Description

Technical Field

[0001] The present invention relates to the technical field of equipment life prediction, and in particular to a rubber seal life evaluation method, device, equipment and storage medium. Background Art

[0002] In modern industrial production, rubber seals are widely used as key components in various precision instruments, mechanical equipment and pipeline systems. They play a vital role in ensuring the sealing safety of the system, preventing the exchange of internal and external media, and the safe and stable operation of the equipment. For example, in batteries, rubber seals are often used to seal the battery injection holes. However, during long-term service, especially in harsh environments such as high temperature and high humidity, the physical and mechanical properties and chemical stability of rubber materials will significantly decrease, resulting in weakened sealing performance or even failure, which seriously affects the safety and reliability of equipment and production.

[0003] Traditional rubber seal life evaluation methods mostly focus on the impact of a single environmental factor, such as simply considering the effect of temperature or humidity on rubber aging, ignoring the complexity of the combined effect of temperature and humidity under actual use conditions. This evaluation method often leads to a large deviation between the predicted results and the actual situation, and cannot accurately reflect the actual service life of seals in complex environments, and provide accurate and effective information for equipment maintenance and component replacement plans. Summary of the invention

[0004] In view of this, the present invention provides a rubber seal life evaluation method, device, equipment and storage medium to solve the problem that traditional rubber seal life evaluation methods mostly focus on the influence of a single environmental factor, ignore the complexity of the combined effects of temperature and humidity under actual use conditions, resulting in a large deviation between the predicted results and the actual situation, and cannot accurately reflect the actual service life of the seal in a complex environment, thus providing accurate and effective information for equipment maintenance and component replacement plans.

[0005] In a first aspect, the present invention provides a method for evaluating the life of a rubber seal, the method comprising:

[0006] Obtain aging loss parameters of the rubber seal to be evaluated and a test environment data set of the rubber seal to be evaluated under accelerated aging test conditions; obtain an actual use environment data set of the rubber seal to be evaluated based on the aging loss parameters; calculate an aging acceleration factor of the rubber seal to be evaluated based on the actual use environment data set and the test environment data set; evaluate the life of the rubber seal to be evaluated within a preset future service time based on the aging loss parameters and the aging acceleration factor, and obtain a life evaluation result.

[0007] The rubber seal life evaluation method provided by the present invention can calculate the corresponding aging acceleration factor by combining the actual use environment data set reflecting the rubber seal to be evaluated and the test environment data set of the rubber seal to be evaluated under the accelerated aging test conditions, and can scientifically reflect the correlation between the accelerated test environment and the actual use environment on the aging of the rubber seal. Further, the life of the rubber seal within the preset future service time is evaluated in combination with the calculated aging loss parameters and the aging acceleration factor, so that the evaluation results can be more consistent with the aging behavior of the rubber seal in the complex and changeable actual application environment, and the accuracy of the evaluation is improved. This is conducive to formulating a more reasonable maintenance and replacement plan, avoiding the waste of resources caused by excessive maintenance or equipment failure caused by untimely maintenance, and effectively controlling the operating cost. Therefore, by implementing the present invention, a more accurate and reliable basis is provided for the design, selection and maintenance strategy of rubber seals, ensuring the long-term stable operation of the equipment and reducing the economic losses and safety accidents caused by sealing failure.

[0008] In an optional embodiment, obtaining an actual use environment data set of the rubber seal to be evaluated based on the aging loss parameter includes:

[0009] Obtain parameter types of aging loss parameters; determine environmental parameter sets based on the parameter types; and obtain actual use environment data sets of the rubber seal to be evaluated based on the environmental parameter sets.

[0010] The rubber seal life evaluation method provided by the present invention determines the environmental parameter set by the parameter type of the aging loss parameter, so that the determined environmental parameter set is more in line with the actual influencing factors involved in the aging of the rubber seal, avoiding the blind selection of environmental parameters. Furthermore, the actual use environment data set of the rubber seal to be evaluated is obtained in combination with the environmental parameter set, so that the various environmental conditions of the rubber seal in the specific use scenario can be truly and comprehensively understood.

[0011] In an optional embodiment, based on the aging loss parameter and the aging acceleration factor, the life of the rubber seal to be evaluated within a preset future service time is evaluated to obtain a life evaluation result, including:

[0013] The rubber seal life evaluation method provided by the present invention can determine the life evaluation result by comparing the aging remaining life and the preset future service time.

