DREAM DMV screw air compressor can, under the principle of stable discharge pressure, change the rotation speed of the main motor precisely according to the variety of using air capacity, to make the air compressor just discharge the needed air capacity, meanwhile, it also just consumes the energy needed for discharging the compressed air. Therefore, it has achieved the goal of energy-saving, which means the saved energy expense during the operating period of the whole machine far surpass the price of air compressor itself.
圖中顯示的是幾種啟動方式的比較,可以看出變頻機是緩慢地加速啟動,比軟啟動更加平穩,完全避免了電流峰值,在啟動運行至額定壓力后變頻運行。能大程度上適應電力不足的使用環境。
From several start-up modes shown in the chart, we can see that the variable frequency compressor start-up style is of slow to add speed, which more stable than soft start and absolutelyavoid the current peak. After running to the rated pressure, it will operate with variable frequency,which can adapt to the power lacking environment.
恒壓供氣 產用平衡
Constant pressure for air supply with balance
圖中顯示的是普通空壓機與變頻空壓機運行中的狀況比較。變頻機會根據用氣量的變化自由地調節機器的轉速,達到產氣量與用氣量的平衡,這樣避免了機器在用氣量的變化下頻繁加卸載,使得變頻機與傳統壓縮機相比會節省大約35%的能源或更多。平穩的壓力輸出,可以將壓力帶控制在0.01MPa-0.02MPa,避免了傳統壓縮機高達0.05-0.2MPa壓力帶所帶來的高負荷電流損耗。
In the chart, it shows the operating condition between normal air compressor and variable frequency air compressor. According to the various of air requires to adjust the speed of motor to make sure the air output and air requires are balanced, so avoid machine to frequently load and unload during various of air requires, which compared with the traditional compressor , the variable frequency air compressor could save about 35% of energy or more. Stable pressure output can control the pressure between 0.01MPa-0.02MPa, which avoids the high load current lost because of the traditional
compressors’ 0.05-0.2MPa pressure.

據研究表明,變頻壓縮機與普通壓縮機相比,節能效果主要體現在兩個方面:普通壓縮機的空載損耗和壓力波動損耗。以一臺55KW機組,年平均產氣量70%為例,每年可節約電能80000Kwh左右,大約兩年即可收回一臺變頻機的投資成本。
According to research shows that compared with normal compressor, energy-saving effects of variable frequency reflect mainly in two aspects: no-load loss and pressure fluctuation loss of normal compressor. Take a 55KW compressor with average annual air production 70% as example. It can save about 80000Kwh electric energya year and about two years will recover the production cost of a variable frequency compressor.
