Description

Technical Field

[0001] This invention belongs to the field of diesel engine technology, specifically relating to a lubricating oil system for diesel engines and its usage method. Background Technology

[0002] The lubrication system is of great significance for the safe and reliable operation of diesel engines. Specifically, lubricating oil plays the following important roles in diesel engines: 1. Reducing the coefficient of friction of moving parts, slowing down wear of moving parts, and improving service life; 2. Reducing friction loss and improving effective power; 3. Cleaning and cooling moving parts; 4. Sealing and isolating.

[0003] However, in winter, especially in frigid regions like the Northwest, the internal lubricating oil is prone to freezing, making it difficult to start the diesel engine. Furthermore, most existing diesel engines lack proper preheating measures before starting, or they heat the lubricating oil through heat transfer during preheating, resulting in a slow oil temperature rise and consequently affecting the engine's starting speed. Summary of the Invention

[0004] In view of the above-mentioned defects or improvement needs of the prior art, the present invention provides a lubricating oil system and method for use in diesel engines. Its purpose is to not only quickly preheat the lubricating oil and the interior of the diesel engine before starting the diesel engine, thereby improving the starting efficiency of the diesel engine, but also to achieve reliable circulation of the lubricating oil during the operation of the diesel engine, ensuring the working performance of the diesel engine.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a lubricating oil system for a diesel engine, the lubricating oil system comprising a lubricating oil tank, a preheating assembly, a cooling assembly, and a pressurizing assembly; The lubricating oil tank is filled with lubricating oil; The preheating assembly includes a heating module and a circulating pump. The fixed end of the heating module is located on the housing of the lubricating oil tank, and the heating end of the heating module is located at the bottom of the lubricating oil tank to heat the lubricating oil. The outlet of the lubricating oil tank is connected to the inlet of the circulating pump, and the outlet of the circulating pump is used to introduce the lubricating oil into the diesel engine. The cooling assembly includes an oil pump and a cooler. The inlet of the oil pump is connected to the outlet of the diesel engine oil pan. The outlet of the oil pump, the cooler, and the inlet of the lubricating oil tank are connected in sequence. The booster assembly includes a booster pump, the outlet of the lubricating oil tank is connected to the inlet of the booster pump, and the outlet of the booster pump is used to introduce lubricating oil into the diesel engine.

[0006] Optionally, the lubricating oil system further includes a control component, which includes a sensor module, an AC power supply, and a data processing controller. The sensor module is used to measure the performance parameters of the lubricating oil in the lubricating oil tank in real time. The AC power supply is electrically connected to the heating end of the heating module. The data processing controller is electrically connected to both the sensor module and the AC power supply to control the performance parameters of the lubricating oil within a set range by adjusting the current of the AC power supply.

[0007] Optionally, the performance parameters are one or both of temperature and pressure, with the temperature set within a range of 25-35℃ and the pressure set within a range of 2-3kg.

[0008] Optionally, the heating module includes a metal block and a plurality of heating rods, the metal block being inserted into the housing of the lubricating oil tank, and the plurality of heating rods being inserted into the metal block at intervals.

[0009] Optionally, the heating module further includes an insulating base, which is fixedly connected to the metal block. The insulating base is attached to the outer wall of the lubricating oil tank and is fixedly connected to the outer wall of the lubricating oil tank.

[0010] Optionally, the cooling assembly further includes a bypass valve, the inlet of which is connected to the outlet of the plurality of oil pumps, and the outlet of which is connected to the inlet of the plurality of coolers.

[0011] Optionally, the booster assembly further includes two first filters, with the outlet of each lubricating oil tank connected to the inlet of each first filter, and the outlet of the first filter connected to the inlet of the booster pump.

[0012] Optionally, the lubricating oil system includes a safety interlock valve, which is equipped with multiple sensors. The multiple sensors are used to detect the performance parameters of the lubricating oil, and the safety interlock valve is configured to control the diesel engine to stop when the multiple sensors detect an abnormality in the lubricating oil.

[0013] Optionally, the lubrication system also includes a tap for mounting on the diesel engine housing to sample the lubrication oil.

[0014] In a second aspect, the present invention provides a method of using a lubricating oil system for a diesel engine, the method being based on the lubricating oil system for a diesel engine described in the first aspect, the method comprising: Before starting the diesel engine, the heating module heats the lubricating oil, and the circulation pump is started so that the heated lubricating oil is pumped into the diesel engine. When the diesel engine starts, the heating module and the circulation pump stop, while the oil pump, the cooler, and the booster pump start. The oil pump pumps the lubricating oil discharged from the diesel engine oil pan outlet into the cooler for cooling and then returns it to the lubricating oil tank. The booster pump pressurizes the lubricating oil in the lubricating oil tank and then introduces it into the diesel engine.

