US 2010/0254827 A1 · Method and Auto-control System on Improving Pumping System Performance

Abstract

The present invention discloses a method and auto-control system on improving pumping system performance. The system contains a pump, a pool, pipelines, a parameter setting module, a water level measuring module and a system control module. The parameter setting module is configured to preset a characteristic parameter and a control parameter of the pump and the pipelines. The water level measuring module is configured to measure, determine and compute a high level pool water level, a flow demand trend and a system instantaneous flow at regular intervals. The system control module is configured to receive the data sent by the water level measuring module that is measured and computed, and controls the operation of the system based on the data. The method and auto-control system on improving pumping system performance in the present invention is able to automatically measure and predict the flow demand of the pipeline system, and controls the pumping system to operating in high efficiency zone in most of the time. Compared to existing pumping control system, the system in the present invention can save energy for 10%-30%.
