Description

Technical Field

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

[0002] In industrial production, six-sided top presses are core equipment in key processes such as superhard material synthesis and high-pressure scientific research. Their sealing performance is directly related to production safety, product quality, and economic benefits. With the growing demand for superhard materials (such as synthetic diamond and cubic boron nitride) in modern industry, the application of six-sided top presses is becoming increasingly widespread, and the stability and reliability of the equipment are also facing higher requirements.

[0003] Traditional seal inspection methods for six-sided top presses rely on operator experience or a single pressure test. For example, seal performance is assessed by visually inspecting the seal surface for visible damage or simply observing pressure changes over a short period of time after pressurization. These methods have numerous limitations: visual inspections struggle to detect potential defects such as microcracks and wear, making it impossible to quantitatively assess the integrity of the seal surface. A single pressure test cannot accurately reflect the actual performance of the seal structure under prolonged, high-pressure conditions, and is prone to missed detections or misjudgments, resulting in defective equipment operation. Seal failure can not only disrupt production and render the product scrapped, but can also trigger leaks of high-temperature, high-pressure media, and even lead to serious safety hazards such as explosions. Furthermore, as six-sided top presses evolve toward larger and more precise designs, their seal structures are becoming increasingly complex, making traditional inspection methods unable to meet the stringent reliability and safety requirements of modern industrial production.

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

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

[0006] In one aspect, the present invention provides a seal detection method for a six-sided top press, comprising:

[0007] Pre-processing the sealing surface of the six-sided top press, collecting image information of the sealing surface, and preliminarily obtaining an integrity index of the sealing surface based on the image information;

[0008] 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 from the pressure sensor, and perform a preliminary sealing performance score based on the pressure information;

[0009] Keeping the set pressure value unchanged, collecting pressure information at fixed intervals, calculating the pressure change value between the pressure information, and determining whether to revise the preliminary sealing performance score based on the pressure change value;

[0010] If it is determined that the preliminary sealing performance score needs to be adjusted, a correction factor is calculated based on the pressure change value, and the preliminary sealing performance score is corrected based on the correction factor to obtain a final sealing performance score;

[0011] A safety warning is issued to the six-sided top press based on the integrity index and the final value of the sealing performance score.

[0012] Furthermore, the collecting of the image information of the sealing surface and preliminarily obtaining the integrity index of the sealing surface according to the image information includes:

[0013] Extract scratches and wear from the sealing surface image information, calculate the total area of ​​scratches and wear, and record it as the damage area;

[0014] Setting a damage limit threshold, if the damage area is zero, the integrity index is 1;

[0015] If the damage area is greater than zero and the damage area is less than the damage limit threshold, the integrity index is the first index;

[0016] If the damage area is greater than or equal to the damage limit threshold, the integrity index is the second index;

[0017] 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.

[0018] Furthermore, the step 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 includes:

[0019] 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;

[0020] 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;

[0021] The first score is a full score, and the first score is greater than the second score.

[0022] Furthermore, 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:

[0023] Preset a collection time period, and collect pressure information at fixed intervals within the collection time period;

[0024] Using the same pressure sensor as a unit and building a pressure sequence in time sequence;

[0025] The pressure change value of the pressure information in each pressure sequence is calculated to construct a pressure change sequence.

[0026] Furthermore, the determining whether to revise the preliminary sealing performance score according to the pressure change value includes:

[0027] If all parameters in the pressure change sequence are zero, it is determined that the preliminary sealing performance score will not be corrected;

[0028] Otherwise, it is determined that the preliminary sealing performance score needs to be revised.

[0029] 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:

[0030] 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;

[0031] 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;

[0032] 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] Furthermore, the step of correcting the preliminary sealing performance score according to the correction factor to obtain a final sealing performance score includes:

[0034] The final sealing performance score is the product of the preliminary sealing performance score and the correction factor;

[0035] The correction factor has a value range of 1>correction factor>0.

[0036] 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:

[0037] Set sealing performance rating limit values;

[0038] 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;

[0039] 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;

[0040] 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;

[0041] 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;

[0042] The warning levels from low to high are level one warning, level two warning and level three warning.

[0043] Furthermore, the pretreatment of the sealing surface of the six-sided top press includes:

[0044] Disconnect all power connections of the six-sided top press;

[0045] Clean the sealing surface of the six-sided press and remove impurities and foreign matter on the sealing surface.

