Description

Technical Field

[0001] This invention relates to a visual turbidity measuring device for identifying particle disturbances caused by soft particles and moisture contamination when measuring particle contamination levels in lubricating oils and hydraulic oils. More specifically, it relates to a visual turbidity measuring device for identifying particle disturbances caused by soft particles and moisture contamination when measuring particle contamination levels in lubricating oils and hydraulic oils, enabling comparative analysis between visual confirmation and diagnosis based on turbidity charts and electronic contamination measurements based on laser optical sensors. Background Technology

[0002] The content described in this section is only for providing background information on one embodiment of the present invention and does not constitute prior art.

[0003] The lubricating oils used in power generation equipment and instruments vary depending on the operating conditions, but their lubrication performance inevitably deteriorates due to heating or the introduction of foreign matter. Therefore, regular sampling and analysis are necessary. In particular, if the lubrication equipment is operating under abnormal conditions, monitoring the generation tendency of metal wear particles under abnormal conditions through contamination levels can greatly help stabilize the operation of the lubrication equipment and prevent accidents in advance.

[0004] Furthermore, considering the saturation humidity within the lubricating oil, if a malfunction is caused by a leak in the lubricating oil cooler, the influx of water will cause a rapid increase in the free water content of the lubricating oil in a short period. This emulsification will lead to changes in viscosity, preventing the formation of a suitable oil film required by the instrument, resulting in instrument damage and, in severe cases, serious malfunctions of mechanical devices. In addition, lubrication management includes monitoring the viscosity and contamination level of the lubricating oil. Continuous monitoring of these parameters can ensure more stable equipment operation, minimize economic losses due to excessive operating costs, and improve the operating efficiency of machinery / equipment.

[0005] As mentioned above, for the stable operation of machinery / equipment, the management of lubricating oil and hydraulic oil is an essential management item. The evaluation of lubricating oil and hydraulic oil requires on-site sampling, which involves a series of steps including air transport of the sampled lubricating oil and hydraulic oil, the time and cost of analysis by the analytical agency, and feedback from the A / S center. This presents a problem of significant costs and time consumption. Furthermore, current sampling operations rely heavily on manual sampling by professional personnel, making them highly dependent on human error and potentially leading to problems. Managing the oil contamination status and operation of individual excavators is also a time-consuming and labor-intensive task. Existing technical literature includes Korean Patent Publication No. 10-0789724.

[0006] The background technology mentioned refers to technical information that the inventor possesses in order to derive this invention or that is learned during the process of deriving this invention, and does not necessarily have to be prior art disclosed to the general public before applying for this invention.

[0035] The measuring device body 110 is structured to form a space for the measuring section outer cover 111, which houses the sample cover for taking samples as samples for measuring particle contamination levels in lubricating oil and hydraulic oil. For example, respectively in... Figures 3 to 7 As shown, the main body 110 of this measuring device also includes a front surface door 112, which opens and closes on the front surface of the space of the measuring section cover 111, which houses a sample cover for measuring the particle contamination level in lubricating oil and hydraulic oil. The sample cover is a sample container filled with lubricating oil or hydraulic oil, used for measuring the particle contamination level in lubricating oil and hydraulic oil, and may be made of a transparent bottle.

[0036] Furthermore, as in respectively Figures 3 to 7 As shown, the measuring device body 110 forms an outer casing structure, which is provided with a front surface door 112 that can be opened and closed on the front surface of the space of the measuring unit outer casing 111, where a sample outer casing for measuring particle contamination levels in lubricating oil and hydraulic oil is placed. The space of the measuring unit outer casing 111 can be opened and closed by opening and closing the front surface door 112, and a portion of the front surface of the front surface door 112 can be made of a transparent material. That is, even when the front surface door 112 is closed, the interior of the space of the measuring unit outer casing 111 can be clearly observed with the naked eye. For example, Figure 3 The camera 151 of the imaging management unit 150 (described later) can be installed at the lower end of the front surface door 112, but it is not limited to this and can also be located inside the measuring device body 110, i.e., on the side of the sample. Furthermore, a portion of the side of the space forming the measuring unit cover 111 of the measuring device body 110 can be made of a transparent material that allows the interior to be seen.

[0037] The turbidity chart 120 is designed so that the degree of contamination can be visually confirmed and diagnosed from the rear surface of the sample cover, which is located within the space of the measuring section cover 111 of the measuring device body 110. This turbidity chart 120 is an ASTM Bar Chart (International Standard ASTM D4176) that allows for visual confirmation and diagnosis of the presence of moisture, thermal deposits, and particulate contaminants in lubricating oil or hydraulic oil. Specifically, the turbidity chart 120 performs the function of visually confirming and diagnosing the contamination level of lubricating oil or hydraulic oil. That is, as a background plate for confirming the turbidity of the oil, it enables visual management of lubrication.

