ACI Energy Saving Submersible Well Pump VFD Controller Frequency Converter

ACI Energy Saving Water Pump Dedicated Frequency Converter

Energy Saving Water Pump Dedicated Frequency Converter is a specialized device designed to control the speed of water pump motors by adjusting the frequency of the power supply, thereby achieving precise control of water flow and pressure while saving energy.

Key Features

1. High Energy Efficiency:
   • Typically achieves energy savings of 20%-60% compared to traditional water supply methods, depending on actual operating conditions.
   • Reduces energy consumption by matching the pump's speed to the actual demand, avoiding unnecessary high-speed operation.
2. Constant Pressure Control:
   • Utilizes advanced pressure sensing technology to maintain stable water pressure, ensuring consistent supply even under varying demand.
   • Supports multi-pump systems with automatic switching and soft start/stop functions, balancing the load and extending equipment lifespan.
3. Intelligent Control:
   • Equipped with PID (Proportional-Integral-Derivative) control algorithms for precise pressure regulation.
   • Features like sleep mode, dry run detection, and automatic energy optimization further enhance efficiency and reliability.
4. Wide Application Range:
   • Suitable for residential, commercial, and industrial water supply systems, including:
     • High-rise buildings and residential communities.
     • Industrial cooling water circulation and boiler feed systems.
     • Central air conditioning systems and water treatment plants.
     • Agricultural irrigation and landscape fountains.
5. Advanced Protection Functions:
   • Includes overcurrent, overvoltage, undervoltage, overload, short circuit, phase loss, and overheat protection.
   • Self-diagnostic capabilities simplify maintenance and reduce downtime.

Technical Specifications

• Power Range: Typically available from 0.75kW to several hundred kW, accommodating various pump sizes.
• Frequency Range: 0-50Hz or higher, depending on the model, allowing for wide-range speed adjustment.
• Control Interface: Supports RS485, Modbus, and other communication protocols for remote monitoring and centralized management.
• Protection Level: Often rated IP55 or higher, suitable for harsh environments.

Advantages

• Soft Start/Stop: Eliminates water hammer effects, reducing wear and tear on the pump and extending its service life.
• Reduced Maintenance: By operating at optimal speeds, the pump experiences less stress, leading to lower maintenance costs.
• Environmental Benefits: Reduces energy consumption and carbon footprint, contributing to sustainable water supply solutions.

Application Examples

• Residential Water Supply: Ensures stable water pressure in high-rise buildings, preventing issues like low pressure on upper floors.
• Industrial Cooling Systems: Maintains precise water flow and pressure for equipment cooling, improving production efficiency.
• Agricultural Irrigation: Optimizes water usage by adjusting pump speed according to soil moisture and crop needs.
