Abstract
PURPOSE: To install a closed oil sealing tank at will and obtain a sufficient shaft sealing effect, by providing the tank near a pump and always automatically controlling the pressure in the tank above the value corresponding to the inside and outside water levels.
CONSTITUTION: Shaft seals 3, 3' are provided at both the sides of a shaft 2 which supports moving blades 1. Shaft sealing oil O in the shaft seals is connected to shaft sealing oil O in the sealing oil tank 6 located near the axial-flow pump 5. The tank 6 is of the closed type. An air pipe 11 is connected to the upper part of the tank 6 to supply air A of pressure higher than the discharge pressure of the pump 5 from an air compressor 10 through a pressure regulating valve 7. An end of an air purge pipe 8 coupled to the upper part of the tank 6 through a check valve 9 is opened into the discharge pipe 12 of the axial-flow pump 5. As a result, the oil sealing tank 6 can be installed at will and the shaft is effectively sealed up.
