Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of loop even under the severe hydrographic conditions by floating at least predetermined number of pieces of hoses counted from a single point mooring buoy under the sea surface by using submarine hoses. SOLUTION: At least four marine hoses counted from a single point mooring buoy 2 is submerged under the sea surface.

Filed: 1982-11-05
Abstract: PURPOSE:To improve the water thrusting property of a hydraulic machine and reduce its leak water loss, by providing a draining means between a main shaft seal and a sealing means provided between a runner and the main shaft seal, to drain a fluid having leaked along the sealing means, to lower the static pressure on the main shaft seal at the side of the runner. CONSTITUTION:A pipe 17 for draining a fluid having leaked along a sealing means 16 is provided between a main shaft seal 7 and the sealing means 16 which is provided between the main shaft seal and a high-pressure stage runner 2a, to reduce the pressure on the sealing means 16 to lower the static pressure of a space 14 between the main shaft seal and the runner. Although the amount of water drained through the pipe 17 is small, the pressure drop based on the sealing means 16 is so large that the static pressure of the space 14 between the main shaft seal 7 and the runner 2a can be lowered without much changing the static pressure of back pressure chambers 3a, 4a. As a result, a good water thrusting property is achieved. Since the amount of water drained through the pipe 17 is small, the water leak from the runner 2a can be made low.