[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: In the lubrication system for a diesel engine provided in this embodiment of the invention, before starting the diesel engine in extremely cold regions, the lubricating oil is first heated by a heating module. The heating module is reliably fixed to the lubricating oil tank via a fixed end, and its heating end extends into the tank to directly heat the lubricating oil. This high heating efficiency allows the lubricating oil to quickly heat up and lubricate the diesel engine, improving its starting efficiency. Next, the circulation pump is started, pumping the heated lubricating oil into the diesel engine. The heated lubricating oil flows rapidly within the engine, providing lubrication and simultaneously heating internal components to prevent cold starts, further improving starting efficiency.

[0017] When the diesel engine starts, the heating module and circulation pump stop, completing the preheating of the lubricating oil and the engine's internal components. Correspondingly, the oil extraction pump, cooler, and booster pump start. On one hand, the oil extraction pump pumps the lubricating oil discharged from the diesel engine oil pan into the cooler for cooling and then returns it to the lubricating oil tank. During startup, the operation of internal engine components causes the lubricating oil to heat up rapidly. By recovering the lubricating oil from the oil pan and sending it to the cooler for cooling before finally returning it to the lubricating oil tank, reliable circulation of the lubricating oil is achieved, preventing overheating and coking. On the other hand, the booster pump pressurizes the lubricating oil in the lubricating oil tank and introduces it into the diesel engine. The pressurized lubricating oil has better flow properties, achieving rapid circulation for lubrication. During this rapid flow, it also carries away some of the heat from inside the diesel engine, ensuring its operating performance. Furthermore, the pressurized lubricating oil can quickly accumulate and be recovered in the diesel engine oil pan for simultaneous and rapid cooling.

[0018] In other words, the lubricating oil system for diesel engines provided in this embodiment of the invention can not only quickly preheat the lubricating oil and the interior of the diesel engine before starting the diesel engine, thereby improving the starting efficiency of the diesel engine, but also achieve reliable circulation of the lubricating oil during the operation of the diesel engine, ensuring the working performance of the diesel engine.

[0026] Example: Figure 1 This is a schematic diagram of a lubricating oil system for a diesel engine provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the lubricating oil system includes a lubricating oil tank 1, a preheating component, a cooling component, and a pressurizing component.

[0027] The lubricating oil tank 1 is filled with lubricating oil.

[0028] The preheating assembly includes a heating module 21 and a circulating pump 22. The fixed end of the heating module 21 is located on the housing of the lubricating oil tank 1, and the heating end of the heating module 21 is located at the bottom of the lubricating oil tank 1 to heat the lubricating oil. The outlet of the lubricating oil tank 1 is connected to the inlet of the circulating pump 22, and the outlet of the circulating pump 22 is used to introduce the lubricating oil into the diesel engine 100.

[0029] The cooling assembly includes an oil pump 31 and a cooler 32. The inlet of the oil pump 31 is connected to the outlet of the oil sump of the diesel engine 100. The outlet of the oil pump 31, the cooler 32 and the inlet of the lubricating oil tank 1 are connected in sequence.

[0030] The booster assembly includes a booster pump 41, with the outlet of the lubricating oil tank 1 and the inlet of the booster pump 41 connected. The outlet of the booster pump 41 is used to introduce lubricating oil into the diesel engine 100.

[0031] In the lubrication system for a diesel engine provided in this embodiment of the invention, before starting the diesel engine 100 in extremely cold regions, the lubricating oil is first heated by the heating module 21. The heating module 21 is reliably fixed to the lubricating oil tank 1 via a fixed end, and its heating end extends into the tank 1 to directly heat the lubricating oil. This high heating efficiency allows the lubricating oil to quickly heat up and lubricate the diesel engine 100, improving the starting efficiency. Next, the circulation pump 22 is started, pumping the heated lubricating oil into the diesel engine 100. The heated lubricating oil flows rapidly within the engine, providing lubrication and simultaneously heating the internal components, preventing cold starts and further improving starting efficiency.

[0032] When the diesel engine 100 starts, the heating module 21 and the circulation pump 22 stop, completing the preheating of the lubricating oil and the interior of the diesel engine 100. Correspondingly, the oil pump 31, cooler 32, and booster pump 41 start. On one hand, the oil pump 31 pumps the lubricating oil discharged from the oil pan of the diesel engine 100 into the cooler 32 for cooling, and then recovers it to the lubricating oil tank 1. During startup, the operation of the internal components of the diesel engine 100 causes the lubricating oil to heat up rapidly. By recovering the lubricating oil from the oil pan and sending it to the cooler 32 for cooling before finally recovering it to the lubricating oil tank 1, reliable circulation of the lubricating oil can be achieved, preventing the lubricating oil from overheating and coking. On the other hand, the booster pump 41 pressurizes the lubricating oil in the lubricating oil tank 1 and introduces it into the diesel engine 100. After pressurization, the lubricating oil has better flow properties, achieving rapid circulation for lubrication. Furthermore, during this rapid flow, some of the heat inside the diesel engine 100 can be carried away, ensuring the working performance of the diesel engine 100. Furthermore, the pressurized lubricating oil can quickly collect and be recovered in the oil pan of the diesel engine, facilitating simultaneous and rapid cooling.

