Description

Technical Field

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

[0002] In related technologies, when it is necessary to monitor the oil in the oil circuit, it is usually necessary to take samples periodically and send them to the laboratory for analysis, which cannot achieve real-time monitoring to obtain the real-time operating results of the equipment. Utility Model Content

[0003] The purpose of this disclosure is to provide an oil monitoring device that can monitor the oil circuit in real time.

[0004] To achieve the above objectives, this disclosure provides an oil monitoring device, which includes a bypass and a monitoring component. The bypass is connected to an oil tank and is configured in parallel with the main oil circuit on the oil tank. The bypass includes an oil outlet line and an oil return line, each having a first end and a second end arranged opposite to each other. The first end is used to communicate with the oil tank. The monitoring component is connected between the two second ends and is used to collect parameters of the oil flowing through it. The parameters of the oil include at least one of viscosity, abrasive particles, and micro-water content.

[0005] Optionally, in the height direction of the oil tank, the first end of the oil outlet pipeline is configured to be higher than the first end of the oil return pipeline.

[0006] Optionally, the monitoring component includes an electrical box and an abrasive monitoring module. The abrasive monitoring module is electrically connected to the electrical box and communicates between the two second ends. The abrasive monitoring module is integrated into the housing of the electrical box.

[0007] Optionally, the electrical box has a first box and a second box, wherein the abrasive monitoring module is disposed in the second box, and the first box and the second box are separated from each other.

[0008] Optionally, the oil monitoring device includes a viscosity monitoring module, which is located upstream of the abrasive monitoring module.

[0009] Optionally, the oil monitoring device includes a micro-water monitoring module, which is located downstream of the abrasive monitoring module.

[0010] Optionally, the viscosity monitoring module includes a first adapter connected upstream of the abrasive monitoring module and detachably connected to a second housing, and / or the micro-moisture monitoring module includes a second adapter connected downstream of the abrasive monitoring module and detachably connected to a second housing.

[0014] The above technical solution, by setting up a bypass in parallel with the main oil circuit, allows a portion of the oil in the tank to flow to the bypass during normal system operation. This bypass then flows through a monitoring component connected to the outlet and return oil lines, enabling the monitoring component to acquire at least one parameter of the oil's viscosity, abrasive particles, and micro-water content. The oil can then flow back to the tank through the return oil line. Therefore, during normal system operation, oil can be drawn in real-time through the bypass, meaning the oil flows through the bypass and the monitoring component in real-time. The monitoring component can acquire the oil's instantaneous status parameters, achieving real-time oil monitoring. The structure is simple, installation is convenient, and by setting up the bypass, the operation of the main oil circuit is avoided when monitoring the oil's status.

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the scope of this disclosure.

[0020] According to a specific embodiment of this disclosure, refer to Figures 1 to 5 As shown, an oil monitoring device is provided. The oil monitoring device includes a bypass 1 and a monitoring component 2. The bypass 1 is used to connect to the oil tank 10 and is set in parallel with the main oil circuit 20 on the oil tank 10. The bypass 1 includes an oil outlet pipe 11 and an oil return pipe 12. The oil outlet pipe 11 and the oil return pipe 12 each have a first end and a second end arranged opposite to each other. The first end is used to communicate with the oil tank 10. The monitoring component 2 is connected between the two second ends and is used to collect the parameters of the oil flowing through it. The parameters of the oil include at least one of viscosity, abrasive particles, and micro-water content.

[0021] Through the above technical solution, by setting a bypass 1 in parallel with the main oil circuit 20, the oil in the oil tank 10 can partially flow to the bypass 1 during normal system operation. This allows the oil to flow through the monitoring component 2 connected between the oil outlet line 11 and the oil return line 12, enabling the monitoring component 2 to acquire at least one of the parameters of the oil's viscosity, abrasive particles, and micro-water content. The oil can then flow back to the oil tank 10 through the oil return line 12. Therefore, during normal system operation, oil can be extracted in real time through the bypass 1, meaning the oil can flow through the bypass 1 and the monitoring component 2 on it in real time. The monitoring component 2 can acquire the oil's instantaneous status parameters, achieving real-time monitoring of the oil. This method is simple in structure, easy to install, and by setting the bypass 1, the operation of the main oil circuit 20 is avoided when monitoring the oil's status.

