Description

Technical Field

[0001] This invention belongs to the technical field of online oil monitoring technology, specifically relating to an online defoaming device based on the principles of oil fluid characteristics and data cleaning algorithms. Background Technology

[0002] It is unavoidable for lubricating oil to generate air bubbles during circulation. Similarly, during online oil monitoring and sampling, oil samples containing air bubbles will inevitably be collected. The presence of air bubbles will cause deviations in the sensor during sampling and processing, resulting in inaccurate analysis data, false alarms, and an inability to accurately reflect the operating status of the equipment.

[0003] Current research on methods for eliminating air bubbles in lubricating oil during use mostly employs physical methods to remove bubbles from the oil, such as the vibration method: using mechanical or acoustic vibration to detach bubbles from the liquid. Vibration increases the relative velocity between the bubbles and the liquid, thus causing the bubbles to detach. This method is suitable for smaller bubbles.

[0004] It is understood that defoaming technology is already being used in online oil monitoring systems, as follows:

[0005] The working principle of the hydraulic oil online monitoring and defoaming device is shown in the figure below. Hydraulic oil is injected into a sealed defoaming tank after being stabilized, slowed, and allowed to settle through a metal coil. When the level sensor in the defoaming tank detects that the injected hydraulic oil has reached the specified level, the inlet is closed and the defoaming tank is sealed. The oil in the tank is pressurized, evacuated, and vented to eliminate tiny air bubbles mixed in with the hydraulic oil. Finally, the defoamed hydraulic oil is sent to a particle size sensor for monitoring, as shown in the attached diagram of the instruction manual. Figure 1 The diagram shows the design of an online hydraulic oil monitoring and defoaming device.

[0006] However, traditional devices still have the following problems when in use:

[0007] The problems and drawbacks of the above-mentioned physical defoaming methods are that additional defoaming devices need to be deployed on-site. The addition of these devices increases the inspection workload for equipment operators and maintenance personnel, and also increases the equipment management workload for managers.

[0008] Since online oil monitoring systems are miniaturized, integrated, and precision devices, the amount of oil sample collected and analyzed at one time is relatively small. Air bubbles in the oil can have a significant impact on the data analysis process. How to eliminate air bubbles in the sampling process of online oil monitoring systems without adding external defoaming equipment has become a challenge in the industry. Summary of the Invention

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0038] Please see Figures 2 to 14 This invention provides a technical solution: an online defoaming device based on the principle of oil fluid characteristics and a data cleaning algorithm, comprising a pump station frame 1, an oil tank 2 fixedly installed on one inner wall of the pump station frame 1, a central control system operating console 3 fixedly connected to one outer wall of the oil tank 2, a chassis 4 fixedly connected to one outer wall of the oil tank 2, a flow pipeline 5 provided on one outer wall of the oil tank 2, multiple flow pumps provided in the flow path of the flow pipeline 5, each of the multiple flow pumps having a data sensor installed inside, the data sensor being electrically connected to the central control system operating console 3, a flat-welded flange 6 fixedly connected to the outer wall of the flow pipeline 5, and the flow pipeline 5 being fixedly connected to the input end of the oil tank 2 through the flat-welded flange 6, wherein the flow of the flow pipeline 5... An online sampling mechanism is set in the middle of the path. A pipeline data construction mechanism is set on the outer wall of the pump station frame 1. The pipeline data construction mechanism includes a permanent magnetic adsorption roller 41, an orientation adjustment bracket 42, and a three-dimensional scanner 43. A magnetically conductive material wall surface 44 is installed on the top outer wall of the pump station frame 1. An orientation adjustment bracket 42 is set on the bottom outer wall of the magnetically conductive material wall surface 44. The outer wall of the permanent magnetic adsorption roller 41 is fixedly installed with the outer wall of the orientation adjustment bracket 42. The outer wall of the permanent magnetic adsorption roller 41 is magnetically adsorbed and connected to the bottom outer wall of the magnetically conductive material wall surface 44. The outer wall of the three-dimensional scanner 43 is fixedly connected to the outer wall of the orientation adjustment bracket 42. The three-dimensional scanner 43 is connected to the data signal of the central control system operating console 3.

