Methods to characterize hydraulic pump degradation include analyzing various signals and measurements to identify specific indicators or patterns that may indicate pump degradation or impending failure. The following are some common methods used to extract the degradation characteristics of hydraulic pumps: 1. Vibration Analysis: Vibration signals from a pump can provide valuable information about its condition. By analyzing vibration modes and frequencies, abnormal vibrations caused by worn parts, misalignment or imbalance can be detected. Advanced signal processing techniques, such as Fast Fourier Transform (FFT) analysis or wavelet analysis, can be used to extract degradation features from vibration signals. 2. Acoustic analysis: Acoustic signals from the pump can also indicate degradation. Unusual noises, such as knocking, squealing, or rattling, may indicate problems with bearings, valves, or other internal components. Acoustic analysis techniques, such as sound intensity measurements or spectral analysis, can be used to identify degradation signatures associated with specific frequency ranges or sound characteristics. 3. Temperature Monitoring: Monitoring the temperature of various components within a hydraulic pump can help identify abnormal heating patterns associated with degradation. Temperature sensors or thermal imaging can be used to detect temperature anomalies caused by friction, excessive wear or insufficient lubrication. Analyzing temperature trends and changes can provide valuable degradation signatures and insights. 90-R-100-HF-1-BC-60-R-3-F1-E-00-GBA-29-29-24 90R100HF1BC60R3F1E00GBA292924 90-R-100-HF-1-BC-60-P-3-S1-F-00-GBA-17-42-24 90R100HF1BC60P3S1F00GBA174224 90-R-100-HF-1-AB-81-R-3-S1-F-00-GBA-35-35-24 90R100HF1AB81R3S1F00GBA353524 90-R-100-HF-1-AB-80-S-3-C7-E-03-GBA-35-35-24 90R100HF1AB80S3C7E03GBA353524 90R100-HF-1-AB-80-S-3-C7-E-03-GBA-35-35-24 90R100HF1AB80S3C7E03GBA353524 90-R-100-HF-1-AB-80-R-4-S1-F-03-GBA-32-32-24 90R100HF1AB80R4S1F03GBA323224 90-R-100-HF-1-AB-80-R-3-T2-F-03-GBA-26-26-24 90R100HF1AB80R3T2F03GBA262624 90-R-100-HF-1-AB-80-L-4-F1-F-00-GBA-29-14-24 90R100HF1AB80L4F1F00GBA291424 90-R-100-HF-1-AB-80-L-3-S1-F-03-GBA-32-32-24 90R100HF1AB80L3S1F03GBA323224 90-R-100-HF-1-AB-60-P-4-C7-F-02-GBA-26-26-28 90R100HF1AB60P4C7F02GBA262628 90-R-100-HF-1-AB-60-P-3-C7-E-03-GBA-35-35-24 90R100HF1AB60P3C7E03GBA353524 90R100-HF-1-AB-60-P-3-C7-E-03-GBA-35-35-24 90R100HF1AB60P3C7E03GBA353524 90-R-100-DD-5-NN-80-S-7-C7-F-G1-FAC-35-35-30 90R100DD5NN80S7C7FG1FAC353530 90R100-DD-5-NN-80-S-7-C7-F-G1-FAC-35-35-30 90R100DD5NN80S7C7FG1FAC353530 90-R-100-DD-5-NN-80-S-4-C7-E-GB-GBA-26-26-24 90R100DD5NN80S4C7EGBGBA262624 90R100-DD-5-NN-80-S-4-C7-E-GB-GBA-26-26-24 90R100DD5NN80S4C7EGBGBA262624 90-R-100-DD-5-NN-80-R-4-S1-E-GB-GBA-35-35-24 90R100DD5NN80R4S1EGBGBA353524 90R100-DD-5-NN-80-R-4-S1-E-GB-GBA-35-35-24 90R100DD5NN80R4S1EGBGBA353524 90-R-100-DD-5-NN-80-L-4-S1-D-GB-GBA-42-42-30 90R100DD5NN80L4S1DGBGBA424230 90R100-DD-5-NN-80-L-4-S1-D-GB-GBA-42-42-30 90R100DD5NN80L4S1DGBGBA424230 4.

