Description

Technical Field

[0001] This utility model relates to the technical field of fault diagnosis simulation devices, specifically a fault diagnosis simulation device for oil monitoring. Background Technology

[0002] The hydraulic failure simulation training bench (hereinafter referred to as the "bench") consists of a hydraulic system, a rotating load, and other components. The main function of the test bench is to simulate the hydraulic power system of equipment, used for related teaching experiments to study the performance of lubricating oil, sampling methods and techniques for in-use oils, their impact on equipment, and related fault diagnosis. The hydraulic system consists of an 80L oil tank, a screw pump, a heating system, and an oil cooler. The hydraulic system has a maximum adjustable flow rate of 22L / min, a maximum adjustable pressure of 3MPa, a total power of approximately 8KW, and an adjustable oil temperature range of room temperature to 60℃.

The online hydraulic monitoring device consists of hardware and monitoring software, integrating a lubrication monitoring sensor, an oil circulation system, a communication unit, and monitoring software, used for lubrication monitoring of the bench's hydraulic system and analysis of machine wear patterns.

[0003] In practical applications, oil from the tank is delivered to the load gearbox by opening a flow valve. The motor drives the gears, and in actual operation, the oil needs to flow through the friction of the meshing gears to simulate real-world equipment operation. However, because the oil currently enters the load gearbox directly instead of flowing onto the gear teeth, the test and experimental results may not accurately reflect actual wear conditions, affecting the accuracy and reliability of wear test data. Furthermore, the oil flowing to the outside of the gears makes flow rate uncontrollable, potentially leading to unstable flow and failing to meet the lubrication system's needs. Excessive flow can also result in oil waste. Summary of the Invention

[0044] Depend on Figure 1-4As shown, the similarities between this embodiment and Embodiment 1 will not be repeated here. The difference lies in that: one end of the load gearbox 202 is provided with a reciprocating piston test chamber assembly 400.

[0045] The oil monitoring system of this application includes an online oil monitoring device and a portable intelligent ferrography analyzer. The online oil monitoring device consists of hardware equipment and monitoring software. The instrument integrates a lubrication monitoring sensor, an oil circulation system, a communication unit, and a monitoring software system. It is used for lubrication monitoring of the bench hydraulic system and machine wear particle spectrum analysis. The online oil monitoring device can directly detect the moisture content and the number of wear particles of different sizes in the oil in the hydraulic system in real time. The portable ferrography analyzer is used to quickly detect the content and size of metal wear particles in the sample and extract typical images.

[0046] How this application works:

[0047] Inject oil into oil tank 104 and ensure that the oil reaches the appropriate level. Set the temperature of the heating system according to the experimental requirements so that the oil can start circulating at the required temperature. Start the screw pump, and the oil begins to flow and is transported through the pipeline. Servo motor 204 drives the second gear 206 to rotate, thereby driving the first gear 205 to work, simulating the mechanical load in the hydraulic system. Under the control of the motor, the rotation speed and load level of the load gearbox 202 can be adjusted to simulate the working state under different load conditions. Under the load generated by the load gearbox 202, the oil flows through the flow pipe 209 and is further transmitted through the connected delivery pipe 210. The flow of oil in the delivery pipe 210 is controlled by the regulating valve plate 217. The rotation of the regulating valve plate 217 can affect the flow rate of the oil. The rotating rod 216 is driven by the micro motor 214 to adjust the rotation angle of the regulating valve plate 217. By adjusting the position of the regulating valve plate 217, the flow rate of the oil can be changed. The linkage between the rotating rod 216 and the regulating valve plate 217 can precisely control the flow of oil in the dynamic process. The connecting valve 211 is connected to the first valve 106 of the oil tank 104. When the flow pipe 209 is above the first gear 205 and the second gear 206, the oil can flow precisely onto the teeth of the gears.

[0048] By activating the telescopic hydraulic cylinder 301, the telescopic guide rod 302 is hydraulically driven to move the scraper 304 up and down. The scraper 304 slides along the inner wall of the oil tank 108, removing impurities or deposits from the inner wall of the oil tank 108. The internal condition of the oil tank 108 is observed through the first transparent cover 105 to monitor the cleaning process. If impurities are found to have accumulated in a certain area, it may be necessary to adjust the position of the scraper 304 or the working state of the hydraulic cylinder.

[0049] When the equipment needs to be moved, the operator starts the adjusting motor 502. The motor starts to rotate, driving the threaded rod 503 to rotate. The rotation of the threaded rod 503 causes the adjusting moving cylinder 506 to slide up and down. The rotation speed and direction of the adjusting motor 502 determine the lifting speed and direction of the moving cylinder. The adjusting moving cylinder 506 slides up and down inside the stand 505 to adjust the height or position of the component. The heavy-duty rollers 508 enable the fault diagnosis simulation mechanism 100 to move smoothly to the new position.
