Description

Technical Field

[0001] This utility model relates to the field of lubricating oil monitoring technology, specifically to a lubricating oil monitoring device that integrates multi-parameter monitoring and intelligent analysis. Background Technology

[0002] Lubricating oil plays an indispensable role in the operation of mechanical equipment, and its performance directly affects the normal operation and service life of the equipment. Lubricating oil monitoring devices can monitor the condition of the lubricating oil, promptly detect wear on internal components of mechanical equipment, and provide early warnings of potential faults. Existing lubricating oil monitoring devices mainly include atomic emission spectrometers, infrared spectrometers, and ferrometers. From a working principle perspective, atomic emission spectrometers introduce a lubricating oil sample into an excitation source, causing metal atoms to transition and emit light of specific wavelengths; the concentration of metal elements is determined through spectral analysis and detection. Infrared spectrometers utilize the absorption characteristics of infrared light by molecules in lubricating oil, converting changes in transmitted light intensity into a spectral image for analysis. Ferrometers, on the other hand, observe and analyze abrasive particles deposited on a substrate under the influence of a magnetic field.

[0003] Existing lubricating oil monitoring devices have the following shortcomings:

[0004] 1. Existing monitoring devices have limited monitoring parameters, focusing only on a few key indicators such as viscosity and pH. These parameters cannot comprehensively reflect the overall condition of the lubricating oil, making it difficult to accurately assess the overall operating status of the equipment.

[0005] 2. Some monitoring devices heavily rely on specialized knowledge. Operators must not only have a deep understanding of complex chemical analysis principles and be proficient in instrument calibration methods, but also maintain constant operational precision. In practice, any minor operational error, such as slight deviations during calibration or improper sample collection, can lead to serious deviations in monitoring data, affecting the assessment of the equipment's condition.

[0006] 3. When faced with massive amounts of monitoring data, the monitoring device lacks effective data mining algorithms, making it difficult to extract patterns of lubricant performance changes from historical data, and also unable to use machine learning and other technologies to scientifically predict future oil conditions, resulting in delays in equipment maintenance.

It solves the technical problems of existing monitoring devices, such as hardware redundancy caused by relying on multiple independent sensors, single monitoring parameters, focusing only on a few key indicators, inability to comprehensively reflect the overall condition of the lubricating oil, and difficulty in making accurate judgments on the overall operating status of the equipment.

[0009] (II) Technical Solution

[0010] This utility model provides the following technical solution: a lubricating oil monitoring device integrating multi-parameter monitoring and intelligent analysis, including a housing and a monitoring module disposed within the housing. The monitoring module includes a monitoring inlet pipe, an inlet electric ball valve, a micro pump, an oil condition sensor, an oil particle counter, an oil metal abrasive sensor, an outlet electric ball valve, and a monitoring outlet pipe. The monitoring inlet pipe, the inlet electric ball valve, the oil condition sensor, the micro pump, the oil metal abrasive sensor, the outlet electric ball valve, and the monitoring outlet pipe are connected sequentially through pipelines. A first tee connector is provided between the inlet electric ball valve and the oil condition sensor, and a second tee connector is provided between the micro pump and the oil condition sensor. One end of the first tee connector and one end of the second tee connector are connected to the oil particle counter.

[0011] Preferably, the housing includes a front shell and a rear shell, which are connected by a hinge. The front shell has a display screen, an emergency stop switch, a warning light and a power button on its front side, a processor and a waterproof connector on its inner side, and a buzzer, a lock and a handle on its side. The monitoring module is located inside the rear shell.

[0013] Preferably, the inlet electric ball valve, micro pump, oil condition sensor, oil particle counter, oil metal abrasive sensor, and outlet electric ball valve are fixedly connected to the rear housing via a bracket.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a lubricating oil monitoring device that integrates multi-parameter monitoring and intelligent analysis, which has the following beneficial effects:

[0016] 1. By setting up an oil condition sensor, the physical and chemical properties of the oil, as well as impurities, can be monitored. This allows for a precise understanding of the overall condition of the lubricating oil, a comprehensive understanding of the wear of internal components and changes in lubrication performance, and thus more accurately provides early warnings of potential faults. Furthermore, a single sensor can simultaneously monitor eight physical and chemical parameters, significantly reducing hardware complexity and space requirements, and improving data acquisition efficiency.