Time domain analysis: Time domain analysis involves studying time series data obtained from sensors to extract degradation features. The analysis focuses on parameters such as amplitude, frequency, and shape of the signal. By tracking changes in these parameters over time, deviations from normal behavior can be identified, indicating potential degradation or impending failure of the pump. 9. Frequency domain analysis: Frequency domain analysis involves converting a time domain signal into a frequency domain signal using techniques such as Fourier analysis or spectrum analysis. This analysis helps identify specific frequency components associated with degradation, such as harmonics, sidebands, or resonant frequencies. By analyzing the frequency content of a signal, it is possible to extract degradation signatures associated with specific components or phenomena. 10. Trend analysis: Trend analysis involves monitoring the long-term behavior of a particular parameter or variable over time. By tracking measurement trends, such as vibration levels, temperature, pressure or flow rate, gradual changes that may indicate degradation can be identified. Trend analysis helps predict remaining pump life and proactively plan maintenance activities. 11. Comparative Analysis: Comparative analysis involves comparing current measurements with reference data or an established baseline. By establishing a baseline of normal operating conditions, any deviation from the baseline can be identified as a degraded signature. This approach helps detect anomalies and anomalies in pump performance and enables early detection of degradation. 90-R-100-DD-5-CD-80-S-3-C7-E-G8-GBA-42-42-24 90R100DD5CD80S3C7EG8GBA424224 90R100-DD-5-CD-80-S-3-C7-E-G8-GBA-42-42-24 90R100DD5CD80S3C7EG8GBA424224 90-R-100-DD-5-CD-80-R-4-C7-E-GB-GBA-35-35-24 90R100DD5CD80R4C7EGBGBA353524 90R100-DD-5-CD-80-R-4-C7-E-GB-GBA-35-35-24 90R100DD5CD80R4C7EGBGBA353524 90-R-100-DD-5-CD-80-R-4-C7-E-GB-GBA-20-20-24 90R100DD5CD80R4C7EGBGBA202024 90R100-DD-5-CD-80-R-4-C7-E-GB-GBA-20-20-24 90R100DD5CD80R4C7EGGBGBA202024 90-R-100-DD-5-CD-80-P-3-C7-E-GB-GBA-30-30-24 90R100DD5CD80P3C7EGBGBA303024 90-R-100-DD-5-CD-80-L-4-F1-F-GB-GBA-35-35-24 90R100DD5CD80L4F1FGBGBA353524 90R100-DD-5-CD-80-L-4-F1-F-GB-GBA-35-35-24 90R100DD5CD80L4F1FGBGBA353524 90-R-100-DD-5-CD-80-L-3-C7-F-G1-FAC-35-35-30 90R100DD5CD80L3C7FG1FAC353530 90R100-DD-5-CD-80-L-3-C7-F-G1-FAC-35-35-30 90R100DD5CD80L3C7FG1FAC353530 90-R-100-DD-5-CD-60-P-4-T2-E-G8-GBA-35-35-24 90R100DD5CD60P4T2EG8GBA353524 90-R-100-DD-5-CD-60-L-4-C7-E-G1-GBA-35-35-24 90R100DD5CD60L4C7EG1GBA353524 90R100-DD-5-CD-60-L-4-C7-E-G1-GBA-35-35-24 90R100DD5CD60L4C7EG1GBA353524 90-R-100-DD-5-BC-80-S-4-C7-E-GB-GBA-32-32-24 90R100DD5BC80S4C7EGBGBA323224 90R100-DD-5-BC-80-S-4-C7-E-GB-GBA-32-32-24 90R100DD5BC80S4C7EGGBGBA323224 90-R-100-DD-5-BC-80-S-3-S1-E-G8-GBA-42-42-24 90R100DD5BC80S3S1EG8GBA424224 90R100-DD-5-BC-80-S-3-S1-E-G8-GBA-42-42-24 90R100DD5BC80S3S1EG8GBA424224 90-R-100-DD-5-BC-60-S-4-S1-E-GB-GBA-42-42-24 90R100DD5BC60S4S1EGBGBA424224 90R100-DD-5-BC-60-S-4-S1-E-GB-GBA-42-42-24 90R100DD5BC60S4S1EGBGBA424224 12.
