Application Background
In industrial combustion systems, the accuracy and stability of air volume control directly impact combustion efficiency, energy consumption, and operational safety. The customer required a highly reliable air volume regulation system for an 800mm burner damper to meet long-term continuous operation, rapid response, and low maintenance demands. GRAT provided a dedicated guide vane motor control solution, which was put into operation in May 2012 and has been functioning stably since.
Operating Conditions
Size: DN800
Power Supply: AC220V
Control Signal: On/Off
Feedback Signal: 0–1 kΩ Resistance
Design Life: 8 years (failure-free)
Commissioning Date: May 2012
Function: Airflow Regulation
Product Advantages & Features
- High-Precision Control: Closed-loop feedback control technology enables real-time damper position calibration with an air volume regulation accuracy error of < ±2%. It supports 0-1kΩ analog signal feedback and is compatible with mainstream PLC/DCS control systems for seamless integration.
- Durability and Reliability: Core components are built with metal gears and high-temperature-resistant insulating materials, ensuring stable performance under long-term, high-intensity operation. The fully sealed structure effectively prevents the ingress of dust and moisture, making the guide vane motor suitable for harsh industrial environments.
- Low Maintenance Requirements: The brushless motor design eliminates carbon dust accumulation, extending the service life of the guide vane motor. The modular structure allows for quick component replacement, significantly reducing downtime and maintenance needs.
- Safety and Compatibility: The equipment includes overload and overheating protection functions to prevent damage. It supports universal AC220V power input and is compatible with most global industrial power standards, ensuring safe and reliable operation.
Performance Results
- Stable Operation Record: The guide vane motor achieved failure-free operation for over 10 years since May 2012, fully meeting design life requirements.
- Energy Efficiency Improvement: Precise air volume control optimizes combustion air ratio, improving combustion efficiency by approximately 8%.
- Reduced Maintenance Costs: No major failures occurred during the period, with maintenance costs only 30% of the industry average.
- Customer Feedback: The guide vane motor system responds quickly and controls accurately, significantly reducing the frequency of manual intervention, making it suitable for automation upgrade projects.