[0017] 2. By comprehensively analyzing oil monitoring parameters, it is possible to more accurately determine whether metal debris has entered the lubricating oil due to excessive wear of a certain part of the equipment, thereby affecting the chemical and physical properties of the lubricating oil, rather than making a one-sided judgment based on a single parameter. This is of great significance for taking timely and effective maintenance measures and ensuring the normal operation of the equipment.

[0018] 3. This monitoring device is simple to operate; ordinary operators can learn to use it after simple training. In the daily maintenance of industrial machinery, operators do not need professional knowledge to easily use the lubrication monitoring device to check the lubrication system of the equipment, reducing reliance on professional technicians and improving the convenience and timeliness of the inspection.

[0019] 4. The monitoring device has a simple structure and a low probability of failure. Furthermore, when equipment malfunctions, maintenance personnel can more easily troubleshoot the cause, simplifying the repair process. This reduces equipment maintenance costs and downtime due to equipment failure, effectively improving production efficiency and minimizing economic losses caused by lubrication issues.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a lubricating oil monitoring device that integrates multi-parameter monitoring and intelligent analysis.

[0028] Please see Figure 1-4 A lubricating oil monitoring device integrating multi-parameter monitoring and intelligent analysis includes a housing 10 and a monitoring module 1 disposed within the housing. The monitoring module 1 includes a monitoring inlet pipe 11, an inlet electric ball valve 12, a micro pump 13, an oil condition sensor 14, an oil particle counter 15, an oil metal abrasive sensor 16, an outlet electric ball valve 17, and a monitoring outlet pipe 18. The monitoring inlet pipe 11, the inlet electric ball valve 12, the oil condition sensor 14, the micro pump 13, the oil metal abrasive sensor 16, the outlet electric ball valve 17, and the monitoring outlet pipe 18 are connected sequentially by pipes. A first tee connector 19 is provided between the inlet electric ball valve 12 and the oil condition sensor 14, and a second tee connector 110 is provided between the micro pump 13 and the oil condition sensor 14. One end of the first tee connector 19 and one end of the second tee connector 110 are connected to the oil particle counter 15.

[0029] The present invention relates to a lubricating oil monitoring device that integrates multi-parameter monitoring and intelligent analysis. The oil inlet and outlet of the monitoring module 1 are located on the right side of the outer casing and are connected to the monitoring oil inlet pipe 11 and the monitoring oil outlet pipe 18, respectively.

[0030] The monitoring module 1 mainly includes a monitoring inlet pipe 11, an inlet electric ball valve 12, a micro pump 13, an oil condition sensor 14, an oil particle counter 15, an oil metal abrasive sensor 16, an outlet electric ball valve 17, and a monitoring outlet pipe 18, as well as a display screen and a main control board. The oil condition sensor 14 primarily uses piezoelectric resonant MEMS elements, integrating high-precision signals and processing units, combined with built-in algorithms, to automatically detect eight indicators in real time: temperature, kinematic viscosity, density, dielectric constant, water activity, water content, and dynamic viscosity. The oil particle counter 15 uses a light-shielding method, employing a laser emitter and a photoelectric receiver to determine the particle size and the number of particles per unit volume of oil sample. The oil particle counter 15 incorporates multiple particle contamination level standards and provides the particle count and contamination level of the measured sample in real time. The oil metal abrasive sensor 16 adopts the principle of electromagnetic induction and has a built-in excitation coil and induction coil. When metal abrasive particles pass through the sensor, it can complete the real-time capture and reporting of metal abrasive particle signals and detect the size and quantity of metal particles in a timely manner.

