Working Principle
A permanent magnet frequency conversion air compressor from Sanzhi (Henan) Compressor Co., Ltd. utilizes a sophisticated pressure sensor to instantaneously detect the actual system pressure and air consumption. Through precise electric and frequency converter control, it adjusts the motor speed without altering the motor's torque, thus regulating system pressure seamlessly. When air consumption drops, the inverter air compressor reduces its rotational speed, decreasing compressed air output. Conversely, it increases motor speed when air demand rises, ensuring a stable system pressure and efficient output of compressed air.
With the adoption of advanced vector control technology, our unit operates across a wide speed range, ensuring minimal motor temperature rise. This guarantees appropriate torque to drive the air compressor smoothly. The motor current comprises torque-generating components and other vector control technology components. By optimally distributing these current values, the system compensates for voltage drops at the motor end, enabling maximum torque output without increasing current.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Savings
Our frequency conversion regulation technology effectively reduces power consumption in direct proportion to the compressor's demand. Energy is efficiently applied to air compression, optimizing overall performance.
Cost Reduction
Leveraging permanent magnet frequency conversion technology, we achieve over 35% reduction in energy costs. This translates to an average 22% reduction in the compressor's life cycle cost. The additional investment in the compressor is typically recovered within 1 to 2 years, offering significant cost savings.
Steady Pressure
Using the PID (Proportional, Differential, Integral) method, our exclusive compressor precisely adjusts to maintain stable system pressure, ensuring consistent performance.
Extended Lifespan
Frequency conversion starts minimize the impact on the power grid and machinery, significantly prolonging the compressor's service life.
Top Quality
Incorporating top-quality imported bearings and the latest rotor profile research, our compressors feature large rotors, substantial displacement, low speed, and reduced noise. These enhancements improve efficiency and production quality, setting a new standard in air compression technology.
