    • PURPOSE: Operating vacuum pump method and device are provided to free from a dependence on a network voltage and to improve a better power matching by contacting a single phase network and a three phase network with a operating device having a rectifier and intermediate frequency circuit and a power transformer on a controller. CONSTITUTION: A network, including L (phase)and N(conductor), is linked to a rectifier(2), an intermediate frequency transmitter(3) and a power transformer(4). A rotatory current generated from the power transformer(4) operates a motor(6) which controls a pump, and then a controller(5) is connected to a generating a control signal unit(8).
    • 目的:提供操作真空泵方法和装置以免于对网络电压的依赖,并且通过使单相网络和三相网络与具有整流器和中频电路的操作装置接触来提高更好的功率匹配,并且 电源变压器在控制器上。 构成:包括L(相)和N(导体)的网络连接到整流器(2),中频发射器(3)和电源变压器(4)。 从电力变压器(4)产生的旋转电流操作控制泵的马达(6),然后将控制器(5)连接到产生控制信号单元(8)。