[0039] In this invention, the central control system console 3 is equipped with a pipeline data construction mechanism. The mechanism is attached to a magnetically conductive material wall 44 by a permanent magnetic adsorption roller 41, allowing it to move. By utilizing the movement of the permanent magnetic adsorption roller 41 and the position adjustment bracket 42, the 3D scanner 43 can perform 3D scanning of the pipeline from multiple angles, thus constructing a 3D model of the current pipeline. This device, combined with the data processing of the central control system console 3, enables personnel to conduct research on lubricating oil fluid dynamics. By analyzing the fluid dynamic behavior of lubricating oil in the pipeline, key parameters such as the thickness of the lubricating oil film, pressure distribution, and flow velocity can be calculated. A fluid motion model of lubricating oil under different environmental pressures, flow velocities, and viscosities in the pipeline can be established to optimize the delivery efficiency and uniformity of the lubricating oil. To ensure uniform performance, an optimal flow path is designed based on different bends and parameter variations in the pipeline, minimizing air bubbles in the lubricating oil. Pressure regulation by each flow pump further eliminates air bubbles. The central control system console 3 is equipped with an intelligent AI algorithm and monitors lubricating oil flow data in each flow pump via data sensors. This technology combines intelligent AI algorithms with manual algorithms for data acquisition, processing and refining oil data indicators to suit analysis and modeling. A data cleaning algorithm is established, and data cleaning strategies, including manual and automatic cleaning strategies, are developed and combined with other strategies to identify and clean abnormal data affecting the collected data, improving data accuracy and reliability. Example 2

[0040] Based on Embodiment 1, the online sampling mechanism includes a collection pump 7, a shaft support 9, a connecting bearing 10, a specially made inner bearing sleeve 11, a control turntable 12, a sampling tube 13, and a limiting rack 14. The inner wall of the collection pump 7 is connected to the flow path of the flow pipeline 5. The top outer wall of the shaft support 9 is connected to the inner wall of the collection pump 7. The four outer walls of the connecting bearing 10 are fixedly connected to the inner wall of the shaft support 9. The bottom side of the four outer walls of the specially made inner bearing sleeve 11 is hinged to the inner wall of the connecting bearing 10. The inner wall of the specially made inner bearing sleeve 11 has an internal thread groove. Two limiting racks 14 are provided. The outer walls of the two limiting racks 14 are fixedly connected to the two outer walls of the sampling tube 13. The outer walls of the two limiting racks 14 are threadedly connected to the inner wall of the internal thread groove. A limiting block 33 is fixedly connected to the bottom outer wall of the connecting bearing 10. A groove 34 is provided on one side of the outer wall of the position block 33. The inner wall of the groove 34 is slidably connected to the outer wall of the limiting rack 14. A liquid oil sedimentation tank 8 is provided on the bottom inner wall of the collecting pump 7. The sampling tube 13 is connected to the interior of the liquid oil sedimentation tank 8 through the collecting pump 7. An antifoaming agent carrying tank 16 is provided inside the sampling tube 13. An output valve 22 connected to the outer wall of the sampling tube 13 is fixedly installed on the inner wall of the antifoaming agent carrying tank 16. A bottle stopper 2 19 is movably connected to the top outer wall of the sampling tube 13. A dosage replenishment tube 20 connected to the interior of the antifoaming agent carrying tank 16 and a one-way exhaust valve 21 are provided on the top outer wall of the bottle stopper 2 19. A bottle stopper 17 is movably connected to the top outer wall of the sampling tube 13. A one-way exhaust valve 18 connected to the interior of the liquid oil sampling tank 15 is provided on the top outer wall of the bottle stopper 17.