[0046] Compared with the prior art, the beneficial effect of the present invention is that: in the initial stage of detection, the present invention pre-processes the sealing surface and collects images to obtain the integrity index, which can visually detect physical damage such as scratches and wear on the sealing surface before the equipment is put into operation, identify potential risks in a timely manner, avoid subsequent detection misjudgments or equipment operation failures due to sealing surface defects, and reduce maintenance costs and safety hazards. In the pressure detection link, the basic condition of the seal is quickly judged by the preliminary sealing 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 maintenance process, so that the final sealing performance score value more accurately reflects the sealing performance, and greatly improves the reliability of the test results compared to a single detection method. Finally, a safety warning is issued based on the comprehensive integrity index and the sealing performance score final value, and a multi-dimensional evaluation system is constructed. It can divide the warning level according to different combination situations, provide operators with clear and targeted risk warnings, and enable them to take maintenance or emergency measures in a timely manner, ensure the safe and stable operation of the six-sided top press, improve production efficiency and product quality, and is of great significance to the safe management and efficient operation of industrial production.

[0047] On the other hand, the present application also provides a seal detection system for a six-sided top press, comprising:

[0048] an integrity evaluation module configured to pre-process 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 based on the image information;

[0049] The sealing performance preliminary analysis module is 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 from the pressure sensor, and perform a preliminary sealing performance score based on the pressure information;

[0050] a sealing performance correction module configured to maintain a set pressure value unchanged, collect pressure information at fixed intervals, calculate a pressure change value between the pressure information, and determine whether to correct the preliminary sealing performance score based on the pressure change value;

[0051] 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 based on the pressure change value, and correct the preliminary sealing performance score based on the correction factor to obtain a final sealing performance score;

[0052] The early warning module is configured to provide a safety early warning to the six-sided top press according to the integrity index and the final value of the sealing performance score.

[0053] It is understandable that the sealing detection method and system for the six-sided top press provided in this application have the same beneficial effects and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying 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 to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present disclosure 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 accompanying drawings and in conjunction with the embodiments.

[0058] In some embodiments of the present application, see Figure 1 As shown, this embodiment provides a seal detection method for a six-sided top press, comprising the following steps:

[0059] S100, pre-processing the sealing surface of the six-sided top press, collecting image information of the sealing surface, and preliminarily obtaining an integrity index of the sealing surface based on the image information;

[0060] S200, 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;

[0061] S300, maintaining a set pressure value unchanged, collecting pressure information at fixed intervals, calculating a pressure change value between the pressure information, and determining whether to revise the preliminary sealing performance score based on the pressure change value;

[0062] S400: If it is determined that the preliminary sealing performance score needs to be adjusted, a correction factor is calculated according to the pressure change value, and the preliminary sealing performance score is corrected according to the correction factor to obtain a final sealing performance score;

[0063] S500: issuing a safety warning to the six-sided top press according to the integrity index and the final value of the sealing performance score.

[0064] It is understandable that the present invention, in the initial stage of detection, can visually detect physical damage such as scratches and wear on the sealing surface by pre-processing the sealing surface and collecting images to obtain the integrity index before the equipment is put into operation, identify potential risks in a timely manner, avoid subsequent detection misjudgments or equipment operation failures due to sealing surface defects, and reduce maintenance costs and safety hazards. In the pressure detection link, the basic condition of the seal is quickly judged by the preliminary sealing 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 maintenance process, so that the final sealing performance score value more accurately reflects the sealing performance, greatly improving the reliability of the test results compared to a single detection method. Finally, a safety warning is issued based on the comprehensive integrity index and the sealing performance score final value, and a multi-dimensional evaluation system is constructed. It can divide the warning level according to different combination situations, provide operators with clear and targeted risk warnings, and enable them to take maintenance or emergency measures in a timely manner to ensure the safe and stable operation of the six-sided top press, improve production efficiency and product quality, and have important significance for the safe management and efficient operation of industrial production. Specifically, the sealing surface includes the connection between the pressure cylinder and the pressure head, the contact area between the periphery of the synthetic cavity and each top hammer, and the pipeline interface.

[0065] In some embodiments of the present application, the collecting of image information of the sealing surface and preliminarily obtaining an integrity index of the sealing surface based on the image information includes:

[0066] Extract scratches and wear from the sealing surface image information, calculate the total area of ​​scratches and wear, and record it as the damage area;

[0067] Setting a damage limit threshold, if the damage area is zero, the integrity index is 1;

[0068] If the damage area is greater than zero and the damage area is less than the damage limit threshold, the integrity index is the first index;

[0069] If the damage area is greater than or equal to the damage limit threshold, the integrity index is the second index;

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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:

[0074] 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;

[0075] 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;

[0076] The first score is a full score, and the first score is greater than the second score.

[0077] 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.

[0078] 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.

[0079] 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:

[0080] Preset a collection time period, and collect pressure information at fixed intervals within the collection time period;

[0081] Using the same pressure sensor as a unit and building a pressure sequence in time sequence;

[0082] The pressure change value of the pressure information in each pressure sequence is calculated to construct a pressure change sequence.

[0083] In some embodiments of the present application, determining whether to revise the preliminary sealing performance score according to the pressure change value includes:

[0084] If all parameters in the pressure change sequence are zero, it is determined that the preliminary sealing performance score will not be corrected;

[0085] Otherwise, it is determined that the preliminary sealing performance score needs to be revised.

