Description

Technical Field

[0001] The present application relates to the technical field of oil monitoring, and in particular to an online oil monitoring device for oil circuits with large diameters and a wide flow rate range. Background Art

[0002] In large-diameter lubricating oil systems in mining, wind, thermal, and hydropower generation, large-scale engineering machinery and equipment, transportation vehicles, aviation, navigation, rail transportation, drilling platforms, offshore engineering, refining, and the petroleum industry, lubricating oil is subject to varying degrees of contamination during operation due to various factors. These contaminants include metallic and non-metallic particles caused by component wear, colloids, asphalt, sludge, mechanical fuel combustion products, and moisture in the air caused by the quality changes of lubricating oil during long-term operation. To effectively assess the status of mechanical wear, oil monitoring methods are often used to conduct in-depth research on the relationship between these contaminants, mechanical equipment, and the real-time status of lubricating oil.

[0003] Currently, oil monitoring technologies are generally divided into two types: offline monitoring and online testing. Offline monitoring often relies on laboratory analysis techniques with periodic sampling. However, in industries such as mining, wind power, thermal power, and hydropower generation, drilling platforms, offshore engineering, and large-scale construction machinery, oil consumption often exceeds 600 liters. Offline sampling, which only takes a few hundred milliliters, is not necessarily representative, diluting useful wear particles and failing to identify the underlying problem. These industries also face difficulties in sampling, making regular offline monitoring difficult and limiting their application. Furthermore, equipment on continuous production lines and equipment that cannot be easily shut down also faces the challenge of regular sampling. Furthermore, existing online monitoring equipment monitors lubricant properties online by installing a variable-diameter monitoring device. However, when the oil delivery pressure needs to be adjusted, the flow rate of the oil in the large-diameter oil pipeline changes as it passes through the monitoring device, altering the set uniform flow rate of the entire oil circulation circuit. This makes it difficult to comprehensively monitor the oil's properties online in real time. Summary of the Invention

[0004] The present application provides an online oil monitoring device for oil circuits with large diameters and a wide flow rate range, which monitors the quality of the oil in real time, thereby achieving real-time tracking of the operating status of mechanical equipment.

[0005] The present application provides an online oil monitoring device for a large-diameter and wide-flow-rate oil circuit, comprising: a structure having a T-shaped flow channel inside the structure;

[0006] A flow guide assembly; the flow guide assembly includes a flow guide baffle and a rotating valve plate mounted at the intersection of the T-shaped flow channel, the flow guide baffle blocking the T-shaped flow channel so that the bottom of the T-shaped flow channel forms a U-shaped flow guide channel for the oil to pass through;

[0007] Monitoring sensor; the monitoring sensor includes at least two sensors distributed in the U-shaped guide channel for monitoring the characteristics of the oil;

[0008] Actuator mechanism; the actuator mechanism drives the rotating valve plate to rotate between a first setting state and a second setting state; wherein,

[0009] When the actuator mechanism drives the rotary valve plate to rotate to the first set state, the plane of the rotary valve plate is perpendicular to the flow direction of the oil to form a maximum blocking surface, and the oil is diverted through the U-shaped diversion channel and monitored by at least two sensors;

[0010] When the actuator mechanism drives the rotary valve plate to rotate to the second set state, the rotary valve plate rotates by a set angle along the flow direction of the oil, and the oil is diverted through both sides of the rotary valve plate and the U-shaped guide channel and is monitored by at least two of the sensors;

[0011] The oil online monitoring device for large-diameter and wide-flow-rate oil circuits also includes an integrated gateway, which collects oil characteristic data monitored by at least two of the sensors and performs data processing, edge computing analysis, and remote data transmission.

[0012] In the present invention, for different ranges of oil flow rate working conditions, by rotating the valve plate to switch different positions, the oil is allowed to pass through the sensor under a stable output state to perform online monitoring of the oil characteristics, creating a favorable medium environment for the online oil monitoring work, thereby improving the adaptability of the online oil monitoring to different flow rate working conditions.

[0013] In a specific embodiment, the T-shaped flow channel has a through transverse flow channel, and flanges are mounted on both ends of the transverse flow channel on the structure, making assembly and disassembly more convenient.

[0014] In a specific embodiment, the rotating valve plate is rotated and positioned in the transverse flow channel, thereby changing the flow volume of the transverse flow channel and matching the flow rate of the oil by changing the cross-sectional area of ​​the transverse flow channel.

[0015] In a specific embodiment, the T-shaped flow channel has a vertical flow channel perpendicular to the transverse flow channel, and the guide baffle is fixedly installed in the middle of the vertical flow channel. The sensor can fully collect oil characteristic data through the guidance.

