山东理工大学 毕业设计（论文） 题 目： 钻通机的设计 学 院： 机械工程学院 专 业： 机械设计制造及其自动化 学生姓名： 王恒 指导教师： 王勇 毕业设计（论文）时间：二О一一 年 三 月 二十三 日～ 六 月 十 四日 共 十二 周 摘要 在旧油管清洗过程中，致密坚硬的污垢、锈皮采用单一的高压水射流清洗时，所需的射流压力大，采用油管钻通机进行预清洗。介绍了油管钻通机的清洗原理、结构特点、以及关键技术。油管钻通机和高压水射流内清洗线配合使用，可大大提高钻通清洗效率以及清洗合格率。 由于绝大多数注水井回收油管表面垢层的主要成分是CaCO3、CaSO4，并有少量的Fe2O3、BaSO4、SrSO4等成份，致密坚硬。采用单一的高压水射流清洗时，压力必须达到70MPa以上才能清洗干净甚至有些硬厚水垢、锈皮需要150MPa以上的高压水才能清洗干净，在这么高的压力下工作，对操作工人的安全是一个很大的考验。这就要求在对油管进行高压水射流清洗之前进行预清洗，降低射流水的压强，传统的预清洗有中频感应加热预清洗、远红外预热清洗、机械预清洗等几种清洗方法，中频加热预清洗虽然能量集中、速度快，但功效大难于控制，并伴有烟尘污染。机械钻通机清洗具有清洗效率高、环保等优点，得到了广泛的使用。 关键词：油管；预清洗；钻通；环保 Abstract In The harmonic putter technology is improved on the base the old pipe cleaning process, the hard compact dirt, rust leather with a single high pressure water jet cleaning, the required jet pressure, the use of tubing drill through pre-cleaning machine. Introduced through tubing drilling machine cleaning principle, structural features, and key technologies. Tubing drilling through high pressure water jet machine and clean the lines with the use, can greatly improve the cleaning efficiency and cleaning drill through the pass rate. Since most recovery injection well tubing surface layer of the main component of scale CaCO3, CaSO4, and a small amount of Fe2O3, BaSO4, SrSO4 and other ingredients, compact and hard.A single high-pressure water jet cleaning, the pressure to reach more than 70MPa to clean and even some hard and thick scale, rust, skin needs more than 150MPa high pressure water to clean, in working under such high pressure, the safety of workers on the operation of a Great test. This requires high-pressure water jet for cleaning the tubing before the pre-cleaning, reducing the pressure jets. The traditional pre-cleaning pre-wash with medium frequency induction heating, far infrared warm-cleaning, mechanical cleaning methods, such as several pre-cleaning, Although pre-cleaning frequency heating energy concentrat
