Pipe network pressure-superposed steady-flow water supply unit
The invention discloses a pipe network pressure-superposed steady-flow water supply unit. The pipe network pressure-superposed steady-flow water supply unit mainly comprises a steady-flow compensation regulator, a no-negative-pressure controller, water pumps, a flowmeter and a teletransmission pressure gauge, wherein the water inlet of the steady-flow compensation regulator is connected with a tap water inlet pipe; the water outlet of the steady-flow compensation regulator is sequentially connected with the water pumps, a water outlet pipe and water using points for water supply; the teletransmission pressure gauge is arranged at a pressure control point of a water using pipe network connected with the water outlet pipe; and a control cabinet is used for monitoring the water inflow rate, the pressure of the steady-flow compensation regulator and the pressure of the water outlet pipe, detecting and controlling the pressure at the pressure control point to be constant, controlling the no-negative-pressure controller to act timely and eliminate negative pressure of the pipe network, controlling the water pumps to automatically start and stop and perform protection, frequency conversion and switching, and also controlling the increase and decrease of working pumps. The pipe network pressure-superposed steady-flow water supply unit has the benefits that the pipe network pressure-superposed steady-flow water supply unit can be directly connected and eliminate suction generated by working of the water pumps, realizes no-negative-pressure variable-frequency water supply and constant-pressure control of any pressure control point of the water outlet pipe, and can achieve an energy-saving effect.
