Abstract
PURPOSE: To improve safety of a water supply passage by intermittently controlling a pump and a valve according to the number of revolution of the pump and the amount of supplied water, permitting the pressure in the conduit system to be varied little by little and preventing said pressure from exceeding the safety pressure of the water feeding conduit even in a transition state.
CONSTITUTION: In a pump P, a tachometer generator N for detecting the number of revolution is installed, and a revolution number signal is supplied to an alarm setting device A1. When the number of revolution reaches prescribed values n1 and n2, the alarm setting device A1 supplies each output signal to a sequence circuit C. A flow meter F supplies a flow amount signal to an alarm setting device A2, and when the flow amount reaches Q1 which is the boundary between the maximum flow amount and the small flow amount, the alarm setting device A2 supplies output signal to the sequence circuit C. The number of revolution of the pump P and the turning of a valve are controlled intermittently, and the time interval in control is varied according to the number of revolution of the pump P and the flow amount, and the limit pressure in the water feeding conduit is prevented at all times from being exceeded, and the safety of the water feeding passage can be improved.
