Abstract
A method of monitoring a condition of a dynamic system includes installing a vibration signal acquisition device at a predetermined location of the dynamic system, acquiring vibration signals by the vibration signal acquisition device, analyzing the vibration signals in a frequency domain, and predicting a change in the condition of the dynamic system based on the vibration signals in the frequency domain. A system is also provided, and a condition of the dynamic system includes clogging.
Claims20
A method of monitoring a condition of a dynamic system, the method comprising:
- generating a vibration spectrum based on vibration signals acquired from a vibration signal acquisition device, the vibration signal acquisition device being located at a predetermined location of the dynamic system;
- determining a plurality of amplitude differences between the vibration spectrum and a baseline vibration spectrum for a plurality of frequency values, wherein each amplitude difference from among the plurality of amplitude difference is associated with a given frequency value from among the plurality of frequency values;
- identifying, in a frequency domain, a frequency peak based on a largest amplitude difference from among the plurality of amplitude differences;
- correlating the frequency peak to a presence of the clog of the dynamic system;
- and
- selectively removing the clog based on the presence of the clog.
A system for clog detection in a fluid flow conduit of a dynamic system, the system for clog detection comprising:
- a plurality of operational components;
- a vibration signal acquisition device disposed at a predetermined location of at least one of the plurality of operational components, the vibrational signal acquisition device configured to acquire vibration signals associated with the plurality of operational components;
- and
- a controller configured to:
- generate a vibration spectrum based on the vibration signals;
- determine a plurality of amplitude differences between the vibration spectrum and a baseline vibration spectrum for a plurality of frequency values, wherein each amplitude difference from among the plurality of amplitude difference is associated with a given frequency value from among the plurality of frequency values;
- identify, in a frequency domain, a frequency peak based on a largest amplitude difference from among the plurality of amplitude differences;
- determine a presence of a clog based on the frequency peak;
- and
- selectively broadcast a command to remove the clog based on the presence of the clog, wherein the command includes at least one of activating a heater to remove the clog and introducing a gas within the fluid flow conduit to remove the clog.
