Abstract
A method of monitoring integrity of a pump. The method may include recording timing information of the pump during operation while simultaneously sampling acoustic data with a high speed equidistant acquisition mechanism or at a rate based on the speed of the pump in operation. The acquisition of acoustic data is followed by evaluation thereof. Such techniques may improve resolution of acquired data while substantially increasing processor capacity for evaluation. A pump integrity monitor for carrying out such techniques is also described.
Claims22
A method, comprising:
- operating a pump assembly comprising a prime mover and a pump;
- determining timing information corresponding to one of the prime mover and the pump;
- sampling acoustic data with a high speed acquisition mechanism of the pump assembly;
- discerning by a processor acoustic data from the pump assembly and acoustic data from other pump assemblies or equipment in response to the timing information so as to determine an unhealthy condition of the pump assembly.
A pump integrity monitor, comprising:
- a sensor structured to monitor operational timing information one of a prime mover and a pump;
- a data sensor structured to sample harmonics of a pump assembly comprising the primer mover and the pump;
- a processor coupled to the sensor and the data sensor, the processor structured to:
- discerning acoustic data from the pump assembly and acoustic data from other pump assemblies or equipment in response to the operational timing information so as to determine an unhealthy condition of the pump assembly.
A system, comprising a first pump assembly including a first pump, a first prime mover, and a pump integrity monitor, the pump integrity monitor comprising:
- a sensor structured to monitor operational timing information one of the first prime mover and the first pump;
- a data sensor structured to sample harmonics of the pump assembly;
- and
- a processor coupled to the sensor and the data sensor, the processor structured to discerning acoustic data from the first pump assembly and acoustic data from a second pump assembly in response to the operational timing information so as to determine an unhealthy condition of the first pump assembly.
