永磁变频空压机特点
Characteristics of pemmanent magnet variable frequency air compressor
超低温升设计,压缩机允许长期超低频率下稳定运行;采用闭环矢量控制系统,控制更迅速、调速更精准;频率降低50%以上时压缩机组仍能保持高效运转;压力稳定,精准控制压力波动0.01MPa以内。
Ultra low temperature rise design, the compressor allows stable operation at ultra-low frequency for a long time; The closed loop vector controlsystem is adopted to make the control more rapid and the speed regulation more accurate, The compresor unit can stilloperate eliciently wherthe frequency is reduced by more than 509; The pressure is stable and the pressure fluctuation is accurately controlled within 0.01MPa.
在设定的变频压力下，机组会自动调节,使输出压力始终保持在士0.1bar以内,减少不必要的浪费。(压力每上升1bar,耗电量上升7%)。
Under the set frequency conversion pressure, the unit willautomatically adjust to keep the output pressure within 土0.lbar, reducing unnecessary waste, (The power consumptionincreases by 7%6 every time the pressure increases by 1 bar).
图中显示的是几种启动方式的比较,可以看出变频机是缓慢地加速启动,启动更加平稳,完全避免了电流峰值。
The figure shows the comparison of several startup modes. ltcan be seen that the inverter starts slowly, accelerates, startsmore smoothly,and completely avoids the peak current.
