Vector modulation pipe network pressure-superposed water supply unit
The invention discloses a vector modulation pipe network pressure-superposed water supply unit. The vector modulation pipe network pressure-superposed water supply unit is mainly composed of a filtering device, a backflow-prevention device, a flow measuring device, a non-negative-pressure pipe network pressure-superposed flow stabilization compensation device, a centrifugal pump, a speed regulation permanent magnet motor and a non-negative-pressure vector frequency control cabinet. The centrifugal pump is driven by the speed regulating permanent magnet motor, and the centrifugal pump and the speed regulating permanent magnet motor are installed in a matched mode; the non-negative-pressure vector frequency control cabinet is provided with an intelligent electric quantity monitoring device, a vector frequency converter, a non-negative-pressure vector controller and a touch screen so as to be used for achieving the functions such as automatic control, vector frequency water supply, man-machine fixing, water pressure, water amount and electric quantity monitoring and analyzing, data storage, displaying and monitoring and the like. The vector modulation pipe network pressure-superposed water supply unit has the beneficial effects that the vector modulation pipe network pressure-superposed water supply unit can be directly connected with a tap water pressure water inlet pipe for water supply in series, the effects of being free of negative pressure and free of pollution, achieving frequency-conversion constant voltage, achieving pipe network pressure-superposed energy saving and the like are achieved; in addition, the speed regulating permanent magnet motor and the centrifugal pump are used in a matched mode for achieving servo control; and the energy-saving effect is further improved.
