Hydraulic lifting unwinding rack, equipped with auto tension and computer deviation correcting system.
液压提升放卷架并配有自动张力及电脑纠偏系统。
By the feedback test of computer system, the deviation has been verified and such optimum operational program that could control the minimum operation cost has been set up.
通过计算机系统的反馈验证，找出了偏差并制定了能控制最小运行费用的新优化运行方案。
During the welding process, the computer will modify the position of the electron gun based on the deviation to make the electron beam spot centered on the annular weld groove.
在焊接时利用处理后的偏差值在圆形焊缝相应位置不断修正电子枪的位置，从而达到电子束束斑与焊缝自动对中的目的。
