Description

Technical Field

[0001] This invention relates to the field of engine technology equipment, and more specifically to an intelligent oil reservoir with an integrated oil-gas separator. Background Technology

[0002] Engine oil, as the "blood" of the engine, directly determines the engine's operational stability, lubrication effect, and service life. During engine operation, an oil-gas mixture containing oil vapor is generated in the crankcase. Direct discharge of this mixture would waste oil and pollute the environment. Furthermore, oil vapor entering the intake system would affect engine combustion efficiency. Therefore, an oil-gas separator is needed to separate the oil from the gas, recover the oil, and purify the gas.

[0003] Meanwhile, the pressure stability of the engine oil system is crucial. Excessive pressure can lead to oil leaks and pipe damage, while insufficient pressure can prevent oil supply to all lubrication points, exacerbating component wear. Furthermore, the operating temperature and water content of the oil significantly affect its lubrication performance. When the oil temperature is too low, its viscosity increases, its fluidity decreases, and it becomes difficult to quickly form a stable oil film, easily leading to dry friction wear of components. When the oil temperature is too high, its viscosity decreases, the oil film's load-bearing capacity declines, easily causing wear, overheating, and even bearing burnout. Water mixed in the oil will damage its lubrication performance, causing emulsification and deterioration, corroding internal engine metal parts, and shortening the service life of both the oil and the engine.

[0004] Currently, Chinese patent publication number CN223089380U discloses a separation component, an oil reservoir, and an engine, including a centrifugal channel and a separator. The inlet of the centrifugal channel is adapted to allow an oil-gas mixture to pass through. The separator has a centrifugal separation chamber, the inlet of which is connected to the outlet of the centrifugal channel. At least part of the centrifugal channel is arc-shaped.

[0005] While this separation component, oil reservoir, and engine improve the oil-gas separation effect, current engine oil treatment systems mostly use independent modules for oil-gas separation, pressure regulation, and oil temperature control. Furthermore, they lack sufficient control and monitoring capabilities for the oil. Therefore, there is an urgent need for a highly integrated, collaborative, and intelligently controllable oil treatment device to address the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent oil reservoir with an integrated oil-gas separator, which solves the problems of low integration, complex piping, and large space occupation of the oil-gas separator and oil reservoir in the prior art; at the same time, it solves the problems of low separation efficiency and insufficient ultrafine oil droplet capture capacity of the traditional oil-gas separator structure.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: An intelligent oil reservoir with an integrated oil-gas separator includes a housing. The housing comprises an upper oil reservoir shell and a lower oil reservoir shell that matches the upper oil reservoir shell. The upper and lower oil reservoir shells form an oil storage chamber. An oil suction port is provided on one side of the lower oil reservoir shell. An electronic oil pump is provided on one side of the housing and is connected to the oil suction port. An air inlet is also provided on one side of the oil suction port. An oil-gas separation device is also provided on the upper oil reservoir shell located on the side of the electronic oil pump. An oil outlet is also provided on one side of the lower oil reservoir shell. The oil-gas separation device includes a protrusion located on one side of the upper housing of the oil reservoir. A support plate fixedly connected to the inner wall of the upper housing of the oil reservoir is provided inside the protrusion. An air port is provided on one side of the support plate. A baffle plate is also provided on the support plate, which is perpendicular to the support plate and symmetrically arranged to supply airflow through in an S-shape. A perforated plate is also provided on one side of the baffle plate. An impact plate is also provided behind the perforated plate. An oil outlet is also provided below the perforated plate and the impact plate. A connecting device communicating with the oil storage chamber is also provided on the side of the support plate away from the air port. An air outlet for connecting to the engine manifold is also provided on one side of the protrusion. A first oil-resistant polyurethane sponge block is also provided on the inner walls on both sides between the impact plate and the perforated plate.

