Working Principle
Discover the innovation behind our permanent magnet frequency conversion air compressor system. It is equipped with advanced pressure sensors, deftly monitoring real-time usage pressure and air consumption within the ecosystem. Utilizing precise electronic and frequency converter controls, this state-of-the-art system fine-tunes the motor speed while steadfastly maintaining the motor's torque. This results in a seamless regulation of system pressure, perfectly aligned with the necessary compressed air output. In scenarios where air consumption diminishes, and the compressor's output exceeds demand, the intelligent inverter air compressor gracefully decreases its speed, thus conserving energy by reducing the compressed air output. Conversely, as demand surges, the system elevates the motor speed, amplifying the compressed air supply, thereby ensuring unwavering stability in system pressure.
Harness the power of cutting-edge vector control technology with our advanced unit, offering unparalleled efficiency across a spectrum of speeds, while simultaneously curbing motor temperature rise. This guarantees optimal torque, facilitating the seamless operation of the air compressor. The motor's current is a composite of torque and other values, intelligently optimized through vector control technology. Notably, vector control techniques skillfully address voltage discrepancies at the motor's end, enabling maximum torque output without escalating current levels, ensuring peak performance and reliability.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Our system, with its frequency conversion regulation, vastly diminishes actual power consumption, ensuring every bit of energy is harnessed for maximum air compression efficiency.
Cost Reduction
Thanks to the revolutionary permanent magnet frequency conversion technology, our system slashes energy costs by an impressive 35% and reduces compressor lifecycle expenses by an average of 22%. Typically, the initial investment in the compressor is recovered swiftly within just 1 to 2 years.
Steady Pressure
Through the sophisticated PID (proportional, differential, integral) methodology, our exclusive compressor is meticulously calibrated to uphold exquisite precision in system pressure stability.
Extended Lifespan
By implementing a frequency conversion start mechanism, our system reduces stress on the power grid and mechanical components, thereby significantly prolonging the system's operational lifespan.
