Characteristics and Analysis of Frequency Conversion and Speed ​​Regulation of Centrifugal Pump

Users’ water consumption is generally dynamic, so water shortage or excess water situation occurs. And the imbalance between water and water is reflected in the water supply pressure, that is, water and water supply less, the pressure is low; water and water supply more, the pressure is large. Maintain the constant water supply pressure, so
