微油螺杆式压缩机-变频系列(5~400kW)
OIL INJECTED SCREW AIR COMPRESSOR-VARIABLE SPEED DRIVEN SERIES(5~400kW)
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.