[0031] In a preferred embodiment, refer to Figure 1 and Figure 2 The housing 10 of the lubricating oil monitoring device integrating multi-parameter monitoring and intelligent analysis includes a front housing 101 and a rear housing 102, which are connected by a hinge 103. The front housing 101 has a display screen 104, an emergency stop switch 105, a warning light 106, and a power button 107 on its front side, a processor 108 and a waterproof connector 109 on its inner side, and a buzzer 1010, a lock 1011, and a handle 1012 on its side. The monitoring module 1 is located inside the rear housing 102. The rear housing 102 has a power interface 1013, a communication interface 1014, and a handle 1015 on its side, and a shock-absorbing bracket 1016 on its rear side.

[0032] Specifically, the front shell 101 and the rear shell 102 constitute the outer casing 10 of the monitoring device. Two hinges 103 are provided, respectively located between the front shell 101 and the rear shell 102, to open and close the casing. The display screen 104 displays the monitored real-time data. The emergency stop switch 105 is used in emergencies to quickly power off and shut down the monitoring device. When a fault occurs, the warning light 106 illuminates red to serve as a warning, and the buzzer 1010 also sounds an alarm. The power button 107 is used to turn the monitoring device on / off. The processor 108... Used for processing and storing collected data; waterproof connector 109 prevents moisture from entering the internal processor 108 by clamping external cables; lock 1011 is used to lock the front shell 101 and the rear shell 102; handle 1012 facilitates opening the front shell 101; power interface 1013 is used to connect an external power source to power the monitoring device; communication interface 1014 transmits data to other devices via an external data cable; handle 1015 facilitates carrying and transporting the device; shock-absorbing bracket 1016 facilitates fixing the monitoring device to a wall or other device.

[0033] In a preferred embodiment, refer to Figure 2 and Figure 3 The inlet electric ball valve 12, micro pump 13, oil condition sensor 14, oil particle counter 15, oil metal abrasive sensor 16, and outlet electric ball valve 17 of the lubricating oil monitoring device integrating multi-parameter monitoring and intelligent analysis are fixedly connected to the rear housing 102 via a bracket 1017. The bracket 1017 is fixed to the rear housing 102 to ensure the stability of the installation of each component.

[0034] The flow process of the lubricating oil in this utility model's integrated multi-parameter monitoring and intelligent analysis lubricating oil monitoring device is as follows:

[0035] After the equipment is powered on, the oil inlet electric ball valve 12 opens automatically, and the micro pump 13 provides power. The oil flows along the monitoring oil inlet pipe 11 to the first three-way connector 19, and then splits into two paths. One path passes through the oil status sensor 14, and the other path passes through the oil particle counter 15. Then they converge at the second three-way connector 110, pass through the micro pump 13, and then flow through the oil metal abrasive sensor 16. Finally, the oil flows out from the monitoring oil outlet pipe 18, thus completing the oil circulation.

[0036] Furthermore, the power interface 1013 is connected to an external 220V 50Hz single-phase power supply. The device is powered on by pressing the power button 107, at which point the display screen 104 lights up. All real-time monitoring data is displayed on the screen 104, including temperature, kinematic viscosity, density, dielectric constant, water activity, water content, water percentage, and dynamic viscosity detected by the 8-in-1 oil condition sensor 14; the number of metal abrasive particles detected by the oil metal abrasive sensor 16; and the number of particles and contamination level detected by the oil particle counter 15. Threshold settings, data viewing, and data export can be performed by touching the display screen.

[0037] After the sensor collects relevant data, it transmits it to the processor 108 for data processing and storage. The data is then transmitted to the host computer for edge preprocessing (such as noise reduction using an improved Kalman filter and feature compression transmission). Since changes in various oil parameters affect the oil's condition, and the coupling effect between parameters can increase the probability of equipment failure, it is necessary to perform weighted fusion of multiple oil parameters to dynamically reflect the overall degree of oil degradation, fit an oil condition degradation curve, identify accelerated degradation inflection points, and perform feature mapping on typical faults. Finally, a life prediction model is constructed by combining all operating parameters, ambient temperature, and usage time. This model infers the degree of wear or performance degradation and potential faults in the next oil condition period by referring to historical oil condition records. A warning threshold is set based on the changing trend of the oil condition parameters. When the monitored data exceeds the threshold, the warning light 106 illuminates, and the buzzer 1010 sounds, thus achieving an alarm effect.

