Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of lubricating oil detection, and in particular to a detection pool. Background Art

[0002] Lubricating oil is typically built into mechanical equipment and at least partially soaks its internal components, lubricating them to reduce wear and tear caused by friction during operation and thus extend the service life of the equipment. However, as lubricating oil ages, its quality deteriorates, and this degraded lubricating oil's lubricating effect on the internal components of the equipment decreases, increasing wear and tear. Therefore, it's necessary to periodically test the lubricating oil in mechanical equipment and replace it promptly if its quality is substandard.

[0003] During the development of this invention, the inventors discovered that when components within mechanical equipment operate, frictional elements can create bubbles in the lubricating oil, which can affect detection accuracy. Currently, chemical defoaming is commonly used, eliminating bubbles by injecting a chemical defoamer into the lubricating oil. However, this method can cause the chemical defoamer to enter the lubricating oil, affecting its lubrication performance. This is particularly true when the lubricating oil is reinjected into the mechanical equipment, where the impact is even greater. Utility Model Content

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0022] See also Figure 1-3 The detection tank 1 includes a shell, which is used for the lubricating oil to be tested to flow through. The lubricating oil to be tested can be extracted from mechanical equipment, such as a gearbox or hydraulic equipment, and returns to the mechanical equipment after passing through the detection tank 1. The sensor 2 is installed in the shell. The sensor is used to detect the lubricating oil to be tested, so as to determine the quality parameters of the lubricating oil to be tested in the mechanical equipment.

[0023] For the above housings, see Figure 1-3The shell includes a bottom wall 11, a side wall 12 and a top wall 13. One end of the side wall 12 is connected to the bottom wall 11, and the other end of the side wall 12 is connected to the top wall 13. The bottom wall 11, the side wall 12 and the top wall 13 enclose a first inner cavity 14 for containing the lubricating oil to be tested. The top wall 13 is provided with a connecting hole 131, which connects the first inner cavity 14 with the external space. The connecting hole 131 is used for the sensor 2 to be inserted into the first inner cavity 14. The sensor 2 is used to detect the quality parameters of the lubricating oil to be tested. By setting the connecting hole 131 on the top wall 12, when installing the sensor 2, the sensor 2 can be inserted into the first inner cavity 14 from top to bottom. In some embodiments, the quality parameters include density, viscosity, water activity, dielectric constant, etc., and those skilled in the art can select the sensor 2 according to actual needs. An oil inlet hole 121 and an oil outlet hole 122 are provided on the side wall 12. Both the oil inlet hole 121 and the oil outlet hole 122 connect the first inner cavity 14 and the external space, and the oil inlet hole 121 and the oil outlet hole 122 are arranged opposite to each other. The lubricating oil to be tested flows into the first inner cavity 14 from the oil inlet hole 121 and then flows out from the oil outlet hole 122. Along the direction perpendicular to the bottom wall 11, the first distance between the oil inlet hole 121 and the top wall 13 is greater than the second distance between the oil outlet hole 122 and the bottom wall 11, so that the oil outlet hole 122 is located above the oil inlet hole 121. When the lubricating oil to be tested flows from the oil inlet hole 121 into the first inner cavity 14 and then flows out from the oil outlet hole 122, the lubricating oil to be tested flows upward, and the upward flow of the lubricating oil to be tested will cause the bubbles in the lubricating oil to be tested to float upward. The sensor 2 for detecting the quality of the lubricating oil to be tested can be inserted into the first inner cavity 14 from the connecting hole 131, and the probe 21 of the sensor 2 is located at the oil inlet hole 121. 1 and the oil outlet 122, which helps the probe 21 avoid most of the floating bubbles, thereby reducing the impact of bubbles on the detection results of the sensor 2. In addition, by allowing the lubricant to be tested to flow upward, the time the lubricant to be tested stays in the detection tank 1 can be increased, which is conducive to the bubbles in the lubricant to be tested floating up, and the bubbles that float up can be discharged through the oil outlet 122 under the load of the lubricant to be tested at a certain flow rate. At this time, the bubbles contained in the lubricant to be tested in the detection tank 1 are greatly reduced. Then, the lubricant to be tested in the detection tank 1 is tested by the sensor 2, which can greatly reduce the measurement error caused by bubbles. In addition, the oil inlet 121 and the oil outlet 122 are staggered in the direction perpendicular to the direction from the bottom wall 11 to the top wall 13. On the one hand, this can extend the flow path of the lubricant to be tested in the detection tank 1, so that the lubricant to be tested with a certain flow rate spends more time in the first inner cavity 14, so as to facilitate the floating of bubbles and reduce the impact of bubbles on the measurement results. On the other hand, more lubricating oil to be tested can be made to flow in the detection tank 1, so that the sensor 2 can detect the flowing lubricating oil, so that the sensor 2 can measure continuous and accurate data, thereby improving the accuracy of the measurement.

