Description

Technical Field

[0001] The present invention relates to the technical field of seal detection, and more specifically, to a seal detection method and system for a six-sided top press. Background Art

[0002] In the field of industrial production, as a core device in key links such as superhard material synthesis and high-pressure scientific research, the sealing performance of a six-sided top press is directly related to production safety, product quality, and economic benefits. With the continuous growth of the demand for superhard materials (such as synthetic diamonds, cubic boron nitrides, etc.) in modern industry, the application of six-sided top presses is becoming more and more extensive, and higher requirements are also placed on the stability and reliability of equipment operation.

[0003] Traditional seal detection methods for six-sided top presses mostly rely on the experience judgment of operators or single pressure test methods. For example, by visually inspecting whether there are obvious damages on the sealing surface, or only observing the pressure change within a short period after pressurization to evaluate the sealing performance. Such methods have many limitations: Visual inspection is difficult to detect potential defects such as micro-cracks and wear, and it is impossible to quantitatively evaluate the integrity of the sealing surface; a single pressure test cannot accurately reflect the actual performance of the sealing structure under long-term high-pressure conditions, and it is prone to missed inspections or misjudgments, resulting in the equipment running with "problems". Once the seal fails, it will not only cause production interruption and product scrapping, but may also lead to the leakage of high-temperature and high-pressure media, and even cause serious safety accidents such as explosions. In addition, with the development of six-sided top presses towards large-scale and high-precision directions, their sealing structures are becoming increasingly complex, and traditional detection methods are no longer able to meet the strict requirements of modern industrial production for equipment reliability and safety.

[0004] Therefore, it is necessary to provide a seal detection method and system for a six-sided top press to solve the problem of inaccurate and incomplete seal detection of six-sided top presses in the prior art. Summary of the Invention

[0005] In view of this, the present invention proposes a seal detection method and system for a six-sided top press, aiming to solve the problem of inaccurate and incomplete seal detection of six-sided top presses in the prior art.

[0006] On the one hand, the present invention proposes a seal detection method for a six-sided top press, including: Pre-treat the sealing surface of the six-sided top press, collect the image information of the sealing surface, and initially obtain the integrity index of the sealing surface according to the image information; Install a pressure sensor on the sealing surface, start the six-sided top press, increase the pressure to the set pressure value, collect the pressure information of the pressure sensor, and initially score the sealing performance according to the pressure information; Keep the set pressure value unchanged, collect pressure information at fixed time intervals, calculate the pressure change value between the pressure information, and determine whether to correct the preliminary seal performance score according to the pressure change value; If it is determined that the preliminary seal performance score needs to be adjusted, calculate a correction factor according to the pressure change value, and correct the preliminary seal performance score according to the correction factor to obtain the final seal performance score; Perform safety warning on the six-sided top press according to the integrity index and the final seal performance score.

[0007] Further, when collecting the image information of the seal surface and initially obtaining the integrity index of the seal surface according to the image information, it includes: Extract scratches and wear in the seal surface image information, calculate the total area of scratches and wear, and record it as the damaged area; Set a damage limit threshold. If the damaged area is zero, the integrity index is 1; If the damaged area is greater than zero and less than the damage limit threshold, the integrity index is the first index; If the damaged area is greater than or equal to the damage limit threshold, the integrity index is the second index; Among them, 1 > the first index > the second index. If the integrity index is the second index, directly perform a danger warning and stop the seal detection of this seal surface.

[0008] Further, when installing a pressure sensor on the seal surface, starting the six-sided top press, increasing the pressure to the set pressure value, collecting the pressure information of the pressure sensor, and performing a preliminary seal performance score according to the pressure information, it includes: A number of pressure sensors are provided. Collect the pressure information of all pressure sensors. If all the pressure information is equal to the set pressure value, the preliminary seal performance score is the first score; If there is pressure information less than the set pressure value in the pressure information, the preliminary seal performance score is the second score; The first score is the full score, and the first score is greater than the second score.

[0009] Further, when keeping the set pressure value unchanged, collecting pressure information at fixed time intervals, and calculating the pressure change value between the pressure information, it includes: Preset the acquisition duration, and collect pressure information at fixed time intervals within the acquisition duration; Taking the same pressure sensor as a unit and constructing a pressure sequence in the order of time; Calculate the pressure change value of the pressure information in each pressure sequence and construct a pressure change sequence.

