| Abstract: |
| Objective To accelerate the corrosion of pipeline inner wall, study the influence of corrosion factors on corrosion mechanism and corrosion behavior of pipeline inner wall, and design a pipeline erosion-corrosion apparatus independently. Methods The apparatus belongs to mechatronics product which includes the overall structure design as well as hardware design and software design of the control system. PLC was used as the central processing unit and touch screen was used as the man-machine interface in the control system. The temperature and flow rate of corrosion factors were regulated. In addition, the performance of the device was tested. Results The control precision of temperature could be -0.5℃ to +0.8℃; and the control precision of flow velocity could reach ±0.01m/s. Conclusion The device has reliable operation, wide testing range and good performance, which establishes the experimental foundation for studying the erosion-corrosion of pipeline. |
