Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of corrosion resistance detection tools, in particular to a corrosion resistance detection device for an electronic pump rotor core. Background Art
[0002] As key equipment in the field of fluid transportation, electronic pumps are widely used in industries such as automobiles, chemicals, and medical equipment. Their operating efficiency and service life directly depend on the performance of core components. The rotor core, as the core component of the electronic pump, plays an important role in transmitting power and maintaining stable operation of the rotor. Since electronic pumps often work in environments containing corrosive media such as acids, alkalis, and water vapor, the rotor core is in contact with these media for a long time and is prone to corrosion, resulting in rust and peeling on the core surface, and even causing problems such as reduced structural strength and unbalanced operation. In severe cases, the electronic pump will be shut down and the equipment will be damaged, resulting in huge economic losses and safety hazards. Therefore, accurate testing of the corrosion resistance of the electronic pump rotor core is a key link to ensure the long-term stable operation of the electronic pump. While some testing equipment can achieve a certain degree of environmental simulation, they suffer from poor sealing performance. During the testing process, corrosive gases or solutions are prone to leakage, which not only pollutes the testing environment and endangers the health of operators, but also affects the reliability of test data due to changes in medium concentration. In addition, the detection dimensions of existing equipment are relatively single, and most can only test a single corrosive medium or fixed environmental conditions. In actual applications, rotor cores often face the synergistic effects of multiple corrosion factors, making it difficult for test results to fully reflect the core's corrosion resistance and unable to meet the needs of high-precision, multi-scenario testing. Therefore, the above problems need to be improved. Summary of the Invention

This ultimately solves the problems of poor sealing performance, single testing conditions, and low adaptability of iron core placement in existing devices. The analysis module uses a closed-loop logic of image grayscale analysis, corrosion area location, and quantitative boost adjustment to identify the deviation between the spray coverage area and the core contour in real time. It then precisely controls the boost pipe pressure to ensure that the spray coverage width matches the core size, avoiding "low spray volume at the core edge" or "liquid accumulation in the center" due to improper pressure. This prevents "misjudgment of local corrosion resistance" and ensures that the test data is more consistent with the core's actual corrosion resistance. The servo motor drives the storage plate to rotate around the axis, ensuring that multiple iron cores pass through the spray area in sequence. At the same time, the clamping plate engages with the internal gear ring through the gear, driving the iron core itself to rotate during the revolution, so that the iron core contacts the atomized liquid 360° without dead angles. Precise pressure regulation avoids excessive spraying and reduces reagent waste. Multiple iron cores are tested in the same environment to ensure the consistency of batch data, improving the comparability and credibility of batch data. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Working principle: When using the present invention, first power on the device and turn on all electrical appliances. By manipulating the central console 3, control the electric push rod 10 to extend, thereby driving the machine cover 4 to open, install the storage rod 20 and the V-shaped storage plate 21 through the first slide groove and the second slide groove, place the detection part on the storage rod 20 and the V-shaped storage plate 21, and then close the machine cover 4. During this process, since the sealing strip material is plastic, there is no need to worry about the arc motion trajectory affecting the sealing strip entering the sealing groove. At the same time, the solution filling port 11 adds the mixed acid solution to the first acid-proof Inside the tube, the bubbling tower 12 simultaneously inputs the gas containing the reagent into the first acid-proof tube, mixes it through the mixing valve 13, and divides it into two tubes through the diverter valve. It is then pressurized through the pressure tube 14, and the acid solution is sprayed onto the test piece through the atomizer 15. At the same time, the heating plate 16 heats it, and cooperates with the humidity sensor 22 and the temperature sensor 23 to simulate the real environment. The corrosion of the test piece can be observed by the naked eye through the transparent glass 7. At the same time, the collecting cup 19 collects the acid solution inside the chassis 2, and its acidity is tested by the acid detector 17 to ensure the accuracy of the test.