[0010] Furthermore, the determining whether to revise the preliminary sealing performance score according to the pressure change value includes: If all parameters in the pressure change sequence are zero, it is determined that the preliminary sealing performance score will not be corrected; Otherwise, it is determined that the preliminary sealing performance score needs to be revised.

[0011] Furthermore, if it is determined that the preliminary sealing performance score needs to be adjusted, the correction factor is calculated according to the pressure change value, including: Obtaining a total number of pressure change values greater than zero in all pressure change sequences, setting a number threshold, and determining an initial value of the correction factor as a first correction factor if the total number of changes is less than the number threshold; and determining an initial value of the correction factor as a second correction factor if the total number of changes is greater than or equal to the number threshold; Obtaining a maximum value of the pressure change value and setting a change threshold; if the maximum value of the change is less than the change threshold, not adjusting the initial value of the correction factor, and using the initial value of the correction factor as the final value of the correction factor; if the maximum value of the change is greater than or equal to the change threshold, adjusting the change threshold by an adjustment coefficient to obtain a final value of the correction factor; Wherein, 1>adjustment coefficient>0, the final value of the correction factor is the product of the initial value of the correction factor and the adjustment coefficient.

[0012] Furthermore, the step of correcting the preliminary sealing performance score according to the correction factor to obtain a final sealing performance score includes: The final sealing performance score is the product of the preliminary sealing performance score and the correction factor; The correction factor has a value range of 1>correction factor>0.

[0013] Furthermore, when providing a safety warning to the six-sided top press according to the integrity index and the final sealing performance score, the method includes: Set sealing performance score limit values; If the integrity index is 1 and the final value of the sealing performance score is greater than the sealing performance score limit value, no warning is issued; If the integrity index is the first index and the final value of the sealing performance score is greater than the sealing performance score limit value, a first-level warning is issued; If the integrity index is 1, and the final value of the sealing performance score is less than or equal to the sealing performance score limit value, a second-level warning is issued; If the integrity index is the first index and the final value of the seal performance score is less than or equal to the seal performance score limit value, a third-level warning is issued. The warning levels are, from low to high, the first-level warning, the second-level warning, and the third-level warning.

[0014] Furthermore, when preprocessing the sealing surface of the six-sided top press, it includes: Disconnect all power connections of the six-sided top press; Clean the sealing surface of the six-sided top press to remove impurities and foreign objects on the surface of the sealing surface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the initial stage of detection, by preprocessing the sealing surface and collecting images to obtain the integrity index, physical damages such as scratches and abrasions on the sealing surface can be visually discovered before the equipment runs, potential risks can be identified in a timely manner, and subsequent detection misjudgments or equipment operation failures caused by sealing surface defects can be avoided, reducing maintenance costs and safety hazards. In the pressure detection link, first, the basic condition of the seal is quickly judged by the preliminary seal performance score, and then the score is corrected by collecting pressure information at intervals and calculating the change value. This dynamic monitoring and adjustment mechanism fully considers the actual changes in pressure during the pressure holding process, making the final value of the seal performance score more accurately reflect the seal performance. Compared with a single detection method, the reliability of the detection result is greatly improved. Finally, safety warnings are issued by comprehensively considering the integrity index and the final value of the seal performance score, constructing a multi-dimensional evaluation system, which can divide the warning levels according to different combination situations, providing clear and targeted risk prompts for operators, enabling them to take maintenance or emergency measures in a timely manner, ensuring the safe and stable operation of the six-sided top press, improving production efficiency and product quality, and being of great significance to the safety management and efficient operation of industrial production.

[0016] On the other hand, the present application also provides a seal detection system for a six-sided top press, including: An integrity evaluation module, configured to preprocess the sealing surface of the six-sided top press, collect image information of the sealing surface, and initially obtain an integrity index of the sealing surface according to the image information; A seal performance preliminary analysis module, configured to install a pressure sensor on the sealing surface, start the six-sided top press, increase the pressure to a set pressure value, collect pressure information of the pressure sensor, and perform a preliminary seal performance score according to the pressure information; A seal performance correction module, configured to keep the set pressure value unchanged, collect pressure information at fixed intervals, calculate the pressure change value between the pressure information, and judge whether to correct the preliminary seal performance score according to the pressure change value; The sealing performance correction module is further configured to calculate a correction factor based on the pressure change value if it is determined that the preliminary sealing performance score needs to be adjusted, and correct the preliminary sealing performance score according to the correction factor to obtain the final value of the sealing performance score; An early warning module, configured to perform safety early warning on the six-sided top press according to the integrity index and the final value of the sealing performance score.