[0022] Viscosity refers to the internal friction generated during flow, reflecting the oil's viscosity. Abrasive particles are various solid particles present in the oil, including metal abrasive particles, dust, sand, and other impurities. Trace water content is the amount of trace water contained in the oil.

[0023] In addition, multiple oil parameter monitoring modules can be set as needed, such as moisture monitoring, contamination monitoring, dielectric constant monitoring, etc. This disclosure does not impose specific limitations on this.

[0024] In some embodiments of this disclosure, the first end of the oil outlet pipe 11 is positioned higher than the first end of the oil return pipe 12 in the height direction of the oil tank 10. This allows the monitoring component 2 to handle low oil flow rate requirements, enabling the oil to flow towards the oil outlet pipe 11 under gravity, thus achieving real-time oil extraction. Furthermore, after the extracted oil passes through the monitoring component 2 and its parameters are collected, it can flow back into the oil tank 10 under gravity. Therefore, there is no need to install a power drive device in the bypass 1 to extract the oil, saving energy. The oil monitoring device is also small in size and lightweight, reducing its footprint and improving the ease of installation and maintenance to meet various installation scenarios.

[0025] In some embodiments of this disclosure, reference is made to Figure 5 As shown, the monitoring component 2 includes an electrical box 21 and an abrasive particle monitoring module 22. The abrasive particle monitoring module 22 is electrically connected to the electrical box 21 and connects between two second terminals. The abrasive particle monitoring module 22 is integrated into the housing of the electrical box 21. In this way, the data collected by the monitoring component 2 can be transmitted to the electrical box 21 for calculation and analysis. At the same time, the electrical box 21 can provide physical protection for the abrasive particle monitoring module 22, preventing dust, moisture, etc. from entering and affecting the monitoring results. Furthermore, the abrasive particle monitoring module 22 can be integrated into the motor housing to reduce space occupation and improve the assembly efficiency of the monitoring component 2.

[0026] In some embodiments of this disclosure, reference is made to Figures 2 to 4 As shown, the electrical box 21 has a first box 211 and a second box 212. The abrasive particle monitoring module 22 is disposed in the second box 212. The first box 211 and the second box 212 are separated from each other. In this way, the electrical components performing calculations and analysis in the electrical box 21 can be separated from the abrasive particle monitoring module 22. This achieves the modular design of the electrical box 21, while also preventing the oil flowing through the abrasive particle monitoring module 22 from entering the first box 211 and affecting the calculation of the electrical components. Furthermore, it prevents the electrical components in the monitoring module from generating electromagnetic interference to the abrasive particle monitoring module 22, which would affect the reliability of the parameters.

[0027] In some embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, the oil monitoring device includes a viscosity monitoring module 23, which is located upstream of the abrasive monitoring module 22. This allows for the simultaneous acquisition of both the oil's viscosity and abrasive parameters, enabling comprehensive oil monitoring and improving the overall comprehensiveness and accuracy of oil condition assessment.

[0028] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 3 As shown, the oil monitoring device includes a micro-water monitoring module 24, which is located downstream of the abrasive monitoring module 22. This allows for the simultaneous acquisition of oil viscosity, abrasive parameters, and micro-water parameters, enabling comprehensive oil monitoring and improving the comprehensiveness and accuracy of oil condition assessment.