[0041] When staff need to take samples of liquid oil for inspection and monitoring, the sampling tube 13 is placed inside the specially designed inner bearing sleeve 11. After the limiting racks 14 on both sides of the sampling tube 13 are engaged in the sliding grooves 34, the staff can rotate the control turntable 12 to drive the specially designed inner bearing sleeve 11 to rotate. Due to the limiting block 33, the threaded rotation of the specially designed inner bearing sleeve 11 causes the sampling tube 13 to move vertically. This device can pump the sampling tube 13 into the collection pump 7 to collect the liquid oil flowing in the collection pump 7. A liquid oil sedimentation tank 8 is set on the inner wall at the bottom of the collection pump 7. A settling zone can be formed, allowing some oil residue and waste in the passing liquid oil to fall into the liquid oil sedimentation tank 8, facilitating the regular collection and discharge of oil residue and waste by staff. This also makes the liquid oil in the subsequent pipeline purer and improves the accuracy of liquid oil data monitoring. By setting up an antifoaming agent carrier tank 16 and an output valve 22, this invention can serve as a physical data measurement mechanism to meet the online sampling of liquid oil, and can also be used as a pumping device to reduce the generation of bubbles at the collection pump 7 when chemical intervention is required by injecting antifoaming agent into the antifoaming agent carrier tank 16. This satisfies multiple solutions to the defoaming problem. Example 3

[0042] Based on Embodiment 1, the sampling tube 13 has an internal oil sampling groove 15. A support block 23 is fixedly connected to the bottom outer wall of the sampling tube 13. The bottom outer wall of the support block 23 has an installation groove 24 that communicates with the oil sampling groove 15. A limiting tube 25 is movably connected to the inner wall of the installation groove 24. An anti-detachment connecting ring 26 is fixedly connected to the top outer wall of the limiting tube 25. Sampling channels 28 are provided on the outer walls of both the support block 23 and the limiting tube 25. The sampling channels 28 are streamlined and curved. The inner wall of the sampling channels 28 is connected to the inner wall of the oil sampling groove 15 through the limiting tube 25. An indentation groove 27 is provided on the outer wall of the support block 23. The indentation groove 27 is a perfect conical shape. The sampling tube 13 has an inverted conical shape at the bottom outer wall. The bottom outer wall of the limiting tube 25 is fixedly connected to a threaded connector 29. The outer wall of the threaded connector 29 is provided with a one-way anti-detachment bearing sleeve 30. The inner wall of the inner bushing of the one-way anti-detachment bearing sleeve 30 is provided with an internal thread. The threaded connector 29 is threadedly connected to the inner bushing of the one-way anti-detachment bearing sleeve 30. The outer wall of the one-way anti-detachment bearing sleeve 30 is fixedly connected to a defoaming fan blade 31. The rotation circumference of the defoaming fan blade 31 is equal to the circumference of the bottom outer wall of the support block 23. The bottom outer wall of the one-way anti-detachment bearing sleeve 30 is fixedly connected to an anti-slip pad 32. The bottom outer wall of the anti-slip pad 32 is movably connected to the bottom inner wall of the liquid oil sedimentation tank 8.

[0043] In this invention, after the sampling tube 13 is placed into the collecting pump 7, the defoaming fan blade 31 at the bottom of the support block 23 will be the first to enter the liquid surface. The defoaming fan blade 31 has a certain inclined surface, and the downward resistance in the liquid oil will drive the defoaming fan blade 31 to rotate slowly. In this way, the air bubbles that may be contained in the liquid oil at the bottom of the support block 23 can be effectively discharged to the surrounding area. The rotation circumference of the defoaming fan blade 31 is equal to the circumference of the bottom outer wall of the support block 23, and the liquid oil pressure at the bottom of the liquid oil sedimentation tank 8 is relatively higher than that at the surface, so the air bubbles will... As buoyancy directly discharges to the surface of the liquid oil, the conical recessed groove 27 of this invention prevents the inlet of the sampling channel 28 from contacting rising air bubbles, thus ensuring that the liquid oil sample is bubble-free and guaranteeing the accuracy of the sample data. Furthermore, the streamlined curved sampling channel 28 of this invention minimizes liquid oil collisions as it enters the liquid oil sampling tank 15, thereby reducing air bubbles generated by these collisions and further improving the accuracy of the sampling data. The anti-slip pad 32 increases friction... During the downward movement of the sampling tube 13, the limiting tube 25 rotates at a certain angle to prevent the sampling channel 28 from communicating with the oil sampling tank 15. Furthermore, the one-way anti-detachment bearing sleeve 30 can only rotate in one direction. The steering force applied by the one-way anti-detachment bearing sleeve 30 further improves the closure of the limiting tube 25. When the anti-slip pad 32 touches the bottom, the further downward pressure of the sampling tube 13 causes the threaded connector 29 to rotate within the inner thread of the one-way anti-detachment bearing sleeve 30, causing the limiting tube 25 to deflect, allowing the sampling channel 28 to communicate with the oil sampling tank 15. The sampling tank 15 is connected for sampling. Since the sampling tube 13 is higher than the liquid level of the collection pump 7 in this invention, sufficient liquid oil can be drawn through the sampling tube 13 by natural flow without overflowing. After the sampling is completed, the operator rotates the control turntable 12 in reverse to move the sampling tube 13 upward. At this time, the natural gravity of the one-way anti-detachment bearing sleeve 30 and the defoaming fan blade 31 causes the limiting tube 25 to rotate and re-close the connection of the sampling channel 28, thereby preventing liquid oil leakage. Example 4