[0014] In an optional embodiment, the aging remaining life of the rubber seal to be evaluated is calculated based on the aging loss parameter and the aging acceleration factor, including:

[0015] The aging time of the rubber seal to be evaluated is calculated based on the aging loss parameter and the aging acceleration factor; the aging remaining life of the rubber seal to be evaluated is calculated based on the aging time and the preset design service life.

Furthermore, based on the accurately calculated aging time, the aging remaining life of the rubber seal to be evaluated is further calculated, which can intuitively present how long the rubber seal can be used normally, and provide very critical life reference information for users, maintainers and other relevant personnel.

[0017] In an optional implementation, determining a life evaluation result based on the aging remaining life and the preset future service time includes:

[0018] The remaining life due to aging is compared with the preset future service time; if the remaining life due to aging is greater than the preset future service time, the life evaluation result is determined to be that the rubber seal to be evaluated will not age within the preset future service time; if the remaining life due to aging is less than the preset future service time, the actual use environment data set corresponding to the preset future service time is adjusted, and the step of calculating the aging loss parameters is returned, and the evaluation is iterated repeatedly until the rubber seal to be evaluated will not age and fail within the preset future service time, and the life evaluation result is obtained.

[0019] The rubber seal life evaluation method provided by the present invention compares the remaining life after aging with the preset future service time. If the remaining life after aging is less than the preset future service time, the actual use environment data set corresponding to the preset future service time can be adjusted to perform repeated iterative evaluation until the life evaluation of the rubber seal to be evaluated is completed when the rubber seal to be evaluated will not age and fail within the preset future service time. Thus, the use environment of the rubber seal can be set according to the adjusted actual use environment data set so that the rubber seal can reach the preset future service time. Therefore, by implementing the present invention, it is helpful to formulate a more reasonable maintenance plan, avoid waste of resources caused by excessive maintenance, or equipment failure and safety accidents caused by untimely maintenance, and effectively control operating costs.

[0020] In an optional implementation, after comparing the aging remaining life with the preset future service time, the method further includes:

[0021] If the aging remaining life is less than the preset future service time, the preset future service time is adjusted until the aging remaining life is less than the adjusted preset future service time, and the life evaluation result is obtained.

[0022] The rubber seal life evaluation method provided by the present invention can obtain the actual future service time by adjusting the preset future service time if the remaining life due to aging is less than the preset future service time, and replace the rubber seal at the actual future service time. Therefore, by implementing the present invention, it is helpful to formulate a more reasonable replacement plan, avoid equipment failures caused by untimely maintenance, and effectively control operating costs.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] An embodiment of the present invention provides a method for evaluating the life of a rubber seal. By combining a data set reflecting the actual use environment of the rubber seal to be evaluated and a data set of the test environment of the rubber seal to be evaluated under accelerated aging test conditions, a corresponding aging acceleration factor can be calculated, and the life of the rubber seal within a preset future service time can be evaluated in combination with the calculated aging loss parameter and the aging acceleration factor, so as to achieve the effect of improving the accuracy of the rubber seal life evaluation.

[0036] According to an embodiment of the present invention, an embodiment of a method for evaluating the life of a rubber seal is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] In this embodiment, a rubber seal life evaluation method is provided, which can be used in electronic devices such as computers, mobile phones, tablet computers, etc. Figure 1 : is a flow chart of a method for evaluating the life of a rubber seal according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0038] Step S101, obtaining aging loss parameters of the rubber seal to be evaluated and a test environment data set of the rubber seal to be evaluated under accelerated aging test conditions.

[0039] Specifically, rubber seals are in a pressure-bearing state when working. Therefore, the compression permanent deformation rate or stress relaxation rate can be selected as the aging damage parameter, which can reflect the aging degree of the rubber seal to be evaluated under the influence of various factors.

[0040] The compression set rate can be calculated using the following relationship (1):

[0041]

[0042] Wherein: ξ represents the compression permanent deformation rate (%); h0 represents the initial thickness of the rubber seal to be evaluated (mm); h1 represents the limiter height (mm); h2 represents the thickness of the rubber seal to be evaluated after recovery after compression (mm).

[0043] Furthermore, the stress relaxation rate can be calculated using the following relationship (2):

[0044]

[0045] Where: ε represents the stress load loss rate (%); σ0 represents the initial applied stress load (MPa); σ1 represents the stress load at the detection time point (MPa).