[0008] Through the above technical solution, the integrated design of the oil reservoir body and the oil-gas separator, with the upper shell of the oil reservoir and the protrusions of the oil-gas separator integrally formed, replaces the traditional separate layout of the oil-gas separator and oil reservoir, and the external pipeline connection. This significantly reduces the installation space occupied in the engine compartment, reduces a large number of external pipeline joints, and fundamentally reduces the risk of pipeline leakage, loose joints, and pipeline blockage, significantly improving the integration and operational reliability of the oil system. A four-stage composite oil-gas separation structure is designed, consisting of S-shaped inertial deflection, perforated rectification, impact separation, and microporous adsorption. A continuous S-shaped deflection is formed by symmetrically arranged upper and lower baffles. The system utilizes a shaped airflow channel and the inertial centrifugal force generated by the airflow deflection to achieve primary coarse separation of large-diameter oil droplets. Subsequently, a perforated plate throttles and rectifyes the airflow, reducing turbulence, while a frontal impact plate facilitates secondary separation of medium-diameter oil droplets. The three-dimensional microporous structure of the first oil-resistant polyurethane sponge block adsorbs and captures fine oil droplets in the airflow, achieving tertiary fine separation. Finally, the separated oil flows directly back to the oil storage chamber through the oil outlet and connecting device, eliminating the need for an additional return oil pipeline. This shortens the return path and avoids problems such as freezing and blockage of the return oil pipeline, significantly reducing oil loss and hydrocarbon pollutant emissions from the exhaust. Simultaneously, after the first oil-resistant polyurethane sponge block is saturated with oil, excess oil naturally drips off due to gravity, and it can effectively adsorb impurities in the gas, increasing the oil's lifespan.

[0009] Further features: An air inlet is provided on one side of the upper housing of the oil reservoir, and a parallel bidirectional pressure valve assembly is provided on the air inlet.

[0010] Through the above technical solution, by integrating a parallel bidirectional pressure valve assembly into the air inlet, dual functions of positive negative pressure air inlet and reverse positive pressure relief are achieved on the same installation interface. This replaces the traditional single-way air inlet valve, which can only achieve single negative pressure balance. It eliminates the need for additional pressure relief pipelines, valve bodies, and installation points. Without altering the oil reservoir structure or increasing engine compartment installation space, it expands the compliant air filter-side closed-loop air outlet pressure relief capability, enabling a single interface to handle both air inlet and pressure relief conditions. This significantly simplifies the crankcase ventilation system structure and further enhances the integration and modularity of the oil reservoir. Simultaneously, it forms a dual-loop collaborative closed-loop control with the pressure adaptive PCV valve at the air outlet, solving the problem that the traditional single PCV valve solution cannot simultaneously manage engine pressure under all operating conditions: the main loop (PCV valve + intake manifold) is responsible for precise micro-negative pressure adjustment under engine idling and low-load conditions, while the auxiliary loop (bidirectional valve assembly reverse pressure relief unit + ...) The air filter clean side is responsible for positive pressure relief under engine high load, high speed and turbocharger pressure conditions, while the positive air injection unit is responsible for negative pressure over-limit protection under engine rapid deceleration and idling coasting conditions, so that the system pressure is always stable within the safe range throughout the entire operating range of the engine from cold start, idling to full load.

[0011] Further features: The impact plate is provided with several blocking protrusions, and ventilation holes are also provided around the impact plate.

[0012] By using the above technical solution, several blocking protrusions are arrayed on the surface of the impact plate, which greatly increases the contact area and collision probability between the oil and gas flow and the impact surface, thereby improving the collision separation efficiency of medium-sized oil droplets. At the same time, the uniformly distributed ventilation holes around the impact plate can uniformly distribute the airflow after the impact, avoiding the problem of excessively high local flow velocity and secondary entrainment of separated oil droplets caused by concentrated airflow impact. This ensures that the airflow passes through the subsequent sponge adsorption unit uniformly and at low speed, further enhancing the adsorption and capture effect of fine oil droplets and improving the stability and consistency of oil-gas separation.

[0013] Further configuration: The device housing on one side of the electronic oil pump is also provided with a filler port, the filler port is provided with an oil filler cap that is threadedly connected to the filler port, and the oil filler cap is also provided with a rotating handle.

[0014] By integrating the oil filler cap onto the same side of the electronic oil pump housing, the overall structure of the oil reservoir is optimized, adapting to the operating space in the engine compartment and significantly improving the convenience of oil filling. Simultaneously, the threaded oil filler cap, combined with a rotating handle, allows for quick opening and closing and reliable sealing of the filler cap, effectively preventing oil splashing and leakage during vehicle operation. It also isolates external dust, impurities, and moisture from entering the oil reservoir and contaminating the oil, improving oil cleanliness and extending oil lifespan.

