Abstract

Abstract:

In view of the current situation of low operating efficiency, high energy consumption and high operating cost of industrial water supply pumps, an adaptive control algorithm of converter was proposed. The algorithm realized the pump pressure-current self-feedback control process and gave full play to the actual water supply performance of the water supply pump under the pressure control mode.After the technical transformation of the 100% capacity 80CHTA/4 water supply pump, the power saving efficiency of the water supply pump reached 9.568% under the condition that the original water supply capacity was unchanged after the transformation. The proposed method significantly improved the electrical energy efficiency of the water supply system, and provided a reference scheme for energy-saving retrofit work of pumps.

Key words: inverter, water supply system, automatic feedback, energy saving, reduce consumption, adaptive control algorithm
