摘要： PURPOSE: To eliminate the sharp change in the flow of a fluid in a scoop-up tube chamber, prevent a separation flow and eliminate the unstable region of output rotational frequency, by opening a plurality of holes through a partition plate between the working chamber and scoop-up tube chamber of a fluid joint to connect the chambers to each other.
CONSTITUTION: The working chamber 5 of a fluid joint is defined by an impeller 2 coupled to an input shaft 1 and a runner 3 coupled to an output shaft 4. A scoop- up tube 8 is provided in a casing 6 at the side of the impeller 2. The casing 6 is divided by a partition plate 7 to define a scoop-up tube chamber 9. The partition plate 7 is provided with a plurality of communication holes 10 to prevent the separation flow in the scoop-up tube 8.

摘要： PURPOSE: To reduce remarkably the fluctuation in the rotating speed of the output shaft in the captioned supplier used in a reactor power station, by connecting suction sides of both a normal hydraulic pump and a spare hydraulic pump, thereby removing air reserved in the spare hydraulic pump.
CONSTITUTION: The working oil flowing from an oil tank through an inlet port 24 is pressurized by a normal hydraulic pump 13 and delivered to an impeller side th rough a delivery port 25. The air reserved in the low-pressure side of a space hydraulic pump out of operation is sucked out by the suction (negative) pressure created in the suction side of the normal hydraulic pump 13 under operation. By setting the pressure at a low-pressure side circuit 15 of the normal hydraulic pump 13 under operation to approx. -0.1kg/cm
2 .g by means of a throttle 19, and by setting the pressure of the spare hydraulic pump 14 out of operation to approx. 0.1kg/cm
2 .g by means of a throttle 20, the air can be flowed effectively.
