[0001] This application relates to the field of online oil monitoring technology, and more specifically, to an oil flow monitoring device and method. Background Technology

[0002] Existing oil level monitoring equipment frequently encounters problems such as air bubbles or incomplete filling of the monitoring unit, leading to distorted monitoring data and low data validity and accuracy. This results in invalid monitoring data being generated during the monitoring process. Ensuring the validity and accuracy of data in online oil level monitoring technology is fundamental. Currently, there is no effective monitoring system to address the issue of distorted monitoring data. Summary of the Invention

[0003] The purpose of this application is to provide an oil flow monitoring device and method, which can improve the effectiveness and reliability of monitoring data.

[0004] In a first aspect, embodiments of this application provide an oil flow monitoring device, including an oil detection tank, a detection unit, a power pump, and a flow meter;

[0005] The first end of the detection oil tank is connected to the first end of the power pump, and the second end of the detection oil tank is connected to the first oil circuit of the device under test.

[0007] The second end of the power pump is connected to the second oil circuit of the device under test;

[0008] The flow meter is located between the second end of the detection oil tank and the first oil passage of the device under test.

[0009] In the above implementation process, the oil flow monitoring device monitors the actual flow rate at the second end of the detection oil tank through a flow meter, and calculates the theoretical flow rate at the first end of the detection oil tank through a power pump. By comparing the theoretical calculation with the actual measurement, the difference between the actual flow rate and the theoretical flow rate is used to determine whether there is an abnormality inside the detection oil tank. This achieves the purpose of monitoring, feedback, and adjustment of the oil tank, solving problems such as air bubbles and incomplete filling that often occur in oil monitoring, and ensuring the validity of the detection data obtained by the detection unit. Thus, the oil flow monitoring device can achieve the technical effect of improving the validity and reliability of monitoring data.

[0011] In the above implementation process, the processor can receive the actual flow information obtained by the flow meter and record, calculate and process it.

[0012] Furthermore, the processor is connected to the power pump.

[0013] In the above implementation process, the processor is connected to the power pump. On the one hand, the processor can receive the operating parameter data of the power pump and calculate the theoretical flow rate of the oil being tested through the power pump. On the other hand, the processor can feed back signals to the power pump and adjust the operating parameters of the power pump so that the theoretical flow rate of the power pump and the actual flow rate of the flow meter are consistent, thus avoiding problems such as air bubbles or incomplete filling in the oil sump.

[0014] Furthermore, the device also includes an alarm connected to the processor.

[0015] During the above implementation process, the processor can issue an alarm to ensure the normal operation of the oil monitoring system.

[0016] Furthermore, the device also includes a signal acquisition unit, which is connected to the power pump and the processor respectively.

[0017] In the above implementation process, the signal acquisition device can collect the operating parameter data of the power pump and feed it back to the processor, so that the processor can perform theoretical calculations based on the operating parameter data of the power pump to obtain the theoretical flow rate through the power pump.

[0018] Furthermore, the detection unit includes one or more of a moisture contamination detector, an abrasive contamination detector, and a viscosity detector.

[0019] In the above implementation process, the detection unit includes one or more of the following: moisture contamination detector, abrasive contamination detector, and viscosity detector; optionally, the detection unit may also include other oil parameter detection, which will not be listed here.

[0020] Furthermore, the device also includes a regulator disposed on the power pump.

[0021] In the above process, the regulator can adjust the operating parameters of the power pump to keep the theoretical flow rate of the power pump consistent with the actual flow rate of the flow meter.

[0022] Furthermore, the power pump is an electric pump.

[0023] In the above implementation process, the power pump is an oil pump driven by an electric motor; alternatively, the power pump can also be other types of oil pumps, which are not limited here.

[0024] Furthermore, the flow meter is a differential pressure flow meter.

[0025] In the above implementation process, differential pressure flow meters have the characteristics of simple structure, convenient maintenance, stable performance, and reliable use.

[0026] Furthermore, the device also includes a flow calculator, which is mounted on the power pump.

[0027] In the above implementation process, the flow calculator can directly calculate the flow rate using the operating parameters of the power pump, and then feed the calculated theoretical flow rate back to the data center, thus eliminating the need for a processor to calculate the theoretical flow rate.

[0047] This application provides an oil flow monitoring device and method, which can be applied to the field of online oil monitoring. The device monitors the actual flow rate at the second end of the oil tank using a flow meter, and calculates the theoretical flow rate at the first end of the oil tank using a power pump. By comparing the theoretical calculation with the actual measurement, the difference between the actual and theoretical flow rates is used to determine whether there are any abnormalities inside the oil tank. This allows for monitoring, feedback, and adjustment of the oil tank, solving problems such as air bubbles and incomplete filling that frequently occur in oil monitoring, and ensuring the validity of the detection data obtained by the detection unit. Therefore, this oil flow monitoring device can improve the effectiveness and reliability of monitoring data.

[0048] See Figure 1 , Figure 1 This application provides a schematic diagram of the structure of an oil flow monitoring device, which includes an oil detection tank 100, a detection unit 200, a power pump 300, and a flow meter 400.

