課題
スクリューエアコンプレッサは産業分野で広く使われる容積式圧縮機です。高効率・安定性・低メンテナンス・連続送気の特徴を持ち、現代工場で最も主流の圧縮空気設備の一つです。// 従来の定速（定周波数）コンプレッサは「全速運転」か「停止」しかできず、空気需要が減ると無負荷運転や頻繁な起動停止が発生し、大きなエネルギー浪費につながります。// 一方、インバータは電源周波数を変えてモータ速度を制御し、次の効果を実現します：// ✅ 必要量に応じた送気：吐出空気量が実際の需要に適合。// ✅ 定圧送気：システム圧力を安定に維持。// ✅ 省エネ：無負荷運転と頻繁な起動停止を解消。
ソリューション
Inverter achieves stepless speed regulation of the motor by adjusting the frequency and voltage of the motor's input power supply. This in turn controls the rotational speed of the screw airend, ultimately realizing the goals of on-demand air supply, constant-pressure operation, and high-efficiency energy conservation.
In traditional fixed-speed (constant-frequency) screw compressors:
The motor can only operate at "full speed" or be "shut down".
When the air demand decreases, the compressor will enter an "idle load" state (continuing to consume electricity but not producing compressed air) or experience frequent start-stop cycles, leading to energy waste and mechanical impact.
In contrast, variable-frequency screw compressors:
Realize the principle of "producing as much air as needed".
Feature small pressure fluctuations, ensuring a more stable system.
Achieve an energy-saving rate of 20% to 50%, making them particularly suitable for scenarios with large fluctuations in air demand.
