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- Efficient and energy-saving: It can achieve a 20% -40% power saving
and green electricity consumption.
- Flexible configuration: high degree of automation, complete
functions, flexible and reliable.
- 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.
- 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.
- 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.
