Description

Technical Field

[0001] The utility model relates to the technical field of engine oil compensation, and specifically to an engine oil compensation circulation device for high-power internal combustion engines. Background Art

[0002] The engine oil compensation circulation device for high-power internal combustion engines is an important system used to maintain the normal operation of the engine and extend its service life. Its function is to keep an appropriate amount of engine oil inside the engine, supplement the engine oil lost due to combustion, evaporation or leakage, and ensure that all components of the engine are fully lubricated. During operation, the oil level sensor continuously monitors the engine oil level. When the oil level is lower than the set value, the control unit activates the oil pump. The oil pump extracts engine oil from the storage tank and delivers it into the engine. The system automatically adjusts the supplementary amount to maintain the optimal oil level.

[0003] Before the engine oil is transmitted to the engine, it will pass through a filtration system. The filtration system filters the engine oil input into the engine. The filtration system includes an oil pump, an oil filter, a bypass valve, a pressure regulating valve, an oil cooler, etc. The operation process is as follows: Oil suction: The oil pump sucks engine oil from the oil pan, and the engine oil passes through the filter screen for preliminary filtration; Pressure generation: The oil pump pressurizes the engine oil, and the pressure regulating valve controls the system pressure within the set range; Main filtration process: The pressurized engine oil enters the oil filter, and the engine oil passes through the filter element to remove fine impurities and metal particles; Bypass protection: If the filter is blocked, the bypass valve opens, and the unfiltered engine oil bypasses the filter and directly enters the system to ensure uninterrupted lubrication; Cooling process: The filtered engine oil enters the oil cooler and exchanges heat with the cooling medium (such as water or air) to reduce the temperature; Distribution and lubrication: The cooled engine oil is distributed to each component of the engine through the oil passage to lubricate key parts such as bearings, pistons, and camshafts; Return process: After the lubrication is completed, the engine oil flows back to the oil pan under the action of gravity to prepare for the next cycle.

[0004] During the above filtration process, when the filter is blocked, the bypass valve opens, and the unfiltered engine oil directly enters the engine. Although it can maintain the uninterrupted transmission of engine oil, the impurities in the unfiltered engine oil will cause certain damage to the engine.

[0005] Therefore, in view of the above existing problems, this technical solution proposes an engine oil compensation circulation device for high-power internal combustion engines. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an engine oil compensation circulation device for high-power internal combustion engines to solve the problems raised in the above background art.

[0007] To achieve the above object, the utility model provides the following technical solution: an oil compensation circulation device for a high-power internal combustion engine, comprising a housing. Inside the housing, a group of main rotary filter elements are arranged. The upper and lower ends of the main rotary filter elements are respectively communicated with a conical blanking port and a conical transmission port. The top of the conical blanking port is communicated with an oil inlet opened outside the top of the housing. Under the action of an oil pump, the oil is transmitted along the oil inlet into the conical blanking port. A bypass valve is arranged at the bottom inside the conical blanking port. The bottom end of the bypass valve is communicated with a straight transmission channel. The bottom end of the straight transmission channel is communicated with the conical transmission port. Mesh holes for the flow of oil are opened on the inclined surface of the conical blanking port. The oil entering the inside of the conical blanking port flows into the inside of the main rotary filter element along the mesh holes for filtration. After passing through multiple stages of filtration under the action of gravity, it is transferred into the conical transmission port. Then, under the action of the oil pump, it is transferred into the engine. At the same time, the upper and lower sides inside the straight transmission channel are provided with two parts, namely a standby filtration channel and a main filtration channel. The inner circumferential inner wall of the standby filtration channel is in sealed contact with the main rotary filter element. The inner circumferential side wall of the main filtration channel is in mesh communication with the main rotary filter element. A group of standby filtration elements are detachably installed at the lower side inside the standby filtration channel. The standby filtration elements are used for filtering the oil falling along the bypass valve. Then, under the action of gravity, it is transferred towards the conical transmission port along the main filtration channel. That is, when the main rotary filter element is blocked, the pressure received at the top of the bypass valve increases until the bypass valve opens. Then the oil directly falls along the bypass valve. At this time, it is filtered by the standby filtration elements and then directly transferred into the engine through the conical transmission port and the discharge hole. This method solves the problem that when the main rotary filter element is blocked, the oil is transferred into the engine without being filtered, and ensures the safe operation of the engine on the premise of not affecting the normal oil transmission.

[0008] Compared with the prior art, the beneficial effect of the utility model is that by arranging standby filtration elements under the bypass valve, while not affecting the normal oil transmission, when the main rotary filter element is blocked, the bypass valve automatically opens and filters the oil through the standby filtration elements, ensuring the normal filtered transmission of the oil towards the inside of the engine and improving the protection ability for the engine.

