Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material environmental test, in particular to a material corrosion failure test method and device simulating industrial dust environment. BACKGROUND

[0002] In the process of industrial production, material corrosion failure is a common problem. Especially in the industrial environment where there are a large number of particulate matters and pollutants in the air, the material aging and failure are obviously affected by pollutants and impacted by particulate matters, which leads to micro-deformation on the surface of the material, thus forming a corrosion weak point. After the corrosion aging starts at this point, it rapidly expands and deepens, thus leading to material failure, which seriously affects the working performance of the equipment and shortens the service life of the equipment. Therefore, developing an accelerated test device and method that can simulate industrial environment and establishing an equivalent relationship between the accelerated test and outdoor empirical test has guiding significance for the reliability prediction of electrical equipment.

[0003] Single-factor environmental simulation accelerated test technology is widely used due to its simple operation and low cost, such as salt spray test, light aging test, and wet heat test. However, the main drawback of these technologies is poor acceleration and correlation, which cannot fully simulate the complex corrosion process that materials face in the actual environment. For example, salt spray test mainly simulates corrosion in salt-containing environments, but ignores the comprehensive influence of other environmental factors such as temperature, humidity, and pollutants on material corrosion. In addition, light aging test mainly focuses on the influence of light on materials, while wet heat test mainly simulates high-temperature and high-humidity environments. These single-factor tests cannot reproduce the multi-factor interaction that materials experience in actual applications.

[0004] With the deepening understanding of the corrosion mechanism of materials, multi-factor environmental simulation accelerated test technology has emerged and rapidly developed in the past decade. These technologies attempt to improve the acceleration and correlation of tests by integrating multiple environmental factors, such as improved salt spray test and cyclic corrosion test. However, existing multi-factor environmental simulation accelerated test technology still has significant problems. On the one hand, most of these test devices are based on salt spray tests with additional influencing factors, and they lack consideration of solid particulate matters, which cannot fully simulate the influence of industrial dust and other solid particulate matters on material corrosion. On the other hand, the synergistic accelerated test for dust particles does not form an equivalent relationship with outdoor empirical tests, which makes it difficult to achieve the required accuracy of electrical equipment life assessment in actual applications.

[0036] The preferred embodiments of the present application are described below in combination with the drawings, and it should be understood that the preferred embodiments described here are only for the purpose of description and explanation of the present application, and are not intended to limit the present application.

[0037] As shown in Figure 2 A material corrosion failure test method under simulated industrial dust environment of the present application comprises the following steps:

[0038] S100, collecting data through the temperature and humidity sensor, the light intensity sensor, the wind speed sensor and the particulate matter concentration sensor arranged at the outdoor characteristic environment point, the collected data including temperature data, humidity data, first light intensity data, first wind speed data and particulate matter concentration data.

[0039] S200, drawing parameter-time curve data according to the collected data, the parameter-time curve data including temperature-time curve, humidity-time curve, light intensity-time curve, wind speed-time curve and particulate matter concentration-time curve.

[0040] S300, performing acceleration rate operation on the temperature data, the humidity data, the light intensity data, the wind speed data and the particulate matter concentration data according to the parameter-time curve data.

[0041] Specifically, S310, the time axis in the parameter-time curve data is proportionally reduced.

[0042] Preferably, in step S310, the time axis in the parameter-time curve data is proportionally reduced by 6-12 times.

[0043] Specifically, S320, each value in the temperature data, humidity data, light intensity data, wind speed data and particulate matter concentration data in the parameter-time curve data is respectively amplified to 2 times, 3 times and 4 times of the original value.

[0044] S400, according to the result of the acceleration rate operation, parameter-time acceleration curve data is drawn, including temperature-time acceleration curve, humidity-time acceleration curve, light intensity-time acceleration curve, wind speed-time acceleration curve and particulate matter concentration-time acceleration curve.

[0045] S500, the parameter-time acceleration curve data is transmitted to the material corrosion failure test device terminal.

[0046] It can be understood that the material corrosion failure test device terminal can send instructions and receive data, that is, receive parameter-time acceleration curve data, etc., and control the material corrosion failure test device simulation environment and perform tests.

[0047] S600, according to the parameter-time acceleration curve data, the material corrosion failure test device terminal adjusts the temperature, humidity, light intensity, wind speed and particulate matter concentration in the material corrosion failure test device to simulate the industrial dust environment and perform corrosion failure test on the material sample.