[0017] It can be understood that the sealing detection method and system for a six-sided top press provided in this application have the same beneficial effects and will not be elaborated here. Description of the Drawings

Detailed Embodiments

[0019] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0020] In some embodiments of the present application, referring to Figure 1 As shown, this embodiment provides a sealing detection method for a six-sided top press, including the following steps: S100. Pretreat the sealing surface of the six-sided top press, collect the image information of the sealing surface, and initially obtain the integrity index of the sealing surface according to the image information; S200. Install a pressure sensor on the sealing surface, start the six-sided top press, increase the pressure to a set pressure value, collect the pressure information of the pressure sensor, and perform a preliminary sealing performance score according to the pressure information; S300. Keep the set pressure value unchanged, collect pressure information at fixed time intervals, calculate the pressure change value between the pressure information, and determine whether to correct the preliminary seal performance score according to the pressure change value; S400. If it is determined that the preliminary seal performance score needs to be adjusted, calculate a correction factor according to the pressure change value, and correct the preliminary seal performance score according to the correction factor to obtain the final seal performance score; S500. Conduct a safety warning for the six-sided top press according to the integrity index and the final seal performance score.

[0021] It can be understood that in the initial stage of detection of the present invention, by preprocessing the seal surface and collecting images to obtain the integrity index, physical damages such as scratches and abrasions on the seal surface can be visually discovered before the equipment runs, potential risks can be identified in time, subsequent detection misjudgment or equipment operation failures caused by seal surface defects can be avoided, and maintenance costs and safety hazards can be reduced. In the pressure detection link, first quickly judge the basic condition of the seal with the preliminary seal performance score, and then correct the score by collecting pressure information at intervals and calculating the change value. This dynamic monitoring and adjustment mechanism fully considers the actual change of pressure during the pressure holding process, making the final seal performance score more accurately reflect the seal performance. Compared with a single detection method, the reliability of the detection result is greatly improved. Finally, a safety warning is conducted by comprehensively considering the integrity index and the final seal performance score, constructing a multi-dimensional evaluation system, which can divide the warning level according to different combination situations, provide clear and targeted risk prompts for operators, enabling them to take maintenance or emergency measures in time, ensuring the safe and stable operation of the six-sided top press, improving production efficiency and product quality, and having important significance for the safety management and efficient operation of industrial production. Specifically, the seal surface includes the connection between the pressure cylinder and the pressure head, the contact parts between the periphery of the synthesis cavity and each anvil, and the pipeline interface.

[0022] In some embodiments of the present application, when collecting the image information of the seal surface and initially obtaining the integrity index of the seal surface according to the image information, it includes: Extract scratches and abrasions in the seal surface image information, calculate the total area of scratches and abrasions, and record it as the damaged area; Set a damage limit threshold. If the damaged area is zero, the integrity index is 1; If the damaged area is greater than zero and less than the damage limit threshold, the integrity index is the first index; If the damaged area is greater than or equal to the damage limit threshold, the integrity index is the second index; Among them, 1> the first index> the second index. If the integrity index is the second index, a danger warning is directly issued and the sealing detection of the sealing surface is stopped.

[0023] It can be understood that the sealing surface integrity index evaluation method of the present invention converts image information into intuitive numerical indicators by quantifying the damage area, providing a scientific and efficient pre-judgment basis for sealing performance testing. On the one hand, using the damage area as the core evaluation factor can accurately capture the physical defects of the sealing surface, greatly reducing the misjudgment rate compared to manual subjective judgment, and ensuring the accuracy and reliability of the test results; on the other hand, different integrity index levels are set according to the damage area, so that the sealing surface condition is clearly graded, especially when the integrity index is the second index, it immediately triggers a danger warning and terminates the test, effectively avoiding equipment failures or even safety accidents that may be caused by serious damage to the sealing surface, achieving early intervention and active prevention and control of risks, and significantly improving the safety and effectiveness of the detection process.