[0016] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0017] Please refer to Figures 1-3, An oil compensation circulation device for a high-power internal combustion engine, including a housing 10. Inside the housing 10, a set of main rotary filter elements 11 is provided. The upper and lower ends of the main rotary filter element 11 are respectively connected to a conical feeding port 13 and a conical transmission port 24. The top of the conical feeding port 13 is connected to an oil inlet 12 opened outside the top of the housing 10. Under the action of an oil pump, the oil is transmitted along the oil inlet 12 into the conical feeding port 13. A bypass valve 15 is provided at the bottom inside the conical feeding port 13. The bottom end of the bypass valve 15 is connected to a straight transmission channel 16. The bottom end of the straight transmission channel 16 is connected to the conical transmission port 24. Mesh holes 14 for oil flow are opened on the inclined surface of the conical feeding port 13. The oil entering the inside of the conical feeding port 13 flows into the inside of the main rotary filter element 11 along the mesh holes 14 for filtration. After passing through multiple stages of filtration under the action of gravity, it is transferred into the conical transmission port 24. Then, under the action of the oil pump, it is transferred into the engine. At the same time, the upper and lower sides inside the straight transmission channel 16 are provided with two parts, a standby filtration channel 17 and a main filtration channel 18. The circumferential inner wall inside the standby filtration channel 17 is in sealed contact with the main rotary filter element 11. The circumferential side wall inside the main filtration channel 18 is in mesh connection with the main rotary filter element 11. A set of standby filtration elements 19 is detachably installed at the lower side inside the standby filtration channel 17. The standby filtration elements 19 are used to filter the oil falling along the bypass valve 15. Then, under the action of gravity, it is transferred towards the conical transmission port 24 along the main filtration channel 18. That is, when the main rotary filter element 11 is blocked, the pressure received at the top of the bypass valve 15 increases until the bypass valve 15 opens. Then the oil directly falls along the bypass valve 15. At this time, it is filtered by the standby filtration elements 19 and then directly transferred into the engine through the conical transmission port 24 and the discharge hole 25. This method solves the problem that when the main rotary filter element 11 is blocked, the oil is transferred into the engine without being filtered, and ensures the safe operation of the engine on the premise of not affecting the normal oil transmission.

[0018] In the embodiment of the present invention, oil pumps are provided on the outer sides of the oil inlet 12 and the conical transmission port 24 respectively for driving the circulating flow of the oil. At the same time, a set of end covers 26 is detachably installed at the bottom end of the housing 10. A discharge hole 25 is opened in the middle inside the end cover 26. The top of the discharge hole 25 is connected to the bottom end of the conical transmission port 24. The outside of the oil inlet 12 is connected to an oil chassis, and the outside of the discharge hole 25 is connected to the engine through a pipe connection to control the transmission of the oil;

[0019] Regarding the start-stop operation of the bypass valve 15, its working principle is:

[0020] Normal state (closed):

[0021] When the system pressure is normal, the bypass valve remains closed

[0022] The engine oil flows downward along the mesh holes 14 and is filtered inside the main rotary filter element 11.

[0023] Starting state (on):

[0024] When the pressure at the top of the bypass valve 15 exceeds the set value, the bypass valve opens.

[0025] Part or all of the engine oil bypasses the mesh holes 14 and the main rotary filter element 11, flows along the lower side of the bypass valve 15, and is filtered and transmitted by the standby filter element 19.

[0026] In an example of the present invention, a set of external thread rings 21 are installed on the top of the standby filter element 19. Uniformly distributed through holes 20 are provided at the top of the external thread rings 21. The bottom ends of the through holes 20 communicate with the inside of the standby filter element 19. That is, the engine oil flowing downward along the through holes 20 is filtered in multiple stages from top to bottom along the inside of the standby filter element 19, and then flows vertically downward along the inside of the main filter channel 18; a set of internal thread holes 22 are provided on the inner wall of the standby filter channel 17 corresponding to the external thread rings 21. The external thread rings 21 are threadedly connected to the internal thread holes 22 to control the detachable connection between the standby filter element 19 and the standby filter channel 17. That is, the inside of the housing 10 is opened through the end cover 26, and then the main rotary filter element 11 is replaced, and the external thread rings 21 are rotated to replace and repair the standby filter element 19 and other operations.

[0027] The working principle of the present utility model is as follows: At the idle part of the present device, all the above-mentioned driving parts, which refer to power elements, electrical parts and the adapted power supply, are connected by wires. The electrical connection is completed for the sequential working order among the electrical parts. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and will not explain the electrical control. When in use, through pipe connection, the engine oil inlet 12 and the discharge hole 25 are connected to the engine oil chassis and the engine. Then, under the action of the oil pump, the engine oil is controlled to fall along the engine oil inlet 12. The engine oil transferred to the conical feeding port 13 enters the main rotary filter element 11 through the mesh holes 14 for multi-stage filtration. Then the filtered engine oil is transferred into the mesh holes 14 and then transmitted backward through the discharge hole 25. When the main rotary filter element 11 is blocked inside, the bypass valve 15 is opened under the pressure at the top. Then the engine oil passes through the bypass valve 15 and enters the upper side of the standby filter element 19, passes through the standby filter element 19 for multi-stage filtration, and then is directly transferred into the conical transmission port 24 under the action of gravity.

[0028] The above has made a detailed description of the preferred embodiment of this patent, but this patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of this patent.
