Abstract
PURPOSE: For ensuring maintenance operation of pumps with actual small water load, to make reflux of the water contained in a suction water tank through the branch pipe connected to a discharge valves and to circulate said water by means of a pump when said water is small in quantity.
CONSTITUTION: The discharge side of the pump 2 provided in the upper section of a suction water tank 1 is connected to the lower section of a suction water tank 4. A branch pipe 9 fitted with another valve 5 is provided between the discharge side of said pump 2 and a discharge valve 3, and the discharge side of said branch pipe 9 is led to said suction water tank 1. Said pump 2 is operated by a motor 6 through the medium of reducing gear 7. When the water contained in said suction water tank 1 is small in quantity, said pump 2 is operated with said discharge valve 3 closed and a valve 5 opened. Then, said small quantity of water flows back into said water tank 1 through said valve 5 and circulates. Thus, the maintenance operation of said pump 2 can be performed with actual small water load.
