启动优势 starting Advantages
变频软性启动,线性运转平稳,无传统的直接启动与Y-△启动的峰值电流,有效提高了马达及电磁接触器的使用寿命,同时避免用电超负荷被电力部门罚款的风险。
Variable freauency soft start, stable linear operation, no peak current of traditional direct start and Y-△ start, effectively improve the service life of motor and electromagnetic contactor, and avoid the risk of being fined by power department for power overload.

稳压Stable Pressure
变频的螺杆空压机利用了变频器的无级调速点,通过控制器或变频器内部的PID调节器,能平缓启动;对用气量波动比较大的场合,快速调节响应。与工频运行的上下限开关控制相比,气压稳定性成指数级的提高。
The variable-frequency screw air compressor makes use of the stepless speed regulating point of the frequency converter, and can be started smoothly through the controller or the PlD regulator inside the freguency converter; In case of large fluctuation of gas consumption, guickly adjust the response. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.

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 freguency converter controls the exhaust volume by adjusting the motorspeed in real time according to the actual gas consumption:When the gas consumption is low, the air compressor can automatically sleep, thus greatly reducing the loss of energy;The optimized control strategy can further improve 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, the mechanical noise is reduced, and the mechanical wear is reduced;lf the fan is also driven by trequency conversion, the noise of the air compressor during operation can be significantly reduced.

杜绝高压低用
Eliminate the use of high pressure for low pressure requirements
“高压低用”这种现象很浪费,就像“用不完”一样。普通螺杆机始终6-8bar频繁加卸载工作,实际也就只用了6bar,那么多出来的2bar频繁爬升会让机组多消耗14%(每爬升1公斤约多耗7%的电流)。按频繁爬升时间累计是70%,这样一台110KW的普通空压机会因70%的频繁加载多浪费60300元/年。同样如果是变频空压机它始终保持6bar不变的供气,那么也就不存在这2bar的爬升损耗了。
The phenomenon of "high voltage and low use" is wasteful, just like "endless use". The ordinary screw machine is always loaded and unloaded frequently at 6-8bar, but actually only uses 6bar. The extra 2bar of frequent climbing will cause the unit to consume 14% more current (about 7%6 more current per lkg of climbing). The accumulative time of frequent climbing is 70%, and such a 110KW ordinary air compressor will waste 60300 yuan/year due to 7096 frequent loading. Similarly, if the variable frequency air compressor keeps the same air supply of 6bar, there will be no climbing loss of 2bar.
