德耐尔微油螺杆式压缩机-两级压缩永磁变频系列：控制更迅速DAV+

永磁变频空压机特点
Characteristics of permanent magnet varable 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-ow frequency for a long time, The closed loop vector control system is adopted to make the control more rapid and the speed repulation more accurate, The compressor unit can stil aperate eficientlywhen the freauency is reduced by more than 50%; The pressure is stable and the pressure fuctuation is accurately controled within 0.0lMPa.

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 freguency conversion pressure, the unit will automatically adjust to keep the output pressure within 0.1bar, reducing unnecessary waste, (The power consumption increases by 7% 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. lt can be seen that the inverter starts slowly, accelerates, starts more smoothly, and comoletely avaids the peak curent.
