<P>PROBLEM TO BE SOLVED: To provide a water supply device capable of stabilizing a water supply pressure when renewing a target pressure of terminal pressure constant control (or discharge pressure constant control). <P>SOLUTION: In the water supply device including a pump connected to a water supply pipe to supply water, an inverter driving the pump at a variable speed, a pressure detection means detecting a pressure at a discharge side of the pump, a target pressure setting means for setting a target pressure at the discharge side of the pump, and a control unit controlling the inverter so that the pressure detected by the pressure detection means becomes the target pressure. When a set time has elapsed while the pressure detected by the pressure detection means reaches the target pressure, the target pressure is renewed by the target pressure setting means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
