KY900E Series Industrial Air Compressor Dedicated Variable Frequency Drive
The industrial air compressor frequency converter developed by our company is a frequency conversion speed control device designed specifically for air compressors. By adjusting the motor speed, it achieves stable air supply pressure, energy saving and consumption reduction, and extends equipment life. It is the core control equipment of modern industrial compressed air systems.
Technical Principles
Variable Frequency Speed Regulation Technology
Principle: By adjusting the input frequency of the motor, the speed can be infinitely adjusted. For example, when the gas consumption decreases, the frequency converter reduces the motor speed to 60% of the rated value, and the power consumption can be reduced to 36% (power is proportional to the cube of speed).
Key parameters: speed range 0-50Hz, frequency resolution 0.01Hz, dynamic response time<50ms.
Closed Loop Control System
Pressure feedback: Real time monitoring of pipeline pressure is achieved through pressure sensors, and the frequency converter automatically adjusts the motor speed to maintain a constant pressure (such as ± 0.1 bar).
Control algorithm: Built in PID regulator, supporting multi machine linkage control.
Product Advantages
Energy Saving
Energy saving loading: reduces pressure operation by 10% compared to traditional air compressors, and reduces power consumption by 10%.
Unloading energy saving: The energy consumption during uninstallation is only 40% of that during loading, with a comprehensive energy saving rate of 20% -50%.
Case: After the renovation of a chemical plant, an annual energy saving of 400000 kWh was achieved, resulting in a savings of 40000 dollars in electricity bills.
Equipment protection
Soft start: The starting current is ≤ 2 times the rated current, reducing the impact on the power grid and machinery.
Extended lifespan: 50% reduction in bearing wear and doubling of lubricant replacement cycle.
Productivity
Stable gas supply pressure reduces product defect rate by 15%.
Support remote monitoring and fault warning to reduce downtime.
Key Selection Points
Compressor type matching
Applicable models: screw, vortex, centrifugal air compressors.
Not applicable model: skateboard type air compressor (due to mechanical structure limitations).
Frequency converter performance
Power matching: Select according to 1.2-1.5 times the rated power of the compressor.
Environmental adaptability: Protection level ≥ IP54, working temperature -10 ℃ to+50 ℃.
Control mode: Supports V/F control, Vector Control (SVC), and Direct Torque Control (DTC).
Functional requirement
Energy saving function: load adaptive, waste heat recovery interface.
Protection functions: overvoltage, undervoltage, overload, phase loss, grounding protection.
Communication function: Supports protocols such as Modbus, Profibus, Ethernet/IP, etc.