[0044] Based on Embodiment 2, limit bearings 35 are provided on both sides of the outer wall of the two limit blocks 33. The outer bushing of the limit bearing 35 is fixedly connected to the outer wall of the limit block 33. The inner bushing of the limit block 33 is fixedly connected to the fixing block 36. The outer wall of the fixing block 36 on the opposite side of the two limit blocks 33 is fixedly connected to the same flexible connecting rope 37. The outer wall of the flexible connecting rope 37 is fixedly connected to the wiping sponge sleeve 38. The outer wall of the wiping sponge sleeve 38 is movably connected to the outer wall of the sampling tube 13. The top inner wall of the collection pump 7 is fixedly connected to the mounting bracket 39. The inner wall of the mounting bracket 39 is fixedly installed with a visual monitoring camera probe 40. The visual monitoring camera probe 40 is electrically connected to the central control system operating console 3.

[0045] In this invention, during the upward movement of the sampling tube 13, the wiping sponge sleeve 38 can slide along the outer wall of the sampling tube 13 to wipe the liquid oil on the outer wall of the sampling tube 13. After the sampling tube 13 is pulled out, the flexible connecting rope 37 hangs down slightly, causing the wiping sponge sleeve 38 to float on the surface of the liquid oil in the collection pump 7. This allows the wiping sponge sleeve 38 to block any air bubbles that may be present on the oil surface in the flow pipeline 5, achieving stagnation and defoaming. This invention also uses a visual monitoring camera probe 40 to capture images of the air bubbles in the collection pump 7 and feed the data back to the central control system console 3, thereby determining the air bubble content in the lubricating oil in the pipeline and performing data monitoring.

