管端除锈设备自动控制设计

介绍了一种新型螺旋埋弧焊管管端除锈设备的构造和功能，阐述了其工作原理，并基于西门子S7—200 PLC 设计了除锈设备的全自动控制工艺。经过实际生产应用证明，管端除锈设备的自动控制设计提高了工作效率，维修、维护方便，故障率降低，更有利于HSE现场管理，避免了人工操作的不稳定因素，降低了劳动力成本，保证了管端除锈质量的稳定，同时，避免了母材划伤，提高了除锈质量，在同行业中具有很好的推广应用价值。

Automatic Control Design of Rust Removing Device for Pipe End

In this article， it introduced the structure and functions of a new kind of SAW pipe end rust removing device， and expounded its working principle. At the same time， the full-automatic control technology of rust removing was designed based on SIEMENS S7-200 PLC. The productive practice proved that this automatic control design increased production efficiency， reduced failure rate and work labor cost， avoided unstable factors of manual operation， and realized stable rust removing quality.It was in favour of HSE field management， and simple maintenance. Meanwhile， it avoided base metal scratch， increased rust removing quality. So it is applicable to widely promote in SAWH pipe industry.
