Optimization method of water supply system
The invention discloses an optimization method of a water supply system. The optimization method of the water supply system comprises the following steps that a pressure gauge is installed in an outlet main pipe of a pump; a resistance coefficient K between the pressure gauge and a water supply point is calculated; according to the water demand Q of the water supply system, the hydraulic loss hf'before the gauge from the water surface of a water getting point to the pressure gauge is calculated; according to the water demand Q of the water supply system and the hydraulic loss hf' before the gauge from the water surface of the water getting point to the pressure gauge, the lift H of the pump is calculated; and the pump is redesigned according to the calculated resistance coefficient K andthe lift H required by the pump under the water demand Q. According to the optimization method of the water supply system, the resistance coefficient K between the pressure gauge and the water supply point and the lift H of the pump are calculated according to data measured when an existing water supply system works under different working conditions, the pump more in line with the current water supply system is redesigned according to calculated parameters, and the energy consumption of the water supply system is saved.