[0033] In other words, the lubricating oil system for a diesel engine provided in this embodiment of the invention can not only quickly preheat the lubricating oil and the interior of the diesel engine 100 before starting the diesel engine 100, thereby improving the starting efficiency of the diesel engine 100, but also achieve reliable circulation of the lubricating oil during the operation of the diesel engine 100, ensuring the working performance of the diesel engine 100.

[0034] For example, the lubricating oil tank 1 has a square structure and is disposed inside the diesel engine 100, located between the diesel engine 100 housing and the crankcase.

[0035] Figure 2 This is a schematic diagram of the arrangement of the control components provided in an embodiment of the present invention, as shown below. Figure 2As shown, the lubricating oil system also includes a control component, which includes a sensor module 51, an AC power supply 52, and a data processing controller 53. The sensor module 51 is used to measure the performance parameters of the lubricating oil in the lubricating oil tank 1 in real time. The AC power supply 52 is electrically connected to the heating end of the heating module 21. The data processing controller 53 is electrically connected to both the sensor module 51 and the AC power supply 52 to control the performance parameters of the lubricating oil within a set range by adjusting the current of the AC power supply 52.

[0036] In the above embodiment, the sensor module 51 can measure the performance parameters of the lubricating oil in the lubricating oil tank 1 in real time, while the data processing controller 53 processes and analyzes the data collected by the sensor module 51 and regulates the current of the AC power supply 52, thereby ensuring that the performance parameters of the lubricating oil are within the normal range, and thus realizing the automated and intelligent control of the lubricating oil preheating.

[0037] Specifically, the performance parameters are one or both of temperature and pressure, with the temperature setting range being 25-35℃ and the pressure setting range being 2-3kg.

[0038] For example, the sensor module 51 can be one or both of a temperature sensor and a pressure sensor, ensuring that the temperature and pressure of the lubricating oil are within a suitable range during the preheating process. Specifically, regarding temperature, when the temperature sensor detects the lubricating oil temperature and transmits it to the data processing controller 53, the data processing controller 53 processes and analyzes the data. If the lubricating oil temperature is higher than the set range, the data processing controller 53 controls the AC power supply 52 to reduce the output current or stop supplying power until the temperature detected by the sensor module 51 reaches the set range. Similarly, when the temperature sensor detects the lubricating oil temperature and transmits it to the data processing controller 53, if the data processing controller 53 processes the data and analyzes the data, if the lubricating oil temperature is lower than the set range, the data processing controller 53 controls the AC power supply 52 to increase the output current until the temperature detected by the sensor module 51 reaches the set range. Furthermore, during diesel engine operation, the sensor module 51 can also perform real-time measurement of the lubricating oil.

[0039] It should be noted that the performance parameters of the lubricating oil are set manually. Correspondingly, the lubricating oil temperature during the preheating stage is set to 25-35℃, meaning that preheating can be completed quickly within this range. During the diesel engine's 100°C operating stage, the lubricating oil temperature needs to be controlled between 70-105℃. Additionally, performance parameters can also include flow rate, etc., and this invention does not limit this.

[0040] For example, the sensor module 51 is fixed to the housing of the lubricating oil tank 1.

[0041] For example, the control component also includes a warning device that is electrically connected to the data processing controller 53. When the data processing controller 53 processes and analyzes the data and determines that the lubricating oil temperature is not within the set range, the data processing controller 53 controls the warning device to issue a warning signal.

[0042] See also Figure 2 The heating module 21 includes a metal block 211 and multiple heating rods 212. The metal block 211 is inserted into the housing of the lubricating oil tank 1, and the multiple heating rods 212 are inserted into the metal block 211 at intervals.

[0043] In the above embodiment, multiple heating rods 212 can simultaneously heat the metal block 211, resulting in high heating efficiency. Furthermore, the metal block 211 increases the contact area with the lubricating oil, enhancing heating uniformity and further improving the heating efficiency of the lubricating oil, thereby increasing the starting efficiency of the diesel engine 100.

[0044] For example, the metal block 211 can be an aluminum block.

