Description

Technical Field

[0001] This invention relates to the field of centrifuge technology, and in particular to a modular quick-install centrifuge sealing system. Background Technology

[0002] With the development of modern industry towards high efficiency and intelligence, centrifuges are becoming increasingly important in fields such as chemical engineering, pharmaceuticals, bioengineering, and environmental protection. Their operational reliability and ease of maintenance have become key factors affecting production efficiency. However, in existing technologies, centrifuge sealing structures suffer from cumbersome disassembly and assembly procedures, long maintenance cycles, and high skill requirements for operators. At the same time, traditional sealing systems lack real-time status monitoring methods, making it difficult to detect uneven pressure distribution or abnormal attenuation at the sealing interface in a timely manner. This can easily lead to sudden leaks and unplanned equipment shutdowns, thus restricting the overall performance of centrifuges in continuous production scenarios.

[0003] Chinese Patent Publication No. CN111957447A discloses an intelligent centrifuge, comprising the following mechanisms: a material conveying mechanism, using a conveyor frame, conveyor roller group, drive motor, transmission shaft, etc., to realize automatic material feeding and discharging; a lifting and clamping mechanism, including a hydraulic lifting assembly and a clamping assembly, which realizes material lifting and clamping through hydraulic cylinders, lifting plates, upper positioning plates, etc.; a positioning mechanism, divided into upper and lower positioning assemblies, using asymmetrically arranged positioning cylinders and positioning holes to ensure the positional accuracy of the lifting plate and the upper positioning plate during rotation; a protective door system, a front and rear opening protective door, driven by cylinders, which realizes synchronous opening and closing through levers and gear sets, and has both water blocking and safety protection functions; and a PLC controller, which integrates the control of conveying, lifting, positioning, and protective door actions to realize fully automated operation.

[0004] Therefore, it is evident that the existing technology has the following problems:

[0005] This invention does not consider the need for real-time monitoring and early warning of the sealing status of the centrifuge's core sealing mechanism, lacks real-time monitoring of key sealing parameters such as internal pressure and leakage rate, and fails to form a safety protection system for early warning and risk classification of sealing performance degradation, so as to improve the predictive maintenance capability of equipment operation and build a more complete fault defense process, thus causing the equipment safety management to be lagging and passive. Summary of the Invention

[0006] To address this, the present invention provides a modular quick-install centrifuge sealing system to overcome the problems in the prior art that do not consider real-time monitoring of the sealing status of the centrifuge sealing mechanism and lack real-time monitoring of key sealing parameters such as internal pressure and leakage rate, resulting in low monitoring efficiency of the centrifuge sealing system.

[0007] To achieve the above objectives, the present invention provides a modular quick-install centrifuge sealing system, comprising:

[0008] The acquisition module is used to collect characteristic data parameters of the sealing mechanism inside the target centrifuge, as well as environmental characteristic parameters of the target centrifuge;

[0009] A sealing mechanism assembly used to maintain stable internal pressure and prevent leakage of the media inside the centrifuge;

[0010] The analysis module is used to analyze the characteristic data representation value based on the characteristic data parameter information, and to analyze the environmental characteristic representation value based on the environmental characteristic parameters;

[0011] The control module is used to determine whether the centrifuge seal stability meets the standard based on the comparison result between the feature data characterization value and the predetermined feature data characterization threshold.

[0012] If it is determined that the centrifuge seal stability does not meet the standard, the reasons for the centrifuge seal stability not meeting the standard and the corresponding handling strategies are determined based on the environmental characteristic characterization values: the adjustment range of the characteristic data characterization threshold is determined, and an alarm is issued to replace the pressure sensor.

[0013] The characteristic data parameters include pressure value and leakage rate; the environmental characteristic parameters include ambient temperature and centrifuge speed.

[0014] Furthermore, the analysis module is used to determine the feature data representation value based on the sum of the first representation factor and the second representation factor, wherein,

[0015] The first characterization factor is determined based on the ratio of the centrifuge pressure value to a predetermined pressure threshold;

[0016] The second characterization factor is determined based on the ratio of the leakage rate of the medium inside the centrifuge to a predetermined leakage rate threshold.