[0046] The working principle and usage process of this invention: In this invention, the central control system operating console 3 is equipped with a pipeline data construction mechanism. The mechanism is attached to the magnetically conductive material wall 44 by a permanent magnetic adsorption roller 41 and moves accordingly. Utilizing the movement of the permanent magnetic adsorption roller 41 and the position adjustment bracket 42, the 3D scanner 43 can perform 3D scanning of the pipeline from multiple angles, thus constructing a 3D model of the current pipeline. This device, combined with the data processing of the central control system operating console 3, allows operators to conduct research on lubricating oil fluid dynamics. By analyzing the fluid dynamic behavior of lubricating oil in the pipeline, key parameters such as the thickness of the lubricating oil film, pressure distribution, and flow velocity can be calculated, establishing the model of lubricating oil in the pipeline. This technology employs fluid motion models of lubricating oil under varying environmental pressures, flow velocities, and viscosities within pipelines to optimize delivery efficiency and uniformity. Based on different bends and parameter variations in the pipeline, optimal flow paths are designed to minimize air bubbles in the lubricating oil. Pressure regulation at each flow pump further eliminates air bubbles. The central control system's console 3 incorporates intelligent AI algorithms and monitors lubricating oil flow data at each flow pump via data sensors. This technology combines intelligent AI algorithms with manual algorithms for data acquisition, processing and refining oil data indicators to suit analysis and modeling. A data cleaning algorithm is also established. The system employs data cleaning strategies, including manual and automated cleaning, combined with other strategies, to identify and clean the impact of abnormal data on the collected data, thereby improving the accuracy and reliability of the data. When staff need to take samples of liquid oil for inspection and monitoring, the sampling tube 13 is placed inside the specially designed inner bearing sleeve 11. Once the limiting racks 14 on both sides of the sampling tube 13 are engaged in the sliding grooves 34, the staff can rotate the control turntable 12 to drive the specially designed inner bearing sleeve 11 to rotate. Due to the limiting block 33, the threaded rotation of the specially designed inner bearing sleeve 11 allows the sampling tube 13 to move vertically. This device allows the sampling tube 13 to be pumped into the collection pump 7 for further processing. The liquid oil flowing in the collecting pump 7 is collected. By setting a liquid oil sedimentation tank 8 on the bottom inner wall of the collecting pump 7, a sedimentation zone can be formed, allowing some oil residue and waste in the passing liquid oil to fall into the liquid oil sedimentation tank 8. This makes it convenient for staff to collect and discharge the oil residue and waste regularly, and makes the liquid oil in the subsequent pipeline purer, improving the accuracy of liquid oil data monitoring. By setting an antifoaming agent carrier tank 16 and an output valve 22, this invention can not only serve as a physical data measurement mechanism to meet the online sampling of liquid oil, but also, when chemical intervention is required, inject antifoaming agent into the antifoaming agent carrier tank 16 to mix and act as a pump pressure device to reduce the generation of bubbles at the collecting pump 7 position, thus meeting multiple solutions to the defoaming problem.In this invention, after the sampling tube 13 is placed into the collecting pump 7, the defoaming fan blade 31 at the bottom of the support block 23 will be the first to enter the liquid surface. The defoaming fan blade 31 has a certain inclined surface, and the downward resistance in the liquid oil will drive the defoaming fan blade 31 to rotate slowly. In this way, the air bubbles that may be contained in the liquid oil at the bottom of the support block 23 can be effectively discharged to the surrounding area. The rotation circumference of the defoaming fan blade 31 is equal to the circumference of the bottom outer wall of the support block 23, and the liquid oil pressure at the bottom of the liquid oil sedimentation tank 8 is relatively higher than that at the surface. Therefore, the air bubbles will be directly discharged to the surface of the liquid oil by buoyancy. Combined with the conical recessed groove 27 set in this invention, the inlet of the sampling channel 28 cannot come into contact with the rising air bubbles. This design ensures that the liquid oil sample is free of air bubbles, guaranteeing the accuracy of the sample data. Furthermore, the streamlined, curved sampling channel 28 minimizes collisions between the liquid oil and the sample tank 15, reducing air bubbles and further improving data accuracy. The anti-slip pad 32 increases friction, and as the sampling tube 13 descends, the limiting tube 25 rotates at a certain angle to prevent communication between the sampling channel 28 and the sample tank 15. The one-way anti-detachment bearing sleeve 30 can only rotate in one direction, and the steering force applied by the one-way anti-detachment bearing sleeve 30 further improves the closure of the limiting tube 25. When the anti-slip pad 32 touches the bottom… Further downward pressure on the sampling tube 13 causes the threaded connector 29 to rotate within the inner thread of the one-way anti-detachment bearing sleeve 30, thereby deflecting the limiting tube 25. This allows the sampling channel 28 to connect with the liquid oil sampling tank 15 for sampling. Since the sampling tube 13 is higher than the liquid level of the collecting pump 7, sufficient liquid oil can be extracted through natural flow without overflow. After extraction, the operator reverses the rotation of the turntable 12 to move the sampling tube 13 upward. At this point, the natural gravity of the one-way anti-detachment bearing sleeve 30 and the defoaming fan blade 31 causes the limiting tube 25 to rotate, reclosing the sampling channel 28. The connection is designed to prevent oil leakage. In this invention, during the upward movement of the sampling tube 13, the wiping sponge sleeve 38 can slide along the outer wall of the sampling tube 13 to wipe the oil on the outer wall. After the sampling tube 13 is pulled out, the flexible connecting rope 37 droops slightly, causing the wiping sponge sleeve 38 to float on the surface of the oil in the collecting pump 7. This allows the wiping sponge sleeve 38 to block any air bubbles that may be present on the oil surface in the flow pipeline 5, achieving defoaming. This invention also uses a visual monitoring camera probe 40 to capture images of the air bubbles in the collecting pump 7 and feed the data back to the central control system console 3, thereby determining the air bubble content in the lubricating oil in the pipeline and monitoring the data.