[0029] In some embodiments of this disclosure, reference is made to Figure 2 and Figure 3As shown, the viscosity monitoring module 23 includes a first adapter 231, which is connected upstream of the abrasive monitoring module 22 and detachably connected to the second housing 212. Alternatively, the moisture monitoring module 24 includes a second adapter 241, which is connected downstream of the abrasive monitoring module 22 and detachably connected to the second housing 212. This allows the viscosity monitoring module 23 to be connected to the electrical housing 21 via the first adapter 231, and / or the moisture monitoring module 24 to be connected to the electrical housing 21 via the second adapter 241. This improves the ease of assembly of the monitoring components 2. Simultaneously, the oil can enter the viscosity monitoring module 23 through the first adapter 231. Since the first adapter 231 is connected upstream of the abrasive monitoring module 22, after viscosity monitoring, the oil flows through the abrasive monitoring module 22 for abrasive monitoring, and then enters the second adapter 241 for micro-moisture monitoring, ensuring a smooth flow path of the oil between the viscosity monitoring module 23, the abrasive monitoring module 22, and the micro-moisture monitoring module 24. Both the first adapter 231 and the second adapter 241 are detachably connected to the second housing 212, improving the assembly efficiency of the oil monitoring device and facilitating its maintenance and replacement.

[0030] The first adapter 231 and the second adapter 241 can be connected to both ends of the abrasive monitoring module 22, respectively, and this disclosure does not impose specific limitations on this. Both the first adapter 231 and the second adapter 241 can be connected to the second housing 212 by fasteners. Similarly, the viscosity monitoring sensor 232 and the first adapter 231, and the micro-moisture monitoring sensor 242 and the second adapter 241 can be connected by fasteners. The fasteners can be bolts or other workpieces used for connection, and this disclosure does not impose specific limitations on this.

[0031] In other embodiments of this disclosure, the viscosity monitoring module 23 and the micro-moisture monitoring module 24 can both be connected to one of the first adapter 231 and the second adapter 241, and connected to the electrical box 21 through either the first adapter 231 or the second adapter 241, and this disclosure does not impose any specific limitations. Alternatively, the micro-moisture monitoring module 24 can be located upstream of the abrasive particle monitoring module 22, and the viscosity monitoring module 23 can be located downstream of the abrasive particle monitoring module 22, and this disclosure does not impose any specific limitations.

[0032] In some embodiments of this disclosure, reference is made to Figure 3As shown, a first sealing ring 3 is provided between the first adapter 231 and the second housing 212, and a second sealing ring 4 is provided between the second adapter 241 and the second housing 212. Thus, the second sealing ring 4 provides a seal between the first adapter 231 and the second housing 212, and also provides a seal between the second adapter 241 and the second housing 212, thereby ensuring the sealing of the connection between the first adapter 231 and the second adapter 241 and the second housing 212, and preventing oil leakage during the flow between the first adapter 231, the second housing 212, and the second adapter 241.

[0033] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the viscosity monitoring module 23 includes a viscosity monitoring sensor 232, which is inserted into the first adapter 231. A third sealing ring 5 is provided between the viscosity monitoring sensor 232 and the first adapter 231. In this way, the viscosity monitoring module 23 collects the viscosity parameters of the oil through the viscosity monitoring sensor 232 and transmits them to the electrical box 21. The third sealing ring 5 improves the seal between the viscosity monitoring sensor 232 and the first adapter 231, ensuring the airtightness of the connection between the viscosity monitoring sensor 232 and the first adapter 231 and preventing oil entering the first adapter 231 from leaking through the connection between the viscosity monitoring sensor 232 and the first adapter 231.

[0034] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the micro-moisture monitoring module 24 includes a micro-moisture monitoring sensor 242, which is inserted into the second adapter 241. A fourth sealing ring 6 is provided between the micro-moisture monitoring sensor 242 and the second adapter 241. In this way, the micro-moisture monitoring module 24 collects the micro-moisture parameters of the oil through the micro-moisture monitoring sensor 242 and transmits them to the electrical box 21. The fourth sealing ring 6 improves the seal between the micro-moisture monitoring sensor 242 and the second adapter 241, ensuring the airtightness of the connection between them and preventing oil entering the second adapter 241 from leaking through the connection point.
