[0002] Marine diesel engines are the main power sources of ships, and the stability and reliability of their operation are directly related to the safe navigation of ships. As an auxiliary system of diesel engines, the servo lubricating oil system can effectively reduce diesel engine wear and reduce failure rates, thereby improving the safety performance of ships. During the operation of marine diesel engines, they require the assistance of a lubrication system to reduce friction and wear.

[0021] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the illustrations, rather than being drawn according to the number, shape, and size of the components in actual implementation. In actual implementation, the types, quantities, and proportions of the components may be arbitrarily changed, and the component layout type may also be more complex.

[0022] As Figure 1 shown, this embodiment provides a servo oil lubricating oil system independent of the main lubricating oil system of a diesel engine. The system includes a lubricating oil circulation tank 1, an oil pump 2, a heat exchanger 3, a filtering assembly, a lubricating oil separating unit 4, and a lubricating oil cleaning unit 5.

[0023] The lubricating oil circulation tank 1 and the oil pump 2 are connected through an oil pipe. The lubricating oil circulation tank 1 and the oil pump 2 form a fuel supply assembly. The oil pump 2 can draw lubricating oil from the lubricating oil circulation tank 1 to supply to the diesel engine. The number of the oil pumps 2 in this embodiment is two, and the two oil pumps 2 are arranged in parallel. The two oil pumps 2 are one main and one standby. When one of the oil pumps 2 has a problem, the other oil pump 2 can be started in time for lubricating oil supply. In this embodiment, the oil pump 2 is a variable pump and can adjust the flow rate, thereby controlling the flow rate of the lubricating oil.

[0024] The heat exchanger 3 is used to cool the lubricating oil. A cooling water inlet pipe 31 and a cooling water outlet pipe 32 are connected to the heat exchanger 3. The cooling water inlet pipe 31 supplies cooling water to the heat exchanger 3, and the cooling water outlet pipe 32 discharges the cooling water that has passed through the heat exchanger 3. The heat exchanger 3, the cooling water inlet pipe 31, and the cooling water outlet pipe 32 form a cooling assembly.

[0025] The filtration assembly includes a manual filter 6 and an automatic backwashing filter 7. The manual filter 6 and the automatic backwashing filter 7 are arranged in parallel. Both the manual filter 6 and the automatic backwashing filter 7 are used to filter impurities in the lubricating oil to keep the lubricating oil clean. The automatic backwashing filter 7 is equipped with a differential pressure sensor. The automatic backwashing filter 7 can detect the differential pressure before and after itself. When the differential pressure is too large, it indicates that the automatic backwashing filter 7 is blocked. At this time, the automatic backwashing filter 7 will switch the valve to make the lubricating oil flow reversely to wash away the impurities. At the same time, the drain port of the automatic backwashing filter 7 is opened, and the washed-down impurities are discharged from the drain port. When the automatic backwashing filter 7 fails or is under maintenance, the manual filter 6 can be used to filter the lubricating oil to ensure that the particle size of the lubricating oil entering the diesel engine meets the requirements. When the manual filter 6 is blocked, the filter residue can be manually cleaned.

[0026] The lubricating oil separation unit 4 is a device for purifying lubricating oil to ensure the stability and reliability of the system operation. The lubricating oil cleaning unit 5 is a system for lubricating oil purification and maintenance in a ship. Its main function is to remove impurities, moisture, and pollutants in the lubricating oil to ensure the cleanliness and performance of the lubricating oil. Both the lubricating oil separation unit 4 and the lubricating oil cleaning unit 5 use the centrifugal separation method to separate the lubricating oil, impurities, and water. The separated clean oil can be reused.

[0027] In this embodiment, the oil supply assembly, the cooling assembly, the filtration assembly, the diesel engine, the lubricating oil separation unit 4, and the lubricating oil cleaning unit 5 form a circulation loop. Specifically, the outlet ports of the two oil pumps 2 in the oil supply assembly are connected in parallel to the inlet port of the heat exchanger 3. When the lubricating oil enters the heat exchanger 3, the heat exchanger 3 cools the lubricating oil. The inlet ports of the manual filter 6 and the automatic backwashing filter 7 are connected in parallel to the outlet port of the heat exchanger 3. The outlet ports of the manual filter 6 and the automatic backwashing filter 7 are connected in parallel to the inlet port of the diesel engine. The outlet port of the diesel engine is connected in series with the inlet port of the lubricating oil separation unit 4. The outlet port of the lubricating oil separation unit 4 is connected to the lubricating oil circulation tank 1 to make the lubricating oil return to the lubricating oil circulation tank 1 again. The inlet port of the lubricating oil cleaning unit 5 is connected in series with the drain port of the automatic backwashing filter 7. The outlet port of the lubricating oil cleaning unit 5 is connected to the lubricating oil circulation tank 1.

[0028] In this embodiment, a flow meter 8 is connected in series at the oil inlet of the heat exchanger 3. Since the oil pump 2 can adjust the flow rate of the lubricating oil in the entire oil circuit, according to different types of diesel engines, the oil pump 2 can adjust the flow rate to meet the usage requirements of different types of diesel engines. During this process, the flow meter 8 is used to monitor whether the flow rate of the lubricating oil is adjusted properly.

[0029] In summary, the implementation process of the servo oil lubricating oil system in this embodiment is as follows: Start one of the oil pumps 2, and the oil pump 2 sends the lubricating oil to the heat exchanger 3. At this time, the cooling water and the lubricating oil in the heat exchanger 3 exchange heat, thereby cooling the lubricating oil. The cooled lubricating oil will flow to the automatic backwashing filter 7 for filtration, so that the clean lubricating oil can flow into the diesel engine for use. When the used lubricating oil flows out of the diesel engine, it will first enter the lubricating oil separation unit 4, and the lubricating oil separation unit 4 filters the lubricating oil, so that the purified oil flows back to the lubricating oil circulation tank 1. Among them, when the backwashing filter detects that the pressure difference is too large, the backwashing filter performs backwashing. The lubricating oil after backwashing first enters the lubricating oil cleaning unit 5 for separation, where the impurities are discharged and the purified oil flows back into the lubricating oil circulation tank 1 again.

[0030] In this embodiment, the diesel engine is supplied with oil by adopting an independent servo oil lubricating oil system. Compared with the traditional oil supply method, the system in this embodiment can accurately control the oil supply volume, ensure that each component of the diesel engine is properly lubricated, thereby improving the efficiency and service life of the diesel engine; the servo oil lubricating oil system can filter and purify the used lubricating oil, improve the lubricating oil quality, and thus help to improve the stability and reliability of the servo oil lubricating oil system.

[0031] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