[0038] The laser optical sensor 130 is a structure used to measure the contamination level of a sample cover disposed within the space of the measuring section cover 111 of the measuring device body 110. This laser optical sensor 130 can be used in conjunction with the visual management of the turbidity chart 120 for electronic contamination measurement. The laser optical sensor 130 can be positioned at a location where the contamination level of the sample cover disposed within the space of the measuring section cover 111 of the measuring device body 110 can be measured using laser technology.

[0039] The display 140 is structured to show the results of the contamination measurement of the sample cover as measured by the laser optical sensor 130. For example... Figure 3 The display 140 is located on the upper left side of the front surface of the measuring device body 110, allowing the administrator to confirm the measurement results. The display 140 can display the color values ​​of the measurement results numerically under the control of the control unit 160. Furthermore, the display 140 can be configured as a touchpad that allows user operation.

[0040] The image management unit 150 stores and manages images of the sample casing located in the space of the measuring device body 110. For example... Figure 2 The image management unit 150 may include: a camera 151 for capturing images of the sample cover disposed within the space of the measuring unit cover 111 of the measuring device body 110; an illumination 152 for providing illumination light when capturing images of the sample cover disposed within the space of the measuring unit cover 111 of the measuring device body 110; and a storage unit 153 for storing images of the sample cover captured by the camera 151. The image management unit 150 functions to perform standardized image management based on the captured images, using both the camera 151 disposed within the measuring device body 110 and the illumination 152 disposed within the space of the measuring unit cover 111 of the measuring device body 110, under the same illumination light and at the same distance. In this case, the camera 151 may be located at the lower end of the front surface door 112, but is not limited to this; it can be understood as being located on the front surface opposite the location where the turbidity chart 120 is disposed, separated by the sample cover. Furthermore, the camera 151 and the turbidity chart 120 may be located between 80mm and 300mm apart, separated by the sample cover. And, as Figure 3 The illumination 152 may be composed of a pair of vertical rod-shaped LED lights that can provide the same illumination light to the space of the measuring part cover 111 of the measuring device body 110.

[0041] The control unit 160 is a structure for performing control management, which includes at least one function: driving control for contamination measurement of the laser optical sensor 130, display control of the display 140, and image management control of the image management unit 150. This control unit 160 can manage oil images and colors of various devices through a management program, including driving control for contamination measurement of the laser optical sensor 130, display control of the display 140, and image management control of the image management unit 150. The control unit 160 can output the results of particle contamination measurement in lubricating oil and hydraulic oil in document format, or transmit them to external instruments via wired or wireless means.

[0042] As described above, the visual turbidity measuring device 100 can perform a comparative analysis between visual confirmation of contamination based on the turbidity chart 120 and contamination measurement based on the laser optical sensor 130 when measuring particle contamination in lubricating oil and hydraulic oil. The visual turbidity measuring device 100 includes: a measuring device body 110, forming a measuring section outer cover 111 space for placing a sample outer cover that is sampled for measuring particle contamination in lubricating oil and hydraulic oil; and a turbidity chart 120, which is provided in a manner that enables confirmation and diagnosis of the contamination level of the sample outer cover placed in the measuring section outer cover 111 space of the measuring device body 110. A laser optical sensor 130 is used to measure the contamination level of a sample cover disposed in the space of the measuring unit cover 111 of the measuring device body 110; a display 140 is used to display the sample cover contamination level measurement result measured by the laser optical sensor 130 in a manner that allows confirmation; an image management unit 150 is used to capture images of the sample cover disposed in the space of the measuring device body 110 to store and manage them as oil images; and a control unit 160 is used to perform control management, the control management including at least one of the following functions: contamination level measurement drive control of the laser optical sensor 130, display control of the display 140, and image management control of the image management unit 150.

[0043] Furthermore, the visual turbidity measuring device 100 can promptly identify a malfunction of the laser optical sensor 130 by analyzing the interplay between visual measurements based on the turbidity chart 120 and contamination measurements based on the laser optical sensor 130. This turbidity measuring device 100 allows for easy visual confirmation and diagnosis, not only improving measurement reliability through dual measurement of electronic contamination levels but also enabling visual management as a fundamental aspect of lubrication management, meeting international standards by using the ASTM Bar Chart.

By controlling at least one of the functions of display control of the display and image management control of the shooting management unit, the present invention can realize the mutual comparative analysis between visual confirmation and diagnosis based on turbidity charts and electronic contamination measurement based on laser optical sensors.

This allows for both simple usage and visual management as a basic lubrication management method. Furthermore, by realizing the mutual comparative analysis between visual confirmation and diagnosis based on turbidity charts and electronic contamination measurement based on laser optical sensors, dual measurement of contamination, both visual and electronic, enables intuitive measurement by managers and further improves measurement accuracy.