[0017] Furthermore, the analysis module is used to determine the environmental characteristic characterization value based on the sum of the first environmental factor and the second environmental factor, wherein,

[0018] The first environmental factor is determined based on the ratio of the ambient temperature in the centrifuge area to a predetermined ambient temperature threshold;

[0019] The second environmental factor is determined based on the ratio of centrifuge speed to a predetermined centrifuge speed threshold.

[0020] Furthermore, the control module is used to determine whether the centrifuge seal stability meets the standard based on the comparison result between the feature data characterization value and the predetermined feature data characterization threshold, including:

[0021] If the characteristic data representation value is less than the predetermined first characteristic data representation threshold or the characteristic data representation value is greater than the predetermined second characteristic data representation threshold, then the centrifuge seal stability is determined to be non-compliant with the standard. Based on the environmental characteristic representation value, the reasons for the centrifuge seal stability non-compliant with the standard and the corresponding handling strategy are determined.

[0022] Wherein, the predetermined first feature data representation threshold is less than the predetermined second feature data representation threshold.

[0023] Furthermore, when the centrifuge seal stability fails to meet the standard, the reasons for the failure to meet the standard based on the environmental characteristic characterization values ​​include:

[0024] If the environmental characteristic characterization value is less than the predetermined first environmental characteristic characterization threshold, then the reason why the centrifuge stability does not meet the standard is determined as the first reason label;

[0025] If the environmental characteristic characterization value is greater than the predetermined second environmental characteristic characterization threshold, then the reason why the centrifuge stability does not meet the standard is determined as the second reason label;

[0026] If the environmental characteristic value is greater than a predetermined first environmental characteristic threshold and less than or equal to a predetermined second environmental characteristic threshold, then the reason why the centrifuge stability does not meet the standard is determined to be the third reason label.

[0027] Furthermore, the corresponding handling strategies for the reasons why the centrifuge seal stability does not meet the standard include:

[0028] If the first cause label is selected, then stop feeding to reduce the load;

[0029] If the label indicates the second cause, then issue an alarm to replace the pressure sensor.

[0030] If it is a third cause label, then determine the adjustment range of the feature data representation threshold.

[0031] Furthermore, the adjustment range of the feature data characterization threshold is determined based on the difference between the environmental feature characterization value and a predetermined first environmental feature characterization threshold.

[0032] Furthermore, the control module determines the conditions for issuing an alarm to replace the pressure sensor as follows:

[0033] The feature data representation value is less than a predetermined first feature data representation threshold or the feature data representation value is greater than a predetermined second feature data representation threshold;

[0034] Furthermore, the environmental feature characterization value is greater than the predetermined second environmental feature characterization threshold.

[0035] Furthermore, the acquisition module component includes an integrated pressure sensing unit for real-time monitoring of the pressure value at the sealing interface of the centrifuge sealing mechanism.

[0036] Furthermore, the sealing mechanism assembly also includes a sealing module and a quick-locking mechanism, wherein,

[0037] The sealing module adopts a composite structure of preformed elastomer and rigid skeleton, and its edges are provided with guide positioning grooves;

[0038] The quick-locking mechanism includes a rotary latch and a flexible locking tongue, which achieves axial compression and circumferential fixation between the sealing module and the base through a single rotation.

[0039] Compared with existing technologies, the advantages of this invention are as follows: This invention provides a modular, quick-install centrifuge sealing system. A data acquisition module collects characteristic data parameters from the internal sealing mechanism of the target centrifuge, as well as environmental characteristic parameters of the target centrifuge. A sealing mechanism assembly maintains internal pressure stability and prevents media leakage within the centrifuge. An analysis module analyzes characteristic data representation values ​​based on the aforementioned characteristic data parameters and environmental characteristic parameters. A control module determines whether the centrifuge seal stability meets standards based on a comparison of the characteristic data representation values ​​with a predetermined characteristic data representation threshold, determines the adjustment range of the characteristic data representation threshold, and issues an alarm to replace the pressure sensor. This invention improves the accuracy of the centrifuge sealing system by determining whether the centrifuge seal stability meets standards through characteristic data representation values.

