The AFT Impulse Pulsation Frequency Analysis module helps:
- Avoid system weakening or failure
- Reduce operating and maintenance costs
- Minimize disruptions in production processes
The AFT Impulse PFA module lets you:
- Predict and understand resonant frequencies in systems that use positive displacement pumps so they can be avoided in operation
- Graphically show the frequency response of a system to a simulated pulse
- Ensure the pressure pulsation magnitudes comply with the API-674 Standard
- Work with existing AFT Impulse models
The module automates most of the pulsation analysis process using a series of steps:
- Build the model in AFT Impulse
- Specify the characteristics of the pulse
- Apply the forcing function to the source of the pulse
- Run the model
- Generate a Bode plot, displaying Frequency vs. Magnitude
For PD Pump pulsations:
- Specify excitation frequencies to analyze from specific pump RPM
- Generate child scenarios for each selected excitation pump RPM
- Run each child scenario and determine resulting acoustic magnitudes
- Automatically compare peak-to-peak pressure pulsation to API 674 requirements