[0046] Correspondingly, when the compression permanent deformation rate or stress relaxation rate is selected as the aging damage parameter, the test environment data set may include the humidity value R1 and the temperature value T1 under the test conditions. When other performance parameters are selected as aging loss parameters, the corresponding test environment data set is determined according to the specific performance parameter type.

[0047] Step S102: obtaining a data set of actual use environment of the rubber seal to be evaluated based on the aging loss parameter.

[0048] The actual use environment data set may include a humidity value R0 and a temperature value T0 under actual use conditions.

[0049] Specifically, the actual use environment data set of the rubber seal to be evaluated can be determined in combination with the aging loss parameter.

[0050] In an optional implementation, it can be determined in the following manner:

[0051] Specifically, the humidity value R0 and temperature value T0 under actual use conditions can be obtained by collecting or consulting relevant information. Among them, corresponding environmental monitoring equipment, such as temperature sensors, humidity sensors, etc., can be installed at the actual use site of the rubber seal to be evaluated to collect and record the environmental parameters of the rubber seal in real time. In addition, the aging loss parameter can reflect the aging degree of the rubber seal to be evaluated under the influence of various factors, so by analyzing its numerical value, change trend, etc., it is also possible to preliminarily infer the approximate environmental condition range that the rubber seal may be in during actual use, thereby forming an actual use environment data set containing information such as temperature values ​​and humidity values.

[0052] Step S103, calculating the aging acceleration factor of the rubber seal to be evaluated based on the actual use environment data set and the test environment data set.

[0053] Among them, the aging acceleration factor is used to reflect the accelerated effect of specific environmental conditions (such as high temperature and high humidity) on the aging of the rubber seal to be evaluated.

[0054] Specifically, based on the test environment data set, combined with the actual use environment data set, the aging acceleration factor of the rubber seal to be evaluated under the experimental environment or simulation conditions can be calculated, as shown in the following relationship (3):

[0055]

[0056] Where: k T represents the aging acceleration factor; A represents the pre-exponential factor; b represents the fitting parameter; R1 represents the humidity value under the test conditions (accelerated state); R0 represents the humidity value under the actual use conditions (non-accelerated state); E represents the activation energy, also known as the activation energy; K represents the Boltzmann constant; T0 represents the temperature value under the actual use conditions (non-accelerated state); T1 represents the temperature value under the test conditions (accelerated state).

[0057] Step S104, based on the aging loss parameter and the aging acceleration factor, the life of the rubber seal to be evaluated within a preset future service time is evaluated to obtain a life evaluation result.

[0058] Specifically, by combining the numerical value of the aging degree of the rubber seal to be evaluated under the influence of various factors and the aging acceleration factor that reflects the accelerated effect of specific environmental conditions (such as high temperature and high humidity, etc.) on the aging of the rubber seal to be evaluated, it is possible to evaluate whether the rubber seal to be evaluated will age within the preset future service time and obtain the corresponding life evaluation result.

[0059] The rubber seal life evaluation method provided in this embodiment can calculate the corresponding aging acceleration factor by combining the actual use environment data set reflecting the rubber seal to be evaluated and the test environment data set of the rubber seal to be evaluated under the accelerated aging test conditions, and can scientifically reflect the correlation between the accelerated test environment and the actual use environment on the aging of the rubber seal. Further, the life of the rubber seal within the preset future service time is evaluated in combination with the calculated aging loss parameters and the aging acceleration factor, so that the evaluation results can be more consistent with the aging behavior of the rubber seal in the complex and changeable actual application environment, and the accuracy of the evaluation is improved. This is conducive to formulating a more reasonable maintenance and replacement plan, avoiding the waste of resources caused by excessive maintenance or equipment failure caused by untimely maintenance, and effectively controlling the operating cost. Therefore, by implementing the present invention, a more accurate and reliable basis is provided for the design, selection and maintenance strategy of rubber seals, ensuring the long-term stable operation of the equipment and reducing the economic losses and safety accidents caused by sealing failure.