[0040] In particular, this invention achieves multi-dimensional and accurate diagnosis of centrifuge sealing stability by constructing a dual quantitative monitoring system of characteristic data parameters and environmental characteristic parameters. The system can not only determine whether the sealing status is qualified, but also dynamically adjust the judgment threshold according to the environmental conditions, effectively avoiding misjudgment caused by changes in operating conditions and improving the accuracy of the system. At the same time, by analyzing pressure values ​​and leakage rates, the system has the preliminary diagnostic capability for pressure sensor status maintenance, thus improving the reliability of the system.

[0041] In particular, this invention integrates and correlates the collected multi-source data through an analysis module, accurately calculating the core indicators characterizing the health status of the equipment. This allows operators to maintain the equipment not based on guesswork but on accurate data-driven judgment, significantly improving the accuracy and efficiency of diagnosis.

[0042] In particular, this invention enables early diagnosis, accurate identification, and root cause tracing of centrifuge sealing performance through a control module. This transforms maintenance behavior from passive response to proactive intervention and precise planning. The system can clearly distinguish different root causes of failure, such as natural aging of seals, deterioration of external operating conditions, or sensor failure. Maintenance personnel can prepare the correct spare parts in advance and implement targeted maintenance plans, significantly reducing unplanned downtime. This predictive maintenance mode reduces the over-maintenance that may be caused by traditional periodic maintenance and also reduces secondary damage caused by the escalation of faults.

[0043] In particular, this invention accurately identifies the root cause of seal failure through the control module and performs self-diagnosis of the pressure sensor status, effectively avoiding unnecessary replacement of parts and waste of resources due to misjudgment. When the system determines that the problem originates from external working conditions or sensor failure, it can avoid unnecessary replacement of seals without faults, directly saving spare parts costs. At the same time, by maintaining the centrifuge in the optimal sealing state, it reduces product loss and raw material waste caused by material leakage, and reduces the additional energy consumption and environmental costs incurred in handling leaked materials.

[0048] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0049] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0050] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Please see Figure 1 The diagram shown is a structural block diagram of a modular quick-install centrifuge sealing system according to an embodiment of the present invention. The present invention provides a modular quick-install centrifuge sealing system, comprising:

[0052] The acquisition module is used to collect characteristic data parameters of the sealing mechanism inside the target centrifuge, as well as environmental characteristic parameters of the target centrifuge;

[0053] A sealing mechanism assembly used to maintain stable internal pressure and prevent leakage of the media inside the centrifuge;

[0054] The analysis module is used to analyze the characteristic data representation value based on the characteristic data parameter information, and to analyze the environmental characteristic representation value based on the environmental characteristic parameters;

[0055] The control module is used to determine whether the centrifuge seal stability meets the standard based on the comparison result between the feature data characterization value and the predetermined feature data characterization threshold.

[0056] If it is determined that the centrifuge seal stability does not meet the standard, the reasons for the centrifuge seal stability not meeting the standard and the corresponding handling strategies are determined based on the environmental characteristic characterization values: the adjustment range of the characteristic data characterization threshold is determined, and an alarm is issued to replace the pressure sensor.

[0057] The characteristic data parameters include pressure value and leakage rate; the environmental characteristic parameters include ambient temperature and centrifuge speed.

[0058] It is understood that the pressure value in the embodiment is the pressure value of the centrifuge sealing mechanism, and the leakage rate in the embodiment is the ratio of the leakage amount of the medium inside the centrifuge sealing mechanism to the total amount before leakage. Preferably, the medium in the embodiment is gas.

[0059] As is understandable, pressure is a physical quantity that characterizes the force exerted by the process fluid inside a centrifuge on the cavity wall per unit area. It is a key direct parameter for measuring the load and sealing pressure state inside the system, and its commonly used unit is kPa.

[0060] Understandably, leakage rate refers to the volume or mass of medium leaking through the sealing interface per unit time, which is the most critical quantitative indicator. For example, the common unit for gas sealing is Pa·m³ / s or mL / min, and the common unit for liquid sealing is mL / h or g / h. The smaller the value, the better the sealing performance.

[0061] It is understandable that ambient temperature refers to the thermodynamic state of the air surrounding the centrifuge when it is working, and its commonly used unit is ℃.

[0062] It is understandable that centrifuge speed refers to the angular velocity of the centrifuge drum rotating around its central axis, and its common unit is r / min.

