摘要
管道在安装前都需要进行坡口加工,坡口加工质量优劣直接影响焊接质量。对常用坡口加工机具及其加工质量进行了比较分析,阐述了电动管端坡口机的结构组成和工作原理。应用效果显示:电动管端坡口机在铬钼耐热合金钢管焊接工序中加工出来的坡口平整光亮,保证了焊接质量,省时高效,避免了采用其他方式加工坡口造成的各种质量问题。而且针对钢质管道安装维修特点,提出采用直流电机和便携式锂离子电源,省时高效、经济环保。
Before pipeline installation, the pipe need bevel process, and bevel machining quality directly affects welding quality. In this article, it made a comparative analysis on the common bevel processing equipment and its processing quality, and expatiated the structure and working principle of electricity motor driving pipe end beveling machine. The application results indicated that the bevel is smooth and bright by using electricity motor driving pipe end beveling machine in Cr-Mo heat-resistant alloy steel pipe welding process. It ensures the welding quality, time-saving and efficient, avoiding various quality problems caused by other methods of processing bevel. According to the characteristics of the pipeline installation and maintenance, it put forward using DC motor and portable lithium-ion power resource, it is with time-saving and efficient, economic and environmental protection.