[0015] Further configuration: The inner wall of the protrusion is also provided with an auxiliary separation device, which includes a blocking block located around the baffle plate, a wire mesh bag located on the side of the blocking block away from the air port, and a second oil-resistant polyurethane sponge block inside the wire mesh bag.

[0016] By adding an auxiliary separation device to the inner wall of the protrusion through the above technical solution, a fine oil droplet deep separation unit is constructed. The airflow is deflected and redirected again by the blocking block, which prolongs the residence time of oil and gas in the separation chamber. In conjunction with the second oil-resistant polyurethane sponge block in the wire mesh bag, deep adsorption and capture are performed. At the same time, the wire mesh bag can fully wrap and fix the sponge block, avoiding sponge displacement, deformation and damage caused by long-term high-speed airflow impact, thus ensuring the stability of the separation effect.

[0017] Further configuration: A baffle plate is provided in the oil storage cavity between the upper shell and the lower shell of the oil can, and the baffle plate is provided with several baffle holes.

[0018] By using the above technical solution, a baffle plate with arrayed anti-surge holes is installed inside the oil reservoir. This effectively suppresses the sloshing and splashing of engine oil in the reservoir under extreme conditions such as bumpy roads, acceleration and deceleration, and sharp turns. It significantly reduces the fluctuation range of the engine oil level, reduces the amount of oil vapor evaporation from the source, and reduces the amount of oil-gas mixture generated in the reservoir. At the same time, the anti-surge holes on the baffle plate ensure the free flow of engine oil in the reservoir, ensuring that the oil pump suction port is always submerged below the engine oil level. This completely avoids lubrication interruption and engine dry friction damage caused by the suction port being sucked into the oil, and significantly improves the lubrication reliability of the engine under extreme conditions.

[0019] Further feature: The lower housing of the oil container is also provided with an oil drain hole, and the oil drain hole is provided with an oil drain plug.

[0020] By using the above technical solution, an oil drain hole and matching drain plug are installed at the lowest position of the lower housing of the oil reservoir, which enables quick and thorough draining of oil during oil changes without disassembling the oil reservoir itself. This shortens the oil change time and significantly reduces maintenance difficulty and costs. At the same time, the oil drain hole, located at the lowest point of the housing, can completely drain sludge, metal shavings, impurities, and other debris that have accumulated in the oil reservoir over time along with the waste oil. This prevents impurities from entering the engine lubrication system and causing abnormal wear of components, thus improving the cleanliness of the oil change and extending the engine's service life.

[0021] Further configuration: The air outlet is also equipped with a pressure adaptive PCV valve.

[0022] Through the above technical solution, a pressure adaptive PCV valve is integrated into the exhaust port. This valve can collect real-time signals of the engine manifold vacuum and crankcase pressure, and automatically adjust the valve opening according to different engine operating conditions. This precisely controls the stability of the crankcase pressure, replacing the passive adjustment method of the traditional fixed PCV valve. It solves the problems of excessively low pressure at idle and excessively high pressure under high load conditions, effectively preventing malfunctions such as oil leakage, oil-gas combustion, and oil dilution. At the same time, it works in conjunction with the pre-mounted integrated oil-gas separator to ensure that the purified gas is stably delivered to the intake manifold, realizing pressure adaptive adjustment under all engine operating conditions and significantly improving the adaptability and operational reliability of the oil system.

[0023] Further features include: an electronic liquid level sensor extending into the device housing on one side of the oil filler cap; a controller on the device housing; and a temperature sensor and a water content sensor connected to the controller in the oil storage chamber.

[0024] Through the above technical solution, an intelligent monitoring and early warning system for engine oil status is constructed using electronic level sensors, temperature sensors, water content sensors, and a vehicle-level controller. This system can collect key parameters such as engine oil level, operating temperature, and water content in real time with high precision. The controller can analyze the collected data in real time. When abnormal conditions occur, such as excessively low or high engine oil level, temperature exceeding threshold, or excessive water content leading to oil emulsification, it can immediately send graded early warning signals to the vehicle ECU and instrument panel to remind the driver to perform timely inspection and maintenance. This fundamentally solves the problem of irreversible engine wear caused by the inability of traditional oil reservoirs to monitor engine oil status in real time and the failure to detect faults in a timely manner. It realizes intelligent and digital management of the engine oil system, improves the accuracy of engine lubrication system fault early warning, and significantly enhances engine operating safety and service life.