[0063] Please see Figure 2 The diagram shows a flowchart of the operation of the modular quick-assembly centrifuge sealing system according to an embodiment of the present invention. The operation steps of the centrifuge sealing system according to the embodiment of the present invention include:

[0064] Step S1: Collect characteristic data parameters of the internal sealing mechanism of the target centrifuge.

[0065] Step S2: Analyze the feature data representation value based on the feature data parameter information;

[0066] Step S3: Determine whether the centrifuge seal stability meets the standard based on the comparison result between the feature data characterization value and the predetermined feature data characterization threshold.

[0067] If the characteristic data representation value is less than or equal to the predetermined characteristic data representation threshold, then the centrifuge seal stability is determined to be non-compliant with the standard.

[0068] If the characteristic data representation value is greater than the predetermined characteristic data representation threshold, then the centrifuge seal stability is determined to meet the standard.

[0069] Step S4: If it is determined that the centrifuge's sealing stability does not meet the standard, then extract the environmental characteristic parameters of the target centrifuge.

[0070] Step S5: Analyze the environmental characteristic characterization values ​​based on the environmental characteristic parameters;

[0071] Step S6: Based on the environmental characteristic characterization values, determine the reasons why the centrifuge seal stability does not meet the standards and the corresponding handling strategies: determine the adjustment range of the characteristic data characterization threshold, and determine to issue an alarm to replace the pressure sensor.

[0072] This invention provides a modular, quick-install centrifuge sealing system. A data acquisition module collects characteristic data parameters from the internal sealing mechanism of the target centrifuge, as well as environmental characteristic parameters of the centrifuge. The sealing mechanism assembly maintains internal pressure stability and prevents media leakage. An analysis module analyzes characteristic data parameters and environmental characteristic parameters to determine whether the centrifuge seal stability meets standards, and determines the adjustment range of the characteristic data threshold, triggering an alarm to replace the pressure sensor. This invention improves the accuracy of the centrifuge sealing system by determining whether the centrifuge seal stability meets standards through characteristic data values.

[0073] Specifically, the analysis module is used to determine the feature data representation value based on the sum of the first representation factor and the second representation factor, wherein,

[0074] The first characterization factor is determined based on the ratio of the centrifuge pressure value to a predetermined pressure threshold;

[0075] The second characterization factor is determined based on the ratio of the leakage rate of the medium inside the centrifuge to a predetermined leakage rate threshold.

[0076] The analysis module described in the embodiment is used to analyze the feature data representation value based on the feature data parameter information, including:

[0077] The ratio of the pressure value to a predetermined pressure threshold is defined as the first characterization factor;

[0078] The ratio of the leakage rate to a predetermined leakage rate threshold is defined as the second characterization factor;

[0079] The sum of the first characterization factor and the second characterization factor is determined as the characteristic data characterization value.

[0080] In this embodiment, the predetermined pressure threshold is pre-set, wherein the average internal pressure of the centrifuge sealing mechanism within one month prior to system operation is determined as the pressure threshold.

[0081] In this embodiment, the predetermined leakage rate threshold is pre-set, wherein the average leakage rate of the medium inside the centrifuge sealing mechanism within one month prior to system operation is determined as the leakage rate threshold.

[0082] In this embodiment of the invention, the pressure value and leakage rate are normalized into a first characterization factor and a second characterization factor respectively through the analysis module, and then linearly superimposed into a single feature data characterization value. This constructs a highly integrated and quantitative sealing condition evaluation index, unifying complex parameters with multiple dimensions and different dimensions into dimensionless standardized ratios. By setting a reasonable fluctuation range, the accuracy of centrifuge sealing performance is accurately judged, improving the accuracy and efficiency of condition detection.

[0083] Specifically, the analysis module is used to determine the environmental characteristic characterization value based on the sum of the first environmental factor and the second environmental factor, wherein,

[0084] The first environmental factor is determined based on the ratio of the ambient temperature in the centrifuge area to a predetermined ambient temperature threshold;

[0085] The second environmental factor is determined based on the ratio of centrifuge speed to a predetermined centrifuge speed threshold.