[0021] Example 2: See Figures 5 and 6 , the central console 3 is provided with an intelligent control component, which includes an acquisition module, an analysis module and an execution module; The acquisition module collects image data of the atomized spray area, the length and width data of the rotor core, and the boost amplitude data of the boost spray, and transmits the collected data to the analysis module; The analysis module receives the data transmitted by the acquisition module, pre-processes the data, processes and segments the image grayscale, determines the location of concentrated corrosion, divides the area into regions, and compares the divided area with the contour shape of the rotor core. If the divided area is small, it generates a boost signal and transmits the boost signal to the execution module. The change value caused by a single boost is obtained based on the single boost amplitude, and the boost amplitude data is analyzed. Sort the collected data by collection time, and sort the corresponding items collected at the same time average the data and standard deviation Calculation, and the calculated mean and standard deviation Collect data fluctuation range for corresponding items The setting of the corresponding item is to compare the collected data with the fluctuation range of the corresponding item, mark the corresponding item data that is not within the fluctuation range as an outlier, and record the number of outliers ,like , then the collected data is judged to be abnormal and the data is re-tested. is the preset proportional coefficient; if , then remove the outliers and average the remaining corresponding test data after removing the outliers Calculation, and the calculated mean as corresponding item data detected at the corresponding moment; The value of needs to be dynamically adjusted in combination with "collection data type", "device accuracy" and "detection scenario requirements", and there is no universal fixed value; the higher the device accuracy, the smaller the fluctuation of normal data and the lower the proportion of abnormal values. It can be set more strictly; for example, for a 2-megapixel industrial camera (image grayscale value error ±2), a PT1000 temperature sensor (error ±0.1°C), the normal abnormal value ratio is <3%, Set to 0.03; Re-check the corresponding data. If the comparison result is still , it is determined that there is an abnormality in the acquisition device, a device warning signal is generated, and the device warning signal is transmitted to the execution module; After receiving the equipment warning signal, the execution module controls the buzzer module of the intelligent control component to issue a buzzer warning and displays "acquisition equipment abnormality" on the central console 3, so that the staff can carry out timely maintenance operations on the equipment in a timely manner.
[0022] The adjustment mechanism includes a storage plate 21. A rotating shaft is installed below the corresponding storage plate 21 inside the chassis 2. An outer gear ring is provided on the outer wall of the rotating shaft. A servo motor is provided at the position corresponding to the outer gear ring inside the chassis 2. The gear installed on the output end of the servo motor is engaged with the outer gear ring, so that the servo motor drives the rotating shaft to rotate. A plurality of storage plates 21 are evenly installed on the outside of the rotating shaft through a connecting frame. Adjacent storage plates 21 are tightly attached to each other so that the liquid sprayed by the atomizer 15 will not cause corrosion to the lower structure. Limiting grooves 2 are provided at the upper and lower positions on both sides of the inner wall of the storage plate 21. 5. A clamping plate 24 is slidably connected to the inner side of the storage plate 21 at the position corresponding to the limit groove 25. Slide plates are integrally formed on both sides of the clamping plate 24 at the position corresponding to the limit groove 25. A rectangular groove is opened in the middle position of the upper and lower surfaces of the slide plates. Rectangular strips of the same size are integrally formed at the position corresponding to the rectangular groove on the upper and lower inner walls of the limit groove 25. When the clamping plate 24 slides inside the limit groove 25, due to the mutual restriction of the rectangular strip and the rectangular groove, it always remains perpendicular to the storage plate 21. A baffle 26 is slidably connected to the upper side of the storage plate 21 inside the chassis 2 through the sliding groove. The clamping plate 24 is 7-shaped and is divided into a blocking structure at the upper end and a rotating structure at the lower end. The blocking structure prevents the clamped object from falling during the rotation process. The rotating structure extends to the outside of the storage plate 21 through the rotating shaft, and a gear is also installed on one end of the rotating shaft extending to the outside of the storage plate 21. An internal gear ring is provided on the inner wall of the chassis 2 at a position corresponding to the storage plate 21. The internal gear ring and the gear on the rotating shaft engage with each other (ensuring that the bottom surface faces upward when the object is rotated to the upper position again). When the servo motor drives the storage plate 21 to rotate, the rotating structure of the clamping plate 24 drives the