摘要:

对某水电厂排漂孔弧形闸门运行中出现同步超差的原因进行了分析,通过预先给予开度偏差补偿,减小了偏载量。对于刚性较好的双吊点弧形闸门,应采用刚性同步回路或负载平衡控制方式,支铰应采用圆柱铰或圆锥铰。这样,双吊点弧形闸门同步超差就比较容易控制。

Abstract: The reason of too large synchronous error occurred in operation of the radial gate of the floatage drains of a hydropower plant was analyzed. Using the beforehand given deviation compensation of the opening, the load deviation value was decreased. For the radial gate with dual lifting point, which has better rigidity, the rigid synchronous loop or load balance control mode should be adopted; and the cylindrical hinge or cone hinge should be used as supporting hinge. Thus, the too large synchronous error will be controlled more easily.
