bearing, and extending the service life of the engine 1.

[0027] In a specific embodiment, the filter element 5 includes an inverted trapezoidal filter plate 51, with semicircular retaining plates 52 fixedly connected to each end of the top of the inverted trapezoidal filter plate 51. The semicircular retaining plates 52 engage with a movable stopper 9. A telescopic spring 92 is connected to the interior of the protruding groove 21 of the movable stopper 9. The other end of the telescopic spring 92 is connected to a semicircular protrusion 91. The semicircular protrusion 91 engages with the semicircular retaining plate 52 for removable engagement. A handle 53 is mounted on the semicircular retaining plate 52. To install the inverted trapezoidal filter plate 51, grasp the handle 53, place the inverted trapezoidal filter plate 51 within the filter cartridge 2, and then move it downward. When the semicircular retaining plate 52 contacts the semicircular protrusion 91, the semicircular protrusion 91 is squeezed into the protruding groove 21. As the filter plate 51 continues to move downward, the semicircular retaining plate 52 is locked outside the semicircular protrusion 91. At this point, the telescopic spring 92 acts to lock the semicircular retaining plate 52 in place, preventing it from moving downward.

[0028] In a specific embodiment, the filter cartridge 2 is located above the filter element 5 and is connected to an oil inlet pipe 7. A connector 8 is detachably connected to the oil inlet pipe 7, and the other end of the connector 8 is rotatably connected to the connecting pipe 6. The connector 8 includes a joint pipe 81, one end of which is detachably connected to the oil inlet pipe 7, and the other end of the joint pipe 81 is rotatably connected to the connecting pipe 6. A nut 82 is fixedly connected to the outer side of the joint pipe 81. A first internal thread is provided inside one end of the joint pipe 81, and a first external thread that matches the first internal thread is provided on the outer wall of the oil inlet pipe 7. Before removing the filter cartridge 2 from the mounting seat 3, the nut 82 is rotated so that the joint pipe 81 is unscrewed from the filter cartridge 2, and the filter cartridge 2 can be removed. Adjacent filter cartridges 2 are also connected through the connecting pipe 6, and their connection relationship is also connected through the connector 8.

[0029] When using this application:

[0030] By setting the movable limit member 9, the filter element 5 can be detachably connected to the filter cartridge 2. In this way, when replacing the filter element 5, only the filter element 5 needs to be replaced, which reduces the subsequent maintenance and replacement costs of the engine 1, and further reduces the costs incurred by consumers in subsequent maintenance.

[0031] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
