Tantangan
Kompresor udara sekrup adalah kompresor udara positive-displacement yang digunakan luas di sektor industri. Berkarakter efisien, stabil, kebutuhan perawatan rendah, dan suplai udara kontinu, kompresor ini menjadi salah satu peralatan udara terkompresi paling mainstream di pabrik modern. // Kompresor kecepatan-tetap tradisional hanya bisa beroperasi “kecepatan penuh” atau “berhenti”; saat permintaan udara turun, ia masuk operasi tanpa-beban atau siklus start-stop berulang sehingga boros energi besar. // Sebaliknya, inverter mengendalikan kecepatan motor dengan mengubah frekuensi suplai, menghasilkan: // ✅ Suplai udara sesuai kebutuhan: output udara sesuai permintaan nyata. // ✅ Suplai udara tekanan konstan: menjaga tekanan sistem stabil. // ✅ Hemat energi: menghapus operasi tanpa-beban dan start-stop berulang.
Solusi
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.
