Abstract

PURPOSE: To enable to operate plural pumps in parallel and to control the number of pumps operated, by a method wherein check valves are provided in suction pipes, and plural pumps are connected with each other through a pressure equalizing pipe.
CONSTITUTION: The check valves 15 and feed water pumps 13 are provided in suction pipes 12a, and the pumps 13 are connected with each other through the pressure equalizing pipe 19. In this constitution, a priming operation can be conducted even when one of the pumps 13 is operating. In addition, even when the pump 13 is stopped, the pressure in the pump 13 is not reduced to a negative pressure. Therefore, air is not sucked in through a bearing part and there is no need for priming. Accordingly, the pumps can be operated in parallel and the number of the pumps operated can be controlled.
