Title: Controlling method for number of pump to operate
Inventor: IYODA SHINZOU
IPC: F04D15/00
Filed: 1979-07-16
Abstract: PURPOSE: To control number of pumps to operate efficiently by decreasing the number one by one when internal pressure of a pressure tank indicates values between upper and lower bounds at sampling carried out at least twice at interval of a given time.  
     CONSTITUTION: When an outflow from a pressure tank 3 is almost equal to an inflow and an intermediate signal between upper bound and lower bound for internal pressure of the pressure tank 3 is generated at sampling carried out at least twice at interval of a given time, the number of pumps 1... to operate is decreased one by one according to a control signal from a processing unit 9. Then, when all the  pumps are shut down, the internal pressure of the tank 3 comes to indicate a value  below the lower bound, a short signal is generated from a pressure detector 7, a  state wherein two units are put in operation is restored, and where the internal pressure keeps an intermediate value thereafter, the number of pumps is decreased by one after the given sampling passes, and where the pressure becomes short, then the number is increased accordingly, thus controlling the number of pumps to operate efficiently.
