| abstract | A water supply device capable of stabilizing a water supply pressure when a target pressure for terminal pressure constant control (or discharge pressure constant control) is updated. A pump connected to a water supply pipe for supplying water, an inverter for driving the pump at a variable speed, current and frequency detection means for detecting current and frequency during inverter operation, and pressure on the discharge side of the pump are detected. In a water supply apparatus comprising: a pressure detecting means that performs a target pressure setting means that sets a target pressure on a discharge side of the pump; and a control unit that controls the inverter so that the pressure detected by the pressure detecting means becomes the target pressure. The inverter current, the inverter frequency, and the target pressure are associated with each other, the target pressure is obtained from the inverter current, and this is used together with the target pressure obtained from the inverter frequency, and the feed water pressure detected by the pressure detecting means is the target pressure. The inverter frequency is controlled so that [Selection] Figure 1 |
