Constant-pressure water supply system
The invention provides a constant-pressure water supply system, and belongs to the technical field of water supply equipment. The constant-pressure water supply system comprises a controller, a frequency converter, a water pump and a water flow information acquisition device. Water is pumped from a water source through the water pump and output to a water use side. The water flow information acquisition device is connected with the controller and used for acquiring water flow information of the water use side and sending the water flow information to the controller. The controller is connectedwith the frequency converter and used for sending out a frequency converter frequency controlling signal according to the water flow information and sending the frequency converter frequency controlling signal to the frequency converter. The frequency converter is connected with a servo motor of the water pump and used for controlling the rotating speed of the servo motor according to the frequency controlling signal. The visualization and instantaneity of detection and adjustment of water pressure are realized, the constant-pressure water supply system has the advantages of being low in energy consumption, high in precision and high in automation degree, and the problem of too high power waste can be effectively avoided; and meanwhile, the water pump is controlled by a PLC to perform thestarting, stopping and frequency converting movements of the variable frequency or power frequency, lower errors happen to the rotating speed of the water pump in the adjustment process, and the pressure constancy in the water supply process is ensured.