[0060] In this embodiment, a rubber seal life evaluation method is provided, which can be used in electronic devices such as computers, mobile phones, tablet computers, etc. Figure 2 : is a flow chart of a method for evaluating the life of a rubber seal according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0061] Step S201, obtaining the aging loss parameters of the rubber seal to be evaluated and the test environment data set of the rubber seal to be evaluated under the accelerated aging test conditions. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0062] Step S202: obtaining a data set of actual use environment of the rubber seal to be evaluated based on the aging loss parameter.

[0063] Specifically, the above step S202 includes:

[0064] Step S2021, obtaining the parameter type of the aging loss parameter.

[0065] Specifically, according to the description of step S101 above, the aging loss parameter may be one of a compression set rate and a stress relaxation rate.

[0066] Among them, the compression permanent deformation rate reflects the change in the shape retention ability of the rubber seal after a certain period of time under pressure bearing and other environmental factors. Therefore, its parameter type belongs to a type of parameter that is related to the physical deformation of the rubber seal and is affected by the external environment.

[0067] Furthermore, the stress relaxation rate reflects the relaxation of the internal stress of the rubber seal due to changes in time and external environment. Therefore, its parameter type may be a parameter type related to the change in the internal stress of the rubber seal and associated with the effect of the external environment.

[0068] Step S2022, determining an environmental parameter set based on the parameter type.

[0069] Specifically, when the aging loss parameter type is related to physical deformation (such as compression permanent deformation rate): since the physical deformation of rubber seals is greatly affected by environmental factors such as temperature and humidity, the corresponding environmental parameter set should include temperature and humidity related parameters.

[0070] Furthermore, changes in temperature will affect the thermal motion of rubber molecules. High temperature may make the rubber softer and more prone to deformation, while low temperature may make it hard and brittle, thereby affecting the compression permanent set rate; humidity will change the water content of the rubber, affecting its flexibility and other properties, and indirectly affecting physical deformation.

[0071] Furthermore, when the aging loss parameter type is related to the change of internal stress (such as the stress relaxation rate): temperature is the key influencing factor. The increase in temperature will accelerate the movement of the rubber molecular chain and promote faster stress relaxation, while the decrease in temperature has the opposite effect. Humidity will affect the cross-linking structure of the rubber, etc., and affect the internal stress transfer and relaxation process. Therefore, the corresponding environmental parameter set must cover temperature and humidity.

[0072] Step S2023, obtaining an actual use environment data set of the rubber seal to be evaluated based on the environmental parameter set.

[0073] Specifically, data of each parameter in the determined environmental parameter set may be collected. Further, the collected data on each environmental parameter is sorted to form an actual use environment data set of the rubber seal to be evaluated, which includes the humidity value R0 and the temperature value T0 under actual use conditions.

[0074] Step S203, based on the actual use environment data set and the test environment data set, calculate the aging acceleration factor of the rubber seal to be evaluated. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0075] Step S204: Based on the aging loss parameter and the aging acceleration factor, the life of the rubber seal to be evaluated within the preset future service time is evaluated to obtain a life evaluation result. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0076] The rubber seal life evaluation method provided in this embodiment determines the environmental parameter set by the parameter type of the aging loss parameter, so that the determined environmental parameter set is more in line with the actual influencing factors involved in the aging of the rubber seal, avoiding the blind selection of environmental parameters. Furthermore, the actual use environment data set of the rubber seal to be evaluated is obtained in combination with the environmental parameter set, so that the various environmental conditions of the rubber seal in the specific use scenario can be truly and comprehensively understood.

[0077] In this embodiment, a rubber seal life evaluation method is provided, which can be used in electronic devices such as computers, mobile phones, tablet computers, etc. Figure 3 : is a flow chart of a method for evaluating the life of a rubber seal according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0078] Step S301, obtaining the aging loss parameters of the rubber seal to be evaluated and the test environment data set of the rubber seal to be evaluated under the accelerated aging test conditions. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0079] Step S302, based on the aging loss parameter, obtain the actual use environment data set of the rubber seal to be evaluated. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0080] Step S303, based on the actual use environment data set and the test environment data set, calculate the aging acceleration factor of the rubber seal to be evaluated. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0081] Step S304, based on the aging loss parameter and the aging acceleration factor, the life of the rubber seal to be evaluated within a preset future service time is evaluated to obtain a life evaluation result.

[0082] Specifically, the above step S304 includes:

[0083] Step S3041, calculating the aging remaining life of the rubber seal to be evaluated based on the aging loss parameter and the aging acceleration factor.