[0049] For example, the first end 110 of the detection oil tank 100 is connected to the first end 310 of the power pump 300, and the second end 120 of the detection oil tank 100 is connected to the first oil passage 510 of the device under test.

[0050] For example, the power pump 300 draws test oil from the device under test, and the test oil tank 100 is filled with oil, thereby testing the oil in the test oil tank 100.

[0051] For example, the detection unit 200 is installed on the detection oil tank 100.

[0052] For example, the detection unit 200 is installed on the detection oil tank 100. Optionally, the sensor part of the detection unit 200 is installed inside the detection oil tank 100 to detect various data of the oil, such as water contamination, abrasive contamination, oil viscosity detection, etc. The detection unit 200 can grasp the state of the oil in the tested equipment and monitor whether the oil is normal, thereby ensuring the stable operation of the tested equipment.

[0053] In some embodiments, the detection unit 200 includes one or more of a moisture contamination detector, an abrasive contamination detector, and a viscosity detector; optionally, the detection unit 200 may also include other oil parameter detectors, which will not be listed here.

[0054] For example, the second end 320 of the power pump 300 is connected to the second oil passage 520 of the device under test.

[0055] For example, the power pump 300 draws test oil from the second oil passage 520 of the device under test and fills the test oil tank 100 with oil.

[0056] For example, the flow meter 400 is disposed between the second end 120 of the detection oil sump 100 and the first oil passage 510 of the device under test.

[0057] For example, the flow meter 400 is disposed between the second end 120 of the detection oil tank 100 and the first oil passage 510 of the device under test. During the process of the oil being tested flowing back to the device under test through the second end 120 of the detection oil tank 100, the flow meter 400 can count its flow rate to determine whether the internal condition of the detection oil tank 100 is normal.

[0058] In some implementation scenarios, the equipment under test can be large mechanical equipment, such as a hydroelectric generator set; optionally, the oil under test is the lubricating oil in the equipment under test.

[0059] In some embodiments, the oil flow monitoring device monitors the actual flow rate at the second end 120 of the detection oil sump 100 via a flow meter 400, and calculates the theoretical flow rate at the first end 110 of the detection oil sump 100 via a power pump 300. By comparing the theoretical calculation with the actual measurement, the difference between the actual and theoretical flow rates is used to determine whether there are any abnormalities inside the detection oil sump 100. This achieves the purpose of monitoring, providing feedback, and adjusting the oil sump, solving problems such as air bubbles and incomplete filling that often occur in oil monitoring, and ensuring the validity of the detection data obtained by the detection unit 200. Thus, the oil flow monitoring device can achieve the technical effect of improving the validity and reliability of monitoring data.

[0060] See Figure 2 , Figure 2 This is a schematic diagram of another oil flow monitoring device provided in an embodiment of the present application. The oil flow monitoring device includes an oil detection tank 100, a detection unit 200, a power pump 300, a flow meter 400, and a processor 600.

[0061] It should be understood that the detection oil tank 100, detection unit 200, power pump 300, and flow meter 400 have been described above, and will not be repeated here to avoid repetition.

[0062] For example, the oil monitoring device also includes a processor 600, which is connected to the flow meter 400.

[0063] Optionally, the processor 600 can receive the actual flow information obtained by the flow meter 400 and record, calculate and process it.

[0064] In some implementations, the processor 600 may be a computer or other final execution unit for information processing or program execution.

[0065] For example, the processor 600 is connected to the power pump 300.

[0066] For example, the processor 600 is connected to the power pump 300. On the one hand, the processor can receive the operating parameter data of the power pump 300 and calculate the theoretical flow rate of the oil being tested through the power pump 300. On the other hand, the processor 600 compares the theoretical flow rate of the power pump 300 with the actual flow rate of the flow meter 400 to determine whether the oil in the detection oil sump 100 is abnormal. If there is an abnormality, the processor 600 can feed back a signal to the power pump 300 and adjust the operating parameters of the power pump 300 so that the theoretical flow rate of the power pump 300 and the actual flow rate of the flow meter 400 are consistent, thus avoiding problems such as air bubbles or incomplete filling in the detection oil sump 100.

[0067] For example, the oil flow monitoring device also includes an alarm connected to the processor 600.

[0068] For example, during the actual operation of the oil flow monitoring device, the alarm can compare the actual flow rate of the flow meter 400 with the theoretical calculated flow rate of the power pump 300 to determine the flow rate in the detection oil tank 100 during the monitoring process. If an internal abnormality is detected in the detection oil tank 100, the processor 600 can sound an alarm through the alarm to ensure the normal operation of the oil monitoring.

[0069] In some embodiments, the oil flow monitoring device also includes a signal acquisition unit, which is connected to the power pump 300 and the processor 600 respectively.

[0070] For example, the signal acquisition device can collect the operating parameter data of the power pump 300 and feed it back to the processor 600, so that the processor 600 can perform theoretical calculations based on the operating parameter data of the power pump 300 to obtain the theoretical flow rate through the power pump 300.

[0071] In some embodiments, the oil flow monitoring device also includes a regulator mounted on the power pump 300.

