2.Non-negative pressure water supply control principle

Non-negative pressure equipment keeps the pressure of the pipe network constant by adjusting the speed of the pump. When the pressure detected at the system outlet pipe is less than the starting pressure of the equipment, the intelligent frequency conversion control system can automatically adjust the speed of the pump to make the outlet pressure constant. When the pump runs at the power frequency speed but the pressure cannot reach the set pressure, the system starts the P2 and P3 pumps in sequence; as the water consumption decreases, the outlet pressure rises, and the pump speed gradually decreases. If the pump speed drops to the minimum set by the system Speed, the system stops the pump operation according to P3, P2, P1.
