Advanced 380V Frequency Converter for Industrial Use

For centrifugal pumps in the chemical industry that transport corrosive liquids such as acids, alkalis, and solvents, the pain points of traditional centrifugal pumps, such as high energy consumption for valve adjustment and large start-up impact, are addressed. It adopts a corrosion-resistant circuit design, suitable for the corrosive gas environment in chemical workshops. Supports PID closed-loop control and can be linked with pipeline pressure sensors to keep the pressure fluctuation during transportation within ±0.01MPa, avoiding the risk of liquid leakage caused by sudden pressure changes. Based on the characteristics of variable torque loads, deep energy conservation is achieved through reduced speed operation, with an electricity-saving rate of 25% to 50%. After the renovation of a 55kW acid and alkali pump in a certain chemical plant, the annual electricity savings exceed 80,000 kilowatt-hours. The soft stop function avoids the "water hammer effect", protects the interface betw…