[0016] In a specific embodiment, the actuator mechanism includes: a coupling mounted on the top of the structure, a rotating shaft connected to the coupling through a bearing assembly, and a reversing actuator for driving the rotating shaft to rotate; wherein,

For low-flow oil, the oil flow rate around the sensor is increased to fully acquire characteristic data of the oil.

[0019] In one specific embodiment, when the reversing actuator drives the rotary valve plate to rotate to the second set state, the rotary valve plate rotates to a set angle to form different offset gaps with the guide baffle. For high-velocity oil, the oil flow rate around the sensor is reduced to fully capture oil characteristic data.

[0030] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs.

[0032] To facilitate understanding of the oil online monitoring device for large-diameter, wide-flow-rate oil circuits provided in the embodiments of the present application, its application scenarios are first explained. Oil monitoring technology is generally divided into two forms: offline monitoring and online detection. Offline monitoring often uses laboratory analysis techniques with regular sampling. For wind, thermal, and hydropower industries, drilling platforms, marine engineering, large-scale engineering machinery and equipment, etc., the oil consumption is generally over 600L. Only a few hundred milliliters of offline sampling are taken, and the sampling is not necessarily representative. Useful wear particles are diluted, and the real problem cannot be discovered. These industries also have the problem of inconvenient sampling, making it difficult to carry out regular offline monitoring, and the application area is subject to certain restrictions. In addition, for equipment on continuous production lines and equipment that cannot be easily shut down, there is also the problem of being unable to carry out regular sampling. At the same time, in existing online monitoring equipment, the characteristics of the lubricating oil are monitored online by installing a variable-diameter structure monitoring device. When the oil delivery pressure needs to be adjusted, the oil in the large-diameter oil circuit changes its flow rate when passing through the monitoring device, changing the set uniform flow rate of the entire circulating oil circuit, and at the same time, it is impossible to fully monitor the oil characteristics online in real time. In view of this, the present application provides an online oil monitoring device for oil circuits with large diameters and wide flow rate ranges, which monitors the quality of the oil in real time, thereby achieving real-time tracking of the operating status of mechanical equipment.

[0033] refer to Figure 1 The oil online monitoring device for a large-diameter and wide-flow-rate-range oil circuit provided in an embodiment of the present application includes a structure 2; the structure 2 has a T-shaped flow channel inside; the overall shape of the structure 2 can be a variety of shapes such as round, square, and T-shaped. In the embodiment of the present application, the structure 2 preferably adopts a T-shape, and the preparation process of the T-shaped structure 2 is simple, and a three-way pipe is used as the main structure of the structure 2.

[0034] Furthermore, the T-shaped flow channel has a through transverse flow channel, and flanges 1 are mounted on both ends of the transverse flow channel on the structure 2. The flanges 1 are connected to the oil circulation line, making assembly and disassembly more convenient.

[0035] At the same time, the bottom of the structure 2 is sealed by the mounting flange 9 so that the oil can only circulate through the inner cavity of the structure 2 at a constant flow rate to monitor the oil characteristics online.

[0036] Specific, combined Figure 2 As shown in FIG, the inner cavity of the structure 2 in the present application is provided with a flow guide assembly. The flow guide assembly includes a flow guide baffle 8 and a rotating valve plate 7 mounted at the intersection of the T-shaped flow channel. The flow guide baffle 8 blocks the T-shaped flow channel, forming a U-shaped flow guide channel at the bottom of the T-shaped flow channel for the oil to pass through. The rotating valve plate 7 rotates within the transverse flow channel. This adjusts the flow rate of the oil by changing the flow rate of the transverse flow channel.

[0037] The T-shaped flow channel has a vertical flow channel perpendicular to the horizontal flow channel, and a guide baffle 8 is fixedly installed in the middle of the vertical flow channel. The installation of the guide baffle allows the oil to be diverted after passing through the horizontal flow channel or completely enter the U-shaped flow channel. The guided oil fully contacts the sensor to collect oil characteristic data.