[0086] The analysis module described in the embodiment is used to analyze environmental characteristic values ​​based on the environmental characteristic parameters, including:

[0087] The ratio of the ambient temperature to a predetermined ambient temperature threshold is defined as the first environmental factor;

[0088] The ratio of the centrifuge speed to a predetermined centrifuge speed threshold is defined as the second environmental factor;

[0089] The sum of the first environmental factor and the second environmental factor is determined as the environmental characteristic characterization value.

[0090] In this embodiment, the predetermined ambient temperature threshold is pre-set, wherein the average ambient temperature of the centrifuge area within one month prior to system operation is determined as the ambient temperature threshold.

[0091] In this embodiment, the predetermined centrifuge speed threshold is pre-set, wherein the average centrifuge speed within one month prior to system operation is determined as the centrifuge speed threshold.

[0092] This invention, through its analysis module, normalizes ambient temperature and centrifuge speed into a first environmental factor and a second environmental factor, and merges them into a single environmental characteristic value. This constructs a comprehensive quantitative evaluation system for external operating conditions. By setting differentiated tolerance ranges for temperature and speed that conform to their physical characteristics, it achieves precise and efficient monitoring of the external operating environment. It can keenly identify equipment failure risks induced by environmental overheating, overcooling, or abnormal speed, improving the pertinence of diagnosis and early warning capabilities. This effectively ensures that the centrifuge always operates within the optimal process window, extends equipment lifespan, and reduces performance degradation and energy waste caused by environmental disturbances.

[0093] Please see Figure 3 As shown, this is a logic diagram used in an embodiment of the present invention to determine whether the centrifuge seal stability meets the standard based on the comparison result of the feature data characterization value and the predetermined feature data characterization threshold. The control module of the present invention is used to determine whether the centrifuge seal stability meets the standard based on the comparison result of the feature data characterization value and the predetermined feature data characterization threshold, including:

[0094] If the characteristic data representation value is less than the predetermined first characteristic data representation threshold or the characteristic data representation value is greater than the predetermined second characteristic data representation threshold, then the centrifuge seal stability is determined to be non-compliant with the standard. Based on the environmental characteristic representation value, the reasons for the centrifuge seal stability non-compliant with the standard and the corresponding handling strategy are determined.

[0095] If the characteristic data representation value is within the range of the predetermined first characteristic data representation threshold and the predetermined second characteristic data representation threshold, then the centrifuge seal stability is determined to meet the standard and the system is operating normally.

[0096] Wherein, the predetermined first feature data representation threshold is less than the predetermined second feature data representation threshold.

[0097] In this embodiment, the predetermined first feature data representation threshold is preset, and preferably, the first feature data representation threshold is 1.55.

[0098] In this embodiment, the predetermined second feature data representation threshold is preset, and preferably, the second feature data representation threshold is 2.0.

[0099] This invention, through a control module that integrates characteristic data of pressure and leakage rate to set a clear acceptable range, and establishes an automated judgment logic based on this range, achieves accurate and efficient diagnosis of centrifuge seal stability. The control module can instantly complete data comparison, and once the characteristic value exceeds the preset threshold, an alarm is immediately triggered, and environmental characteristic data is linked to intelligently analyze the root cause. This transforms fault diagnosis from traditional manual experience-based judgment to intelligent rapid response, which not only greatly improves the accuracy of equipment monitoring and operation and maintenance efficiency, but also effectively prevents material leakage, production interruption, or safety accidents caused by seal failure. While ensuring production continuity and product quality, it significantly reduces operation and maintenance costs and potential environmental risks.

[0100] Specifically, when the centrifuge seal stability fails to meet the standard, the reasons for this failure, determined based on the environmental characteristic values, include:

[0101] If the environmental characteristic characterization value is less than the predetermined first environmental characteristic characterization threshold, then the reason why the centrifuge stability does not meet the standard is determined as the first reason label;

[0102] If the environmental characteristic characterization value is greater than the predetermined second environmental characteristic characterization threshold, then the reason why the centrifuge stability does not meet the standard is determined as the second reason label;

[0103] If the environmental characteristic value is greater than a predetermined first environmental characteristic threshold and less than or equal to a predetermined second environmental characteristic threshold, then the reason why the centrifuge stability does not meet the standard is determined to be the third reason label.

[0104] In the embodiments, the predetermined first environmental feature characterization threshold is preset, and the first environmental feature characterization threshold is preferably 1.9.

