ACI Municipal Administration Water Pump Dedicated Frequency Converter

The municipal water pump dedicated frequency converter is a frequency conversion control device designed specifically for municipal water pump systems. It achieves precise control of water pump flow and pressure by adjusting the motor speed, and has the characteristics of high efficiency, energy saving, stability, and reliability.

The pump flow rate is proportional to the motor speed, the pump head is proportional to the square of the motor speed, and the pump shaft power is equal to the product of the flow rate and head. Therefore, the pump shaft power is proportional to the third power of the pump speed. The frequency converter adjusts the motor speed by changing the power frequency, thereby changing the flow rate and head of the water pump, achieving energy saving and precise control.

Key Features

1. Efficient and energy-saving: It can achieve a 20% -40% power saving and green electricity consumption.
2. Flexible configuration: high degree of automation, complete functions, flexible and reliable.
3. Reasonable operation: Soft start and soft stop can eliminate the water hammer effect, reduce the average torque and wear on the motor shaft, reduce maintenance volume and costs, and improve the service life of the water pump.
4. Reduce pollution: Variable frequency constant pressure speed regulation directly supplies water from the water source, reducing secondary pollution from the original water supply method and preventing many infectious diseases from spreading from the source.
5. Communication control: It can achieve unmanned operation and save manpower and material resources.

Selection suggestions

• Clear requirements: Determine the model and number of water pumps based on actual water supply needs, and then select the frequency converter.
• Type of load: Such as vane pumps or volumetric pumps, and pay special attention to the performance curve of the load.
• Matching parameters:
  Voltage matching: The rated voltage of the frequency converter matches the rated voltage of the load.
  Current matching: For ordinary centrifugal pumps, the rated current of the frequency converter matches the rated current of the motor. For special loads such as deep water pumps, it is necessary to refer to the motor performance parameters to determine the inverter current and overload capacity based on the maximum current.
• Special application scenarios: such as high temperature, high altitude, etc., can cause a reduction in the capacity of the frequency converter, and the capacity of the frequency converter needs to be increased by one gear.
