当使用深井泵装置采油时,在平稳启动中为减少砂子的有害影响,随着泵的磨损增加为保持产量不变,以及在装置的工作循环内为减少构件的动应力和使抽油机电力拖动装置的负荷曲线平展,所有这些都需要调节抽油机电动机的转数。为降低抽油杆的应力,我们使用脉冲控制的可控硅交流电力拖动系统对深井泵装置进行了按着泵的磨损程度调节抽油机电动机的转数的实验研究。论文介绍有脉冲控钏的可控硅交流电力拖动系统的控制元件和保护元件,同时还
To reduce the harmful effects of sand during smooth start-up when pumping with deep well pumping, to keep the output constant as the pump is worn out, and to minimize the dynamic stresses on the components and the power of the pumping unit during the work cycle of the unit Drag device load curve flat, all of which need to adjust the pumping motor revolution. In order to reduce the stress of the sucker rod, we used a pulse-controlled thyristor AC electric drive system to conduct an experimental study of the deep well pump device to adjust the number of revolutions of the sucker motor according to the wear degree of the pump. The paper introduces a pulse control 钏 SCR AC power drive system control components and protection components, but also