[0024] Specifically, a high-definition industrial camera captured images of the sealing surface, and image analysis software identified numerous minor scratches and localized wear on the surface, calculating the damage area to be 8 square millimeters. Based on equipment operating parameters and historical experience, the company set a damage threshold of 3 square millimeters. Because 8 square millimeters exceeded the damage threshold, the sealing surface integrity index was determined to be the second highest. The system immediately issued a danger warning and halted further testing of the sealing surface. This prevented potential leakage accidents caused by sealing surface damage during equipment operation, ensuring production safety and stable equipment operation.

[0025] In some embodiments of the present application, the steps of installing a pressure sensor on the sealing surface, starting a six-sided press, increasing the pressure to a set pressure value, collecting pressure information from the pressure sensor, and performing a preliminary sealing performance score based on the pressure information include: There are a plurality of pressure sensors, and pressure information of all pressure sensors is collected. If all pressure information is equal to the set pressure value, the preliminary sealing performance score is the first score; If there is pressure information in the pressure information that is less than the set pressure value, the preliminary sealing performance score is the second score; The first score is a full score, and the first score is greater than the second score.

[0026] It is understandable that, firstly, the use of several pressure sensors enables comprehensive and multi-angle monitoring of pressure conditions at different locations on the sealing surface, greatly improving the comprehensiveness and accuracy of detection compared to a single sensor. Secondly, the scoring levels are divided according to the comparison between pressure information and set pressure values. The rules are clear and unambiguous, and easy to quantify and judge. When all pressure information reaches the set value, full marks are awarded, indicating good sealing performance; while any lack of pressure results in a lower score. This can promptly identify potential sealing problems, provide early warnings, avoid serious consequences caused by local sealing failure, and effectively ensure the safe and stable operation of the six-sided top press.

[0027] Specifically, six pressure sensors were evenly installed on the sealing surface of a certain press. After starting the press and increasing the pressure to the set pressure value of 100 MPa, pressure information was collected. The pressure values displayed by five of the sensors were stable at 100 MPa, but one sensor showed a pressure value of only 98 MPa. According to the scoring rules, the preliminary sealing performance score of the press was the second score. The staff immediately conducted a detailed inspection of the location and found that the sealing gasket was slightly damaged. After the gasket was replaced in time, the pressure values displayed by all sensors reached 100 MPa during re-testing. This test avoided production interruptions and product quality degradation caused by sealing problems, saving the company a lot of costs.

[0028] In some embodiments of the present application, the step of maintaining the set pressure value unchanged, collecting pressure information at fixed intervals, and calculating the pressure change value between the pressure information includes: Preset a collection time period, and collect pressure information at fixed intervals within the collection time period; Using the same pressure sensor as a unit and building a pressure sequence in time sequence; The pressure change value of the pressure information in each pressure sequence is calculated to construct a pressure change sequence.

[0029] In some embodiments of the present application, determining whether to revise the preliminary sealing performance score according to the pressure change value includes: If all parameters in the pressure change sequence are zero, it is determined that the preliminary sealing performance score will not be corrected; Otherwise, it is determined that the preliminary sealing performance score needs to be revised.

[0030] It is understandable that by presetting the collection time and collecting pressure information at fixed intervals, and constructing a pressure sequence and a pressure change sequence, we can systematically capture the performance evolution of the sealing surface under continuous pressure and avoid missing potential leakage risks due to short-term detection. By determining whether the pressure change sequence parameters are all zero, we can decide whether to correct the score, which can make the score accurate. When all the parameters are zero, it means that the pressure is stable and there is no obvious deterioration in the sealing performance; if there are non-zero parameters, it indicates that the pressure fluctuates and there is a possibility of leakage, and the score needs to be corrected in time. This mechanism effectively avoids the limitations of static preliminary scoring and provides a dynamic and accurate judgment basis for sealing performance evaluation, ensuring that the test results are highly consistent with the actual sealing status of the equipment, discovering and warning potential problems in advance, and ensuring the safe and stable operation of the six-sided top press.

[0031] Specifically, a six-sided top press is set up with a daily operating pressure of 80MPa. The collection time is set to 30 minutes during the test, and pressure information is collected every 5 minutes. In the preliminary sealing performance score, the pressure values of all pressure sensors reached the set values and received full marks. However, in the pressure change monitoring stage, taking sensor A as an example, the pressure sequence it constructed was [80MPa, 79.8MPa, 79.6MPa, 79.5MPa, 79.3MPa, 79.2MPa], and none of the parameters in the pressure change sequence were zero. According to the rules, it is judged that the preliminary score needs to be corrected, and the score is reduced by calculating the correction factor.