[0025] Further configuration: The connecting device includes a connecting channel located inside the oil storage chamber and communicating with the protrusion. The bottom of the connecting channel is provided with an oil outlet, and the oil outlet is provided with a plurality of oil holes. An anti-spray cap is also provided on the oil outlet below the oil holes.

[0026] Through the above technical solution, a dedicated oil return connection device with a blowout preventer was designed. The separated oil flows out evenly and at a low speed through the array of oil outlet holes in the connection channel and oil outlet. With the blowout preventer below the oil outlet providing buffering and blocking, the problem of oil splashing and secondary oil-gas mixing caused by the high-speed impact of the return oil on the oil surface of the oil storage chamber can be completely avoided, ensuring that the separated oil flows back smoothly to the oil storage chamber. At the same time, the blowout preventer can form a one-way blocking structure, effectively preventing the oil-gas mixture in the oil storage chamber from flowing back into the oil-gas separator, avoiding the problem of reduced separation efficiency, and further enhancing the long-term operational stability and separation effect of the oil-gas separation system.

[0027] In summary, this application has the following beneficial effects: 1. Highly integrated design breaks through the limitations of traditional separate layouts, integrating the oil reservoir, oil-gas separator, electronic oil pump, pressure regulating unit, and intelligent monitoring system into one unit. This replaces the traditional multi-module separate layout and complex pipeline connection scheme of engine oil system, significantly reducing the installation space in the engine compartment, reducing pipeline joints and leakage risks, improving system integration and significantly enhancing operational reliability.

[0028] 2. Multi-stage composite separation structure to improve oil-gas separation efficiency: The composite oil-gas separation structure design of S-shaped inertial deflection, perforated rectification, impact separation and dual-stage sponge adsorption can achieve efficient separation from large-diameter oil droplets to fine oil droplets, improve the overall oil-gas separation efficiency, significantly reduce oil consumption, and reduce engine carbon deposits and exhaust pollutant emissions.

[0029] 3. Adaptive pressure control to ensure stable system operation: The integrated adaptive pressure PCV valve and air inlet enable closed-loop precise control of crankcase pressure under all engine operating conditions, stabilizing the system pressure within the optimal range. This solves the problems of large pressure fluctuations, leakage, cavitation, and oil seal damage in traditional systems, thus improving pressure stability.

[0030] 4. Intelligent monitoring enables digital management of the engine oil system: It has built an intelligent monitoring and early warning system for engine oil status, including level, temperature, and water content. It can sense the working status of the engine oil in real time and accurately warn of faults such as oil leakage, emulsification, deterioration, and abnormal temperature. It fundamentally avoids irreversible wear of the engine caused by engine oil failure and greatly extends the service life of the engine and engine oil.

[0031] 5. Significantly improved ease of maintenance: The optimized design of the integrated filler neck and bottom drain hole greatly reduces the difficulty and time required for oil filling and changing. At the same time, the integrated structure reduces the number of vulnerable parts, extends the service life of the system, and reduces the total life cycle maintenance cost of the engine oil system.

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] The technical solution adopted in this invention is: an intelligent oil reservoir integrating an oil-gas separator, such as... Figure 1 and Figure 2 As shown, the device includes a housing 1, which is composed of an upper oil reservoir housing 101 and a lower oil reservoir housing 102. The upper oil reservoir housing 101 and the lower oil reservoir housing 102 together enclose a sealed oil storage chamber 2. An oil suction port 3 is provided on one side of the lower oil reservoir housing 102, and an oil outlet 24 is also provided on one side of the lower oil reservoir housing 102. An electronic oil pump 4 is fixedly installed on the device housing 1. The electronic oil pump 4 is sealed and connected to the oil suction port 3. An air inlet 5 is opened on the housing next to the oil suction port 3. The upper oil reservoir housing 101 extends outward from the side of the electronic oil pump 4 to form a protrusion 61. The protrusion 61 forms an independent sealed cavity, which constitutes the installation chamber of the oil-gas separation device 6.

