摘要： A centrifugal pump system having an impeller rotating with first and second magnetic structures on opposite surfaces. A levitation magnetic structure is disposed at a first end of a pump housing having a levitating magnetic field for axially attracting the first magnetic structure. A multiphase magnetic stator at a second end of the pump housing generates a rotating magnetic field for axially and rotationally attracting the second magnetic structure. A commutator circuit provides a plurality of phase voltages to the stator. A sensing circuit determines respective phase currents. A controller calculates successive commanded values for the phase voltages in response to the determined phase currents and a variable commutation angle. The angle is selected to correspond to an axial attractive force of the stator that maintains a levitation of the impeller at a centered position within the pumping chamber.

摘要： A structural improvement of the canned pump is to improve the stiffness of a stationary shaft and, according to requirement, to dispose a monitor device. The method for improving the stiffness of the stationary shaft includes axially inserting a shaft metal rear support of the metal structural of a motor rear casing of a canned motor into the inner side of a rotor yoke of an inner rotor of the canned motor, tightly attaching the shaft metal rear support to a rear shaft seat for improving the stiffness of the stationary shaft by longer hold length, and for shortening an arm length of the composite force. The monitor device, used for detecting the wear of a bearing for enhancing the reliability and satisfying the driving requirement, is installed in the ring slot to be protected by the rear shaft seat.

摘要： A pump system is disclosed. The pump system may have a power source, a pump, and a torque converter configured to fluidly couple an output rotation of the power source to an input rotation of the pump. The pump system may also have a sensor configured to generate a signal indicative of an output flow rate of the pump, and a controller in communication with the sensor and the power source. The controller may be configured to selectively adjust a speed of the power source based on the signal.

摘要： A system for monitoring an Electrical Submersible Pump is disclosed comprising a rotation rate sensor located in an ESP gauge (6). When the Electrical Submersible Pump is started the rotating elements rotate in a first direction while the static elements will experience an opposing torque in a second opposite direction. The small rotational movement of the ESP gauge housing is sensed by the sensor and is used to determine the initial direction of rotation of the motor (5) and pump (6).

摘要： A system for sensing an axial and radial position of a body rotating about an axis independent of the rotational position of the body. The system includes at least one inductive sensor positioned in proximity to the body. A material forming part of the body effects a variation in the output of the inductive sensor as a function of axial and/or radial movement of the body relative to the axis. Output circuitry analyzes the output of the inductive sensor to produce a system output indicative of the axial and/or radial movement independent of the rotational position of the body.

摘要： A vacuum pump has a housing, a pump shaft having a terminal shaft portion, a bearing member mounted in the housing and supporting the pump shaft and a rotor affixed to the pump shaft. The housing has a housing wall forming a side chamber with the bearing member. The terminal shaft portion projects through the bearing member into the side chamber. There is further provided a device for measuring the rpm of the rotor. The device comprises an inductive sensor held in the housing wall and a ferromagnetic member mounted on the terminal shaft portion for rotation in unison therewith. The ferromagnetic member induces electric pulses in the inductive sensor at a rate proprotionate to the rpm of the rotor. A non-magnetic partition separates the inductive sensor from the side chamber.

摘要： Methods and systems for monitoring a variable-speed pump system to detect a blockage condition. A value indicative of pump performance is sensed and a pump load coefficient is calculated. The value of the pump load coefficient does not change substantially due to changes in pump speed and is indicative of a blockage of a drain in a liquid holding tank. A blockage of the drain is detected based at least in part on the calculated pump load coefficient and the operation of the pump is adjusted based on the detected blockage.