[0048] Specifically, S610, when the temperature T in the material corrosion failure test device ≠ T0±1℃, the temperature control system in the material corrosion failure test device is used for temperature adjustment, so that the temperature T = T0±1℃; wherein, T0 is the target temperature value of the material corrosion failure test device currently preset, which is determined according to the temperature-time acceleration curve.

[0049] Specifically, S620, when the humidity RH in the material corrosion failure test device ≠ a±5%, the humidity control system in the material corrosion failure test device is used for humidity adjustment, so that the humidity RH = a±5%; wherein, a is the target humidity value of the material corrosion failure test device currently preset, which is determined according to the humidity-time acceleration curve.

[0050] Specifically, S630, according to the light intensity-time acceleration curve, the target light intensity value of the current material corrosion failure test device is determined; S631, through the light control system in the material corrosion failure test device, the current light intensity in the material corrosion failure test device is adjusted to the target light intensity value.

[0051] Specifically, S640, according to the wind speed-time acceleration curve and the particulate matter concentration-time acceleration curve, the target wind speed value and the target particulate matter concentration value of the current material corrosion failure test device are determined; S641, through the air volume control system in the material corrosion failure test device, the current wind speed in the material corrosion failure test device is adjusted to the target wind speed value; S642, by starting the fan in the air volume control system, the particulate matter in the particulate matter storage and recovery system in the material corrosion failure test device is blown up to simulate the dust environment.

[0052] It should be noted that in the material corrosion failure test device of the present application, the particulate matter is stored in the sand storage tank, the sand storage tank is in communication with the air conveying pipeline, when the fan is started, the air output by the fan is output through the air conveying pipeline, at the same time of manufacturing the target wind speed value, the particulate matter in the sand storage tank is blown up, simulating the industrial dust environment. When the fan is disabled, these particulate matters will fall back to the sand storage tank due to the action of gravity.

[0053] The present application also provides a material corrosion failure test device for simulating an industrial dust environment, which is used to realize the material corrosion failure test method for simulating an industrial dust environment as described above, and the device comprises:

[0054] A temperature control system for adjusting the temperature in the material corrosion failure test device;

[0055] A humidity control system for adjusting the humidity in the material corrosion failure test device;

[0056] A light control system for adjusting the light intensity in the material corrosion failure test device;

[0057] An air volume control system for adjusting the wind speed in the material corrosion failure test device;

[0058] A particulate matter storage and recovery system for adjusting the particulate matter concentration in the material corrosion failure test device.

[0059] Specifically, the temperature control system comprises an evaporator, a condenser, a compressor, a throttle valve, a heating pipe and a temperature sensor.

[0060] It should be noted that the temperature sensor is responsible for monitoring the temperature in the test chamber in real time, and converting the temperature value into an electrical signal to provide feedback to the material corrosion failure test device terminal. The material corrosion failure test device terminal receives signals from the temperature sensor and processes them according to the preset target temperature value. If there is a deviation between the actual temperature and the set value, the material corrosion failure test device terminal will issue instructions to adjust the temperature. The compressor is responsible for compressing the refrigerant, increasing its pressure and temperature, and providing power for subsequent heat exchange. After the compressor, the high-temperature and high-pressure refrigerant enters the condenser, releasing heat to the surrounding environment, and changing from a gaseous state to a high-pressure liquid state. The throttling valve (such as an electronic expansion valve) controls the flow of refrigerant into the evaporator, while reducing the pressure, so that the liquid refrigerant evaporates in the evaporator and absorbs heat, thereby achieving the refrigeration effect. When the refrigerant absorbs heat and evaporates in the evaporator, the temperature of the surrounding medium (such as air) decreases, thereby achieving refrigeration. When heating is needed, the heating pipe converts electrical energy into heat energy, inputting heat into the test chamber to increase the temperature inside the chamber. In summary, the temperature control system monitors the ambient temperature through the temperature sensor, and the material corrosion failure test device terminal issues instructions based on the deviation between the set value and the actual value. Through the coordinated work of the compressor, condenser, throttling valve and evaporator, refrigeration is achieved, and the heating pipe is used for heating. The entire system realizes closed-loop control, that is, the temperature information monitored by the temperature sensor is continuously fed back to the terminal, and the terminal adjusts the operation of the heating pipe and the refrigeration system according to these information to achieve precise control of the temperature inside the test chamber. Such a system design can simulate different temperature conditions to meet the temperature requirements of material corrosion failure tests.

[0061] Specifically, the humidity control system includes a water pump, a water tank, an ultrasonic atomizer, and a humidity sensor.

