摘要： PROBLEM TO BE SOLVED: To provide a thin pump gate capable of thinning and keeping good balance of weight. SOLUTION: A drainage pump V is incorporated into a frame body of a gate for opening and closing a channel, the pump V is connected to a driver 23 through a power transfer mechanism (decelerator) 21, and water in one side of the closed channel is discharged by driving the pump V with the driver 23 in a state to close the channel. The pump V is so set that a rotary shaft 20 thereof is approximately parallel with the flow of the channel. The power transfer mechanism 21 is so constituted that the power is transferred within an approximately vertical plane to the flow of the channel. The driver 23 is installed at a position between a skin plate 351 of the gate and power transfer mechanism 21.

摘要： PROBLEM TO BE SOLVED: To provide a pump gate facility which can omit a combination test in the factory even if a pump and a gate are manufactured in different factories, contributes to reduction in transportation and inspection costs, and ensures its gate function even after removal of the pump from the gate by leaving a check valve in the gate even in the case where the pump undergoes a failure after setting and is taken away to the factory to be repaired.
SOLUTION: According to the pump gate installation which is constructed such that the gate 2 for opening/closing a channel 1 is provided with the pump 4 and the check valve 5 and that water in one part of the channel 1 blocked with the gate 2 is pumped up by the pump 4 to be discharged to the other part of the channel via the check valve. Herein a skin plate as a water cutoff plate of the gate 2, is provided with a base plate 10, and the pump 4 is combined with the check valve 5 via the base plate 10. Further the pump 4 and the check valve 5 are individually and detachably mounted on the base plate 10 at connection locations different from each other.

摘要： PROBLEM TO BE SOLVED: To provide a submergible motor pump easily and smoothly startable without arranging expensive equipment, reducing the size and causing no damage of a motor. SOLUTION: A motor shaft 5 driven by the motor M is formed as a hollow shaft, and a pump shaft 6 for driving the pump P is inserted into the motor shaft 5. Torque of the motor shaft 5 is transmitted to the pump shaft 6 via a continuously variable transmission T. The transmission ratio of the continuously variable transmission T is steplessly changed so that starting of the pump P and operation thereafter can be smoothly and efficiently performed.
