Non-negative Pressure Speed Variable Constant Pressure Water Supply System WG series, this system directly connected in series to the municipal water supply network or a pressure pipe-line network to boost water pressure, and effective take use of the existing pipe network pressure to save energy. Facing the municipal water distribution pipe network in pressure, it does not produce negative pressure. System detects pressure Value through the outlet pressure sensor. Compared with set value and detected value, increasing pressure value will be calculated based on existing pressure of municipal water supply network and the setted value to determine the number of pump units in operation and motor speed, to achieve constant water pressure output. WG system could be apply for intelligent integration of water pump, no switch, soft start, no impact on municipal water supply network that is the new generation of energy-saving water supply equipment, it applied with increasing pressure pipeline network and regulate the flow of the water supply system.
Municipal pipe network water supply is steady flow into the stainless steel adjustable tank, the tank of air exhaust suppressors gradually from the vacuum until the water is full, the vacuum suppressors automatically shut down.
When the municipal water supply pipeline network meet the water pressure and flow requirements, the water from municipal water supply pipeline will flow through a near-pass pipe to water supply pipeline network;
When the municipal water supply pipeline network water pressure is not able to meet requirements, the system send the signal to control center to start pump through the pressure sensor ( or select transmission pressure gauge ). If the municipal water supply pipe network is greater than the amount of water flow pump, system maintain normal water supply; During Water peak, if the municipal water supply pipe network water is low, steady flow regulation tank of water will supply water as a supplemental source of water supply. At this point, the air will come into the tank by the vacuum suppressor to eliminating the negative pressure regulating tank. If the water level of tank is falling gradually due to lack of water supply of municipal water pipeline network, send the signal to control center to stop the water pump. Once the water level is rising to set level, the water pump will starts automatically. When night and low flow water supply ,it will be supplied by the main storage tank and pump water without additional pump.
Non-negative pressure design. System connecting with municipal pipeline network to water supply and pressure boosting operation without negative pressure effect on municipal pipeline network.
Closed laminated design, the pressure on the municipal pipe network booster, energy-saving remarkable.
Integrated Variable Speed Pump design, soft start, low noise, and resistance-water hammer, green.
Outlet pressure test PID control operation to keep water pressure constant and reliable.
