    • PROBLEM TO BE SOLVED: To easily remove foreign matter without requiring a flow control function and a special foreign matter discharging mechanism.
      SOLUTION: First, an inlet valve is closed by a valve control part to stop the supply of a pressurized water to a water turbine (S101). Next, the water turbine is rotated in the reverse direction by a rotation control part (S102). Then, the water turbine is rotated to a matching position by a positioning control part and stopped at the matching position by a rotation stop control part (S104). The inlet valve is opened by the valve control part to supply pressurized water to the water turbine (S105). After a predetermined time is passed, the inlet valve is closed again by the valve control part to stop the supply of pressurized oil to the water turbine (S106). The water turbine is rotated in the rotating direction by the rotation control part (S107). The treatments S103 to S107 are repeated several times.

    • 要解决的问题:为了容易地除去异物而不需要流动控制功能和特殊的异物排放机构。 解决方案:首先,进气阀由阀门控制部分关闭,以停止向水轮机供应加压水(S101)。 接下来,水轮机通过旋转控制部沿反方向旋转(S102)。 然后,通过定位控制部将水轮机转动到匹配位置,并通过旋转停止控制​​部而在匹配位置停止(S104)。 入口阀由阀控制部分打开以向水轮机供应加压水(S105)。 在经过预定时间之后,阀门控制部分再次关闭入口阀,停止向水轮机供应加压油(S106)。 水轮机通过旋转控制部沿旋转方向旋转(S107)。 处理S103〜S107重复多次。 版权所有(C)2007,JPO&INPIT

    • PURPOSE: To control the hydraulic pressure stably and reliably in the case of high head pump water wheel with S-character by detecting the fact that the operation status of water wheel is proceeding in the direction of flow reduction on the S- character.
      CONSTITUTION: When the pump water wheel with S-character in which a flow rate and torque are dropped according to the reduction of that N
      1 = N/(H)
      1/2 (N; the number of rotation, H; effective head) is provided and the operation status of water wheel is proceeding in the direction of flow or torque decrease on the S- character, the guide blade is opened, the extent of S-character is reduced and the closing speed of guide blade is restricted to avoid the abrupt variation of operation status. The fact that the operation status of water wheel is proceeding in the direction of a flow decrease on the S-character is approximately detected according to the combination of the number of rotation N with the acceleration dN/dt, the solenoid value 6 is changed to control the servomotor of the guide blade.

    • 目的:通过检测水轮的运行状态在S字符的流动方向上进行的事实,可以在具有S字符的高头泵水轮的情况下,稳定可靠地控制液压。 构成:当根据N1 = N /(H)1/2(N,旋转次数H,有效头数)的减少,具有S字符的泵水轮,其中流量和扭矩下降时 ),水轮的运行状态在S字符的流向或转矩减少方向上进行,导向叶片打开,S字符的扩展程度减小,导向叶片的关闭速度被限制在 避免操作状态突然变化。 根据旋转数N与加速度dN / dt的组合,大致检测出水轮在S字符上的流动方向上的运行状态的减少的事实,螺线管值6变为 控制导向叶片的伺服电机。
