摘要： PROBLEM TO BE SOLVED: To sequentially operate a plurality of submergible pumps coupled in series in such a proper timing that bad conditions such as inability of discharge due to crush of a drainage hose, pump failure, etc., are not generated. SOLUTION: When a plurality of submergible pumps 2 submerged into water from a drainage cart coupled in series are successively started from a preceding pump 2A positioned upstream in the drainage direction to a following pump 2B positioned downstream, the water level discharged into a drainage hose 6 from the preceding pump 2A is detected by a operation signal of a pressure sensor 21 so as to judge whether or not the water level has reached a required suction level for the following pump 2B. The following pump 2B is automatically started based on the water detection signal by a portable wireless controller 15 which can receive and send radio signals to an operation control board 5 or the drainage pump cart 1.

摘要： PROBLEM TO BE SOLVED: To provide a water turbine facility having a siphon type suction water channel which shortens a starting time and which simplifies a system, and to provide a method for operating the same.
SOLUTION: The suction duct 11 of a water turbine 12 is installed so that the suction duct 11 is once routed through the position higher than the high water level of a suction water level 1, and then the suction side end is submerged in the suction water level 1. An air purge means 20 having an opening/closing valve 21 and an air purge tube 22 is mounted at the highest position of the suction duct 11, and a check valve 15 for passing the water only in the direction of the water turbine 12 is mounted at the suction side of the suction duct 11. At the starting time, a motor-cum-generator 14 coupled to the water turbine 12 is driven as a motor to perform a pumping action. Thus, the water of a discharge duct 13 side is reversely fed toward the suction duct 11, and the air in the suction duct 11 is extracted through the air purge means 20. When the suction duct 11 is fully filled with the water, the air purge means 20 is closed to stop the pumping action, the water is automatically supplied to the water turbine 12 by the siphon action, and the operation of the water turbine is started.