clamped object to rotate, so that when the storage plate 21 rotates around the rotating shaft, the clamped object also rotates inside the storage plate 21. A spraying test is conducted, in which the same test plate is placed on both sides of the atomizer 15 meters away, and atomization spraying is performed for a set time at an initial pressure. After the spraying is completed, an image of the test plate is collected, and the collected image data is gray-processed and segmented according to the pixel block size. The image blocks formed after segmentation are numbered according to the number of rows and columns in which they are located, and gray-scale value data of the image blocks with corresponding numbers are collected. The image blocks with gray-scale value data within the preset gray-scale value range are marked as corrosion hole image blocks; the distance between adjacent corrosion hole image blocks is calculated. , will satisfy The image blocks are color-marked, and the areas covered by the color-marked image blocks are marked. is the preset distance threshold; a rectangular figure corresponding to the rotor core is drawn on the grayscale image, and the drawn rectangular figure is compared with the marked coverage area. If the length or width of the rectangular figure is greater than the marked coverage area, a boost signal is generated and transmitted to the execution module, and the length difference is calculated. and width difference ; The grayscale value range is preset. The surface of an uncoated bare metal core (such as a silicon steel sheet) has a metallic luster, and the grayscale value in the normal area is generally 80-120 (medium brightness). If the core surface has an anti-rust coating (such as an epoxy coating), the grayscale value in the normal area will increase to 100-150 (the coating is more reflective). However, the grayscale value in the corroded area will significantly deviate from the normal range due to the presence of "holes and rust." If a high-resolution industrial camera (such as a 2-megapixel camera) is used and the lighting inside the chassis is uniform (through diffuse reflection from transparent glass 7), the grayscale value in the normal area will fluctuate slightly (±5), and the range can be set narrower. If the lighting is uneven or the camera resolution is low, the range needs to be widened to avoid missed detections. Select a standard part with the same material and surface condition as the core to be tested, and artificially create different degrees of corrosion. Place the standard part in chassis 2, capture images according to the normal testing process, and perform grayscale processing. Use image analysis software to measure the grayscale values of the "normal area" and "corroded area", and use the "minimum grayscale value of the corroded area -5" to "maximum grayscale value of the corroded area +5" as the preset range (for example, the grayscale of the corroded area of the standard part is 25-55, and the preset range is 20-60). Use this range to test 1-2 groups of cores to be tested. If there is a missed detection (normal area is marked) or a false detection (corroded area is not marked), fine-tune the range by ±5-10 until the accuracy rate is ≥95%; Select 3-5 iron cores to be tested with different corrosion distributions; observe and manually mark the actual corrosion range on the iron core surface through the transparent glass 7, and measure the maximum distance between adjacent corrosion points; take "the maximum distance between adjacent corrosion points marked manually + 1-2mm" as the initial ; Use the Let the analysis module automatically divide the coverage area, compare the "automatic division results" with the "manual marking results", if the overlap is ≥ 90%, then Suitable; if the overlap is low, fine-tune ±1-2mm until it meets the standard; The single boost amplitude is , amplify twice, compare the rectangular figure with the coverage area after supercharging, and calculate the length difference 、 and width difference 、 ; Calculate the length change 、 and width variation , ; The mean of the changes is taken as the change value caused by a single boost, that is, the change value , change value , determine the adjustment range of length and width of a single boost and , adjustment range ; Initial pressure of the device Usually it is set according to the performance of the atomizer 15; set the chassis 2 to a constant temperature and humidity (such as 25°C, 85%RH), install a standard test board (the size is consistent with the iron core to be tested); Start by increasing each time (such as 0.01MPa), record the spray coverage width after each pressure increase, and calculate the ratio of "pressure change - coverage width change" (i.e. sensitivity); if the sensitivity is high (such as 0.01MPa→+0.5mm), take 0.02MPa (2 times the sensitivity step); if the sensitivity is low (0.05MPa→+0.5mm), take 0.03MPa (slightly smaller than the sensitivity step to avoid insufficient adjustment); pressurize twice according to K1 step (such as 0.03MPa, from 0.2→0.23→0.26MPa), calculate the length / width change ( 、 ), if the variation is stable (e.g. 0.3mm, 0.28mm), then Suitable; if the change is large (such as 0.5mm, 0.1mm), fine adjustment 0.01MPa; After receiving the boost signal, the execution module obtains the adjustment amplitude obtained by the analysis module and adjusts the pressure according to the adjustment amplitude.
[0023] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