[0086] 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.

[0087] 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.

[0088] 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:

[0089] 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;

[0090] 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;

[0091] 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.

[0092] 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:

[0093] The final sealing performance score is the product of the preliminary sealing performance score and the correction factor;

[0094] The correction factor has a value range of 1>correction factor>0.

[0095] As can be understood, by taking the total number of pressure changes greater than zero in the pressure variation sequence and comparing it with a set threshold, a preliminary assessment of the frequency of pressure changes can be made. A low total number of changes indicates relatively minor pressure fluctuations and relatively stable sealing performance. In this case, the first correction factor will make a smaller adjustment to the initial score. Conversely, a high total number of changes indicates frequent pressure fluctuations and potential significant sealing performance risks. The second correction factor will make a larger adjustment to the initial score. Furthermore, the relationship between the maximum pressure change and the threshold has been considered to further refine the correction factor adjustment. When the maximum change is small, the initial correction factor value remains unchanged, maintaining a relatively stable score. When the maximum change is large, the threshold is adjusted using an adjustment factor to achieve a final correction factor value that better reflects the actual sealing status of the device. This approach comprehensively considers multiple dimensions of pressure variation, avoiding the biased nature of single-factor judgments. This makes the score correction more scientific and reasonable, helps promptly identify potential sealing performance issues, and provides a strong guarantee for the safe operation of the device.

[0096] Specifically, the collection time is set to 60 minutes, and pressure information is collected every 10 minutes, resulting in a total of 6 pressure change sequences. Among them, the total number of pressure change values ​​greater than zero is 8 times, and the set number threshold is 5 times. Since the total number of changes is greater than the number threshold, the initial value of the correction factor is determined to be the second correction factor. Among these pressure change values, the maximum change is 0.8MPa, and the set change threshold is 0.5MPa. Because the maximum change is greater than the change threshold, the change threshold is adjusted by adjusting the coefficient 0.6, and the final value of the correction factor is the second correction factor multiplied by 0.6. Assuming the preliminary sealing performance score is 80 points, the final 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 company can more accurately evaluate the sealing performance of the six-sided top press, promptly discover and deal with potential sealing problems, and ensure the safety and stability of the production process.

[0097] In some embodiments of the present application, the step of providing a safety warning to the six-sided top press according to the integrity index and the final sealing performance score includes:

[0098] Set sealing performance rating limit values;

[0099] 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;

[0100] 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;

[0101] 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;

[0102] 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;

[0103] The warning levels from low to high are level one warning, level two warning and level three warning.

[0104] 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.

[0105] 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.

[0106] In some embodiments of the present application, the pre-treatment of the sealing surface of the six-sided top press includes:

[0107] Disconnect all power connections of the six-sided top press;

[0108] Clean the sealing surface of the six-sided press and remove impurities and foreign matter on the sealing surface.

[0109] It is understandable that disconnecting all power connections can fundamentally eliminate the risk of electric shock to operators during the inspection process, while also preventing electromagnetic interference to the inspection equipment caused by live operations, thereby ensuring the accuracy of data acquired by inspection instruments such as image acquisition equipment. Cleaning the sealing surface and removing surface impurities and foreign matter can, on the one hand, prevent impurities from affecting the image acquisition effect, prevent misjudgment of defects such as scratches and wear on the sealing surface due to interference from impurities, and ensure the reliability of integrity index calculations. On the other hand, the presence of impurities may damage the flatness of the sealing surface, interfere with the pressure distribution, and cause abnormal data during pressure testing. Cleaning the sealing surface can enable the pressure sensor to more realistically reflect the sealing performance, avoid false detection and missed detection caused by impurities, lay a solid foundation for subsequent sealing performance evaluation based on image analysis and pressure testing, and effectively improve the scientific nature and effectiveness of the entire sealing detection process.

[0110] On the other hand, see Figure 2 As shown, the present application also provides a six-sided top press seal detection system for applying the above-mentioned six-sided top press seal detection method, comprising:

[0111] an integrity evaluation module configured to pre-process 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 based on the image information;

[0112] The sealing performance preliminary analysis module is 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 from the pressure sensor, and perform a preliminary sealing performance score based on the pressure information;

[0113] a sealing performance correction module configured to maintain a set pressure value unchanged, collect pressure information at fixed intervals, calculate a pressure change value between the pressure information, and determine whether to correct the preliminary sealing performance score based on the pressure change value;

[0114] 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 based on the pressure change value, and correct the preliminary sealing performance score based on the correction factor to obtain a final sealing performance score;

[0115] The early warning module is configured to provide a safety early warning to the six-sided top press according to the integrity index and the final value of the sealing performance score.

[0116] 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.
