根据自同步振动理论,以PLC为核心,对四电机激振振动筛的变速、周期运行的控制系统进行了设计通过变频技术,改变振动筛激振电机的振动频率,使其随着泥浆返出量的变化而变化,可以有效提高钻井效率。另外,通过控制振动筛激振电机,使其间歇式周期运行,具有同步控制、节约能源、延长激振电机寿命等优点。 According to the theory of self-synchronous vibration, taking PLC as the core, the control system of variable speed, periodic operation of the four-motor vibrating shaker is designed. Through the frequency conversion technology, the vibration frequency of vibration motor is changed, The amount of change and change, can effectively improve drilling efficiency. In addition, by controlling the vibrating screen motor excitation, intermittent periodic operation, with synchronous control, energy conservation, extended excitation motor life and so on.