[0024] It should be noted that the first distance refers to the distance between the axial center axis of the oil outlet 122 and the bottom wall 11, and the second distance refers to the spacing between the axial center axis of the oil inlet 121 and the bottom wall 11. The surface of the bottom wall 11 facing away from the top wall is the placement surface. This placement surface is perpendicular to the direction from the bottom wall 11 to the top wall 13 and is a flat surface. When the placement surface of the test cell 1 is placed on a horizontal support surface, the direction from the bottom wall 11 to the top wall 13 is vertical, thereby positioning the oil outlet 122 above the oil inlet 121, allowing bubbles to float up and flow out of the oil outlet 122. Optionally, the sidewalls 12 are arranged parallel to the direction from the bottom wall 11 to the top wall 13, so that when the test cell 1 is placed on a support surface, the sidewalls 12 are arranged vertically, so that the oil outlet 122 and the oil inlet 121 are spaced apart in the vertical direction. This increases the vertical flow path of the lubricating oil to be tested within the test cell 1 and improves the time the lubricating oil to be tested remains within the test cell 1.

[0025] In some embodiments, the cross-sectional shape of the sidewall 12 can be circular, rectangular, or the like.

[0026] In some embodiments, along the direction from the bottom wall 11 to the top wall 13, the inner wall surface of the oil inlet hole 121 close to the bottom wall 11 is higher than the inner wall surface of the oil inlet hole 121 close to the top wall 13, so that the lowest point of the oil outlet hole 122 is higher than the highest point of the oil inlet hole 121, thereby increasing the height difference between the oil outlet hole 122 and the oil inlet hole 121, thereby increasing the vertical flow path of the lubricating oil to be tested, which is beneficial to increasing the number of floating bubbles and making the measurement results more accurate.

[0027] In some embodiments, along the direction from bottom wall 11 to top wall 13, the inner wall surface of oil inlet hole 121, which is close to bottom wall 11, is separated from bottom wall 11 by a first predetermined distance. This prevents a drill or milling tool from cutting the bottom wall during machining, thereby reducing the difficulty of machining oil inlet hole 121. Along the direction from bottom wall 11 to top wall 13, the inner wall surface of oil outlet hole 122, which is close to top wall 13, is separated from top wall 13 by a second predetermined distance, thereby reducing the difficulty of machining oil outlet hole 122.

[0028] In other embodiments, the oil outlet hole 122 is located at one end of the side wall 12 near the top wall 13 and extends to the top wall 13. The oil inlet hole 121 is located at the other end of the side wall 12 near the bottom wall 11 and extends to the bottom wall 11. This maximizes the vertical spacing between the oil inlet hole 121 and the oil outlet hole 122, extending the vertical flow path of the lubricating oil to be tested. The rising bubbles gather on the top wall 13 and are then discharged from the oil outlet hole 122. Furthermore, the lubricating oil to be tested between the oil inlet hole 121 and the oil outlet hole 122 is caused to flow, preventing the generation of stagnant oil and enabling the sensor 2 to measure continuous and accurate data.

[0029] In an embodiment of the present invention, the detection pool 1 includes a shell, which includes a bottom wall 11, a side wall 12 and a top wall 13. The bottom wall 11, the side wall 12 and the top wall 13 enclose a first inner cavity 14 for containing the lubricating oil to be tested. The side wall 12 is provided with an oil inlet hole 121 and an oil outlet hole 122. The first distance between the oil outlet hole 122 and the bottom wall 11 is greater than the second distance between the oil inlet hole 121 and the bottom wall 11, so that the oil outlet hole 122 is located above the oil inlet hole 121. When the lubricating oil to be tested flows into the first inner cavity 14 from the oil inlet hole 121, the lubricating oil to be tested flows upward and flows out of the first inner cavity 14 from the oil outlet hole 122. During the upward flow of the lubricating oil to be tested, the bubbles in the lubricating oil to be tested will be driven to float upward, and the sensor for detecting the quality of the lubricating oil to be tested will be used to detect the quality of the lubricating oil to be tested. The sensor 2 can be inserted into the first inner cavity 14 from the connecting hole 131. The probe of the sensor 2 is located between the oil inlet hole 121 and the oil outlet hole 122, which is beneficial for the probe 21 to avoid most of the floating bubbles, thereby reducing the influence of the bubbles on the detection results of the sensor 2; in addition, the oil outlet hole 121 and the oil inlet hole 122 are staggered to increase the flow path of the lubricating oil to be tested in the first inner cavity 14, so that the time the lubricating oil to be tested is in the first inner cavity 14 is increased, and the floating bubbles increase accordingly, further reducing the influence of bubbles on the detection of the sensor 2.

[0030] The present invention also provides an embodiment of the lubricating oil detection device, see Figure 3 The lubricating oil detection device includes a sensor 2 and the above-mentioned detection pool 1. The sensor 2 is installed in the shell of the detection pool 1. The sensor 2 is used to detect the quality parameters of the lubricating oil to be tested in the detection pool 1. For the structure of the detection pool 1, please refer to the above-mentioned embodiment, which will not be described here one by one.

[0031] It should be noted that sensor 2 includes a probe 21, which is inserted into the first inner cavity 14 of the housing through the connection hole 131. When the probe 212 of sensor 2 is inserted into the first inner cavity 14, it is positioned perpendicularly from the bottom wall 11 to the top wall 13, between the oil inlet 121 and the oil outlet 122. Probe 21 is positioned closer to one side of the oil outlet 122, helping it avoid rising bubbles and reducing interference. Probe 21 is positioned between the oil inlet 121 and the oil outlet 122, ensuring that it detects the flowing lubricant being tested.