[0032] In some embodiments of the present application, if it is determined that the preliminary sealing performance score needs to be adjusted, calculating the correction factor according to the pressure change value includes: Obtaining a total number of pressure change values greater than zero in all pressure change sequences, setting a number threshold, and determining an initial value of the correction factor as a first correction factor if the total number of changes is less than the number threshold; and determining an initial value of the correction factor as a second correction factor if the total number of changes is greater than or equal to the number threshold; Obtaining a maximum value of the pressure change value and setting a change threshold; if the maximum value of the change is less than the change threshold, not adjusting the initial value of the correction factor, and using the initial value of the correction factor as the final value of the correction factor; if the maximum value of the change is greater than or equal to the change threshold, adjusting the change threshold by an adjustment coefficient to obtain a final value of the correction factor; Wherein, 1>adjustment coefficient>0, the final value of the correction factor is the product of the initial value of the correction factor and the adjustment coefficient.

[0033] In some embodiments of the present application, the correcting the preliminary sealing performance score according to the correction factor to obtain a final sealing performance score includes: The final sealing performance score is the product of the preliminary sealing performance score and the correction factor; Among them, the value range of the correction factor is 1 > correction factor > 0.

[0034] It can be understood that by obtaining the total number of changes greater than zero in the pressure change sequence and comparing it with the set quantity threshold, the frequency of pressure changes can be initially judged. If the total number of changes is small, it indicates that the pressure fluctuation is relatively small and the sealing performance is relatively stable. At this time, the adjustment range of the first correction factor for the preliminary score is small; on the contrary, if the total number of changes is large, it indicates that the pressure fluctuation is relatively frequent and there may be major hidden dangers in the sealing performance. Then the second correction factor will make a large adjustment to the preliminary score. At the same time, considering the relationship between the maximum change value and the change threshold in the pressure change value, the adjustment of the correction factor is further refined. When the maximum change value is small, the initial value of the correction factor is not adjusted, and a relatively stable score is maintained; when the maximum change value is large, the change threshold is adjusted through the adjustment coefficient to obtain the final value of the correction factor that more conforms to the actual situation, so that the final value of the sealing performance score can more accurately reflect the true sealing state of the equipment. This method comprehensively considers multiple dimensions of pressure changes, avoids the one-sidedness of single-factor judgment, makes the score correction more scientific and reasonable, helps to timely discover potential problems in the sealing performance, and provides a strong guarantee for the safe operation of the equipment.

[0035] Specifically, the set acquisition duration is 60 minutes, and the pressure information is acquired every 10 minutes, obtaining a total of 6 pressure change sequences. Among them, the total number of changes in the pressure change value greater than zero is 8 times, and the set quantity threshold is 5 times. Since the total number of changes is greater than the quantity threshold, the initial value of the correction factor is determined to be the second correction factor. Among these pressure change values, the maximum change value is 0.8 MPa, and the set change threshold is 0.5 MPa. Because the maximum change value is greater than the change threshold, the change threshold is adjusted by the adjustment coefficient of 0.6, and the final value of the correction factor is obtained by multiplying the second correction factor by 0.6. Assuming that the preliminary sealing performance score is 80 points, then the final value of the sealing performance score is 80 multiplied by the final value of the correction factor, that is, 80×(second correction factor×0.6). In this way, the enterprise can more accurately evaluate the sealing performance of the six-sided top press, timely discover and handle potential sealing problems, and ensure the safety and stability of the production process.

[0036] In some embodiments of the present application, when performing safety warning on the six-sided top press according to the integrity index and the final value of the sealing performance score, it includes: Set the sealing performance score limit value; If the integrity index is 1 and the final value of the sealing performance score is greater than the sealing performance score limit value, no warning is given; If the integrity index is the first index and the final value of the sealing performance score is greater than the sealing performance score limit value, a first-level warning is issued; If the integrity index is 1, and the final value of the sealing performance score is less than or equal to the sealing performance score limit value, a second-level warning is issued; If the integrity index is the first index and the final value of the sealing performance score is less than or equal to the sealing performance score limit value, a third-level warning is issued; The warning levels from low to high are level one warning, level two warning and level three warning.

