德耐尔微油螺杆式压缩机-变频系列 DAV-185

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 frequency soft start, stable linear operation, no peak current of traditional direct startand Y -  start, effectively improve the service life of motor and electromagnetic contactor, andavoid 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 pointof the frequency converter, and can be started smoothly through the controller or the PIDregulator inside the frequency converter; In case of large fluctuation of gas consumption,quickly adjust the response. Compared with the upper and lower limit switch control of powerfrequency operation, the air pressure stability is improved exponentially.
