Abstract
A method of and system for self-check diagnostics. The system includes a pump control circuit that is configured for operating a first motor to rotate a first gear of a pump and a second motor to rotate a second gear of the pump. The pump control circuit also includes a sensor for determining a position and/or a velocity of the first gear. The system also including a diagnostic circuit that is configured to perform a diagnostic check to determine at least one of a gear wear parameter based on the sensor, a calibration drift of the sensor, or an obstruction in the pump using the sensor.
Claims29
A pump control system, comprising:
- a pump control circuit configured for operating a first motor to rotate a first gear of a pump and a second motor to rotate a second gear of the pump, the pump control circuit including a sensor for determining a position and/or a velocity of the first gear;
- and
- a diagnostic circuit connected to the pump control circuit, the diagnostic circuit configured to perform a diagnostic check to determine at least one of a gear wear parameter based on the sensor, a calibration drift of the sensor, or an obstruction in the pump using the sensor.

A pumping system, comprising:
- a pump assembly having a first motor driving a first gear and a second motor driving a second gear;
- a fluid system connected to the pump assembly;
- and
- a pump control system, wherein the pump control system includes,
- a pump control circuit configured for operating a first motor to rotate a first gear of a pump and a second motor to rotate a second gear of the pump, the pump control circuit including a sensor for determining a position and/or a velocity of the first gear, and
