德耐尔微油螺杆式压缩机-可变流量控制DAV

可变流量控制 Variable Flow Control
变频器是根据实际用气量实时调整电机转速，来控制排气量的；用气量低的时候可以让空压机自动休眠，从而就大大减少能源的损失；优化的控制策略，可进一步改善节能效果。
The frequency converter controls the exhaust volume by adjusting the motor speed in real timeaccording to the actual gas consumption;When the gas consumption is low, the air compressolcan automatically sleep, thus greatly reducing the loss of energy,;The optimized controlstrategy can furtherimprove the energy-saving effect.

低噪音 Low Noise
稳定运行时运行频率小于工频，机械噪音下降,机械磨损减小;若风机也采用变频驱动,能显著降低空压机,工作时的噪音。
During stable operation, the operating frequency is less than the power frequency, themechanical noise is reduced, and the mechanical wear is reduced;lf the fan is also driven byfrequency conversion, the noise of the air compressor during operation can be significantlyreduced.
