【摘要】：隨著我國(guó)國(guó)民經(jīng)濟(jì)的高速發(fā)展,石油及石油制品已經(jīng)慢慢成為主要的能源及化工原料。我國(guó)現(xiàn)在主要的原油運(yùn)輸有兩種,一種是輸油管線；另一種則是油罐車運(yùn)輸。由于運(yùn)輸?shù)脑椭型辛蛩�、氫、有機(jī)鹽和無(wú)機(jī)鹽以及水分等具有腐蝕性的化學(xué)物質(zhì),加上儲(chǔ)油罐外壁受周圍環(huán)境因素的影響,儲(chǔ)油罐的壽命將會(huì)大大減少。如果不能及時(shí)的對(duì)儲(chǔ)油罐進(jìn)行腐蝕檢測(cè),并對(duì)有腐蝕情況的儲(chǔ)油罐進(jìn)行處理,后果將非常嚴(yán)重,輕則影響油品質(zhì)量,重則會(huì)造成油品泄露,環(huán)境污染,而且容易造成火災(zāi)和爆炸。按照調(diào)查數(shù)據(jù)顯示,世界上工業(yè)發(fā)達(dá)的國(guó)家因儲(chǔ)油罐腐蝕造成的經(jīng)濟(jì)損失約占當(dāng)年國(guó)民生產(chǎn)總值的1.8%—-4.2%；我國(guó)每年因?yàn)楦g引起的損失估計(jì)達(dá)5000億元,約占國(guó)民經(jīng)濟(jì)生產(chǎn)總值的5%。因此,對(duì)儲(chǔ)油罐的腐蝕檢測(cè)具有非常重要的意義。本文按照已有的各種針對(duì)腐蝕檢測(cè)的傳感器的特點(diǎn)進(jìn)行分析,設(shè)計(jì)并研制了一種用于儲(chǔ)油罐腐蝕檢測(cè)的電渦流傳感器。首先,因此油罐車罐體的尺寸太大,本文將其網(wǎng)格劃分成了許多塊20×20(mm),厚度為5mm的碳鋼板,然后對(duì)油罐車的渦流檢測(cè)原理進(jìn)行了分析,并對(duì)電渦流傳感器進(jìn)行了等效電路分析,并按照等效電路研究了線圈和被測(cè)材料的各參數(shù)對(duì)檢測(cè)結(jié)果的影響。然后根據(jù)激勵(lì)線圈和檢測(cè)線圈在檢測(cè)系統(tǒng)中作用的不同,確定了它們的形狀和電渦流傳感器結(jié)構(gòu),并通過(guò)有限元分析確定了激勵(lì)線圈和檢測(cè)的尺寸,接著對(duì)罐體金屬材料的屬性和趨膚深度研究,得出了本論文電渦流傳感器的激勵(lì)頻率。然后通過(guò)計(jì)算,得到了激勵(lì)線圈和檢測(cè)線圈的漆包線線徑和匝數(shù),并且根據(jù)線圈的尺寸設(shè)計(jì)骨架和外殼。其次,根據(jù)分析結(jié)果設(shè)計(jì)并制作了探頭線圈以及激勵(lì)探頭線圈的信號(hào)發(fā)生器,并按照輸出信號(hào),設(shè)計(jì)了傳感器的后置電路并進(jìn)行了仿真。然后對(duì)具體的不同深度腐蝕情況的試件進(jìn)行了測(cè)試,得出測(cè)試結(jié)果并記錄分析。
[Abstract]:With the rapid development of China's national economy, petroleum and petroleum products have gradually become the main energy and chemical raw materials. There are two main types of crude oil transportation in China, one is pipeline, the other is tanker transportation. Due to the corrosive chemical substances such as sulfuric acid, hydrogen, organic salt, inorganic salt and water in the transported crude oil, the life of the oil storage tank will be greatly reduced due to the influence of environmental factors on the outer wall of the oil storage tank. If it is not possible to detect the corrosion of the oil storage tank in time, and to deal with the oil storage tank with corrosion, the consequences will be very serious. The light will affect the quality of the oil product, and the heavy will cause oil leakage and environmental pollution. And easy to cause fire and explosion. According to the survey data, the economic losses caused by the corrosion of oil storage tanks in industrialized countries in the world accounted for about 1.8-4.2 percent of the GNP in that year. The losses caused by corrosion in China are estimated at 500 billion yuan each year. It accounts for about 5% of the gross national product. Therefore, it is of great significance to detect the corrosion of oil storage tanks. In this paper, according to the characteristics of various kinds of existing sensors for corrosion detection, a eddy current sensor for oil tank corrosion detection is designed and developed. First of all, the size of the tank is too large. In this paper, the grid is divided into many carbon steel plates with a thickness of 5mm and 20 脳 20mm, then the eddy current detection principle of the tank is analyzed, and the equivalent circuit of the eddy current sensor is analyzed. According to the equivalent circuit, the influence of the parameters of the coil and the tested material on the test results is studied. Then according to the different function of the excitation coil and the detection coil in the detection system, the shape and the structure of the eddy current sensor are determined, and the size of the excitation coil and the detection coil are determined by the finite element analysis. Then, the characteristics and skin depth of metal materials are studied, and the exciting frequency of eddy current sensor is obtained. Then the diameter and turns of the enamelled wire of the exciting coil and the detecting coil are obtained, and the skeleton and shell are designed according to the size of the coil. Secondly, according to the analysis results, the signal generator of probe coil and excitation probe coil is designed and manufactured. According to the output signal, the post-circuit of sensor is designed and simulated. Then, the concrete specimens with different corrosion depth were tested, the test results were obtained and the analysis was recorded.