[0038] When the oil characteristics are monitored online, the monitoring sensors include at least two sensors distributed in the U-shaped flow channel for monitoring the characteristics of the oil; the two sensors include at least two or more of a magnetic plug sensor, an impedance spectrum sensor, a viscosity sensor, a dielectric constant sensor, a moisture sensor, a magnetic rod sensor, a flow sensor, a temperature sensor, a wear sensor, and an oil multi-parameter composite sensor, so that the oil online monitoring device for a large diameter and wide flow rate range oil circuit in this application has multiple online monitoring methods. In the embodiment of the present application, there are two exemplary monitoring sensors, namely a magnetic plug sensor 10 installed on the mounting flange 9 and an impedance spectrum sensor 11 installed on the side wall of the vertical flow channel. Of course, in other embodiments of the present application, a variety of sensors such as magnetic plug sensors, impedance spectrum sensors, viscosity sensors, dielectric constant sensors, moisture sensors, magnetic rod sensors, flow sensors, temperature sensors, wear sensors, and oil multi-parameter composite sensors can be combined into two, three, four, etc. Optional installation is performed according to different application scenarios. In an embodiment of the present application, by setting up two sensors, the oil characteristics in the oil can be collected, and the integrated gateway collects the oil characteristic data monitored by at least two sensors for processing and edge computing analysis, thereby realizing online monitoring and remote monitoring of the oil and operating equipment.

[0039] At the same time, in the embodiment of the present application, in order to keep the flow rate of the oil unchanged after online monitoring through the structure 2, so as to cope with online monitoring of the oil under different flow rate conditions, the flow rate of the transverse flow channel is changed by adjusting the angle of the rotating valve plate 7 in the present application.

[0040] Specifically, it also includes an actuator mechanism, which drives the rotating valve plate 7 to rotate to be located in a first set state and a second set state; wherein, when the actuator mechanism drives the rotating valve plate 7 to rotate and is located in the first set state, the plane of the rotating valve plate 7 is perpendicular to the flow direction of the oil to form a maximum blocking surface, and the oil is diverted through the U-shaped guide channel and monitored by at least two sensors; when the actuator mechanism drives the rotating valve plate 7 to rotate and is located in the second set state, the rotating valve plate 7 rotates a set angle along the flow direction of the oil, and the oil is diverted through both sides of the rotating valve plate 7 and the U-shaped guide channel and is monitored by at least two sensors.

[0041] The actuator mechanism comprises a coupling 3 mounted on top of a structure 2, a rotating shaft 6 connected to the coupling 3 via a bearing assembly 5, and a reversing actuator 4 for driving the rotating shaft 6 in rotation. The bearing assembly 5 can utilize a double-row tapered roller bearing. The rotating shaft 6 is connected to the top center of a rotating valve plate 7 via bolts 12. Reversing actuator 4 issues control instructions based on the operating flow rate of the oil online monitoring device and the technical parameters of the configured oil online monitoring sensor. This control instruction drives the rotating valve plate 7 to rotate, adjusting the angle of the rotating valve plate 7 and changing the flow rate of the oil flowing through the U-shaped flow channel near the sensor.

[0042] Combine Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 This is a schematic diagram of an online oil monitoring device for a large-diameter, wide-flow-rate-range oil circuit, provided by an embodiment of the present application, in its first operating state, with the rotating valve plate 7 in its first set state. As can be seen, the top of the rotating valve plate 7 aligns with the top of the inner wall of the structure 2. When the reversing actuator 4 drives the rotating valve plate 7 to rotate to the first set state, the rotating valve plate 7 and the guide baffle 8 coincide with each other and lie on the same blocking surface. This increases the oil flow rate around the sensor for low-flow oil, allowing for full acquisition of oil characteristic data.

[0043] refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 This is a schematic diagram of an oil online monitoring device for an oil circuit with a large diameter and a wide flow rate range provided by an embodiment of the present application, which is in the second working state. The second working state is that the rotating valve plate 7 is in the second set state. It should be understood that the range of the second set state of the rotating valve plate 7 for oils with different flow rates is relatively large, and the second state generally refers to the oil that can circulate through the transverse flow channel. When the reversing actuator 4 drives the rotating valve plate 7 to rotate to the second set state, the rotating valve plate 7 rotates to a set angle to form different offset gaps with the guide baffle 8. For high-flow-rate oil, the oil flow rate around the sensor is reduced to fully obtain the characteristic data of the oil. The set angle of rotation of the rotating valve plate 7 in the second state is between 0°-90°. Thereby achieving a wider adjustment range.

[0044] For example, when the oil online monitoring device detects that the oil working flow rate is mismatched after passing through the structure 2, the reversing actuator 4 is controlled to drive the operation, and the rotating valve plate 7 expands or shrinks the offset gap during the rotation process, adjusts the oil flow rate to be uniform, and at the same time changes the flow rate of the oil near the sensor. These are all commonly used technical methods in the existing control field and will not be elaborated here.

[0045] In the present invention, for different ranges of oil flow rate working conditions, by rotating the valve plate 7 to switch different positions, the oil is allowed to pass through the sensor under a stable output state to perform online monitoring of the oil characteristics, creating a favorable medium environment for the online oil monitoring work, thereby improving the adaptability of the online oil monitoring to different flow rate working conditions.
