Abstract: Now screw pump has been widely used in oilfield exploitation. As important equipment for controlling and regulating the speed of screw pump, the inverter exerts direct effect on stable oilfield operation and energy efficiency for its operation and use. According to the structural characteristics and working principle of inverter, this paper summed up its common faults, analyzed the causes of three common faults such as overload, pressure due and retrograde of electric machine, and proposed corresponding solutions.