[0062] It should be noted that the humidity sensor monitors the humidity level in the test chamber in real time, and converts the monitored humidity value into an electrical signal to feed back to the material corrosion failure test device terminal. The material corrosion failure test device terminal automatically adjusts the working state of the ultrasonic atomizer according to the difference between the set target humidity value and the actually detected humidity value. When the humidity in the chamber is lower than the set value, the control system starts the water pump to deliver water in the water tank to the ultrasonic atomizer. The ultrasonic atomizer uses ultrasonic waves generated by high-frequency vibration to vibrate water molecules into tiny water droplets, which are then blown out by the fan and quickly evaporated, increasing the humidity of the air. If the humidity in the chamber exceeds the set value, the material corrosion failure test device terminal may start a dehumidification mechanism, such as condensation or adsorption, to remove excess moisture and reduce humidity. Throughout the process, the humidity sensor continuously monitors humidity changes to ensure that humidity is maintained within the set range. Through this closed-loop control method, the humidity control system can accurately control the humidity in the test chamber, providing suitable environmental conditions for material corrosion failure tests.

[0063] Specifically, the light control system includes a light source assembly and a second light intensity sensor.

[0064] It should be noted that the device monitors the current light intensity in the device in real time through the second light intensity sensor, and converts the monitored light intensity value into an electrical signal to feed back to the material corrosion failure test device terminal. The material corrosion failure test device terminal automatically adjusts the working state of the light source assembly according to the difference between the set target light intensity value and the actual detected light intensity value.

[0065] Specifically, the air volume control system includes a fan, an air volume regulating valve, and an air speed sensor.

[0066] It should be noted that the fan is responsible for generating airflow, and its speed can be adjusted by a frequency converter or other control equipment to change the air volume and air speed. The air speed sensor monitors the air speed in the test box in real time, and converts the monitored air speed value into an electrical signal to feed back to the material corrosion failure test device terminal. The material corrosion failure test device terminal automatically adjusts the opening of the air volume regulating valve and the speed of the fan according to the difference between the set air speed value and the actual detected air speed value. When the actual air speed is lower than the set value, the material corrosion failure test device terminal will increase the opening of the air volume regulating valve and / or increase the speed of the fan to increase the air speed; when the actual air speed is higher than the set value, the material corrosion failure test device terminal will decrease the opening of the air volume regulating valve and / or decrease the speed of the fan to decrease the air speed. This closed-loop control method ensures that the air speed can be accurately controlled within the required range, thereby providing stable air speed conditions for material corrosion failure testing. In this way, the air volume control system can accurately adjust the air speed according to the test requirements, simulating different industrial dust environment conditions.

[0067] Specifically, the particulate matter storage and recovery system includes a sand storage tank, a sand receiving tray, and a filter screen.

[0068] It should be noted that in the material corrosion failure test device of the present application, the particulate matter is stored in the sand storage tank, which is in communication with the air conveying pipeline. When the fan is turned on, the air output by the fan is output through the air conveying pipeline, which blows up the particulate matter in the sand storage tank while creating the target air speed value, simulating the industrial dust environment. After the fan is turned off, these particulate matters will fall back into the sand storage tank due to gravity. In particular, the particulate matter in the sand storage tank includes but is not limited to coal mine dust, iron mine dust, aluminum mine dust, copper mine dust, and urban environment dust (eastern, central, and western), which can be selected according to the simulation requirements.

[0069] The working principle of the material corrosion failure test method and device for simulating industrial dust environment according to the present application is as follows:

[0070] The application discloses a material corrosion failure test method in simulated industrial dust environment, which comprehensively considers various environmental factors, especially the influence of particulate matter concentration on material corrosion, can more accurately simulate the complex corrosion process of materials in actual industrial environment, and has higher acceleration and correlation compared with traditional single-factor environment simulation accelerated test technologies, such as salt spray test, light aging test and damp heat test, and can more accurately evaluate the service life of the material. In addition, the application collects various environmental factor parameters in outdoor actual industrial dust environment, and realizes indoor accelerated test through the parameters, simulates material corrosion failure in industrial dust environment, can establish an equivalent relationship with outdoor empirical test, can better predict the service behavior of the material in the actual industrial environment, and thus provides a scientific basis for material selection and protection strategy formulation, which has a significant effect on improving the accuracy of electrical equipment life evaluation.

[0071] The above is only a preferred embodiment of the application, and does not limit the application in any form, so any modification, equivalent change and modification of the above embodiment without departing from the technical solution of the application, according to the technical essence of the application, all still belong to the scope of the technical solution of the application.