[0045] Furthermore, there can be three or four heating rods 212, etc., and the present invention does not limit this. The heating rods 212 can have a U-shaped structure, thereby increasing the heat transfer area and ensuring uniformity during the heating process.

[0046] Furthermore, the heating module 21 also includes an insulating base 213, which is fixedly connected to the metal block 211. The insulating base 213 is attached to and fixedly connected to the outer wall of the lubricating oil tank 1. The insulating base 213 not only supports the metal block 211 but also secures the entire heating module 21 to the lubricating oil tank 1 and provides insulation.

[0047] For example, the heat insulation base 213 can be a nanoporous plate or a vacuum heat insulation plate.

[0048] See you again Figure 1 The cooling assembly also includes a bypass valve 33, the inlet of which is connected to the outlet of a plurality of oil pumps 31, and the outlet of which is connected to the inlet of a plurality of coolers 32.

[0049] In the above embodiment, the bypass valve 33 can adjust the proportion of lubricating oil pumped out by the oil pump 31 that enters the cooler 32.

[0050] For example, when the temperature of the lubricating oil pumped out by the oil pump 31 is high, the bypass valve 33 is opened slightly or completely closed, and most or all of the lubricating oil flows directly into the cooler 32, improving cooling efficiency. When the temperature of the lubricating oil pumped out by the oil pump 31 is low, the bypass valve 33 is opened slightly or completely open, and a small portion of the lubricating oil flows into the cooler 32.

[0051] In addition, the booster assembly also includes two first filters 42. The outlet of the lubricating oil tank 1 is connected to the inlet of each first filter 42, and the outlet of each first filter 42 is connected to the inlet of the booster pump 41. The first filters 42 can filter the circulating lubricating oil, removing impurities in the lubricating oil in a timely manner to prevent wear on the pump body, valves, and internal parts of the diesel engine 100. Furthermore, the two first filters 42 can serve as backups for each other, ensuring that if one filter fails, the other filter can still operate, and the damaged filter can be replaced promptly.

[0052] For example, a first check valve 8 is provided between the outlet of the first filter 42 and the inlet of the booster pump 41 to prevent lubricating oil backflow. A second check valve 9 is provided between the outlet of the first check valve 8 and the inlet of the lubricating oil tank 1, which can directly return part of the filtered lubricating oil to the lubricating oil tank 1, that is, to achieve separate filtration and recovery.

[0053] Similarly, the cooling assembly also includes multiple second filters 34, the outlet of the oil pump 31 is connected to the inlet of each second filter 34, and the outlet of each second filter 34 is connected to the inlet of the cooler 32.

[0054] For example, there are four second filters 34, of which two second filters 34 form a group.

[0055] In this embodiment, the lubricating oil system includes a safety interlock valve 6, which is equipped with multiple sensors. These sensors are used to detect the performance parameters of the lubricating oil. The safety interlock valve 6 is configured such that when the multiple sensors detect an abnormality in the lubricating oil, the safety interlock valve 6 controls the diesel engine 100 to stop (or reduce its power).

[0056] In other words, the safety interlock valve 6 can control the diesel engine 100 in a timely manner by collecting sensor data, thereby preventing accidents from occurring.

[0057] For example, the lubricating oil system also includes a tap 7, which is installed on the housing of the diesel engine 100 to sample the lubricating oil. The tap 7 can sample the lubricating oil as needed without disassembling the entire diesel engine 100, thereby enabling rapid analysis and diagnosis of the lubricating oil.

[0058] Figure 3 This is a flowchart illustrating a method of using a lubricating oil system for a diesel engine, as provided in an embodiment of the present invention. Figure 3 As shown, this method of use is based on the aforementioned lubricating oil system for diesel engines, and the method of use includes: S1. Before starting the diesel engine 100, the lubricating oil is heated by the heating module 21, and the circulation pump 22 is started so that the heated lubricating oil is pumped into the diesel engine 100.

[0059] S2. When the diesel engine 100 starts, the heating module 21 and the circulation pump 22 stop, while the oil pump 31, the cooler 32 and the booster pump 41 start. The oil pump 31 pumps the lubricating oil discharged from the oil pan of the diesel engine 100 into the cooler 32 for cooling and then returns it to the lubricating oil tank 1. The booster pump 41 pressurizes the lubricating oil in the lubricating oil tank 1 and then introduces it into the diesel engine 100.

[0060] The present invention provides a method for using a lubricating oil system for a diesel engine, which can not only quickly preheat the lubricating oil and the interior of the diesel engine 100 before starting the diesel engine 100, thereby improving the starting efficiency of the diesel engine 100, but also achieve reliable circulation of the lubricating oil during the operation of the diesel engine 100, ensuring the working performance of the diesel engine 100.

[0061] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
