[0043] Example 5 On the basis of Example 2, an intelligent control detection module is further provided, and the intelligent control detection module includes: A speed sensor, used to detect the speed value of the drive motor 302 in real time; Temperature detection unit 1, used for real-time detection of the operating temperature value of the drive motor 1 302; The second temperature detection unit is used to detect the temperature value of the ambient air inside the active sealing mechanism 5; Density sensor, used to detect the density value of the test rubber ring; Thickness sensor, used to detect and record the thickness value of the test rubber ring in real time; Alarm, used to give an alarm in case of abnormal situation; Timer, used to record the detection time.
[0044] A first calculation unit calculates a deviation evaluation value between a preset rotation wear rate and an actual rotation wear rate of the test rubber within a detection period based on data from the rotation speed sensor, the temperature detection unit 1, the temperature detection unit 2, the density sensor, and the thickness sensor; A control unit is used to collect and process the data of each detection unit and sensor, and then adjust and correct the speed of the drive motor 302 and the ambient temperature. The control unit is electrically connected to the speed sensor, the temperature detection unit 1, the temperature detection unit 2, the density sensor, the thickness sensor and the alarm respectively; The judgment processing unit is used to compare and judge whether the deviation evaluation value between the preset rotation speed wear rate and the actual rotation speed wear rate in the detection time period is within a preset threshold range.
[0045] The first calculation unit is calculated based on the following formula: ;in: for The deviation evaluation value between the preset revolution wear rate and the actual revolution wear rate of the test rubber during the test period. for Preset test rubber wear quality within the test period, is the initial mass of the test rubber, is the actual mass of the tested rubber at time t, is the preset speed value of the driving motor 1 302, is the speed value of the driving motor 302 detected by the speed sensor at time t, is the density value of the wear test rubber detected by the density sensor, For the temperature detection unit The temperature value of the driving motor 302 detected at all times, is the temperature value of the driving motor 302 detected by the temperature detection unit 1 at time t, For temperature detection unit 2 The average temperature value of the ambient air inside the active sealing mechanism 5 detected during the detection period, N is the temperature of the thickness sensor at The total number of times the test rubber thickness is tested within the test time period, i is the number of the i-th test thickness, For The thickness value of the test rubber detected by the thickness sensor for the i-th time within the detection time period, is the initial thickness of the test rubber detected by the thickness sensor, The total wear time of the preset test rubber is: The detection end time recorded by the timer, is the initial detection time recorded by the timer, For the temperature detection unit The maximum operating temperature of the drive motor detected during the detection period, Temperature detection unit three The minimum operating temperature of the drive motor detected during the detection period; is a logarithmic function, The value of the natural constant is 2.72; is the specific heat capacity of ambient air.
[0046] The judgment processing unit performs comparative judgment. When the evaluation value of the deviation between the preset number of revolutions wear rate and the actual number of revolutions wear rate of the test rubber is less than the preset threshold range, the control unit increases the frequency of the driving motor 302, increases its rotation speed to correct the deviation, and simultaneously increases the temperature of the ambient air inside the active sealing mechanism 5. When the evaluation value of the deviation between the preset number of revolutions wear rate and the actual number of revolutions wear rate of the test rubber is within the preset threshold range, the expected wear effect of the wear test is met. When the evaluation value of the deviation between the preset number of revolutions wear rate and the actual number of revolutions wear rate is greater than the preset threshold, the control unit drives the frequency of the motor 302, reduces its rotation speed to correct the deviation, and simultaneously reduces the temperature of the ambient air inside the active sealing mechanism 5. When the evaluation value of the deviation between the preset number of revolutions wear rate and the actual number of revolutions wear rate of the test rubber still exceeds the preset threshold range after adjustment, the control unit turns off the driving motor 302 and controls the alarm to sound an alarm, notifying the maintenance personnel to perform maintenance inspections.
[0047] The working principle and beneficial effects of the above technical solution are: Working principle: When the device of the present invention is running, the preset speed of the driving motor 302 may deviate from the actual speed due to the lack of lubricating oil or the influence of dust and impurities in the environment, thereby causing a deviation between the preset speed wear rate of the test rubber and the actual speed wear rate. At the same time, the change of working temperature and ambient temperature may also cause the test to fail to meet the expected results.
[0048] Therefore, by adding an intelligent control and detection module, comprehensive monitoring and intelligent adjustment of the wear test process can be achieved. The integration of components such as speed sensor, temperature detection unit, density sensor, thickness sensor, etc. provides rich data support for the wear test. Based on these data, the first calculation unit calculates the deviation evaluation value between the preset rotation wear rate and the actual rotation wear rate of the test rubber, providing a basis for subsequent adjustments. The control unit automatically adjusts the parameters such as the speed of the drive motor 302 and the ambient temperature according to the judgment result of the judgment processing unit to correct the deviation. When the deviation exceeds the preset threshold, the alarm will sound an alarm in time to notify the maintenance personnel to perform maintenance inspections.
[0049] When the judgment processing unit makes a comparative judgment, when the deviation evaluation value between the preset revolution wear rate and the actual revolution wear rate of the test rubber is less than the preset threshold range, the control unit increases the frequency of the driving motor 302, increases its rotation speed to correct the deviation, and increases the temperature of the ambient air inside the active sealing mechanism 5 at the same time. When the deviation evaluation value between the preset revolution wear rate and the actual revolution wear rate of the test rubber is within the preset threshold range, the expected wear effect of the wear test is met. When the deviation evaluation value between the preset revolution wear rate and the actual revolution wear rate is greater than the preset threshold, the control unit drives the frequency of the motor 302, reduces its rotation speed to correct the deviation, and reduces the temperature of the ambient air inside the active sealing mechanism 5 at the same time. When the deviation evaluation value between the preset revolution wear rate and the actual revolution wear rate of the test rubber still exceeds the preset threshold range after an adjustment, the control unit turns off the driving motor 302 and controls the alarm to alarm, notifying the maintenance personnel to perform maintenance inspection. This technical solution significantly improves the automation level and intelligence level of the wear test, reduces the error caused by human operation, and ensures the accuracy and reliability of the test results.
[0050] Beneficial effects: The setting of the intelligent control detection module realizes real-time monitoring and intelligent adjustment of test parameters, and improves the accuracy and stability of the test. By comparing and judging the deviation evaluation value of the preset speed wear rate and the actual speed wear rate, problems are discovered and measures are taken in time to avoid deviations in test results. By alarming and shutting down the drive motor 302, the safety and reliability of the test are improved, and the safety of equipment and personnel is protected. The formula calculation comprehensively considers multiple factors, improves the accuracy of wear rate evaluation, and provides a scientific basis for optimizing wear tests.
