Abstract

PURPOSE: To decrease required power for a pump device so as to promote the saving of energy, by jointly using a main pump, which is started by a pressure detector, and an auxiliary pump which is started by a flow detector.
CONSTITUTION: A level of water decreases lower in an overhead water tank 7, and if the level of water reaches a lower limit water level 21, a water level detector 8 operates releasing an automatic valve 6. Then decreasing a pressure lower in a pumping water main pipe 5 simultaneously allowing water in a pressure tank 14 to flow into the pumping water main pipe 5, a main pump 1 is started by turning on a pressure detector 15. And water in an intake water tank 11 is allowed to flow into the main pump 1 through a suction pipe 10 and into the overhead water tank 7. In this way, the level of water rises, and if it reaches an upper limit water level 22, a device, actuating the water level detector 8, closing the automatic valve 6, generating no flow of water in the pumping water main pipe 5 and actuating a flow detector 4, operates an auxiliary pump 17 to be started. Here the pump device, in which the main pump 1 is still in operation, generates a pressure, in which a delivery pressure of the auxiliary pump 17 is added to the delivery pressure of the main pump 1, in a delivery port of the auxiliary pump 17.