[0036] like Figure 3 , Figure 4 and Figure 5As shown, the oil-gas separator 6 is integrated inside the protrusion 61. A support plate 62 is fixedly installed inside the cavity of the protrusion 61. The outer contour edge of the support plate 62 is fixedly connected to the inner wall of the upper shell 101 of the oil reservoir and the inner side wall of the protrusion 61. A through-type air port 63 is reserved at the lower part of the support plate 62 to realize the airflow communication between the oil storage cavity 2 and the oil-gas separator cavity. Multiple sets of baffle plates 64 are vertically fixedly installed on the surface of the support plate 62. The baffle plates 64 are arranged symmetrically and staggered, forming an S-shaped bend flow channel in the cavity after fixing, allowing the airflow to pass back and forth. A perforated plate 65 and an impact plate 66 are fixed in parallel along the airflow direction on the downstream side of the baffle plate 64. The perforated plate 65 and the impact plate 66 are vertically spaced apart. The inner walls of the perforated plate 65 and the impact plate 66 on both sides are bonded and fixed with a first oil-resistant polyurethane sponge block 610. Several blocking protrusions 9 are integrally formed on the surface of the impact plate 66, such as Figure 6 As shown, the impact plate 66 has through vent holes 10 evenly distributed around its four sides; the perforated plate 65 and the impact plate 66 have sunken oil outlets 67 uniformly distributed below them; the support plate 62 is fixedly installed with a connecting device 68 on the side away from the air outlet 63, and the upper end of the connecting device 68 is sealed and connected to the oil outlet 67; the inner wall of the protrusion 61 and located downstream of the impact plate 66 is provided with an auxiliary separation device 14, which includes a blocking block 141 fixed to the inner wall of the protrusion 61, a wire mesh bag 142 fixedly arranged on the side of the blocking block 141 away from the air outlet 63, and a second oil-resistant polyurethane sponge block 143 fixedly filled inside the wire mesh bag 142; an air outlet 69 is opened at the outer end of the protrusion 61, and a pressure adaptive PCV valve 19 is installed at the position of the air outlet 69 with an interference seal.

[0037] The upper housing 101 of the oil reservoir has a separate air inlet 7 on its side wall. The air inlet 7 is sealed and fixedly installed with a parallel two-way pressure valve PCV group 8. The parallel two-way pressure valve PCV group 8 integrates an independent and parallel arranged positive air inlet valve PCV unit and a reverse pressure relief valve PCV unit. The flow channels of the two sets of valve PCV units are isolated from each other and can be opened and closed independently. The outer interface of the valve PCV group is sealed and connected to the clean side of the vehicle air filter through a pipeline.

[0038] The connecting device 68 is fixedly arranged inside the oil storage chamber 2. The connecting device 68 has a vertically penetrating connecting channel 681. The upper end of the connecting channel 681 is connected to the oil outlet 67, and the lower end of the connecting channel 681 is formed into an oil outlet 682. Several oil outlet holes 683 are evenly opened on the end face of the oil outlet 682. The blowout preventer cap 684 is fixed below the oil outlet hole 683 by a snap-fit ​​limiter. A fixed flow guide gap is reserved between the blowout preventer cap 684 and the oil outlet 682. The baffle plate 15 is vertically fixedly installed inside the oil storage chamber 2. The upper and lower ends of the baffle plate 15 are fixedly connected to the inner top wall of the upper shell 101 of the oil pot and the inner bottom wall of the lower shell 102 of the oil pot, respectively. Several baffle holes 16 are opened in the plate array of the baffle plate 15.

[0039] like Figure 7As shown, a filler port 11 is provided on the device housing 1 above the electronic oil pump 4. The inner wall of the filler port 11 is machined with internal threads. The oil filler cap 12 is connected to the filler port 11 by external thread and screwed in to seal. The top of the oil filler cap 12 is integrally provided with a rotating handle 13. An electronic liquid level sensor 20 is vertically fixed inside the oil filler cap 12. The detection rod of the electronic liquid level sensor 20 extends vertically into the lower part of the oil storage chamber 2. A controller 21 is fixedly installed on the outer wall of the device housing 1. A temperature sensor 22 and a water content sensor 23 are respectively fixedly embedded in the inner wall of the oil storage chamber 2. The electronic liquid level sensor 20, temperature sensor 22, and water content sensor 23 are all electrically connected to the controller 21. An oil drain hole 17 is provided at the lowest position of the lower housing 102 of the oil reservoir. The inner wall of the oil drain hole 17 is provided with internal threads. An oil drain plug 18 is installed at the oil drain hole 17 by threaded sealing.