[0037] It is understandable that, on the one hand, combining the integrity index with the final sealing performance score overcomes the limitations of single-indicator assessments, comprehensively assessing risks from two perspectives: the basic condition of the sealing surface and the actual pressure-bearing performance. This allows early warning results to better reflect the equipment's true state. On the other hand, by categorizing early warning levels and setting differentiated response strategies for different combinations, precise hierarchical risk management is achieved. This approach not only avoids the waste of resources caused by excessive early warnings, but also issues timely and accurate alarms when real risks exist, helping operators quickly determine the degree of risk and take targeted measures, effectively ensuring the operational safety and production stability of the six-sided top press.

[0038] Specifically, in a special ceramic production enterprise, during a regular inspection of a six-sided top press, the sealing surface was analyzed through image analysis, and due to slight wear, the integrity index was judged to be the first index; after pressure testing and score correction, the final sealing performance score was 75 points, and the set sealing performance score limit was 80 points, triggering a third-level warning.

[0039] In some embodiments of the present application, the pre-treatment of the sealing surface of the six-sided top press includes: Disconnect all power connections of the six-sided top press; Clean the sealing surface of the six-sided press and remove impurities and foreign matter on the sealing surface.

[0040] It is understandable that disconnecting all power connections can fundamentally eliminate the risk of electric shock to operators during the detection process, while avoiding electromagnetic interference to the detection equipment caused by live operation, and ensuring the accuracy of data obtained by detection instruments such as image acquisition devices. Cleaning the sealing surface to remove surface impurities and foreign objects can, on the one hand, avoid the influence of impurities on the image acquisition effect, prevent misjudgment of defects such as scratches and wear on the sealing surface caused by impurity interference, and ensure the reliability of the integrity index calculation; on the other hand, the presence of impurities may damage the flatness of the sealing surface and interfere with the pressure distribution, resulting in abnormal data during pressure detection. Cleaning the sealing surface can enable the pressure sensor to more truly reflect the sealing performance, avoid false detection and missed detection caused by impurities, lay a solid foundation for the subsequent sealing performance evaluation based on image analysis and pressure detection, and effectively improve the scientificity and effectiveness of the entire sealing detection process.

[0041] On the other hand, referring to Figure 2 As shown, the present application also provides a sealing detection system for a six-sided top press for applying the above-mentioned sealing detection method for a six-sided top press, including: An integrity evaluation module configured to preprocess the sealing surface of the six-sided top press, collect image information of the sealing surface, and preliminarily obtain an integrity index of the sealing surface according to the image information; A preliminary sealing performance analysis module configured to install a pressure sensor on the sealing surface, start the six-sided top press, increase the pressure to a set pressure value, collect pressure information of the pressure sensor, and perform a preliminary sealing performance score according to the pressure information; A sealing performance correction module configured to keep the set pressure value unchanged, collect pressure information at fixed time intervals, calculate the pressure change value between the pressure information, and determine whether to correct the preliminary sealing performance score according to the pressure change value; The sealing performance correction module is further configured to, if it is determined that the preliminary sealing performance score needs to be adjusted, calculate a correction factor according to the pressure change value, and correct the preliminary sealing performance score according to the correction factor to obtain a final sealing performance score; An early warning module configured to perform a safety early warning on the six-sided top press according to the integrity index and the final sealing performance score.

[0042] It can be understood that the integrity evaluation module of the present invention realizes the automation of sealing surface pretreatment and initial state evaluation, ensures the accuracy and consistency of basic data collection of sealing surface, and provides a reliable basis for subsequent detection; the sealing preliminary analysis module quickly completes pressure loading and preliminary performance scoring, efficiently screens out equipment with obvious sealing problems, and improves detection efficiency; the sealing correction module performs scoring correction based on dynamic pressure changes, deeply explores potential hidden dangers of sealing performance, and makes the detection results more in line with actual working conditions; the early warning module integrates the data of the previous module for graded early warning, and provides an intuitive and clear decision-making reference for equipment maintenance. The modules have clear division of labor and collaborative operation, which not only reduces the complexity and subjectivity of manual operation, but also realizes the standardization, systematization and intelligence of the detection process, effectively improving the accuracy, efficiency and reliability of the six-sided top press sealing detection, ensuring the safe and stable operation of the equipment, and reducing the enterprise's operating risks and maintenance costs.
