| 发明名称 | Pump control and method | ||
| 摘要 | A pump control (20) and method are provided for controlling a pump (16) for a pressurized liquid supply system (10). The pump control (20) includes a controller (38) configured to provide at least two selectable modes of pump operation as follows: a flow start mode wherein the controller (38) starts the pump (16) in response to a desired start flow rate of the liquid in the system (10) and stops the pump (16) in response to a desired stopping low flow rate of the liquid in the system; anda pressure start mode wherein the controller (38) starts the pump (16) in response to a desired start pressure of the liquid in the system (10) and stops the pump (16) in response to the desired stopping low flow rate. | ||

| 主权项 | 1. A pump control for controlling a pump for a pressurized liquid supply system, the pump control comprising: a controller configured to provide at least two user selectable modes of pump operation as follows: a user interface operably connected to the controller to allow a user to select between the at least two user selectable modes of pump operation; a flow start mode wherein the controller starts the pump in response to a desired start flow rate of the liquid in the system and stops the pump in response to a desired stopping low flow rate of the liquid in the system; and a pressure start mode wherein the controller starts the pump solely in response to a desired start pressure of the liquid in the system and stops the pump in response to the desired stopping low flow rate. | ||