[0105] In the embodiments, the predetermined second environmental feature characterization threshold is preset, and the second environmental feature characterization threshold is preferably 2.1.

[0106] Understandably, the first cause label is that the centrifuge is too cold or the speed is insufficient; the second cause label is that the centrifuge is too high or the speed is too fast; and the third cause label is that the seals themselves are aged, worn, or damaged.

[0107] Understandably, excessive cooling of the centrifuge can lead to thickened lubricating oil, frozen coolant, pipe contraction and leakage, or loss of performance of electronic components. Insufficient centrifuge speed can result in poor separation effect, reduced separation rate, and contamination of subsequent processes, mainly affecting the quality of produced products and the lifespan of the equipment.

[0108] It is understandable that overheating of a centrifuge can lead to drum explosions, shaft breakage, and fires. Excessive centrifuge speed can cause solid particles to be compressed too densely and materials such as biological cells to be destroyed in their original separation form, which can lead to catastrophic accidents.

[0109] This invention achieves rapid and accurate diagnosis and graded early warning of the root causes of sealing stability failures by intelligently comparing environmental characteristic values ​​with preset thresholds. The mechanism can clearly distinguish three essentially different causes and automatically trigger matching handling strategies, completely changing the traditional lagging mode that relies on manual investigation. It elevates fault diagnosis from phenomenon description to cause tracing, thereby improving the accuracy and efficiency of operation and maintenance response. The system can not only prioritize the handling of the most dangerous safety risks and effectively prevent catastrophic accidents, but also avoid misjudgment and over-repair by accurately locating the root cause of the problem, significantly saving maintenance costs and time, and ensuring the continuity and stability of production.

[0110] Specifically, the corresponding handling strategies for the reasons why the centrifuge seal stability does not meet the standard include:

[0111] If the first cause label is selected, then stop feeding to reduce the load;

[0112] If it is a second cause label, then determine the adjustment range of the feature data representation threshold;

[0113] If the label indicates a third cause, then an alarm should be issued to replace the pressure sensor.

[0114] If the first cause label is used in the implementation example, then it is determined that feeding should be stopped to reduce the load;

[0115] If the example is a second cause label, then the adjustment range of the feature data characterization threshold is determined;

[0116] If the example is labeled as a third cause, then the system is shut down for maintenance, and an alarm is issued to replace the pressure sensor.

[0117] This invention constructs a hierarchical and precise operation and maintenance decision-making system by intelligently matching differentiated processing strategies to different root causes of faults. It can automatically trigger escalating response measures from inspection and adjustment to emergency shutdown based on diagnostic results, ensuring that limited resources are prioritized for addressing the most pressing safety risks, thereby effectively preventing catastrophic accidents. At the same time, by clearly distinguishing between emergency shutdown and planned maintenance, the system minimizes unnecessary production interruptions while ensuring the safety of personnel and equipment, enabling maintenance activities to proceed in an orderly manner and improving the precision of equipment management and operation and maintenance efficiency.

[0118] Specifically, the adjustment range of the feature data representation threshold is determined based on the difference between the environmental feature representation value and a predetermined first environmental feature representation threshold. The embodiment determines the adjustment range and process of the feature data representation threshold, including:

[0119] Calculate the difference between the environmental feature characterization value and the predetermined first environmental feature characterization threshold;

[0120] If the difference is less than a predetermined difference threshold, the adjustment range of the feature data representation threshold is determined to be selected within the range [0.85, 0.99]. In this embodiment, the preferred adjustment range is 0.95.

[0121] If the difference is greater than a predetermined difference threshold, the adjustment range of the feature data representation threshold is selected within the range [1.05, 1.25]. In this embodiment, the preferred adjustment range is 1.15.

[0122] This invention constructs an adaptive intelligent fault-tolerance and safety enhancement mechanism by dynamically adjusting the characteristic data representation thresholds for different fault modes. When a potential mechanical fault is identified, the evaluation criteria can be temporarily relaxed to avoid false alarms under special conditions such as insufficient system drive force, ensuring the continuity and stability of production operations. When facing emergency safety risks, it automatically switches to a more stringent safety mode threshold, significantly improving the system's sensitivity to abnormal phenomena such as minor leaks, and establishing a higher standard warning line for risk prevention and control. The differentiated threshold management strategy not only effectively reduces unnecessary downtime caused by environmental interference, but also greatly improves the safety margin of equipment operation through early warning at critical moments.