[0040] Its main working principle is as follows: During normal engine operation, the oil-gas mixture generated by the crankcase is continuously introduced into the oil reservoir 2 through the air inlet 5. The baffle 15 in the oil reservoir 2, with the help of the structure of the plate surface and the baffle hole 16, suppresses the violent shaking and splashing of the oil under the conditions of vehicle bumps, acceleration, deceleration and steering, and reduces the extra oil gas generated by secondary atomization of the oil. Under the action of the crankcase pressure difference, the oil-gas mixture smoothly enters the oil-gas separation chamber inside the protrusion 61 through the air inlet 63 at the bottom of the support plate 62.

[0041] The oil and gas flow first enters the S formed by the upper and lower staggered baffles 64 The airflow is deflected and redirected multiple times in a flow channel. Large oil droplets are impacted and condensed into liquid oil by centrifugal force, converging downwards along the inner wall of the baffle plate 64. The airflow then passes uniformly through the perforated plate 65, reducing turbulence and velocity, and uniformly impacts the blocking protrusions 9 on the surface of the impact plate 66. Rigid impact causes medium-sized oil droplets to adhere and separate. The airflow is further deflected and slowed by the blocking block 141 of the auxiliary separation device 14, extending the gas residence time. The remaining fine oil droplets are then deeply adsorbed by the second oil-resistant polyurethane sponge block 143 wrapped in a wire mesh bag 142. The airflow after impact and diversion flows through the ventilation holes 10 around the impact plate 66. The first oil-resistant polyurethane sponge blocks 610 on both sides capture suspended fine oil droplets in the airflow through their porous adsorption structure. The airflow continues to flow backwards, completing multi-stage composite oil-gas separation. Simultaneously, the first and second oil-resistant polyurethane sponge blocks 610 effectively adsorb other impurities in the gas, ensuring the service life of the engine oil.

[0042] The liquid engine oil separated from each stage of the structure is uniformly collected along the inner wall of the cavity to the bottom oil outlet 67. It is then transported downward through the connecting channel 681 and flows out evenly and slowly from multiple sets of oil outlet holes 683 at the oil outlet 682. After being buffered and guided by the blowout preventer 684, it falls smoothly into the oil storage chamber 2, effectively preventing oil backflow from directly hitting the liquid surface and causing oil splashing and secondary oil vapor generation. At the same time, the blowout preventer 684 can prevent the original oil vapor inside the oil storage chamber 2 from flowing back into the oil-gas separation chamber, ensuring stable separation efficiency. The clean gas after separation and purification finally flows through the pressure adaptive PCV valve 19 at the outlet 69, which automatically adjusts the opening according to the engine operating conditions, sending the clean gas into the engine intake manifold for combustion.

[0043] The entire unit adopts a dual-circuit pressure coordination regulation mode. Under normal idling and low-load conditions, the intake manifold vacuum is stable, and the pressure adaptive PCV valve 19 dominates the pressure regulation, maintaining a stable slight negative pressure in the cavity, while the parallel two-way pressure valve PCV group 8 remains closed. Under high engine speed and heavy load conditions, the crankcase blow-by volume increases and the cavity pressure rises. When the set positive pressure threshold is reached, the reverse pressure relief valve PCV unit inside the two-way pressure valve PCV group automatically opens, and clean gas in the cavity is delivered to the clean side of the air filter through the air inlet 7 and the valve PCV group pipeline, realizing closed-loop air outlet pressure relief, balancing the internal pressure of the cavity, and preventing oil leakage and oil vapor overflow. Under conditions of rapid vehicle deceleration and coasting, the intake manifold vacuum rises sharply, and the cavity negative pressure exceeds the limit. The positive air inlet valve unit of the parallel two-way pressure valve group 8 opens, and clean air is introduced from the clean side of the air filter to balance the negative pressure and avoid oil seal collapse and electronic oil pump 4 suction failure.

[0044] During operation, the electronic level sensor 20, temperature sensor 22, and water content sensor 23 dynamically collect oil level, operating temperature, and water content parameters in real time and transmit them to the controller 21. The controller 21 performs real-time data analysis and logical judgment, and outputs early warning signals in a timely manner under abnormal conditions, realizing intelligent monitoring of oil status. During maintenance, oil can be added through the filler port 11, and waste oil can be completely drained from the bottom drain hole 17 by unscrewing the drain plug 18. The entire process of operation, adjustment, monitoring, and maintenance is continuous and reliable.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the scope of the invention.
