FST-650L Intelligent Irrigation System: Precise Constant Pressure Control with 35%-42% Energy Savings, Empowering Smart

2026-04-29
Project Background

A 500-acre agricultural demonstration park (greenhouses and open-field crops) faced a critical inefficiency: pumps running at full speed while actual water demand was only 60%-70% of rated flow, causing oversized pump/undersized load issues, high energy costs, and unstable pipeline pressure.

Key Pain Points:
  • High Energy Consumption: Motors running continuously at full speed, driving up electricity costs
  • Pressure Instability: Dramatic fluctuations with varying demand, affecting sprinkler uniformity
  • Water Hammer Impact: Direct motor starting caused severe water hammer, leading to frequent pipeline leaks
  • Manual Dependency: Required dedicated personnel for valve adjustment, preventing automation
Solution: FST-650L Intelligent VFD Constant Pressure Irrigation System System Architecture
  • Core Control: FST-650L-037G/045P Vector Inverter (37kW/45kW)
  • Sensor Network: Pressure transmitters at pipeline endpoints, real-time 0-10V analog signals
  • Intelligent Algorithm: Built-in PID closed-loop control for automatic speed adjustment
  • Remote Monitoring: RS485 interface integrated with park IoT platform, APP real-time monitoring
Four Core Advantages
Advantage Technical Feature Customer Value
Vector Control Advanced SPWM modulation, high low-frequency torque Sufficient head at reduced speeds for varying elevation zones
Constant Pressure 20Hz-50Hz stepless speed regulation Pressure stability ±0.02MPa, sprinkler uniformity >92%
Smart Sleep/Wake Auto sleep during low demand, millisecond-level wake-up Eliminates frequent start/stops, extends equipment life
Multi-Protection Overvoltage, undervoltage, overload, short circuit, dry-run IP54 rating for harsh outdoor environments
Application Results

After one full irrigation season, the system delivered significant benefits:
