630E卡车电动轮定子线包更换改进工艺

为解决黑岱沟露天矿630E矿用卡车电动轮定子线包更换困难的问题以及满足露天煤矿岗位标准作业流程和受限空间作业基本要求,提出了新的更换改进工艺标准,并制作水平Y型更换工装,充分利用定子线包自重来进行更换。结果表明:此工艺不仅保证了作业人员和设备的安全,还大大的提高了检修效率,为露天矿节约了大量检修成本。

TK5200－18／2600同步电机定子故障应急检修

2012年8月，1台5500kW同步电机运行过程中有1只定子线包突然被击穿，绝缘体损坏，导致设备停运。该同步电机外形较大，检修周期较长（约1个月），会影响生产。为此，决定先对该同步电机作应急检修，等待机会再进行彻底检修。

Target Seeker Gyro and Controls

A composite target seeker gyro with dual spectral range infrared rays and millimeter waves, and the associated control methodology are developed. The static pressure air floated ball bearing is used to sustain the outer frame, the optical fiber and wave guide are used to transmit these two kinds of signals to the rear part of the gyro, and the stator coils are used to get non contact angular measurement. Composite guiding, scanning, tracing and controlling can be achieved, the maximum tracing angular velocity can be as high as 16(°)/s.
