水动机组同步是靠控制杆通过压块压迫截流阀调节进入液压缸的水量来实现的。当塔架超前如图1时(图中弓形表示塔架超前引起的弯曲,虚线表示直线位置,C、B 为传动杆,A 为控制杆),由于水管前弯曲传动杆 B、C 将控制杆向后拉,压块松开截流阀顶杆阀门7(图3)将关闭一部分,减少进入液压缸的水量,机组速度减慢;当塔架落后则主水管发生后弯曲(图2),控制杆被传动杆向前推,压块压迫截流阀水量加大,机组速度加快。 Synchronization of hydrodynamic units is achieved by controlling the amount of water entering the cylinder by the control block by the pressure block shut-off valve. When the tower ahead of Figure 1 (Figure arches that led tower ahead of the bend, the dotted line indicates the position of the line, C, B for the transmission rod, A for the control rod), because the water before bending the transmission rod B, C control lever (Figure 3) will close some, to reduce the amount of water into the hydraulic cylinder, the unit slows down; when the tower behind the main water pipe bend (Figure 2), the control The lever is pushed forward by the transmission rod, the pressure of the compression blocker valve is increased, and the speed of the unit is increased.
