Identifying the dynamic behavior of a seawater hydraulic piston pump under pressure excitation involves analyzing its response to pressure fluctuations and studying various dynamic parameters. The following is a general approach to help you identify the dynamic behavior of this type of pump: 1. Define the excitation source: Determine the nature and characteristics of the pressure excitation the pump will experience. This may include pressure changes due to system operation, water hammer effects, or changes in loading conditions. Know the frequency range, magnitude and duration of pressure fluctuations. 2. Instrumentation: Install appropriate sensors to measure key parameters that help identify the dynamic behavior of the pump. These sensors may include pressure sensors, accelerometers, displacement sensors or strain gauges. Make sure the sensor is suitable for use in seawater environments and can accurately capture the dynamic response of the pump. 3. Data Acquisition: Collect data from sensors during pump operation. Record measurements using a data acquisition system, ensuring it has sufficient sampling rate and resolution to capture the desired dynamic behavior. It is important to synchronize data acquisition with the excitation source to accurately correlate measurements with pressure fluctuations. 4. Frequency analysis: Frequency analysis is performed on the collected data to determine the main frequencies present in the pump response. This can be done by converting the time-domain measurements to the frequency domain using techniques such as the Fast Fourier Transform (FFT). Analyze the frequency spectrum to determine any resonant frequencies or frequency components that contribute significantly to the dynamic behavior of the pump. 90-R-075-MA-1-BB-60-P-3-C6-D-03-GBA-38-38-20 90R075MA1BB60P3C6D03GBA383820 90-R-075-MA-1-BB-60-P-3-C7-C-03-GBA-42-42-24 90R075MA1BB60P3C7C03GBA424224 90-R-075-MA-1-BB-60-P-3-S1-E-03-GBA-42-42-24 90R075MA1BB60P3S1E03GBA424224 90-R-075-MA-1-BB-60-P-4-S1-D-03-GBA-35-35-24 90R075MA1BB60P4S1D03GBA353524 90-R-075-MA-1-BB-60-S-3-C7-D-03-GBA-42-42-24 90R075MA1BB60S3C7D03GBA424224 90-R-075-MA-1-BB-60-S-3-S1-D-03-GBA-26-26-20 90R075MA1BB60S3S1D03GBA262620 90-R-075-MA-1-BB-60-S-3-S1-D-03-GBA-35-35-24 90R075MA1BB60S3S1D03GBA353524 90-R-075-MA-1-BB-61-P-3-S1-E-03-GBA-32-32-24 90R075MA1BB61P3S1E03GBA323224 90R075-MA-1-BB-80-L-4-C7-D-05-GBA-32-32-24 90R075MA1BB80L4C7D05GBA323224 90-R-075-MA-1-BB-80-L-4-C7-D-05-GBA-32-32-24 90R075MA1BB80L4C7D05GBA323224 90-R-075-MA-1-BB-80-S-3-C7-D-03-GBA-42-42-24 90R075MA1BB80S3C7D03GBA424224 90-R-075-MA-1-BB-80-S-3-S1-D-03-GBA-29-29-20 90R075MA1BB80S3S1D03GBA292920 90-R-075-MA-1-BC-60-D-3-S1-L-03-GBA-38-38-24 90R075MA1BC60D3S1L03GBA383824 90-R-075-MA-1-BC-60-P-3-C6-D-03-GBA-26-26-24 90R075MA1BC60P3C6D03GBA262624 90-R-075-MA-1-BC-60-P-3-C6-E-04-GBA-38-38-28 90R075MA1BC60P3C6E04GBA383828 90-R-075-MA-1-BC-60-P-3-C7-D-03-GBA-35-35-24 90R075MA1BC60P3C7D03GBA353524 90-R-075-MA-1-BC-60-P-3-C7-D-03-GBA-42-42-24 90R075MA1BC60P3C7D03GBA424224 90-R-075-MA-1-BC-60-P-3-S1-D-03-GBA-32-32-24 90R075MA1BC60P3S1D03GBA323224 90R075-MA-1-BC-60-P-3-S1-D-03-GBA-32-32-24 90R075MA1BC60P3S1D03GBA323224 90-R-075-MA-1-BC-60-P-3-S1-D-03-GBA-35-35-20 90R075MA1BC60P3S1D03GBA353520 5.
