Abstract
An audio detection unit inside of the pump can be used to capture acoustic waveforms from the pump during operation and, when compared to characterized data, can accurately determine an operating condition of the pump. Such operating conditions can include whether the pump is operating as expected, if it has lost prime, if it has a failure, or if it can be determined that failure is likely to occur in the near future.
Claims20
A method of detecting an operating condition of a pump comprising:
- detecting an acoustic waveform emitted by the pump during operation of the pump;
- comparing the acoustic waveform with a signature waveform, the signature waveform representing normal operation;
- and
- generating an alert when the acoustic waveform deviates from the signature waveform.

A method of detecting an operating condition of a pump comprising:
- detecting an acoustic waveform of the pump during operation by an audio detection unit within the pump;
- determining an acoustic characteristic of the acoustic waveform;
- comparing the acoustic characteristic with a predetermined acoustic characteristic;
- and
- determining the operating condition of the pump based on the compared acoustic characteristic.
2 more elements
A pump comprising:
- a mechanical drive unit comprising a drive mechanism;
- a liquid end comprising a diaphragm, wherein the drive mechanism is configured to translate the diaphragm;
- an electronic drive unit coupled with the mechanical drive unit such that the electronic drive unit is configured to operate the mechanical drive unit;
- and
- an audio detection unit positioned within the pump configured to detect audible noise emitted by the pump during operation, wherein the audio detection unit is coupled with the electronic drive unit such that the electronic drive unit is configured to receive the detected audible noise from the audio detection unit.