[0084] In some optional implementations, the above step S3041 includes:

[0085] Step a1, calculating the aging time of the rubber seal to be evaluated based on the aging loss parameter and the aging acceleration factor.

[0086] Step a2, calculating the aging remaining life of the rubber seal to be evaluated based on the aging time and the preset design service life.

[0087] The design service life is artificially set before the rubber seal to be evaluated is designed. Specifically, for the calculation of the aging time, a suitable aging model can be established according to the material properties and aging mechanism of the rubber seal to be evaluated. Common aging models include the Arrhenius equation, the time-temperature superposition principle, etc. Exemplarily, an aging model that satisfies the Arrhenius equation can be constructed to calculate the aging time of the rubber seal to be evaluated using the following relationship (4):

[0088] 1-η=B·exp(-k T ·t a ) (4)

[0089] Where: η represents the aging loss parameter; B represents the test constant; t represents the aging time (h); a represents the time index, and 0 <a<1;k T Represents the aging acceleration factor.

[0090] Furthermore, the aging time may be subtracted from the preset design service life to obtain the aging remaining life of the rubber seal to be evaluated.

[0091] Step S3042, determining the life evaluation result based on the aging remaining life and the preset future service time.

[0092] Specifically, by comparing the aging remaining life and the preset future service time, it can be further determined whether the rubber seal to be evaluated will age within the preset future service time and complete the life evaluation of the rubber seal to be evaluated.

[0093] In some optional implementations, the above step S3042 includes:

[0094] Step b1, comparing the remaining aging life with the preset future service time.

[0095] Step b2: if the remaining life after aging is greater than the preset future service time, the life evaluation result is determined to be that the rubber seal to be evaluated will not age within the preset future service time.

[0096] Step b3, if the remaining life after aging is less than the preset future service time, adjust the actual use environment data set corresponding to the preset future service time, return to the step of calculating the aging loss parameter, and repeatedly iterate the evaluation until the rubber seal to be evaluated will not age within the preset future service time, and obtain the life evaluation result.

[0097] Specifically, the aging remaining life is compared with the preset future service time. If the aging remaining life is greater than the preset future service time, it means that the rubber seal to be evaluated will not age within the preset future service time.

[0098] Furthermore, if the remaining life after aging is less than the preset future service time, it means that the rubber seal to be evaluated may age within the preset future service time. At this time, the actual usage environment data set corresponding to the preset future service time can be adjusted and the evaluation can be recalculated and performed again until the rubber seal to be evaluated will not age within the preset future service time, and the evaluation is completed and the corresponding life evaluation result is obtained.

[0099] Further, in some optional implementations, the above step S3042 further includes:

[0100] Step b4, if the aging remaining life is less than the preset future service time, adjust the preset future service time until the aging remaining life is less than the adjusted preset future service time, and obtain the life evaluation result.

[0101] Specifically, if the remaining life after aging is less than the preset future service time, it means that the rubber seal to be evaluated may age within the preset future service time. At this time, the preset future service time can be shortened so that the rubber seal to be evaluated will not age within the preset future service time.

[0102] The rubber seal life evaluation method provided in this embodiment calculates the aging time of the rubber seal to be evaluated by combining the aging loss parameter and the aging acceleration factor, thereby realizing the quantitative analysis of the aging process of the rubber seal. Further, based on the accurately calculated aging time, the aging remaining life of the rubber seal to be evaluated is further calculated, which can intuitively present how long the rubber seal can be used normally, and provide very critical life reference information for users, maintainers and other relevant personnel. Further, the aging remaining life is compared with the preset future service time. If the aging remaining life is less than the preset future service time, the actual use environment data set corresponding to the preset future service time can be adjusted to perform repeated iterative evaluation until the rubber seal to be evaluated will not age within the preset future service time. The life evaluation of the rubber seal to be evaluated is completed, so that the use environment of the rubber seal can be set according to the adjusted actual use environment data set so that the rubber seal can reach the preset future service time, which is helpful to formulate a more reasonable maintenance plan, avoid the waste of resources caused by excessive maintenance, and effectively control the operating cost. Furthermore, if the remaining life due to aging is less than the preset future service time, the actual future service time can be obtained by adjusting the preset future service time, and the rubber seal can be replaced at the actual future service time, which helps to formulate a more reasonable replacement plan, avoid equipment failures caused by untimely maintenance, and effectively control operating costs.
