    摘要： At least one computer-readable medium on which are stored instructions that, when executed by at least one processing device, enable the processing device to perform a method. The method includes determining a peak-efficiency range of a set of one or more pumps. The peak-efficiency range has an upper limit and a lower limit. The upper limit has an associated stage-down pump speed and the lower limit has an associated stage-up pump speed. The pump speed of the set of one or more pumps is determined. If the pump speed of the set of one or more pumps exceeds the stage-down pump speed, an operating pump of the set of one or more pumps is deactivated. If the pump speed of the set of one or more pumps falls below the stage-up pump speed, an operating pump is added to the set of one or more pumps.

    摘要： A pump, such as a transmission oil pump, is disclosed. The pump includes an electric motor having a motor housing with a housing wall, and a pump device having a pump housing. A drive shaft of the electric motor is coupled to the pump device. The pump also includes an electrics housing with a motor controller for controlling the electric motor. The electrics housing is detachably attached to the pump housing on a side of the pump housing that faces away from the electric motor. The housing wall of the motor housing is designed as a bearing plate and is detachably arranged on the motor housing rim of the motor housing in the region of a groove which encircles the rim of the bearing plate. The pump housing is detachably arranged by an edge encircling the inside of the pump housing rim, on the bearing plate of the electric motor.

    摘要： Systems and methods of restarting a downhole pump for pumping downhole fluid and located in a wellbore that include determining a pump reverse rotational frequency of a downhole pump caused by downhole fluid flowing in a downhole direction using a phase locked loop. A pump motor is driven at a motor reverse rotational frequency matching the pump reverse rotational frequency. The pump motor is then driven to accelerate the pump reverse rotational frequency and thereby pump the downhole fluid in an uphole direction. The pump motor is then driven to decrease the pump reverse rotational frequency while continuing to pump the downhole fluid in the uphole direction. The pump motor is then driven to change the rotation of the downhole pump to a forward rotation at a pump forward rotational frequency to pump the downhole fluid in the uphole direction.
