摘要

本文讨论了在工质逆流作用下，工艺储备内的风机或泵叶轮发生旋转现象的原因。详细考虑了风机叶轮或泵的反向旋转方式对电动机的负面影响。本文讨论了在叶轮反向旋转时，风机和抽油机的电驱动的提取方法。结果表明，现有的确定转子初始转速和拾取转子的方法主要集中在电机失电时的自启动，此时转子在法向旋转。提出了一种变频器的拾取方法，该方法可以确定转子的旋转频率和方向，从而保证拾取并成功启动反向旋转的电动机。

The mode of anti-switching of the electric drive during the reverse rotation of the impeller of the fan and pumping units

The article discusses the causes of the occurrence of such a phenomenon as the rotation of the impeller of a fan or pump located in the technological reserve, under the action of a reverse flow of the working medium. The negative consequences of the reverse rotation mode of the fan impeller or pump for the electric motor are considered in detail. The article discusses ways of picking up electric drives of fan and pumping units during reverse rotation of the impeller. It is shown that the existing methods for determining the initial speed and the pickup of the rotor are focused on the self-starting of the electric motor when power is lost, at which the rotor rotates in the normal direction. A method for picking up a frequency converter is proposed, which allows to determine the frequency and direction of rotation of the rotor, thereby ensuring the pickup and successful start of the electric motor with the reverse direction of rotation.