[0123] Please see Figure 4 As shown, this is a logic diagram used in an embodiment of the present invention to determine whether to replace the pressure sensor based on the environmental characteristic values. The conditions under which the control module of the present invention determines to issue an alarm to replace the pressure sensor are:

[0124] The feature data representation value is less than a predetermined first feature data representation threshold or the feature data representation value is greater than a predetermined second feature data representation threshold;

[0125] Furthermore, the environmental feature characterization value is greater than the predetermined second environmental feature characterization threshold.

[0126] Understandably, if the characteristic data characterization value exceeds the acceptable range, it means that the sealing system has failed. If the environmental characteristic characterization value exceeds the second environmental characteristic characterization threshold, it means that the centrifuge is under extreme conditions of high temperature or overspeed. Detecting both of these signals at the same time violates the laws of physics and is highly likely to be an error value given by the pressure sensor signal drift or damage. Therefore, the pressure sensor needs to be replaced.

[0127] This invention establishes a multi-parameter logical association model to achieve intelligent diagnosis and proactive early warning of pressure sensor faults. By identifying the contradictory state of simultaneous sealing system failure and high temperature or overspeed operation, which violates the basic physical laws of centrifugal pumps, it can accurately determine whether the pressure sensor has signal drift or damage and automatically trigger a replacement alarm. This changes the traditional passive mode of relying on periodic calibration or handling only after a fault occurs, and elevates sensor maintenance from preventive to predictive. It effectively reduces misjudgments, misoperations, and unplanned downtime and resource waste caused by sensor inaccuracy, and significantly improves the intelligence level and operation and maintenance efficiency of the entire monitoring system.

[0128] Specifically, the acquisition module component includes a system-integrated pressure sensing unit for real-time monitoring of the pressure value at the centrifuge sealing interface.

[0129] It is understandable that the system pressure sensing unit consists of a pressure sensor array, which scans to obtain the pressure distribution value.

[0130] This invention employs a pressure sensor array to perform real-time scanning and monitoring of the pressure distribution at the sealing interface, achieving a technological leap from single-point measurement to full-field perception. It can accurately capture the microscopic non-uniformity of the sealing pair's contact state, providing unprecedented multi-dimensional spatial information for sealing performance evaluation. The refined monitoring capability can keenly identify early fault characteristics such as local deformation, uneven wear, or slag inclusion on the sealing surface, thereby significantly advancing the fault warning point. This changes the uncertainty of traditionally relying on overall parameters to infer the sealing state. By accurately locating potential hazards, it provides direct data support for predictive maintenance, thereby improving the reliability and safety margin of equipment operation while effectively avoiding material leakage and unplanned downtime caused by sealing failure.

[0131] Specifically, the sealing mechanism assembly further includes a sealing module and a quick-locking mechanism, wherein,

[0132] The sealing module adopts a composite structure of preformed elastomer and rigid skeleton, and its edges are provided with guide positioning grooves;

[0133] The quick-locking mechanism includes a rotary latch and a flexible locking tongue, which achieves axial compression and circumferential fixation between the sealing module and the base through a single rotation.

[0134] It is understandable that elastomers are a class of polymeric materials that deform when subjected to force and can quickly return to their original shape after the external force is removed.

[0135] Understandably, a rigid frame is a rigid component embedded inside a sealing module or serving as its supporting structure.

[0136] This invention achieves efficient maintenance and reliable protection of the sealing structure by employing modular sealing components and a quick-locking mechanism. The design ensures precise forming and long-term stability of the sealing interface through a pre-formed composite structure. The cooperation between the guide positioning groove and the rotating buckle allows for accurate positioning and secure locking without special tools during installation, greatly simplifying the operation process. The integrated design not only significantly shortens the replacement time of the seals and reduces downtime losses due to equipment maintenance, but also effectively improves the consistency of seal assembly quality by eliminating manual installation errors. While reducing maintenance costs and labor intensity, it also reduces the risk of leakage due to improper seal installation, ensuring the continuity of the production process and environmental safety.

[0137] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
