【摘要】：隨著經(jīng)濟的發(fā)展,能源需求的增加,作為能源輸送載體的管道工程得到了長足的發(fā)展。清管技術(shù),作為保障管道安全可靠運行提高管道運行技術(shù)經(jīng)濟效益的重要技術(shù)措施之一,也得到了廣泛的應(yīng)用與發(fā)展。 清管器是清管技術(shù)的重要組成部分,其在流體壓力的驅(qū)動下在管道中運動,利用其與管道之間的摩擦、刮削作用清洗管道,且可在運動過程中利用相關(guān)檢測儀器完成對管道的檢測。清管器類型繁多,結(jié)構(gòu)不一,其中應(yīng)用得較為廣泛的是芯軸式清管器。 芯軸式清管器由鋼軸、皮碗以及其他清洗檢測部件構(gòu)成。皮碗是芯軸式清管器的重要部件,其與管道之間過盈配合,從而完成密封流體形成驅(qū)動力與刮削管壁清洗管道并推動污垢前進這兩方面的功能。然而,目前在實際運用中對皮碗的設(shè)計與選用還主要依靠工程經(jīng)驗,故有必要對皮碗的性能進行深入的分析研究。 首先,對芯軸式清管器進行了動力分析,得到了基于假設(shè)條件的運動方程,并知曉了影響芯軸式清管器運動的相關(guān)因素。同時,還對芯軸式清管器在三通與彎管中的通過能力進行了分析。 其次,從皮碗的結(jié)構(gòu)類型與連接方式出發(fā),對皮碗進行了受力分析,得到了皮碗的受力模型以及簡化條件下的理論計算公式。并綜合以上兩個部分得到了皮碗的性能主要體現(xiàn)為與管道之間的相互作用情況,同時,分析了影響皮碗接觸性能的相關(guān)因素。 最后,結(jié)合上述的分析,從兩個方面對皮碗的接觸性能進行了研究：一是皮碗本身結(jié)構(gòu)；二是皮碗的工況條件。皮碗本身結(jié)構(gòu)方面,分析得到了皮碗在不同過盈量、不同厚度、不同唇長時的相關(guān)性能的值以及其變化的規(guī)律；皮碗工況條件方面,分析得到了皮碗在不同壓差、不同管徑以及通過焊縫余高時相關(guān)性能的值以及其變化規(guī)律。
[Abstract]:With the development of economy and the increase of energy demand, pipeline engineering, which is the carrier of energy transmission, has made great progress. As one of the important technical measures to ensure the safe and reliable operation of pipeline, it has been widely used and developed. Pipe-cleaner is an important part of pipe-cleaning technology. It moves in the pipeline driven by fluid pressure and cleans the pipeline by the friction between it and the pipe. It can be used in the process of movement to complete the inspection of the pipeline. There are many types and different structures of the pipe cleaner, among which the core shaft type pipe cleaner is widely used. The core shaft type pipe cleaner is composed of steel shaft, leather bowl and other cleaning and detecting parts. The leather bowl is an important part of the core shaft type pipe cleaner, which fits with the pipe. In order to complete the sealing fluid formation driving force and scraper pipe wall cleaning pipe cleaning and promote fouling advance of the two functions. However, in practical use, the design and selection of leather bowls mainly rely on engineering experience. Therefore, it is necessary to the performance of leather bowls in-depth analysis and research. First of all, the dynamic analysis of the core shaft cleaner is carried out, and the motion equation based on the hypothetical condition is obtained, and the relevant factors affecting the movement of the core shaft cleaner are known. At the same time. The passage ability of the core shaft type pipe cleaner in three-way and bend pipe is also analyzed. Secondly, from the point of view of the structure type and connection mode of the leather bowl, the force of the leather bowl is analyzed. The mechanical model of the cup and the theoretical calculation formula under the simplified conditions are obtained. The performance of the leather bowl is mainly reflected in the interaction between the pipe and the pipe, and at the same time, the performance of the leather bowl is obtained by synthesizing the above two parts. The related factors affecting the contact properties of leather bowls were analyzed. Finally, based on the above analysis, the contact properties of the leather bowls are studied from two aspects: first, the structure of the leather bowls; Second, the operating conditions of the leather bowl. In terms of the structure of the leather bowl itself, the relative performance of the leather bowl with different interference amount, different thickness and different lip length was obtained and the law of its change was obtained. In terms of the working conditions of the leather bowl, the relative performance of the leather bowl under different pressure differences, different pipe diameters and the residual height through the weld seam was obtained and its variation law was obtained.
