ACI Low Power Water Pump Dedicated Frequency Converter
A High Power Water Pump Dedicated Frequency Converter is an electrical control device specifically designed for large-scale water pump systems. It achieves stepless speed regulation of the pump motor by adjusting the power supply frequency, thereby optimizing system efficiency, reducing energy consumption, and enhancing operational stability.
Key Features & Technical Advantages
Wide Power Range & High Voltage Compatibility
Supports power ratings from tens to several megawatts, with voltage levels including 380V, 6kV, and 10kV.
Utilizes multi-level power cell cascading (e.g., H-bridge cascade) for direct high-voltage output, eliminating the need for output transformers.
Energy Efficiency & Soft Starting
Reduces pump energy consumption by up to 20%–40% (varies by application).
Enables soft motor starting, limiting inrush current to 1–1.5 times the rated current, minimizing grid impact.
Intelligent Control & Protection
Built-in PID controller for automatic speed regulation based on pressure, flow, or other parameters, maintaining constant pressure/flow operation.
Integrated protection against overload, overvoltage, undervoltage, phase loss, and short circuits.
Environmental Robustness & Durability
Industrial-grade components for operation in harsh environments (high temperature, humidity, dust).
Explosion-proof and corrosion-resistant designs available for chemical plants, mines, etc.
Applications
Municipal Water Supply & Drainage
Ensures constant pressure water supply, preventing pipeline pressure fluctuations.
Adjusts drainage pump speed based on rainfall, reducing energy waste.
Industrial Circulating Water Systems
Optimizes efficiency in cooling water loops for steel, chemical, and power plants.
Reduces pump wear through speed regulation, extending equipment lifespan.
Agricultural Irrigation & Hydraulic Engineering
Automates irrigation flow based on soil moisture and weather conditions, improving water use efficiency.
Enables multi-pump coordination in large pumping stations for flexible scheduling.
Technical Highlights
Vector Control & Torque Compensation
High-performance vector control algorithms for low-speed high-torque output, meeting startup and heavy-load demands.
Torque compensation prevents overheating in low-flow conditions.
Multi-Pump Coordination & Redundancy
Supports parallel operation of multiple pumps with master-slave switching and load balancing.
Redundant design ensures seamless switching to backup units in case of failure.
Remote Monitoring & Diagnostics
Equipped with RS485, Ethernet, and other communication interfaces for integration with SCADA systems.
Built-in self-diagnostics and cloud-based data upload for remote maintenance.
Selection Guidelines
Match Pump Parameters
Consider rated power, voltage, current, and speed to ensure converter capacity compatibility (e.g., a 10kV/1000kW pump requires a ≥1200kVA converter).