[0072] For example, the regulator can adjust the operating parameters of the power pump 300 so that the theoretical flow rate of the power pump 300 is consistent with the actual flow rate of the flow meter 400, thereby ensuring that the oil sump 100 is normal and avoiding problems such as air bubbles or incomplete filling.

[0073] In some implementations, the power pump 300 is an electric pump.

[0074] For example, the power pump 300 is an electric motor-driven oil pump; alternatively, the power pump 300 may also be other types of oil pumps, which are not limited here.

[0075] For example, flow meter 400 is a differential pressure flow meter.

[0076] For example, a differential pressure flow meter, also known as a differential pressure orifice plate flow meter, is a high-range differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or a differential pressure transmitter, temperature transmitter, and pressure transmitter). It can measure the flow rate of gases, steam, liquids, and natural gas, and is widely used in process control and measurement in petroleum, chemical, metallurgical, power, heating, and water supply industries. It consists of a primary sensing element (throttling element) and a secondary device (differential pressure transmitter and flow display instrument), and is widely used for measuring the flow rate of gases, steam, and liquids. Differential pressure flow meters are characterized by simple structure, convenient maintenance, stable performance, and reliable operation.

[0077] In some embodiments, the oil flow monitoring device also includes a flow calculator, which is mounted on the power pump 300.

[0078] For example, the flow calculator can directly calculate the flow rate using the operating parameters of the power pump 300, and then feed the calculated theoretical flow rate back to the data center, thus eliminating the need to calculate the theoretical flow rate through the processor 600.

[0079] See Figure 3 , Figure 3 This is a flowchart illustrating an oil flow monitoring method provided in an embodiment of this application. The oil flow monitoring method is applied to... Figures 1 to 2 The oil flow monitoring device shown includes the following steps:

[0080] Step S100: Calculate the first flow rate value based on the operating parameters of the power pump 300;

[0081] Step S200: Receive the second flow rate value detected by the flow meter 400;

[0082] Step S300: Determine whether the error between the first flow rate value and the second flow rate value is within a preset range;

[0083] Step S400: If not, adjust the operating parameters of the power pump 300;

[0084] Step S500: If yes, receive the oil status data detected by the detection unit 200.

[0085] For example, after the step of adjusting the operating parameters of the power pump, the method further includes:

[0086] Calculate the first flow rate value based on the operating parameters of the power pump.

[0087] For example, the first flow rate value is the theoretical flow rate obtained by theoretical calculation based on the operating parameters of the power pump 300; the second flow rate value is the actual flow rate obtained by the flow meter 400.

[0088] In some implementations, after step S400, that is, after adjusting the operating parameters of the power pump 300, the process can return to step S100 to compare the first flow rate value and the second flow rate value.

[0089] In some implementation scenarios, the validity of monitoring data is fundamental to online oil monitoring technology. Existing monitoring devices often generate invalid data during the monitoring process, making it difficult to control and guarantee data validity, and lacking relevant monitoring mechanisms. This application provides an oil monitoring device that improves the validity of detection data during the monitoring process through flow monitoring.

[0090] For example, by adding a flow meter 400, the flow rate during the monitoring process is calculated and judged, that is, by determining the relationship between the actual flow rate and the theoretically calculated flow rate during the actual operation of the monitoring device, the flow rate in the detection oil tank 100 during the monitoring process is determined, thereby determining the state of the oil during the detection and thus determining the validity of the monitoring data.

[0091] In some implementations, the process of this oil flow monitoring device is illustrated below:

[0092] The power pump 300 draws a certain amount of oil, which enters the oil pipeline and is detected in the oil sump 100. At this time, the oil flow rate in the oil pipeline can be theoretically calculated and recorded as the first flow rate value. This value is stored in the processor 600 as the theoretically calculated value.

[0093] After the oil passes through the oil tank 100, the flow rate of the oil flowing into the oil pipe is measured by the flow meter 400, which is the second flow value. The flow meter is connected to the PC, and the actual flow value is recorded and stored in the PC in real time.

[0094] The oil in the oil tank 100 needs to be tested under full conditions. If the oil flow rate in the oil tank is abnormal, such as air bubbles or not being full, it will cause the data detected by the detection unit 200 to be distorted.

[0095] By comparing the theoretical oil flow rate before entering the detection oil tank 100—the first flow rate value—with the oil flow rate after exiting the detection oil tank 100—the second flow rate value, the oil flow rate status in the detection oil tank 100 can be determined.

[0096] If the flow rate is abnormal, the processor 600 will feed back to the power pump 300 to adjust the output of the power pump 300 so that it matches the flow rate required by the detection oil tank 100, thereby ensuring the validity of the data from the detection unit 200.

[0097] For example, compared with other oil monitoring devices, the oil flow monitoring device and method provided in this application monitor, provide feedback and adjust the theoretical and actual values ​​of the flow rate of the online oil monitoring device, so that the detection unit 200 can be in the optimal detection state, thereby ensuring the validity of the detection data; thus, the oil flow monitoring device can solve the problems of air bubbles and incomplete filling that often occur in oil monitoring, and can achieve the technical effect of improving the validity and reliability of monitoring data.
