Full-automatic energy-saving no-negative-pressure pipe network pressure-superposed water supply equipment
The invention discloses full-automatic energy-saving no-negative-pressure pipe network pressure-superposed water supply equipment. The full-automatic energy-saving no-negative-pressure pipe network pressure-superposed water supply equipment mainly comprises a steady-flow compensator, a no-negative-pressure controller, a short shortage transducer, a prepressing pipe, a low-flow pump, main pumps, a pressure protection switch, a flow detection device, a pneumatic water tank and a control cabinet, wherein a check valve III is mounted on the water outlet pipe of each main pump; a bypass pipe II bypasses the main pumps and the check valves III; a check valve I is arranged on the bypass pipe II; small branch pipes are arranged between the check valves III and the corresponding main pumps and in front of the check valve I of the bypass pipe II to be connected with the prepressing pipe; and the prepressing pipe is connected with the pneumatic water tank. The full-automatic energy-saving no-negative-pressure pipe network pressure-superposed water supply equipment has the benefits that the effects of low-flow pressure maintaining, pressure water source providing, flow stabilizing and pressure stabilizing of the pneumatic water tank can be fully utilized, and the low-flow pump is used for water supply to save energy when the flow rate is low, so that a very good energy-saving effect is achieved within a relatively large flow change range, the protection functions are complete, the occupied area is small, the investment is low, and the full-automatic energy-saving no-negative-pressure pipe network pressure-superposed water supply equipment has a very wide development prospect when applied to secondary water supply.