[0038] In summary, monitoring module 1 collects oil quality data and transmits it to the host computer. Using algorithms such as deep learning, it mines and analyzes the large amount of data, weights and fuses different parameters, fits a degradation curve, performs feature mapping on typical faults, and finally constructs a life prediction model to predict future performance changes of the oil. All monitoring data is displayed on the screen, and functions such as threshold setting and data export are also operated on the screen.

[0039] The lubricating oil monitoring device of this invention, which integrates multi-parameter monitoring and intelligent analysis, also has the following characteristics:

[0040] 1. The traditional, dispersed monitoring modules are integrated into a highly integrated eight-in-one sensor. Through microelectromechanical systems (MEMS) technology, a single sensor can simultaneously capture the physical properties and chemical state of lubricating oil, including key parameters such as temperature, viscosity, and dielectric constant. This solves the hardware redundancy problem caused by traditional equipment relying on multiple independent sensors. The multi-module collaborative design further enables full-spectrum analysis of contaminant size and material, accurately identifying everything from micron-sized non-metallic particles to millimeter-sized metal abrasive particles.

[0041] 2. The equipment's human-machine interface abandons traditional mechanical buttons and complex menus, adopting an intuitive touchscreen design that supports dynamic threshold adjustment and multi-dimensional data visualization. The interaction logic revolves around "one-click operation," allowing even non-professionals to quickly grasp the status assessment and alarm response process.

[0042] 3. The piping system adopts standardized stainless steel components and a compression fitting design, balancing corrosion resistance with the need for quick assembly and disassembly. The outer casing structure utilizes reinforced sheet metal processing and surface coating technology to achieve a compact layout of sensors and pump / valve components within a limited space. Modular design further lowers the maintenance threshold; most components use industry-standard interfaces, supporting rapid on-site replacement and significantly reducing equipment downtime.

[0043] 4. Employing big data analytics, we collect a large amount of lubricating oil physicochemical data and use machine learning, deep learning, and other algorithms to mine the data, thereby constructing an oil condition model to achieve equipment failure prediction and lubricating oil life assessment.

[0044] 5. Monitoring of multiple oil condition parameters covers physical properties, chemical properties, and impurities, enabling precise control of the overall condition of the lubricating oil, comprehensive understanding of the wear of internal components and changes in lubrication performance, thus providing more accurate early warning of potential faults. Furthermore, a single sensor enables simultaneous monitoring of 8 physical and chemical parameters, significantly reducing hardware complexity and space occupation, and improving data acquisition efficiency.

[0045] 6. Data analysis helps to more accurately determine the type and cause of equipment failure. For example, when an increase in the metal particle content in lubricating oil is detected, coupled with a decrease in viscosity, comprehensive analysis of these parameters can more accurately determine whether excessive wear of a certain component of the equipment has led to metal debris entering the lubricating oil, thus affecting its chemical and physical properties. This is more accurate than relying on a single parameter for a one-sided judgment, which is crucial for timely and effective maintenance and ensuring the normal operation of equipment. Dynamic models and predictive capabilities enable a technological leap from "monitoring" to "prediction," filling the gap in analytical depth in existing technologies.

[0046] 7. Existing monitoring devices, such as atomic emission spectrometers and infrared spectrometers, are complex to operate and highly dependent on specialized personnel. In contrast, existing monitoring devices are simple to operate; ordinary operators can learn to operate them after simple training. In the daily maintenance of industrial machinery, operators do not need specialized knowledge to easily use lubrication monitoring devices to check the lubrication system of equipment, reducing reliance on specialized technicians and improving the convenience and timeliness of testing.

[0047] 8. The equipment has a simple structure and a low probability of failure. Furthermore, when problems do occur, maintenance personnel can more easily troubleshoot the cause, simplifying the repair process and reducing maintenance costs and downtime due to equipment malfunctions. For large industrial machinery, this effectively improves production efficiency and reduces economic losses caused by lubrication issues.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
