在杆式泵的整个免修期内,为了弥补由于泵磨损而降低的产量,以及改善深井泵构件的工作条件,势必要调节抽油机的冲数。为此,研制成可控硅交流电力拖动装置。图1是该装置的方块原理图。绕线式异步拖动电动机的转速由接在转子整流电路中了
It is imperative to adjust the pumping unit stroke to compensate for the reduced throughput due to pump wear and to improve the working conditions of the deep well pump components throughout the life of the rod pump. To this end, developed into a SCR AC electric drive. Figure 1 is a block diagram of the device. Winding asynchronous motor speed by the rotor rectifier circuit in the
