We are experiencing excessive vibration on the pump side. Can you provide recommendations to resolve this issue? The motor's horizontal vibration is 2.3 mm/s, vertical vibration is 2.6 mm/s, and axial vibration is 3.5 mm/s. On the pump side, the horizontal vibration is 6.5 mm/s, vertical vibration is 4.5 mm/s, and axial vibration is 5.5 mm/s. How can we reduce these vibrations for optimal pump performance?
Hello Mr. Vishal, I hope this message finds you well. In order to provide an accurate analysis, we require more information as per ISO recommendations. This includes the pump capacity or kilowatt range, acceptable vibration levels, and overall condition assessment. To identify the root cause of the vibration, please forward the time and Fast Fourier Transform (FFT) drawings at your earliest convenience. Thank you, Chary
Based on your measurements, it seems like there could be an issue with the pump's alignment or perhaps the bearing. Misalignment can significantly contribute to increased vibrations. I'd suggest checking the pump and motor alignment, and double-checking for any signs of bearing wear and tear as your first course of action. One more point worth considering is to check for cavitation, it can produce high vibrations and damage the pump over time. Ultimately, a comprehensive examination should help pinpoint the root cause and determine the best action to take for reducing the excessive vibrations in your system.
Your vibration levels appear unusually high, especially on the pump side. This could indicate a range of issues, from incorrect alignment to impeller imbalance or bearing wear. Begin by ensuring the pump and motor are properly aligned, as even tiny misalignments can cause significant vibrations. Concurrently, inspect the bearings and impeller for wear or damage. If these checks don't reduce the vibration, you could also consider using vibration dampers or isolators, designed to absorb equipment vibration. It's pivotal to consult with a trusted engineer or a technical specialist for a comprehensive evaluation, as these kinds of issues can escalate if not addressed correctly.
